BACKGROUND:It is an important issue of alveolar ridge preservation after tooth extraction. Because of the limited treatment and geographical conditions, lack of awareness of oral health, many local people in frontier areas in Xinjiang have poor alveolar ridge that is not of timely repair after tooth extraction. Thus, it is important to find a suitable local and efficient way to save the residual ridge, which has a more practical clinical value. OBJECTIVE:To investigate the feasibility of nano-colagen artificial bone used for alveolar ridge preservation in the Kazakh in Xinjiang Tacheng Region, China. METHODS: Sixty-eight Kazakh patients with bilateral extraction from Tacheng region, Xingjiang Uygur Autonomous Region, China were selected in a self-controled trial. According to the principle of a minimum alocation imbalance index, the experimental side and control side of extraction patients were confirmed. In the experimental side, nano-colagen artificial bone was implanted; while, conventional treatment was done in the control side. Multi-slice spiral CT was used to scan the regions of extraction interest to measure the relative gray value of alveolar bone mineral density immediately and 3 months after implantation. RESULTS AND CONCLUSION:Immediately after implantation, tooth extraction sockets were visible on CT images both in the experimental and control sides; but after 3 months, the extraction sockets became unclear on the CT images, and CT values were close to those of the surrounding alveolar process, but bone tissues were ful of the bone graft area in the experimental side. The alveolar bone mineral density was higher in the experimental side than the control side at 3 months after implantation. These findings indicate that the nano-colagen artificial bone has good clinical achievement in alveolar ridge preservation in the Kazakh in Xinjiang Tacheng Region.

Objective To observe the effects of passive movement on the functional outcome after occlusion of the middle artery in the brain and reperfusion, and to explore the molecular mechanisms involved. Methods Cerebral infarction models were established in rats using left middle cerebral artery occlusion ( MCAO). The survivors were randomly divided into a passive movement group and a natural recovery group. There was also a sham-operated group and a normal group. Passive movement treatment (twice a day, twenty min per time) was started at different times after reperfusion. The expression of brain-derived neurotrophic factor (BDNF) and B cell lymphoma/leukemia-2 gene (Bcl-2) were determined using real-time PCRs. Results Expression of BDNF and Bcl-2 was detected a-round the infarction area in both groups. The expression of BDNF and Bcl-2 was highest in the sub-groups where passive movement was begun 24 or 48 h after the operation. Conclusions The expression of BDNF and Bcl-2 in the brain peaks when daily, moderate intensity passive movement is administered beginning 24 to 48 h after reperfusion. Passive movement might have a protective and rehabilitative effect after cerebral infarction.

Objective:To analyze the distribution of UGT1A1 gene polymorphisms in Chinese Han patients with extensive-disease small cell lung cancer(ED-SCLC),and evaluate the correlation between UGT1A1 gene polymorphisms and toxicity and efficacy of irino-tecan(CPT-11) based regimen in the patients with ED-SCLC. Methods: The analysis of UGT1A1?28 and UGT1A1?6 gene poly-morphisms was performed in 67 patients with ED-SCLC admitted in our hospital from June 2011 to January 2013. The 67 cases with ED-SCLC treated with irinotecan(CPT-11) based regimen were enrolled to observe the adverse events and efficacy during the chemo-therapy, including objective responserate rate ( ORR) , progression free survival ( PFS) and overall survival ( OS) . The incidence of different genotypes was compared. Results:The distribution of UGT1A1 genotypes in the 67 patients was follows:UGT1A1?28 wild-type (WT) genotype TA6/6 (56, 83. 6%), heterozygous genotype TA6/7 (11, 16. 4%);UGT1A1?6 wild-type (WT) genotype G/G (45,67. 2%), heterozygous genotype G/A (22,32. 8%). No significant difference of PFS and OS was observed between the differ-ent genotypes. The incidence of grade 3 and 4 delayed diarrhea and neutropenia in the patients carrying UGT1A1?6 G/A was higher than that in those with WT genotype (36. 4% vs. 6. 6%, P<0. 05;27. 2% vs. 4. 4%, P<0. 05, respectively). The incidence of grade 3 and 4 thrombocytopenia in the patients carrying UGT1A1?28 TA6/7 was higher than that in those with WT genotype (27. 2%vs. 1. 8%, P<0. 05). The patients simultaneously carrying UGT1A1?28 TA6/7 and UGT1A1?6 G/A were prone to suffering 3 and 4 delayed diarrhea and neutropenia. Conclusion: UGT1A1 polymorphisms may predict the adverse events of CPT-11 in ED-SCLC, while can not predict the efficacy of CPT-11.

