OBJECTIVETo explore the effects of integrative medicine (IM) rehabilitation protocolon motor function, activity of daily living, and quality of life (QOL) in hemiplegia patients after stroke.

METHODSTotally 120 patients with post-stroke hemiplegia were allocated to four groups using sealed envalope drawing, i.e., the rehabilitation group, the Chinese medical treatment group, the acupuncture group, and the comprehensive rehabilitation group, 30 cases in each group. Based on routine rehabilitative training, patients in the Chinese medical treatment group, the acupuncture group, and the compre-hensive rehabilitation group received standardized treatment based on syndrome typing, Shi's Consciousness-Restoring Resuscitation acupuncture, Chinese herbs + acupuncture comprehensive rehabilitatino protocol, respectively. The treatmet cycle consisted of 4 weeks with 24-week follow-ups. Fugl-Meyer motor assessment (FMA), Modified Barthel Index (MBI), and Stroke-Specific Quality of Life Scale(SS-QQL), and safety assessment were taken as main effect indices before treatment, at week 4 of treatment, at week 12 and 24 of follow-ups, respectively.

RESULTSThere was no statistical difference in FMA score, MBI score, SS-QOL score among the four groups before treatment (P > 0.05). These scores were significantly improved in the four groups at week 4 of treatment, week 12 and 24 of follow-ups, respectively (P < 0.05). Besides, FMA score and SS-QOL score were significantly improved in the comprehensive rehabilitation group at each corresponding time point, as compared with other treatment groups (P < 0.05).

CONCLUSIONSThe comprehensive protocol could significantly improve motor function, activity of daily living in hemiplegia patients after stroke, and further improve their QOL. Its effect was better than other single treatment.

OBJECTIVETo compared the effect between early anatomical open reduction, internal fixation (ORIF) and closed reduction, internal fixation (CRIF) for treatment of children displaced femoral neck fracture.

METHODSFrom March 2006 to May 2010,34 children with displaced femoral neck fractures were reviewed retrospectively. These patients were divided into two groups. Among them, 19 cases were treated by open reduction and internal fixation (ORIF) as group A, included 11 males and 8 females with an average age of (8.1 +/- 1.3), the other 15 cases were treated by closed reduction and internal fixation (CRIF) as group B, included 9 males and 6 females with an average age of (7.9 +/- 1.5). Complications were observed and the short term effectiveness was evaluated by Ratliff standard.

RESULTSAll children were followed-up from 1 to 3 years (means 1.2 years). All fractures were healed. There was statistical different in the curative effects between the two groups (Z=2.389, P= 0.017). The incidence of complications in two groups had statistical different (P=0.046).

CONCLUSIONThe early ORIF could get better reduction with fewer complications than CRIF in fractures of the displaced femoral neck in children in Delbet type-II and type-III, therefore, ORIF should be considered.

OBJECTIVETo prepare polyelectrolyte multilayer film-coated microbubble ultrasound contrast agent (UCA) and evaluate its effects in contrast imaging on normal rabbit's liver parenchyma.

METHODSPerfluorocarbon (PFC) -containing microbubble UCA (ST68-PFC) were prepared by sonication-based on surfactants (Span 60 and Tween 80). Subsequently, the resulting ST68-PFC microbubbles were coated using oppositely charged polylysine (PLL) and alginate (Alg) by microbubble-templated layer-by-layer self-assembly technique via electrostatic interaction. The enhancement effects in contrast imaging on normal rabbit's liver parenchyma were assessed.

RESULTSThe obtained microbubble UCA exhibited a narrow size distribution. The polyelectrolytes were successfully assembled onto the surface of ST68-PFC microbubbles. In vivo experiment showed that polyelectrolyte multilayer film-coated UCA effectively enhanced the imaging of rabbit's liver parenchyma.

CONCLUSIONSThe novel microbubble UCA obtained via layer-by-layer self-assembly, when enabling more functions, has no obvious difference in enhancement effects compared with the premodified microbubbles. The polymers with chemically active groups (such as amino group and carboxyl group) can be used as the outermost layer for the attachment of targeting ligands to microbubbles, which allows the selective targeting of the microbubbles to desired sites.

OBJECTIVETo evaluate the efficacy and side effects of combined Chinese drugs and chemotherapy in treating advanced non-small cell lung cancer (NSCLC).

