Objective To explore the clinical characteristics of poststroke epilepsy and to discuss the association with the type of stroke,the location of focus.Methods Clinical information of 64 patients with poststroke epilepsy taken from 932 patients with stroke were analyzed retrospectively.Results In the patients with first stroke,the incidence of poststroke epilepsy was 6.9％.Among them,47 cases belong to early seizure (73.4％) and 17 cases belong to late seizure (26.6％).The incidence of poststroke epilepsy was difference between ischemic stroke and hemorrhagic stroke.There were more cases of stroke in cortical focus than subcortial one.Onset seizures type was more cases of partal seizure than generalized tonic-seizure (GTS).The treatment on early seizure could be short-range treatment and the treatment on late seizure should be long-term standardized treatment and regular.Conclusions Occurrence of poststroke epilepsy were involved in the type of stroke,the location of focus (cortex / subcortex).It is helpful for guiding the clinical therapy of patients with stroke and improving the quality of their life to analyse the clinical characteristics of poststroke epilepsy.

Objective To examine the efficacy and adverse reactions of bortezomib-based chemotherapy in treatment of multiple myeloma (MM).Methods Twenty-eight patients with multiple myeloma received a joint chemotherapy containing bortezomib.The efficacy was determined according to EBMT criteria.Results 28 patients received the chemotherapy,20 patients were newly diagnosed and 8 patients were relapsed or refractory.25 patients can be evaluateed efficacy.The total response rate was 100 ％ (25/25),consisting of 5 patients with complete response (CR),10 patients with almost complete remission (nCR),10 patients with partial remission (PR).The main side effects include peripheral neuropathy,thrombocytopenia,gastrointestinal disorders and viral infections.These side effects were improved by symptomatic treatment and generally did not affect the treatment.Conclusion For the newly diagnosed and relapsed or refractory multiple myeloma cases,bortezomib-based chemotherapy is a safe and effective therapeutic drug with rapid onset,high treatment response rate,and adverse reaction can be tolerated.

Health is one of the essential ties between China and Africa. As the Chinese economy is experien-cing rapid development and the strategic transformation, the China-Africa cooperation is entering the era of communi-tas in all directions and the health-related aids and exchanges between China and Africa are experiencing new oppor-tunities and challenges. Previously, the China-Africa health cooperation has experienced three transitional stages from the assistance, collaboration and communitas. During the current global fight against Ebola outbreak period, while the world feared and wondered the Ebola in the beginning, China’s fast action on the fight had showed that not only the relationship between China and Africa is seen from the previous health aid legacy to Africa, but also is coming to the economic development communitas stage. Moreover, there are two essential government and non-government col-laboration established between China and Africa. So, when we analyze the fast action of China towards Ebola out-break, it is clearly shown that the China’s response is based in the perspective of humanitarian, super state accounta-ble responsibilities, and also focused on health system resilience in the epidemic countries. China and Africa are stepping into the economic development communitas stage. Therefore, this change of cooperation reflects the change of China’s position in the global health governance.

Objective To evaluate the clinical efficacy of percutaneous transhepatic biliary drainage (PTBD) and pcrcutaneous transhcpatic insertion of biliary stent (PTIBS) for malignant biliary obstruction.Methods PTBD or PTIBS were performed in 56 patients with malignant biliary obstruction, which were aused by hepatic carcinoma (n = 14), biliary duct carcinoma (n = 11), gallbladder carcinoma (n = 5),stomach carcinoma accompanied with metastasis of lymph node (n = 14), carcinoma of ampulla (n = 1 ) or carcinoma of pancreatic head (n = 11 ). The diagnosis was confirmed by ultrasonography, CT or MRI in all patients. The obstructed site was well identified, including high obstruction in 19 patients and lower obstruction in 37 patients. Based on the imaging findings, suitable interventional procedure was employed.Results PTBD or PTIBS were performed successfully in all 56 patients, of them PTBD was adopted in 11,PTIBS in 40 and both PTBD and PTIBS in 5. The serum total bilirubin decreased from (295.65±152.86)μmol/L before the procedure to (151.05 ± 107.36) μmol/L after the procedure, (P < 0.01 ). Postoperative infection could affect the fading of jaundice (P < 0.01 ), but the location of the obstruction carried no relationship with the fading of jaundice (P = 0.063). Conclusion Both PTBD and PTIBS are safe and effective palliative therapies for malignant biliary obstruction, which can markedly relieve patient of jaundice,improve the quality of life and elongate the survival period.

