Objective: To study the effective treatment methods of arteriovenous malformation(AVM) in jaw bone through retrospective review. Methods:33 patients with jaw AVM were analyzed by history, treatment methods and outcome. Results: Among the 33 patients 6 were treated by embolization only, 12 by curretting, 10 by resection of the bone lesions. The cure rate in the three groups was 2/6,11/12 and 10/10 respectively. Conclusions: Embolization combined with curretting may be the effective methods to treat facial bone AVM without resection of bone.

ObjectiveTo investigate the correlation between the surgical effect and clinical factors in retinal detachments with macular hole patients.Methods71 patients were picked up from the rhegmatogenous retinal detachment (RRD) database in our hospital. All patients were well informed with clinical data and followed up. Logistic regression statistical analysis was performed to analyze correlation between the effect of operation and clinical factors.ResultsAll patients obtained successful retinal replacement and macular hole closure, but retinal detachment was relapsed in 10 patients from 3 days to 3 years after operation. Effect of retinal replacement was related with proliferative vitreoretinopathy (PVR) grade and course (P<0.05), while eyesight improvement was related with PVR grade, age and course (P<0.05).ConclusionAge, PVR grade and course affect the surgical effect.

Objective: To compare the expression of multidrug resistant gene( mdr 1 ) in oral squamous cell carcinoma (SCC) before and after chemotherapy. Methods: Mdr 1 gene expression in 21 cases of oral SCC was detected before and after chemotherapy by dot blot hybridization, Results: Before and after sigle drug chemotherapy mdr1 mRNA(?10 5 copies/?g) in SCC tissue was 1.98?1.72 and 3.74?3.24( P

Objective:To study the relationship between preoperative serum carbohydrate antigen 19-9 (CA19-9) levels and long-term prognosis after partial hepatectomy in patients with hepatocellular carcinoma (HCC).Methods:The clinical data of 1102 patients with HCC who underwent partial hepatectomy at the Affiliated Tumor Hospital of Guangxi Medical University from January 2012 to December 2017 were retrospectively analyzed. There were 960 males and 142 females, with an average age of 51 years. The X-tile software determined the best cut-off value of CA19-9 to be 55U/ml. The enrolled patients were then divided into the low-level (CA19-9≤55 U/ml, n=956) and high-level (CA19-9 >55 U/ml, n=146) groups. The Kaplan-Meier method was used to analyze survival, and the log-rank test was performed to evaluate survival rates. The prognostic risk factors of HCC were calculated by the Cox proportional hazards model. Results:The 1, 3, and 5-year survival rates for the low-level group were 85.0%, 68.2%, and 60.9%, respectively, which were significantly higher than those of the high-level group of 80.1%, 58.2%, and 47.0%, respectively ( P<0.05) . The 1, 3, and 5-year recurrence-free survival rates of the low level group were 60.5%, 44.6%, and 37.9% respectively, which were significantly higher than those in the high-level group of 53.4%, 33.3%, and 25.1%, respectively ( P<0.05). Cox regression analysis showed that patients with CA19-9 >55 U/ml ( HR=1.323, 95% CI: 1.070-1.636, P=0.010) had a higher risk of recurrence after hepatectomy, while patients with CA19-9 >55 U/ml ( HR=1.511, 95% CI: 1.163-1.964, P=0.002) had a poor prognosis after hepatectomy. Conclusions:Preoperative serum level of CA19-9>55 U/ml was an independent risk factor for survival and recurrence of HCC patients after partial hepatectomy. CA19-9 had a significant predictive value for prognosis of HCC patients who underwent partial hepatectomy.

