Objective:To evaluate the clinical effect of Limb dysfunction after the comprehensive treatment of ischemic stroke by Traditional Chinese Medicine (TCM).Methods:A total of 160 patients with limb dysfunction after ischemic stroke. Who in line with the inclusion criteria, were randomly divided into 2 groups by random number table, 80 cases each. These patients were treated in Multicenter Union Hospital from June 2017 to Janunry 2019. The patients in the control group were given basic Western medicine treatment and rehabilitation training, while the patients in the observation group were given a comprehensive treatment combined with traditional Chinese medicine based on the control group (Chinese herbs, herbal fumigation and ear point press). Both groups were treated for 4 weeks and follow-up for 2 months. The Fugl-Meyerscale were used to evaluate the degree of limb dysfunction and balance dysfunction, the National Institutes of Health Stroke Scale were used for assessing the damage extent of nerve function, the Barthel index for evaluating the mobility of daily life. The clinical efficacy was evaluated according to the method of Brunnstrom assessment.Results:After treatment, the Limb strong spasm (1.57 ± 0.36 vs. 1.98 ± 0.53, t=5.724), Hemianesthesia (1.37 ± 0.31 vs. 1.80 ± 0.36, t=8.096), Inhibited bending and stretching (1.31 ± 0.25 vs. 1.84 ± 0.46, t=9.055) in the observation group were significantly lower than those in the control group ( P<0.01). The Fugl-Meyer activity and balance rating in the observation group were significantly higher than those in the control group ( t values were 2.739, 4.705, respectively, P<0.05 or P<0.01). The total effective rate of observation group was 93.3% (78/80), the control group was 73.3% (71/80), and there exist statistical significance ( χ2=4.783, P=0.028) in the two group’s comparative difference. Conclusion:The comprehensive TCM treatment can improve the hemiplegia syndrome of ischemic stroke patients and their limb activity and balance function, promote their neural functional recovery, enhance the activity of their daily life and clinical efficacy.

Objective To explore the status of histone acetylation modification and their regulatory effect to hMSH2 gene and hMLH1 gene expression in acute leukemia. Methods Reverse transcription-polymerase chain reaction (RT-PCR) was used to measure the expression of hMSH2 and hMLH1 mRNA, and Western blot was used to measure the expression of histone H3, H4, HDACi, hMSH2 and hMLH1 protein in mononuclear cells of 56 acute leukemia patients and 30 healthy volunteers. The mononuclear cells of 30 acute leukemia patients were treated with histone deacetylase inhibitors trichostatin A (TSA), and measured the expression difference of histone H3, H4, HDAC1, hMSH2 and hMLH1 in the mononuclear cells treated with TSA. Results The protein expression levels of hMSH2, hMLH1, histone H3 and histone H4 in those mononuclear cells of acute leukemia patients were 0.4610±0.1211, 0.4013±0.1143, 0.4103±0.1241 and 0.4251±0.1081, respectively, which were significantly decreased comparing with those of healthy volunteers (0.9461±0. 1841, 0.996±0.2021, 0.8971±0. 1194 and 0.9513±0.1953) (t = 3.341, 3.935, 2.843 and 3.575,respectinely, P ＜0.05). The protein expression levels of HDAC1 (0.8841±0.2018) of acute leukemia patients was significantly increased comparing with those of healthy volunteers (0.5142±0.1340) (t= 2.634, P ＜0.05).After treatment with TSA for 48 hours, the protein expression of hMSH2 was increased nearly 1.5-fold, hMLH1 about 1.6-fold, H3 about 2.9-fold and H4 about 3.4-fold comparing with the negative control groups (P ＜0.05),while the protein expression of HDAC1 were decreased comparing with the negative control groups by 40 %.Conclusion There was an low expression phenomenon of histone acetylation in acute leukemia, and histone acetylation played an important role in regulation of the mismatch repair gene expression in acute leukemia.

Objective To investigate the expression of DRAM in breast cancer cell line MCF-7 in radiation-induced autophagy. Methods GFP-LC3 transfection method was used to observe autophagy bubble.Real time-PCR was used to detect DRAM and MAPLC3 from transcriptional and translational level,respectively. The silencing vector from gene engineering was introduced by calcium phosphate transfection.Results Compared with the control group,GFP-LC3 increased significantly after 8 Gy irradiation by immunofluorescent assay,and the level of MAP-LC3 expression was higher than control group after 8 Gy irradiation by Western blot ( F =5.38,8.72,10.63,15.23,20.78 and 55.23,P ＜ 0.05 ).DRAM protein expression increased significantly at 2 h in the 8 Gy time-dose study,up to maximum at the 32 h( F =116.34,P ＜ 0.05 ).In DRAM model,the expression of LC3 and DRAM decreased significantly (F =20.36 and 40.35,P ＜ 0.05 ) and DRAM expression increased 8 Gy post-irradiation,but still lower than that in 8 Gy irradiation wild-type group.The LC3 expression also decreasaed 8 Gy post-irradiation(F =50.34,P ＜ 0.05 ).Conclusions DRAM plays an important role in irradiation-induced autophagy in breast cancer cell.DRAM might participate in the process and serve as a theoretical target for clinical treatment of breast cancer.

