Objective:To present the surgical technique and to evaluate the results of the modified ar-throscopic Latarjet procedure.Methods: Arthroscopic Latarjet procedure has proven to be a reliable method of treatment for difficult anteroinferior instability of the shoulder joint.However, there is no ante-rior capsule reattachment and too much subscapularis damage for the classic procedure.From February 2013 , we modified the classic procedure with reattachment of anterior joint capsule and muscle-tendon junction splitting of subscapularis.Coracoid graft position was evaluated using CT scanning.Results:From March 2012 to August 2014, 51 modified Latarjet procedures were successfully performed arthro-scopically for patients with anterior shoulder instability.According to the CT scanning at the final follow up, the graft was flush with the glenoid in 94.1%, and medially placed in 5.9%.Vertical positioning was perfect in 96.0%(2 to 5 o’clock), too high in 2.0%, and too low in 2.0%.There were no cases of recurrent dislocation or subluxation.Conclusion: The modified arthroscopic Latarjet procedure has shown satisfactory results with good graft positioning.It is a minimal invasive and accurate approach, which combines the advantages of the open procedure.

Objective To investigate clinical effect of surgical repair and reconstruction of traumatic floating shoulder injuries (FSI). Methods Sixteen patients with FSI were treated with open re-duction and reconstructive internal plate fixation. Of all, one patient was with transverse clavicle fracture, six with oblique clavicle fracture and nine with comminuted clavicle fracture. There was one patient with type Ⅰ scapula fracture, three with type Ⅱ, four with type Ⅲ, six with type Ⅳ and two with type Ⅴ. The combined injuries included rib fracture plus hemopneumothorax in six patients, traumatic moist lung in two, craniocerebral injuries in two, hepatic and splenic rupture in two and brachial plexus damage in one. The average time from primary injury to operation was seven days (3-21 days). Results Fifteen out of 16 patients were followed up for 6-28 months (average 11 months). All patients obtained bone u-nion, without infection, loosening or breakage of internal fixation. According to Herscvici evaluation standard of function, the shoulder joint outcome was rated as excellent in 11 patients, good in three and fair in one, with excellence rate of 93%. Conclusion The surgical repair and reconstruction of FSI can, to a greatest extent, recover the anatomical structure and stability around the shoulder joint and shorten the immobilization period of joint, which is beneficial to functional restoration of the joint and de-crease of occurrence of complications.

Objective To investigate the effect of prosthetic replacement for senior patients with unstable intertrochanteric fractures of the femur.Methods Fifty-three senior patients with comminuted intertrochanteric fracture of the femur were subjected to total hip arthroplasty (n =23) and bipolar artificial femoral head replacement (n =30).Uncemented long-stem prostheses were used in 50 patients and cemented long-stem prostheses in 3.Time interval between admission and surgery was 3-13 days (mean 6 days).Results The total hip arthroplasty had the operation time for mean 90 minutes (range,80-110 minutes) and blood loss for mean 350 ml (range,260-410 ml).While the hemiarthroplasty had operation time for mean 65 minutes (range,50-90 minutes) and blood loss for mean 230 ml (range,180-290 ml).Fifty-one patients were available to mean 49.6-month follow-up (range,13-65 months).Four patients presented with frequent hip pain at a tolerable level after hemiarthroplasty and the symptom was relieved after oral non-steroidal anti-inflammatory drug therapy.One patient with postoperative infection was cured by timely debridement.Seven patients were died of heart and brain disorders in 5 years,with no relation to surgical complications.The period for fracture healing was mean 10 months,with excellence rate of 96％ for hip function but with no acetabulum abrasion,implant loosening or submersion.Conclusion Early prosthetic replacement is an effective treatment for unstable intertrochanteric femoral fractures in the elderly.

BACKGROUND:The most effective method for the treatment of acetabular fracture is open reduction and internal fixation, however, this treatment for some special types of acetabular fracture cannot get satisfactory prognosis, and is prone to complications, such as traumatic coxarthrosis and avascular necrosis of femoral head. OBJECTIVE:To evaluate the curative effect of open reduction and internal fixation and total hip arthroplasty in the treatment of special acetabular fracture. METHODS:Twelve cases of acetabular fracture were included, including seven cases of traffic accident wound, three cases of crush injury, and two cases of fal ing injury. The type of bone fracture:two cases of posterior wal fracture, two cases of posterior column and posterior wal fracture, one case of T shaped fracture, five cases of transverse and posterior wal fracture, and two cases of acetabular roof sexual fracture. Complications:one case was femoral head centric dislocation, five cases were latter dislocation, and three cases were caput femoris fractures. Before injury, three cases had coxarthrosis, and two cases were avascular necrosis of femoral head. Al the cases were treated with open reduction internal fixation and total hip arthroplasty, of which nine cases were treated with biological prosthesis, and three cases were treated with bone cement prosthesis. The time from hospitalization to surgery was 3-15 days, and average was 6 days. The patients were fol owed-up once every 2 months in 1 year after replacement, and the Harris score was used to evaluate the hip function recovery. RESULTS AND CONCLUSION:No surgical site and deep wound infection, joint dislocation, lower limb deep vein thrombosis, and death were found in these 12 cases. Among them, 11 cases were fol owed-up for a longtime;the fol ow-up was lasted for 6-82 months. The acetabular fracture was healed at 6-16 months after reduction without prosthesis loosening and sinking. The hip function was evaluated during final fol ow-up according to the Harris score:excellent in eight cases, good in two cases, poor in one case, and the excellent and good rate was 91%. Open reduction internal fixation and one-stage total hip arthroplasty can avoid long-term bed, get out of bed as soon as possible, and reduce complications, thus reconstruct the hip joint painlessly and good functional y.

