Objective: To investigate the relationship between human papilloma virus (HPV) gene types and cervical diseases. Methods:The subjects included women with HPV who were diagnosed in the Outpatient Department of the Third Affiliated Hospital of Sun Yat-sen University (Guangzhou, China) from March 1, 2010 to January 31, 2011. A total of 21 HPV DNA types were found in the women using DNA flow-though hybridization genotyping technique, and a questionnaire-type survey was conducted on these pa-tients. In this study, 256 cases of normal or inflamed cervix, 34 cases of cervical intraepithelial neoplasia I (CINⅠ), 61 cases of CINⅡor CINⅢ, and 9 cases of cervical cancer were analyzed. Results:The HPV infection rates were 18.4%in the normal cervical or inflam-mation group, 67.6%in the CINⅠgroup, 96.7%in the CINⅡor CINⅢgroup, and 100%in the cervical cancer group. The HPV in-fection rate was higher in the CIN I group than in the normal HPV infection or inflammation group (P<0.001) and was higher in the CIN Ⅱ or CIN Ⅲ groups than in the CIN I group (P<0.001). The main types of infection were HPV16 (44.2%), HPV58 (24.2%), HPV52 (11.6%), and HPV33 (8.4%) in the CIN groups. The main type of infection was HPV16 in the cervical cancer group (88.9%). Conclusion: Cases of cervical lesions are increasing. With this prevalence of HPV, considerable attention should be focused on HPV16-, 58-, 52-, and 33-related infections and cervical lesions. Among them, HPV16 infection is the primary cause of disease progres-sion and carcinogenesis.

Objective To determine whether peritoneal mesothelial cells express CD40 and to investigate potential mechanism by which CD40-CD40 ligand(CD40L) interaction may be involved in the inflammation of peritoneal membrane. Methods Rat peritoneal mesothelial cells (MC) were harvested from peritoneal cavity and maintained under defined in vitro conditions. Expression of CD40 on MC under normal culture or stimulation with interferon-?(IFN-?), tumor necrosis factor-?(TNF-?), interleukin(IL)-1 was examined by RT-PCR and FACS analysis. After activation with CD40 mAb, the expression of intercellular adhesion molecule-1 (ICAM-1) on MC was analyzed by FCAS. Results MC cultured in vitro expressed CD40 constitutively. The expression of CD40mRNA and CD40 protein up-regulated markedly following the stimulations with IFN-?, but not with IL-1, TNF-?. The expression of ICAM-1 on MC was significantly increased after activation of CD40 with IFN-? and CD40mAb. Conclusions MC functionally expresses CD40. The interaction of CD40 on MC and CD40L+ cells in peritoneal cavity may play an important role in peritoneal local defense and may be involved in the inflammation process of peritoneum.

Objective To study the kidney histological categories of isolated hematuria in children.Methods Twenty-three children with isolated hematuria were performed renal biopsy under real time ultrasound guidance utilizing menghini style negative pressure biopsy device after local anesthesia or general anesthesia.The renopuncture tissue was directly sent by the mail-boxes to the remote pathologic service.All of the biopsies were examined by light microscopy,electron microscopy and immunohistochemistry.Results Biopsies were classified as measangial proliferative glomerulonephritis(MsPGN)(8 cases),minimal change nephropathy(MCN)(5 cases),IgA nephropathy(IgAN)(4 cases),thin basement membrane nephropathy(TMN)(3 cases),Alport′s syndrome(AS)(1 case),focal segmental glomerulosclerosis(FSGS)(1 case)and IgM nephropathy(IgMN)(1 case).Conclusions In this series,MsPGN,MGA,IgAN are the most common biopsy diagnosis.TMN and Alport′s are account for some proportion.A few IgMN and FSGS may also present as isolated hematuria.

Objective To search for the changes of T cells subpopulations and immunoglobulin and their relation-ship in children patients with simple nephrotic syndrome. Design Case-control research. Patients aud Participants 39 patients with simple nephrotic syndrome were divided into two groups:the incipient group and relapse group (6 cases were determined at the incipient and relapse time) .Thereare 28 patients in incipient group, 19 males and 9 females, at the age of 2 to 10 years old. There are20 patients in relapse group, 12 males and 8 females, at the age of 3 to 13 years old. There are 35health children in control group, 21 males and 14 females, 2～13 years old. Interventions T cells subpopulations were determined by indirect immunofluorescence of OKT linesmonoclonal antibodies. The serum IgG was determined by routine simple agar immunodiffusion tests. Results and Conclusions The CD_3~+ and CD_4~+ cells are of no change in the children patients withsimple nephrotic syndrome, and the CD_8~+ and CD_(10)~+ cells are obviously increased, the Values of CD_4~+/CD_8~+ are obviously lower than those in the control qroup, there are no difference between the incipientand relapse groups. The levels of serum IgG were decreased in the 85.3% children patients, IgM were inc-reased in 29.4% of that. The values of CD_4~+/CD_8~+ have positive correlation and negative correlationwith the levels of serum IgG and IgM respectively.

