Objective: To investigate the incidence and survival rates of primary RCC (renal cell carcinoma) in residents in Pudong New Area in Shanghai. Methods: The residents in Pudong New Area in Shanghai were recruited in this study during the period 2002-2011. The standardized morbidity and mortality of primary RCC were calculated by world standard population. The survival of primary RCC patients according to gender, resident district, TNM staging and surgical operation was analyzed by Kaplan-Meier method and COX regression analysis. Results: Among 1 905 new cases of primary RCC occurring during 2002-2011, 1 234 were males and 671 were females. The age-standardized incidence rate in males (5.17/100 000 person-year) was higher than that in females (3.07/100 000 person-year). In 697 cases of RCC-related death, 453 were males and 244 were females. The age-standardized mortality in males (1.88/100 000 person-year) was higher than that in females (0.92/100 000 person-year). The one-, two-, three-, four-, and five-year survival rates of patients with primary RCC were 74.75%, 69.84%, 66.38%, 63.40% and 61.44%, respectively. There was a statistically significant difference in overall survival between central city vs other areas (P = 0.040), early stage vs advanced stage (P < 0.001), and having surgical operation vs not having surgical operation (P < 0.001). Advanced stage and not having surgical operation were independent risk factors in patients with primary RCC (P < 0.001). Conclusion: The incidence and mortality rates of primary RCC in males and in central city were significantly higher than those in females and in other areas in residents in Pudong New Area in Shanghai, 2002-2011, respectively. Early diagnosis of primary RCC and performance of surgery can significantly improve the prognosis of patients. Copyright © 2013 by TUMOR.

Objective: To observe the effect of muscle regions of meridians warm needling method plus pricking Jing-Well points for blood-letting in improving nail fold microcirculation in the patients with shoulder-hand syndrome (SHS) after stroke, and the effects on hemorrheology, calcitonin gene-related peptide (CGRP) and serum substance P (SP). Methods: A total of 72 patients were randomized into an observation group and a control group by the random number table method, with 36 cases in each group. The control group was treated with physical rehabilitation training, and the observation group was treated with additional muscle regions of meridians warm needling method plus pricking Jing-Well points for blood-letting treatment. The treatment course lasted for 4 weeks. After treatment, the clinical efficacy of the two groups was compared. The changes in shoulder-hand syndrome scale (SHSS), simplified Fugl-Meyer assessment-upper extremity (FMA-UE), visual analog scale (VAS), activities of daily living (ADL), traditional Chinese medicine (TCM) syndrome score, nail fold microcirculation hemorheology indictors [whole blood viscosity (high-shear, low-shear), hematocrit, erythrocyte sedimentation rate (ESR)], CGRP and SP levels were observed. Results: The total effective rate in the observation group was 86.1％, higher than 63.9％ in the control group (P<0.05). The overall curative effect in the observation group was better than that in the control group (P<0.05). After treatment, the scores of pain sensation, edema, external turn and rotation of the arm in SHSS, and the total score were significantly decreased in both groups (all P<0.05), and each score in the observation group was lower than that in the control group (all P<0.05). After treatment, the scores of VAS and TCM syndrome in both groups decreased significantly (all P<0.05), and the scores of FMA-UE and ADL increased significantly (all P<0.05). The scores of VAS and TCM syndrome in the observation group were lower than those in the control group (both P<0.05), and the scores of FMA-UE and ADL were higher than those in the control group (both P<0.05). After treatment, the whole blood viscosity (high-shear and low-shear) and hematocrit in both groups decreased obviously (all P<0.05), and ESR increased obviously (both P<0.05), and the whole blood viscosity (high-shear and low-shear) and hematocrit in the observation group were lower than those in the control group (all P<0.05), and ESR was higher than that in the control group (P<0.05). After treatment, the peritubular state, loop shape, blood flow and total score of nail fold microcirculation in both groups decreased significantly (all P<0.05), and each score in the observation group was lower than that in the control group (all P<0.05). After treatment, SP in both groups decreased obviously (both P<0.05), CGRP increased obviously (both P<0.05), and SP in the observation group was lower than that in the control group (P<0.05), CGRP was higher than that in the control group (P<0.05). Conclusion: Compared with conventional physical rehabilitation training, muscle regions of meridians warm needling method plus pricking Jing-Well points for blood-letting treatment can significantly reduce the clinical symptoms of SHS, promote the recovery of physical functions, improve the nail fold microcirculation and hemorrheology indictors, and regulate the serum cytokine levels such as CGRP and SP.

