Objective To investigate clinical efficacy and side effects of long-acting risperidone microsphere injection for treatment of patients with schizophrenia. Methods A total of 82 patients with schizophrenia were randomly divided into two groups,study group with long-acting risperidone microsphere injection and control group with atypical antipsychotics treatment for 24 weeks. The Positive and Negative Syndrome Scale (PANSS),The Personal and Social Performance (PSP) and Treatment Emergent Symptoms Scale (TESS) were used to evaluate efficacy and adverse effects of treatment at the end of 1st ,2nd,4th, 12nd and 24th week. Results The therapeutic efficacy in control group was similar to that in study group,and there was no significant difference between the two groups (P＞ 0.05 ). But the therapeutic efficacy in study group was better than that in control group at the end of the 4nd week (P＜0.05 ) , and study group was more likely to improve social function(P ＜ 0. 05 ). Incidence of adverse effects in study group was lower than that in control group , but the difference was not significant (P ＞0.05 ). The incidence of akathisia symptom in study group was higher than that in control group,but the difference was not significant (P＞0.05). The incidence of drowsiness symptom in study group was significantly lower than that in control group(P＜0.05 ). Conclusion Long-acting risperidone microsphere injection is as effective as atypical antipsychotics for treatment of patients with schizophrenia, but it has better efficacy in improving social function of the schizophrenia with lower side effects.

Objective To observethe clinical efficacy of comprehensive acupuncture treatment in treating primary open-angle glaucoma, and to objectively evaluate the therapeutic efficacy.Method Twenty-eight patients (53 eyes) who received acupuncture treatment were recruited. By adopting a self-control design, the changes of intraocular tension, mean defect (MD) of vision field, mean sensitivity (MS), vision, and score of Quality of Life Scale for Patients with Visual Impairment (QLSPVI) were observed after 3-month acupuncture treatment.ResultThe intraocular tension of the 28 patients declined obviously after the treatment (P<0.01); MD, MS and vision didn't show significant improvements after the treatment (P>0.05); the QLSPVI score dropped significantly after the treatment (P<0.01);the total effective rate was 86.8%; the therapeutic efficacy wasn't correlated with age, disease duration, and treatment duration (P>0.05).Conclusion Acupuncture treatment can effectively reduce the intraocular tension, control the deterioration of MD and MS, maintain the level of vision, and enhance the quality of life of patients with primary open-angle glaucoma; with the same disease duration, the longer the treatment, the better the therapeutic efficacy.

Objective To compare the safety of laparoscopic live donor nephreetomy(LDN) and open live donor nephrectomy(ODN), evaluate the kidney function and blood pressure of living donors during 1 year follow-up. Methods Thirty cases of LDN and 30 eases of ODN were retrospectively reviewed. The operation time, warm ischemia time, operative blood loss, time to post-operative intake and time to ambulation of the 2 grouups were compared. According to the modified Clavien classifica-tion system procedure-related complications were described and compared. Serum creatinine(SCr) le-vels, blood pressure and 24-h urine protein excretion were measured before nephreetomy and 1 d, 7 d, 3 months, 6 and 12 months after nephrectomy. Glomerular filtration rate (GFR) were measured preo-pratively and at 6 and 12 months postoperatively. These data were statistically analyzed. Results The operation time was (98. 6+13. 6)rain and (96.3+19. 5)rain in the LDN and ODN groups, re- spectively. Warm ischemia time in the LDN group was (90.6±15.1)s, in the ODN group was (86.4±12.3)s. Operative blood loss was (105.2±634.8)ml and (206.3±126.4)ml in the LDN and ODN groups(P<0.01). For the time to post-operative intake and time to ambulation, LDN group was (28.5±2.9)h and (25.8±63.8)h, ODN group was (38.6±63.3)h and (36.5±65.3)h(P<0.01). Perioperative complications rates were 6.6%(2/30) and 23.3%(7/30) for LDN and ODN, respective-ly. SCr was (109.1±7.5), (105.4±69.5), (96.6±10.7), (89.4±11.5), (91.6±69.3)/zmol/L in the LDN group and (107.3±69.6), (103.3±68.4), (95.4±69.1), (90.5±13.6), (90.3±11.7)μmol/L in the ODN group 1 day, 7 days, 3 months, 6 months and 12 months after nephrectomy. The mean GFR of LDN and ODN was 64.7 and 65.8 ml/min at 6 months after nephrectomy, 65.9 and 67.5 ml/min at 12 months postoperatively, which were significantly different comparing with preoperative mean GFR in each group(P<0.05) but no significant difference was found between 6 months and 12 months after nephrectomy and between the 2 groups at the same time point respectively(P>0.05). Mean 24 h protein excretion was elevated after either LDN or ODN during 1 year followup, but was not significantly different either between predonation and 1 year after nephrectomy or between the 2 groups at the same period. Blood pressure increased or decreased slightly with the duration of follow-up,no significant blood presure changes were found before and after nephrectomy or between the two groups at the same period postoperatively. Conclusions LDN has the advantages of minimal trauma, less operative blood loss and quicker convalescence. It is safe and and has no adverse effects regarding kidney function and blood pressure during the first year after living kidney donation comparing to ODN.