Objective To develop a TaqMan MGB probe-based,sensitive and specific real-time fluorescence quantitative PCR assay for rapid detection of Helicobacter hepaticus.Methods Primers and probes specific toflaB gene of Helicobacter hepaticus were designed.A TaqMan MGB probe-based,real-time fluorescence quantitative PCR was established.The specificity,sensitivity and stability of the assay were assassed.Then,the established TaqMan MGB probe real-time fluorescence quantitative PCR assay was applied to detect Helicobacter hepaticus in 1081 clinical specimens during 2008-2011,compared with bacterial isolation and culture method and conventional PCR assay.Results The specificity of this established TaqMan MGB probe-based real-time fluorescence quantitative PCR was high and there were no cross-reactivity with Helicobacter pylori,Campylobacter jejuni,Clostridium piliforme,Pasteurella pneumotropica,Escherichia coli,Pseudomonas aeruginosa.The detection limits was 8.3 copies.The correlation coefficient and slope value of standard curve were 0.999 and -3.227,respectively and the efficiency of TaqMan MGB-based probe realtime fluorescence quantitative PCR assay was 100％.The TaqMan MGB-based probe real-time fluorescence quantitative PCR and conventional PCR were preformed to detect Helicobacter hepaticus in 1081 clinical specimens,a total of 86 specimens were positive for Helicobacter hepaticus.However,there was only 4 specimens were positive by bacteria isolation and culture method.The results showed that TaqMan MGB -based probe real-time fluorescence quantitative PCR for Helicobacter hepaticas was more sensitive than bacteria isolation and culture method,and it could detect Helicobacter hepaticus DNA from clinical specimens directly,and detection time is only 2 hours.Conclusion The TaqMan MGB-based probe real-time fluorescence quantitative PCR assay was a reliable,specific,sensitive and useful tool for rapid detection of Helicobacter hepaticus.

BACKGROUND:Airway epithelial regeneration can effectively inhibit submucosal hyperblastosis and the occurrence of obliteration. Studies demonstrated that ventilation could accelerate the regeneration of airway epithelium. OBJECTIVE:To establish and improve an orthotopic tracheal transplantation model and to further observe the effects of ventilation on trachea in alogeneic mice. METHODS:C57BL/6 mouse's tracheal served as donor, and BALB/c mouse's tracheal as recipient. This experiment contained two groups. In the experimental group, the membranous part of trachea was longitudinaly dissected in two donors and sutured into an enlarged trachea, which was implanted in the recipient. In the control group, donor's trachea was implanted into the recipient in situ. Samples were obtained and detected at 28 days after surgery. RESULTS AND CONCLUSION: Hematoxylin-eosin staining results demonstrated that compared with the control group, wel-differentiated ciliated epithelium was visible in the epithelial lamina of tracheal lumen, accompanying a few non-ciliated single or stratified squamous epithelium, mild submucosal fibrosis and inflammatory cel infiltration. Morphological analysis revealed that ciliated epithelial proportion in the experimental group was higher than in the control group (P < 0.05). The ratio of lamina propria to the tracheal cartilage, submucous fibrous tissuearea and the degree of lymphocyte infiltration were lower in the experimental group than in the control group (P < 0.05). Immunohistochemical staining demonstrated that the transplanted tracheal epithelium in both groups was recipient epithelial phenotype. Results verified that a modified orthotopic tracheal transplantation model was successfuly established. The increased ventilation of the tracheal alografts can accelerate the differentiation of tracheal epithelium. The wel-differentiated airway epithelium inhibited the proliferation of fibroblast.

Brucellosis is an infectious-allergic anthropozoonosis caused by invasion of Brucella.It belongs to category B infectious disease in China.The epidemic situation of brucellosis is raging again in China just like the rest of world.Especially after 2000,brucellosis became one of the fastest growing infectious diseases.By 2012,all Chinese administrative units at provincial levels except Taiwan had reported the cases of brucellosis.In this paper,we analyzed the epidemic features,prevention and control of brucellosis.We elucidated deep social reasons and the root problems,which impede the prevention and control of brucellosis.We have also discovered the important problems,which should be focused on and solved in the process of prevention and control of brucellosis.

