Objective To identify the cellular distribution of a my elin-associated protein (Nogo-A) in the central nervous system (CNS) of mice a nd explore its possible inhibition on the CNS axon regeneration after spinal cor d injury. Methods Brain, spinal cord, peripheral tissues and w eight-dropping injuried spinal cord from the adult C57BL/6 mice were studied. N ogo-A protein expression was localized immunohistochemically. Chick E12DRG neur ons were cultured and growth cone collapse assessed. Results N ogo-A protein expression detected was mainly in the oligodendrocyte cell body a nd the myelinated axons surrounded by cell processes rather than in the peripher al tissues. After spinal cord injury, Nogo-A was up-regulated at a moderate de gree in the area around the lesion. Chick E12 DRG growth cone collapse rate was as high as 70%, significantly higher than that in the blank control and vector control groups with a significant difference ( P

Totally,42 319 malaria cases and 57 787 suspected cases with 48 deaths were reported by the Annual Case Repor-ting System in 1186 counties of 21 Provinces/Municipality/Autonomous Region(P/M/A) in 2005,and the annual incidence was 0.59/10 000,an increase of 55.3% than that of the last year.Through the Case Reporting Information System,an internet reporting process started in 2004,40 371 malaria cases were reported from 1 075 counties of 31 P/M/A.The number of malaria cases and the rank of P/M/A were basically in concordance by the two systems.Among the 1186 counties with reported malaria cases,27 counties had an incidence of more than 10/10 000 distributed in Yunnan(15 counties),Hainan(7 counties) and Anhui(5 counties).There were 80 counties in which the malaria incidence was between 1/10 000 and 10/10 000.The number of Plasmodium falciparum malaria cases was 4 146,accounting for 9.8% of the total cases,of which 63.5%(2 632) were imported cases in 178 counties/cities of 18 P/M/A.Indigenous falciparum malaria was found in 47 counties/cities of Yunnan and Hainan Provinces,of which 31 counties/cities were in Yunnan,increased by 29,16 counties/cities were in Hainan,same with that of 2004.Yunnan and Hainan Provinces are still relatively high transmission areas.Yunnan ranked No.2 in the country in terms of the number of cases while Hainan ranked No.1 by malaria incidence in 2005.19 588 malaria cases were reported from the two provinces in 2005,accounting for 46.3% of the total reported cases in the country.There were 15 072 cases with 38 deaths reported from Yunnan,the incidence was 4.95/10 000,an increase of 60.2% than that in the last year.Among the reported cases,3 497 were falciparum malaria with 69.0% imported from the bordering nations.The number of reported cases in Hainan was 4 516,with an incidence of 5.46/10 000,53.1% decrease than the last year.In central China,the resurgence of malaria was considerable in provinces along the Huai River,especially in Anhui Province.The number of malaria cases in Anhui came to the highest in the country in 2005,with 15 681 malaria cases and 7 662 suspected cases reported,accounting for 37.5% of the total cases in the country,and an incidence of 2.45/10 000,increased by 77.5% than that in 2004.The number of reported cases in Henan Province was 2 349,increased by 55.2% in incidence.Hubei Province reported 1 564 malaria cases with an incidence of 0.27/10 000,decreased by 42.6%.651 cases were reported from Jiangsu Province,almost the same as that in 2004.Focal outbreaks occurred in 277 villages of 20 counties in Anhui,Hubei and Jiangsu,where Anopheles sinensis is the principal transmission vector.Malaria cases reported from the above 4 provinces accounted for 47.8% of the national figure,increased approximately by 10% than the last year.Cases reported from P/M/A in the South and East China occupied about 4.9% of the total,similar to that in 2004.Several hundreds were reported from each of Guizhou,Sichuan,Guangxi,Guangdong,Zhejiang,Shanghai and Hunan.Less than 100 cases were reported from each of Fujian,Chongqing,Shandong,Shanghai,Jiangxi,Liaoning,Shaanxi,Shanxi and Gansu Provinces in 2005.High attention should be paid to Guizhou and Tibet.Focal outbreaks occurred in Guizhou for consecutive 4 years,and malaria cases in 2005 double increased than the last year.77.8% of the reported cases were indigenous patients,which implied that local transmission resulting from imported malaria cases has become a major problem in Guizhou.93 malaria cases were reported from Linzhi District of the Tibetan Autonomous Region in 2005,76 cases more than that in 2004.In summary,malaria is still an important problem of public health in China,especially in the southern and central parts.Yunnan and Hainan still faced a severe situation of malaria endemics with the spread of Plasmodium falciparum,especially imported malaria in the 25 border counties in Yunnan.In the central part of the country,especially Anhui Province,the malaria prevalence was highly unstable with frequent focal outbreaks in areas along the Huai River,which revealed new challenges to the malaria control program in China.In addition,more attention needs to be paid to the malaria control in Guizhou and Tibet.

