Objective To investigate the positive detective rate of interlobar node in the operation of non-small cell lung cancer (NSCLC), and to compare the effect of interlobar node dissection by video-assisted thoracoscopic surgery (VATS) with thoracotomy in treatment of lung cancer. Methods 108 patients with NSCLC who received the surgery by the same group of thoracic surgeons were collected from Aug 2012 to Mar 2016 in Guangdong Medical University Affiliated Kaiping Central Hospital. The positive transfer and detective rates of interlobar node in patients with different clinical and pathological stage were analyzed. Then the patients were divided into traditional open thoracotomy group and VATS group according to the operation mode, meanwhile, the number of interlobar nodes dissection in the two groups were compared. Results The positive transfer rates of the interlober nodes in patients with different clinical stage were ⅠA 5.7 % (2/35),ⅠB 5.0 % (1/20), ⅡA 14.3 % (3/21), ⅡB 13.3 % (2/15), ⅢA 29.4 % (5/17); For patients with different pathological T stage were T1A 8.3 % (2/24), T1B 9.1 % (2/22), T2A 12.9 % (4/31), T2B 14.3 % (2/14), T3 21.4 %(3/14), T4 33.3 % (1/3), and over-all transfer rate was 13.0 % (14/108). In pathology stage and pathology T stage, the number of interlober nodes had no statistical difference in traditional open thoracotomy group and VATS group (all P>0.05). Conclusions Even in the early clinical stage, the transfer of interlobar node may be positive. The transfer rate of interlobar node is correlated positively with pathology T stage. VATS can achieve the same effect in interlobar node dissection compared with the traditional approach.

Objective To investigate the feasibility and stability of medical gas suction feeding device for copying the model of respiratory failure in dogs. Methods The self-designed medical gas suction feeding device was used to establish the model of respiratory failure in dogs. After regulating the proportion of oxygen (O2), carbon dioxide (CO2) and nitrogen (N2), the fraction of inspiration O2 (FiO2) was decreased, while the forced inspiratory carbon dioxide (FiCO2) was increased. At the same time, the breathing out pathway was open to make the arterial oxygen partial pressure p (O2) and arterial blood carbon dioxide partial pressure p (CO2) reached and stabilized in a stable condition. The arterial blood samples between default state and 1 hour, 2 hour after modeling were collected to detect the blood gas index. Results One hour after the establishment of model, the p (O2) was≤60 mmHg (1 mmHg=0.133 kPa), and p (CO2) was≥50 mmHg (1 mmHg=0.133 kPa), which suggested that the dog model of respiratory failure was established successfully. Compared with the basic state, data of pH, oxygen content, oxygen saturation (SaO2) and residual alkali (BE) were decreased at 1 hour and 2 hour after modeling (P < 0.05). The p (O2), oxygen content, SaO2 were decreased in 2 hour after modeling compared with those of 1h after modeling (P<0.05). There were no significant differences in pH, p (CO2), TCO2, HCO3-and BE between 1 hour and 2 hour after modeling (P > 0.05). Conclusion Under the regulation of the medical gas suction feeding device, the respiratory failure state of large experimental animals is successfully established.

BACKGROUND:A large amount of studies have confirmed that synovial mesenchymal stem cells have the similarity in cellmorphology, immune phenotype, colony forming ability and differentiation potential with bone marrow mesenchymal stem cells. But bone marrow mesenchymal stem cells are better than synovial mesenchymal stem cells in the ability to differentiate into cartilages. OBJECTIVE:To discuss the possibility of using synovial mesenchymal stem cells as seed cells for meniscal tissue engineering. METHODS:The synovial mesenchymal stem cells were isolated from rabbit synovial tissues with limiting dilution monoclonal culture method, and then the cells were purified. The morphology, ultrastructure, molecular phenotype, proliferation kinetics, karyotype and tumorigenicity of the in vitro cultured cells were analyzed. RESULTS AND CONCLUSION:The synovial mesenchymal stem cells isolated from the rabbit synovial cells had high proliferation capacity during in vitro monolayer culture. The synovial mesenchymal stem cells grew to peak at 6 days, and the doubling time was (30.2±2.4) hours. Flow cytometry results showed the synovial mesenchymal stem cells could express some molecular makers of mesenchymal stem cells, such as CD44 and CD90. DNA contents check, karyotype test and oncogenicity test confirmed isolated and purified synovial mesenchymal stem cells were the normal diploid cells without tumorigenicity, so the cells can be used as seed cells for meniscal tissue engineering.

