Objective To explore the relationship between HPV infection and the incidence of cervical canc-er and precancerous lesions in women.Methods 108 patients with cervical disease who accepted cervical screening were chosen as the research subjects, and they were given colposcopy and pathological examination, hybrid capture 2 generation method for quantitative detection of HPV-DNA content,RLU/CO was used for viral load and HPV-DNA content was more than 1ng/L(RLU/CO>1) can be judged as positive.Results The positive rates of HPV-DNA was 35.00%,67.74%and 95.83%of chronic cervicitis,cervical cancer precursor lesions( CIN) and invasive cervical squamous cell carcinoma,the difference was statistically significant(χ2 =10.73,P<0.05) .The positive rates of HPV DNA in patients with typeⅠCIN,typeⅡCIN,typeⅢCIN were 44.44%,62.50%and 95.00%respective-ly,the difference was statistically significant(χ2 =11.43,P<0.05).HPV-DNA and the positive rate of cervical cancer patients with histological grade,clinical stage,lymph node metastasis,there was no significant correlation(χ2 =1.76,1.44,1.89, all P >0.05 ) .Conclusion HPV -DNA positive rate increased with the severity of cervical lesions in patients,but it had no significant correlation with clinical and pathological parameters,the active prevention of HPV infection of cervical cancer prevention had important significance.

Objective To study the effect of total rhizoma panacis japonica saponins (tRPJS) on hemorheology in rats with occlusion of the middle cerebral artery. Methods Ischemia rat models were made by using the method of thread inserting right middle cerebral artery occlusion. The effects of tRPJS on whole blood viscidity, erythrocyte deformability and erythrocyte congregate in model rats were observed. Results tRPJS 200, 100, 50 mg/kg could significantly improve the erythrocyte deformability, reduce whole blood viscidity and erythrocyte congregate. Conclusion tRPJS can improve the hemorheology after cerebral ischemia. It may be one of the mechanisms for tRPJS in treating ischemic stroke.

Abstract: Objective To analyze the changes of coagulation indicators in patients with hepatitis B complicated with Clonorchis sinensis (C. Sinensis), and provide reference value for diagnosis, drug using and prognosis monitoring. Methods　The patient samples were collected from the Third Affiliated Hospital of Sun Yat-sen University from June 2018 to February 2022 and divided into six groups. They were 40 healthy patients, 47 patients with simple chronic hepatitis B, 47 patients with post-hepatitis B liver cirrhosis, 40 patients with C. Sinensis mono-infection, 30 patients with chronic hepatitis B patients co-infected with C. Sinensis and 27 patients with post-hepatitis B liver cirrhosis patients coinfected with C. Sinensis. Four coagulation indexes, prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT) and fibrinogen (FIB), were detected and compared among the groups. Results Compared with the healthy group, C. Sinensis mono-infection group had higher level of FIB and delayed PT, APTT; chronic hepatitis B group and chronic hepatitis B patients co-infected with C. Sinensis group had delayed PT, APTT, TT and significant lower FIB, these differences were statistically significant (all P<0.05). Compared with simple chronic hepatitis B group, post-hepatitis B liver cirrhosis and chronic hepatitis B patients co-infected with C. Sinensis had significant delayed PT, APTT, TT and lower FIB (all P<0.05). Compared with the post-hepatitis B liver cirrhosis and chronic hepatitis B patients co-infected with C. Sinensis, post-hepatitis B liver cirrhosis patients coinfected with C. Sinensis group had significant delayed PT, APTT, TT and lower FIB (all P<0.05). Conclusions The coinfection of C. Sinensis will further aggravate the coagulation dysfunction of HBV patients, leading to poor treatment and prognosis. HBV patients will have worse coagulation function in the process to post-hepatitis B liver cirrhosis; Therefore, it is important to pay attention to C. Sinensis co-infection when treating HBV patients, so that further guidance on clinical use and monitoring of prognosis can be provided.