Objective To establish the animal model with stress ulcer(SU) and probe the relationship between the gastric mucosal injury and lasting stress time,the dynamic structural changes of pH of gastric juice.Methods Twenty-four SD young rats were randomly divided into 4 groups:control group,45 min(groupⅠ),90 min(groupⅡ),3 h(groupⅢ)groups under water immersion restraint stress(WRS).The change of gastric mucosal ulcer index(UI),pH of gastric juice were observed.Results Acute gastric mucosal damage was induced by WRS,with the WRS time prolonged,UI increased gradually and pH of gastric juice remarkably decreased in experimental rats.UI was positively rela-ted with stress time(r=0.957 P

OBJECTIVE: To discuss the diagnosis and treatment of esophageal perforation induced by esophageal foreign body. METHOD: Ten patients, who were diagnosed as esophageal foreign body and esophageal perforation, were retrospectively analyzed. One patient was operated in other hospital and transferred to our department post-operation. The foreign bodies were removed through rigid esophagoscope in 7 cases and through the tracheotomy in 1 case. The last case was admitted into hospital for abscess around the esophagus. The foreign body wasn't find during the examination of rigid esophagoscope and the patient vomited out a glass foreign body after the surgery. RESULT: In all cases, there were three date stones, two button batteries, one metal gear, one pin, one metal cans pull ring, one glass plate, one arc hard plastic sheet. Seven patients were cured after conservative treatment, and restored normal diet. For the rest 3 cases, patients were cured after the repair operation of tracheoesophageal fistula. CONCLUSION The esophageal perforation must be highly suspected of the esophageal foreign body with a long history, sharp shape or corrosive foreign body. The esophageal radiography may be taken to obtain the final diagnosis. The patients diagnosed as esophageal perforation must be treated with antibiotics, nasal feeding or feeding by gastrostomy, and followed-up closely. Small perforation can heal after a period of time by nasal feeding, while tracheoesophageal fistula was needed to repaire after a period of time for restoring a good physical condition in most cases.

Objective: To investigate the prevalence of Internet addiction among primary and middle school students in Jiaxing City, so as to provide insights into the development of interventions for Internet addiction among primary and middle school students. Methods: A total of 1 701 students were sampled from two primary schools, two junior high schools, two senior high schools and two vocational high schools in Jiaxing City during the period between September and October, 2021, using the stratified cluster sampling method. The Internet addiction status was evaluated using the Internet Addiction Test, and the depression status was tested using the Patient Health Questionnaire-9 (PHQ-9), while the anxiety was assessed with the Generalized Anxiety Disorder Scale (GAD-7). Results: The participants included 783 men (46.03%) and 918 women (53.97%), and 873 rural students (51.32%) and 828 urban students (48.68%). The overall detection of Internet addiction was 6.53% among the participants, and the prevalence of moderate and severe Internet addiction was 5.88% and 0.65%, respectively. A higher prevalence of Internet addiction was detected in rural students (χ2=4.695, P<0.05), junior high school students (χ2=65.337, P<0.05), students with a poor relationship with family members (χ2=39.231, P<0.05), teachers (χ2=28.799, P<0.05) and classmates (χ2=36.341, P<0.05). The prevalence of depressive and anxiety symptoms was 23.81% and 21.52%, respectively, and the prevalence rates of depressive and anxiety symptoms were both higher among primary and middle school students with Internet addiction (68.47% and 56.76%) than among those without Internet addiction (χ2=130.556 and 87.327, both P<0.05). Conclusion The prevalence of Internet addiction is high among primary and middle school students living in rural areas and with poor interpersonal relationships in Jiaxing City. Students with Internet addiction are more likely to develop depressive and anxiety symptoms.

Objective To observe the anti-aging effect of Yinao capsule. Methods The rat model of acute incomplete cerebral ischemia was established, and determined the content of superoxide dismutase (SOD), lipid peroxidation (LPO) and Evans blue in brain tissue, determined the serum SOD content of normal rats. Formed blood platelet thrombus by common carotid artery-external jugular vein blood flow bypass operation of rats, and weighed wet weight of thrombus. Results The Yinao capsule can increase SOD and Evans blue content of brain tissue from rat model of acute incomplete cerebral ischemia, at the same time, decrease the LPO content. It can enhance serum SOD content of normal rats, and inhibit the formation of experimental thrombus. Conclusion The Yinao capsule can prevent the occurrence of senile diseases, and defer organism aging.