BACKGROUNDThe mini-invasive surgery is now performed widely and these operations have been used in complete resection of lung cancer. The aim of this study is to summarize the results and to explore practicability of bronchial sleeve resection and reconstruction of pulmonary artery by video-assisted thoracic small incision surgery for lung neoplasms.

METHODSA total of 109 patients were retrospectively reviewed, who underwent sleeve lobectomy and bronchoplasty by video-assisted thoracic small incision surgery for lung neoplasms from January 1995 to December 2005.

RESULTSOperations were performed successfully for all the patients. The small incisions' length ranged from 3 to 15 cm and the mean length was 10 cm. The surgical time was 125-180 min and the mean was 150 min; blood loss was 210-450 mL and the mean was 320 mL. There was no operative mortality, occurrence of anastomosis stenosis and fistula. Follow-up results showed that there was no sign of re-perfusion hurt and no edema in remaining lobes. There was no blood transfusion in 80.7% of cases (88/109), no shoulder hurt in 94.5% of cases (103/109). The stay in hospital was 7-15 days, and the average was 9 days.

CONCLUSIONSThe bronchial sleeve resection and reconstruction of pulmonary artery by video-assisted thoracic small incision surgery for lung cancer could finish the same work as traditional thoracic lateral incision, with less trauma, less bleeding and blood transfusion, less time in opening and closing thorax.

