Metabolomics-based comparative analysis of the effects of host and environment on Viscum coloratum metabolites and antioxidative activities / 药物分析学报

Viscum coloratum(Komn.)Nakai is a well-known medicinal hemiparasite widely distributed in Asia.The synthesis and accumulation of its metabolites are affected by both environmental factors and the host plants,while the latter of which is usually overlooked.The purpose of this study was to comprehensively evaluate the effects of host and habitat on the metabolites in V.coloratum through multiple chemical and biological approaches.The metabolite profile of V.coloratum harvested from three different host plants in two habitats were determined by multiple chemical methods including high-performance liquid chromatography-ultraviolet(HPLC-UV),gas chromatography-flame ionization detector(GC-FID)and ultra-performance liquid chromatography quadrupole time of flight mass spectrometry(UPLC-QTOF/MS).The differences in antioxidant efficacy of V.coloratum were determined based on multiple in vitro models.The multivariate statistical analysis and data fusion strategy were applied to analyze the dif-ferences in metabolite profile and antioxidant activity of V.coloratum.Results indicated that the metabolite profile obtained by various chemical approaches was simultaneously affected by host and environment factors,and the environment plays a key role.Meanwhile,three main differential metab-olites between two environment groups were identified.The results of antioxidant assay indicated that the environment has greater effects on the biological activity of V.coloratum than the host.Therefore,we conclude that the integration of various chemical and biological approaches combined with multivariate statistical and data fusion analysis,which can determine the influences of host plant and habitat on the metabolites,is a powerful strategy to control the quality of semi-parasitic herbal medicine.

Structural Design and Finite Element Analysis of New Type Posterior Integral Glaucoma Valve / 中国医疗器械杂志

The treatment of refractory Glaucoma is a difficult problem in clinical ophthalmology. For refractory glaucoma patients with hyphema, shallow anterior chamber, anterior conglutination of peripheral chamber angle, corneal endothelium dystrophy or decompensated, at present, there is no effective treatment. In order to solve this problem, a new type posterior integral glaucoma valve with IOP control device was designed using medical titanium alloy, and the valve model was established by Abaqus software, and the stiffness and preload of the valve were analyzed by finite element method. The results showed that the opening and closing of the valve were controlled automatically by the pressure difference between the front and back of the valve, and the opening and flow rate of the valve increase dynamically with the increase of intraocular pressure, and finally reached the set ideal IOP value of steady state.

Comparative effect of ciprofloxacin and moxifloxacin on the modulation of bile acid profiles and gut microbiota in rats

Abstract Fluoroquinolones are an important class of antimicrobial agents to manage infectious diseases. However, knowledge about how host bile acids are modified by fluoroquinolones is limited. We investigated and compared the impact of fluoroquinolones on circulating bile acid profiles and gut microbiota from in vivo studies. We administered ciprofloxacin (100 mg/kg/day) or moxifloxacin (40 mg/kg/day) orally to male Wistar rats for seven days. Fifteen bile acids (BAs) from the serum and large intestine were quantified by HPLC-MS/MS. The diversity of gut microbiota after ciprofloxacin and moxifloxacin treatment was analyzed using high-throughput, next-generation sequencing technology. The two fluoroquinolone-treated groups had different BA profiles. Ciprofloxacin significantly reduced the hydrophobicity index of the BA pool, reduced secondary BAs, and increased taurine-conjugated primary BAs in both the serum and large intestine as compared with moxifloxacin. Besides, ciprofloxacin treatment altered intestinal microbiota with a remarkable increase in Firmicutes to Bacteroidetes ratio, while moxifloxacin exerted no effect. What we found suggests that different fluoroquinolones have a distinct effect on the host BAs metabolism and intestinal bacteria, and therefore provide guidance on the selection of fluoroquinolones to treat infectious diseases.