Objective: To analyze the related factors of postoperative complications after laparoscopic assisted D2 radical resection for advanced gastric cancer. Methods: From August 2015 to July 2017, 80 patients with advanced gastric cancer admitted to the First Hospital of Jiaxing were selected.All the patients were treated with laparoscopic-assisted D2 radical resection, and the risk factors related to postoperative complications were analyzed by logistic regression analysis model. Results: There were 33 cases (41.25%) with postoperative system complications, 19 cases (23.75%) with complications of level Ⅱ and above; 15 cases (18.75%) with postoperative local complications, among them 12 cases (15.00%) appeared level Ⅱ and above local complications.The number of concomitant diseases and age were related risk factors for systemic complications in patients with advanced gastric cancer after laparoscopic D2 radical resection (OR=1.982, 95%CI: 2.183-34.405, OR=6.587, 95%CI: 1.738-23.495, all P<0.05).

Objective To evaluate the value of shear wave elastography(SWE) in the diagnosis of gastroesophageal varices in patients with hepatitis B-related hepatocellular carcinoma(HCC). Methods From October 2016 to May 2017,a total of 325 patients with hepatitis B-related HCC received conventional ultrasonography and SWE examinations in Shanghai Eastern Hepatobiliary Surgery Hospital were selected. The basic clinical data,conventional ultrasonography,SWE examination parameters and gastroscopy results of 192 patients were successfully collected. The training group ( 120 cases) and the validation group (72 cases) were divided from these patients according to the time order of entering the study.The gastroscopy results were used as the gold standard and the training group were analyzed using univariate and multivariate analysis.A new GOV diagnostic model was established and the diagnosis value of which were validated and evaluated in the validation group. Results Among 9 parameters studied,the maximum flow velocity of the portal vein,the thickness of the spleen and the stiffness of the spleen were independent factors affecting GOV in patients with hepatitis B-related HCC with odds ratio of 0.755(95% CI 0.617-0.924),1.375(95%CI 1.171-1.614) and 1.093(95% CI 1.043 -1.145),respectively(all P < 0.01).T he area under ROC curve of GOV diagnostic model that containd these 3 parameters diagnosing GOV in validation group was 0.914 (95% CI,0.832~0.995).The -1.49 was the best cut-off value with sensitivity,specificity,positive predictive value,negative predivtive value and coincidence rate of 79.0%,92.5%,91.3%,81.5% and 85.8%,respectively. Conclusions The GOV diagnostic model established by combining SWE and conventional ultrasonography is of certain value in diagnosis of GOV in patients with hepatitis B-related HCC yet needs further validation.

Objective:To explore the effect of distal veins on the survival of a dorsal four-territory perforator flap in rats.Methods:A total of 32 SD rats were randomly divided into the control group and the experimental group, with 16 rats in each group. The multi-territory perforator flap including the bilateral iliolumbar and bilateral posterior intercostal angiosomes was cut from the back of each rat, with the size of 6 cm×7 cm. The right iliolumbar artery and vein were preserved in the control group, while the right iliolumbar artery and the right posterior intercostal vein were preserved in the experimental group. In both groups, incisions were made between the right iliolumbar angiosome and the right posterior intercostal angiosome. Finally, the flap was sutured back to their orthotopic site. At 6 hours and 1, 3, 5, 7 days after surgery, the blood perfusion at the bilateral iliolumbar and the left posterior intercostal vascular territories were measured. On the seventh day after surgery, the percentage of the survived area of the flaps were evaluated, arteriography was performed to observe the dilation of arteries within the flap, the intraluminal diameter of the choke artery in the choke 2 area was measured using hematoxylin and eosin staining, and the relative expression of endothelial nitric oxide synthase (eNOS) was detected by Western blotting. SPSS 28.0 was used for statistical analysis, and measurement data were presented as Mean±SD. Independent sample t-test was used to compare data across two groups. P<0.05 was considered statistically significant. Results:(1) At 6 hours and 1, 3, 5, 7 days after surgery, the experimental group displayed higher blood perfusion than the control group at the bilateral iliolumbar and the left posterior intercostal vascular territories (all P<0.01). (2) On the 7th day after surgery, the artery dilation of the experimental group was more obvious than that of the control group; the percentage of the survived flap area in the experimental group was higher than that in the control group [(87.6±3.2)% vs. (65.3±3.0)%, P<0.01]; the intraluminal diameter of the choke artery was greater in the experimental group than that in the control group[(49.3±3.1) μm vs. (35.1±2.3) μm, P<0.01]; and the relative expression of eNOS in the experimental group was higher than that in the control group (0.87±0.07 vs. 0.50±0.05, P<0.01). Conclusion:The distal vein (right posterior intercostal vein) of dorsal four-territory perforator flap of SD rats directly guided the pedicle artery blood supply to promote the expression of eNOS, dilated the arteries in each zone of the flap, increased the blood supply to the distal artery of the flap, and ultimately enhanced the flap survival area.

