Objective To construct and evaluate the effects of 4C characteristic home health care services model on the health of puerperas and fetuses.Methods A total of 162 puerperas and neonates were recruited,assigned by random nember table to routine community care condition and 4C characteristic home health care condition matched on the type and degree of health condition as well as the puerperas' culture background.The health condition of puerperas and neonates were investigated and compared between the two groups 42 days after delivery.Results The incidence of breast bilges,cracked nipple,re-visit the doctor,re-admission,anxiety and depression were significantly lower in the home health care group than routine community care group [3.7％ (3/81) vs.23.5％ (19/81),2.4％ (2/81) vs.17.3％ (14/81),2.5％ (2/81) vs.16.0％ (13/81),1.2％ (1/81) vs.16.0％ (13/81),(37.35±10.72) scores vs.(41.73±10.55) scores,(39.53±13.19) scores vs.(43.94±13.44) scores,x2=21.753,18.378,8.890,11.259,t=2.621,2.108,P ＜ 0.05 or 0.01].The success breastfeeding rates,correct rate of related knowledge and master degree of newborn,self-nursing newborn skills and puerperas and relatives' satisfaction scores were significantly higher in the home health care group than routine community care group [71.6％ (58/81) vs.37.0％ (30/81),95.1％ (77/81) vs.59.3％ (48/81),91.4％ (74/81) vs.53.1％ (43/81),（92.31±3.61) scores vs.(89.83±5.43) scores,x2=21.202,29.506,29.569,t=3.423,P＜ 0.01].In additon,the rate of re-visit the doctor,re-admission and omphalitis were significantly lower in home health care group than the routine community care group [2.5％ (2/81) vs.13.6％ (11/81),6.2％ (5/81) vs.23.5％ (19/81),4.9％ (4/81) vs.22.2％ (18/81),x2=6.774,9.172,9.288,P＜0.01 or 0.05].Conclusions 4C characteristic home health care reduced the probability of breast problems and unhealthy emotions for the puerperas,reducing the severity of jaundice as well as omphalitis for fetuses,reducing the probability of re-visit the doctor and re-admission for the puerperas and neonates,which can increase patients' satisfactory and promoting the mothers and their families to master self-nursing and newborn nursing skills and the other related knowledge.

Objective To determine the significance and expression of S100A9 and NMP238 in cervical carcinoma with different concurrent chemoradiotherapy sensitivities. Methods Fresh carcinoma tissues were collected from untreated cervical carcinoma patients and preserved at -80 ℃. The tissues were classified into 2 groups:a high sensitivity group (HS) and a low sensitivity group(LS) according to their response to concurrent chemoradiotherapy. Protein was separated by 2-dimensional gel electrophoresis (2-DE). Peptide mass fingerprintings (PMF) were acquired by matrix assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) and the proteins were identified by data searching in the Mascot-database. Differential expressed proteins were assayed by Western blot and immunohistochemistry.Results Most of the gels were clear and were successfully and reproductively analyzed. Intensity and rate of S100A9 expression were higher in the HS group than in the LS group,and those of NMP238 expression were higher in the LS group than in the HS group. Conclusion S100A9 and NMP238 expression is associated with concurrent chemoradiotherapy sensitivity in cervical carcinoma.

Objective To evaluate the effects of hydroxyapatite (HA) extensively-coated prosthesis on elderly patients undergoing hip arthroplasty.Methods From February 1997 to May 1999,96 patients Were treated with hydroxyapatite (HA) coated prosthesis and followed up for their hip arthroplasty.Their results were studied clinically and roentgengraphically to evaluate chiefly their Harris scores,complications and thigh pain.The survival of prosthesis was evaluated according to Kaplan-Meier methods.Results The 60 cases were followed up for eight years on average(range,sevon to nine years).Their mean Harris scores were improved from 42 preoperatively to 90 postoperatively.Fifty-eihgt cases felt no pain at their hip,but two did at their thigh.No radiolucent lines were observed.All the prostheses achieved bony stabilization and remolding.Conclusions HA coated prosthesis can achieve fine fixation,because it helps bone conduction,resists axial force and torsion,and reduces operative risks.

