Objective:To survey the status of illness and consultation within two weeks among residents in a community in Chengdu.Methods:A multi-stage stratified random sampling was used to carry out a questionnaire survey among the residents in a community in Chengdu during March to April 2019. The disease status, disease severity and consultation within two weeks were surveyed, and influencing factors of two-week illness were analyzed with logistic regression.Results:Among 2 714 participants, 715 had illness (900 times) within two weeks, with a two-week prevalence rate of 26.3%. The main symptoms were dizziness (6.4%, 58/900), cough (6.2%, 56/900), lumbago and leg pain (4.9%, 44/900), palpitations (3.3%, 30/900) and headache (3.1%, 28/900). The three most common diseases were hypertension (38.3%, 345/900), diabetes (19.3%, 174/900) and common cold (6.4%, 58/900). In this survey, the rate of two-week in bed was 20.6‰(56/2 714), and the rate of two-week off work was 4.8‰(13/2 714). Age, gender, education level and work status were the influencing factors of the illness in two weeks ( P<0.05). The choice of medical institution was also different among residents. Conclusion:The survey suggest that primary care should focus on the key groups of residents in the community such as elderly, women, low education level, retirement and unemployed; and it is necessary to strengthen the primary care institutions and two-way referral system of health care.

Objective To evaluate the efficiency and clinical value of modular flexible ureteroscope combined with Holmium laser lithotripsy for treatment of renal calculi. MethodsA total of 46 patients with renal calculi were treated with modular flexible ureteroscope combined with Ho:YAG lithotripsy in our hospital from December 2009 to May 2011.There were 19 cases in middle and upper calyx,8 cases in lower calyx,15 case in renal pelvic,and 4 cases in multiple calyxes.The calculi diameter ranged from 6mm to 31 mm (average in 15 ± 7.9 mm).Flexible ureteroscope was used to find renal calculus under epidural anesthesia,and Holmium laser lithotripsy was used at a maximum energy of 12 to 20W (0.8 - 1.0 J/15 -20Hz).F5 or F6 double-J tubes and catheters were indwelled routinely postoperatively.-examine with KUB and removethe catheter 2 days after operation.Re-examine with B-ultrasonography or KUB 4 weeks after op-eration to evaluate the stone free rate.Residual stones ≥4 mm were regarded as clinical significance of residual stone fragments. Results 45 operations were successful except one case changed to percutaneous nephrolithotomy (PCNL) because of ureteral stricture.The operation time was 45 -150 min (average in 110.4 ±25.3 min).The patients were discharged from hospital in 2 -5 days(average in 3 days) after operation.The stone detection rate was 95.6％ (44/46),and the stone free rate was 86.9％ (40/46) after one operation. No severe complications such as ureteral perforation or hemorrhea occurred. Conclusions Modular flexible ureteroscope combined with Holmium laser lithotripsy is effective and safe for treatment ofrenal calculi,meanwhile it can decrease the high maintenance costs of integrated flexible ureteroscope.

Objective To compare the efficacy and complications of Chinese Shang Ring circumcision with conventional circumcisiom Methods Clinical data of 479 cases of Chinese Shang Ring circumcision and 354 cases of conventional circumcision with complete follow-up were analyzed.Comparisons were made between the two groups on operation time,pain score,blood loss,postoperative complications,postoperative satisfaction with penile appearance,wound healing time and treatment costs. Results There was no statistical difference in age and foreskin status between the two groups (P＞0.05).For the Shang Ring group,the operation time was(5±1)rain,blood loss was (0.98±1.14)ml,pain score during operation was 0.25±0.54,24-hour pain score after operation was 1.63±0.87,the postoperative complication rate was 6.89% (33/479),wound healing time was (20±5)d,the satisfaction rate of appearance was 99.79% (478/479),and treatment cost was (871±52) yuan.For the conventional group,the operation time was (27±5) min,blood loss was (8.30±3.60)ml,pain score during operation was 3.29±1.57,24-hour pain score after operation was 5.56±1.42,the postoperative complication rate was 13.28%(47/354),wound healing time was (13±2)d,satisfaction rate of appearance was 92.37% (327/354),and treatment cost was (554±46) yuan.Compared with the conventional group,the Shang Ring group had a shorter operation time,less blood loss,less pain score,higher appearance satisfaction rate and a lower complication rate (P＜0.05).But wound healing time was longer and treatment cost was higher in the Shang Ring group (P＜0.05). Conclusions Chinese Shang Ring circumcision is simpler and an improved approach over conventional circumeision with shorter operative time,less blood loss,less pain,relatively lower complication rate and higher satisfaction and acceptability.