Objective To investigate the effects of submucosal resection by guidance under esophageal endoscopic ultrasound. Methods 79 cases ofsuspected upper gastrointestinal submucosal tumors were found by endoscopic ultrasonography,transesophageal endoscopic ultra-sound showed lesions under muscularis mucosa,after informed consent,they were underwent endoscopic mucosal resection. Pathological diag-nose of the lesions were found out after resection. Results Compared with pathological results showed that endoscopic ultrasound accurately determine tumor location in the hierarchy;through endoscopic mucosal resection to remove all lesions,5 patients were found bleeding postop-erative,6 patients were found esophageal stricture,the prognosis was good after treatment. Conclusion Endoscopic ultrasonography can accu-rately determine submucosal myoma,it can be used to guide resection of submucosal myoma.

The Qinghai⁃Tibet Plateau is known as one of the highest endemic areas of echinococcosis However，the dog infection rates of Echinococcus granulosus in the plateau regions were similar to other non⁃Tibetan areas with the high endemic，and most of the rates were below 40%. The infected dogs with E. multilocularis were ubiquitous in Ganzi Prefecture of Sichuan Province and Qinghai Province where many survey data were done and available，which was much different from those in non⁃Ti⁃betan areas where the geographical distribution of dogs infected with E. multilocularis was sporadic. The total infection rates of Echinococcus in dogs kept stable from 1983 to 2009 in Ganzi Prefecture of Sichuan Province and did not show much variation from 2000 to 2014 in Qinghai Province as well. Since 2006，the national comprehensive prevention and control strategy and mea⁃ sures against echinococcosis have been launched in China，and significant progress has been made. In the endemic Tibetan area of Sichuan，the general Echinococcus infection rates in dogs were 28.10%，15.87%，19.22%，3.28% and 1.11% from 2009 to 2013，respectively，and the Echinococcus coproantigen⁃positive rate in Gannan Prefecture of Gansu Province and parts of Qing⁃ hai Province also decreased. This paper reviews the literature on the characteristics of dog infections in the Qinghai⁃Tibetan Plateau，so as to provide useful information to support echinococcosis control and prevention there.

The effects of positive end-expiratory pressure (PEEP) on pulmonary shunt were studied during gen- eral anesthesia and postoperative period.Twenty cholecystectomy patients were randomly divided into experiment group (group P) and control group (group Z). PEEP and ZEEP were used separately after induction. Artery blood and mixed blood from the right ventricle were taken for blood gas analysis and determine the amount of pulmonary shunting before anesthesia. half and hour, one and half an hour and two and half an hour after anesthesia and one hour after the operation.The results showed that shunt in group P decreased gradually during general anesthesia and returned to the level of preoperation at an hour after operation. Shunt in group Z was increased continually and the level was significantly higher than preoperation an hour after operation. Shunt between two groups was significant difference (P

Objective To explore the clinical application and outlook of anterior segment observation with Stratus optical coherence tomography(Stratus OCT).Design Prospective case series.Participants 56 eyes in 38 patients with primary angle closure glaucoma (PACG).Methods Morphological changes of anterior chamber angle (ACA) were observed with Stratus OCT before and 4 weeks after laser iridectomy.Opening status of ACA were described and measured with Photoshop software.Main Outcome Measures Opening degree of ACA and ratio of anterior chamber depth to thickness of cornea.Results To a great deal of extent,Stratus OCT could be used to observe the appearance of ACA. Clear images of ACA could be acquired.The ACA before laser was (15.67?5.33) degree and significantly reopened to(26.56?8.17) degree after laser iridectomy (P=0.000).The ratio of anterior chamber depth to thickness of cornea was also changed from (0.39?0.13) pre-treatment to (0.89?0.32) pest-treatment(P=0.000).Conclusions Stratus OCT could be applied to observe the changes of opening degree of ACA easily.The standard of quantization should be consummated in the future.