BACKGROUND:Smal intestinal submucosa is characterized as antimicrobial activity, good biocompatibility, bio-mechanical properties, and rapid degradation in vivo, similar to the extracellular matrix of meniscal
fibrochondrocytes.
OBJECTIVE:To observe whether there exists a good histocompatibility between smal intestinal submucosa and synovial mesenchymal stem cells.
METHODS:Smal intestinal submucosa was treated with physical and chemical treatment. And hematoxylin-eosin staining and scanning electron microscopy observation were performed. Then, smal intestinal submucosa extracts were prepared for the fol owing experiments. (1) Pyrogenic test:smal intestinal submucosa extracts were injected into the ear vein of New Zealand white rabbits. (2) Skin sensitization test:smal intestinal submucosa extracts, paraformaldehyde solution and normal saline were respectively injected intradermal y into New Zealand white rabbits. (3) General toxicity test:smal intestinal submucosa extracts and normal saline were respectively injected into the ear vein of New Zealand white rabbits. Smal intestinal submucosa was co-cultured with osteogenic rabbit synovial mesenchymal stem cells, and smal intestinal submucosa cultured alone served as control. RESULTS AND CONCLUSION:There were some intestinal mucosal epithelial cells, fat cells and other cells adhered onto the surface of smal intestinal submucosa after physical treatment. While, the amount of residual cells decreased sharply after chemical treatment. But the main structure and the component had not been changed. The surface of smal intestinal submucosa was smooth and no cells remained, and there was a three-dimension network spatial structure. The porosity was 80%. Smal intestinal submucosa is a non-toxic, nonirritating, non-immunogenic biomaterial with very good biocompatibility, which has a good histocompatibility with rabbit synovial mesenchymal stem cells.

OBJECTIVETo observe the therapeutic efficacy of Qianggu Granule (QGG), Diacerein Capsule (DC), and QGG + DC in treating knee osteoarthritis (KOA, belonging to Gan-Shen insufficiency induced vein stasis syndrome), and to explore the clinical advantages of QGG + DC.

METHODSNinety patients in line with the diagnosis standard were randomly assigned to three groups, i. e., the QGG group (30 case, treated by QGG), the Western medicine treatment group (30 case, treated by DC), and the combination therapy group (30 case, treated by QGG +DC). Then the patients' symptoms and signs were scored. Meanwhile, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), tumor necrosis factor alpha (TNF-alpha), comprehensive efficacy, and adverse reactions, etc. were assessed.

RESULTSThe ache could be obviously alleviated, the patients' joint function could be improved, and their quality of daily activities could be elevated in all the 3 groups. There was statistical difference in the symptoms and signs scores, CRP, ESR, and TNF-alpha before and after treatment (P < 0.05). Better effects were obtained in the combination therapy group (P < 0.05). As for the comprehensive efficacy, it was better in the QGG + DC group than in the QGG group and the DC group, showing statistical difference (P < 0.01).

CONCLUSIONSThe comprehensive therapeutic efficacy of applying QGG + DC in treating KOA (belonging to Gan-Shen insufficiency induced vein stasis syndrome) was superior to using QGG or DC alone. Besides, no obvious adverse reaction occurred.

OBJECTIVETo explore the correlation between hand and face-mouth, so as to provide nerve reflex basis for the theory "Hegu (LI 4) regulates face and mouth".

METHODSSeven hundred and sixty-three participants who met the inclusive criteria were divided into different age groups. The skin around participants' thenar eminence was gently scraped to be observed whether there was an involuntary movement around the face or mouth, which was palmomental reflex. The results of palmomental reflex were recorded.

RESULTSThe total occurrence rate of palmomental reflex was 46.26%. For those who were 0 to 1 years old, the palmomental reflex was all positive; for those who were 21 to 36 years old, the positive rate was 20.45%, which was the lowest; for those who were 65 to 85 years old, more than half of them were positive. The majority of those who were 0 to 2 years old were bilateral positive palmomental reflex, while the majority of those who were 65 to 85 years old were unilateral positive palmomental reflex.

CONCLUSIONThere is a certain connection between hand and face-mouth. The occurrence rate of palmomental reflex changes from high to low over age increasing, and then changes from low to high with the aging, presenting a "high-low-high" U-shaped curve, which is possible related to the growth and recession of nervous system.
