OBJECTIVETo confirm the relations between the expression of cyclin E, p16ink4, ki67 and HPV16/18 infection using cervical exfoliated cells, and evaluate the usefulness of cyclin E, p16ink4 and ki67 as biomarkers for screening of cervical carcinomas.
METHODSThe expression of cyclin E, p16ink4 oncoproteins and ki67 proliferative activity was evaluated immunohistochemically in 78 cervical exfoliated epithelial specimens. Human papillomavirus type16 and 18 (HPV16/18) infection was assessed by polymerase chain reaction (PCR) using type specific primers.
RESULTSCyclin E, p16ink4 and ki67 were all overexpressed in cervical preneoplasia and neoplasia cells, compared with little expressed in ASCUS (P less than 0.005). Overexpression of cyclin E was observed in CIN, (P less than 0.01), p16ink4 and ki67 overexpressed in invasive carcinoma(100 percent and 90.9 percent respectively). The degree of p16ink4 and ki67 expression correlated well with the degree of cervical neoplasia (P less than 0.005). HPV16 infection was assessed at all stages of cervical neoplasia samples, and a significant relationship with the degree of cervical epithelial lession was observed at the same time. The expression level of p16ink4 and ki67 seemed to be more closely associated with HPV16 infection than cyclin E did (rs=1.0 vs rs=0.4). HPV18 was found positive in only 1 case in CIN1 and in 4 cases in CIN2-3. Therefore no significance was found on statistical analysis (P less than 0.005).
CONCLUSIONCyclin E, p16ink4 and ki67 should be regarded as useful biomarkers of HPV-related cervical neoplasias, and be used for screening patients at high risk for developing cervical carcinomas. Moreover, cyclin E might be a significant cytologic marker for the primary screening of cervical carcinomas.

OBJECTIVETFo compare the efficacy and complications rate of intramedullary (IM) nailing or K-wire versus plating fixation for clavicular fractures.
METHODSPubmed, Embase, Cochrane Library databases, CNKI, VIP and Wangfang databases were searched to find all randomized or quasi-randomized controlled trials of clavicle fractures using plating versus IM nailing or K-wire. The methodologic quality of the studies was assessed. After independent study selection by 2 authors ,data were collected and extracted independently. Outcomes of postoperative shoulder functional measurement, the efficacy and information of the operation and complications rate were meta-analyzed using RevMan 5 software.
RESULTSNine hundreds and seventy-six patients in 10 randomized controlled trials (RCTs) and 3 quasi-RCTs were involved in the meta-analysis,of which 5 studies compared the K-wire and the plating fixations and 8 studies compared the IM nailing and the plating fixations. The overall odds ratio(OR) (with 95% CI) of the operation efficacy for K-wire versus the plating was 3.79 (1.93, 7.46). The overall weighted mean difference (with 95% CI) of Constant Shoulder score for plating versus IM fixation was -1.39 (-3.43, 0.65) in 6 studies. The overall OR of the plating versus IM nailing was 9.34(2.70, 32.32) for the overall major complications in 5 studies and 5.04 (1.52,16.77) for the revision rate in 5 studies.
CONCLUSIONThe current limited evidences suggested that the IM fixation could reduce the incidences of the overall major complications and the revision surgery, while the post-operative efficacy of the plating was superior to the K-wire. More high quality RCTs are still needed in the future.

OBJECTIVETo investigate the differential diagnosis of type III prostatitis and interstitial cystitis so as to improve the efficiency of diagnosis and treatment of the two diseases.
METHODSBased on the clinical data of 4 cases of type III prostatitis and 3 cases of interstitial cystitis, we analyzed the characteristics of the two diseases in such aspects as clinical symptomatology, urodynamics, prostatic fluid microscopy, microbiology and treatment.
RESULTSThe common clinical characteristics of type III prostatitis and interstitial cystitis were indisposition or pain in the subabdomen and/or pelvic floor, but their differences were quite obvious. In interstitial cystitis, longer urine accumulation could cause worse pain in the subabdomen, which could be relieved after micturation, and the bladder capacity was obviously decreased, but with normal prostatic fluid and negative result of microbial culture. It responded to behavior therapy, resiniferatoxin, sodium hyaluronate and water dilation of the bladder under anaesthesia. While type III prostatitis, with white blood cells > 10/HP or < or = 10/HP in the prostatic fluid and negative result of microbial culture, did not respond to the above therapeutic methods that were effective for interstitial cystitis.
CONCLUSIONType III prostatitis and interstitial cystitis, although clinically confusable, can be definitely differentiated from each other according to their characteristic causes and locations.

