Conclusion:At present, the overall clinical research of Wumei pill shows an increasing tendency, mainly involving gastrointestinal disease.

Objective:To analyze the changes in plasma endothelin-1 (ET-1) concentrations in the patients with acute respiratory distress syndrome (ARDS).Methods:Fourteen patients with ARDS induced by trauma, 8 males and 6 females, aged 19-80 yr, were studied. The severity of ARDS was graded according to the Berlin definition of ARDS after admission to intensive care unit (ICU). Venous blood samples were obtained on 1st, 3rd and 5th days after admission to ICU, the plasma ET-1 concentrations were measured by radioimmunoassay, the pulmonary vascular permeability index (PVPI) was determined by PiCCO technique, and multiple organ dysfunction (MOD) score and lung injury score (LIS) were assessed. Spearman correlation of plasma ET-1 concentrations with MOD score, LIS and PVPI was analyzed.Results:MOD score, LIS, PVPI and plasma ET-1 concentrations were significantly decreased in mild ARDS patients ( n=5) as compared with moderate ARDS patients ( n=9, P<0.05). The plasma ET-1 concentration was positively correlated with MOD score, LIS and PVPI ( r=0.69, 0.76, 0.62, P<0.001). Conclusions:Plasma ET-1 concentrations can reflect the pulmonary vascular permeability and even the severity of the disease in the early stage of ARDS, so it is necessary to carry out dynamic monitoring in the patients.

Objective:To evaluate the role of aryl hydrocarbon receptor (AhR) in the down-regulation of Clara cell secretory protein (CCSP) expression during endotoxin-induced lung injury in rats.Methods:Twenty-four clean-grade healthy male Sprague-Dawley rats, aged 8 weeks, weighing 200-250 g, were divided into 4 groups ( n=6 each) using a random number table method: normal control group (group C), acute lung injury (ALI) group, ALI+ AhR antagonist group, and ALI+ vehicle group. Lipopolysaccharide(LPS) 1 mg/kg was intratracheally instilled to develop the model of lung injury, while the equal volume of normal saline was given instead in group C. At 2 h before LPS injection, AhR antagonist 6, 2′, 4′-trimethoxyflavone solution 5 mg/kg (diluted to 1 ml in dimethyl sulfoxide solution) was intraperitoneally injected in ALI+ AhR antagonist group, while dimethyl sulfoxide solution 1 ml was given in ALI+ vehicle group. The rats were sacrificed under anesthesia at 48 h after LPS administration. The left lung was lavaged and the broncho-alveolar lavage fluid (BALF) was collected for determination of the concentrations of CCSP by enzyme-linked immunosorbent assay, and the expression of CCSP in the bronchial epithelium in right lung tissues was determined by immunohistochemistry. Results:Compared with group C, the expression of CCSP in the bronchial epithelium was significantly down-regulated, and the concentrations of CCSP in BALF were decreased in the other three groups ( P<0.05 or 0.01). Compared with ALI group and ALI+ vehicle group, the histopathological injury was significantly reduced, the expression of CCSP in the bronchial epithelium was up-regulated, and the concentrations of CCSP in BALF were increased in ALI+ AhR antagonist group ( P<0.01). Conclusions:AhR partially mediates the down-regulation of CCSP expression during endotoxin-induced lung injury in rats.

Objective:To explore the risk factors of intracranial aneurysm interventional embolization for subarachnoid hemorrhage (SAH) perioperative infection.Methods:A retrospective analysis of the clinical data of 236 SAH patients who underwent aneurysm interventional embolization in the Department of Neurosurgery, Huangshan Shoukang Hospital from May 2018 to December 2019, and statistics of the surgical treatment effects and postoperative conditions of all patients, according to the perioperative Infective status in the early stage, the patients were divided into infected group ( n=44) and non-infected group ( n=192) according to the perioperative infection, and the clinical indicators of the patients were recorded, including age, gender, history of drinking, smoking history, history of diabetes, and whether there was any temporary blockade during the operation, aneurysm location, triacylglycerol, lipoprotein type, CT-Fisher classification, history of hypertension, aneurysm diameter, number, albumin, Hunt-Hess classification, Glasgow coma score (GCS) at admission, number of punctures. Measurement data were expressed as the mean ± standard deviation ( Mean± SD), comparison between groups was by t-test; count data comparison between groups was by Chi-square test. Logistic regression was used to analyze the risk factors of infection in SAH patients during perioperative period. Results:The treatment success rate of all SAH patients was 100%; the results of univariate analysis showed that the history of hypertension, aneurysm diameter, number, albumin, Hunt-Hess classification, GCS score at admission, and number of punctures were compared between infected group and non-infected group, the difference was statistically significant ( P<0.05); the results of multivariate Logistic regression analysis showed that history of hypertension, aneurysm diameter ≥8 mm, a large number of aneurysms, albumin ≤35.12 g/L, Hunt-Hess classification Grade Ⅲ to Ⅳ, GCS score> 5 points at admission, and number of punctures>2 times were risk factors for perioperative infection in SAH treated by interventional embolization of intracranial aneurysm; the total score of all factors in the nomogram prediction model was 314.84 points, the corresponding value was 14.96% of the perioperative infection rate of intracranial aneurysm interventional embolization for SAH. Conclusions:Interventional embolization of intracranial aneurysm for SAH can achieve good clinical results. However, history of hypertension, aneurysm diameter ≥ 8 mm, a large number of aneurysms, albumin ≤ 35.12 g/L, Hunt-Hess grade Ⅲ to Ⅳ, GCS score > 5 points at admission, number of punctures> 2 times are all independent risk factors leading to perioperative infection in patients, and clinical attention should be paid to and actively prevented.

