Objective To investigate the effect of recurrent patella dislocation by grafting dual-bundle semitendinosus to anatomically reconstruct of medial patellofemoral ligament(MPFL)under arthroscopy.Methods From January 2006 to January 2010,29 cases(31 knees)with recurrent dislocation of the patella were performed arthroscopic surgery,including 11 males and 18 females(20 knees)with an average age of 22 years(range,16-32).The key point of surgery was reconstruction MPFL with dual-bundle free autogenous semitendinosus by using two anchors and bone groove to fixed on the patella,and using the interference screw to fixed on the femur.Adjusting the patella reset under arthroscopy.Tibial tubercle were transferred to inside in 5 cases.All patients were followed up for an average of 14 months(ranging 9-22).The imaging evaluation included congruence angle,lateral patellofemoral angle and lateral shift.The clinical therapeutic effect was evaluated with International Knee Documentation Committee(IKDC),Lysholm and Tegner scores.Results The fear test was negative after operation.There was no redislocation and fracture of the patella during follow-up.The congruence angle,lateral patellofemoral angle and lateral shift were 5.65°±2.23°,3.52°±2.63° and 0.25±0.46 respectively at the final follow-up.The mean IKDC,Lysholm and Tegner scores were 93.20±5.33,93.02±6.08 and 6.58±0.87 respectively at the final follow-up.All were showed statistically significant differences compared with preoperation(P＜0.05).Conclusion It is demonstrated that there was a reliable short-term effect to treat recurrent patella dislocation by grafting dual-bundle semitendinosus to anatomically reconstruct of MPFL under arthroscopy.

Objective To explore the causes of postoperative recurrence in patients of nodular goiter,the selection of method for reoperation and the postoperative complications. Methods The clinical data of 278 nodular goiter patients admitted in the first affiliated hospital of Harbin Medical University between 2001 and 2008 were analyzed retrospectively,including the methods and complications for first operation and reoperation. Results In the first operation,79 eases received simple eminectomy and 167 cases received partial lobectomy,accounted for 28.4% and 60.1%,respectively. Unilateral subtotal lobectomy plus contralateral eminectomy was performed in 23 cases and subtotal thyroideetomy was conducted in 9 cases,accounted for 8.3% and 3.2%,respectively. Postoperative complications occurred in one hundred and twenty-three cases,the incidence being 8.2% (23/278). Unilateral subtotal Iobectomy plus contralateral partial iobectomy was reperformed in 37 cases and bilateral subtotal thyroidectomy in 241 cases. Postoperative complications occurred in 12 cases,the incidence being 4.2%(12/278). No postoperative recurrence of nodular goiter was found. Conclusions Recurrence of nodular goiter is closely associated with the scope of previous surgical treatment,and correct operative manipulation may reduce the recurrent rate.

BACKGROUND: An antibiotic-free, fixed-dose combination gel with adapalene (A) 0.1% and benzoyl peroxide (BPO) 2.5% has been developed for treatment of acne vulgaris. OBJECTIVE: To compare the clinical outcomes of A-BPO combination gel with vehicle gel for treatment or maintenance therapy of patients with acne vulgaris. METHODS: An electronic search of the database PubMed (1966 to September 2012), Embase (1984 to September 2012), and Cochrane Controlled Trials Register (CENTRAL; 3rd Quarter, 2012) was undertaken to identify relevant studies. Main clinical outcomes were success rate, treatment-related adverse events (AEs), AEs leading to discontinuation, satisfaction with the effectiveness, and overall satisfaction. RESULTS: Six studies were finally included in this meta-analysis. The A-BPO group yielded better clinical outcomes regarding the success rate (p<0.00001), satisfaction with the effectiveness of treatment (p=0.005), and overall satisfaction (p=0.005) compared to the vehicle group. The incidence of treatment-related AEs in the A-BPO group was comparable with that of vehicle group (p=0.09), while the A-BPO group was associated with a slightly increase in the incidence of AEs leading to discontinuation when compared with the vehicle group (p=0.02). CONCLUSION: A-BPO combination gel yields better clinical outcomes including success rate, satisfaction with the effectiveness, and overall satisfaction compared to vehicle gel, despite an increased incidence of AEs leading to discontinuation. The A-BPO combination agent most likely contributes to the treatment of moderate acne vulgaris rather than severe acne vulgaris, but it may be useful in maintenance therapy of patients with severe acne vulgaris.

