The content of Schisandrin was determined by HPLC. Welch Materials C18 column (250 mm×4.6 mm, 5 μm) with mobile phase of methanol-water (70∶30) was used. The detective wavelength was 250 nm. Results The TLC for identification was simple and special. Schisandrin showed a good linear relationship in 0.222-0.222 0 μg, r=0.999 9. The average recovery was 98.96%, and RSD was 0.74%. Conclusion The method can accurately determine the content of Schisandrin in Yuling Tea. It can be used for quality control of the preparation.

AIM To observe the effects of Wuwei Wentong Chubi Capsules (Cinnamomi Ramulus,Poria,Epimedii Folium,etc.) on autophagy proteins of Beclin-1 and LC3-Ⅱ in adjuvant-induced arthritis rats and to explore the possible mechanism of action.METHODS Sixty SD rats were randomized into six groups:normal group,model group,Wuwei Wentong Chubi Capsules (0.8,1.6,3.2 g/kg) groups and tripterygium glycosides (TPT,40 mg/kg) group.In addition to the normal group,adjuvant arthritis (AA) was induced with Freund's complete adjuvant.From the 2th day after injection of FCA,Wuwei Wentong Chubi Capsules with different doses and TPT were given by gavage once a day for 12 days.At the end of the experiment,ankle-joint samples were taken to examine the degree of AA by HE.Beclin-1 and LC3-Ⅱ mRNA were determined by real-time fluorescent quantitative PCR.Meanwhile,the protein expression levels of Beclin-1 and LC3-Ⅱ were determined by immunofluorescence histochemical staining and Western blot.RESULTS As compared with the model group,Wuwei Wentong Chubi Capsules (1.60,3.20 g/kg) not only significantly reduced histopathological injuries,but also effectively up-regulated mRNA and protein expressions of Beclin-1 and LC3-Ⅱ.CONCLUSION Wuwei Wentong Chubi Capsules has a therapeutic action on AA in rats,which might be partly associated with promoting autophagy,decreasing excessive proliferation of synovial cells,leading to the reduction of damage to articular cartilage.

Objective To survey the prevalence of undemutrition in elderly leprosy patients and explore the feasibility of nutritional assessment. Methods The nutrition status of 60 elderly patients with advanced leprosy was analyzed using Subjective Global Assessment (SGA) and objective methods. Results Undemutrition was determined in 22 patients (36. 6% ), including 5 patients ( 8. 3% ) were at a status of severe undernutrition. Kap-pa value of SGA and the objective items were 0. 619, 0. 571, 0. 476, 0. 454, and 0. 419 for triceps skin-fold thickness (TSF), pre-albumin (PALB), mid arm muscle circumference (MAMC), hemoglobin (Hb), and ser-um albumin, respectively. Gender, admission duration, type of leprosy, or disability grade was not correlated to all nutritional parameters except body height and cholesteroL Age and extent of ulceration were significantly correlated with some parameters such as BMI, TSF, lib, ALB, and PALB ( P < O. 01 ). Sensitivity and specificity of SGA on objective parameters screened were different. TSF and ulcer had the hrgest impacts on SGA. Conclusions The prevalence of undernutrition is not high in elderly leprosy patients. Any single objective parameter is not feasible for the assessment of nutrition status in these patients. A comprehensive method using SGA is preferred.

Objective To explore the changes in plasma soluble fibrin monomer complex(SFMC)levels at different gestation periods of healthy women in Yibin area of Sichuan and establish reference ranges for SFMC at different gestational stages.Methods A total of 377 healthy pregnant women and 120 health examinees who received antenatal examination in Yibin Maternal and Child Health Care Hospital from May 2021 to January 2022 were enrolled in this study and grouped into the early pregnant group,the second trimester group,the late pregnant group and control group.The plasma SFMC and D-dimer(D-D)of all groups were detected using the latex immunoturbidimetry and reference ranges of SFMC were established for each group.Meanwhile,the correlation between SFMC and D-D was analyzed at the same time.Results The reference ranges of SFMC in the control group,the early pregnant group,the second trimester group and the late pregnant group were＜7.3μg/ml,＜18.4μg/ml,＜20.4μg/ml and＜58.5μg/ml,respectively.The difference between groups was statistically significant(F=55.989,P＜0.001),and the plasma SFMC levels showed an upward trend as pregnancy progressed.The SFMC level in plasma was positively correlated with the D-D level(r2=0.468 8).Conclusion The plasma SFMC levels in pregnant women significantly increased with the progression of pregnancy,and the reference range of the normal population cannot meet the risk assessment of venous thrombosis in pregnant women.This study preliminary established reference ranges for plasma SFMC in women at different gestation periods,which has important clinical significance for monitoring and preventing venous thromboembolism in pregnant population.

