OBJECTIVETo investigate whether intracytoplasmic sperm injection (ICSI) can improve the clinical outcomes of the male patients with 100% teratozoospermia.

METHODSWe retrospectively analyzed the clinical data of 152 couples undergoing in vitro fertilization-embryo transfer (IVF-ET), including 75 cycles of IVF and 77 cycles of ICSI. We compared the rates of normal fertilization, high-quality embryos, transferrable embryos, implantation, clinical pregnancy, and abortion between the two groups.

RESULTSIn the 100% teratozoospermia patients the number of transferrable embryos was significantly lower in the IVF than in the ICSI group (78.91% vs 84.92%, P < 0.05), while the rates of normal fertilization and implantation were higher in the former than in the latter (60.26% vs 57.87% and 48.00% vs 39.55%, both P > 0.05). There were no statistically significant differences between the two groups in the female age, Gn days, Gn dose, BMI, infertility duration, endometrial thickness, and basal serum FSH and E2.

CONCLUSIONICSI cannot improve the clinical outcomes of the male patients with 100% teratozoospermia.

AIM To investigate the ameliorative effects of Schisandrol A(Sol A)in Suhuang antitussive capsule on post-infectious cough(PIC).METHODS The in vivo mouse PIC model was established by intratracheal instillation of lipopolysaccharide(LPS)combined with cigarette smoke exposure.The mice were randomly divided into the control group,the model group,the Suhuang antitussive capsule group(14 g/kg),the montelukast sodium positive control group(3 mg/kg),and low and high dose Sol A groups(10,30 mg/kg).The in vitro PIC model was established by stimulating human bronchial epithelial cells(BEAS-2B)with LPS.The cells were divided into the control group,the model group,the Suhuang antitussive capsule group(10 μg/mL)and low and high dose Sol A groups(3,10 μmol/L).HE and Masson staining were used to detect the pathological changes of the lung and bronchial tissues.ELISA was used to detect the levels of IL-1β,IL-6,TNF-α,ROS,MDA,SOD and GSH in the lung tissues.RT-qPCR was used to detect the IL-1β,IL-6 and TNF-α mRNA expressions in BEAS-2B cells.And Western blot was applied to detect the protein expressions of p-PI3K,p-Akt,NOX4,SIRT1,p-ERK,Fibronectin,E-cadherin,Vimentin and α-SMA in mouse lung tissue and BEAS-2B cells.RESULTS Compared with the model group,the groups intervened with Sol A or Suhuang antitussive capsule displayed prolonged cough latency(P＜0.01);reduced cough frequency(P＜0.01);relieved pulmonary inflammatory cell infiltration and collagen deposition in PIC mice;decreased pulmonary levels of IL-1β,IL-6,TNF-α,ROS,MDA and protein expressions of Fibronectin,Vimentin,α-SMA,p-ERK,p-PI3K,p-Akt,and NOX4(P＜0.05,P＜0.01);increased pulmonary levels of SOD and GSH and protein expressions of E-cadherin and SIRT1(P＜0.05,P＜0.01);decreased ROS level,IL-1β,IL-6,TNF-α mRNA expressions and p-ERK,p-PI3K,p-Akt,NOX4 protein expressions in vitro(P＜0.05,P＜0.01);and increased SIRT1 protein expression in vitro as well(P＜0.01).CONCLUSION Being the main antitussive component of Suhuang antitussive capsule upon the PIC model,Sol A inhibits the inflammation via SIRT1/ERK signaling pathway and relieve the oxidative stress via PI3K/Akt/NOX4 signaling pathway.