Cryptorchid testicular torsion in children: characteristics and treatment outcomes / 亚洲男科学杂志(英文版)

This study aimed to review and compare the characteristics and treatment outcomes of cryptorchid testicular torsion in pre- and postpubertal children. We reviewed the clinical data of 22 patients with testicular torsion complicated by cryptorchidism who were treated between January 2010 and December 2019. Patients were categorized into prepubertal (1 month to 9 years; n = 12) and postpubertal groups (10-16 years; n = 10). The age at presentation, clinical presentations, physical examination, and operation outcomes were assessed. The common clinical presentations in both groups were inguinal pain and a tender inguinal mass. Patients in the prepubertal group were significantly more likely to present with restlessness (33.3%) than those in the postpubertal group (0%; P = 0.044). After detorsion, testicular blood flow recovered during surgery in 25.0% of the prepubertal and 80.0% of the postpubertal patients (P = 0.010). Orchiectomy was required in 50.0% of the prepubertal and 20.0% of the postpubertal patients (P = 0.145). Of the 22 patients with follow-up data, the rates of testicular salvage were significantly different, at 16.7% in the prepubertal patients and 60.0% in the postpubertal patients (P = 0.035). Cryptorchid testicular torsion has various manifestations. Although an empty hemiscrotum and a painful groin mass were common in both groups, restlessness was more prevalent in the prepubertal patients during early testicular torsion onset than that in the postpubertal patients. Notably, the testicular salvage rate was significantly lower in the prepubertal patients than that in the postpubertal patients.

Application and efficacy of reconstructing forked corpus spongiosum in distal/midshaft hypospadias repair / 亚洲男科学杂志(英文版)

We reviewed our experience in reconstructing forked corpus spongiosum (FCS) in distal/midshaft hypospadias repair and analyzed the efficacy of this surgical technique. From August 2013 to December 2018, 137 consecutive cases of distal/midshaft hypospadias operated by the same surgeon in Urology Department, Children's Hospital of Fudan University (Shanghai, China), were retrospectively analyzed. Sixty-four patients who underwent routine tubularized incised plate (TIP) or onlay island flap (ONLAY) surgery were included in the nonreconstructing group, and 73 patients who underwent reconstructing FCS during TIP or ONLAY surgery were included as the reconstructing group. Thirty-eight cases underwent TIP, and 26 underwent ONLAY in the nonreconstructing group, with a median follow-up of 44 (range: 30-70) months. Twenty-seven cases underwent TIP, and 46 underwent ONLAY in the reconstructing group, with a median follow-up of 15 (range: 6-27) months. In the nonreconstructing/reconstructing groups, the mean age at the time of surgery was 37.55 (standard deviation [s.d.]: 29.65)/35.23 (s.d.: 31.27) months, the mean operation duration was 91.95 (s.d.: 12.17)/93.84 (s.d.: 14.91) min, the mean neourethral length was 1.88 (s.d.: 0.53)/1.94 (s.d.: 0.53) cm, and the mean glans width was 11.83 (s.d.: 1.32)/11.56 (s.d.: 1.83) mm. Twelve (18.8%)/5 (6.8%) postoperative complications occurred in the nonreconstructing/reconstructing groups. These included fistula (5/2), glans dehiscence (3/0), diverticulum (1/2), residual chordee (3/0), and meatus stenosis (0/1) in each group. There was a significant difference in the overall rate of complications (P= 0.035). These results indicate that the technique of reconstructing FCS provides excellent outcomes with fewer complications in distal/midshaft hypospadias repair.

Trichostatin A inhibits the proliferation of gastric cancer cells through the promotion of autophagy via p-Akt/p-mTOR pathway / 医学研究生学报