Objective To investigate the clinical efficacy of short segment fixation with percutaneous pedicle screws or traditional open surgery for the type A1-A3 thoracolumbar compression fracture.Methods A retrospective case control study was conducted on the clinical data of 64 patients with thoracolumbar compression fracture admitted to Shanxi Dayi Hospital between January 2012 and February 2017.There were 44 males and 20 females,aged 21-65 years [(45.4 ± 11.1) years].There was one patient with injured segment at T11,29 at T12,27 at L1 and seven at L2.According to AO typing,there were 39 patients classified as Type A1,two as Type A2 and 23 as Type A3.The patients were divided into minimally invasive surgery group (n =37) and open surgery group (n =27).Minimally invasive surgery group was treated with minimally invasive percutaneous pedicle screw fixation and open reduction.The open surgery group was treated with traditional open pedicle screw short segment fixation and open reduction.The operation time,intraoperative blood loss,total hospitalization time,postoperative hospitalization time,visual analogue scale (VAS) before and after operation,local kyphosis of the fractured vertebra,segmental kyphosis and complications in two groups were recorded.Results All patients were followed up for 12-29 months,with an average of 13.2 months.Between the minimally invasive surgery group and open surgery group,no significant difference was found in the operation time [(106.4± 37.3) minutes vs.(131.3 ± 33.6) minutes] (P ＞ 0.05),and significant differences were found in intraoperative blood loss [(71.2 ± 34.9) ml vs.(409.3 ± 267.5) ml],total hospitalization time [(11.7 ± 7.2) days vs.(21.6 ± 12.8) days] and postoperative hospitalization time [(8.1 ± 7.4) days vs.(16.6 ± 10.6) days] (P ＜ 0.05).In the minimally invasive surgery group,VAS was (6.5 ±1.1) points preoperatively and was (2.3 ± 0.7) points and (1.0 ± 0.3) points immediately after operation and at final follow-up.In the open surgery group,VAS was (6.9 ± 1.0)points preoperatively and was (4.2 ± 1.0) points and (0.9 ± 0.4) points immediately after operation and at final follow-up (P ＜0.05).Compared with the preoperative VAS,those immediately after operation and at final follow-up were significantly decreased within the two groups (P ＜ 0.05).There were no significant differences in the preoperative VAS and VAS at final follow-up between the two groups (P ＞ 0.05),but significant difference was found in VAS immediately after operation between the two groups (P ＜ 0.05).In the minimally invasive surgery group,the local kyphosis of the fractured vertebra was (19.3 ± 3.8) °preoperatively,(3.4 ± 1.7) ° immediately after operation,and (4.6 ± 1.9) ° at final follow-up.In the open surgery group,the local kyphosis of the fractured vertebra was (19.6 ± 6.8) ° before operation,(1.6 ± 0.8) ° immediately after operation,and (2.4 ± 1.1) ° at final follow-up.The kyphosis of fractured vertebra immediately after operation and at final follow-up were significantly decreased within the two groups compared with the preoperative kyphosis(P ＜0.05),but no significant differences were found between the two groups (P ＞ 0.05).In the minimally invasive surgery group,the segmental kyphosis Cobb angle was (16.1 ± 9.1) ° before operation,(3.0-± 1.8) ° immediately after operation,and (5.9 ±1.8) ° at final follow-up.In the open surgery group,the segmental kyphosis Cobb angle was (15.2±12.0) ° before operation,(3.1 ± 1.4) ° immediately after operation,and (5.6 ± 2.1) ° at final follow-up.The segmental kyphosis Cobb angle immediately after operation and at final follow-up were significantly decreased within the two groups compared with the preoperative Cobb angle (P ＜ 0.05),but no significant differences were found between the two groups (P ＞ 0.05).No spinal cord injuries because of pedicle screws were observed after operation in either group.In the open surgery group,there was one patient with wound infection who recovered after dressing change,and no infection case was found in the minimally invasive surgery group.Conclusion For type A1-A3 thoracolumbar compression fractures,both the minimally invasive posterior pedicle screw fixation and the traditional open pedicle screw fixation can achieve satisfactory near-term results,and the former is better in intraoperative blood loss,immediate relief of pain after operation and shorter hospital stay than the latter.