OBJECTIVE:To investigate improvement effect of external administration of water extract from Eriocarpous Glochidion on chronic dermatitis-eczema model mice, and to provide reference for developing new dermatological drug. METHODS:A total of 60 mice were randomly divided into blank group (distilled water), model group (distilled water), compound triamcinolone acetonide acetate group (positive control group, original liquid) , high-concentration, medium-concentration and low-concentration groups of water extract from Eriocarpous Glochidion(2.0,1.0,0.5 g/mL,calculated by crude drug),10 mice in each group. Except for blank group,other groups were given 2,4-dinitrochlorobenzene to induce chronic dermatitis-eczema model. Since the third day of the experiment,two sides of right ears of the mice were given relevant medicine twice at 7:00 and 15:00,15 μL each time,for consecutive 12 d. In the tenth,thirteenth,sixteenth day of the experiment,the difference of thickness of right ears of the mice was calculated(the difference value before experiment),the times of scratching in ear of mice were recorded within 30 min. In sixteenth day of the experiment,ear swelling degree of mice was determined,and thymus index and spleen index in mice were calculated. Optical microscope was used to observe the pathological changes of ear tissues of mice. RESULTS:Compared with blank group,the difference of thickness of right ears,ear swelling degree,spleen index and scratching times were increased significantly in model group(P<0.05 or P<0.01). The epidermis of the ear tissue was thickened,the cell proliferation was obvious,and cavernous edema was found in the epidermis. Compared with model group,other indexes in were decreased significantly,except that the difference value of thickness of right ears in sixteenth day of the experiment,scratching times in ninth and fifteenth day of the experiment were decreased slightly in low-concentration group of water extract from Eriocarpous Glochidion and the thymus index and spleen index in medium-concentration, low-concentration groups of water extract from Eriocarpous Glochidion (P<0.05 or P<0.01). The pathological changes of ear tissue were improved in administration groups to certain extent. CONCLUSIONS:External administration of water extract of Eriocarpous Glochidion has good improvement effect against chronic dermatitis-eczema in mice, which is worthy of further development and investigation.

Objective:To investigate the influencing factors of reflux esophagitis after sleeve gastrectomy and its plus procedures.Methods:The retrospective case-control study was conducted. The clinical data of 130 patients who underwent sleeve gastrectomy and its plus procedures (jejunal bypass, duodenal-jejunal bypass) for the treatment of metabolic diseases in the First Affiliated Hospital of Nanjing Medical University from May 2010 to August 2021 were collected. There were 34 males and 96 females, aged (32±8)years, with the body mass index (BMI) as (38±7)kg/m 2. Observation indicators: (1) incidence of reflux esophagitis before and after surgery; (2) clinical manifestations of reflux esophagitis and treatment; (3) influencing factors of reflux esopha-gitis after surgery; (4) follow-up. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. In univariate analysis, the median value of clinical variable was used for grouping and the chi-square test was used for subsequent analysis. Multivariate analysis was conducted using Logistic stepwise regression model. Results:(1) Incidence of reflux esophagitis before and after surgery. Of 130 patients, there were 5 cases with Los Angeles classification grade A reflux esopha-gitis before the surgery, and there were 35 cases with reflux esophagitis after surgery, including 26 cases as Los Angeles classification grade A esophagitis, 8 cases as Los Angeles classification grade B esophagitis and 1 case as Los Angeles classification grade C esophagitis. There was a significant difference in the incidence of reflux esophagitis for patients before and after surgery ( P<0.05). (2) Clinical manifestations of reflux esophagitis and treatment. The 5 patients with preoperative reflux esophagitis described with no obvious heartburn and acid regurgitation and did not receive treat-ment. For the 35 patients with postoperative reflux esophagitis, 22 cases described with heartburn and acid regurgitation, and 13 cases described without any symptoms. Of the 35 patients, 10 were treated with continuous oral proton pump inhibitors, 2 were treated with intermittent oral proton pump inhibitors, 10 were relieved by dietary adjustment, and 13 were not treated. For the 95 patients without postoperative reflux esophagitis, 5 cases described with heartburn and acid regurgitation, requiring continuous oral proton pump inhibitor treatment. The remaining 90 cases described no heartburn and acid regurgitation and did not receive treatment. (3) Influencing factors of reflux esophagitis after surgery. Results of multivariate analysis showed that the preoperative reflux diagnostic questionnaire scoring >0 and the occurrence of postoperative heartburn and acid regurgi-tation were independent risk factors of postoperative reflux esophagitis ( odds ratio=7.84, 47.16, 95% confidence interval as 2.04?30.20, 11.58?192.11, P<0.05). (4) Follow-up. All 130 patients were followed up for 17(range, 12?60)month after surgery. The BMI, percentage of total weight loss, diabetes remission rate, fasting blood glucose and glycosylated hemoglobin of the 130 patients at postoperative 12 month were (25±4)kg/m 2, 31%±8%, 84.6%(22/26), (5.6±1.2)mmol/L and 5.9%±1.3%. Conclusions:The sleeve gastrectomy and its plus procedures increase the risk of postoperative reflux esophagitis. Preoperative reflux diagnostic questionnaire scoring>0 and the occurrence of postoperative heartburn and acid regurgitation are independent risk factors of postoperative reflux esophagitis. Dietary adjustment and proton pump inhibitor therapy can alleviate symptoms of reflux esophagitis, but cannot cure reflux esophagitis.

