OBJECTIVETo investigate the clinical efficacy of Shexiang Injection (SI) on inflammatory reaction in patients with acute cerebral infarction (ACI).

METHODSForty-two patients with ACI were randomly divided into two groups, 21 in each group. The control group treated with conventional therapy and the SI group treated with conventional therapy plus SI. Besides, 21 healthy people were arranged in the normal group for control. Expression of CD54 of mononuclear cell (MC-CD54) and serum level of soluble vascular cell adhesion molecule-1 (sVCAM-1) were determined and the clinical efficacy was observed dynamically before treatment and on the 7th, 14th day of the course.

RESULTSLevels of MC-CD54 expression and sVCAM-1 in the ACI patients increased obviously (P < 0.01), reached the peak on the 7th day, and declined obviously on the 14th day in both groups, however, the lowering in the SI group was more significant than that in the control group (P < 0.01); and positive correlation was shown between these two indexes (P < 0.01). After treatment, score of neural defect was improved more significantly (P < 0.01), and the markedly effective and curative rate was higher in the SI group than those in the control group (P < 0.05), respectively.

CONCLUSIONSI could inhibit the subsequent inflammatory reaction, and thus improve the clinical efficacy of conventional therapy in treating patients with ACI.

Methods Nasopharyngeal secretions were collected from 4389 children with acute respiratory tract infection in outpatient department from January 2007 to September 2013, 9 common respiratory viruses were analyzed by Multiplex RT-PCR, including inlfuenza virus (FLU), parainlfuenza virus (PIV), respiratory syncytical virus (RSV) , adenovirus (ADV), human bocavirus(HBOV), human coronavirus(Cov), enterovirus(EV), human metapneumovirus(HMPV), and rhinovirus(HRV). The same analysis was done in 123 asymptomatic children during the same period. Results The positive rate of detected respiratory viruses in children with respiratory tract infections in nasopharyngeal secretions were 34.8% (1526/4389), including FLU 10.3% (453/4389), RSV 7.3% (320/4389), PIV 6.2%(274/4389), ADV 3.3%(146/4389), HBOV 2.7%(118/4389), EV 2.5%(110/4389), Cov 2.4%(105/4389), HRV 1.6%(72/4389), HMPV 1.5%(67/4389);two and more combined respiratory viral infection were found in 273 cases (6.2%). The virus detection
rate between age groups was signiifcantly different (χ2=41.91, P<0.001). The school-age group had the lowest positive rate of 23.4%and the positive rates in other three groups were all higher than 35.0%. The infant group had the higher positive rate of RSV and HRV. FLU detection rate in school-age group was 13.6%. Respiratory viruses in children with asthmatic disease has high detection rate. RSV infection rate was the highest 14.8%(30/204) in the asthmatic disease group, followed by HBOV 13.8% (28/204). In nasopharyngeal secretions of 123 asymptomatic children, virus-positive detection rate of 6.5% (8/123), which showed signiifcant difference from that in respiratory virus infection group (χ2=42.60, P<0.001). Conclusions In seven consecutive years of testing, the inlfuenza virus and respiratory syncytial virus play an important role in children with respiratory tract infections in this region. The detection rate of virus showed difference between different age groups and a higher detection rate of RSV in infants with respiratory tract infections was observed. The overall detection rate of virus was decreased with the increase of age excluding the inlfuenza virus.

Objective To observe the clinical efficacy of Bai Xiao moxibustion plus electroacupuncture in treating lumbar intervertebral disc herniation (LIDH). Method Ninety-six LIDH patients were randomized into a treatment group and a control group, 48 cases each. The treatment group was intervened by Bai Xiao moxibustion plus electroacupuncture, while the control group was intervened by electroacupuncture alone. Before and after the treatment, the lower back pain scores of Japanese Orthopedic Association (JOA) and Visual Analogue Scale (VAS) were evaluated, and the clinical efficacies of the two groups were compared. Result The JOA and VAS lower back pain scores were changed significantly after the treatment in both groups (P<0.05). After the treatment, the JOA and VAS lower back pain scores of the treatment group were significantly different from those of the control group (P<0.05). The pain release time was (2.95±0.59)d after the intervention in the treatment group versus (4.26±0.68)d in the control group, and the between-group difference was statistically significant (P<0.05). The total effective rate was 95.7％ in the treatment group versus 91.7％ in the control group, and the between-group difference was statistically significant (P<0.05). Conclusion Bai Xiao moxibustion plus electroacupuncture is an effective method in treating LIDH and it can reduce the lower back pain.

