Objective To explore the clinical characteristics and risk factors of upper urinary tract stones complicated with non-alcoholic fatty liver disease(NAFLD),so as to provide reference for the prevention of this disease.Methods The clinical data of 158 NAFLD patients undergoing surgical treatment in our hospital during Jan.2022 and Jul.2023 were retrospectively analyzed.According to whether the patients were complicated with NAFLD,they were divided into the NAFLD group(n=56)and non-NAFLD group(n=102).The general data,laboratory indexes and 24-h urinary metabolic indexes were compared between the two groups,and the risk factors were analyzed with univariate and multivariate logistic regression analyses.Results Compared with the non NAFLD group,the NAFLD group had higher BMI[(28.17±4.17)vs.(24.11±3.72),P＜0.001],blood uric acid[(354.13±111.01)μmol/L vs.(294.41±93.72)μmol/L,P＜0.001],and 24-h urinary oxalate level[(37.74±15.00)mmol vs.(27.73±15.27)mmol,P＜0.001].Multivariate logistic analysis showed that BMI(OR=1.311,P＜0.001),24-h urinary oxalate(OR=1.046,P=0.004),and 24-h urinary magnesium(OR=0.599,P=0.002)were the independent factors for NAFLD with upper urinary tract stones.Conclusion NAFLD complicated with upper urinary tract stones is significantly associated with high BMI,high 24-h urinary oxalate,and low 24-h urinary magnesium.

Objective To explore the application value of simple drawing line puncture combined with visual articular process arthroplasty in lateral foraminoscopy.Methods A retrospective analysis was performed on 89 patients with single-segment lumbar disc herniation treated with lateral foraminoscopy from May 2019 to December 2022,including traditional transforaminal endoscopic spine system(TESSYS)technology(conventional group,35 cases)and simple drawing line puncture combined with visual articular process arthroplasty(modified group,54 cases).The fluoroscopy times,puncture time,and operation time of the two groups were compared.The Visual Analogue Score(VAS),Oswestry Disability Index(ODI),and MacNab criteria were used to evaluate the surgical effect at 3 d after surgery and at the last follow-up.Results All the operations were successfully completed without conversion to open surgery.In the conventional group,there was 1 case of L4 nerve root injury,who was considered intraoperative nerve root compression injury.There was no abnormality in lower limb muscle strength after surgery,but hyperalgesia and numbness in the innervated cutaneous area accompanied by nocturnal cramps.The patient was given treatment with pregabalin,mecobalamin,vitamin B1 and B6 for 2 months,and returned to normal at 1 year of follow-up.The other cases had no complications such as dural injury,abdominal organ injury,or incision infection.Recurrence occurred in 1 case in the conventional group and 2 cases in the modified group,and all the 3 cases occurred within 3 months after operation.Among them,2 patients had severe symptoms and underwent endoscopic revision again,and the other patient improved after conservative treatment.Compared with the conventional group,the puncture times[(1.8±0.7)times vs.(7.5±1.1)times,t=27.543,P=0.000].fluoroscopy times[(5.7±1.8)times vs.(23.2±2.2)times,t=41.235,P=0.000]and operation time[(72.7±7.2)min vs.(92.7±7.7)min,t=12.317,P=0.000]in the modified group were significantly reduced or shortened,and there was no significant difference in postoperative hospital stay[(3.2±0.6)d vs.(3.3±0.6)d,t=0.062,P=0.951]between the two groups.The conventional group was followed up for(14.0±1.3)months and the modified group was followed up for(13.6±1.2)months.There were no significant differences in VAS scores[(1.5±0.6)points vs.(1.6±0.7)points,t=0.751,P=0.455].ODI[(10.8±3.4)％vs.(11.8±3.9)％,t=1.284,P=0.202].and excellent and good rate of MacNab criteria[100％(54/54)vs.100％(35/35),Z=-0.981,P=0.327]between the two groups at the last follow-up.Conclusions Simple drawing line puncture combined with visual articular process arthroplasty can significantly improve the accuracy of intervertebral foramen aspiration,with simple operation,reduced X-ray exposure for doctors and patients,shortened operation time,and improved surgical safety.It is worthy of promotion and application in percutaneous foraminoscopy.

Objective:To put forward possible improvement measures through analyzing characteristics of pre-hospital first aid in Ali region and the problems confronted.Methods:The relevant data of pre-hospital first aid in the Emergency Department of Ali People's Hospital of Tibet from September 2015 to August 2019 were collected, and the epidemiological statistics were made. In addition, the number and cycle rule of pre-hospital first aid and the proportion of traffic injuries in pre-hospital first aid in different time periods were analyzed. The isochronous maps were drawn, and the residential areas, tourist attractions and main roads covered by the ground emergency medical service (GEMS) and helicopter emergency medical services (HEMS) at different periods were compared.Results:The epidemiology of pre-hospital first aid was mainly in middle-aged and young patients, accounting for 80.35%. Trauma patients were the most common in both non-native population (45.72%) and local residents, of which traffic injuries accounted for 66.43% of total trauma. Neurological emergency was the second most common among local residents (24.65%), and high altitude reaction was the second most common among non-native population (19.14%). From April to December every year, the amont of emergency treatment in Ali region increased periodically, and reached the peak from July to September. After eliminating the periodic influencing factors, the amount of pre-hospital first aid in Ali region showed a gradual increase over time. The regression equation was Y=15.7+0.27 X, F=36.809, P<0.05, R2=0.444. From April to December every year, the amount of pre-hospital first aid caused by traffic injuries increased significantly ( χ2= 10.819, P< 0.05). Within 15 min, GEMS could cover all the towns in Ali region, as well as the area where the first aid point was located and some villages that were pretty close to the first aid point, with a total of 49 villages (residences); Compared with 15 min, the pre-hospital resources could cover 75 villages (residences) and 4 tourist attractions within 1 h ( χ2 = 10.813, P < 0.05), and the main roads could cover about 788 km. If combined GEMS and HEMS, compared with the coverage of only one hour of ground emergency, the pre-hospital resources could cover 116 villages (residences) and 5 tourist attractions ( χ2 = 19.447, P < 0.05), and the main roads could cover about 1 234 km ( χ2 = 349.532, P < 0.05). Conclusions:HEMS combined with GEMS might fundamentally solve problem of comparatively small coverage of the emergency network in Ali region at present.

