OBJECTIVETo observe the therapeutic efficacy of Dangfei Liganning Tablet (DLT) in the treatment of antipsychotics induced mild hepatic damage.

METHODSTotally 80 mental inpatients with antipsychotics induced mild liver injury were randomly assigned to two groups, the treatment group (40 cases) and the control group (40 cases). Patients in the treatment group took DLT, two tablets each time, three times per day, while those in the control group took Liver-protecting Tablet (LT), four tablets each time, three times per day. The treatment course was 4 weeks for all. Changes of glutamic-pyruvic transaminase (ALT) and glutamic-oxalacetic transaminase (AST) were observed before treatment, week 1, 2, and 4 after treatment. The therapeutic efficacy was compared between the two groups.

RESULTSCompared with the former time point, ALT and AST gradually decreased in the two groups at week 1, 2, and 4 (P <0. 05). The cured rate was 72. 5% and the total effective rate was 97. 5% in the treatment group. They were 62. 5% and 90. 0% respectively in the control group. There was no statistical difference in the two indices between the two group (P >0.05). No obvious adverse reaction occurred in the two groups.

CONCLUSIONDLT could treat antipsychotics induced mild hepatic damage in a safe and effective way.

Objective To investigate the expressions and effects of interleukin-4(IL-4) and its alternative spliced variant(IL-4?2) in patients with atopic asthma.Methods The expressions of IL-4 and IL-4?2 were detected in 10 cases of patients with atopic asthma using a quantitative nested reverse-transcription polymerase chain reaction(RT-PCR) protocol.Result The expression level of IL-4 was higher in the patients with atopic asthma than that of the healthy controls.The median ratio of IL-4 to IL-4?2 was much higher in the patients with atopic asthma compared with that of the healthy controls.Conclusion The relative expression of IL-4 and IL-4?2 may play an important role in the mechanism of the pulmonary pathology in patients with atopic asthma,and may be one of the reason for the functional diversity of Th2 cells in different clinical conditions.

Objective:To evaluate the immune response efficiency of the recombinant abrin B chain protein (rATB) in BALB/c mice.Methods:BALB/c mice were vaccinated intraperitoneally (i.p.) with the purified rATB protein.ELISA was used to detect the IgG,IgG1 and IgG2a.Meanwhile,the expression of IL-4 and IFN-γwere detected by flow cytometry.Then the protein neutralization assay and efficacy of passive protection were done .Results:The anti-rATB antibody was detected by ELISA after vaccinated the rATB in the mice and results showed that the highest titer reached 106 ,which was acquired after the last vaccination .Meanwhile,a strong secondary response was triggered in mice when challenged with toxin .In contrast ,the antibody response of the PBS-vaccinated mice was less than 1:10 and P<0.05 indicated obvious difference between test group and control group .The result of IgG 1 was the same as the IgG ,while the result of IgG2a had not changed.There was significant difference for IL-4 between two groups (P<0.05),while no significant difference for IFN-γwas observed.All BALB/c mice survived after challenged with 5×LD50 of AT.Transfusion of sera from immunized mice provided passive protection in naive mice.Furthermore, the rATB could induce specific neutralizing antibodies against abrin toxin.Conclusion: The recombinant protein can induce the Th 2-type immune response and trigger a good immune response and protective efficacy,which means it may be a promising vaccine candidate against human exposure to AT .

OBJECTIVESTo study the correlation between positive rates of RNA in clinical confirmed severe acute respiratory syndrome (SARS) patients and its appearance in relation to the development of the disease in order to provide scientific basis for early diagnosis, effective prevention and treatment of the disease.

METHODSOne-step reverse transcription-polymerase chain reaction (RT-PCR) was used to amplify the SARS RNA in the clinical specimens from different courses of the disease. The representative amplicons were then sequenced. Chi-square for trend test was performed to study the correlation between positive rates of RT-PCR and at different periods after the onset of the disease.