Objective　Trihostatin A (TSA) is a histone deacetylase inhibitor of oxime salts, which has certain anti-tumor activity. This article mainly investigates the molecular mechanism of TSA inhibiting cell proliferation through p-AKT/p-mTOR pathway in gastric cancer cells.　Methods　Gastric cancer cell line-SGC-7901 were treated with TSA of different concentrations, and the inhibition rate of TSA on the cells was detected by MTT assay. The cells were divided into control group (without any treatment), TSA-treated group (200ng/ml TSA), p-AKT covering group (200 ng/mL TSA+8 μg/mL SC79) and autophagy inhibition group (5 mmol/mL 3-methyladenine+200 ng/mL TSA). The protein expression distribution of Lc3 in control and TSA group were detected by cell immunofluorescence staining. The relative expression levels of p-AKT, p-mTOR and autophagy related proteins Lc3 and P62 in control group, TSA group and p-AKT covering group were detected by Western blot. The proliferation of cells in control group, TSA group, p-AKT covering group and autophagy inhibition group were measured by EdU and cell count assay.　Results　After 24h of treatment, Lc3 in TSA group formed a large number of granular aggregates in the cytoplasm, and the fluorescence distribution changed from the initial diffuse to dense. The TSA group showed a significant reduction in green fluorescence compared with the control group in the EdU experiment. The expression levels of p-AKT in the control group, TSA group and the autophagy inhibition group were 1.78±0.19, 0.92±0.03 and 1.71±0.19, respectively, and Lc3 were 0.21±0.01, 0.79±0.06 and 0.55±0.10, respectively. Compared with the control group, the relative expression level of p-AKT in the TSA group all decreased, while the expression level of Lc3 increased (P <0.05). p-mTOR in the three groups was 0.80±0.16, 0.45±0.04 and 0.98±0.16, respectively. Compared with the control group, the relative expression level of p-mTOR in the TSA group all decreased (P <0.05). P62 in the three groups was 1.17±0.15, 0.48±0.08 and 0.77±0.10, respectively. Compared with the control group, the relative expression level of P62 in the TSA group all decreased (P<0.05). Compared with the TSA group, p-AKT, p-mTOR and P62 expression in the p-AKT covering group increased (P<0.05), while Lc3 expression decreased (P<0.05). Compared with the control group, the inhibition effect of cell growth curve was the most obvious in the TSA group, while the cell growth curve of p-AKT covering group and autophagy inhibition group showed a partial recovery compared with the TSA group.　Conclusion　TSA can promote autophagy by inhibiting p-AKt/p-mTOR pathway, thus inhibiting the proliferation of gastric cancer cells.

Knockout of glutathione peroxidase 5 down-regulates the piRNAs in the caput epididymidis of aged mice / 亚洲男科学杂志(英文版)

The mammalian epididymis not only plays a fundamental role in the maturation of spermatozoa, but also provides protection against various stressors. The foremost among these is the threat posed by oxidative stress, which arises from an imbalance in reactive oxygen species and can elicit damage to cellular lipids, proteins, and nucleic acids. In mice, the risk of oxidative damage to spermatozoa is mitigated through the expression and secretion of glutathione peroxidase 5 (GPX5) as a major luminal scavenger in the proximal caput epididymidal segment. Accordingly, the loss of GPX5-mediated protection leads to impaired DNA integrity in the spermatozoa of aged Gpx5

Theory Analysis on Absorption of Exogenous Substances in Traditional Chinese Medicine / 中国实验方剂学杂志

The safety of traditional Chinese medicine is affected by many factors, and the influence of exogenous harmful substances has been concerned and become a hot spot in recent years, especially heavy metals, pesticide residues and some other harmful substances. In order to explore the effects of non-soil and non-pesticide treatment on residues of these two harmful substances, the heavy metals and agricultural residues of Lilii Bulbus were detected, and the correlation of the data was analyzed. In this experiment, heavy metals and pesticide residues of Scrophulariae Radix were detected, and correlation analysis was conducted for their data. The mechanism of transport phase was interpreted with statistical moment similarity tool of total fingerprint by supramolecular chemistry theory. A large number of experimental data in this paper showed that heavy metals and pesticide contents in Lilii Bulbus basaltifolia had a positive correlation, which was closely related to supramolecular phenomena. Moreover, the similarity of fingerprints between Lilii Bulbus and Scrophulariae Radix suggested that Lilii Bulbus and Scrophulariae Radixa had a high selectivity in absorption of agricultural residues, which proved that the absorption of pesticides in Lilii Bulbus and Scrophulariae Radix from different habitats had the function of supramolecular imprinting template. It was considered that medicinal plant was a giant complex supramolecule with various levels of " imprinted template" . Heavy metals and agricultural residues were also involved in plant growth, forming an " imprinted template" for the formation of supramolecules between agricultural residues and heavy metals. After heavy metals and agricultural residues formed supramolecules, their liposolubility and permeability changed in varying degrees, and their transport in medicinal plants was promoted. Finally, the heavy metal supramolecules of pesticides were absorbed, distributed, aggregated and accumulated in plants. The purpose of the study was to reveal the mechanism of heavy metal and pesticide supramolecule transport, provide a new direction for the treatment of heavy metals and pesticide residues, and ensure the safety of traditional Chinese medicine.

