OBJECTIVETo observe clinical effect of integrated Chinese medical (CM) treatment (as maintenance therapy) on the progression-free survival (PFS) and overall survival (OS) in patients with advanced non-small-cell lung cancer (NSCLC) after first-line chemotherapy.

METHODSThe study was a prospective, randomized, controlled clinical trial. Totally 69 non-progressive advanced NSCLC patients treated with first-line chemotherapy were randomly assigned to the test group (34 cases) and the control group (35 cases). Patients in the control group were treated with one Western drug chemotherapy (Gemcitabine or Alimta or docetaxel). Those in the test group were treated with integrated CM treatment (CM decoction, CM Intravenous preparation, and point application). Each cycle consisted of 21 days. Treatment lasted till the disease progressed, or intolerable toxic/adverse reactions occurred, or patients refused to continue the treatment. Patients' life spans were regularly followed-up.

RESULTS(1) The median cycle of maintenance therapy was 2 cycles for two groups with no statistical difference (P =0.274). The median PFS was 12.43 weeks in the test group and 10.00 weeks in the control group, showing statistical difference (P =0.025). The middle survival time (MST) was 18.8 months in the test group and 16.73 months in the control group, showing no statistical difference (P =0.437).

CONCLUSIONCM treatment (as maintenance therapy) showed quail effect to one Western drug chemotherapy in prolonging patients' life span.

Objective To investigate the clinical characteristics of posterior malleolar ankle fracture, and the selection of the surgical approach. Methods From January 2013 to September 2015, 83 cases of posterior malleolar fractures were retrospectively analyzed. Haraguchi typing was performed based on the three-dimensional CT. There were 54 cases with HaraguchiⅠtype, 16 cases with HaraguchiⅡtype, and 13 cases with HaraguchiⅢtype. The patients who were HaraguchiⅠand Haraguchi Ⅲtypes accepted the operation with posterolateral approach. The patients who were HaraguchiⅡtype and combined medial malleolus fracture accepted the operation with medial approach. The HaraguchiⅡpatients who were not combined medial malleolus fracture were used the medial paraachilles approach. Images of the ankle joint were filmed 2 weeks, 4 weeks, 12 weeks, 6 months and 12 months after the surgery. The healing time, complications and corresponding record outcome were determined by X-ray and clinical examination. At the last follow-up, ankle function and quality of life of patients were evaluated according to the American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot score and SF-36. Results Eighty-three patients were follow-up for 6-24 (mean 15.4± 6.2) months. The fractures healed on X-ray. The average X-ray healing time was from 12 to 24 (mean 18.6±4.2) weeks. AOFAS score was 71 to 100 (mean 88.4±8.4) points. Sixty-seven cases were excellent, 14 cases were good, 2 cases were moderate, and good rate was 97.59%. SF-36 physiological score was 31.6-69.2 points(mean 48.4 ± 4.8 points);SF-36 psychological score 28.6-64.5 points(mean 45.8 ± 3.5 points). Chronic ankle pain was complained by one patient. He was diagnosed traumatic arthritis, oral non-steroidal drugs was used to relief his ankle pain. One patient wound infected, and healed after treatment. No instrument failure and fracture displacement were found. Conclusion According to fracture morphology and clinical features after posterior malleolar ankle fracture, different surgical approaches are selected, which will be satisfied with the outcome.

The mRNA levels of adiponectin in adipose tissue and adiponectin receptor R1 in skeletal muscle of type 2 diabetic rats were examined by semi-quatitative RT-PCR.The expression of adiponectin receptor R1 was not altered in the skeletal muscle of type 2 diabetic rats as compared with normal rats.The serum adiponectin level was decreased in diabetic rats due to the decline of adiponectin mRNA level in adipose tissue and rosiglitazone improved the adiponectin deficiency.

Objective To explore genes expression of adiponectin receptors during differentiation of SW872 preadipocytes. Met-(hods) SW872 preadipocytes were cultured in vitro and induced to differentiate by 0.6 mmol/L oleic acid. During the progress of diffe-(rentiation), the morphological changes of SW872 cells were observed and the differentiation rate was assayed by oil-red O staining. Adiponectin receptors mRNA was measured by reverse transcription-polymerase chain reaction during differentiation of SW872 preadipocytes. Results 1.After stimulated by 0.6 mmol/L oleic acid for 72 hours, almost all SW872 cells were differentiated,and there were lots of fat droplets in the cells.2.There were adiponectin receptors genes expressions in SW872 preadipocytes.After 72 hours,and the levels of adiponectin receptor(AdipoR) 1 mRNA and AdipoR 2 mRNA were markedly increased up to 2.54 and 4.09 times,respectively. Conclusion There are AdipoR1 and AdipoR2 genes expressions in fat cells and the expressions are differentiation-dependent.

Objective To study the effect of oleic acid on the differentiation of SW872 preadipocytes.Methods SW872 prea-(dipocytes) were cultured and induced to differentiate by 0.6 mmol/L oleic acid in vitro.After 24 h,48 h and 72 h of differentiation,the morphological changes of SW872 preadipocytes were observed and the differentiation rate was assayed by oil-red O staining.In addition,triglyceride(TG) mass was detected by chemical colorimetry methods.During the differentiation of SW872 preadipocytes,transcription factors including peroxisome proliferator activated receptor-?_2(PPAR-?_2) and CAAT/enhancer binding protein-?(C/EBP-?)(mRNA) were also measured by reverse transcription-polymerase chain reaction(RT-PCR).Results 1.SW872 preadipocytes were fibroblastic and had no obvious fat droplet in cytoplasm.However,when stimulated for 72 hby 0.6 mmol/L oleic acid,SW872 preadipocytes became more bigger and rounder and differentiated into mature adipocytes with lots of fat droplets in the cells.2.Compared with that of predifferentiation,the concentration of TG mass increased by 14 folds after 72-hour differentiation(P

