To observe the curative effect and the hemodynamic change of cervical vertigo treated by acupuncture, 66 patients were randomly divided into two groups: group A in which acupoints Yuzhen (BL 9) and Fengchi (GB 20) were used and Group B in which Cervical Jiaji points (C4-6) were used. Before and after treatment, the symptom of the cervical vertigo and the grade variety of function and the change of Color Doppler Flow Imaging (CDFI) of vertebral artery were observed. After treatment, the grade in two groups increased, there was a remarkable difference between two groups(P ＜ 0.05); after treatment, the grade of vertigo degree increased, there was a remarkable difference between two groups(P ＜ 0.05); needling Yuzhen (BL 9) and Fengchi (GB 20) can remarkably improve the symptom of cervical vertigo and vertebral artery blood flow rate, and the curative effect was superior to needling Jiaji points.

OBJECTIVE: To study the mechanism of herbal application along meridians for treatment and prevention of asthma by using serum pharmacological test to observe the effects of serum containing herbs against the constriction of tracheal spiral strips induced by acetylcholine chloride (Ach). METHODS: Guinea pigs were randomly divided into normal control group, normal saline (NS) application group, aminophylline application group, aminophylline injection group, 1-day herb application group, 7-day herb application group and 14-day herb application group. Asthma was induced by Hutson's method in guinea pigs except the normal control group. Guinea pigs in herb application groups were treated by external application of a compound herbal medicine 60 min once every day. Guinea pigs in NS application group were treated by external application of NS. Guinea pigs in the two aminophylline-treated groups were treated by external application and intraperitoneal injection of aminophylline at a dose of 400 mg/kg, respectively. The guinea pigs were killed and the sera were obtained after 1-day, 7-day and 14-day treatment in the three herb application groups, 7-day treatment in the NS application group, the aminophylline application and injection groups, respectively. Serum pharmacological method was used to do the experiment, the effects of different sera on the constriction of tracheal strips were observed, and the constriction rates were calculated. RESULT: The serum containing herbs had an effect in reducing the constriction of tracheal spiral strips induced by Ach, and the effect was similar to that of the serum obtained from the aminophylline injection group. The constriction rate of the tracheal spiral strips was decreased when herbal application treatment was prolonged within a period of time, and it became stable when herbal application treatment was between 7-14 days. The constriction of tracheal spiral strips induced by Ach could be reduced remarkably when it was previously treated by serum containing herbs. CONCLUSION: The anti-acetylcholine function with a time-dependent effect is one of the mechanisms of herbal application treatment along meridians for asthma, and furthermore, herbal application treatment along meridians might be useful for preventing asthma.

Objective To assess the value of salivary gland scintigraphy in diagnosis of Sj(o)gren's syndrome (SS).Methods A total of 44 patients with clinically suspicious SS were included.The data of salivary gland scintigraphy were retrospectively analyzed and the time-radioactivity curve (TAC) was obtained by outlining ROI in bilateral parotid glands and submaxillary glands.Uptake index (UI) and excretion fraction (EF) were defined.Both UI and EF were compared with the visual assessment and final diagnosis respectively.Results UI and EF of bilateral parotid glands and submaxillary glands in SS patients were significantly lower than those in non-SS patients (all P＜0.05).The impaired salivary gland function was classified as 0-3 grades by visual assessment.The UI of bilateral parotid glands and submaxillary glands were negatively correlated with the qualitative classification.While there were no significant correlations between EF and qualitative classification (all P＞0.05),except for that of right submaxillary gland (r=-0.312,P=0.039).The comprehensive diagnostic efficacy of UI on SS patients was higher than those of visual assessment,but their area under curves of ROC were not significantly different (all P＞0.05).Conclusion UI and EF can effectively evaluate salivary gland function and serve as objective tools to distinguish patients with SS.

The purpose of this study was to construct expression vectors of idiotype (Id) SmIg in patients with B-chronic lymphocytic leukemia and to express them in E.coli to obtain recombinant Id, and to investigate the effect of the protein on the proliferation and secretion of IL-2 and IFN-gamma of stimulated peripheral blood mononuclear cells (PBMC) in vitro. Light chain gene and Fd fragment of heavy chain gene were inserted into fd-tet-DOG2 vector to construct fd-tet-DOG2-Fab. Fab gene was further cloned into expression vector pHEN2 to construct the soluble expression vector pHEN2-Fab. After induction by IPTG, Fab protein was purified by Ni-NTA-chromatography. MTT was used to determine the effects of purified protein on the proliferation of stimulated PBMC in vitro and the concentrations of IL-2 and IFN-gamma in the culture supernatants were detected by ELISA. The results showed that recombinant pHEN2-Fab expression vector was constructed successfully. Fab protein was expressed in positive clone after induced by IPTG and two specific bands at 24-25 kD position were observed by SDS-PAGE electrophoresis. Proliferation of PBMC could be induced by purified Fab and the concentrations of IL-2 and IFN-gamma in culture supernatants were increased significantly after induction. It was suggested that the expression vector of SmIg Fab fragment was constructed successfully, and expressed and secreted from E. coli. The Fab protein could induce proliferation of PBMC and promote secretion of IL-2 and IFN-gamma.