Objective To explore the association between unhealthy diets and depression in early pregnancy. Methods 7 976 women in early pregnancy were recruited and analyzed in this study from the Chinese Pregnant Women Cohort Study (CPWCS) from July 25th, 2017 to July 24th, 2018. Differences of baseline characteristics between the two groups were conducted by a chi-square test. The qualitative food frequency questionnaire and the edinburgh postnatal depression scale were used to assess depression status and food intake frequency during the first trimester respectively. Log-binomial regression was used to analyze the relationship between unhealthy diets and depression in early pregnancy. Prevalence ratio (PR) and its 95% confidence interval (95% CI) were calculated. Results Eating regularly (PR=0.45, 95% CI:0.38-0.54，P<0.001) and eating breakfast frequently (PR=0.80, 95% CI:0.72-0.90, P<0.001) were related to the low incidence of depression while frequent consumption of fried food (PR=1.25, 95% CI:1.03-1.53, P=0.027), Western-style fast food (PR=1.36, 95% CI:1.06-1.74, P=0.015) and puffed food (PR=1.37, 95% CI:1.11-1.70, P=0.003) as well as drinking sugar-sweetened beverage (PR=1.37, 95% CI:1.17-1.61, P<0.001),wine (PR=1.60, 95% CI:1.26-2.01, P<0.001) and liqueur (PR=1.26, 95% CI:1.00-1.59, P=0.047) were linked with the high incidence of depression. Conclusions There might be an association between unhealthy diets and depression in early pregnancy. Pregnant women should take the initiative to better understand what are healthy diets and reduce the frequency of unhealthy diets consumption to decrease the incidence of depression during pregnancy.

Mechanism of Total Flavonoids of Ampelopsis Grossedentata in Inhibiting Liver Cancer by PI3K/Akt/p53 Pathway / 中国实验方剂学杂志

Objective: To study inhibitory effect of total flavonoids from Ampelopsis grossedentata (TF) on transplanted tumors of human hepatocellular carcinoma in nude mice, and predict that its mechanism may be related to relevant factors regulating phosphatidylinositol 3 kinase (PI3K)/protein kinases B(Akt)/p53 pathway in apoptosis. Method: The nude mice transplanted BEL-7404 hepatoma model was established and divided into model group, 5-fluorouracil (5-FU) group (1.0 g·L-1) and TF (30, 15, 7.5 g·L-1) groups. Nude mice were put to death after two weeks of administration. The tumor tissues were excised, and tumor inhibition rate (IR) and relative tumor proliferation rate (T/C) were calculated. Reverse transcription PCR(RT-PCR) was used to detect PI3K, Akt1, p53 gene(p53), Caspase-3, B cell lymphoma/lewkmia-2 (Bcl-2), Bcl-2 associated X protein (Bax) mRNA expressions, immunohistochemical method was used to detect expressions of relevant proteins PI3K, Akt1, p53, Caspase-3, Bcl-2, Bax. Result: The establishment of xenograft tumor in mice showed that TF was administered orally once per day for two consecutive weeks. IRs were 53.26%, 35.94%, and 26.74%, respectively. T/Cs were 59.74%, 69.66%, and 84.82%, respectively. RT-PCR experiments showed that compared with model group, when TF concentration was 30 g ·L-1, mRNA expressions of PI3K, Akt1, and Bcl-2 were significantly down-regulated, and mRNA expressions of tumor suppressor genes p53, Capsase-3, and Bax were significantly up-regulated. Immunohistochemical method results showed that compared with model group, at TF concentrations of 30, 15 g·L-1, all PI3K, Akt1, Bcl-2 protein expressions were significantly down-regulated, while p53, Capsase-3, Bax protein expressions were significantly increased. Conclusion: TF has an obvious anti-liver cancer activity in vivo. Its mechanism may be correlated with up-regulation of expressions of p53, Caspase-3, and activation of apoptosis PI3K/Akt/p53 pathway, thereby inhibiting Bcl-2, increasing expression of Bax, and promoting hepatocellular apoptosis.