RESULTSThe fragments amplified from the sputum specimens of SARS patients were shown to share 100% homology with the published SARS-associated coronavirus. Of the different clinical specimens, positive rate in the stools appeared to be the highest (21.55%). Chi-square for trend test revealed that the positive rates of stools and sputa of SARS patients decreased with the development of the disease (chi(2) for trend = 12.55 and 16.408, P = 0.0004 and P = 0.000 05 respectively).

CONCLUSIONOne-step RT-PCR proved to be an effective method for the detection of SARS-associated coronavirus from clinical specimens. Data as indicated that the positive rates of SARS coronavirus were decreasing in SARS patients along with the disease progression.

OBJECTIVETo study the factors in relation to severe acute respiratory syndromes (SARS) among health care workers and to develop related protective measures.

METHODSCase-control study was applied. A standardized questionnaire was used to collect SARS related information for health care workers who had contacted or treated SARS patients. Univariate analysis was conducted using SPSS 10.0 software package and multivariate logistic regression analysis was conducted using SAS 6.12.

RESULTSTwenty-seven of the 49 factors under study were significantly associated with SARS infection, in which 22 factors were protective, and the other 5 were risk factors. 27 factors were included for multivariate logistic regression analysis. Results showed that six factors as wearing eye glasses, wearing protection gowns, exposure to secrets/mode of contact with SARS patients, types of mask and the working years atc, remained significant association with hospital infection of SARS.

CONCLUSIONSARS infection in heath care workers was related to many factors during the process of diagnoses and/or treatment. It is recommended that adequate masks, eye-protection and protective gowns should be adopted for heath care workers during the process of clinical diagnoses and treatment of SARS patients.

OBJECTIVETo investigate the prevalence of obesity and distribution of body mass index (BMI) in school children of four ethnic groups in Urumqi, Xinjiang, China.

METHODSA total of 55508 school children of Han, Hui, Uygur and Kazak nationalities aged 8-18 years were selected by a cluster sampling from a districts of Urumqi City for anthropometric measurement and demographic survey. Prevalence of obesity and overweight and distribution of body mass index (BMI) by gender, age, and nationality were analyzed and compared. Cutoff points of BMI for defining obesity and overweight were based on the proposal set by the Working Group on Obesity in China (WGOC) to assess age-, gender- and nationality-specific prevalence of obesity and overweight.

RESULTSPrevalence of obesity was 5.34%, 6.78%, 3.39 %, and 1.22% for boys and 2.61%, 1.83%, 1.78%, and 1.40% for girls of Han, Hui, Uygur and Kazak nationalities, respectively. Prevalence of obesity tended to decrease with age overall, whereas that of overweight increased with age in Han children.

CONCLUSIONSPrevalence of obesity in school children in Urumqi varies with their nationalities and is lower than that of an average national level and a level of western countries. Obesity is more prevalent in boys than in girls of Urmuqi overall, which is just the opposite in Kazak children. Han boys and Hui girls have the highest prevalence of obesity and Kazak boys and girls have the lowest ones. Prevalence of obesity decreases with age, but that of overweight shows a different trend.

OBJECTIVETo explore the feasible age limits in Chinese elderly patients with non-Hodgkin's lymphoma (NHL).

METHODSThe clinical data of 507 patients with NHL who were admitted to Peking Union Medical College Hospital (PUMCH) from January 1990 to December 2007 were retrospectively analyzed. They were further followed up by reviewing medical records or by phone. The deadline of follow-up was October 2008.

RESULTSThe 5-year/8-year overall survival (OS) rates were 64.6%/45.7%, 53.0%/ 44.1%, 32.8%/17.5%, 40.0%/22.8%, and 19.8%/0, respectively, in patients aged < 60 years, 60-64 years, 65-69 years, 70-74 years, and > or = 75 years. The OS rate was significantly different between patients aged > or = 75 years and other age groups, and between patients aged 65-70 years and patients younger than 60 years (P < 0.05). Only age, serum albumin, and hemoglobin affected the survival status in elderly NHL patients.