METHODSSixty-three patients with stage III B and IV NSCLC hospitalized from October 2001 to October 2008 were enrolled and assigned to two groups using a randomizing digital table, with 33 patients in the treatment group and 30 in the control group. They were all treated with the Navelbine and Cisplatin (NP) chemotherapy, but to the treatment group the Chinese drugs Shengmai Injection () by intravenous dripping and Gujin Granule () by oral intake were given additionally. The main observation indexes were response rate (RR), median survival time, 1-year survival rate and median time to progression (TTP); secondary observation indexes were side effects and cycles of chemotherapy.

RESULTSAltogether, 61 patients (33 from the treatment group and 28 from the control group) completed the observation and were assessable. RR was 48.5% (16/33) in the treatment group and 32.2% (9/28) in the control group, and the median survival time were 13 months and 9 months, respectively; the difference between the two groups was significant (P=0.0373 and P=0.014 respectively). However, the differences between groups were insignificant in terms of 1-year survival rate [51.5% (17/33) vs 46.4% (13/28), P=0.4042], median TTP (5.95 months vs 4.64 months, P=0.3242), grade III or IV bone marrow inhibition occurrence rate [33.3% (11/33) vs 39.3% (11/28), P=0.3500], and mean cycles of chemotherapy applied (2.94+/-0.94 cycles vs 2.75+/-0.75 cycles, P=0.4100).

CONCLUSIONCombined Chinese drugs and chemotherapy can enhance the short-term therapeutic efficacy in the treatment of NSCLC and prolong patients' median survival time, but show no evident impact on TTP.

OBJECTIVETo generate hepatitis C virus pseudo-particles (HCVpp) containing the complete E1-E2 envelope glycoprotein, in order to establish a HCVpp database covering the six major genotypes of HCV (1b, 2a, 3b, 4, 5, and 6) and to develop a simple and effective method for detection of neutralizing antibodies in HCV patients.

METHODSHCVpp were generated for the six genotypes by co-transfecting 293T cells with a plasmid expressing the respective E1-E2 (p HR, CMVA 8.2 construct) and a MLV-GFP plasmid. Titration of each HCVpp was carried out by p24 ELISA. Infectivity of each HCVpp was assessed by mixing the harvested supernatant of producer cells with sera from HCV patients, adding the mixture to Huh-7 cells, and detecting the subsequent titers of neutralizing antibodies against HCVpp.

RESULTSAll six types of HCVpp were able to infect Huh-7 cells in vitro. For healthy HCV carriers, only two genotypes of HCVpp (1b and 2a) produced neutralizing antibody titers more than 1:40. For cured HCV patients, only the 1b genotype produced neutralizing antibody titers more than 1:40. One patient showed titer of 1:200 for genotype 4. A healthy spouse of a chronic hepatitis C patient showed titers more than 1:40 for four genotypes of HCVpp (3a, 4, 5, 6).

CONCLUSIONWe generated six different genotypes of HCVpp successfully, established the in vitro neutralizing antibody detection method, and provided an effective model for screening antiviral drugs.

OBJECTIVETo compare the effects and pharmacoeconomics of single-dose of ceftriaxone versus 3-day cefuroxime prophylaxis in patients undergoing gastric or colorectal resection.

METHODSThree hundred and five consecutive patients with gastric or colorectal cancer from 5 medical centers were randomly divided into ceftriaxone group (n = 153, receiving intravenously 1 g ceftriaxone 0.5 - 1 h prior to operation only) and cefuroxime group (n = 152, receiving 0.75 g cefuroxime preoperatively and the same dose q8h for 3 d). The patients' intra- and postoperative status, adverse responses and infectious complications were observed and documented, and pharmacoeconomic parameters were analyzed.

RESULTSThe disease distribution, operative procedures and patients' conditions in the 2 groups were comparable. No adverse responses to the test antibiotics were observed. Postoperative infectious complications occurred in 7 cases in the ceftriaxone group (4.58%) and 14 cases in the cefuroxime group (9.21%), respectively (P = 0.992), among which, 12 cases were surgical site infections (incisional, intra-abdominal): 2 cases in the ceftriaxone group (1.31%), and 10 cases in the cefuroxime group (6.58%), (chi(2) = 5.607, P = 0.018). The direct cost related to prevention and treatment of surgical site infections was 283.5 RMB in the ceftriaxone group and 811.1 RMB in the cefuroxime group (Z = 14.51, P = 0.000).