OBJECTIVE: To assess the relationship between the prognosis of the patients with diffuse traumatic brain swelling (DTBS) and the changes of the ventricles and the cisterns in CT scans. METHODS: The outcome of the patients with DTBS and the changes of the ventricles and the cisterns in CT scans were studied and analyzed in a group of 268 cases. We focused on the changes of the third ventricle and the basal cistern, age and Glasgow Coma Scale (GCS). RESULTS: Of 268 cases, there were changes of the third ventricle and/or the basal cistern in 124, 65 died. In l8 cases, the third ventricle and the basal cistern were both absent and l6 died (88.9%). The third ventricle changed significantly in 59 cases, 33 died (55.9%), while the basal cistern changed in 47 cases and 16 died (34%). Of the 124 patients with changes of the third ventricle and/or the basal cistern, 26 were children, 8 died; 98 adults, 57 died. CONCLUSIONS: For patients with DTBS, the outcome was in direct correlation with the change of the third ventricle and/or the basal cistern, the change of the third ventricle was much more important in assessment of the outcome than that of basal cisterns. There is no significant difference in, the incidence of DTBS between children and adults while the outcome of children is much better than that of adults. The patients with the changes of the third ventricle and the basal cistern accompanied with lower GCS scores have poor outcome.

Background and purpose: Radiofrequency ablation (RFA) is one of the effective treatment methods for primary liver cancer and metastatic liver cancer. The purpose of this study was to investigate the risk factors of residual tumor after RFA for hepatic malignancies. Methods:A total number of 302 hepatic malignancies cases with 691 tumors after ultrasound-guided RFA from Jan. 2010 to Mar. 2013 were retrospectively analyzed. Single factor and multi-factor Logistic regression model were used to analyze the risk factors of residual tumor after RFA. Results:Complete ablation cases were 90.07%(272/302) for patients and 91.46%(632/691) for tumors, and the ablation residual rate was 8.54%. Ablation residual rates for tumor ≤3 cm, 3-5 cm and >5 cm in diameter were 6.30%, 9.57% and 28.57%, for tumor close to the intrahepatic vascular and gallbladder were 17.14%and 18.52%, for with and without combination with other local treatments were 7.02%and 13.41%, respectively. Multivariate analysis showed that tumor size>5 cm (P=0.044), proximity to large vessel (P=0.039) and without combination with other local treatments (P=0.001) were independent risk factors for ablation residual. Multivariate analysis showed that tumor near the intrahepatic vascular (P=0.014), single needle RFA (P=0.047) and without combination with other local treatments (P=0.023) were independent ablation residua risk factors for tumors between 3-5 cm in maximum diameter. Conclusion:Ultrasound-guided RFA can achieve satisfactory ablation effect. Tumor close to the intrahepatic vascular, tumor diameter>5 cm and without combination with other local treatment act as the independent risk factors for ablation residual. For tumors between 3-5 cm in diameter, in addition to close to intrahepatic blood vessels and without combination with other local treatment, single needle RFA is also another independent risk factor for ablation residual, and double-needle or multi-needle treatment can improve the ablation efifciency and reduce residual rate.

Methods Field investigation was conducted in the suburb of Shanghai City by screening the mobile population living in Shanghai for more than 1 month and over 1 years old in a procedure of interviewing, serum indirect hemagglutination (IHA) test, and then fecal examination to detect the eggs with nylon sedimentation approach for those IHA positives. Results Among 2 931 mobile people investigated, 1 575 were male (53.74%) and 1 356 were female(46.26%); 138 out of 2 931 were positive in IHA test (4.71%). 1 938 (66.12%) out of 2 931 came from Schistosoma japonicum-endemic provinces and its positive rate in mobile population (5.99%) was significantly higher than those from the transmission-interrupted provinces (2.6%) (?2=10.28, P

OBJECTIVETo evaluate the feasibility of lymphoscintigraphy in sentinel lymph node biopsy of breast cancer.

METHODLymphoscintigraphy was performed after peritumoral or subdermal injection of radioactive colloid. Then, sentinel lymph node (SLN) biopsy guided by gamma detector probe was performed. Factors correlated with identification-detection rate were assessed.

RESULTSLymphatic drainage was present in preoperative lymphoscintigraphy in 88(93%) out of 95 patients, with 39 (44.3%) positive for lymphatic drainage other than in the axilla. A total of 91 (95.8%) patients had their SLN identified in the intraoperative procedure. The quality of lymphoscintigraphic image was closely related to SLN identification-detection rate in the intraoperative procedure (P = 0.025).

CONCLUSIONSentinel lymph node outside the axilla can be detected by lymphoscintigraphy. The combination of lymphoscintigraphy and gamma detector probe for sentinel lymph node biopsy of breast cancer not only is acceptable but promising.
