Objective To systematically review the efficacy and safety of nicergoline on chronic cerebrovascular insufficiency (CCVI).Methods Databases including the Cochrane Library,PubMed,CNKI,VIP and WanFang Date were electronically searched for relevant randomized controlled trails (RCTs) which studied the effectiveness and safety of Nicergoline on chronic cerebrovascular insufficiency.Two reviewers independently screened literature according to the inclusion and exclusion criteria,extracted data,and assessed the methodological quality.Metaanalysis was performed by using RevMan 5.2 software.Results Totally 9 studies involving 1 030 patients were included.The meta-analysis results showed that,compared with conventional treatment alone,the Nicergoline group was superior in improving the velocity of middle cerebral artery(MCA) in both systolic(MD=16.43,95％CI:10.39-22.46) and the late diastolic (MD=11.48,95％CI:5.34-17.63).Besides,Nicergoline significantly improved the pulse index (PI) of MCA (MD=-0.37,95％CI:-0.48--0.26).Likewise,it obviously improved the velocity in both systolic (MD=11.23,95％CI:6.10-16.35),the late diastolic (MD=8.80,95％CI:5.20-12.40) and the PI of vertebral artery (VA) (MD=-0.38,95％CI:-0.47--0.28).The remission rate of the nicergolinegroup was higher than that of the control group (OR=3.93,95％ CI:2.66-5.81).Drug-related adverse reactions were not reported in included studies.Conclusions Nicergoline shows a certain efficacy on CCVI without obvious adverse reactions.

Objective To observe the lung inflammation and the expression of T - helper cell related cytokines in respiratory syncytial virus(RSV) infected Balb/c mice pre - sensitized with ovalbumin(OVA). Methods Mice were randomly divided into two series: nonsen-sitized and sensitized animal model with nebulized OVA once a day for 10 days. Each of the series was divided again into two groups: control group,RSV infected group with nasal draping plus nebulizing. All the mice were sacrificed 5 days later of infection. Viral isolation of lung organization was performed in each group. Pulmonary pathological detection and the levels of interleukin - 4(IL-4), interferon-? (IFN- ?) mRNA were evaluated by RT- PCR. Results The RSV were found only in RSV infected groups. The Balb/c mice developed typical interstitial pneumonia after RSV infection. When the mice pre- sensitized were infected with RSV, the pulmonary inflammation, lymphocyte and eosinophils infiltration and cell - collar peribronchiles were more severe in lung organization and bronchiole than those in the single RSV infection group. In the lung organization of control group, there were no mRNA expression of IL - 4 and IFN - ?. The mRNA of IFN -? was expressed in the lung organization of RSV infected groups while had not showed mRNA of IL- 4. In the OVA+ RSV group the mRNA expression of IL - 4 was obvious, while the expresses of IFN -? scarcely. Conclusions Pulmonary inflammation is more severe in the infection after OVA sensitization. RSV infection alone results in a Th1 - like cytokine response, while the infection after OVA sensitization results in Th2 - like response.

Objective To investigate the clinical result of reconstructed thumbs and fingers using frozen allogeneic composite tissues of fingers and autogenous toe Methods Fifty thumbs and fingers were reconstructed in 24 patients (25 hands) by allogeneic composite tissues of finger wrappoed by free neurovascular big toe nail skin flap and combined transplantation with autogenous second toe 15 patients were followed up for 4 years in average with examination in the ambulant clinic, communication and X ray photography to evaluate the clinical effect Results Recovered sensory function of the reconstructed fingers as well as good opposition function were seen There were Charcot's like arthrosis of allogeneic MP and arthroclisisof IP in 2 cases The postoperative gait of the doner's feet was normal The site of grafted skin on big toe was rubbed easily in 4 cases and the valgus hallexo of the doner's foot were seen in 3 cases, the plantaris callus in 2 cases Postoperative immunological rejection didn't elicit The junction between implanted allo phalangen tendon and autophalanges tendon were reliably healed Conclusions This operation gives reconstructed more fingers without sacrificing more toes for patients The walking function of donor foot is good The antigenicity of allogeneic grafts could be abated after preservation under 30℃ or frozen dried