Objective To investigate the therapeutic influence of short segment fixation with navigated percutaneous pedicle screws in the treatment of thoracolumbar compression fracture and whether use of pedicle screw fixation affects the treatment efficacy.Methods A retrospective case control study was conducted on the clinical data of 38 patients with thoracolumbar compression fracture admitted between January 2014 and October 2016.There were 27 males and 11 females,with an average age of 35.9 years (range,21-59 years).There were 14 cases with injured segment at T12,14 cases at L1,and 10 cases at L2,all of which were classified as Type A according to AO typing.The patients were divided into screw group (n =22) and non-screw group (n =16).The pedicle screws were placed into the upper and lower adjacent segments of the fracture vertebra or the fracture vertebra by percutaneous fluoroscopyguided navigation.The operation time,intraoperative blood loss,Visual analogue scale (VAS) before and after operation,anterior vertebral body height,Cobb angle,and complications in two groups were recorded.Results All patients were followed up for 12-30 months,average 15.2 months.No significant differences were found between the screw group and the non-screw group with respect to operation time [(44.7 ±12.6)minutes vs.(39.3 ±11.9)minutes] and blood loss [(56.8 ±13)ml vs.(48.4 ± 11.0)ml](P ＞0.05).In the screw group,preoperative VAS was (6.7 ± 1.5) points,and VAS at postoperative 1 week,six months and 1 year were (2.3 ± 0.9) points,(1.1 ± 0.3) points and (0.9 ± 0.5) points,respectively (P ＜ 0.01).In the non-screw group,preoperative VAS was (6.1 ± 1.7) points,and VAS at postoperative 1 week,six months and 1 year were (2.1 ± 0.8) points,(1.2-± 0.6) points and (1.0-±0.6) points,respectively (P ＜0.01).No significant difference was found on VAS between the two groups (P ＞ 0.05).In the screw group,anterior vertebral body height was (59.5 ±-1 3.6) ％ preoperatively,and anterior vertebral body height at postoperative 1 week,six months and 1 year was (90.6±7.7)％,(89.3 ±8.3)％ and (88.4 ±7.9)％ (P＜0.01).In the non-screw group,preoperative anterior vertebral body height was (60.1 ± 12.5)％,and anterior vertebral body height at postoperative 1 week,six months and 1 year was (89.3 ±8.9)％,(88.4 ±9.1)％ and (86.5 ±8.7)％ (P ＜0.01).No significant difference was found on anterior vertebral body height between the two groups (P＞0.05).In the screw group,preoperative Cobb angle was (15.6 ±4.1)°,and Cobb angle at postoperative 1 week,six months and 1 year was (3.0 ±1.8)°,(5.0 ±1.9) ° and (5.9 ±1.8)°,respectively (P ＜ 0.01).In the non-screw group,preoperative Cobb angle was (16.2 ± 5.1) °,and Cobb angle at postoperative 1 week,six months and 1 year was (3.1 ±1.4)°,(5.2 ±2.3)° and (5.6 ± 2.1) °,respectively (P ＜ 0.01).No significant difference was found on Cobb angle between the two groups (P ＞ 0.05).No spinal cord injuries because of pedicle screws were observed after operation in both groups.Conclusions For thoracolumbar compression fracture,short segment fixation with navigated percutaneous pedicle screws has the advantages of shorter operation time,less bleeding,better postoperative pain relief,and fewer complications.In addition,the postoperative VAS,anterior vertebral body height and sagittal Cobb angle are improved significantly.However,use of pedicle screw fixation in fracture vertebra does not have significant influence on the treatment efficacy.

Objective To explore the clinical efficacy of laparoscopic tumor resection combined with aspiration for central renal angiomyolipoma(RAML).Methods Retrospective analysis of clinical data of 11 patients with central RAML between November 2015 and August 2018,including 8 females and 3 males,aged 35-58 years,mean (45.3 ± 4.8) years;4 cases on the left side,7 cases on the right side,including 4 endophytic tumors,7 exophytic tumors;body mass index (BMI) 22-27 kg/m2,mean (24.9 ±1.8) kg/m2.The maximum diameter of these tumors were 4.2-8.9 cm,with an average of (6.7 ± 2.4)cm.The preoperative serum creatinine was 53-85 μmol/L,with an average of (64.6 ± 16.4) μmol/L,and the glomerular filtration rate (GFR) of the affected side was 42-55 ml/min,with an average of (45.5 ±3.6) ml/min.Lateral kidney function is normal.8 patients underwent retroperitoneal laparoscopic surgery and 3 cases underwent laparoscopic surgery.Based on the preoperative imaging,tumor tissue was aspirated as much as possible by suction device if the tumor got maximal fat component and had not abundant blood supply.Clamp the renal artery in case of bleeding affected the surgery vision.On the contrary,if the tumor had abundant blood supply,the renal artery was clamped first,then removed the section of tumor with scissor and the remaining basal tumor was aspirated totally by suction device.The operation time,warm ischemia time,intraoperative blood loss,postoperative hospital stay,postoperative complications and surgical results were analyzed.Results All the 11 cases were successfully completed without conversion to open surgery,only one case got injury of renal collection system.The operation time was 95-126 min,mean (110.5 ± 12.8) min,and the blood loss was 120-200 ml,mean (155.6 ± 38.4) ml.The warm ischemia time was 22-31 min,mean (27.6 ± 3.3) min,and the postoperative hospital stay was 5-7 days.RAMLs were diagnosed by the postoperative pathological examination.The renal function was normal and no recurrence occurred in these patients at a mean follow-up of 13.9 months.All the 11 cases were successfully completed.Postoperative pathological diagnosis was RAML.There was no complication in the 11 cases.Preoperative serum creatinine and serum creatinine in the first month after surgery [(64.6 ± 16.4)μmol/L vs.(66.7 ± 15.5)tμmol/L,P =0.38] and preoperative renal GFR and GFR in the first month after surgery [(45.5 ± 3.6)ml/min vs.(43.2 ± 3.3) ml/min,P =0.067],the difference was not statistically significant.No recurrence was observed in the 11 cases with an average follow-up of 13.9 months.Conclusions Our initial experience suggests that laparoscopic tumor resection combined with aspiration is a safe,effective and minimally invasive method for the treatment of central RAML.

