Objective: To evaluate the effectiveness of therapeutic massage (tuina) for treating knee osteoarthritis (KOA). Methods: Six English and Chinese databases, including Chinese National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP), China Biology Medicine Disc (CBM), Cochrane Library and PubMed databases, were independently searched to identify appropriate randomized controlled trials (RCTs) studying therapeutic massage for KOA compared to oral non-steroidal anti-inflammatory drugs (NSAIDs) alone. The main outcome measures were total effectiveness and the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) score. Results: A total of 8 RCTs were included and they were of average quality. The results showed that therapeutic massage was more effective than NSAIDs comparing total effectiveness [risk ratio (RR)=1.14, 95％ confidence interval (CI) (1.07, 1.21), P<0.0001]; compared with NSAIDs, therapeutic massage produced more significant improvements in pain [mean difference (MD)=-2.06, 95％CI (-2.75, -1.36), P<0.00001], stiffness intensity [MD=-0.90, 95％CI (-1.05, -0.75), P<0.00001] and joint function [MD=-12.48, 95％CI (-13.91, -11.05), P<0.00001]. Conclusion: Therapeutic massage was more effective than oral NSAIDs in treating KOA. In relieving pain and stiffness and improving the function of knee joint, therapeutic massage was superior to NSAIDs.

OBJECTIVETo investigate the hazards of aluminum dusts to the exposed workers and the clinical features of aluminosis.

METHODRetrospective investigation on 75 aluminosis patients from a certain factory diagnosed in Shanghai Occupational Diseases Hospital from 1972 to 2004 was carried out.

RESULTSThere were 27 cases of aluminosis I (36.0%), 28 cases of aluminosis II (37.3%) and 20 cases of aluminosis III (26.7%) among 75 cases. The shortest exposure duration was 3 years, and the longest 17 years, and 37 cases of aluminosis occurred after exposure less than 10 years. hest radiographic examination mainly showed irregular micro-shadows: t (22/75), s (4/75), t/u (1/75), t/s (2/75), or predominantly irregular mixed microshadows s/p (5/75), s/r (1/75), t/p (9/75), t/q (5/75); some showed round shape micro-shadows: p (6/75), q (1/75), p/q (3/75), q/p (1/75). 27 cases showed large shadows, 20 cases of them were diagnosed as pneumoconiosis III. A lot of irregular micro-shadows gathered and developed to form uneven, loose and border-irregular masses. Most massive fibrosis looked like stripe or plait, located mostly in middle and upper lung field. 8 patients suffered from aluminosis with single side of massive fibrosis and 12 with both sides of massive fibrosis, accounting for 40% and 60% respectively. Mediastinal and bronchopulmonary lymph nodes were enlarged and calcified, accompanied with pleural thickening.

CONCLUSIONSShort exposure to high concentration of black fused alumina may cause serious aluminosis to the exposes. The hazards of aluminum dusts should not be ignored.

·AIM: To analyze the clinical efficacy and safety of vitrectomy combined with cyclophotocoagulation in the treatment of traumatic glaucoma, and to provide an effective treatment for improving the quality of life of patients with traumatic glaucoma. ·METHODS:Totally 90 patients (90 eyes) with traumatic glaucoma admitted in our hospital from January 2011 to July 2016 were divided into two groups (45 patients in each group) according to different treatment methods. The patients in the observation group underwent vitrectomy combined with cyclophotocoagulation under direct vision; the control group underwent vitrectomy combined with trans-scleral cyclophotocoagulation. We observed the effect of different treatment on visual acuity, intraocular pressure and complication of the two groups. ·RESULTS: The visual acuity of the observation group was significantly better than that of the control group after treatment (Z=-5.689, P<0.05). There was no significant difference on intraocular pressure between the two groups before treatment (P>0. 05). The change of decreased intraocular pressure in the observation group was less than that in the contral group after operation (P<0.05). After 1a follow-up,there was no significant difference on the change of decreased intraocular pressure between the two groups (P>0. 05). The complications of the two groups after treatment were vitreous hemorrhage, choroidal detachment, low intraocular pressure, increased intraocular pressure and other complications, but the complication rate of two groups were no different (x2=1.553,P=0.213).· CONCLUSION: Vitrectomycombinedwith cyclophotocoagulation under direct vision brings patients better visual acuity than that combined with trans-scleral cyclophotocoagulation.

Objective To explore the effect of intervertebral foramen puncture under image equipment guidance. Methods 52 patients with lumbar disc herniation from January 2014 to January 2017 were enrolled in this study. All the patients underwent lumbar posterior lateral approach for endoscopic surgery. Patients were divided into control group and observation group by random number table method, 26 patients in each group. The patients in the observation group were treated with ultrasound volume, and the patients in the control group were treated with C arm X-ray machine. The intraoperative condition, preoperative and postoperative visual analogue scale (VAS score), Oswestry dysfunction index (ODI score) and postoperative complications were compared between the two groups. Results The operation time, the total time of puncture and the number of fluoroscopy were lower in the observation group than that in the control group. The patients in the observation group and the control group were treated before operation, 1 month after operation, 3 months after operation, 6 months after operation and there was no statistically significant difference in VAS score and ODI score between 12 months (P > 0.05). The patients in the observation group and the control group had no significant complication after operation. Although they had pain symptoms, they could be relieved by themselves or by drug treatment. Conclusion Ultrasonic volume navigation can enhance the accuracy of puncture and reduce the puncture time, and there is no significant complication after operation. The safety is better than that of C arm X-ray machine.