Objective To determine the medium-long term functional outcome of arthroscopic repair of type II SLAP lesions with two loops.Methods According to retrospective study,29 cases patients with arthroscopic repairs of isolated type II SLAP lesions were collected from March 2011 to June 2013,the mean patient age at the time of surgery was 31.8 years(range17 to 47 years).All patients with ground anchor suture,and through double loop knot technology to fix SLAP injury.Visual analogue scale(VAS),Kerlan-Jobe Orthopaedic Clinic(KJOC),Roche Shouder function Score(ROWE) were used to determine the function of shoulder joint.The shoulderjoint range of motion before treatment and post treatment were recorded,shoulder joint mobility was recorded,satisfaction survey was done,compared the preoperative and postoperative data to evaluate its clinical effect.Results All patients were available for follow-up of 2.7-5.2 years.Overall,functional outcome was improved from baseline compared with final follow-up for VAS scores((4.3±1.2) points vs.(1.5±0.8) points,t=5.435,P<0.05),KJOC scores((72.1±4.9) points vs.(92.8±5.4) points,t=5.921,P<0.01),and ROWE scores((54.1±12.4) points vs.(84.3±10.2) points,t=7.326,P<0.01).Only a minority of patients feel pain when they did srenuous exercise.According to satisfaction investigation of patients,patient satisfaction was reported in 89.7%,3 cases had not good results,they could not return to previous level of play,including 2 cases were athletes,1 case was not athlete.Conclusion There is no more persistent pain and dysfunction after surgery,a good or excellent medium-long term functional outcome can be anticipated after arthroscopic repair of type II SLAP lesions with two loops.

Objective To investigate the transcription and expression of DNA methyltransferase 1 (DNMT1) mRNA in endemic arsenism patients by burning coal usage,to probe its effects on the development and carcinogenesis of arsenism. Methods In 2008,68 arsenism patients(including 24 mild cases,28 moderate cases and 16 severe cases) were selected in the areas with endemic arsenism according to Standarding of Diagnosis for Endemic Arsenism from Xingren county,Guizhou province. Among the subjects,40 cases were diagnosed by pathological methods,and they were divided into general pathological changes(20),precancerous(14) and cancerous group(6). Tweleve kilometer away from the endemic arsenism area,23 controls were selected in Daguoduo village (non-arsenism exposure). Under the principle of informed consent,blood samples were collected from individuals. The mRNA expression of DNMTI was detected by real-time quantitative reverse transcription polymerase chain reaction(FQ-PCR). At the same time,skin tissue samples were collected from the voluntary surgical treatment patients with endemic arsenism (total 61 cases,including 34 general pathological changes cases,21 precancerous cases and 6 cancerous cases) and from the control(15 cases). DNMT1 protein was detected by immunohistochemical method.Results Average level of DNMT1 mRNA were 0.221 83±0.595 09,0.246 11±0.509 79 and 0.389 27±0.411 33 respectively among mild,moderate and severe arsenism group. DNMT1 mRNA level of mild and moderate group were obviously lower than the control group(0.695 95±0.463 98,all P < 0.01). The mRNA average level of DNMT1 were 0.320 64±0.547 46,0.313 09±0.529 13 and 0.159 07±0.342 56 individually among general pathological changes,precancerous and cancerous group,which were obviously lower than the control group(0.695 95±0.463 98,all P < 0.05). The expression rates of DNMT1 protein in skin were 88.24%(30/34),100%(21/21) and 100% (6/6) among general pathological changes,precancerous and cancerous group were higher than the control group [0(0/15),all P < 0.01],and the extent of expression gradually increased with the aggravation of skin damage(r,= 0.740,P < 0.01). Conclusions DNMT1 participated in the development of the arsenism. High expression of its protein was an early event during the process of the arsenism. DNMT1 may be the new target markers for early diagnosis and treatment of arsenism.