Objective:To investigate the relationship between discharge readiness and nutritional status of patients undergoing gastric cancer surgery in the context of enhanced recovery after surgery (ERAS) , so as to provide individualized guidance for patients after discharge.Methods:Using the convenient sampling method, a total of 120 patients who underwent radical gastrectomy for gastric cancer from June 2020 to June 2021 in Ningbo First Hospital were selected as research objects, and they all received ERAS nursing care. One day before discharge, Nutritional Risk Screening Table and Discharge Readiness Scale were used for questionnaire analysis.Results:The total score of discharge readiness of 120 patients with gastric cancer after surgery was (81.42±6.87) . Among the three dimensions, personal status was (19.65±2.19) , adaptability was (29.67±3.10) and anticipatory support was (32.10±2.61) . 57.5% (69/120) of gastric cancer patients discharged from hospital had nutritional risk. The scores of hospital discharge readiness and the scores of each dimension in the nutritional risk group were lower than those in the non-nutritional risk group, and the differences were statistically significant ( P<0.05) . Multivariate analysis showed that nutritional status was an influencing factor for the total score of hospital discharge readiness in patients with gastric cancer surgery (standardized regression coefficient was 0.321, P<0.05) . Conclusions:Under the background of ERAS, the discharge readiness of patients after gastric cancer surgery is at a moderate level, postoperative patients are generally at nutritional risk and the discharge readiness of patients with nutritional risk is lower than that of patients without nutritional risk. Perioperative nutrition management by nursing staff can improve the discharge readiness of patients undergoing gastric cancer surgery, and continuous nutrition management should be carried out for discharged patients with nutritional risk, in order to promote home rehabilitation of patients with gastric cancer surgery.

Objective: To investigate the clinicopathologic characteristics and BRAF V600E mutation of brain tumors associated with epilepsy. Methods: Totally 250 patients with brain tumors associated with epilepsy were included from March 2008 to August 2017 retrospectively at Sanbo Brain Hospital, Capital Medical University.The clinical manifestations, histological features and BRAF V600E mutation results were collected and analyzed. Results: There were 132 males and 118 females, and the male to female ratio was 1.1∶1.0. The age of patients ranged from 2 to 67 years(mean 22 years). The tumors had obvious local space occupying effect on MRI. The temporal lobe was the most common site (44.4%, 111/250). There were 58.4% (146/250) of ganglioglioma (GG), 24.0% (60/250) of dysembryoplastic neuroepithelial tumor (DNT), 12.8% (32/250) of pleomorphic xanthoastrocytoma(PXA), 4.0% (10/250) of angiocentric glioma (AG) and 0.8% (2/250) of papillary glioneuronal tumor (PGNT). Mixed GG, PXA and DNT morphological structures were found in 9 of patients. Among 250 cases, 35 cases were accompanied by focal cortical dysplasia(FCD). BRAF V600E was seen in 43 of 74 (58.1%) GG and 13 of 28 (46.4%) PXA. The most common pathologic grade of GG, DNT, AG and PGNT was WHO I. Some of the tumor cells from GG (34 cases) showed higher proliferative activity (WHO Ⅱ/Ⅲ). Most cases of PXA were WHOⅡand high proliferative activity was seen in nine cases. Conclusions The association of low-grade glioneuronal tumors with intractable epilepsy was well-recognized. The most common low-grade glioneuronal tumors were GG.GG may occur in any part of the central nervous system, with a predilection for temporal lobe. Each type of low-grade glioneuronal tumors has its own unique histological morphology, but some may show complex features with 2 or 3 mixed components. The occurrence of BRAF V600E mutations in GG is common, and their detection may be valuable for the diagnosis and treatment in GG.