Efficacy and safety of aspirin for venous thromboembolism after total knee arthroplasty / 中国组织工程研究

BACKGROUND: The best prevention strategy for venous thrombosis (VTE) is currently controversial, especially for patients with high risk of total knee arthroplasty. There are no fully safe, effective and inexpensive thrombus prevention drugs. OBJECTIVE: To study the efficacy and safety of aspirin in preventing venous thrombosis after total knee arthroplasty. METHODS: 300 patients undergoing primary unilateral total knee arthroplasty from September 2014 to December 2016 were randomly divided into two groups: conventional anticoagulation group and risk stratification group (n=150 per group), including 88 males and 212 females at the age of 49-85 years old. The conventional anticoagulation group received low molecular weight heparin for prevention and treatment. Risk stratification group was stratified according to the risk of venous thrombosis. 64 patients with low risk were treated with aspirin and 86 patients with high risk were treated with low molecular weight heparin. Complications were analyzed within 90 days after surgery, including deep venous thrombosis, pulmonary embolism, wound infection, bleeding and death. RESULTS AND CONCLUSION: (1) Complications occurred in 39 cases (13%) within 90 days after follow-up. The total incidence of symptomatic deep vein thrombosis complications was 2% in 6 cases, and 19 cases (6.33%) had wound complications. There were 3 cases (2%) of symptomatic deep vein thrombosis in conventional anticoagulation group and 3 cases (2%) in risk stratification group. (2) The incidence of symptomatic deep vein thrombosis, proximal deep vein thrombosis and distal deep vein thrombosis and pulmonary embolism were 1.56% (1 case), 1.56% (1 case), 4.68% (3 cases), and 0% respectively in patients treated with aspirin. The incidence of symptomatic deep vein thrombosis, proximal deep vein thrombosis and distal deep vein thrombosis and pulmonary embolism in patients receiving low molecular weight heparin were 2.12% (5 cases), 0.85% (2 cases), 5.08% (12 cases) and 0.42% (1 case), respectively. There was no significant difference between the two groups (P > 0.05). (3) There were 11 cases of wound complications in the conventional anticoagulation group and 8 cases in the risk stratification group (χ2 = 506, P = 0.318). (4) The incidences of wound-related complications (wound delayed healing, superficial wound infection and deep wound infection) were 1.56% (1 case), 0% and 1.56% (1 case) respectively in patients receiving aspirin, and 5.51% (13 cases), 1.27% (3 cases) and 0.42% (1 case) in patients receiving low molecular weight heparin. (5) Results suggested that aspirin and low molecular weight heparin can effectively prevent the occurrence of deep vein thrombosis. For low-risk patients, aspirin multi-mode thrombosis prevention is safe and effective.

