  • Quality Evaluation of Randomized Controlled Trials Involving Traditional Chinese Medicine for Cholelithiasis

    Objective To evaluate the methodological and reporting quality of randomized controlled trials involving traditional Chinese medicine in the treatment of cholelithiasis. Methods We searched CNKI (1994 to 2007), CMCC (1994 to 2007), VIP (1989 to 2007), MEDLINE (1966 to April 2007) and The Cochrane Library (Issue 4, 2006). Data from randomized controlled trials (RCTs) and quasi-RCTs were extracted by two reviewers independently. The methodological quality of included trials was assessed by using the quality assessment criteria recommended by The Cochrane Collaboration, and the reporting quality was assessed by using the CONSORT for TCM checklist. Results Seventeen studies including 16 RCTs and one quasi-RCT were included. The methodological and reporting qualities of included studies were generally low. All studies were graded C. The highest score evaluated by the CONSORT for TCM checklist was 18. Conclusion The quality of RCTs and quasi-RCTs involving traditional Chinese medicine for cholelithiasis is generally low, with a high risk of biases. The reporting of these trials is also incomplete, which would affect a reader’s understanding and evaluation of the validity, importance and applicability of the study results. Therefore, new randomized controlled trials of high quality are required to provide reliable evidence.

  • Effect and Safety of Yinzhihuang Injection for Icteric Viral Hepatitis: A Systematic Review

    Objective To evaluate the effect and safety of Yinzhihuang injection for icteric viral hepatitis. Methods We searched MEDLINE (1966 to 2005), The Cochrane Library (Issue1, 2005), CBMdisk (1978 to 2004), CMCC (1994 to 2005), CMAC (1994 to 2005), CNKI (1994 to 2005), VIP (1989 to 2004). Data were extracted by two reviewers using a designed extraction form. The quality of included trials was critically assessed. RevMan 4.2.7 was used for data analysis. Results Four randomized controlled trials were included. It showed that Yinzhihuang injection could abate jaundice better than or the same as controlled western medicine in patients with hepatitis (WMD 19.70, 95%CI 32.69 to 6.71 and WMD 1.27, 95%CI 3.08 to 0.54, respectively), but less than S-adeanosyl methionine in patients with chronic hepatitis (WMD 106.00, 95%CI 189.05 to 22.95). There may be a dose-effect relationship in Yinzhihuang injection, higher doses had better effect (WMD 11.50, 95%CI 16.53 to 6.47). No fatal side effects were reported.Conclusions It is noted that Yinzhihuang injection can abate jaundice of icteric viral hepatitis. Due to low statistical power and high risk of selection bias, performance bias and measurement bias of the included trials, these conclusions need to be treated cautiously.

  • New type of sutured titanium wire combined with titanium nail internal fixation for correction of serious old medial canthus deformity

    ObjectiveTo evaluate the effectiveness of a new type of sutured titanium wire combined with titanium nail internal fixation in correction of serious old medial canthus deformity.MethodsBetween March 2012 and June 2015, 18 patients with unilateral serious old medial canthus deformity were treated. There were 14 males and 4 females. The patient’s age ranged from 23 to 62 years (mean, 42 years). The causes of deformity included accident injury in 10 cases, boxing injury in 4 cases, sharp device scratching in 3 cases, and animal bite in 1 case. All patients had been treated with suture or steel wire fixation in other hospitals to correct the medial canthus deformity and the deformity recurred. The interval between this operation and the first operation was 6 months to 2 years (mean, 16 months). The nasal root or medial canthus skin scar incision was used as the operative approach, and the adhesion of the medial canthus ligament to the adjacent tissues was fully loosened, then the tail end of the new type sutured titanium wire was fixed to the residual end of the medial canthus ligament. After passing through the scar tissue, the needle end of wire was fixed on the titanium nail in the bone wall of anterior lacrimal crest. The position and shape of the medial canthus angle was determined by adjusting the tightness of titanium wire.ResultsAll incisions healed by first intention. All patients were followed up 6-12 months (mean, 10 months). In 16 cases, the medial canthus deformity was obviously corrected, and the appearances of bilateral eyes were basically symmetrical, without exposure of titanium nail and titanium wire. The medial canthus was retreated at 2 mm after 6 months in 2 cases, who were satisfied with their appearance without reoperation.ConclusionApplication of the new type of suture titanium wire combined with titanium nail in the correction of serious old medial canthus deformity can achieve good effectiveness with the low recurrence rate.