Objective: To investigate the clinical effect of posterior unilateral short segment screw fixation and bone graft fusion in the treatment of special upper cervical spine injuries. Methods: A retrospective case series study was conducted to analyze the clinical data of 15 patients with upper cervical spine injury admitted to Shanxi Bethune Hospital from July 2012 to May 2017. There were nine males and six females, aged 10-69 years [(41.9±20.9)years]. There were eight patients with traumatic atlantoaxial dislocation, one with congenital atlantoaxial dislocation, two with atlantoaxial dislocation with nonunion of odontoid process, three with Anderson type II odontoid process fracture, and one with old odontoid process fracture. All patients had cervico-occipital pain to different degrees, slender unilateral pedicle and distinct stenosis of vertebral artery. All patients were treated with posterior unilateral screw fixation and bone graft fusion. The injury of spinal cord and vertebral artery, operation time and intraoperative blood loss were recorded. Visual analogue scale (VAS) was used to evaluate pain before and after operation, and Japanese Orthopaedic Association (JOA) score was used to evaluate spinal cord function and postoperative improvement rate before and at the last follow-up. The position of internal fixation and fusion of bone graft were observed by X-ray after operation. Results: All 15 patients were followed up for 6-36 months [(20.4±8.6)months]. All the screws were implanted successfully at the first time, without spinal cord or vertebral artery injury. The operation time was 100-210 minutes [(131.3±32.0)minutes], and the intraoperative blood loss was 100-450 ml [(203.1±104.0)ml]. Preoperative VAS score was (7.9±0.9)points, and postoperative VAS score was (3.7±0.8)points (P<0.01). Preoperative JOA score was (12.1±4.4)points, and the JOA score at postoperative follow-up was (16.1±1.4)points, with the improvement rate of 68%. Postoperative X-ray showed good recovery of cervical spine sequence. One patient developed loosened internal fixation after the neck brace protection was removed one month after surgery, and the patient recovered after timely second surgical fixation and fusion. The remaining 14 patients did not have loosened internal fixation, fracture or loss of reduction, with bone fusion 6-12 months after surgery. Conclusion Posterior cervical unilateral short-segment screw fixation and bone graft fusion can restore cervical stability, relieve pain, and improve function recovery, which can be used as a complementary procedure to treat upper cervical spine injury with anatomic structure variation.

Objective:To explore the relationship between the imaging features of enhanced MRI in patients with central chronic pulmonary artery thromboembolism (CPTE) and pulmonary vascular resistance (PVR).Methods:Thirty-nine patients with CPTE who had contrast-enhanced MRI examination were retrospectively enrolled this study from January 2018 to December 2020. And 33 patients who received right heart catheterization were divided into two groups based on PVR=1 000 dyn·s·cm -5. The differences of imaging features of CPTE in enhanced MRI between the two groups were compared. The relationship between gender, duration of disease, age, pleural thickening, bilateral bronchial artery dilation, number of the involved vascular segments, number of thrombosis, number of the thrombus-related delayed enhancement of artery wall and PVR was analyzed by binary logistic regression. Results:In 39 patients with central CPTE, the dilated lumen (168, 43.30%) and delayed enhancement of wall (122, 31.52%) were found in most of pulmonary arteries. The rate of the lumen dilatation associated with thrombus was the highest among that of the lumen abnormality (66, 52.80%). There were more thrombi in PVR<1 000 dyn·s·cm -5 group than those in PVR≥1 000 dyn·s·cm -5 group (χ 2=9.55, P=0.002). There was no significant difference in the incidence of wall delayed enhancement associated the thrombus between the two groups (χ 2=0.90, P=0.344). The incidence of bilateral bronchial arterial dilatation in PVR<1 000 dyn·s·cm -5 group was higher than that in PVR≥1 000 dyn·s·cm -5 group ( P=0.019). Logistic regression analysis showed that female, the less number of involved vascular segments and bilateral bronchial artery dilation were correlated with the lower PVR. Conclusions:Enhanced MRI is helpful to accurately evaluate the lumen abnormality of pulmonary artery and wall remodeling in central CPTE, which is of great value for the assessment of patients′ conditions and treatment effect.