Objective To define the indications of direct transpedicular lag screw to treat traumatic spondylolisthesis of axis (Hangmans fracure) and to evaluate the result of the technique. Methods From February 1998 to December 2000, 22 patients with acute traumatic spondylolisthesis of axis were treated. Ten of them achieved anatomic reduction by skull traction but no acceptable stability was ensured by traction alone. Among the ten patients, eight had integral and normal shaped C2 vertebral bodies (6 male, 2 female; age ranged from 18 to 42 years with an average of 28.2 years; 5, 2 and 1 patients classified as type Ⅰ, Ⅱ and Ⅱa injuries respectively according to Levine-Edwards classification and graded as D spinal injury in 2 cases and E in 6 cases according to Frankel scale) were further fixed with transpedicular lag screw. Under general anesthesia, the patients were laid in prostrate decubitus in a prepared head-neck-chest ventral plaster plate with skull traction in place to maintain reduction and lateral image intensification was applied to confirm the reduction. A posterior midline incision from C1-C3 was performed, and soft tissue was released to expose clearly the lamina, lateral mass, superior and medial aspect of the C2 pars interarticularis (isthmus plus pedicle). Points of entry for screw insertion were located at the entrance at the posterior aspect of lateral mass. The drill bit is parallel to both of the medial and superior border of C2 pars interarticularis (usually 25?-30? cephalad to the transverse plane and 30?-35? medial to the sagittal plane). The screw hole in the posterior cortex was overdrilled with a 3.5 mm drill bit for interfragmentary compression. 3.5 mm screws (25-30 mm, determined by depth gauge) were drived in after the cortex being tapped with a 3.5 mm tap. The whole procedure was done under monitoring of "C" arm fluoroscopy for safety and accuracy. Results It costs an average of 70 minutes to finish the procedure with mean blood loss of 250 ml. Hospital stay was about 18 days. A mean follow up time of 14 months (11 to 18 months) didnt confirm any early or late postoperative complications, all cases gained bony union 3 months later with complete neurological function recovery. The range of neck rotation was restored normal with no C2,3 instability or screw loosing found. Conclusion With appropriate indications, transpedicular lag screw fixation provides good reduction and stability to Hangmans fracture. This technique can only be applied to the fractures which are reductable.

Objective: To discuss the value of preserving ICBN during modified radical mastectomy for breast neoplasms. Methods: Sixty-three cases of breast carcinoma who underwent modified radical mastecto-my were studied. Of them, ICBN was completely preserved in 33 cases and was dissected in 30 cases. Sen-sory function of the medial upper arm of all patients was followed up after surgery. Results: No local recur-rence or metastasis was found among the 63 patients during the first, sixth, and twelveth month of follow-up period. Among the 33 cases with ICBN reserved, 29 cases (87.88%) had normal sensation of the skin in up-per medial arm and axilla, while 4 cases (12.12%) had paresthesia. Conclsion: Preserving ICBN can en-hance the quality of life of breast cancer patients after surgery.

Objective To establish a patient-like human ovary carcinoma/spontaneous metastasis model using orthotopic transplantation of histologically intact tumor tissue. Methods An highly metastatic ovarian tumor line (8910PM: human serum carcinoma of the ovary) previously grown substaneously was transplanted into the ovicapaule using microsurgery technique. Histologically intact human ovary tumor pieces gained from implantation site were passaged between ovicapsules for four generations. Results All mice developed ovary tumors and the metastatic rates were about 50 %. The tumors only metastasized to liver. The earliest appearance of metastasis was 14 days and the average survival period was 20.7 ±4.89 days. The microscopic appearance of the metastases was similar to the tumor observed in the substaneous xenografts and orthotopically transplanted.Chromosomes analysis exhibited the feature of human carcinoma and retained genetic stability during the processes of passage. Conclusion Orthotopic implantation provides a suitable micro-environment in which ovarian cancer can express its intrinsic clinically-relevant properties. This approach is relevant to the spontaneous development of ovarian cancer and is thought to be a useful model for studies of metastatic mechanism and therapy for ovary cancer.

