Helicobacter pylori(Hp) is an important pathogenic factor in chronic gastritis,peptic ulcer and gastric cancer.With the extensive use of broad-spectrum atibiotics in recent years,the antibiotic resistence of Hp was increasing,together with many side effets and low patient compliance,so the study of new anti-Hp drugs became a research hotspot.Domestic and foreign scholars had extracted active anti-Hp ingredients from the traditional Chinese drug curcuma,they hope to open a new way for the treatment of Hp infection.This paper was to make a brief overview on the study progress of effect of curcuma on anti-Hp.

Objective To analyze the outcome of applying venous flow-through flap in replantation of complex severed finger.Methods From March,2011 to August,2012,15 cases of complex severed fingers were repaired by flow-through flap with two sets of venous system of forearm vein and one stage repair of wound.The time from injury to operation was 1.5-5.5 h (mean 2.5 h).Vascular defect length ranged from 1.5 to 11.0 cm (mean 3.6 cm);and soft tissue defect of 1.5 cm × 3.0 cm to 11.0 cm × 11.0 cm.All digits had severe soft tissue defect and segmental defect of blood vessels.All the finger blood circulation was disorder.Results All flaps and replanted fingers survived completely,except 1 case of postoperative venous crisis occurred which was remission after the vascular transplantation,and 1 case of skin flap necrosis at the distal part which was healed after skin grafting; Fourteen cases were followed-up from 7 to 20 months.At the final followed-up the flaps were of good consistency and appearance.Function of the finger was graded excellent in 7 cases,good in 5 cases,and poor in 2 cases.All flaps and replanted fingers survived completely over a period of 12 to 30 months follow-up.The flaps were of good consistency and appearance.Function of the finger was graded excellent in 7 cases and good in 5 cases.Conclusion With less injury at donor site,and good repair results,venous flow-through flap is well indicated in complex finger replantation with soft tissue defect and vascule defect.

OBJECTIVETo explore clinical characteristics and treatment of posterior Pilon fracture.

METHODSFrom January 2011 to January 2013,18 patients with posterior Pilon fracures were treated. Among them, 13 were male and 5 were female, aged from 22 to 63 years old, with an average age of 46. All the patients were closed fractures. Open reduction and internal fixation were performed after swelling subsided, lateral malleolous and posterior Pilon fracture were exposured through lateral approach on healthy side, plates were used to fixed,screws or small plates were used to fix the posterior prominence of medial malleolus after changed to supine position. AOFAS scoring were applied to evaulate clinical effects.

RESULTSAll patients were followed up with an average of 22(ranged, 12 to 48)months. All patients obtained satisfactory reset except one patient. All factures were recovered well with an average healing of 11 weeks. According to AOFAS score at the final following up, 7 cases were excellent,2 cases were moderate, and the total score was 86.8±9.2.

CONCLUSIONPosterior Pilon fracture is not rare in clinical, its mechanism of injury, traumatic anatomy, surgical procedure and prognosis are different from that of classical ankle fracture and Pilon fracture.

BACKGROUND:Atopic individuals predispose to alergic rhinitis after contacting with an alergen, which is mainly released by IgE-mediated histamine. Alergic rhinitis is a kind of non-infectious inflammatory disease that involves a variety of immune cels and cytokines and is related to Th1 and Th2 immune imbalance. Interferon γ is a cytokine secreted by Th1 cels, while interleukin-4 is a cytokine secreted by Th2 cels. OBJECTIVE:To establish a stable 129Sv mouse model of alergic rhinitis, so as to lay the foundation of establishing gene knockout 129Sv mouse models of alergic rhinitis, and to observe the concentration variation of IgE, interleukin-4 and interferon γ. METHODS: Twenty-four mice were randomly divided into 2 groups: model and control groups. Mice in the model group were sensitized by intraperitoneal injection of ovalbumin to establish mouse models of alergic rhinitis. Mice in the control group were subjected to intraperitoneal injection of PBS. After successful modeling, pathological changes of nasal eosinophils and plasmocyte infiltration were evaluated by nasal mucosa staining. Interleukin 4 and interferon γ levels and ovalbumin-specific IgE antibody concentration were detected by enzyme-linked immunosorbent assay. RESULTS AND CONCLUSION:Enzyme-linked immunosorbent assay showed that compared with the control group, serum ovalbumin-IgE and interleukin-4 concentrations were significantly increased, and Interferon γ concentration was significantly lower in the model group (P < 0.05). Hematoxylin-eosin staining results showed that cilia lodging and submucosal serous gland hyperplasia, eosinophils and plasmocyte infiltration were obvious. These results confirm that a mouse model of allergic rhinitis was successfully constructed in this study and the pathogenesis of allergic rhinitis was related to Th1/Th2 imbalance.

OBJCETIVETo investigate the method of separation of culture of bone microvascular endothelial cells (BMECs) of human femoral head in vitro.

