Objective To explore the possible risk factors for autism spectrum disorders (ASD),and to pro-vide a basis for exploring the etiology of the disease.Methods This case -control study included 68 patients diag-nosed as ASD for a first lifetime(according to the fourth edition of the American Diagnostic and Statistical Manual of Mental Disordersfor ASD diagnosis)from May 201 4 to January 201 5,and 77 non -ASD controls (normal children, matched on gender)in Jiangxi Children′s Hospital were selected to undergo the risk factor survey for ASD.The survey content included 1 0 categories:general status,birth,feeding,the past history,mother′s pregnancy and her health condi-tion during pregnancy and environmental exposure,parents′occupational exposure,family history and relevant test re-sults.Logistic regression analysis was performed to analyze the results of the survey.Results The possible risk factors for ASD increased if mother had virus infection 2 years before pregnant (OR =7.97,95%CI:2.42 -26.31 ),had occu-pational exposure (OR =3.99,95%CI:1 .27 -1 2.52),volatile organic compounds exposure during pregnancy (OR =22.21 ,95%CI:2.28 -21 6.09),as well as living closely to transport passage ways during pregnancy (OR =0.59,95%CI:0.38 -0.93)or having a family heredity history (OR =58.50,95%CI:5.81 -589.57).Breastfeeding (OR =0.81 ,95%CI:0.66 -0.98)might be a protective factor in ASD.Conclusions In addition to genetic factors,the ute-rine environment from conception to birth and growth environment play an important role in the pathogenesis of ASD.

OBJECTIVE To investigate the incidence and pathogens of infection in 1659 consecutive cases in single center hematological unit.METHODS The incidence,pathogen,and outcome of infection in 1659 hospitalized patients with hematological disorders from 1999 to 2006 were retrospectively analyzed.RESULTS The overall incidence of infection was 24.4% according to the person-times of hospitalization,which included 22.1% of nosocomial infection and 2.3% of community acquired infection.Most of the pathogenic bacteria of the nosocomial infection were Gram-negative.The most common bacteria in the sputum samples included Enterobacter cloacae(19.3%) and Pseudomonas aeruginosa(14.8%).The most common bacteria in the blood samples were coagulase negative Staphylococcus(CNS,39.3%),the next was Pseudomonas aeruginosa and Escherichia coli.There were 4.21% bacteria resistant to most of antibiotics in nosocomial infection.There were 114 fungi isolated.Candida albicans was accounted for 35.1%.The mortality due to nosocomial infection was 7.4%.CONCLUSIONS The patients in hematology ward are susceptible to infection.The pathogens of nosocomial infection are most likely G-bacteria.Some bacteria are resistant to almost all antibiotics.The incidence of fungal infection is increasing in the near 8 years.

Objective To explore the diagnostic value of ultrasonography of fetal congenital cystic adenomatoid malformation of the lung (CCAM), and to predict the prognosis according to ultrasonographic findings. Methods The chest of 19 fetus with CCAM was multi-sectionally scanned with two-dimensional ultrasonography. The position, appearance and size of mass were observed, and complications were continuously followed. Results CCAM was pathologically confirmed in 13 fetus after induced abortion. One neonatal died, while CCAM in other 5 fetus disappeared before 36 weeks. The mass of typeⅠCCAM became smaller and smaller, and eventually disappeared. The echo-free spaces in typeⅡbecame smaller and fewer, and the strong echo weakened to the same level as normal lung. For type Ⅲ, the echo of solid mass weakened to the same level as normal lung, or transformed to typeⅡ gradually, and finally recovered to normal echo of lung as the gestational age increased. During follow up, there were 10 fetus (10/19, 52.63%) that lung adenoma cyst increased with the gestational age increased, and the heart, mediastinal shifted, pleural effusion, and (or) fetal edema were observed. Conclusion Ultrasound examination is a reliable method for the diagnosis of CCAM, and enable to predict the prognosis of the affected fetuses. If heart and mediustinum displacement, pleural effusion, hydrops fetal or other abnormalities exist, it's necessary to terminate the pregnancy.