Objective To investigate the clinical effects of lactobacillus acidophilus combined with glutathione in the treatment of nonalcoholic fatty liver disease.Methods 120 patients with nonalcoholic fatty liver disease were selected,and they were randomly divided into control group (60 patients used glutathione alone) and observation group (60 patients received lactobacillus acidophilus on the basis of control group).The clinical efficacy,liver function index,blood lipid index and the ultrasonography grading of fatty liver before and after treatment of the two groups were compared.Results The clinical total effective rates of the control group and the observation group were 76.67％,91.67％,respectively.The total effective rate of the observation group was significantly higher than that of the control group(x2 =10.52,P ＜ 0.05).The levels of AST,ALT and GGT of the observation group after treatment were significantly lower than those of the control group and before treatment [(36.89 ± 7.14) U/L,(36.89 ± 7.14) U/L,(36.89 ±7.14) U/L vs.(49.36 ± 11.08) U/L,(45.91 ± 10.24) U/L,(90.28 ± 20.70) U/L;(36.89 ± 7.14) U/L,(36.89 ± 7.14) U/L,(36.89 ± 7.14) U/L vs.(92.90 ± 24.3) U/L,(81.11 ± 17.37) U/L,(147.27 ± 34.19) U/L,t =2.88,2.54,2.91;3.01,3.36;3.18,3.48;3.41,3.87;all P ＜0.05).The levels of TG,TC,HDL-C and LDL-C of the observation group after treatment were significantly better than those of the control group and before treatment [(1.66 ± 0.42) mmol/L,(4.05 ± 0.77) mmol/L,(1.69 ± 0.60) mmol/L,(2.44 ± 0.38) mmol/L vs.(2.13 ± 0.80) mmol/L,(4.64 ± 0.94) mmol/L,(1.45 ± 0.48) mmol/L,(2.97 ± 0.57) mmol/L;(1.66 ± 0.42) mmol/L,(4.05 ± 0.77) mmol/L,(1.69 ± 0.60) mmol/L,(2.44 ± 0.38) mmol/L vs.(2.71 ± 1.33) mmol/L,(5.42 ± 1.27) mmol/L,(1.08 ± 0.36) mmol/L,(3.49 ± 0.71) mmoL/L,t =2.43.2.13,2.55,2.07;3.02,3.41;3.11,3.65;2.81,3.30;2.87,3.15;all P ＜ 0.05).In the control group,normal in 6 cases,mild in 24 cases,moderate in 21 cases and severe in 9 cases as fatty liver degree;in the observation group,normal in 13 cases,mild in 30 cases,moderate in 13 cases and severe in 4 cases as fatty liver degree.The ultrasonography grading of fatty liver of the observation group after treatment were significantly better than those of control group and before treatment (U =3.74,5.20,all P ＜ 0.05).Conclusion Lactobacillus acidophilus combined with glutathione in the treatment of nonalcoholic fatty liver disease can efficiently promote the recovery process of liver function,regulate blood lipid levels and is helpful to improve the imaging grading.

AlM: To evaluate the application of phacoemulsification of different nucleus density using ozil and traditional mode.METHODS: A total of 89 eyes (72 patients ) ( visual acuity was of 0. 6 and above after 1mo follow - up) of different nucleus density level (LOCS Ⅱ criteria grade Ⅲ 46 eyes, grade Ⅳ and more 43 eyes ) were randomly assigned into 2 groups: ozil group (group A), grade Ⅲ 22 eyes (torsional energy 80% lP on);grade Ⅳ and more 17 eyes (torsional energy 100% lP on); Traditional mode group(group B), grade Ⅲ 24 eyes (energy 50% ), grade Ⅳ and more 26 eyes (energy 60% ~ 70% ) . All surgeries were performed by the same experienced surgeon,who use the chop to split the nucleus in the application of phacoemulsification. lntraoperative parameters were total equivalent pawer ( TEP ), cumulative dissipated energy ( CDE ) and effective phaco time ( EPT ) and surgical complications. The effectiveness of the two modes in dealing with hard - core cataract phacoemulsification were compared.RESULTS: GradeⅢ nucleus dealing: TEP of ozil group was significantly higher than that of the traditional mode group [(24.58±7.78)% vs (13.84±1.97) %]and EPT of ozil group was significantly lower than that of the traditional mode group (50. 59±14. 73 s vs 60. 19±9. 04 s, P<0. 05). CDE showed no difference between two groups [(13.12±6.03)% vs (13.38±2.85)]. Grade Ⅳ and more nucleus dealing: CDE [( 34. 10 ± 13. 48 )%] and EPT (104. 64±32. 4s) of the ozil group was higher than CDE [(30. 31 ± 13. 48)%] and EPT (93. 01 ± 41. 01s) of the traditional mode group, but there were no difference between two groups. Obstacles in the needle of phacoemulsification surgery: ozil group 4/17, traditional mode group 2/26 (χ2=2. 16, P=0. 14).CONCLUSlON: Bothozil and traditional mode can deal with all kinds of nucleus effectively and safely. Ozil mode is more efficacy and quick deal in gradeⅢnucleus. With the increase of nucleus hardness, the traditional mode still have the advantage of high efficiency and no obstacle to dealing patients with grade Ⅳ and more nucleus. Choose according to different nuclear hardness ultrasonic model can improve the operation efficiency and security.