Objective To explore the application of endometriosis fertility index (EFI) in guidance after laparoscopic surgery of endometriosis patients combined with infertility and to explore methods to improve pregnancy rate in different EFI groups. Methods A prospective research was done in endometriosis patients combined with infertility in Beijing Obstetrics and Gynecology Hospital from January 2010 to June 2011, after laparoscopic surgery, these 146 patients were divided into 3 groups by EFI score. Using different pregnancy guidance, these patients had 5 years follow-up. Results (1) The 5 years overall pregnancy rate was 89.0%(130/146). The pregnancy rate was 95.7%(45/47) in EFI≥9 group, 92.8%(77/83) in EFI 5-8 group and 8/16 in EFI≤4 group, three groups were all reach satisfactory pregnancy rate;the rate of the first two groups had no statistically significance (P=0.498), but had significant difference with the last group (P<0.01). (2) In EFI≥5 patients, pregnancy rate was the highest in 6 months after operation;in EFI≥9 group, the pregnancy rate was 66.7%(30/45), and EFI 5-8 group was 50.6%(39/77). (3) EFI≥9 group had the highest natural pregnancy rate [83.6% (46/55)], natural pregnancy rate was significant statistical different in different EFI groups (P=0.001). Conclusions EFI score is a useful evaluation in predicting and guiding pregnancy in endometriosis patients combined with infertility after laparoscopic surgery. EFI score guidance, strict post-operation management and positive pregnancy scheme could significantly improve the pregnancy rate of endometriosis patients with infertility.

Objective To explore the expression of HCK gene during the cardiomyocyte differentiation of mouse embryonic stem cells and analyze the role of HCK gene in maintenance of pluripotency of embryonic stem cells.Methods Mouse embryonic stem cells were cultured,then induced to differentiate into cardiomyocytes.Total RNAs were isolated from mouse embryonic stem cells in the differentiation days:0 day(D0),the second day(D2),the fourth day(D4),the sixth day(D6),the eighth day(D8),respectively.The levels of HCK mRNAs were assessed by the method of semi-quantitive reverse transcriptase-polymerase chain reaction(RT-PCR).In the meanwhile,Total proteins were also isolated from mouse embryonic stem cells in the differentiation D0,D2,D4,D6,D8,and the levels of HCK proteins were evaluated by Western-blot.Results HCK mRNAs could be detected in the mouse embryonic stem cells in D0 and D2,however,they were undetectable from D4 to D8.The expression of HCK mRNAs was rapidly down-regulated during cardiomyocyte differentiation of mouse embryonic stem cells.Expression of HCK proteins,which coincided with HCK mRNAs,down-regulated during differentiation and couldn't be detected in D4.Conclusions With the cardiomyocyte differentiation of mouse embryonic stem cells,the expression of HCK in the levels of mRNA and proteins are sharply down-regulated;HCK may play an important role in maintaining the pluripotency of embryonic stem cell.