Objective The aim of this study was to explore the role and mechanism of ferroptosis in SiO2-induced cardiac injury using a mouse model. Methods Male C57BL/6 mice were intratracheally instilled with SiO2 to create a silicosis model.Ferrostatin-1(Fer-1)and deferoxamine(DFO)were used to suppress ferroptosis.Serum biomarkers,oxidative stress markers,histopathology,iron content,and the expression of ferroptosis-related proteins were assessed. Results SiO2 altered serum cardiac injury biomarkers,oxidative stress,iron accumulation,and ferroptosis markers in myocardial tissue.Fer-1 and DFO reduced lipid peroxidation and iron overload,and alleviated SiO2-induced mitochondrial damage and myocardial injury.SiO2 inhibited Nuclear factor erythroid 2-related factor 2(Nrf2)and its downstream antioxidant genes,while Fer-1 more potently reactivated Nrf2 compared to DFO. Conclusion Iron overload-induced ferroptosis contributes to SiO2-induced cardiac injury.Targeting ferroptosis by reducing iron accumulation or inhibiting lipid peroxidation protects against SiO2 cardiotoxicity,potentially via modulation of the Nrf2 pathway.

AIM: To study the bioequivalence of two tadalafil tablets in Chinese healthy male subjects. METHODS: A randomized, open-label, two-period, two-sequence, crossover study designing was adopted in the study. Thirty-six healthy male subjects were enrolled under fasting condition and fed condition, respectively. Each subject was given a single oral dose of tadalafil tablet (20 mg). The concentration of tadalafil in plasma was determined by LC-MS/MS. The pharmacokinetic parameters were calculated by WinNonlin 8.0 program, and statistical analysis was performed by using SAS 9.4 statistics software. RESULTS: Under fasting condition, the pharmacokinetic parameters of tadalafil of the test (T) and reference (R) preparation were as follows: C

OBJECTIVE: To investigate the associations between chronic kidney disease (CKD) and body mass index (BMI), waist circumference(WC), waist-to-height ratio (WheiR) in Chinese adults.
 METHODS: A total of 26 655 participants, who voluntarily attended annual health examination at the Health Management Center in the Third Xiangya Hospital of Central South University from June 2013 to February 2014, were enrolled for this study. Logistic regression and receiver operating characteristic (ROC) curve analysis were performed.
 RESULTS: The prevalence rate of CKD was 9.6% and 3.1% in male and female subjects, respectively. Multivariate logistic regression analysis showed that BMI, WC and WheiR were independent risk factors for CKD in diabetic male and hypertensive male subjects (P<0.01). However, no association between these obesity indices and CKD was found in women after multivariate adjustment. In diabetic male subjects, when BMI≥28.7 kg/m(2), WC=90.7 cm and WheiR=0.56, the sensitivity and specificity prediction for CKD was 24.8%, 58.5%, 45.5% and 83.3%, 54.4%, 69.6%, respectively. In hypertensive male subjects, when the optimum cut-off points for BMI, WC and WheiR were ≥
27.0 kg/m(2), 91.2 cm and 0.54, the sensibility prediction for CKD were 41.0%, 47.0% and 50.1%, respectively, while the specificity prediction were 68.0%, 63.0% and 61.4%, respectively. The area under the ROC curve of BMI, WC, WheiR for CKD prediction were 0.56, 0.57, 0.59 in diabetic male subjects and 0.54, 0.56, 0.57 in hypertensive male subjects, respectively.
 CONCLUSION BMI, WC and WheiR are associated with the increased risk for CKD in diabetic or hypertensive male subjects. However, the value for these obesity indices is limited in screening CKD.