Objective To study postoperative delirium in elderly patients.Methods We investigate the morbidity of postoperative delirium in 142 elderly patients (≥ 60 years)after gastrointestinal surgery by using Confusion Assessment Method (CAM) and Delirium Rating Scale Revised-98 (DRS-R98) scores.Data were analyzed using Student's t test and Chi-squaretest respectively with SPSS 19.0.Results Of 142 patients,delirium was diagnosed in 36 patients(25.4％),delirium developed in 4,7,17,7,1 patients in posto perative 1,2,3,4-7,7 + days respectively.There were significant difference in hospital stay:17.7 ± 2.6 days (postoperative delirium) and 13.4 ± 2.3 days (no postoperative delirium),t =4.608,P =0.000 1.The postoperative complications (52.8％ / 23.6％,x2 =10.710,P =0.001) and ICU admission (22.2％/6.6％,x2 =6.939,P =0.008) significantly increased.Conclusions Postoperative delirium is recognized as one of the most common surgical complications in elderly patients with gastrointestinal surgery leading to other major postoperative complications,and prolonged hospitalization.

200 papers on nerve root type cervical spondylosis treated with Chinese medicine were retrieved and 38 papers with complete diagnostic criteria and medical statistics were included for study. The results showed acupuncture, massage, and herbal therapy were three common methods and have their own advantage, but systemic, standardized and normative treatment program was lack. In the meantime of treating nerve root type cervical spondylosis, prevention should also be paid attention. The treatment, prevention and exercise on the whole therapeutic idea should be established, which has far-reaching significance.

Objective:This study aimed to establish a mouse model of breast cancer by inoculating human breast cancer cells into mice with normal immune function. Methods:Forty female BALB/C mice were randomized into four groups, with 10 mice in each group. The four groups were established according to the dosage of cyclophosphamide and prednisone, namely, the control group, low dose group, medium dose group, and high dose group. The mouse models of breast cancer were established by injecting human breast cancer cells into the fat pad of the right second breast of mice in the groups. Mice in the four groups were observed based on the time of tumorigenesis, rate of tumor formation, tumor imaging and pathological features, and metastasis of vital internal organs. Results:In the high dose group, the time of tumor formation was lower than that of the other groups, but the rate of tumor formation was high. Some visceral metastases occurred in the mice. By contrast, the medium dose group revealed completely opposite results. No death and tumor formation in both the control and low dose groups were reported. Conclusion:A human breast carcinoma model in mice was successfully established. Using this model, the onset and development of breast cancer could be much better imitated in the normal immune system of mice.

Objective To evaluate protein kinase Cθ(PKCθ)for the differential diagnosis of gastrointestinal stromal tumors(GIST).Methods The expression pattern of PKC θ was detected by immunohistochemistry in 121 GISTs,paired 51 distant normal tissues and 70 non-GIST sarcomas.Results Immunoreactivity for PKC θ was detected in 111 of 121 GIST cases,all eight CDll7-negative GISTs were PKC θ positive.PKC θ was negative in all distant normal tissue samples and 26 smooth muscle tumors.The positive expression rate of gastrointestinal mesenchemal tumors other than GIST was 18.2％.The expression rate of PKC θ did not vary with of tumor location,cell morphology and risk grades.Conclusions PKC θ could be a potential diagnotic marker in GIST patients,especially in those with negative CD117.

A total of 41 patients with aspiration pneumonia after nasopharyngeal carcinoma radiotherapy were retrospectively selected from January 2005 to December 2010.They were divided into early bronchoscopy group (n =24) and conventional therapy group (n =17) to analyze the therapeutic effects of early bronchoscopy on temperature,white blood cell (WBC),absorption of chest radiography and mortality rates.The temperature and WBC were at the same level between both groups at pre-treatment [(38.7 ±0.7)℃ vs.(38.5 ±0.7)℃,P=0.633; (15.8 ±4.2) × 109/L vs.(16.2 ±3.4) × 109/L,P =0.430]while the temperature declined obviously after a 3-day treatment [(37.3 ±0.9)℃ vs.(38.4 ± 1.4)℃,P =0.015] and also WBC after a 5-day treatment[(10.6±4.2) × 109/L vs.(15.3 ±6.9) × 109/L,P=0.045].The bronchoscopy group had a faster absorption of chest radiography (Z =-3.515,P =0.00).The mortality rate showed no statistically significant difference between both groups.