AIM: To investigate the effect of Qiteng Xiaozhuo granule on inflammation indexes in rats with chronic glomerulonephritis (CGN) through miR-339-5p. METHODS: CGN model was established by adriamycin (ADR) injection into tail vein of rats. Qiteng Xiaozhu granules (21.6, 10.8, 5.4 g/kg) of different doses were intragastric-fed for 30 days. Pathological changes in kidney tissues of CGN rats were observed by HE staining and electron microscopy. The contents of IL-1β, IL-6, IL-10 and TNF-α in serum and kidney tissue of CGN rats were detected by qRT-PCR, ELISA and Western blot. Relative expressions of miR-339-5p, Syk and p-Syk proteins were detected by Western blot, the relative expressions of miR-339-5p mRNA and Syk mRNA were detected by qRT-PCR. RESULTS: There were thickening of basement membrane and glomerular atrophy in the model group. Compared with the normal group, the expression of miR-339-5p and IL-10 in the model group was significantly down-regulated, while the expression of IL-1β, IL-6, TNF-α and Syk was significantly up-regulated. Qiteng Xiaozhuo granule group could significantly reduce the protein and mRNA expression levels of IL-1β, IL-6, TNF-α, Syk in kidney tissue.CONCLUSION: Qiteng Xiaozhuo granule may down-regulate the expression of inflammatory factors through miR-339-5p in the treatment of inflammatory symptoms in CGN rats.

OBJECTIVE: To investigate the effect of miR-324-5p on the proliferation of rat glomerular mesangial (HBZY-1) cells and the role of Syk/Ras/c-fos signaling pathway in mediating this effect. METHODS: HBZY-1 cells cultured in vitro were transiently transfected with miR-324-5p mimics or miR-324-5p-mimics-NC followed by treatment with lipopolysaccharide (LPS). MTT assay was used to detect the proliferation activity of HBZY-1 cells, and RT-qPCR was used to detect the expressions of miR-324-5p and the mRNA expressions of Syk, Ras, MEK1/2, ERK1/2 and c-fos mRNA. The protein expressions of p-Syk, Ras, p-MEK1/2, p-ERK1/2 and c-Fos were detected by Western blotting and immunofluorescence assay. RESULTS: MTT assay showed that exposure to LPS significantly enhanced the proliferative activity of HBZY-1 cells. Compared with the cells treated with LPS and LPS + mimics NC, the cells transfected with miR-324-5p mimics prior to LPS exposure exhibited significantly lowered proliferative activity. Transfection with miR-324-5p mimics significantly lowered the mRNA expressions of Syk, Ras, MEK1/2, ERK1/2 and c-fos and the protein expressions of p-Syk, Ras, MEK1/2, ERK1/2 and c-Fos ( CONCLUSIONS miR-324-5p can inhibit the proliferation of rat chronic glomerulonephritis cells induced by LPS by inhibiting Syk/Ras/c-fos signaling pathway and may potentially serve as a diagnostic indicator and a therapeutic target for chronic glomerulonephritis.

OBJECTIVESince 1986, the reference of birth weight for gestational age has not been updated. The aim of this study was to set up Chinese neonatal network to investigate the current situation of birth weight in China, especially preterm birth weight, to develop the new reference for birth weight for gestational age and birth weight curve.

METHODA nationwide neonatology network was established in China. This survey was carried out in 63 hospitals of 23 provinces, municipalities and autonomous regions. We continuously collected the information of live births in participating hospitals during the study period of 2011-2014. Data describing birth weight and gestational age were collected prospectively. Newborn's birth weight was measured by electronic scale within 2 hours after birth when baby was undressed. The evaluation of gestational age was based on the combination of mother's last menstrual period, ultrasound in first trimester and gestational age estimation by gestational age scoring system.

STATISTICAL ANALYSISthe growth curve was drawn by using LMSP method, which was conducted in GAMLSS 1.9-4 software package in R software 2.11.1.

RESULTA total of 159 334 newborn infants were enrolled in this study. There were 84 447 male and 74 907 female. The mean birth weight was (3 232 ± 555) g, the mean birth weight of male newborn was (3 271 ± 576) g, the mean weight of female newborn was (3 188 ± 528) g. The test of the variables' distribution suggested that the distribution of gestational age and birth weight did not fit the normal distribution, the optimal distribution for them was BCT distribution. The Q-Q plot test and worm plot test suggested that this curve fitted the distribution optimally. The male and female neonatal birth weight curve was developed using the same method.

CONCLUSIONUsing GAMLSS method to establish nationwide neonatal birth weight curve, and the first time to update the birth weight reference in recent 28 years.