Objective To investigate the effect of Candida albicans and its components on the expression level of human beta-defensin-2 mRNA (HBD-2) in keratinocytes in vitro. Methods Different components of Candida albicans were isolated by lyticase, repeated freezing and thawing, sonication, and centrifugation. The keratinocytes and HaCaT cell lines were co-cultured with Candida albicans and its cellular components for 24 h. The expression level of HBD-2 mRNA was detected by reverse-transcription polymerase chain reaction (RT-PCR). Results Low expression level of HBD-2 mRNA in the unstimulated keratinocytes and HaCaT cells was detected. The HBD-2 mRNA expression levels in the keratinocytes stimulated by Candida albicans, the extract of its cell wall, and pure mannan were significantly increased (P 0.05). Conclusions Candida albicans, the extract of cell wall of Candida albicans, and commercial mannan can increase the expression level of HBD-2 mRNA in keratinocytes.

OBJECTIVETo investigate the mechanism of Tougu Xiaotong Granula (TXG) on prevention and treatment of knee osteoarthritis.

METHODSFifty New Zealand rabbits were randomly divided into 6 groups. Except those in the normal control group, all the rabbits were replicated into knee osteoarthritis model using modified Hulth method. They were administered by gastrogavage once every day respectively with 100 ml of normal saline to the rabbits in the normal group and those in the model group, with 10 g of Zhuanggu Guanjie Pill to those in the control group, and 5 g, 10 g and 20 g of TXG to those in the three TXG tested groups (tested group 1, 2 and 3). The levels of interleukin-1 (IL-1), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha) and metalloproteinase 3 (MMP-3) in joint fluid, the blood content of malondialdehyde (MDA) and nitric oxide (NO) absorbance as well as the SOD activity in synovia were observed.

RESULTSOverexpressions of IL-1, IL-6, TNF-alpha and MMP-3 in joint fluid, increased blood content of NO and MDA were shown in the 8th and 16th week, and decreased SOD activity in synovia was shown in the 16th week of the experiment in all the model rabbits, as compared to those in the normal group, the difference was significant respectively (P < 0.05 or P<0.01). After 8 weeks of treatment, the levels of IL-1, TNF-alpha, MMP-3, NO and MDA in the control group, tested group 2 and 3 were significantly different to those in the model group respectively (P < 0.05, P < 0.01), and significant difference was also shown in the comparisons of those indexes between the control group and the tested group 1 vs the tested group 3 (P < 0.05). As for the level of IL-6, significant difference was shown in comparisons of the model group with the control group, tested group 2 and 3 in the 8th and 16th week of the treatment (P < 0.05 or P < 0.01), also in comparison of the tested group 3 with the tested group 1 in the 8th week, and in that of the tested group 2 with the control group and the tested group 1 in the 16th week (P < 0.05).

CONCLUSIONTXG could effectively postpone the degeneration of cartilage through effectively inhibiting the biological effects of cytokines, MMP-3 and oxygen free radical.

OBJECTIVETo investigate the diagnoses and treatment of interstitial cystitis (IC).

METHODSThe clinical data of 16 IC patients were analyzed respectively. The patients with urinary frequency, urgency, suprapubic pain and chronic pelvic pain. They were misdiagnosed as chronic cystitis, pelvic inflammation, endometriosis, cystophthisis and urethral syndrome, and were diagnosed finally by the means of pathology or cystoscopy. Among the 16 patients, 4 cases had the operation of ileal reservoir, Two cases had sigmoid-cysto-plasty, and 10 cases had drug treatment. The methods of IC diagnosis and treatment were discussed with the review of literature.