CONCLUSIONBoth ceftriaxone and cefuroxime are safe and effective for prevention of surgical site infections. Single-dose ceftriaxone prophylaxis is sufficient for gastric and colorectal operations, with a better cost-effectiveness ratio.

OBJECTIVELyme disease and Human granulocytic anaplasmosis are tick-borne diseases caused by Borrelia burgdorferi and Anaplasma phagocytophilum respectively. We have investigated infection and co-infection of the two diseases in the population of forest areas of eight provinces in China by measuring seroprevalence of antibodies against B. burgdorferi and A. phagocytophilum.

METHODSForest areas in 8 provinces were chosen for investigation using whole sampling and questionnaire survey methods. 3 669 serum samples from people in the forest areas were tested for the presence of antibodies by indirect immunofluorescent assay (IFA).

RESULTSSeroprevalence against B. burgdorferi was 3% to 15% and against A. phagocytophilum was 2% to 18% in the study sites in the 8 provinces in China. We also found co-infection of B. burgdorferi and A. phagocytophilum in 7 of the 8 provinces (the exception being the Miyun area in Beijing). The seroprevalence for both B. burgdorferi and A. phagocytophilum was significantly higher among people exposed to ticks than among people who were not exposed to ticks.

CONCLUSIONWe conclude that both pathogens are endemic in the forest areas in the eight provinces, but the prevalence of B. burgdorferi and A. phagocytophilum differs between the provinces.

Objective To study the first locally identifcd A/HINI secondary cases outbreak in China. Methods Interview and field investigation were integrated to describe the whole process of transmission on each case and to illustrate the relationships between the onset of the disease and the retated factors. Results Two contact persons appearanced fever and whose throat swabs were tested positive to H1N1 viral nucleic acid. The two had a history of contact in a short distance with the initial imported case without any protective measure in the poor air ventilation. The patients clinical situation was slight. The incubation was between 37 hours and 57 hours. No other new case was found after intervention as isolation and antisepsis were taken. Conclusion This event was proved to be an outbreak of local A/H1N1 secondary cases caused by the imported case. The main mode of transmission was personal contact in a short distance without protection, through air and droplet. The locus with poor air ventilation was high risk place. Contact persons should be observed seven days and tested continuously.Infectivity and pathogenicity of the A/H1N1 virus were limited and appeared weakened by generations. Patient's condition was related with persistence and frequency of contact with the infection sources. Enhancing management of contact persons, health education, early diagnose, early treatment and early insulation were effective measures of controling and prenventing the spread A/H1N1.

OBJECTIVETo evaluate the efficacy and safety of postoperative adjuvant chemotherapy with imatinib in gastrointestinal stromal tumor(GIST) patients who had high risk of recurrence.

METHODSA prospective, open-label, multi-center trial conducted in sixteen teaching hospitals in China was carried out. The criteria of the enrolled patients included age more than 18 years old, CD117 positive GIST, tumor size more than 5 cm, pathological mitosis counts more than 5/50 HPF, and treatment beginning within 4 weeks after complete resection and with imatinib (400 mg, once a day) for at least 12 months. The 1, 3 year recurrence rates, disease free survival, overall survival rate and quality of life were evaluated.

RESULTSFrom Aug. 16th 2004 to Sep. 13th 2005, there were totally 74 patients screened and 57 patients (34 men, 23 women) enrolled in the imatinib treatment group. The primary tumors were located in the stomach in 50.9%, the small intestine in 38.6% and the colorectum in 10.5% of the cases. All the patients received radical resection. Until the cut-off date of interim analysis, there was no evidence of tumor relapse or metastasis in all patients and no death was reported either. Among the 57 enrolled patients with intention to treat(ITT), twelve patients finished the protocol (per protocol, PP). The disease free survival was (268.3 +/-120.2) d in ITT analysis, and (396.7+/-38.2) d in the PP analysis. The incidence of adverse effect was 44.4% . The score in quality of life showed no statistically significant difference between the baseline visit and the follow-up visits.

CONCLUSIONImatinib is a promising postoperative adjuvant chemotherapy in GISTs patients with high risk of recurrence, and the adverse effects are receivable.