This study was aimed to investigate the effect of modifiedYin-Chen-Hao (YCH) decoction on the expression of aquaporin-8 (AQP8) mRNA and protein in rats with estrogen-induced cholestasis, in order to explore the potential mechanism of YCH decoction in the treatment of intrahepatic cholestasis during pregnancy. A total of 50 SD female rats, which were weighed between 180 g to 200 g, were randomly divided into the normal group (N,n = 10) and the model group (M’,n = 40). The animal model of intrahepatic cholestasis was induced by subcutaneous injection of 17-α-ethinylestradiol (5 mg·kg-1·d-1) for 5 days of rats in M’ group. The same volume of propylene glycol was subcutaneously injected to rats in N group. Five days later, rats in M’ group were divided into the model group (M,n = 10), high-dose (Zg,n = 10), middle-dose (Zz,n = 10) and low-dose (Zd,n = 10) modified YCH decoction group. The intragastric administration of normal saline, high-dose, middle-dose and low-dose modified YCH decoction were given to each group for 7 days, respectively. Then, rats were sacrificed and the liver tissues were removed and stored in liquid nitrogen. The expression of AQP8 mRNA and protein were detected by real-time polymerase chain reaction (RT-PCR) and western blotting analysis. The results showed that compared with the normal group (N), the expression of AQP8 mRNA and protein in liver tissues of rats in the model group (M) were decreased (P < 0.01). Compared with the model group (M), the high-dose, middle-dose and low-dose modified YCH decoction can increase the expression of AQP8 mRNA and protein in liver tissues (P < 0.05). Moreover, along with the dose increasing of modified YCH decoction, the upregulation of AQP8 mRNA and protein was increased. It was concluded that the molecular mechanism of modified YCH decoction in treatment of intrahepatic cholestasis during pregnancy may be through the increasing of AQP8 mRNA and protein in liver tissues.

Objective To identify the crucial gene implicated in rheumatoid arthritis (RA) pathogenesis by comparing microarray-based gene expression profiles of synovial fibroblast in arthritis patients and that in control.Methods The public datasets were obtained from NCBI GEO and EBI ArrayExpress.The qualified microarray-based gene expression profiles were integrated and normalized using the method implemented in GeneSpring software.Furthermore,the differentially expressed genes (DEGs) were identified using significance analysis of microarrays (SAM) method.The online tool DAVID and STRING were applied to conduct the enrichment analysis and gene product interaction analysis respectively.Results There were two datasets that were qualified and analyzed in the present study.A total of 336 significant DEGs were identified by comparing the whole-genome gene expression profiles from synovial fibroblast of RA patients and control group.Among these DEGs,261 were significantly downregulated and 75 upregulated.About 13.6％ of the downregulated genes were associated with extracellular matrix degradation.The COL9A3 and COL4A5,indispensable component of hyaline cartilage and basement membrane respectively,were significantly downregulated,as well as genes in WNT family,including WNT2,WNT11,and WNT16.In contrast,matrix metalloproteinase 13 (MMP13) was found to be significantly upregulated in RA patients.MMP13 is a matrix metallopeptidase that degrade extracellular matrix and hyaline cartilage,and it could possibly interact with other proteins to regulate morphogenesis.Conclusion Molecular mechanisms underlying RA pathogenesis were investigated by analyzing the public datasets.A few genes that associated with extracellular matrix degradation,construction and regulation,including MMP13,WNT2,WNT11,WNT16,COL9A3 and COL4A5,could be regarded as therapeutic targets in RA treatment.