【Objective】 To supervise the clinical blood use of 19 hospitals, covering a district of Shanghai, during two years, and discover the problems in the process of blood transfusion, so as to put forward suggestions for corrective methods in grades and promote continuous improvement of clinical transfusion management. 【Methods】 A total of 19 hospitals were supervised in terms of hardware facilities, management level, professional and technical level, and blood typing test on the site, according to the Administrative Blood Management Measures for Medical Institutions, Technical Specification for Clinical Transfusion and Shanghai Medical Quality Supervision Score Statistical Table.All data were analyzed. 【Results】 These hospitals can properly perform clinical blood transfusion, but there were obvious differences.Tertiary hospitals were relatively better, yet need to strengthen the management of medical documents.Secondary hospitals remained to be improved, mainly in insufficient construction of Blood Transfusion Department (blood bank), the lack of management and maintenance of key equipment and the lack of standardization in medical documents writing.However, flaws in the supervision were general in private hospitals (most of which were affiliated hospitals), so the management of clinical blood use should be further strengthened. 【Conclusion】 For secondary hospitals or above, routinized writing of medical documents and promoted construction of Blood Transfusion Department (blood bank) should be strengthened.For private hospitals, especially affiliated hospitals, the management of clinical blood use should be further improved, including the examination rules corresponding to the blood use process and strict access and exit mechanism, so as to improve the overall management level of clinical blood use and ensure the safety of clinical blood use.

OBJECTIVETo evaluate and compare the clinical and radiographic outcomes of both acute and chronic two-part lesser tuberosity fracture with locked posterior dislocation and analyze the risk factors for the clinical outcomes.

METHODSBetween April 2003 and June 2010, 29 patients received surgical treatment for two-part lesser tuberosity fractures with a locked posterior shoulder dislocation. Eighteen of these patients received modified McLaughlin procedures and were available for both clinical and radiographic evaluation for more than 2 years. All of the 18 patients were male. The average age was (40 ± 11) years (range, 21-58 years). Nine patients had left arms involved while another 9 patients got right side involved, 9 of 18 patients had their dominant side involved. The average time from initial injury to surgery was (40 ± 42)days (range, 4-123 days). The patients received follow-up 3 months, 6 months and 1 year after the operation, and the follow-up was performed once a year. The shoulder range of motion and visual analogue scale (VAS) were recorded at the final follow-up. The functional outcomes were evaluated using University of California-Los Angeles Shoulder Scale (UCLA), Constant Score, and American Shoulder and Elbow Surgeons Shoulder Score (ASES). The degree of humeral head necrosis was analysed according to plain radiographs taken at the final follow-up. The risk factors including patients' age, dominant side involvement and time from injury to surgery on the final clinical outcomes and the degree of humeral head necrosis were also analysed using Pearson correlation analysis and Wilcoxon analysis methods.

RESULTSThe mean follow-up period was (38 ± 16) months (range, 24-72 months). All of the patients regained shoulder stability postoperatively. At the final follow-up, the average VAS was 0.6 ± 0.9 (0-3). The average UCLA was 28 ± 4 (23-33). The average Constant was 85 ± 8 (71-96). The average ASES was 83 ± 7 (75-95). The time from injury to surgery was identified as the risk factor regarding UCLA (r = 0.648, P = 0.004), Constant score (r = 0.506, P = 0.032) and ASES score (r = 0.517, P = 0.028).

CONCLUSIONSSatisfactory results can be achieved with surgical treatment for lesser tuberosity fractures with locked posterior shoulder dislocations. The time from injury to surgery has a negative impact on the clinical function outcome.
