Background. Shedding of the endothelial glycocalyx layer (EGL) is known to occur during major surgery, but its degradation associated with minimally invasive video-assisted thoracoscopy (VATS) remains unclear. We investigated if serum biomarkers of EGL disruption were elevated during VATS lobectomy, and whether the urinary trypsin inhibitor (UTI) ulinastatin exerted a protective effect during this procedure.Materials and Methods. Sixty ASA II-III lung cancer patients undergoing elective VATS lobectomy were divided equally into UTI and control groups. UTI group patients received intravenous UTI during surgery. Serum levels of syndecan-1 and heparan sulfate were examined before (T0) and at the end of surgery (T1). Serum albumin and hemoglobin were measured before surgery (BOD) and on the first postoperative day (POD1).Results. In control group, syndecan-1 levels were significantly elevated at T1 compared with T0 (3.77±3.15versus4.28±3.30,P=0.022⁎) and increased even more significantly in patients whose surgery lasted >3 h (3.28±2.84versus4.31±3.39,P=0.003⁎⁎). Serum albumin levels on POD1 were significantly lower in control group compared with UTI group (32.63±4.57versus35.76±2.99,P=0.031⁎).Conclusion. EGL degradation occurs following VATS lobectomy. UTI can alleviate this shedding, thus helping preserve normal vascular permeability.Trail Registration. This trial is registered withChiCTR-IOC-17010416(January 13, 2017).

Abstract Purpose Controlled ovarian stimulation significantly amplifies the number of maturing and ovulated follicles as well as ovarian steroid production. The ovarian hyperstimulation syndrome (OHSS) increases capillary permeability and fluid extravasation. Vascular integrity intensely is regulated by an endothelial glycocalyx (EGX) and we have shown that ovulatory cycles are associated with shedding of EGX components. This study investigates if controlled ovarian stimulation impacts on the integrity of the endothelial glycocalyx as this might explain key pathomechanisms of the OHSS. Methods Serum levels of endothelial glycocalyx components of infertility patients (n=18) undergoing controlled ovarian stimulation were compared to a control group of healthy women with regular ovulatory cycles (n=17). Results Patients during luteal phases of controlled ovarian stimulation cycles as compared to normal ovulatory cycles showed significantly increased Syndecan-1 serum concentrations (12.6 ng/ml 6.1125th–19.1375th to 13.9 ng/ml 9.625th–28.975th; p=0.026), indicating shedding and degradation of the EGX. Conclusion A shedding of EGX components during ovarian stimulation has not yet been described. Our study suggests that ovarian stimulation may affect the integrity of the endothelial surface layer and increasing vascular permeability. This could explain key features of the OHSS and provide new ways of prevention of this serious condition of assisted reproduction.

Transarterial chemoembolization (TACE) is usually followed by hepatic dysfunction. We evaluated the effects of L-carnitine on post-TACE impaired liver functions.Methods. 53 cirrhotic hepatocellular carcinoma patients at Osaka Medical College were enrolled in this study and assigned into either L-carnitine group receiving 600 mg oral L-carnitine daily or control group. Liver functions were evaluated at pre-TACE and 1, 4, and 12 weeks after TACE.Results. The L-carnitine group maintained Child-Pugh (CP) score at 1 week after TACE and exhibited significant improvement at 4 weeks after TACE (P<0.01). Conversely, the control group reported a significant CP score deterioration at 1 week (P<0.05) and 12 weeks after TACE (P<0.05). L-carnitine suppressed serum albumin deterioration at 1 week after TACE. There were significant differences between L-carnitine and control groups regarding mean serum albumin changes from baseline to 1 week (P<0.05) and 4 weeks after TACE (P<0.05). L-carnitine caused prothrombin time improvement from baseline to 1, 4 (P<0.05), and 12 weeks after TACE. Total bilirubin mean changes from baseline to 1 week after TACE exhibited significant differences between L-carnitine and control groups (P<0.05). The hepatoprotective effects of L-carnitine were enhanced by branched chain amino acids combination.Conclusion. L-carnitine maintained and improved liver functions after TACE.