  • Research progress on the relationship between shoulder instability and superior labrum anterior posterior lesion

    ObjectiveTo summarize the relationship between shoulder instability and superior labrum anterior posterior (SLAP) lesion. MethodsThe characteristics of shoulder instability and SLAP lesion were analyzed, and the relationship between them in pathogenesis, clinical symptoms, and biomechanics was discussed by referring to relevant domestic and foreign literature. ResultsShoulder instability and SLAP lesion can occur both spontaneously and respectively. SLAP lesion destroys the superior labrum integrity and the long head of biceps tendon (LHBT) insertion, causing excessive humeral head displacement against glenoid, and leading to shoulder instability. While chronic repetitive or acute high-energy traumatic shoulder instability can in turn aggravate SLAP lesion, resulting in expansion and increased degree of the original lesion. Conclusion SLAP lesion destroys mechanisms of shoulder stability, while shoulder instability causes tears of the upper labrum and the LHBT, showing a connection between shoulder instability and SLAP lesion. However, the existing evidence can only demonstrate that shoulder instability and SLAP lesion induce and promote the development of each other, instead of a necessary and sufficient condition. Therefore, the specific causal relationship between the two remains unknown and needs to be further studied.

    Objective To evaluate the effectiveness and safety of indocyanine green fluorescence method versus modified inflation-deflation method for thoracoscopic anatomic segmentectomy. Methods CNKI, Wanfang Database, China Biomedical Literature Database, Web of Science, Cochrane Library, EMbase, PubMed, Clinicaltrials.gov, were searched from 1 January 2000 to 1 May 2023, and controlled studies between indocyanine green fluorescence and modified inflation deflation method in thoracoscopic segmentectomy were collected. Meta-analysis was performed using Stata14MP and RevMan5.4. Results A total of 10 articles, including 1 156 patients, were identified. In thoracoscopic anatomic segmentectomy, indocyanine green fluorescence method had an advantage over modified inflation deflation method. The total incidence of postoperative complications decreased (OR=0.51, 95%CI 0.36 to 0.71, P<0.0001). The incidence of air leaks decreased (OR=0.50, 95%CI 0.31 to 0.80, P=0.004), the operation time shortened (MD=−25.81, 95%CI −29.78 to −21.84, P<0.00001), the length of postoperative hospital stays shortened (MD=−0.98, 95%CI −1.57 to −0.39, P=0.001), the rate of clear displaying for intersegmental boundary line increased (OR=5.79, 95%CI 2.76 to 12.15, P<0.00001). The difference was statistically significant. Conclusion Compared with modified inflation deflation method, indocyanine green fluorescence method can quickly and clearly display the intersegmental boundary line, reduce the difficulty of surgery, shorten the operation time, reduce the length of postoperative hospital stay, and provide reliably technical support for thoracoscopic anatomic segmentectomy. It is an effective and safe method, which is worthy of extensive application.

  • Preoperative assessment and surgical strategy of intractable epilepsy: report of 125 cases

    ObjectivesTo explore the preoperative assessment method, operative approach and post-operative effect of intractable epilepsy.MethodsOne hundred and twenty five intractable epilepsy patients (85 males and 40 females) from Wuhan Brain Hospital during June 2009 to June 2017 were collected in this study. Their age ranged from 1 to 70 years old, with disease course of 1 ~ 32 years. All the patients underwent VEEG monitoring and MRI examination before operation, and MRS was performed when necessary. Some patients also received psychological assessment. According to the result of VEEG and MRI results, all the patients underwent operations under ECoG monitoring . The surgery effect was followed-up for more than 1 year.ResultsThe post-operative follow-up showed that satisfactory result was achieved in 50 cases, remarkable improvement in 29 cases, good effect in 23 cases, bad effect in 19 cases, and no improvement in 4 cases. The total effective rate of epilepsy surgery was 81.6%, and excellent rate was 41.6%. The effective rate was 81.3% in 80 cases of epileptogenic focus epileptic lesion resection, 87.5% in 40 cases of anterior temporal lobectomy (ATL), and 100% in 3 cases of functional hemispherectomy was, and good effect in the cases of pure cortical coagulation and VNS.ConclusionsThe surgical effects of ATL, epileptogenic focus resection and functional hemispherectomy are better than that of pure corpus callosotomy, multiple subpial transaction (MST), multiple subdural transversely fibrinectomy, VNS or cortical coagulation. So epileptogenic focus should be accurately located preoperatively, and it is better to choose resection operation in order to increase the surgical effect of intractable epilepsy.