Objective:To summarize the surgical treatment of malignant carotid body tumor (MCBT).Methods:A retrospective analysis of 14 MCBT patients admitted at our hospital from Mar 2005 to Nov 2019 was made, and the imaging data, surgical records, perioperative complications and follow-up data were collected.Results:There were 8 males and 6 females, with an average age of (40.8±11.3) years. 10 patients underwent surgical resection of CBT, with one case undergoing tumor enucleation only, nine cases underwent internal carotid artery reconstruction, and all patients underwent intraoperative lymph node biopsy.Tumors were completely removed in all 10 patients. No perioperative death or cerebral infarction occurred. The intraoperative blood loss was (955±658.5) ml. Four patients had permanent nerve injury after surgery. The follow-up time ranged 1-132 months. There were no cases of cerebral infarction or death, and the reconstructed graft remained patent. Apart from the 2 patients who developed tumor metastasis after surgery, other patients recovered uneventfully with no disease progression.Conclusions:Surgery is still the main treatment for MCBT, but MCBT is large and Shamblin class is more advanced. Therefore, complete tumor removal and reconstruction of the carotid arteries are difficult. Surgery should seek to completely remove the tumor and neck lymph node biopsy should be performed to determine the lymph node metastasis.

Objective To investigate the efficacy of microsurgery and predictors of outcome for poor -grade aneurysmal subarachnoid hemorrhage(aSAH).Methods Clinical data of 43 patients of poor -grade aSAH who per-formed microsurgery were retrospectively analyzed.There were 30 patients with Hunt -Hess grade IV and 1 3 patients with grade V.24 patients received emergency operation(within 6hours after onset),1 6 patients received ultra -early operation(within first 24hours after onset).Outcome was assessed by Glascow Outcome Scale(GOS).Results Of 43 patients who received microsurgery,favorable outcome was achieved by 1 9 cases of 43 cases (44.2%),poor outcome was achieved by 1 6 cases of 43 cases (37.2%),the overall outcome of patients with Hunt -Hess grade IV was better than that with grade V(Z =-2.486,P =0.01 6).1 8 patients with intracerebral hematoma received ultra -early or emergency operation,effective surgical intervention(GOS≥3)achieved in 1 2 patients,there was no signifi-cant difference in prognosis between the patients and the others who without intracerebral hematomas(χ2 =0.1 03,P =1 .000).Conclusion The ultra -early or emergency surgery could avoid the risk of aneurysmal re -rupture,relieve malignant intracranial hypertension as soon as possible and decrease the mortality of poor -grade aSAH patients.

Objective To investigate the outcome of microsurgical treatment and its influencing factors in patients with aneurysmal subarachnoid hemorrhage.Methods The consecutive patients with aneurysmal subarachnoid hemorrhage treated with the early or ultra-early microsurgery were enrolled retrospectively.The Glasgow outcome scale (GOS) was used to assess the outcomes of patients at discharge.GOS 4-5 was defined as good outcome,and GOS 1-3 was defined as poor outcome.Results A total of 147 patients with aneurysmal subaraclnoid hemorrhage were enrolled.One hundred and twelve patients (76.2％) had good outcomes.There were significant differences in the proportions of preoperative Glasgow Coma Scale (GCS) scores (12.8 ± 2.8 vs.7.5 ± 3.8;t =7.525,P ＜0.001),low Hunt-Hess grade (83.0％ vs.31.4％;x2 =34.318,P ＜ 0.001),size of aneurysm (x2 =9.531,P =0.009),preoperative rebleeding (6.3％ vs.25.7％;x2 =8.506,P =0.003),preoperative brain herniation (4.5％ vs.40.0％;x2 =26.846,P ＜ 0.001),initial CT scan showing intracerebral hemorrhage (19.6％ vs.48.6％;x2 =11.449,P =0.002),and intraventricular hemorrhage (8.9％ vs.40.0％;x2 =18.846,P ＜0.001) between the good outcome group and the poor outcome group.Multivariate logistic regression analysis showed that the larger aneurysm (odds ratio [OR] 3.194,95％ confidence interval [CI] 1.458-6.999;P =0.004),older age (OR 1.054,95％ CI 1.013-1.097;P=0.010),lower preoperative GCS score (OR 0.539,95％ CI 0.410-0.724;P ＜ 0.001),and preoperative brain herniation (OR 3.633,95％ CI 1.039-12.700;P =0.043) were the independent risk factors for poor outcomes.Conclusions After active surgical treatment,most of the patients with aneurysmal subarachnoid hemorrhage have good outcomes,however,patients with older age,larger aneurysms,lower preoperative GCS scores,and preoperative brain herniation usually have poor outcomes.