Introduction: It is known that increased matrix metalloprotease (MMP) accelerated cardiac remodeling in chronic heart failure (HF). Although roles of MMPs in acute HF have not been well clarified, we also found that MMPs increased in acute HF and decreased in the improvement of HF with conventional therapy. Pharmacological modification of MMPs may be beneficial for a treatment of acute HF. Therefore we assessed the hypothesis that a statin decreased MMPs in acute HF. Methods: Serum levels of MMP-2,-3, and -9 were measured on admission (Day 1), Day 3, and Day 14 in 38 acute HF patients. The patients were randomized to either atorvastatin group (n = 20) or control group (n = 18). Atorvastatin (10 –20mg per day) was started within 12 hours after their admission and continued for two weeks. There was no limitation in HF treatment and the treatment was not different between the two groups except atorvastatin. Patient characteristics including an etiology of HF and cardiac function were also not different between the groups. Results: There were no differences in serum levels of MMP-2, -3, and-9 on Day 1 between atorvastain group (1435.3 ± 292.6 ng/ml, 72.2 ± 40.4 ng/ml, 132.9 ± 85.5 ng/ml, respectively) and control group(1284.5 ± 399.6 ng/ml, 142.0 ± 139.7 ng/ml, 88.4 ± 51.2 ng/ml, respectively). MMP-2 significantly decreased in both atorvastatin and control group on Day 3 and Day 14. But, decreases of MMP-2 on Day 3 and Day 14 from Day 1 were significantly greater in atorvastatin group (− 581.3 ± 237.3 ng/ml and − 447.7 ± 228.3 ng/ml, respectively) than in control group (− 321.3 ± 257.8 ng/ml and − 275.0 ± 179.4 ng/ml, respectively). MMP-9 significantly decreased in atorvastatin group on Day 3 and Day 14 (132.9 ± 85.5 ng/ml on Day1, 71.4 ± 48.6 ng/ml on Day 3, 53.0 ± 28.5 ng/ml on Day 14; p < 0.05), but did not change significantly in control group. MMP-3 did not significantly change in both groups. Conclusion: MMP-2 decreased with conventional HF treatment, but MMP-3 and -9 did not. Interestingly, early start of statin treatment significantly decreased both MMP-2 and -9, but not MMP-3 in acute HF. This is the first report demonstrating the effects of statin on MMPs in acute HF.

AbstractBackground:The aim of this study was to determine the serum levels of kisspeptin and ghrelin (GAH), as well as the relationship of these two peptides with each other in premature thelarche (PT) and premature adrenarche (PA) cases and to investigate the possibility of using these peptides as markers in the differentiation of puberty disorders.Methods:A PT group aged 1–8 years (n = 40), a PA group aged 1–9 years (n = 23, female/male = 20/3) and control groups consistent with each of the previous groups in terms of age and gender were created for the study. Kisspeptin and ghrelin levels were measured with ELISA methods from blood samples drawn while fasting in the morning.Results:When the PT group was compared with the controls, the plasma kisspeptin levels of the cases were significantly higher than the control group (165.47 ± 15.45 pmol/L, 96.82 ± 12.33 pmol/L, p = 0.005, respectively). Kisspeptin levels in the PA group did not show a difference with the control group (121.36 ± 17.99 pmol/L, 95.52 ± 11.54 pmol/L, p = 0.249, respectively). No significant difference could be found when GAH levels in the PT and PA groups were compared with controls. No significant correlation was found between kisspeptin and GAH levels in the PT and PA groups.Conclusions:Our results indicate that kisspeptin plays an important role in the PT, but GAH is not associated with puberty disorders.

