To report a case of clonorchiasis (Clonorchis sinensis infection) combined with intrahepatic cholangiocarcinoma and review relevant literature to improve the awareness of the clinical physicians regarding Clonorchis Sinensis and provide references for clinical diagnosis and treatment. A retrospective analysis was conducted on a case of clonorchiasis combined with intrahepatic cholangiocarcinoma, admitted to Guangzhou Red Cross Hospital of Jinan University on March 15, 2021, along with a review of related literature. The patient, a 55-year-old male, presented with abdominal distension and poor appetite for over two months and had a history of diabetes and hypertension for many years. He had been consuming raw fish for more than ten years. Upon admission, physical examination revealed a solid mass measuring 8 cm×8 cm was palpable below the xiphoid process in the upper abdomen, with an uneven surface, slightly hard texture, poor mobility, and positive tenderness. Laboratory tests revealed the presence of Clonorchis Sinensis eggs in the stool, and the patient tested positive for Clonorchis Sinensis IgG antibodies. After a comprehensive evaluation that included abdominal ultrasound, abdominal plain CT scan, and contrast-enhanced CT, the patient was diagnosed with "intrahepatic cholangiocarcinoma with multiple intrahepatic metastases." Due to the patient's poor liver function, praziquantel was not administered, and albendazole was instead used at a dose of 10 mg/(kg·d) once daily for seven days. Upon re-admission one month after discharge, no Clonorchis Sinensis eggs were found in the stool. A follow-up after 12 months revealed that the patient had passed away due to liver failure. The serious infection of Clonorchis Sinensis is relatively rare, but it can lead to severe consequences in high-risk individuals, especially when it progresses to intrahepatic cholangiocarcinoma. Clinicians should enhance their awareness of clonorchiasis and promptly identify and provide symptomatic treatment for infections, as early as possible and provide appropriate treatment. Early diagnosis and treatment are crucial for improving the prognosis of patients.

Objective To establish gastric bypass surgery model with SD rat and analyze the influence factors and preventive measures so as to accumulate experience and skills for further developing gastric bypass surgery model on diabetic rat( GK rat) . Methods Gastric by-pass surgery was operated on 30 SD rats. Summarized modeling experience and analyzed various factors affecting modeling success. Results 17 rats weresuccessfully survived after surgery and 13 failed, with the mortality rate 43. 3%. Three rats died during operation, including two for anesthesia and one for heart failure;one died due to anastomotic bleeding two hours after surgery. Eight died in the third day after surgery, including two for infection, two for intestinal necrosis, four for anastomotic stenosis or obstruction. One died because of anastomotic leakage caused by mistaking and satiety the fifth day after surgery. There were no other complications such as wound dehiscence occurred in this group . Conclusion Establishing models of gastric bypass surgery with SD rats which is regarded as pre-experiment of building models of gas-tric bypass surgery with GK rats is economical and feasible. Anesthesia and perioperative management, surgical techniques and infection pre-vention and control are the main factors affecting modeling. The survival rate of rat model could be increased if related factors well controlled.

Objective To analyze the GDM of 336 cases with chronic HBV in pregnancy. Methods According to HBV DNA≥1.0 × 103 IU/mL, participants were divided into HBV DNA (+) or (-) group. 409 cases without HBV were selected as control group. Differences on GMD incidence between groups and virus load and OGTT blood sugar correlation were compared. Results The incidence of GDM of HBV DNA (+) or (-) group was 16.77% and 17.71%, which is higher than that in HBV group (10.27%). The difference is significant (P < 0.05). The correlation index between HBV DNA and fasting blood-glucose is r = 0.005, P = 0.610, the result of which is not statistically significant. But correlation index between HBV DNA and blood sugar at 1 h , 2 h are r = 0.082, 0.086; P = 0.000, 0.000, the result of which is statistically significant. Conclusion The oc-currence of GDM were higher in HBV DNA (+) or (-) group. The viral load is positively related with blood sugar of glucose tolerance at 1 h or 2 h.

Objective To investigate the curative effect and nursing of medical ozone autohemotherapy in clinical treatment. Methods 45 cases of cerebral infarction patients with medical ozone self blood therapy spells, psychological guidance and health education before operation in the sterile operation, postoperative nursing, education results. Results 45 cases of cerebral infarction in patients with very good completed treatment, 2 cases because of dizziness aggravated, 2 cases of vascular puncture for difficult to stop treatment, the rest were different extent achieved certain effect. Conclusions the clinical experiment showed that the nursing, preoperative education, psychological guidance and sterile operation, postoperative is an effective measure for ensuring medical ozone autohemotherapy smooth finish.

Objective: To evaluate the feasibility and effect of transcatheter closure of ventricular septal defects(VSD) using the VSD occluder.Methods: From December 2003 to March 2005,13 VSD patients,8 males and 5 females,ranging in age from 4 to 35(15.2?10.7)years,underwent catheter closure using the VSD occluder.Tthe mean diameter of the VSD obtained by transthoracic echocardiography was 4-12(5.4?1.2) mm.Transcatheter closure was performed under transthoracic echocardiographic guidance after left ventriculography.All patients were followed up 1,3 and 6 months after the procedures. Results: The devices were successfully placed in 12 of the patients and complete closure achieved in 11.Trace residual shunt was observed in 1 patient but disappeared within 10 minutes.No severe complications were noted except 1 case of complete right bundle branch block revealed by electrocardiography. Conclusion: Transcatheter closure of VSD by the VSD occluder is a safe and effective procedure,with good immediate results.Further clinical trials are under way to assess its long-term effect.