It is held by some of the researches that the "16 collaterals" is composed of the "15 collaterals" and "the major collateral of stomach". And it is included into the textbook that Xuli, the major collateral of stomach, is the pulsation point at the cardiac region. Xuli is often explained as the empty portion of the human body by many researches. Through analysis and summarization of the related theory of the major collateral of stomach, the above mentioned opinion is discussed. And the understanding on the major collateral of stomach is deepened. As a result, it is concluded that count the major collateral of stomach into the 16 collaterals together with the 15 collaterals is inadvisable. The real pulsation point at the cardiac region locates under the left breast. And the real meaning of Xuli is "extending in all directions".

ABSTRACT:OBJECTIVE To investigate the role of connexin proteins (Cx), which form gap junctions (GJ), in progression and chemotherapeutic sensitivity of cervical cancer (CaCx). METHODS We analyze the expression of Cx26, Cx30, Cx32 and Cx43 in human specimens consisting of: Normal cervix (n=78), CaCx FIGO stage Ⅰ (n=148), CaCx FIGO stage Ⅱ (n=165). InCaCx cell lines, Hela- Cx32 (induced expression by doxycycline), C- 33A (endogenously express Cx32) and siHa (transiently transfected plasmid with Cx32), we detected the role of Cx32 against tostreptonigrin/cisplatin-induced apopotosisin presence or absence of functional GJ through using GJ inhibitors or low density cultural.Furtherly, we observed the relativity of Cx32 and EGFR expression in human specimens. Also, we detected the role of EGFR signaling pathway in the process of Cx32 anti-apoptosis through suppressed EGFR expression by inhibitors or siRNA sequences in cell lines. RESULTS We firstly demonstrated the expression of Cx32 was highly upregulated and accumulated in cytoplasm in the CaCx specimens, and the degree of upregulation correlated with advanced FIGO stages. Thus,in three human cervical cell lines, Cx32 was shown to suppress apoptosis when GJ formation is inhibited. No matter in cases of CaCx or cell lines, Cx32 expression was highly correlated with expression of EGFR and the EGFR pathway is an essential component of the Cx32-induced anti-apoptotic effect. CONCLUSION Cx32, traditionally tumor suppressive protein, was shown to be tumor protective against chemotherapy through EGFR pathway in a GJ-independent way.

Objectives To evaluate the efficacy of rituximab combined with chemotherapy in the treatment of diffuse large B-cell lymphoma (DLBCL) and the relationship of clinical prognosis with the International Prognostic Index (IPI) by the using rituximab in autologous peripheral stem cell transplantation (APBSCT) for the patients of DLBCL. Methods 21 patients with DLBCL, 11 patients of them were at IPI low risk, and 3 patients were IPI at low intermediate risk, 3 patients were at IPI high intermediate risk, 4patients IPI high risk. Rituximab combined with CHOP regimen (cyclophosphamide, adriamycin, vincfistine and prednisone) was given for 4～8 courses. 5 patients received APBSCT. The mobilizing regimen was rituximab combined with cyclophosphamide(CTX) and etoposide(VP16). The conditioning regimen were CBV(CTX combined with VP16 and carmustine). Results In 21 patients, the complete response rate was 61.9 %,with overall response rate 90.5 %. 2-year progression free survival was (69.74±10.43)%. 2-year overall survival was (84.44:1:8.35) %. The complete response rate was 92.9 % and overall response rate was 100 % in the patients IPI≤2. The overall response rate was 71.4 % in the patients with IPI≥3. The complete response rate was higher in the patients with IPI≤ 2 (P＜0.01). The amount of mononuclear cells (M NC) in harvest were 7.34 (4.6～8.53)×108/kg. The CD+34 cells in harvest were 8.82 (2.1～10.34)×1O6/kg. The mean time of neutrephil recovering to 0.5×109/L after APBSCT was +9 day. The mean time of platelet recovering to 20×109/L after APBSCT was +12 day. The major adverse reaction were infusion related response (14.3 %) and hematological toxieities. Conclusion The efficacy of rituximab combined with chemotherapy in the treatment of DLBCL is effective, The complete response rate was higher in the patients with IPI≤2 than in the patients with IPI≥3.Using rituximab in mobilizing regimen, all patients had harvested enough CD+34 cells. Rituximab given at +1day did not affect the hematopoiesis reconstruction.