Objective To explore the operation indication feasibility,operation technique and clinical effect of complex tibial plateau fractures with semilateral position through combined approaches.Methods From April 2011 to June 2013,data of 25 patients with complex tibial plateau fractures who were treated by open reduction and interal fixation with semilateral position through anterior lateral incision and an inverse L shaped incision were retrospectively analyzed.There were 15 males and 10 females,with an average age of 49.7 years old (range,30 to 70 years old).21 cases were traffic accident injuris and 4 cases were hurt by falling injuries from bicycle.All of the fracture patterns were three pillars of closed fracture of type Ⅵ according to Schatzker classification.The time at surgery was 5-21 days (mean,9.5 days) after injuries.The posterior condylar and medial condylar fractures were dealt with inverse L shaped incision,and fixated with anatomical locking plate and T shaped plate.The lateral condyle fractures were dealt with anterior lateral incision,and fixated with anatomical locking plate.Results Operating time was 150-250 min with an average time of 197.6 min.Intraoperative blood loss was 150-300 ml with an average of 232 ml.25 patients were followed-up,and the average duration of follow-up was 17.8 months (range,12-24 months).Fracture healing time was 16-24 weeks with an average of 19 weeks.At the time of the latest follow-up,X-ray showed all the knee joint had smooth surface,and there was no obvious varus or valgus deformity.One year later,the flexion of the knees achieved 115.2° (range,100°-130°),and the straighten reached 0°.The mean Rasmussen's score of all the patients were 14-18 (average,16.6),and there were excellent in 11 cases and good in 14.Bassed on the KSS score,the mean score was 88.6 (range,66-96) one year after operation.The excellent and good rate was 96％ (24/25).2 patients had fat liquefaction of anterolateral incision wound dehiscence,local skin necrosis,and they got good outcomes after debridement dressing and secondary suture.Conclusion Multi plate fixation is more effective and safty treatment for complex tibial plateau fractures which can be operated completely through fixed half lateral position,and the knee joint is allowed to do early functional exercise,achieving good clinical efficacy and good knee function.

OBJECTIVETo identify the expression characteristics of the 1700001022RIK (RIKEN cDNA 1700001022) gene in mice and explore its function by bioinformatic analysis.

METHODSUsing the expression profile of gene microarray, we detected the expression of a new testis-specific gene, 1700001022RIK, in mice. We analyzed its expression characteristics in the testis tissue and their changes in different developmental stages of the testis by RT-PCR, real-time RT-PCR, Western blot, and immunohistochemistry. We performed bioinformatic analysis using a bioinformatic software.

RESULTSThe 1700001022RIK gene was specifically expressed in the mouse testis in an age-dependent manner, most highly in the adult mice. The 1700001022RIK protein was mainly expressed in the spermatogonia, spermatocytes, and round spermatids of the adult mice. Bioinformatic analysis showed that the 1700001022RIK protein amino acid sequence had a high similarity in human and mice, which indicated that this gene was highly conserved in mammals.

CONCLUSION1700001022RIK is a testis-specific gene mainly expressed in the spermatogonia, spermatocytes, and round spermatids of seminiferous tubules, which might be involved in the regulation of spermatogenesis.

OBJECTIVETo observe the effects of electroacupuncture (EA) on circadian rhythm of temperature and melatonin (MT) in depression rats model induced by chronic stress, so as to explore the biological mechanism of EA for depression.

METHODSTwenty-four SD rats were randomly divided into a control group, a model group and an EA group, 8 cases in each one. Rats in the control group were treated with normal diet for 21 days without any treatment. In the model and EA group, rat model was established by chronic unpredictable stress combined with solitarily feeding method, and rats in the EA group was treated with EA at "Baihui" (GV 20), "Yintang" (GV 29) 1 h before stress stimulation everyday, 2 Hz in frequency and intensity was favorable with the head of rat slightly shivering. The needles were retained for 20 min, once a day for totally 21 days. After EA treatment, open-field experiment was adopted to observe the behavioral improvement; the rats temperatures were monitored at six time points (2:00, 6:00, 10:00, 14:00, 18:00, 22:00) and orbital blood sampling was collected. The level of serum MT was tested by enzyme linked immunosorbent assay. The circadian rhythm changes of temperature and serum MT in each group were compared.

RESULTSThe numbers of horizontal movement and vertical movement in the model group were obviously lower than those in the control group (both P < 0.05), while those in the EA group were significantly improved compared with those in the model group (both P < 0.01). The circadian rhythm of temperature and MT disappeared in the model group, which was improved into normal level after EA treatment.

CONCLUSIONThe electroacupuncture has regulation effects on circadian rhythm of temperature and melatonin in depression rat model induced by chronic stress.

Scoliosis is a common disease in children that causes deformity of spine and thoracic cage. The deformity not only affects the appearance, but also leads to irreversible impairment of lung function and respiratory failure in severe cases. This systematic review on publications over past 50 years demonstrates that scoliosis impairs growth and development of lungs, limits chest wall movement, and results in restrictive ventilation defect and gas exchange dysfunction. Respiratory failure occurs primarily in early-onset scoliosis and/or during latter half of gestation. Surgery corrects deformity and may slow down its progression. However, invasive procedure itself impairs lung function. Non invasive procedures prevent the deterioration of lung function rather than promoting growth and development of lungs. As a consequence, reserve of pulmonary function is recommended when surgical intervention is considered.