The Effect of PCSA with Parecoxib Sodium and Sufentanil on the Postoperative Delirium in Patients after the Spinal Surgery / 昆明医科大学学报

Objective To investigate the effect of patient controlled subcutaneous analgesia (PCSA) of Sufentamil and Parecoxib sodium on the postoperative delirium in patients after the spinal surgery. Methods 240 patients with ASA Ⅱ- Ⅲ age 18-64 yrs after the spinal surgery were divided into two groups: group NO-PCSA (analgesic management: patients were accepted pethidine 25-50 mg intramuscular injection n = 120 );group PCSA (analgesic management: patient controlled subcutaneous analgesia was started since skin suture with the following composition:Sufentanil 0.9 ug/(kg.d)+Parecoxib sodium 120 mg+Tropisetron 10 mg+normal saline 150 mL. The PCSA setting was as follows:background infusion at 2 mL/h, a bolus dose of 0.5 mL, lockout interval 15 min. If the VAS was greater than 5, patient was accepted pethidine 25-50 mg intramuscular injection n=120) . The effect of analgesia was assessed by visual analogue scale (VAS) . The delirium was assessed by the confusion assessment, VAS and delirium were recorded with in 2, 24, 48, 72 hours postoperatively. Results During the analgesia period, the VAS and the incidence of postoperative delirium were significantly lower in group PCSA than those in group NO-PCSA ( <0.05) . Conclusion PCSA of Sufentamil and Parecoxib sodium have a good postoperative analgesic effect in patients after the spinal surgery. It is an effective measure and the incidence of postoperative delirium can be decreased by reliefing postoperative pain.

Contrast Researches of Liver Biopsy and Ultrasound in the Diagnosis of Fatty Liver / 昆明医科大学学报

Objective To evaluate the significance of liver biopsy and B ultrasonograpgy in the diagnosis of fatty liver. Methods The results of 62 patients with liver steatosis diagnosed by liver puncture biopsy but not by B-ultrasonograpgy were contrastively analyzed and combined with liver function, blood lipids, blood glucose, and body mass index. Results The 62 cases which were not diagnosed as fatty liver by B-ultrasonograpgy were proved to be 5％-33％liver steatosis after liver puncture biopsy. Among the 62 cases, 23 cases were indicated by the B-ultrasonograpgy that the liver parenchyma echo did not see abnormalities, 18 cases showed the liver parenchyma echo slightly was enlarged, 17 cases showed the liver parenchyma echo density was a bit enhanced and 4 cases were diffuse liver damage,which respectively were 37.01％、29.03％、27.42％and 6.45％. Pathologically it indicated that 45 cases were 5％≤liver steatosis≤19％. Among the 45 cases, 18 cases were indicated by the B-ultrasonograpgy that the liver parenchyma echo was not seen abnormalities, 8 cases showed the liver parenchyma echo slightly was enlarged, 17 cases showed the liver parenchyma echo density was a bit enhanced, and 2 cases were diffuse liver damage, and the change of ultrasound was mainly showed by the liver parenchyma echo not seen abnormalities and the enhanced liver parenchyma echo density. Pathologically it indicated that 17 cases were 20％≤liver steatosis≤33％, 6 cases were indicated by the B-ultrasonograpgy that the liver parenchyma echo did not see abnormalities, 5 cases showed the liver parenchyma echo slightly was enlarged, 5 cases showed the liver parenchyma echo density was a bit enhanced, and 1 case was diffuse liver damage, and the change of ultrasound was mainly showed by the liver parenchyma echo not seen abnormalities, the slightly enlarged liver parenchyma echo and the enhanced liver parenchyma echo density. By analyzing the influence to the ultrasound changes by patients' liver function, body mass index, blood fat and blood sugar, and with logistic regression analysis through a disorderly classification, it was found that the larger value of the glutamine transferase, alkaline phosphatase, body mass index, triglyceride and low density lipoprotein cholesterol, the higher possibility of diffuse liver damage, and the higher level of fatty degeneration, the higher possibility of diffuse liver damage. Conclusion In the diagnosis of fatty liver, when the fatty degeneration is below 1/3, B-ultrasonic examination can't show characteristic changes of fatty liver. It should be closely observed or take liver puncture biopsy to make a definite diagnosis of fatty liver.