Background Compare with the lamellar laser refractive surgery,the laser slip on the surface operation is a better method in the correct of refractive error without the flap-related complications.However,whether to remain corneal epithelial flap and its influence for epithelial healing and visual restoration are still under investigation.Objective The aim of this study was to compare the short-term clinical efficacy of epipolis laser insitu keratomileusis (Epi-LASIK) and flap-free Epi-LASIK for correction of refractive error in high myopia.Methods The paired control design was adopted.Sixty eyes of consecutive 30 patients with high myopia were collected in this study.The written consent form was obtained from each patients prior to operation.Regular EpiLASIK was performed in the right eyes and the flap-free Epi-LASIK was carried out in the left eyes.Patients were followed-up for one month.The postoperative ocular irritation symptoms were scored,and the healing period of corneal epithelium and uncorrected visual acuity were examined at 1,3 and 5 days after operation.The naked visual acuity,diopter,best corrected visual acuity and the grading of haze were recorded and compared between the two groups at one month after operation.Results After surgery,the scores of corneal irritation were 3.13 ±0.43 and 3.30±0.47on the first day,showing insignificant differences between these two groups (t =- 1.54,P＞0.05 ).However,there existed statistically significant difference in the scores of corneal irritation on the third day after operation between the two groups (t =- 17.95,P＜0.01 ).The average time of corneal epithelial healing were (2.58 ±0.49 ) days in the flapfree Epi-LASIK group and ( 3.98 ±0.74) days in Epi-LASIK group with the significant difference between them (t=-11.36,P＜0.01 ).There was no statistical difference in uncorrected visual acuity in the first day (0.59±0.12 vs 0.58±0.11,t=0.39,P＞0.05),the fifth day (0.69±0.08 vs 0.67±0.09,t=0.84,P＞0.05) and 1 month (t =-1.90,P＞0.05 ).No significant difference was seen in the diopter between the two groups in 1 month after surgery (-1.03±0.45 vs -1.07 ±0.38,t =-0.31,P＞0.05 ).The eye numbers of corneal haze for 0 grade were 27 ( 90.00％ ) and over the 0.5 grade were 3 ( 10.00％ ) in flap-free Epi-LASIK group respectively,and those of corneal haze for 0 grade were 26(86.66％ ) and above the 0.5 grade were 4 (13.33％) in Epi-LASIK group respectively,showing a considerably difference between the two groups (x2 =0.0031,P＞0.05).Conclusions Both the flapfree or reserved epithelial Epi-LASIK allow the safe and effective correction of refractive error in high myopia,showing good predictability and stability in short term.Flap-free Epi-LASIK can relieve the corneal irritation symptom and accelerate the healing of corneal epithelium and recovery of visual acuity.

The aim of this study was to elucidate the scientific connotation of Bombyx Batryticatus processing with wheat bran under high temperature. The contents of soluble protein extracted from Bombyx Batryticatus and its processed products and the limited content of AFT in Bombyx Batryticatus and the processed one were compared. The concentration of protein was measured with the Bradford methods and the difference of protein between Bombyx Batryticatus and its processed products was compared by SDS-PAGE analysis. Aflatoxin B1, B2, G1, and G2 were determined by reversed-phase HPLC. The results showed that the soluble protein content of Bombyx Batryticatus and its processed products were (47.065 +/- 0.249), (29.756 +/- 1.961) mg x g(-1), correspondingly. Analysis of protein gel electrophoresis showed that there were no significant differences between the crude and processed one in protein varieties. 6 bands were detected: 31.90, 26.80, 18.71, 15.00, 10.18, 8.929 kDa. Below 10 kDa, the color of bands of the processed one was deeper than the crude one, which demonstrate that macromolecular protein was degradated into micromolecule. The content of AFG1, AFB1, AFG2, AFB2 were 0.382, 0.207, 0.223, 0.073 g x kg(-1), not exceeded 5 microg x kg(-1) while the processed one was not detected. Through processing with wheat bran under high temperature, the content of soluble protein in Bombyx Batryticatus decreased, the processing purpose for alleviating drug property was achieved. Meanwhile, the limited content of aflatoxins were reduced or cleared by processing procedure or absorbed by processing auxillary material, adding the safety of the traditional Chinese Medicine. In conclusion, as a traditional processing method, bran frying Bombyx Batryticatus was scientific and reasonable.

OBJECTIVETo explore therapeutic effect and action mechanism of regulating spleen-stomach needling on diabetic nephropathy (DN).

METHODSUsing multi-centric, randomized, controlled and blind principles, 144 cases of DN were divided into an observation group and a control group according to random digital tab, 72 cases in each one. Based on regular treatment of diabetes, the regulating spleen-stomach needling was applied at Zhongwan (CV 12), Quchi (LI 11), Hegu (LI 4) and Xuehai (SP 10), etc. in the observation group while Shenshu (BL 23), Taixi (KI 3), Sanyinjiao (SP 6), Yanglingquan (GB 34), etc. were selected in the control group by reference of Acupuncture and moxibustion. The treatment was given twice a day, six days as a treatment session with interval of one day between sessions. Totally six weeks were required. Changes of clinical symptoms and signs, fast blood glucose (FBG), urinary albumin excretion rate (UAER), beta2-microglobulin (beta2-MG), monocyte chemotactic protein-1 (MCP-1), lymphocyte membrane cholesterol, propanediol (MDA), PCO, 8-hydroxydeoxy guanosine (8-OHdG), superoxide dismutase (SOD), CD3+, CD4+, CD8+, and CD4+/CD8+ were observed before and after treatment in two groups.

RESULTSAs for improving clinical symptoms and signs, total effective rate was 84.29% (59/70) in the observation group and 55.56% (40/72) in the control group, which had statistical difference between two groups (P<0.01). As for regulating glycometabolism [(6.25 +/- 0.32) mmol/L vs (8.09 +/- 0.63) mmol/L], reducing UAER [(154.43 +/- 55.14) mg/24h vs (268.91 +/- 77.65) mg/24h], restraining over-expression of MCP-1 [(137.59 +/- 36.15) pg/mL vs (166.89 +/- 42.82) pg/mL], regulating level of oxidative stress, prohibiting oxidation of protein and adjusting quantity and activity of T lymphocyte subgroup, the observation group was superior to the control group (P< 0.05, P<0.01).

CONCLUSIONThe regulating spleen-stomach needling is an effective method for treatment of DN, which cold improve glycometabolism disturbance-induced progressive kidney injury, recover glomerular filtration, reduce urinary albumin excretion rate, restrain overexpression of MCP-1, adjust level of oxidative stress, prohibit oxidation of protein, increase protectiveness of membrane, adjust quantity and activity abnormity of T lymphocyte subgroup, leading to repairing lymphocyte damage and improving immune expression to delay kidney damage.