 Background: Chronic kidney disease (CKD) includes irreversible destruction of nephrons leading to progressive decline in glomerular filtration rate. A preferential defect in Homocysteine disposal could hypothetically occur in CKD and subsequently lead to hyperhomocysteinemia. Understanding the status of Homocysteine and other parameters in CKD is useful in the management of the disease. Objective of the study is to estimate serum Homocysteine in CKD patients and its association with renal function and serum albumin in patients with CKD.Methods: The study design involves hospital based observational comparative study. The study was conducted in Department of Biochemistry in association with Department of Nephrology of Mahatma Gandhi Medical College and Hospital, Jaipur between May 2017 to June 2018. 100 diagnosed patients of CKD, visiting the Outpatient Department of Nephrology were enrolled as cases for the study. Patients having cardiovascular disease, Chronic liver disease, Age more than 60 years and pregnant females were excluded from study. The control group consists of 100 age and sex matched healthy individuals.Results: The mean serum creatinine levels of case and control group were 7.50±3.74 mg% and 0.83±0.22 mg% respectively. The mean of serum homocysteine levels of subject group was 27.35±12.52 µmol/L while the mean serum homocysteine levels of control group was 11.06±3.52 µmol/L. The serum homocysteine levels were significantly higher in the CKD patient group. The serum level of albumin in CKD patients and control group were 2.86±0.86 g/dl and 4.10±0.58 g/dl respectively. A positive correlation was found between serum creatinine and serum homocysteine levels. A negative correlation between serum homocysteine and serum albumin was found.Conclusions: Findings of the present study exhibit that serum homocysteine levels are elevated in CKD in comparison to healthy controls and it is positively correlated with serum creatinine level.

Background: The prevalence of vitamin D deficiency is increasing due to changes in lifestyle and dietary habits. The aim of this study was to compare the serum levels of 25-hydroxy vitamin D between patients with bronchial asthma and the healthy control group. Patients and Methods: In this case-control study, 45 patients with asthma and 45 healthy subjects were enrolled and the level of serum 25 (OH) vitamin D was measured in both groups. In addition, a welltrained observer assessed airway reversibility, peak flowmetry and spirometry in the participants. The data were statistically analyzed using t test, one-way analysis of variance (ANOVA), and chi-square test with Stata software (version 11). Results: The mean age (±SD) of participants were 49.06 ±16.43 and 46.13 ±16.10 years in case and control groups, respectively (P=.394). The prevalence of vitamin D deficiency was high in both groups (69% in case and 65.5% in control groups). The mean (±SD) serum 25 (OH) vitamin D was 16.24 (±14.98) ng/ml in case group and 17.70 (±16.07) ng/mL in control group (P=.657). We found a positive correlation between the levels of vitamin D and the amount of FEV1 (r=0.2). Conclusions: According to the present study, the mean serum levels of vitamin D differences were not statistically significant between asthmatic patients and control group. However, the results of this study showed a positive relationship between forced expiratory volumes in first second (FEV1) and vitamin D levels

Background and Aim: Obstructive urolithiasis is one of the major health problems in livestock animals, mainly in young calves. The present study was designed first to investigate the changes in the serum levels of Vitamins A and D in buffalo calves (Bubalus bubalis) with obstructive urolithiasis and second to investigate the efficacy of tube cystostomy technique in management of such condition. Materials and Methods: One hundred and forty-nine buffalo calves of variable ages ranged from 3 to 7 months with a history of retained urine were examined clinically and ultrasonographically. Then, they were subjected to surgical treatment using the tube cystostomy technique. The serum levels of Vitamins A and D were investigated in retained urine calves in addition to 10 clinically healthy calves of the same age used as a control group. Results: Based on clinical and ultrasonographic findings, the calves were diagnosed as obstructive urolithiasis with intact bladder (n=64 calves) or with bladder rupture (n=85 calves) with the peak incidence in winter months. Tube cystostomy was an efficient and quick surgical technique for the management of such condition and 95.3% of calves returned their normal urination within 7–14 days after surgery. Significant hypovitaminoses A and D were found between retained urine calves and control ones (p= 0.01 and 0.002, respectively). Conclusion: Hypovitaminoses A and D suggested predisposing obstructive urolithiasis in buffalo calves, but further clinical studies are recommended for more confirmation. Surgical treatment using tube cystostomy technique is recommended for the management of obstructive urolithiasis in buffalo calves.

