Objective: To understand the use of condom among middle school students after outpatient abortion operation, so as to provide a basis for safe sex education and intervention. Methods: The questionnaire survey on condom use was conducted among the middle school students who had abortion operation in obstetric and gynecologic out patient clinic of Yuyao People s Hospital from 2016 to 2020. Group differences were compared by using Chi square test. Results: A total of 274 middle school students were investigated. The awareness rates on "AIDS can be transmitted through sexual contact" and "correct use of condoms can reduce the risk of AIDS through sexual transmission" were 93.80% and 91.24% respectively. The rate of condom s usage was 17.88% in the past 6 months, 5.47% of participants used condoms every time, 12.41% used condoms occasionally, and 82.12% never used condoms. About 18.37% of participants who used condoms every time or occasionally could use correctly. The top three reasons were "I don t think it s so coincidental to get pregnant once in a while" (16.44%), "I think it s very troublesome to use it" (14.67%), "I didn t expect to use it, let alone prevent diseases" (14.22%). Conclusion Yuyao City flow of students related AIDS knowledge awareness rate is high, and the condom utilization rate, the correct utilization rate is very low. According to the main reasons of not wearing condoms, do a good job of the correct use of condom publicity, through targeted sex education and intervention, to achieve the purpose of from "knowledge" to "faith" and ultimately to "practice".

Objective To study the clinical therapeutic effect of the combined antihistamine for the treatment of allergic pharyngitis.Methods In January 2015 to December 2016 during the hospital outpatient service received by irritating cough,50 patients with pharyngeal itching for the main symptoms as the object of study,summary and analysis on the clinical symptoms of all patients,in the conventional treatment on the basis of leukotriene receptor antagonist combined antihistamines treatment,close observation after 1 week,2 weeks after treatment in patients with symptoms improved after treatment.Results The clinical main characteristic of allergic pharyngitis is the irritating dry cough,and the first pharynx is a cough.After a week of treatment,the symptoms of the patient were significantly improved,and after two weeks of treatment,the symptoms of the patient continued to be improved and the results were significant.Conclusion In clinical patients with cough,is one of the most important causes of allergic pharyngitis,if the patient is not adopted in treatment of anti-allergic drugs,can lead to therapeutic effect,but the joint antihistamines leukotriene receptor antagonist treatment,can effectively eliminate the symptoms of allergic pharyngitis,obvious effect,effectively improve the patient's quality of life.

Objective To investigate the changes and clinical significance of neck-shaft angle in the treatment of proximal humerus fractures with locking plate.Methods A retrospective case-control study was done on 214 cases of proximal humerus fractures treated with locking plate in our hospital from January 2008 to June 2016.According to the presence of medial bone defects,the cases were divided into medial bone defect group (85 cases) and non-medial bone defect group (129 cases).In medial bone defect group,there were 35 males and 50 females,with an average age of 63.3 years old.In this group,the cases of Neer three-part fractures and Neer four-part fractures were 47 and 38,respectively.In non-medial bone defect group,there were 51 males and 78 females,with an average age of 65.9 years old.In this group,the cases of Neer three-part fractures and Neer four-part fractures were 57 and 72,respectively.The preoperative humeral neck-shaft angle of contralateral humerus,and the humeral neck-shaft angle with its changes on the second postoperative day as well as 1,3,6 and 12 months after surgery were evaluated by the X-ray film.The Constant scores of the shoulder function were also assessed.Results The follow-up time for the patients ranged from 12 to 42 months (mean 24.2 months).In medial bone defect group,the preoperative neck-shaft angle of contralateral humerus,as well as neck-shaft angles of fractured side at five follow-up visits were (133.4±4.0) °,(134.7 ±11.5) °,(120.8±4.0) °,(118.5 ±3.5) °,(117.9 ±10.4) °and (114.7 ±4.4)°,respectively.While in the other group,the corresponding parameters were (134.0±2.4)°,(133.8± 17.1)°,(135.6± 2.9)°,(132.7± 2.8) °,(131.5 ± 13.5) °,(135.2 ± 2.8) °,respectively.There were significant differences between the two groups of the neck-shaft angle at 1,3,6 and 12 months (P ＜ 0.05).In the medial bone defect group,there were no significant differences between neck-shaft angle of contralateral humerus and the second postoperative day (P ＞0.05),but both of them are significantly greater than others(P ＜0.05).In the other group,except for the neck-shaft angles of postoperative 1 month and 6 months (P ＜ 0.05),there was no statistically significant difference between the angles in different time points(P ＞ 0.05).The mean Constant scores of medial bone defect group and no medial bone defect group were (69.3 ± 14.6) and (75.2 ± 12.6),respectively.Conclusions After the recovery of neck shaft angle,there is still a need of attention to the losses of neck shaft angle after surgery.Neck-shaft angle could be a reference for the treatment strategy of proximal humerus fractures with locking plate,which could guide the anatomical reduction as well as be used to evaluate the effects after surgery.It could also be a reference for function exercise.Moreover,the losses of neck shaft angle will be influenced by supporting from internal side,which could have effects on the function recovery after surgery.