Objective Sylvian Veins morphology analysis contributes to cortex veins protection for clear surgical fields, a better choice for operation plan evaluation. Methods 33 cases diagnosed as epilepsy, male∶female=19∶14, mean ages 18.7y (9-52). Results 4 types of Sylvian Veins spreading were observed from the procession of functional surgery: long stem pattern 49%(16/33), short stem pattern 15%(5/33), long truncks pattern 33%(11/33), and absent stem pattern 3%(1/33). Conclusion Sylvian Veins morphology analysis shows that there exist 4 main patterns, which may contribute to functional surgery about frontal operculum, temporal operculum and insular lobe or intracranial electrode placement.

Objective To explore the expression of HCCR, pERK and pELK1 in gastric cancer tissue and para-carci-noma tissue, and to explove its correlations. Methods In 60 human gastric cancers and their corresponding paraneo-plastic tissuses,the expression of HCCR, pERK and pELK1 were detected by immunohistochemistry. Results The ex-pression of HCCR was 75.0%(45/60), pERK, and pELK1 were 73.3%(44/60) and 71.7%(43/60), respectively, and the expression of proteins in gastric tumor were higher than that in paraneoplastic tissues (P<0.05). Conclusion The HCCR, pERK and pELK1 are higher expressed in tumor tissues, availably as a auxiliary index for clinical immunohis-tochemistry in gastric cancer.

Objective To study the outcomes of Lennox-Gastaut syndrome (LGS) with single-stage total corpus callosotomy combined with different resective surgeries. Methods Nine LGS patients, admitted to our hospital from May 2010 to May 2014, were chosen in our study. Their clinical data were retrospectively analyzed. According to the results of anatomy, electrophysiology and clinical comprehensive evaluation, all the 9 children received single-stage total corpus callosotomy combined with different resective operations. The differences of epileptic seizures of these children before and after surgery were compared. Results The 9 LGS children were followed up for 2 years;5 achieved Engel grade I, 3 achieved Engel grade II, and one achieved Engel grade III. The surgical effective rate was 88.9％ (8/9). The frequencies of drop seizures, convulsive seizures, tonic seizures and tonic-clonic seizures were decreased of different degrees, with drop seizures enjoying the best control. Three patients had transient silence, remarkable relief one week after surgery and total recovery half year after surgery. Conclusion Early single-stage total corpus callosotomy combined with different resective operations can help to control seizures in children with intractable LGS.