OBJECTIVETo observe and compare the protective effect of garlic oil against carbon tetrachloride (CCL)-induced acute liver injury.
METHODSThe experiments include 4 preventive groups and 2 therapeutic groups. In every preventive and therapeutic group, the mice were randomized into 6 groups with 15 each, including one negative control group, one solvent control group, one CCl4 model group and 3 garlic oil groups (25, 50, and 100 mg/kg body weight). Before given a single gavage of CCl4 (80 mg/kg), the mice were pretreated with garlic oil by gavage in preventive group 1 (30 days, once daily), preventive group 2 (5 days, once daily), preventive group 3 (ahead of 2 h, once), preventive group 4 (immediately, once) or the vehicle (corn oil, 10 ml/kg) in solvent control group. In therapeutic groups, the mice were gavaged garlic oil 2 h (once, in therapeutic 1) or for 5 days (once daily, in therapeutic 2) after administration CCl. After 24 h of the last administration, blood was collected and centrifuged at 2500 r/min at 4 degrees C for 10 min, and serum was removed to measure ALT and AST activities. The liver was dissected, weighed to calculate the liver coefficient (relative liver weight). At the same time, the liver samples were studied by histological examinations.
RESULTSCompared with negative group, the liver coefficient and the activities of ALT and AST in serum of model group were increased remarkably (P < 0.01). Compared with CCl model group, the liver coefficient and the activities of ALT and AST in serum were decreased significantly (P < 0.01) by garlic oil dose-dependently in each preventive group. Simultaneously, histological assessment showed that garlic oil effectively alleviated hepatocyte injuries induced by CCl4. Comparing the preventive effects of garlic oil in every group, it was better in preventive group 3 than others. However, all indexes and histological examinations in therapeutic group 1 did not show the difference with those of CCl4 model group. In therapeutic group 2, all indexes recovered after 5 d of CCl4 administration.
CONCLUSIONSGarlic oil can prevent acute liver injury induced by CCl4 and the effect is better in ahead of 2 h group than others.

OBJECTIVETo investigate the effects of electromagnetic radiation on the physiological indices and immune function of operators.
METHODSThe general conditions and electromagnetic radiation awareness rate of 205 operators under electromagnetic radiation were evaluated using a self-designed questionnaire. Physical examination, electrocardiography, and routine urine test were performed in these operators. Peripheral blood was collected from the operators under electromagnetic radiation for blood cell counting and biochemical testing, and their peripheral blood lymphocytes were cultured for determination of chromosomal aberrant frequency and micronucleus frequency. The data from these operators (exposure group) were compared with those of 95 ordinary individuals (control group).
RESULTSThe chief complaint of giddiness, tiredness, dizziness, and amnesia showed significant differences between the exposure group and control group (P < 0.01), and the difference in headache became larger with an increase in working years. The awareness rate of electromagnetic radiation damage was significantly higher in the exposure group than in the control group. The difference in bradycardia was significant between the two groups (P <0.01), and the incidence was higher with longer working years. Significant differences between the two groups were also found in the numbers of individuals with elevated alanine aminotransferase, total bilirubin, and direct bilirubin (P < 0.01), populations with increased lymphocyte ratio and decreased neutrophil ratio (P < 0.01), populations with positive occult blood, urobilinogen, and bilirubin tests, and the number of individuals with increased micronucleus frequency of cultured peripheral blood lymphocytes (P < 0.01). In addition, the exposure group had significantly increased complement C3 and C4 (P < 0.01), significantly increased IgG (P < 0.05), and significantly decreased IgM (P < 0.01), as compared with the control group.
CONCLUSIONElectromagnetic radiation may lead to the changes in physiological indices, genetic effects, and immune function and affect the health and immune function in operators. The adverse effects are increased as the working years increase. So it is important to strengthen occupational protection of operators under electromagnetic radiation.

AIM: To observe thickness and morphological changes of bulbar conjunctiva pre- and post epidemic hemorrhagic conjunctivitis ( EHC ) therapy by optical coherence tomography ( OCT) .
METHODS: Observed morphological changes and measured the bulbar conjunctiva thicknesses of 29 cases (36 eyes) of incipient (1-2d) EHC patients, who were received and treated by department of ophthalmology, the Putuo Affiliated Hospital of Shanghai University of Traditional Chinese Medicine from May 2013 to December 2013, by OCT. Then measured the thickness again on 7, 14d after the therapy.
RESULTS: Among 29 patients (36 eyes), 7d after the EHC therapy, in 27 cured eyes, the full-thickness ( before 344. 00±59. 91μm, after 230. 19±22. 16μm, t=11. 75, P<0-01); epithelial thickness ( before 56. 52±6. 19μm, after 51. 37±5. 53μm, t=4. 61, P<0. 01); and stromal thickness (before 287. 11±60. 56μm, after 178. 81±20. 20μm, t=10. 69, P<0. 01) of patients' bulbar conjunctiva were thicker than values measured after therapy with significant difference. Significant difference was also found for full-thickness ( before 361. 39±65. 56μm, after 233. 44±22. 57μm, the difference was statistically significant, t=14. 45, P<0. 01);epithelial thickness ( before 55. 50±6. 72μm, after 46. 67±5-24μm, t=10. 06, P<0. 01) and stromal thickness ( before 305. 61±66. 02μm, after 186. 78±21. 82μm, t=13. 11, P<0-01 ) of patients' bulbar conjunctiva between values measured before and 14d after therapy.
CONCLUSION: The OCT is able to measure the thickness of bulbar conjunctiva in EHC patients. An significant increase was found in full, epithelial and stromal thickness of EHC patients' bulbar conjunctiva. With recovery from the disease, subepithelial fluid, interlaminar fluid and edema of the bulbar conjunctival stroma faded away firstly, which provide references for clinical therapies of the EHC.