AIM To explore the effects of praeruptorin A from Suhuang antitussive capsules on cough variant asthma(CVA).METHODS The rats were randomly divided into the normal group,the model group,the dexamethasone group(0.5 mg/kg),the Suhuang antitussive capsules group(7 g/kg)and the low,medium and high dose praeruptorin A groups(15,30 and 60 mg/kg).The rat model of CVA was established by intraperitoneal injection of sensitizer(1 mg/mL ovalbumin and 10 mg/mL aluminum hydroxide)and aerosol inhalation of 1%ovalbumin followed by the corresponding dosing of drugs by gavage initiated on the 14th day.Another 14 days later,the rats had their pathological pulmonary changes observed by HE,Masson and PAS stainings;their number of inflammatory cells in bronchoalveolar lavage fluid(BALF)detected by hematology analyzer;and their levels of IL-4,IL-5,IL-13 and MUC5AC in BALF detected by ELISA.The RAW264.7 cell inflammatory model induced by lipopolysaccharide(LPS)was treated with 4,8,16 μmol/L praeruptorin A or 0.25 mg/mL Suhuang antitussive capsules,respectively.And the cells had their NO level detected by Griess method,and their ROS expression observed using fluorescence microscopy.The detections of the pulmonary and cellular mRNA expressions of IL-6,IL-1β,COX-2,iNOS and PPAR-γ by RT-qPCR;and the protein expressions of p-P65,P65,p-IκBα,IκBα,NLRP3,caspase-1(p20)and IL-1β by Western blot were conducted in both the cells and the rats.RESULTS The in vivo result showed that praeruptorin A reduced the cough frequency(P＜0.01);prolonged the cough latency(P＜0.05,P＜0.01);reduced the number of eosinophils and neutrophils in BALF(P＜0.05,P＜0.01);decreased the levels of IL-4,IL-5,IL-13 and MUC5AC in BALF and the pulmonary mRNA expressions of IL-6,IL-1β,COX-2 and iNOS(P＜0.05,P＜0.01);and decreased the phosphorylation of P65 and IκBα protein and NLRP3,caspase-1(p20)and IL-1β protein expressions(P＜0.05,P＜0.01)as well.The in vitro result showed that praeruptorin A inhibited the release of LPS-induced NO and reduce the ROS level(P＜0.01);decreased the mRNA expressions of IL-1β,COX-2 and iNOS(P＜0.05,P＜0.01);increased PPAR-γ mRNA expression(P＜0.05),and decreased the phosphorylation of P65 and IκBα protein and the expression of NLRP3 protein(P＜0.05,P＜0.01).CONCLUSION Praeruptorin A,one of the main antitussive components of Suhuang antitussive capsules,may improve CVA because of its anti-inflammatory and antitussive role by inhibiting the activation of NF-κB signaling pathway and reducing the expression of NLRP3 inflammatory corpuscles.

OBJECTIVETo understand the pollution rates of vibrio cholera (V. cholera) in different seafood, aquatic products and their circulatory processes, so as to help making measures for cholera control and prevention.

METHODSDifferent seafood, aquatic products and breed water specimen collected from 12 provinces of China were tested from July to September in 2005.

RESULTA total of 12 104 samples of seafood and aquatic products were tested and the average pollution rate of vibrio cholera was 0.52%. The positive isolate rate of turtle sample (1.72%) was the highest among all samples. The second higher isolated rate was 1.14% in water specimen of turtle breed pool. The positive rate of bullfrog was 0.50%. The percentage of toxin strains was 47.54% and 79.31% of them were isolated from turtle and water samples of turtle breed pool. The important sector of the pollution of vibrio cholera was in turtle breed pool (2.38%).

CONCLUSIONThe average pollution rate of vibrio cholera in seafood and aquatic products in 12 provinces of China was low. It should be very necessary to supervise the sanitation in turtle breed for controlling and preventing the vibrio cholera.

OBJECTIVETo investigate the potentiality of herpes simplex virus thymidine kinase transduced endothelial progenitor cells (EPC-TK) as angiogenesis-targeting vector in the glioma treatment in vitro and in vivo.

METHODSEPC-TK were mixed with human umbilical vein endothelial cells (HUVECs), U87 or U251 cells at various ratios for ganciclovir (GCV) treatment. The bystander effect was observed by counting the survival cells using MTT assay, and the apoptotic cells were determined by annexin-V and propidium iodide (PI) staining. EPC-TK, EPCs, or phosphate buffered saline (PBS) were injected into the nude mice model of glioma xenograft by tail vein, for the EPC-TK group, EPC group, and PBS group, respectively. And then the changes of tumor volume and tumor vasculature were observed.

RESULTSGCV killed most EPC-TK and reduced the number of other viable cells in a cell:cell ratio-dependent and time-dependent manner. EPC-TK obviously inhibited tumor growth. The tumor volumes on day 21 were 1741.20+/- 576.10 mm(3), 3275.52 +/- 710.86 mm(3) and 3033.09+/-1134.86 mm(3) in the EPC-TK, EPC and PBS group, respectively. EPC-TK also displayed a significant effect on the inhibition of tumor angiogenesis.

CONCLUSIONEPC-TK can exert a potent antiglioma effect via inhibiting angiogenesis.