Objective:To investigate the epidemiological characteristics, diagnosis, treat-ment and prognosis of gallbladder cancer in China from 2010 to 2017.Methods:The single disease retrospective registration cohort study was conducted. Based on the concept of the real world study, the clinicopathological data, from multicenter retrospective clinical data database of gallbladder cancer of Chinese Research Group of Gallbladder Cancer (CRGGC), of 6 159 patients with gallbladder cancer who were admitted to 42 hospitals from January 2010 to December 2017 were collected. Observation indicators: (1) case resources; (2) age and sex distribution; (3) diagnosis; (4) surgical treatment and prognosis; (5) multimodality therapy and prognosis. The follow-up data of the 42 hospitals were collected and analyzed by the CRGGC. The main outcome indicator was the overall survival time from date of operation for surgical patients or date of diagnosis for non-surgical patients to the end of outcome event or the last follow-up. Measurement data with normal distribu-tion were represented as Mean±SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(range), and com-parison between groups was conducted using the U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Univariate analysis was performed using the Logistic forced regression model, and variables with P<0.1 in the univariate analysis were included for multivariate analysis. Multivariate analysis was performed using the Logistic stepwise regression model. The life table method was used to calculate survival rates and the Kaplan-Meier method was used to draw survival curves. Log-rank test was used for survival analysis. Results:(1) Case resources: of the 42 hospitals, there were 35 class A of tertiary hospitals and 7 class B of tertiary hospitals, 16 hospitals with high admission of gallbladder cancer and 26 hospitals with low admission of gallbladder cancer, respectively. Geographical distribution of the 42 hospitals: there were 9 hospitals in central China, 5 hospitals in northeast China, 22 hospitals in eastern China and 6 hospitals in western China. Geographical distribution of the 6 159 patients: there were 2 154 cases(34.973%) from central China, 705 cases(11.447%) from northeast China, 1 969 cases(31.969%) from eastern China and 1 331 cases(21.611%) from western China. The total average number of cases undergoing diagnosis and treatment in hospitals of the 6 159 patients was 18.3±4.5 per year, in which the average number of cases undergoing diagnosis and treatment in hospitals of 4 974 patients(80.760%) from hospitals with high admission of gallbladder cancer was 38.8±8.9 per year and the average number of cases undergoing diagnosis and treatment in hospitals of 1 185 patients(19.240%) from hospitals with low admission of gallbladder cancer was 5.7±1.9 per year. (2) Age and sex distribution: the age of 6 159 patients diagnosed as gallbladder cancer was 64(56,71) years, in which the age of 2 247 male patients(36.483%) diagnosed as gallbladder cancer was 64(58,71)years and the age of 3 912 female patients(63.517%) diagnosed as gallbladder cancer was 63(55,71)years. The sex ratio of female to male was 1.74:1. Of 6 159 patients, 3 886 cases(63.095%) were diagnosed as gallbladder cancer at 56 to 75 years old. There was a significant difference on age at diagnosis between male and female patients ( Z=-3.99, P<0.001). (3) Diagnosis: of 6 159 patients, 2 503 cases(40.640%) were initially diagnosed as gallbladder cancer and 3 656 cases(59.360%) were initially diagnosed as non-gallbladder cancer. There were 2 110 patients(34.259%) not undergoing surgical treatment, of which 200 cases(9.479%) were initially diagnosed as gallbladder cancer and 1 910 cases(90.521%) were initially diagnosed as non-gallbladder cancer. There were 4 049 patients(65.741%) undergoing surgical treatment, of which 2 303 cases(56.878%) were initially diagnosed as gallbladder cancer and 1 746 cases(43.122%) were initial diagnosed as non-gallbladder cancer. Of the 1 746 patients who were initially diagnosed as non-gallbladder cancer, there were 774 cases(19.116%) diagnosed as gallbladder cancer during operation and 972 cases(24.006%) diagnosed as gallbladder cancer after operation. Of 6 159 patients, there were 2 521 cases(40.932%), 2 335 cases(37.912%) and 1 114 cases(18.087%) undergoing ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) examination before initial diagnosis, respec-tively, and there were 3 259 cases(52.914%), 3 172 cases(51.502%) and 4 016 cases(65.205%) undergoing serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis, respectively. One patient may underwent multiple examinations. Results of univariate analysis showed that geographical distribution