OBJECTIVETo analyze the reversal effect of Buzhong Yiqi Decoction (BYD) on multidrug resistance of human adenocarcinoma of lung cell line A549/DDP, and to study its effect on the expression of survivin by using serum pharmacological methods in vitro. Methods Totally 24 SD rats were divided into the high, medium and low dose groups, and the blank control group by randomized controlled method. The high dose BYD containing serum (1. 134 g/mL, 2 mL), the middle dose BYD containing serum (0.576 g/mL, 2 mL), and the low dose BYD containing serum (0.284 g/mL, 2 mL) were prepared. The inhibitory effects of different dose and concentrations BYD on the proliferation of A549 and A549/DDP cells were detected by MTT assay, and the drug resistance reversal fold was calculated. The expression of Survivin in the two cell strains were detected respectively by immunohistochemical assay, Western blot, and immunofluorescence method.
RESULTSBYD containing serum showed obvious inhibitory effect on the growth of A549 and 549/DDP. The inhibition rates of 10% dose groups were higher than those of 5% dose groups. Besides, it gradually increased along with increased concentrations. Compared with 10% blank control group, the inhibition rate increased in 10% middle and low dose groups (P <0.05). After acted with 10% middle dose BYD containing serum, IC50, of A549 and A549/DDP were both reduced (P <0.05), reversal fold (RF) both increased. Its reversal ratio on A549/DDP cells was 2. 46, decreasing the resistance of A549/DDP to DDP. Compared with A549 in the same group, the expression of Survivin was detected to decrease by immunocytochemical assay, Western blot, and immunofluorescence method (P<0.05). Compared with 10% blank control group, the inhibition rate decreased in 10% middle dose group (P <0. 05).
CONCLUSIONS10% middle dose BYD containing serum could significantly inhibit the apoptosis of A549 and A549/DDP. Besides, it could moderately reverse the multidrug resistance of A549/DDP cells to DDP possibly through reducing the intracellular expression of Survivin and enhancing the sensitivity 549/DDP to chemotherapeutics.

OBJECTIVETo explore the effect of Buzhong Yiqi decoction on PI3K/AKT signaling pathway in spleen, stomach and lung of nude mice with lung adenocarcinoma transplantation tumor.
METHODTotally 60 nude mice were randomly divided into the blank control group, the tumor-bearing control group, the cisplatin group, the low-dose Buzhong Yiqi decoction group, the middle-dose Buzhong Yiqi decoction group and the high-dose Buzhong Yiqi decoction group. After the corresponding interventions, efforts were made to measure the transplanted tumor volume and calculate the tumor inhibiting rate. The immunohistochemical method and real time PCR were used to detect the expression of PI3K and AKT level in nude mice spleen, stomach and lung.
RESULTBuzhong Yiqi decoction of different concentrations combined with cisplatin could inhibit the growth of the transplanted tumor, with the strongest inhibitory effect in the middle-dose Buzhong Yiqi decoction group and the high-dose Buzhong Yiqi decoction group. All of the expressions of PI3K and AKT protein and gene in the spleen, stomach and lung increased, with the most significant increase in the tumor-bearing group. Along with the increase of the concentration of cisplatin and Buzhong Yiqi decoction, the expressions of PI3K and AKT gradually reduced. Compared with the tumor-bearing control group, there were statistical differences in spleen and stomach tissues (P < 0.05). Compared with the cisplatin group, the middle-dose Buzhong Yiqi decoction group and the high-dose Buzhong Yiqi decoction group showed statistical differences (P < 0.05), but without statistical difference compared with the blank control group.
CONCLUSIONAmong nude mice with lung adenocarcinoma transplantation tumor, the PI3K and AKT protein and gene expressions in spleen, stomach and lung tissues increased, which might indicated the effect of cisplatin and Buzhong Yiqi decoction in reducing PI3K and AKT expressions and the relations between the reduction degree and the concentrations of Buzhong Yiqi decoction. Cisplatin combined with Buzhong Yiqi decoction could decrease the PI3K and AKT protein and gene expression in spleen, stomach and lung, and make the pathway closer to normal, so as to protect the functions of spleen, stomach and lung, there may be target spots of Buzhong Yiqi decoction in PI3K/AKT signal pathway.

To control the quality of Humulus scandens, the quality standard was established in this study. According to the method recorded in the Appendix of Chinese Pharmacopoeia (2010 Edition) , the water and ash inspections were carried out. The component luteoloside and cosmosiin in Humulus scandens were identified and assayed by TLC and HPLC. The results showed a strong characteristics microscopic of Humulus scandens, and trichoromethane-methanol-formic acid (10: 3: 0. 3) as the mobile phase of TLC, the spots at 365 nm with a UV lamp was clear. The 16 batches of samples were analyzed by HPLC with a gradient elution of acetonitrile and phosphate solution (0.2%) at a flow rate of 1.0 mL · min(-1) and detected at 350 nm. The content of luteoloside was 0.015%- 0.651% (average 0.148%); the content of cosmosiin was 0.003%-0.118% (average 0.036%). The linear calibration curve of luteoloside and cosmosiin was acquired in the ranges of 0.011-0.364 g · L(-1) (r = 1.000 0) and 0.003-0.096 g · L(-1) (r = 1.000 0), respectively. The average recovery was 100.5% and 98.5%, respectively. The methods are convenient and reliable, which can be ap- plied for quality assessment of Humulus scandens.

OBJECTIVETo explore the clinical effects of transforaminal endoscopic spine system in surgical revision of lumbar vertebrae.
METHODSFrom January 2012 to October 2013,14 patients who needed reoperations of lumbar vertebrae were treated using transforaminal endoscopic spine system (TESSYS). There were 8 males and 6 males, aged from 27 to 84 years old with an average of (50.4 ± 18.9) years. Visual analogue scale (VAS) and Japanese Orthopaedic Association Scores (JOA) were compared before and after surgical revision. Macnab standard was used to assess the clinical effect.
RESULTSAll the patients were followed up from 6 to 27 months with the mean of 18 months. Preoperative VAS score was 6.79 ± 1.31, and in a week,3 months and 6 months after operation were 2.50 ± 1.29, 2.21 ± 1.53, 1.64 ± 1.08, respectively, which were all much lower (P < 0.01) than preoperative score. Preoperative JOA score was 12.43 ± 1.95, and the above corresponding postoperative JOA scores were 21.50 ± 3.78, 21.93 ± 4.55, 23.36 ± 4.33, respectively, which were all much higher than preoperative score (P < 0.01). According to the modified Macnab criteria, 5 patients got an excellent results, 7 good, 1 fair and 1 poor. The nerve root injury of L5 occurred in 1 case during paracentesis and no other complications were found.

Follicle-stimulating hormone (FSH) is synthesized and secreted by the anterior pituitary, which binds to its receptors expressed on the membrane of Sertoli cells in the testis to bring about spermatogenesis. With the development of DNA sequencing technology, FSH SNPs rs10835638 and FSHR SNPs rs6165, rs6166, and rs1394205 were detected, which might directly affect the expression of FSH and activity of FSHR, resulting in male spermatogenic dysfunction. This review focuses on the relationship of FSH and FSHR gene polymorphisms with male infertility.