OBJECTIVE:To provide reference for rational drug use in the clinic. METHODS:Irrational medication orders eval-uated by the Affiliated Cancer Hospital of Zhengzhou University during Oct. 2014 to Sep. 2015 were arrangemented,summarized and analyzed. RESULTS:A total of 515 inpatient medical records were reviewed and analyzed,among which there were 165 unrea-sonable medical records and 185 irrational medication orders. Irrational medical records of general surgery department were the most(38 items,accounting for 23.03%). Irrational drug use mainly included irrational usage and dosage(80.00%),drug use with-out indications or not suit indications (7.57%),inappropriate solvent selection (4.86%). Including 66.22% of single overdose, 18.92% of longer medication duration. CONCLUSIONS:There are many irrational medical orders which should be standardized in our hospital,especially overdose and longer medication duration,which increase financial burden of patient. Pharmacists should strengthen communication with clinicians,and hold rational drug use trainings regularly base on the types of the irrationality. These can help to improve rational drug use and guarantee the safety of drug use.

OBJECTIVETo investigate the mechanism underlying the inhibitory effect of STOML-2 overexpression on apoptosis of human cervical squamous carcinoma Siha cells.

METHODSSiha cells were transfected with an adenoviral vector carrying STOML-2, and 72 h later STOML-2 expression and the proliferation of the cells were detected by Western blotting and MTT assay. The transfected cells were treated with IC50 Cisplatin for 24 h, and the morphological changes of cells were observed using fluorescence, and the cell apoptosis was analyzed using flow cytomerty; the expression levels of proteins related with mitochondrial apoptosis pathway, including caspase-3, cleaved caspase-3, Bcl-2, Bax and cytochrome C (Cyt C), were detected by Western blotting.

RESULTSWestern blotting showed a significantly increased STOML-2 expression in the transfected cells. Overexpression of STOML-2 obviously promoted the proliferation of Siha cells. The STOML-2-overexpressing cells exhibited an obvious resistance to IC50 Cisplatin-induced apoptosis as shown by both fluorescence microscopy and flow cytometry and presented with decreased expressions of cleaved caspase-3, Bax, and cytosol Cyt C and increased expressions of caspase-3, Bcl-2, and mitochondrial Cyt C.

CONCLUSIONSOverexpression of STOML-2 can enhance the proliferation of Siha cells by inhibiting cell apoptosis possibly through the mitochondrial apoptosis pathway.

