OBJECTIVETo observe the levels of high mobility group box-1 protein (HMGB1), tumor necrosis factor-alpha (TNF-α), IL-6, troponin I (Tn I) release in septic rats, and to explore themechanism of Taohong Qinlian Decoction (TQD) in the treatment of septic myocardial injury.
METHODSA total of 48 healthy male Wistar rats of clean grade were randomly divided into the sham-operation group (Sham), the sepsis model group (CLP), and the TQD treatment group (ZY), 16 in each group. Concen-trations of TNF-α, IL-6, Tn I, and HMGB1 expression were detected in each group at 24 and 48 h after operation. Pathological changes of cardiac muscle were observed under light microscope.
RESULTSConcentrations of TNF-α, IL-6, Tn I and HMGB1 at 24 and 48 h after operation were significantly higher in the CLP group than in the Sham group (P < 0.01). Concentrations of TNF-α, IL-6, Tn I, and HMGB1 at 24 and 48 h after operation were significantly lower in the ZY group than in the CLP group (P < 0.05). Myocardial injury occurred in the CLP and the ZY group under light microscope. And this injury was more severe in the CLP group than in the ZY group.
CONCLUSIONTQL could reduce the level of sepsis-related inflammatory cytokines and protect myocardium in septic rats.

OBJECTIVETo evaluate the outcome of Titanium elastic intramedullary nailing (TEN) for the treatment of displaced midclavicular fractures.
METHODSBetween February 2010 and February 2013, 62 patients with displaced midclavicular fractures were treated by TEN, including 27 males and 35 females with an average age of 37.6 years old ranging from 15 to 67 years. The course of disease was from 1 to 9 days (means 2.7 days). Thirty-nine cases were treated by closed reduction and 23 cases by assistant small incision. Based on OTA (the Orthopaedic Trauma Association classification) classification, 31 cases of simple fractures involved 5 cases of 06-A1,15 cases of 06-A2,11 cases of 06-A3; 31 cases of wedge fractures involved 4 cases of 06-B1,12 cases of 06-B2,15 cases of 06-B3. Postoperative pain relief were evaluated by VAS score,and operation time,fracture healing time were recorded. After 6 weeks and after removing internal fixation shoulder joint function was evaluated by Constant score, and shoulder joint function were assessed by Herscovici score after 6 weeks.
RESULTSExcept 2 cases were lost to follow-up, 2 cases did not remove internal fixation, 3 cases' fractures were nonunion, the remaining 55 patients received follow-up for an average time of 11.4 months. The average preoperative VAS score was 5.20±0.71, and it turned to be 1.550.59 at 3 days after operation. The average operative duration was 40 min (15 to 65 min). The average bone healing time was (2.71±0.54) months (2 to 5 months). No difference about bone healing time was found between simple fractures and wedge fractures,and between the patients treated by closed reduction and assistant small incision. According to Herscovici standard, the shoulder function was excellent in 49 cases, good in 4, fair in 1, and poor in 1. Simple fractures achieved better Constant score than wedge fractures at 6 weeks postoperatively, whereas no difference was found at 4 weeks after fixation removal.
CONCLUSIONTitanium elastic nails (TEN) for treatment of displaced midclavicular fractures has advantages of good clinical effect,rapid pain relief,fast recovery of shoulder joint function. For OTA classification type B patients with comminuted fracture can replace steel to achieve very good effect, but to grasp the appropriate.

OBJECTIVETo study the effect of Tongluo Xingnao effervescent tablets on learning and memory capacity and expression of Na(+)-K(+)-ATPase in hippocampus of rats with chronic cerebral ischemia-induced learning and memory dysfunction model.
METHODThe 2-VO method was used to establish sd rat model learning and memory dysfunction induced by chronic cerebral ischemia. The 50 rats in the successfully established model were randomly divided into the model control group, the Dihydroergotoxine Mesylate tablets group (0.7 mg x kg(-1), Tongluo Xingnao effervescent tablets high dose (7.56 g x kg(-1)), middle dose (3.78 g x kg(-1)) and low dose (1.59 g x kg(-1)) groups and the sham operation group (n = 10) as the control group. The groups were orally given 10 ml x kg(-1) x d(-1) drugs for consecutively 90 days. On the 86th day, Morris water maze was adopted for them. On the 90th day, a leaning and memory capacity test was held. The brain tissues were fixed with 10% formaldehyde and observed for pathomorphism after routine slide preparation and staining. The expression of hippocampal Na(+)-K(+)-ATPase was detected with immunohistochemistry and image quantitative analysis.
RESULTCompared with the model group, all of Tongluo Xingnao effervescent tablets groups showed significant decrease in the escape latency at the 5th day in the Morris water maze, and notable increase in the frequency of the first quadrant dwell, the frequency passing the escape platform and the frequency entering effective area (p < 0.05). According to the pathomorphological detection, the control group showed a significantly higher pathological score than the sham operation group (p < 0.01), the middle dose group showed a significantly lower pathological score than the model group (p < 0.05). According to the immunohistochemistical detection, the model control group showed a remarkably lower mean OD value of Na(+)-K(+)-ATPase than the sham operation group (p < 0.05), high and middle dose groups showed a significantly higher mean od value than the model control group (p < 0.01).
CONCLUSIONTongluo Xingnao effervescent tablets can improve the learning and memory capacity, reduce pathological changes of hippocampal tissues of rats with chronic cerebral ischemia-induced learning and memory dysfunction model, and promote the expression of Na(+)-K(+)-ATPase in hippocampus.