RESULTSThe pelvic ache disappeared completely in 4 cases after the operation of ileal reservoir; Two cases after cystoplasty felt lightly discomfortable in perineum occasionally, and their bladder capacity was above 350 ml, no recurrence after operation having been found after follow-up for 24 months and 33 months; Ten cases treated with non-operative treatment improved obviously, with the O'Leary-Sant IC symptom index and IC problem index decreased from 15.4 +/- 4.1, 9.4 +/- 2.7 to 4.1 +/- 2.1 and 5.1 +/- 3.9, respectively.

CONCLUSIONSSufficient attention should be paid to the diagnosis and differential diagnosis of IC; Early diagnosis and therapeutic alliance with manifold measures can relieve the patients' symptom and improve the quality of life.

Objective To compare the transplant-related toxicity and the efficacy of busulfan/fludarabine (Bu/Flu) and busulfan/cyclophosphamide (Bu/Cy) as conditioning regimen in allogeneic hematopoietic stem cell transplantation (allo-HSCT) for acute myeloid leukemia(AML) in the first complete remission (CR1).Methods Totally 32 AML-CR1 patients underwent allo-HSCT were divided into Bu/Cy (Bu 3.2 mg· kg-1 · d-1,7-4 days before transplantation; Cy 60 mg · kg-1 · d-1,3-2 days before transplantation) and Bu/Flu (Bu 3.2 mg · kg-1 · d-1,5-2 days before transplantation; Flu 30 mg · m-2·d-1,6-2 days before transplantation) groups.The regimen-related toxicity (RRT),incidence and severity of graft-versus-host disease (GVHD),3-year cumulative relapse rate,non-relapse mortality (NRM),3-year event-free survival (EFS) rate and overall survival (OS) rate were compared between the two groups.Results The median follow-up duration was 617.5 (6-1261) days.All patients achieved successful engraftment on 30 day after transplantation.There were no significant differences in the median time to neutrophil engraftment (P =0.121) and platelet engraftment (P =0.171) between the two groups.The median duration of neutrophil count under 0.1 × 109/L and platelet count under 20 × 109/L in the Bu/Cy group were significantly longer than those in the Bu/Flu group (P =0.000 and P =0.047).The incidence of grades Ⅱ-Ⅳ RRT were 68.8％ and 25.0％ (P =0.032) in the Bu/Cy and the Bu/Flu groups,respectively.There were no significant differences in the incidence of acute GVHD (P =0.149),chronic GVHD (P =0.149),incidence of NRM (P =0.333),3-year cumulative relapse rates (P =0.834),3-year EFS rate (P =0.362) and OS rate (P =0.111) between the two groups.Conclusion Compared with Bu/Cy,Bu/Flu is a myeloablative condition regimen with milder bone marrow suppression and lower RRT incidence rate in allogeneic HSCT for AML-CR1 patients without compromising the efficacy.

OBJECTIVETo analyze the influence of intravesical Pirarubicin (THP) instillation on the prediction results of European Organization for Research and Treatment of Cancer (EORTC) risk tables and to discuss the efficacy of EORTC risk tables in clinical application.

METHODSWe retrospectively reviewed the clinical data of 389 patients with non-muscle invasive bladder cancer after TURBT treated with intravesical pirarubicin instillation. According to the EORTC Scoring System, all the cases were divided into low risk group, intermediate risk group and high risk group. The 1-year and 5-year recurrence and progression rates of each group were calculated and compared with the prediction results of the EORTC risk tables.

RESULTSThe 1-year recurrence and progression rates of the low risk group were 8.0% and 0, those of the intermediate risk group were 31.0% and 2.8%, and those of the high risk group were 52.5% and 18.6%, respectively. The 5-year recurrence and progression rates of low risk group were 16.0% and 5.3%, those of the intermediate risk group were 42.6% and 10.7%, and those of the high risk group were 63.9% and 41.9%, respectively. The prediction results of progression rate were similar to that of the EORTC risk tables while the overall recurrence rate was lower.

CONCLUSIONSThe EORTC risk tables can be effectively used to predict the recurrence rate and progression rate of non-muscle invasive bladder cancer. However, the EORTC risk tables have a tendency to overestimate the recurrence rate. Intravesical pirarubicin instillation is helpful to reduce the recurrence rate, yet has no obvious influence on the tumor progression.