METHODSFrom October 2013 to January 2014,15 femoral heads without pathologic change from patients resected during hip replacement were selected involving 2 males and 13 females with a mean age of 71.2 years old ranging from 38 to 92. Cancellous bone in femoral head was bited into broken bone grain and transfered into medium in aseptic contidion. Cells were isolated by the methods of enzymic digestion and density gradient centrifugation,purified by differiential attachment. The characteristics of cells was observed by inverted microscope. vWF and CD31 immunofluorescence analysis was applied for identification of cells.

RESULTSThe number of cells was positively correlated with patients' age after 24 hours in primary culture. The older patients had the less cells numbered. After 4 to 5 days' culture, primary cells appeared short spindle,polygon shaped and cobblestone-like morphology. After 7 to 10 days' culture, primary cells proliferated densely, became fusion, arranged in swirl, and contact inhibition appeared significantly. Immunofluorescence staining revealed the cells were 100% positive for vWF and CD31, and it showed that the cultured cells were BMECs.

CONCLUSIONIt was a simple, steady, effective method with good reproducibility, by which highly purified human BMECs can be obtained.

AIM: To observe the surgical effects of the taumatic lens subluxation and cataract after manual fragmentation and emulsification of nucleus and foldable intraocular lens implantation.
METHODS: A 3. 0mm tunnel limbus incision was operated through the predicted bulbar conjunctiva and sclera on 26 cases ( 26 eyes ) with taumatic lens subluxation ( suspensory ligament rupture range less than 120 ) and cataract (Ⅰ ~ Ⅲ) . And after the manual fragmentation and emulsification of nucleus, foldable intraocular lens was implantated. Intraocular lens loop was imbedded in the middle of the lens zonular ligament breakup to reset the pouch. The surgical complications and postoperative vision changes were observed.
RESULTS:Three month after operation, 22 eyes had a intraocular lens centric position taking up 85% of the whole. Four eyes had a slightly eccentric position ( 1 ~2mm), taking up 15% of the whole. 21 eyes had their visual acuity 0. 5~0. 8, taking up 81% of the whole. Five eyes of visual acuity was 0. 2~0. 8. Within 24h intraocular pressure of 12 eyes (46%) after operation were elevated, and returned to normal after 2~7d. There was no severe complication during operation and postoperation.
CONCLUSION: The manual fragmentation and emulsification of nucleus and foldable intraocular lens implantation of the traumatic lens subluxation and the cataract through the 3. 0mm corneal sclera limbus tunnel incision is a simple and effective surgery.

Objective： The aim of this study was to approach an efficient way in the treatment of pericardial effusion of lung cancer.

Results： The total effective rate was 93.8％ with 13 cases of complete response rate and 2 cases of partial response rate. The median survival time was 6.5 months. 2 cases died from the relapse of pericardial effusion or no effect. Eleven cases had gastrointestinal tract reaction, and 3 cases with repression of bone marrow. However all side effects were controlled by treatment. Conclusion： Safe-Dwel Tlus drain with injecting cisplatin and etoposide into pericardial cavity may be a better way to control malignant pericardial effusion of lung cancer.

ObjectiveTo assess the efficacy and safety of Xuebijing injection for the treatment of severe acute pancreatitis (SAP).Methods An extensive search of related literatures from the Cochrane Library, EMBASE, China Biology Medicine (CBM), CNKI, VIP and Wanfang data up to March 2014 was performed. Randomized controlled trials (RCTs) regarding Xuebijing injection for the treatment of SAP were collected regardless of languages. Jadad scale was taken for quality evaluation of the included studies by two researchers. The patients in control group were given conventional treatment, and those of the Xuebijing group were given Xuebijing injection on the top of conventional treatment. The Cochrane Collaboration RevMan 5.2 software was used for data analysis regarding the effect of Xuebijing injection on the mortality, incidence of complication, effective rate, the length of stay in hospital, and the safety of the drug in patients with SAP.Results A total of 15 published reports meeting the inclusion criteria were enrolled. The methodological quality of the trials was low. Meta analysis showed that the mortality in Xuebijing group was significantly lower [odds ratio (OR) = 0.37, 95% confidence interval (95%CI) =0.17 - 0.77,P = 0.008], and the incidence of complication was also significantly decreased (OR = 0.26, 95%CI =0.14 - 0.45,P< 0.000 01) as compared with those of control group. The effective rate in Xuebijing group was significantly higher than that of the control group [relative risk (RR) = 0.85, 95%CI = 0.80-0.91,P< 0.000 01]. The length of stay in hospital in Xuebijing group was significantly shorter than that of the control group [mean difference (MD) = -5.28, 95%CI = -6.69 to -3.86,P< 0.000 01]. Adverse reactions of Xuebijing injection were reported in 2 studies. The adverse reaction in one study was headache and nausea, which were relieved by adjusting the speed of intravenous infusion, and mild rash was reported in another case, and it disappeared after the withdrawal of Xuebijing. Conclusions The currently available evidence shows that Xuebijing injection may have some therapeutic effect on SAP. Because of the low methodological quality of the included trials, multi-center and high-quality RCTs with large sample sizes are needed to provide stronger evidence.