OBJECTIVETo investigate the correlation of pathology, bone morphogentic protein (BMP) expression, CT value with the ossification of thoracic ligamentum flavum (TOLF) to afford the evidence to choose appropriate treatment methods.

METHODSTwenty-three patients aged 35 - 65 years old had TOLF in my hospital as case. Their courses of disease were 2 months to 9 years. The values of blood calcium, blood phosphorus and AKP in them were normal. The 5 peoples aged 21 - 35 years old who presented fracture of thoracic but not the ligamentum flavum ossification were selected as control. We excluded those who have DISH, ankylosing spondylitis, fluorosis and other disease related with TOLF. The lesion locus were scanned and mensurated by CT. The pathology characteristics were classified into immature ossification and mature ossification by general observation, histology examination. BMP were measured by the immunohistochemical (IHC) staining techniques.

RESULTSThe CT value was significantly higher in the case group (547.2 +/- 131.4) than controlled group (137.7 +/- 10.6) (t = 6.922, P = 0.000). Further, the CT value in the mature ossification (702.9 +/- 17.7) was significantly higher than the immature (480.5 +/- 180.2) (t = 5.623, P = 0.000). In addition, BMP both expressed negative in the mature ossification and the controlled group, but positive in the immature ossification. BMP expression was significantly different between the immature ossification and the mature (chi2 = 70.000, P = 0.000).

CONCLUSIONSThe CT values, pathological types and BMP expression results are similar to evaluate the ossification degrees of ligamentum flavum, and then could be indirectly judged the maturation degrees of TOLF by CT to confirm the treatment methods before operation.

OBJECTIVETo assess the different causes of thoracic ossification of the ligamentum flavum (TOLF).

METHODSFrom July 1989 to November 2005, 142 cases were diagnosed the TOLF, in which 121 were operated. The lesions were classified into three types on the basis of the clinical result: (1) In such primary group (Group 1, 90 cases), without incorporation disease and Ca, P and AKP was all normal; (2) In systemic ossified TOLF group (Group 2, 30 cases), 6 cases ankylosing spondylitis, 3 cases DISH, 10 cases fluorosis, 11 cases OPLL; (3) In local spine disease group (Group 3, 22 cases), 5 cases fracture in spine, 4 cases spine TB, 13 cases posterior marginal intraosseous cartilaginous node. Such clinical feature was analysed, moreover surveyed the thoracic kyphosis angle, upper thoracic kyphosis angle, lower thoracic kyphosis angle and the vertebra body wedge change. The effect was assessed using Epstein Scale.

RESULTS(1) In Group 1, the mainly type was connected type (67/90, 74%). The ossified ligamentum flavum was mainly located at the lower thoracic and thoracic-lumber levels. The local type was less. In Group 2, the mainly type was connected type (21/30, 70%). The local type was none. The lesions figure was the most. In Group 3, the local type was the most (18/22, 82%). (2) In Group 1, the ossified ligamentum flavum was mainly located at the upper and lower thoracic levels (225/486, 47%). In Group 2, mainly located at the whole thoracic, some include cervix and lumber. In Group 3, mainly location was related with the location of primary disease. (3) In group 1, the curve was normal in 81% (73/90) of cases. In Group 2, the curve was abnormal in 87% (26/30) of cases. In Group 3, the curve was normal in the 82% (18/22) of cases.

CONCLUSIONSThe TOLF relates with systemic ossify disease, the change of load on the spine, aging and so on. It should be classified according to its causes.

OBJECTIVETo explore the distribution of deep inferior epigastric perforator vessel and application of the expanded perforator flap for large scar on hand and forearm.

METHODS20 healthy adults were selected to detect the distribution of deep inferior epigastric perforator vessel. 10 cases with cicatricial constriction on hand and forearm were treated with expanded perforator flap.

RESULTS425 perforator points were detected on the skin surface of abdomen in 20 adults. 80% of the points are located within the area which is 1.1 -5.8 cm far from the mid-line of abdomen. According to the Rand method, the percentage of the points in zone I , II , III were 26%, 43%, and 30%, respectively. There were few points in zone IV. The area around navel had a high density of points. The points were distributed asymmetrically at the two sides of abdomen. 10 cases were treated. Vascular deficiency happened at the distal end of one flap. All the other 9 flaps survived.

CONCLUSIONSThe expanded deep inferior epigastric perforator flap is thin and has a large size. It is very suitable for large scar on forearm or hand.