OBJECTIVETo investigate the association between the morphological features of biopsy-diagnosed high grade intraepithelial neoplasia in the gastric mucosa and the postoperative pathology.
METHODSFifty-one patients with biopsy-diagnosed high grade intraepithelial neoplasia in the gastric mucosa were retrospectively analyzed. Thirty-three patients underwent surgery. The morphology of lesions under endoscopy and histopathological findings of the surgical specimens were investigated.
RESULTSOf the 51 patients, 43 had superficial lesions similar to early gastric cancer under endoscopy, 8 were similar to advanced carcinoma. In the 33 surgical cases, high grade intraepithelial neoplasia of gastric mucosa was confirmed on postoperative pathological examination in 13 (39.4%) patients, adenocarcinoma was identified in the remaining 20 patients (60.6%), including 14 early gastric cancers and 6 advanced carcinomas. Thirteen cases with high grade intraepithelial neoplasia confirmed postoperatively were superficial elevated or flat lesions less than 20 mm.
CONCLUSIONSPatients with biopsy-diagnosed high grade intraepithelial neoplasia in the gastric mucosa have a high risk of cancer. Thus aggressive follow-up and appropriate surgical interventions are recommended to avoid misdiagnosis.

OBJECTIVETo compare the effects of puerarin and granulocyte colony-stimulating factor (G-CSF) in treating acute myocardial infarction (AMI) and on the size of infarcted area and cytokines.
METHODSSeventy-nine patients with anterior AMI were randomly divided into three groups, they were treated with conventional Western medical treatment, but to the puerarin group (PG) and the G-CSF group (GCG) puerarin and G-CSF was given additionally, respectively. The infarcted size, plasma G-CSF, matrix metalloproteinase-9 (MMP-9), serum interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) were detected before and after treatment.
RESULTSThe infarcted size was positively correlated to the levels of G-CSF, MMP-9, IL-6 and TNF-alpha before treatment ( r = 0.45, 0.42, 0.44 and 0.42, P<0.01 ). The infarcted size in the PG and the GCG decreased on the 28th day (P<0.01), the level of G-CSF, MMP-9, IL-6 and TNF-alpha in the PG on the 7th day all decreased (P<0.05), but these indexes in the GCG increased (P<0.05), while those in the control group were unchanged (P>0.05).
CONCLUSIONPuerarin and G-CSF are effective in decreasing infarcted size, but their effects on cytokines are different entirely.

OBJECTIVETo observe the clinical effects of combined type external fixator in treating complex tibial metaphyseal fractures.
METHODSFrom January 2007 to July 2012, 34 patients with complex tibial metaphyseal fractures were treated with combined type external fixator in different stagings. There were 23 males and 11 females, with a mean age of 41.3 years (ranged, 16 to 63), and the course of disease were from 1 h to 8 d. In the patients, 31 cases were open fractures, 11 cases with type II, 13 cases with type III A, 7 cases with type III B according with Gustilo classification; 19 cases were tibia plateau fractures, 6 cases with type II, 1 case with type IV, 5 cases with type V, 7 cases with type VI according to Schatzker classification; 15 cases were distal tibial fractures (one were bilateral fractures), 2 fractures with type A2, 1 fracture with type A3, 1 fracture with type C1, 5 fractures with type C2, 7 fractures with type C3 according to AO classification. Rasmussensn scoring system and AOFAS Ankle Hind-foot Scale were respectively used to assess the joint function of knee and hip.
RESULTSWound surface of 19 patients obtained at phase I healing and 15 patients obtained at phase III healing. Superficial wound infections occurred in 2 cases and bone non-union necessitated reoperation occurred in 2 cases (final fractures obtained bone healing after the second operation). All patients were followed up from 6 to 38 months with a mean of 14.3 months. At the final follow-up,according to Rasmussensn scoring system, 5 fractures got excellent results, 11 good, 3 fair, the mean Rasmussen score was 23.58 +/- 3.98; according to AOFAS Ankle Hind-foot Scale, 5 fractures got excellent results, 8 good, 3 fair, the mean AOFAS Ankle Hind -foot Scale was 80.75 +/- 14.21.
CONCLUSIONCombined type external fixator can well maintain the stability of the fractures, had advantages of low incidences of soft tissue complications and less influence to joint motion in treatment of complicated tibial metaphyseal fractures. However there were some limitations in long-term use.

OBJECTIVECase-control study was employed to explore the association of sexual behavior during pregnancy and hepatitis B virus (HBV) intrauterine infection.
METHODS212 HBsAg positive pregnant women were consecutively collected and investigated as objects. Those neonates detected for HBsAg with S/N value > or = 5 by Abbott reagents in periphery sera were selected as cases, others as controls. Information on sexual behavior during pregnancy, maternal HBeAg status and other factors was collected, and were analyzed with univariate analysis, multivariate logistic regression analysis, etc, to explore the association of factors with HBV intrauterine infection.
RESULTSTen of the 214 neonates were validated as occurrence of HBV intrauterine infection. Sexual behavior in the second trimester during pregnancy, with odd ratios 9.15 (95% CI: 1.10 - 76.28), as well as maternal positivity for HBeAg and HBV DNA, was significantly associated with HBV intrauterine infection, and sequently affirmed by multiple logistic regression analysis. The strength of association increased with frequency of sexual behavior. Interaction analysis suggested that there was synergistic interaction between maternal positivity of HBeAg and sexual behavior in the second trimester.
CONCLUSIONSexual behavior was a newly discovered risk factor for HBV intrauterine infection, which need to be estimated in future studies. Inhibition of virus replication and moderate control of sexual behavior would be helpful to prevent HBV intrauterine infection.