CONCLUSIONSixty-five years can be regarded as the age limit in Chinese NHL patients.

OBJECTIVETo analyze the status of acute upper respiratory infection and influenza-like illness (ILI) among community residents in Jinan in 2015, and to make a understand of the patient's medical treatment behavior and influenza vaccination coverage status in 2014.

METHODSBalloting method and convenient sampling method were used to launch a household survey. The residents who had been in Jinan for more than 3 months were selected, to investigate the residents' attack ratio of acute upper respiratory and influenza-like from Jan. 8 to Feb. 7, 2015. Totally, 1 300 persons from 410 families were involved in this survey which recovered 1 241 valid questionnaires with the efficiency of 95.5%. Based on the national age-urban demographic statistics in 2010, the attack rates of acute respiratory infections, influenza-like illness were estimated by the direct standardization method, and the influenza vaccination rates were also calculated in this study. χ(2)-test method was used to compare the different status of incidence and vaccination among residents with different features.

RESULTSThe attack rate of acute upper respiratory infection and influenza-like illness in Jinan from January 8, 2015 to February 7, 2015 were 30.2% (375 cases), and 6.1% (76 cases), respectively, with a standardized rate of 29.1% and 5.4%. 5.3% (66 cases) of the residents have vaccinated with the influenza vaccine inoculation, with an adjusted rate of 3.8%. The attack rate difference of acute upper respiratory tract infections was statistically significant between each age group (χ(2)=17.121, P= 0.002). The 0-4 age group had a highest attack rate (45.4%) of acute respiratory infection, while the 15-24 age group got the lowest (26.5%). 38.9% (146 cases) of patients went for a treatment in hospital. Among them, 37.7% (55 cases) of them selected the county level hospitals for treatment, 37.7% (55 cases) selected the community level hospitals, and 24.6% (36 cases) selected the individual clinic. Significant differences of influenza-like illness attack rate between each age group were also found in this study (χ(2)=76.79, P<0.001). 0-4 age group had the highest attack rate (22.7%). 81.6% (62 cases) of the ILI sought treatment in the hospital, of which 53.2% (33 cases) selected county level hospital or above, and 33.9% (21 cases) selected community hospital, and 12.9% (8 cases) selected the individual clinic.

CONCLUSIONThe attack rate of acute upper respiratory infections among the residents of Jinan was high, whereas that of influenza-like illness was relatively low. 0-4 age group had a higher risk of ILI than other age groups. Most of the cases were likely to take the treatment in large hospitals. In general, the coverage rate of influenza vaccination was relatively low.

This study aimed to identify the type of carnitine palmitoyltransferase 2 (CPT2) gene mutation in the child with carnitine palmitoyltransferase II (CPT II) deficiency and her parents and to provide the genetic counseling and prenatal diagnosis for the family members. As the proband, a 3-month-old female baby was admitted to the hospital due to fever which had lasted for 8 hours. Tandem mass spectrometric analysis for blood showed an elevated plasma level of acylcarnitine, which suggested CPT II deficiency. The genomic DNA was extracted from peripheral blood of the patient and her parents. Five exon coding regions and some intron regions at the exon/intron boundaries of the CPT2 gene were analyzed by PCR and Sanger sequencing. Amniotic fluid was taken from the mother during the second trimester, and DNA was extracted to analyze the type of CPT2 gene mutation. Sanger sequencing results showed that two mutations were identified in the CPT2 gene of the proband: c.886C>T (p.R296X) and c.1148T>A (p.F383Y), which were inherited from the parents; the second child of the mother inherited the mutation of c.886C>T (p.R296X) and showed normal acylcarnitine spectrum and normal development after birth. It is concluded that the analysis of CPT2 gene mutations in the family suggested that the proband died of CPT II deficiency and that the identification of the mutations was helpful in prenatal diagnosis in the second pregnancy.