This study aims to optimize the most effective component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma on lung cancer A549 using the orthogonal design method, and to investigate its effects of the component formula on cell proliferation, apoptosis and cytoskeleton in lung cancer A549 cells. The orthogonal design method was introduced to optimize the most effective component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma on lung cancer A549 cells. CCK-8 assay and Real-time cell analysis were adapted to analyze the effect of component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma on A549 cells viability at different time and dose. Cell apoptosis was measured by Annexin V- FITC/PI double staining and flow cytometry. Cell skeleton protein F-actin was detected by high content screening (HCS). The optimizing component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma for total salvianolic acid, total saponins of panax ginseng and ginseng polysaccharide doses were 5, 10, 5 mg L(-1). CCK-8 assay and real-time cell analysis demonstrated that the component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma treatment could significantly decrease the A549 cell viability in both dose- and time-dependent manner compared with control group (P < 0.01). Moreover, the increase of cell apoptosis was detected by Annexin V-FITC/PI double staining and flow cytometry when cells treated with the component formula, which indicating that the component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma could induce A549 cell apoptosis in a time-dependent manner compared with control group (P < 0.01). Furthermore, compared with control group, a significant decrease in A549 cell skeleton area was found in the component formula-exposed cells in the dose-dependent manner (P < 0.01). In summary, the component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma inhibits A549 cell proliferation by inducing cell apoptosis and decreasing cell microfilament formation. All of these results will be helpful to reveal antitumor mechanism of the component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma, which provides a basis for the exploration of antitumor mechanism of the component formula on lung cancer.

OBJECTIVETo evaluate clinical significance of waist soft tissue tension detection in treating chronic nonspecific low back pain.

METHODSFrom August 2011 to March 2012,60 patients with chronic nonspecific low back pain were divided into two groups (sliver needle group and TCM fumigation group) according to propotion of 1:1. In sliver needle group, there were 17 males and 13 females aged from 28 to 55 years old with an average age of (45.70 +/- 4.15), treated with sliver needle; In TCM fumigation group,there were 19 males and 11 females aged from 27 to 55 years old with an average age of (43.03 +/- 5.86), treated with TCM fumigation. Changes of force-displacement distance (FDD), specific absorption rate (S) of two groups were observed before treatment, 1 week and 3 months after treatment respectively, VAS scoring and Roland-Morris disability questionnaire (RMDQ) were used to access clinical effects.

RESULTS(1) VAS score of silver needle group was 4.77 +/- 0.78, 1.99 +/- 1.08 and 2.55 +/- 0.94, respectively before treatment, at 1 week and 3 months after treatment,while VAS score in TCM fumigation group were 4.43 +/- 0.61, 2.48 +/- 0.71 and 3.05 +/- 0.86, respectively. VAS score of two groups after treatment were sigificant decrease than that of before treatment (P < 0.05). There was no sigificant differences between two groups before treatment, but sliver needle group performed well in analgesia than TCM fumigation group, and had obvious differences (P < 0.05). RMDQ score of silver needle group was 13.63 +/- 1.96, 5.87 +/- 2.33 and 6.53 +/- 2.89, respectively before treatment, at 1 week and 3 months after treatment, while RMDQ score in TCM fumigation group were 13.40 +/- 2.01, 6.90 +/- 2.31, 9.23 +/- 2.87, respectively. There was no significant differences between two groups before treatment and 1 week after treatment (P > 0.05), and had obvious differences between two groups at 3 months after treatment (P < 0.01). Both groups could obvious improve dysfunction caused by chronic low back pain, and curative effect of sliver needle groups was more endurable. (2) Following-up at 3 months after treatment, FDD of multifidus, erector spinae of effected side and multifidus of healthy in sliver needle group were obvious increased (P < 0.05); In TCM fumigation group, FDD of multifidus and erector spinae on both side were increased at 1 week after treatment (P < 0.05), but had no significant meaning at 3 months after treatment on health side (P>0.05). There was no significant meaning before treatment (P > 0.05), FDD of multifidus, erector spinae of effected side in sliver needle group were obvious increased at 1 week after treatment (P < 0.05); but no obvious meaning on health side. FDD of both side in sliver needle group were obvious increased at 3 months after treatment. (3) There was correlation among differences of FDD in multifidus and erector spinae, VAS score and differences of RMDQ, and Spearman correlation coefficient R was 0.517, 0.811, 0.746 and 0.625; There was correlation between items of soft tissue tension and sympotoms, function and life quality. Conclusion:Soft tissue tension detection can effectively manifest degree of pain and dysfunction of low back, and improve objectivity of therapeutic evaluation for chronic low back pain.