Objective To evaluate the application value of the blastocysts derived from non-pronucleus (0PN) zygotes by the good quality blastocyst formation rate and the clinical outcomes of frozen-thawed blastocyst transfers. Methods The good quality blastocyst formation rate derived from 0PN zygotes was compared with that derived from2 pronucleus(2PN)zygotes in in vitro fertilization(IVF)or intracytoplasmic sperm injection (ICSI) cycles from January 2015 to December 2016. In addition, the clinical pregnancy, embryo implantation and live birth rates of frozen-thawed blastocyst transfers with blastocysts derived from 0PN and 2PN zygotes were analyzed on corresponding dates. Results (1)In IVF cycles, the high quality blastocysts formation rate of 2PN embryos was significantly higher than that of 0PN (46.64% versus 42.42%, P<0.01). In ICSI cycles, the high quality blastocysts formation rate of 2PN embryos was markedly higher than that of 0PN(41.96% versus 21.73%, P<0.01).(2)In frozen-thawed embryo transfer cycles for IVF, the clinical pregnancy, implantation and live birth rates of D5 0PN blastocysts were significantly higher than those of D6 2PN(52.64% versus 46.78%, 49.91% versus 41.20%, 46.54% versus 39.56%, all P<0.05), however, the abortion and newborn abnormal rates of D5 0PN blastocysts were lower than those of D6 2PN blastocysts(17.37% versus 23.36%, 1.31% versus 4.21%, both P<0.05); the clinical pregnancy, implantation and livebirth rates of D5 2PN blastocysts were significantly higher than those of D5 0PN(59.73% versus 52.64%, 55.95% versus 49.91%, 53.03% versus 46.54%, all P<0.05), but newborn abnormal rate was a little higher than that of D5 0PN(3.90% versus 1.31%, P<0.05);the clinical pregnancy, implantation and live birth rates of D5 2PN blastocysts were significantly higher than those of D6 2PN(59.73% versus 46.78%, 55.95% versus 41.20%, 53.03% versus 39.56%, all P<0.05), and the abortion rate of D5 2PN blastocysts was lower than that of D6 2PN blastocysts(18.23% versus 23.36%, P<0.05). Conclusions Although the blastocysts derived from 0PN could be transffered, the blastocysts derived from 2PN zygotes are preferred in all cycles. In IVF cycles, the good quality blastocysts derived from 2PN or 0PN zygotes will be transferred.

BACKGROUND:Jumonji domain-containing histone demethylase (JMJD) can promote osteoblast differentiation, and estrogen-related receptor alpha (ERRα) can promote osteoblast differentiation and increase bone formation. However, little is reported on the association between postmenopausal osteoporosis andJMJD and ERRα. OBJECTIVE: To study the changes in the JMJD2 family expression in patients with postmenopausal osteoporosis. METHODS: Postmenopausal patients with osteoarthritis of the hip scheduled for total hip arthroplasty, aged 50-70 years, were enroled, including 10 postmenopausal osteoporosis patients (experimental group) and 10 patients with no postmenopausal osteoporosis (control group). During the arthroplasty, the cancelous bone specimens from the femoral head were colected. Then, immunohistochemistry and western blot assay were used to detect expression of histone demethylase (JMJD2A, JMJD2B), histone methylation (H3K9me3, H3K36me3) and ERRα. RESULTS AND CONCLUSION:In the experimental group, the expressions of JMJD2A, JMJD2B and ERRαwere from weakly positive to positive; these expressions were significantly lower in the experimental group than the control group (P < 0.05). The expressions of H3K9me3 and H3K36me3 were significantly higher in the experimental group than the control group (P < 0.05). These findings indicate that the expression of JMJD2A and JMJD2B is consistent with the expression of ERRα in the patients with postmenopausal osteoporosis, and JMJD is likely to serve as an antagonistic enzyme of osteoporosis.