Objective To explore the approach and early effects of endovascular stent-graft deployment in the treatment of portal stenosis of cancerous thrombus.Methods Six cases with portal vein stenosis of cancerous thrombus,which caused by primary hepatic carcinoma(5 cases)and eholangiocarcinoma(1 case)and the severity of stenosis showed on contrast enhanced CT were more than 75% or occluded,were performed percutaneous transhepatie or transsplenic portography.FLUENCY~(TM) endovascular stent-graft(10 mm diameter)was placed at the position of stenosis after gastroesophageal varices embolization.Portal pressure was measured pre-and post-deployment.Results Stents were successfully placed in all patients.The average portal pressure decreased from 50.7 cm H_2O(1 cm H_2O = 0.098 kPa)to 41.3 cm H_2O after endovascular stent-graft deployment.The restenosis were found in 2 cases after one month.Haematemesis and refractory aseites appeared in one case respectively,the other 4 cases showed no significant symptoms above caused by portal hypertension.Conclusion It is safe and feasible for endovaseular stent-graft deployment in the treatment of portal stenosis of cancerous thrombus.Selecting the suitable indications,the symptoms of portal hypertension can be controlled effectively.

Aim To identify the potential biomarkers associated with carbon tetrachloride(CCl 4 )-induced a-cute hepatic injury in rats and explore the therapeutic effect of Hugan Tablets(HGT). Methods The model was established by intraperitoneal injection of CCl4 in oil(1 : 1,V/ V)with a dosage of 1 mL·kg - 1 body weight to rats once. The levels of aspartate aminotrans-ferase(AST),alanine aminotransferase(ALT),alka-line phosphatase (ALP ) and lactate dehydrogenase (LDH)in serum of rats were determined. Moreover,a proton nuclear magnetic resonance (1 H-NMR)based metabonomic approach in combination with multivariate data analysis was applied to demonstrate CCl4-induced acute hepatic injury metabolic perturbations in rat urine and feces and identify the corresponding metabolic bio-markers. The intervention effect of HGT was evaluated based on the changes of metabolic phenotype and po-tential biomarkers related to acute hepatic injury. Re-sults The levels of AST,ALT,ALP and LDH in ser-um of rats with acute hepatic injury were significantly reduced by administration of HGT,respectively. The disturbed metabolic state associated with CCl4-induced acute hepatic injury in rat urine and feces could be re-stored by HGT. Meanwhile,five potential biomarkers (2-oxoglutarate,citrate,creatinine,trimethylamine N-oxide,hippurate)in rat urine and three potential bio-markers(butyrate,glucose,uracil)in rat feces related to acute hepatic injury were reversed by administration of HGT,respectively. Conclusion HGT exerts pro-tective effects against CCl4-induced acute hepatic inju-ry in rats,which is probably mediated by regulation of tricarboxylic acid cycle and gut microbiota metabolism.

Objective To stimulate the expansion of natural killer cells (NK) in vivo, to achieve high expression of Flt-3 ligand ( FL) in the mouse liver by hydrodynamic injection technology , to obtain high purity of NK for cell therapy and then to purify the spleen lymphocytes by MicroBeads sorting ( MACS ) technique.Methods C57BL/6 mice were repeatedly treated with hydrodynamic injection of FL expression plasmid .Then, surface markers of splenic NK were analyzed by flow cytometry and purified by MACS technique .Results Compared with mice treated with one hydrodynamic injection, the spleen of mice treated with two hydrodynamic injections showed significant variation, with the absolute num-ber of lymphocytes increased (6.02 ±1.15) times, the proportion of NK subsets increased (2.07 ±0.39) times, and the absolute number of NK subsets increased (12.49 ±2.39) times.Cell surface marker detection confirmed that NK activity and surface markers did not change significantly .NK with a purity of about (83.81 ±0.92)％ was obtained by the combination of two magnetic beads sorted with CD 5 ( Ly-1) MicroBeads Positive selection and EasySep TM Mouse NK Cell Isolation Kit negative selection .Conclusion NK can be expanded in the spleen of mice by hydrodynamic injection of FL plasmid without influence on the NK activity and surface markers.The combined use of CD5 (Ly-1) MicroBeads positive selection with EasySep TM Mouse NK Cell Isolation Kit negative selection can effectively remove T , B and other miscellaneous cells, thereby contributing to obtaining high-purity NK. This study provides good reference for the immunotherapy of tumor cells.