Purpose: To investigate the effect of combination of vitamin D and anti-tuberculosis drugs on serum interleukin-1β (IL-1β), interferon-γ (IFN-γ) and helper T 17 (Th17) cell-associated cytokine levels for the treatment of spinal tuberculosis (TB). Methods: Ninety-two spinal TB patients were assigned without bias to two groups (46/group): study group (vitamin D combined with anti-TB drug group) and control group (anti-TB drug group). After treatment for 8 weeks, clinical effectiveness, adverse reactions, visual analog scale (VAS) score, spinal cord injury grade, and serum levels of IL-1β, IFN-γ, Th17, IL-10, TGF-β1, IL-17 and IL-23 were assayed with ELISA, and compared between groups. Results: Study group total effectiveness was significantly higher than that in the control group (95.65 % vs 80.43 %, p < 0.05). Before drug administration, VAS score, degree of spinal cord injury and serum levels of IL-1β, IFN-γ, IL-10, TGF-β1, IL-17 and IL-23 were comparable in the study and control patients (p > 0.05). However, post-treatment, these parameters significantly decreased in both groups (p < 0.05), but were markedly lower in study group patients, relative to controls (p < 0.05). Conclusion: The use of combined treatment of vitamin D and anti-TB drugs is an effective and safe way to alleviate inflammatory response and improve the immunity of spinal TB patients via the regulation of the levels of Th17 cell-related factors.

Abstract Pterygium is an inflammatory, vascular and degenerative disorder with unknown aetiology. The aim of this study was to evaluate the changes in neopterin levels, reflecting T-cell immunity, and the kynurenine pathway, the main degradation process of tryptophan, in pterygium. For this purpose, neopterin concentrations were measured in serum and tear samples by enzyme-linked immunosorbent assay (ELISA) in pterygium patients (n=31) and control group (n=32). Kynurenine (KYN) and tryptophan (TRP) serum levels were simultaneously determined by high-performance liquid chromatography (HPLC) for evaluation of the kynurenine pathway. Serum neopterin concentrations and kynurenine to tryptophan ratio (KYN/TRP) as an index of tryptophan breakdown were found increased in pterygium compared to controls (p<0.05). Although there was a 3-fold difference observed between serum and tear neopterin levels, no significant relationship was found. It can be concluded that neopterin may be used as a nonspecific biomarker that reflects immunological activity in pterygium and has clinical potential for evaluation of pterygium pathogenesis. These immune- or inflammatory-mediated changes were also supported by an increased KYN/TRP ratio in pterygium patients.

AbstractBackground:Anti-Müllerian hormone (AMH) is produced by granulosa cells surrounding follicles that have undergone recruitment from the primordial follicle pool but have not been selected for dominance (preantral and early antral follicles). In healthy girls, serum levels of AMH vary considerably between individuals. We aimed to evaluate the AMH level in girls with premature thelarche (PT) and central precocious puberty (CPP).Methods:Girls with CPP (n=21), PT (n=24) and a control prepubertal group (n=22) were included in the study.Results:AMH levels were significantly higher in the PT group than the prepubertal control group and similar to the CPP group. AMH levels in the CPP group were similar to the prepubertal control group. AMH levels showed a significant negative correlation with luteinizing hormone (LH), free testosterone and dehydroepiandrosterone sulphate (DHEAS) levels in the PT group. AMH levels were negatively correlated with height standard deviation score (HSDS), body mass index (BMI) SDS values and positively correlated with sex hormone binding globulin (SHBG) levels in the CPP group. These levels were positively correlated with SHBG levels in the control prepubertal group.Conclusions:Serum AMH levels in girls with PT was found to be higher than in prepubertal girls. AMH levels in the CPP group were not different compared with the PT and control groups.