BACKGROUND:Estrogen signaling pathway for interaction between aromatase and estrogen-related receptor may exist in bone marrow mesenchymal stem cel s, which is used for regulating biological activity of bone marrow mesenchymal stem cel s. OBJECTIVE:To observe the expression of aromatase and estrogen-related receptors in adult bone marrow mesenchymal stem cel s during osteogenic differentiation. METHODS:Bone marrow mesenchymal stem cel s were respectively cultured in low-glucose DMEM medium (control group) and osteogenic induction medium (induction group). Cel proliferation and calcium deposition were determined by MTT assay and alizarin red staining, respectively. The expression of aromatase, estrogen receptorα, estrogen receptorβ, and estrogen-related receptorαduring osteogenic differentiation were determined by real-time PCR and western blot analysis. Estradiol levels in supernatants and lysates were detected by ELISA method. RESULTS AND CONCLUSION:In the induction group, the proliferation ability of bone marrow mesenchymal stem cel s was the strongest at 72 hours of culture;while there were a great amount of calcium nodules formed at 21 days of culture. Results from PCR and western blot assay showed that the expression of aromatase and estrogen receptorαwas improved in the induction group, but the expression of estrogen-related receptorαwas inhibited. There was no difference in the expression of estrogen receptorβbetween the two groups. ELISA results indicated that the level of estradiol in the supernatant of induction group was the highest. These findings indicate that aromatase, estrogen receptorα, estrogen receptorβand estrogen-related receptorαare al involved in osteogenesis of bone marrow mesenchymal stem cel s. Moreover, estradiol can be synthesized and secreted in bone marrow mesenchymal stem cel s, and most likely, promote the osteogenic differentiation of bone marrow mesenchymal stem cel s by related receptor pathway.

OBJECTIVE:To investigate the paracrine effects of bone marrow mesenchymal stem cells on osteoblast biological function. METHODS:Bone marrow mesenchymal stem cells were isolated using standard Ficol-Paquedensity gradient centrifugation. Mesenchymal stem cellconditioned medium was prepared to cultivate osteoblasts, MG63. Proliferation of MG63 cells was analyzed by cellcounting kit-8. Migration of MG63 cells was analyzed by cellscratch method. Alkaline phosphatase activity of MG63 cells was analyzed by microplate test kit. Real-time PCR was performed to evaluate osteoblast differentiation markers, alkaline phosphatase, col agen type I and osteocalcin. Alizarin red staining was performed to evaluate osteoblast mineralization. RESULTS AND CONCLUSION:The cells were strongly positive for CD44, CD73 and CD90, but negative for CD34. MG63 cells cultured in the conditioned medium showed better proliferation and migration than those cultured in the Dulbecco’s modified Eagle’s medium. The activity and mRNA expression of alkaline phosphatase were much higher after induction of 4, 7 days (P<0.01). There was no significant difference in expression of col agen type I and osteocalcin after induction of 4 days, but they were significantly higher than those in the control group after induction of 7 days (P<0.05). Alizarin red staining showed that the number of calcium nodules was increased and the mineral apposition was enhanced after induction of 21 days with the conditioned medium. These findings suggest that the paracrine substance of bone marrow mesenchymal stem cells can significantly promote osteoblast proliferation, migration, differentiation and mineralization.

OBJECTIVE: To evaluate the therapeutic results of endoscopic orbital decompression for thyroid-associated ophthalmopathy. METHOD: The records of nine patients (twelve orbits) received endoscopic orbital decompression for thyroid-associated ophthalmopathy were analyzed for changes in visual acuity, intraocular pressure, proptosis, corneal ulceration and movement. The follow-ups ranged from two months to thirty-six months. RESULT: Twelve orbits (100%) had improvement in visual acuity (range 0.1-0.7). Ten orbits (83.3%) decreased in intraocular pressure (range 0.2-21.4 mm Hg). Eight orbits (66.70%) decreased in proptosis (one-five mm). The orbit with corneal ulcer was healed after decompression. Diplopia was cured in one of four patients. CONCLUSION Endoscopic orbital decompression is a safe and effective procedure for the treatment of thyroid-associated ophthalmopathy.
