Objective: To observe the differential expression of epithelial membrane antigen (EMA) and renal cell carcinoma marker (RCC-Ma) in early renal carcinoma and corresponding adjacent (0.5, 1.0, and 2.0 cm) tissues, so as to estimate the safe margin of laparoscopic partial nephrectomy for renal tumors. Methods: Tissue microarrys, including 44 tissues of clear cell renal cell carcinoma[A] and normal renal cortex tissues of different distances to the tumor: 0.5 cm[B], 1.0 cm[C] and 2.0 cm [D], were constructed. The expression of EMA and RCC-Ma was examined by immunohistochemical staining in the four groups. Results: Intensive membranous and (or) cytoplasmic staining of EMA and RCC-Ma was observed in the cancer and adjacent tissues. The positive rate in group A was significantly higher than those of the other three groups (A [15.91%/ 18.18%], B[84.09%/79.55%], C[86.36%/77.27%] and D[79.55%/75.00%], P<0.01). The positive rates of EMA and RCC-Ma expression were not significantly different between the group B, C, and D(P>0.05). Conclusion: Our data denote that, when laparoscopic partial nephrectomy is done for early renal carcinoma, at least 5 mm of normal parenchyma tissue beyond the pesudocapsule should be excised with the tumor.

Objective To compare the efficacy of uniportal VATS and single utility port VATS in treatment of spontaneous pneumothorax.Method From January 2013 to December 2015, we retrospectively collected clinical data of 53 patients with spontaneous pneumothorax who were treated with uniportal VATS, as study group; compared with control group: 53 patients received single utility port VATS in the same period. The clinical data was compared between the two groups, including the operation time, intraoperative blood loss, drainage time, postoperative extubation time, postoperative pain score, postoperative hospitalization and recurrence.Results All patients were successfully completed the operation, no death and serious complications occurred. There were no significant differences in intraoperative blood lose, duration of chest drainage, duration of hospital stay and incidence of serious postoperative complications between two groups (P > 0.05). Mean Visual Analogic Scale (VAS) score for 24 h post-operative pain was: (2.60 ± 0.71) for uniportal VATS and (3.38 ± 0.84) for single utility port VATS (P > 0.05), 72 h post-operative pain was: (1.30 ± 0.51) for uniportal VATS and (1.58 ± 0.62) for single utility port VATS (P > 0.05). Follow up 5 ~ 36 months, median follow up was 19 months. No recurrence occurred during follow up.Conclusions The study suggested that both surgical approaches to spontaneous pneumothorax are safe and effective. Significant differences were found for early post-operative pain between the two approaches, the uniportal way is better. It is worthy of clinical promoting.

Objective To observe the clinical efficacy of acupuncture plus medicine and function training in treating post-stroke shoulder-hand syndrome. Method Sixty patients with post-stroke shoulder-hand syndrome were randomized into a treatment group of 30 cases and a control group of 30 cases. The treatment group was intervened by acupuncture plus medicine and functional training, while the control group was only by functional training. Before and after intervention, the hand swelling degree, Visual Analogue Scale (VAS), shoulder joint motion scale, Fugl-Meyer Assessment (FMA) scale were used to measure the swelling and pain of hand, motion of shoulder, and motor function of upper limb. Result After intervention, the swelling and pain of hand, motion range of shoulder and motor function of upper limb were significantly improved in both groups (P<0.01), and the improvements in the treatment group were more significant than that in the control group (P<0.05). Conclusion Acupuncture plus medicine and function training can enhance the efficacy in treating post-stroke shoulder-hand syndrome, superior to pure function training.

OBJECTIVETo compare therapeutic effects between arthroscopic medial retinaculum plication and plaster external fixation for the treatment of acute patellar dislocation.

METHODSFrom February 2006 to October 2012,29 patients with acute patellar dislocation were divided into two groups: operation group and non-operation group. The patellar dislocation duration was 2 weeks. In operation group, there were 7 males and 10 females, with an average age of (16.2 ± 6.2) years old, and the patients were treated with arthroscopic medial retinaculum plication. In non-operation group, there were 5 males and 7 females,with an average age of (16.3 ± 5.0) years old,and the patients were treated with plaster external fixation. The Kujala scores, patellar tilt angle measured on CT film, apprehension test and recurrence rate of patellar instability were observed before and 1 year after treatment.

RESULTSIn operation group, the pre-treatment and post-treatment patellar tilt angles had no statistical difference, but the post-treatment Kujala score was lower than that of pre-treatment; while in non-operation group, the post-treatment patellar tilt angle was larger than that of pre-treatment, and the post-treatment Kujala score was lower than that of pre-treatment. At 1 year after treatment, the patellar tilt angle (21.2 ± 5.3) of patients in non-operation group was larger than (13.5 ± 3.5) of operation group, and the Kujala score 73.3 ± 10.5 of patient in non-operation group was lower than 84.1 ± 5.6 of operation group.