Objective:To explore the value of fast susceptibility weighted imaging (SWI) generated by a deep learning model in assessment of acute ischemic stroke (AIS).Methods:From January 2019 to January 2021, 118 AIS patients [75 males and 43 females, aged 23-100 (66±14) years] who underwent MR examination and SWI sequence scanning within 24 h of symptom onset in the First Medical Center of PLA General Hospital were retrospectively analyzed. MATLAB ′s randperm function was used to divide 118 patients into a training set of 96 cases and a test set of 22 cases at a ratio of 8∶2. Fourty-seven AIS patients [38 males and 9 females, aged 16-75 (58±12) years] from one center of a multicenter study were selected to build the external validation set. SWI image and filtered phase image were combined into complex value image as full sampling reference image. Undersampled SWI images were obtained by retrospective undersampling of reference fully sampled images, and the undersampling multiple was five times which could save 80% of the scanning time, then the complex-valued convolutional neural network (ComplexNet) was used to develop reconstruct fast SWI. Interclass correlation coefficient (ICC) or Kappa tests were used to compare the consistency of image quality and the diagnostic consistency for the presence of susceptibility vessel sign (SVS), cerebral microbleeds and asymmetry of cerebral deep medullary veins (DMVs) in AIS patient on fully sampled SWI and fast SWI based on ComplexNet.Results:In test set, score of image quality was 4.5±0.6 for fully sampled SWI image and 4.6±0.7 for fast SWI based on ComplexNet, and coefficient was excellent (ICC=0.86, P<0.05). Full sampling SWI had good agreement with fast SWI based on ComplexNet in detecting SVS (Kappa=0.79, P<0.05), microbleeds (Kappa=0.86, P<0.05), and DMVs asymmetry (Kappa=0.82, P<0.05) in AIS patients. In the external validation set, score of image quality was 4.1±1.0 for fully sampled SWI image and 4.0±0.9 for fast SWI based on ComplexNet, and coefficient was excellent (ICC=0.97, P<0.05). Full sampling SWI had good agreement with fast SWI based on ComplexNet in detecting SVS (Kappa=0.74, P<0.05), microbleeds (Kappa=0.83, P<0.05), and DMVs asymmetry (Kappa=0.74, P<0.05) in AIS patients. Conclusions:Deep learning techniques can significantly accelerate the speed of SWI, and the consistency of image quality and detected AIS signs between fast SWI based on ComplexNet and fully sampled SWI is good. The fast SWI based on ComplexNet can be applied to the radiographic assessment of clinical AIS patients

OBJECTIVETo compare the clinical efficacy of treating different diseases with the same acupuncture comprehensive therapy and intramuscular injection of ranibizumab in the treatment of macular edema, and to explore an effective treatment.

METHODSA retrospective study was conducted, ①Acupuncture combined with EA at Xinming one (Extra), Sizhukong (TE 23), Tongziliao (GB 1), once every other day; ②acupoint injection, alternation with compound anisodine and mecobalamine injection at Qiuhou (EX-HN 7), Taiyang (EX-HN 5), once every other day; ③auricular acupressure at yan (LO), gan (CO), shen (CO) and other points; ④plum-blossom needle at Zhengguang 1 (Extra), Zhengguang 2 (Extra), once every other day were given in the acupuncture group (20 cases, 24 affected eyes). Intramuscular injection of 0.5 mg ranibizumab was given in the ranibizumab group (22 cases, 23 affected eyes). The macular foveal thickness, early treatment diabetic retinopathy study of (ETDRS) visual acuity chart, self-evaluation scores of visual function impairment ophthalmopathy patient's quality of life scale were observed before treatment, after 3, 6, 9 and 12 months of treatment, and the clinical efficacy was evaluated.

RESULTS①At all the observation time points of the treatment, the macular thickness was lower than that before treatment in the two groups (all <0.05), and there was no significant difference between the acupuncture group and the ranibizumab group (all >0.05). ②Visual acuity was higher than that before treatment at all the time points in the two groups (all <0.05). After 3-months treatment, there was no statistical significance between the two groups (>0.05). After 6, 9, and 12 months treatment, the visual acuity in the acupuncture group was better than that in the ranibizumab group (<0.05, <0.01). ③At all the time points, the quality of life scores were lower than those before treatment in the two groups (all <0.05). There was no statistical significance in the ranibizumab group compared with those before treatment (all >0.05). In 3, 6, 9 and 12 months of treatment, the quality of life scores in the acupuncture group was better than those in the ranibizumab group (<0.05, <0.01). ④The total effective rate of the acupuncture group was 79.2% (19/24), which was better than 30.4% (7/23) in the ranibizumab group (<0.05). ⑤The improvement of visual acuity before and after treatment was negatively correlated with the course of disease (<0.05), ie, the longer the disease course of the eyes, the worse the visual acuity and the worse the effect.

CONCLUSIONAcupuncture comprehensive treatment can effectively treat macular edema, significantly improve the patient's vision, improve the subjective experience and the quality of life, and the shorter the course of the disease the more significant effect. Acupuncture comprehensive treatment is better than intramuscular injection of ranibizumab.