Objective to investigate the value of diffusion-weighted echo-planar MR imaging in the diagnosis of head and neck lesions.Methods Fifty-seven patients with 85 head and neck lesions were enrolled in the study,including 22 patients with 22 malignant tumors,13 patients with 13 benign tumors, 13 patients with 17 cystic and liquefactive lesions(including 8 patients with 12 cystic lesions,4 patients with 4 tumor necrosis,1 patients with 1 abcess)and 33 lymph nodes.The lesions were all confirmed by operation and clinical follow up.Echo-planar difffusion-weighted imaging (DWI)was performed with different b values (0,500,and 1,000s?mm~(-2)),and the apparent diffusion coefficients (ADCs)were measured.Results Malignant and benign tumors had different characteristics in DWI with different b values.With the increase of b value,the signal intensity of tumor/spinal cord ratio decreased quickly in DWI in benign tumors,while the signal intensity of tumor/spinal cord ratio remained similar in DWI in malignant tumors.The mean ADC value of'malignant tumors[(0.78?0.24)?10~(-3)mm~2? s~(-1)] was significantly lower than that of benign tumors [(1.48?+0.20)?10~(-3)mm~2?s~(-1)] (t = 8.9,P

Objective: To investigate the effect of UGT2B7 A268G and UGT2B7 G211T genetic polymorphism on serum drug concentration of valproic acid (VPA).
Methods:Genetic polymorphisms of UGT2B7 A268G and UGT2B7 G211T were tested in 248 epileptic patients by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP). Data including basic information, epilepsy type, times and doses of drug, treatment response and liver and kidney functions were collected. Statistical analysis was performed by SPSS 13.0 through multivariate linear regression, one-way ANOVA,χ2 test, and paired T-test.
Results:Based on multivariate linear regression, there was no significant difference between gender, age, or body mass index and VPA, but concentration-to-dose ratios (CDRs) were positively correlated with VPA. hTe genetic polymorphisms of UGT2B7 A268G and UGT2B7 G211T were consistent with Hardy-Weinberg equilibrium. UGT2B7-268A>G allele frequency distribution A was 30.05%, and G was 69.95%. Variance analysis showed that serum drug concentration was significantly different in the genotype of AA, AG, or GG (F=5.477, P=0.005). Further analysis of paired T test showed that AA type was significantly different from GG type (P=0.048), and that serum concentration of AA type was much higher than that of GG type, while no signiifcant difference between AA type and AG type, GG type and AG type. UGT2B7 G211T allele frequency distribution G was 77.24%, and T was 22.58%. hTere was no signiifcant difference in standardized serum concentration among genotypes of GG, GT, and TT.
Conclusion:hTis study reveals UGT2B7 A268G genetic polymorphism distribution in Chinese epilepsy population. UGT2B7 A268G plays an important role in VPA’s metabolism, and has certain effect on VPA’s serum concentration. Epilepsy patient with this genotype should be adjusted the dose of VPA to make a therapeutic effect.