CONCLUSIONDuring 1 year after operation, arthroscopic medical retinaculum plication is a more effective treatment for acute patellar dislocation compared with plaster external fixation.

Objective To investigate the diagnostic value of MRI in the infantile developmental dislocation of the hip.Methods Forty-five cases of preoperative hip MRI data of DDH (patient group)and 40 cases of normal hip (control group)MRI data were retrospectively analyzed.Three types were classified according to the standard of Dunn.Then the bony acetabular index (BAI),cartilaginous acetabular index (CAI)were measured on coronal MRI and all the intra-articular structures (articular cartilage,labrum, teres ligament and iliopsoas)in the acetabulum that impeded the reduction of the femoral head were observed.Results There were normal hips (80 hips)and dislocated hips (73 hips).In dislocated hips typeⅠ (30 hips),typeⅡ (20 hips),and typeⅢ (23 hips) were found.The values of BAI were (26.13±2.19)°and (35.87±4.42)°,CAI (13.84±1.07)°and (21.92±4.70)°for patient group and control group.The values of BAI were (31.80±1.74)°,(37.80±3.40)°and (39.17±4.11)°,CAI (17.20±2.68)°,(20.91±2.02)°and (27.50±2.78)°for the typesⅠ,Ⅱ,Ⅲ respectively.Differences of BAI and CAI between patient group and control group were showed (t=-11.048 and -9.188,P =0.000).Statistically significants were found among the typeⅠ,Ⅱ,Ⅲ(F=22.159 and 47.241,P =0.000).There were linear correlations for patient group ,control group,and the typeⅠ,Ⅱ,Ⅲ (r= 0.964,0.844,0.953,0.931 and 0.870,P =0.000).Some pathological changes such as varus labrum,thick teres ligament,iliopsoas spasm,articular cartilage hyperplasia,fat hyperplasia,joint effusion were observed in the type Ⅱand Ⅲ.Conclusion MRI is not only used for measuring the values of BAI and CAI,and a linear correlation among all kinds of DDH,but also some factors hindering the reduction of the femoral head can be found clearly.It can provide an important reference basis for the diagnosis and treatment of DDH.

OBJECTIVETo observe the effect of staged Chinese herbal medicinal therapy combined with chemotherapy in treating patients with non-small-cell lung cancer (NSCLC) of stage III or IV.

METHODSAdopting prospective randomized controlled multi-centered method, the 116 patients enrolled were assigned to the treated group (n = 60) and the control group (n = 56). The control group was treated by chemotherapy alone, while the treated group treated by chemotherapy combined with Chinese herbal medicine, i.e. Kangliu Zengxiao Decoction (KLZX) was administered in the chemotherapy stage, followed with Feiyanning Decoction (FYN) in the stage after ending the chemotherapy. The survival time, Karnofsky score, main clinical symptoms and adverse reactions, etc. were observed.

RESULTSThe median survival time was 15.57 months in the treated group, which was higher than that in the control group (11.17 months, P< 0.01). The improvements in tumor related symptoms such as fatigue, dyspnea, etc. in the treated group were better than those in the control group (P <0.05). In addition, adverse reactions such as leucopenia, digestive reaction (such as nausea and vomiting) in the treated group were less than those in the control group (P <0.05).

CONCLUSIONChinese herbal medicine combined with chemotherapy shows favorable effect in improving quality of life and prolonging survival time on patients with advanced NSCLC.

OBJECTIVETo investigate the effect of oridonin on the human acute lymphocytic leukemia cell line Jurkat and its mechanism.

METHODSJurkat cells were cultured in vitro and treated with various concentrations (0, 1.25, 2.5, 5, and 10 μmol/L) of oridonin for different lengths of time (24, 48, and 72 hours). The proliferation of Jurkat cells was analyzed by MTT assay. The changes in nuclear morphology were evaluated by fluorescence microscopy at 12 hours after treatment with various concentrations of oridonin. The expression levels of Brg1, P53, and C-myc were determined by semi-quantitative Western blot in Jurkat cells treated with various concentrations of oridonin for 24 hours or 5 μmol/L oridonin for various lengths of time (0, 2, 6, 12, and 24 hours). The expression levels of P53 and C-myc and proliferation of Jurkat cells were evaluated after Brg1 expression was knocked down by Brg1-specific siRNA.

RESULTSCompared with the control group, the proliferation of oridonin-treated Jurkat cells was significantly inhibited in a concentration- and time-dependent manner (P<0.05). According to the florescence microscopic analysis, oridonin treatment led to nuclear pyknosis in Jurkat cells. Compared with the control group, Jurkat cells treated with 5 μmol/L oridonin had reduced expression of Brg1 and C-myc but elevated expression of P53. Brg1 knock-down led to a significant reduction in proliferation of Jurkat cells (P<0.05), up-regulated expression of P53, and down-regulated expression of C-myc.

CONCLUSIONSOridonin can inhibit the proliferation of Jurkat cells, probably via the Brg1 signaling pathway.