Objective To assess the prognostic significance of pre-treatment hypercoagulable state in cervical cancer patients. Methods With retrospective analysis, pre-treatment coagulation indicators and platelets from 321 cervical cancer patients from stages I to IV were collected. The pre-treatment coagulation parameters were investigated along with tumor stage and survival data. Result Advanced tumor stage was associated with elevated fibrinogen (Fbg) and platelet (PLT) levels (P < 0.05). Patients with higher levels of Fgb, PTA and PLT suffered from higher risk of recurrence (P<0.05). Multivariate survival analyses showed that tumor stage, Fgb and PTA were independent prognostic factors for disease free survival. Conclusion Coagulation parameters can be served as useful tool for predicting recurrence of cervical cancer.

Objective To evaluate the use of diffusion-weighted imaging(DWI)for early detection of tumor response to Angiostatin-Endostatin(Statin-AE)fusion gene therapy in a rat C6 glioma model.Methods Fifty male wistar rats with C6 tumor cells implanted into the striatum were examined by a 3.0T MR scanner,then the rats beating tmors were divided into two groups,treatment group and control group.Rats in the treatment group received 107 plaque forming unit(pfu)recombinant herps simplex viral (R-HSV)mediated Statin-AE fusion gene therapy on day 7,and then the tumors were conformed on MRI.Conventional MR and DWI examination were acquired on 1,2,3 weeks after implantation with a 5-inch surface coil.Two(1 w),eight(2 w)and all the residual rats(3 w)of each group were sacrificed to perform the histopathological examination after each MBI examination.Pretreatment and post treatment tumor volulnes and apparent diffusion coefficient(ADC)values were calculated.Rank sum test and t test were employed for statistical analysis.Results On MRI,43 rats demonstrated tumors on day 7 with a successful rate of 86%,On week 2,the tumor volumes of the controh and treatment group were 90.6 and 91.64 mm3,with no significant difference(Z=-0.14,P＞0.05).On week 3,the tumor volumes of the controls and treatment group were 156.64 and 29.64 mm3,and a significant difference was observed(Z=-3.45,P＜0.01).On week 2.the ADC values of the tumor centers of the treatment group and the control group were (1.20±0.25)×10-3 and(0.99±0.08)×10-3 mm2/s,and the values of the tumor peripheral parts of the two groups were(1.00±0.25)×10-3 and(0.83±0.12)×10-3mm2/s,the ADC values of both tumor centers and peripheral parts of the treatment group were significantly higher than those of the control group (t=-0.82 and-0.46,P＜0.05).On week 3,the ADC values of the tumor centers of the treatment group and the control group were(0.92±0.21)× 10-3 and(0.99±0.09)×10-3mm2/s,and the values of the tumor peripheral parts of the two groups were(0.81±0.19)×10-3 and(0.78±0.11)×10-3 mm2/a,there were no statisfical difference between the two groups(t=0.82,and-0.46,P＜0.05).HE stained slices showed more prominent tumor interstifial edenla.swelling and death of tumor cells in the treated rats than the controls.Conclusions Combination of conventional MRI and DWI can be powerful to monitor tumor progression and therapy effecL Conventional MRI showed that the therapy slow the tumor progression in size while DWI demonstrated the tumor response even earlier than size change.DWI has potential use forthe detection of early response to antiangiogenic gene therapy.

Objective To investigate the value of application of multi-slice helical CT(MSCT) indiagnosis of basicranial fracture. Methods Sixty-two patients with basicranial fracture were scanned withthin-section scanning mode after conventional CT scanning The images were transferred to the work-station for reconstruction including multiplanar reconstruction (MPR), volume rendering (VR). Comparison between thin-section scanning images and conventional CT scanning images were performed. Results Compared with the conventional CT scanning (67.9% and 45.0% respectively),the rates of fracture displayed of images acquired from thin-section scanning in diagnosis of fractures of anterior and middle cranial fossa (100.0% and 95.0% respectively) ,P＜0.01. The two scanning mode in diagnosis of fractures of posterior cranial fossa( 88.9% and 100.0% respectively )differed from each other unstatistically(P＞0.05 ). ConclusionThe thin-section scanning of MSCT can improve the diagnostic correctness of basicranial fracture.