of hospitals (eastern China or western China), age ≥72 years, gallbladder cancer annual admission of hospitals, whether undergoing ultrasound, CT, MRI, serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis were related factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.45, 1.98, 0.69, 0.68, 2.43, 0.41, 1.63, 0.41, 0.39, 0.42, 95% confidence interval as 1.21-1.74, 1.64-2.40, 0.59-0.80, 0.60-0.78, 2.19-2.70, 0.37-0.45, 1.43-1.86, 0.37-0.45, 0.35-0.43, 0.38-0.47, P<0.05). Results of multivariate analysis showed that geographical distribution of hospitals (eastern China or western China), sex, age ≥72 years, gallbladder cancer annual admission of hospitals and cases undergoing ultrasound, CT, serum CA19-9 examination before initially diagnosis were indepen-dent influencing factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.36, 1.42, 0.89, 0.67, 1.85, 1.56, 1.57, 0.39, 95% confidence interval as 1.13-1.64, 1.16-1.73, 0.79-0.99, 0.57-0.78, 1.60-2.14, 1.38-1.77, 1.38-1.79, 0.35-0.43, P<0.05). (4) Surgical treatment and prognosis. Of the 4 049 patients undergoing surgical treatment, there were 2 447 cases(60.435%) with complete pathological staging data and follow-up data. Cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb were 85(3.474%), 201(8.214%), 71(2.902%), 890(36.371%), 382(15.611%), 33(1.348%) and 785(32.080%), respectively. The median follow-up time and median postoperative overall survival time of the 2 447 cases were 55.75 months (95% confidence interval as 52.78-58.35) and 23.46 months (95% confidence interval as 21.23-25.71), respectively. There was a significant difference in the overall survival between cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb ( χ2=512.47, P<0.001). Of the 4 049 patients undergoing surgical treatment, there were 2 988 cases(73.796%) with resectable tumor, 177 cases(4.371%) with unresectable tumor and 884 cases(21.833%) with tumor unassessable for resectabi-lity. Of the 2 988 cases with resectable tumor, there were 2 036 cases(68.139%) undergoing radical resection, 504 cases(16.867%) undergoing non-radical resection and 448 cases(14.994%) with operation unassessable for curative effect. Of the 2 447 cases with complete pathological staging data and follow-up data who underwent surgical treatment, there were 53 cases(2.166%) with unresectable tumor, 300 cases(12.260%) with resectable tumor and receiving non-radical resection, 1 441 cases(58.888%) with resectable tumor and receiving radical resection, 653 cases(26.686%) with resectable tumor and receiving operation unassessable for curative effect. There were 733 cases not undergoing surgical treatment with complete pathological staging data and follow-up data. There was a significant difference in the overall survival between cases not undergoing surgical treatment, cases undergoing surgical treatment for unresectable tumor, cases undergoing non-radical resection for resectable tumor and cases undergoing radical resection for resectable tumor ( χ2=121.04, P<0.001). (5) Multimodality therapy and prognosis: of 6 159 patients, there were 541 cases(8.784%) under-going postoperative adjuvant chemotherapy and advanced chemotherapy, 76 cases(1.234%) under-going radiotherapy. There were 1 170 advanced gallbladder cancer (pathological staging ≥stage Ⅲa) patients undergoing radical resection, including 126 cases(10.769%) with post-operative adjuvant chemotherapy and 1 044 cases(89.231%) without postoperative adjuvant chemo-therapy. There was no significant difference in the overall survival between cases with post-operative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.23, P=0.629). There were 658 patients with pathological staging as stage Ⅲa who underwent radical resection, including 66 cases(10.030%) with postoperative adjuvant chemotherapy and 592 cases(89.970%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.05, P=0.817). There were 512 patients with pathological staging ≥stage Ⅲb who underwent radical resection, including 60 cases(11.719%) with postoperative adjuvant chemotherapy and 452 cases(88.281%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemo-therapy and cases without post-operative adjuvant chemo-therapy ( χ2=1.50, P=0.220). Conclusions:There are more women than men with gallbladder cancer in China and more than half of patients are diagnosed at the age of 56 to 75 years. Cases undergoing ultrasound, CT, serum CA19-9 examination before initial diagnosis are independent influencing factors influencing initial diagnosis of gallbladder cancer patients. Preoperative resectability evaluation can improve the therapy strategy and patient prognosis. Adjuvant chemotherapy for gallbladder cancer is not standardized and in low proportion in China.
