Objective To explore therapeutic effects and indications of stereotatic puncture and drainage under multi-parameter orientation in the treatment of hypertensive intracerebral hemorrhage(HICH).Methods A total of 56 patients with HICH underwent stereotatic puncture and drainage from October 2003 to May 2005.The entrance position,the puncture plane,the puncture angle and depth,and the length of side hole of drainage tube were accurately designed before operation,and,if necessary,multiple drainage tubes were introduced via one hole.Results According to the Glasgow Outcome Scale(GOS) scores,12 patients recovered well(21.4%),29 patients were moderate disability(51.8%),and 12 patients were severe disability(21.4%).No longstanding coma was noted.Three patients died(5.4%). Conclusions Stereotatic puncture and drainage under multi-parameter orientation has better therapeutic effects and less damages than open operation.The procedure is suitable for 10~60 ml hematoma,especially in elderly patients and deep-located hematoma.The best operation timing is 3~6 hours after the onset of hemorrhage.

Objective To explore the clinical value of CT-guided selective radiofrequency thermocoagulation of the semilunar ganglion for the treatment of primary trigeminal neuralgia(PTN).Methods A total of 24 patients with PTN were included.Under local anesthesia and CT guidance,the semilunar ganglion was punctured by way of the oval foramen via the anterior approach using the Hartel's technique.Selective radiofrequency thermocoagulation was performed after the targets were confirmed by electrical stimulation. Results The pain was completely relieved in 18 patients,partially relieved in 5 patients,and unchanged in 1 patient,the total effective rate being 95.8%(23/24).Follow-up observations for 3~18 months(mean,12 months) in the 24 patients showed recurrence in 2 patients(8.3%).Conclusions CT-guided selective radiofrequency thermocoagulation is a safe,simple,and effective option for the treatment of PTN,especially suitable for the elderly and high-risk patients.

Objective To explore the causes of death of patients with cerebral hemorrhage of hypertension in recent 6 years and the countermeasure of decrease death rate.Methods The clinical data,different kinds of treatment and curative effects of the patients of two groups,admitted in recent six years,with cerebral hemorrhage of hypertension was refrospectively analysied.Results Of 157 cases of cerebral hemorrhage of hypertension in group A,there were 69 cases died(44%).Of 158 cases of cerebral hemorrhage of hypertension in group B,there were 48 cases died(30.4%).Death rate between the two of group had significant difference(P

Objective :To explore difference of blood lipid levels among patients with retinal vein occlusion (RVO) from department of ophthalmology , those with hyperlipidemia from department of cardiology and healthy people .Methods :Blood lipid levels were compared among 35 RVO patients who visited department of ophthalmology for the first time ,35 patients with hyperlipidemia who visited department of cardiology for the first time and 35 healthy people undergoing physi—cal examination from Jun 2017 to Jan 2018. Results : (1) Compared with healthy group ,there were significant rise in blood levels of total cholesterol (TC) and triglyceride (TG) ,and significant reduction in blood level of high density lipoprotein cholesterol (HDL—C) in RVO group and hyperlipidemia group (P＜0.05 or ＜0.01) ,and significant rise in blood level of low density lipoprotein cholesterol (LDL—C) in hyperlipidemia group , P＝ 0.001 ; (2 ) Compared with hyperlipidemia group ,there were significant reductions in levels of TC [ (5.73 ± 0.91) mmol／L vs.(5.09 ± 0.83) mmol／L] ,TG [ (2.31 ± 1.37) mmol／L vs.(1.81 ± 1.89) mmol／L] and LDL—C [ (3.11 ± 0.79) mmol／L vs.(2.55 ± 0.42) mmol／L] in RVO group , P＜0.01 all.Conclusion : Blood lipid levels of RVO patients are significantly higher than those of healthy people , but those were reduced than hyperlipidemia group indicated that blood lipid levels rise is a pathogenic factor ,but not only one ,its other pathogenic factor should be investigate .

Objective:To explore the diagnosis and treatment of humeral medial epicondyle fracture combined with radial neck fracture in children and adolescents.Methods:The clinical data were retro-spectively analyzed of the 12 pediatric patients with fractures of the humeral medial epicondyle plus the radial neck who had been admitted from February 2015 to August 2021 to Department of Pediatric Orthopedics, The Second Hospital of Fuzhou. There were 6 males and 6 females, with an age of (11.1 ± 2.5) years. According to the Papavasiliou classification, the humeral medial epicondyle fractures were type Ⅱ in 7 cases, type Ⅲ in 2 cases and type Ⅳ in 3 cases; according to the Judet classification, the radial neck fractures were type Ⅰ in 3 cases, type Ⅱ in 4 cases and type Ⅲ in 5 cases. Two Judet-Ⅰ radial neck fractures were missed by X-ray exam-ination but diagnosed by CT examination. Of the humeral medial epicondylar fractures, 9 were treated by open reduction and hollow screwing and 3 by closed reduction and Kirschner wiring. Of the radial neck fractures, 8 were treated by closed reduction and elastic intramedullary nailing and 4 conservatively. Fracture healing was followed up by postoperative radiographs. At the last follow-up, the carrying angles were measured, Kim Elbow Function Score (KEPS) was used to evaluate the functional recovery of the injured limb, and related complications were recorded.Results:All the 12 patients were followed up for (40.0±25.6) months. Fractures headed after (6.3±1.2) weeks. At the last follow-up, the carrying angle was 15.5°±2.6° on the injured side and 14.7°±2.0° on the healthy side, showing no significant difference ( P>0.05); KEPS was (96.3±5.3) points on the injured side and (98.8±2.3) points on the healthy side, showing no significant difference either ( P>0.05). No incision infection, bone nonunion, elbow valgus, joint stiffness or other complications were found; the postoperative elbow stability recovered well. Conclusions:As the fracture of the humeral medial epicondyle combined with the radial neck fracture is a special type of injury of straightened elbow during valgus stress in children and adolescents, it is likely to be missed in diagnosis. The goal of treatment is good functional recovery by restoring the articular match and elbow stability.

Objective:To evaluate the diagnostic accuracy of the convolutional neural network（CNN） in diagnosing nasopharyngeal carcinoma using endoscopic narrowband imaging. Methods:A total of 834 cases with nasopharyngeal lesions were collected from the People's Hospital of Guangxi Zhuang Autonomous Region between 2014 and 2016. We trained the DenseNet201 model to classify the endoscopic images, evaluated its performance using the test dataset, and compared the results with those of two independent endoscopic experts. Results:The area under the ROC curve of the CNN in diagnosing nasopharyngeal carcinoma was 0.98. The sensitivity and specificity of the CNN were 91.90% and 94.69%, respectively. The sensitivity of the two expert-based assessment was 92.08% and 91.06%, respectively, and the specificity was 95.58% and 92.79%, respectively. There was no significant difference between the diagnostic accuracy of CNN and the expert-based assessment （P=0.282, P=0.085）. Moreover, there was no significant difference in the accuracy in discriminating early-stage and late-stage nasopharyngeal carcinoma（P=0.382）. The CNN model could rapidly distinguish nasopharyngeal carcinoma from benign lesions, with an image recognition time of 0.1 s/piece. Conclusion:The CNN model can quickly distinguish nasopharyngeal carcinoma from benign nasopharyngeal lesions, which can aid endoscopists in diagnosing nasopharyngeal lesions and reduce the rate of nasopharyngeal biopsy.