Objective To observe the clinical efficacy of cupping in intervening non-alcoholic fatty liver disease (NAFLD), and further explore the possible mechanism. Method Fifty NAFLD patients were randomized into two groups: a treatment group (25 cases, intervened by cupping, Chinese medication, diet control and kinesiotherapy) and a control group (25 cases, intervened by Chinese medication, diet control and kinesiotherapy). They were observed for 6 months. Body weight, body mass index (BMI), abdomen circumference, hip circumference, arm circumference, thigh circumference, blood lipids [including total cholesterol (TC) and triglyceride (TG)], hepatic enzymes [including aspartate transaminase (AST) and alanine transaminase (ALT)], and B-scan ultrasound of liver were recorded before and after the treatment for statistical analysis. Result After 6-month treatment, the body weight, BMI, abdomen circumference, hip circumference, arm circumference, and thigh circumference were significantly improved in the two groups (P<0.05); some patients had their TC, TG, AST and ALT levels descended to the normal range and B-scan ultrasound of liver turned negative; the reduction of abdomen circumference in the treatment group was more significant than that in the control group (P<0.05). Conclusion Cupping plus Chinese medication, diet control and exercises can effectively improve clinical observation indexes of NAFLD, especially for those with central obesity.

OBJECTIVETo study the effects of methionine and choline on the expression levels of CaMKII and CREB mRNA and proteins in hippocampus of rats exposed to lead.

METHODSMale SD rats were divided into five groups. (1) control group, (2) group exposed to lead+2 by drinking water with 0.40 g/L lead acetate, (3) group exposed to methionine and choline (1:1, 400 mg/kg), (4) group exposed to 0.40 g/L lead acetate plus methionine and choline (1:1, 100 mg/kg), (5) group exposed to 0.40 g/L lead acetate plus methionine and choline (1:1, 400 mg/kg). In 8 weeks after exposure, all rats were killed. Then CREB mRNA and CaMK II mRNA expression levels in hippocampus were detected by real-time PCR, CREB and CaMK II protein expression levels in hippocampus were measured by western blot assay.

RESULTSThe expression levels (0.743 ± 0.185 and 0.729 ± 0.199) of CaMKII mRNA and CREB mRNA in the hippocampus of lead group were significantly lower than those (0.950 ± 0.238 and 0.901 ± 0.232) of control group (P < 0.05), also the expression levels (0.271 ± 0.045 and 0.212 ± 0.058) of CREB protein and pCREB protein in the hippocampus of lead group were significantly lower than those (0.319 ± 0.058 and 0.506 ± 0.125) of control group (P < 0.05). The expression levels (1.014 ± 0.210 and 1.126 ± 0.379) of CaMKII mRNA and the expression levels (1.029 ± 0.335 and 0.932 ± 0.251) of CREB mRNA in the hippocampus of 2 groups exposed to lead acetate plus methionine and choline were significantly higher than those of lead group (P < 0.05). The expression levels (0.407 ± 0.951 and 0.563 ± 0.178) of CREB protein and pCREB protein in the hippocampus of group exposed to lead acetate plus 400 mg/kg methionine and choline were significantly higher than those of lead group (P < 0.05).

CONCLUSIONMethionine and choline could decrease the inhibition effects of lead on the expression of CaMKII and CREB mRNA or CREB and pCREB proteins in the hippocampus of rats.
