Diabetic peripheral neuropathy (DPN) is the most common complication of diabetes mellitus in nervous system. However, the pathogenesis is still unkown. Therapeutic options are mainly pathogenetically oriented therapy and symptomatic therapy. With an increasing understanding of the pathogenesis of DPN, many new therapies have emerged. Comprehensive therapy targeting different pathogenesis will be frequently applied in the future. In this article, the common therapy and advance in treatment of DPN are reviewed.

Inoculant the examine-needed germ on a flat panel of synthetic medium, and placed paper slices, which had being saturated by different kinds of sugar, on the medium to carry out the experiment of microorganic auxanography. Its result was compared with that of the traditional method, the sugar-grain method. The comparison showed that the former was better than the latter for its more definite result and more convenient operation.

OBJECTIVETo observe the change of the salivary occult blood after periodontal mechanical therapy, and to assess the correlations between salivary occult blood and the level of volatile sulphur compounds (VSC) in oral cavity, periodontal clinical parameters, respectively.

METHODSFifty patients with gingivititis, mild or moderate periodontitis were included. The level of VSC were measured by Halimeter(®) and salivary occult blood was tested by Perioscreen(®) before periodontal examination. Then full mouth plaque index (PLI), probing depth (PD), bleeding index (BI) were charted. Attachment loss (AL) of the Ramfjörd teeth were recorded lastly. Intensive periodontal mechanical therapy was conducted including oral hygiene instruction, scaling and root planing (SRP). Four weeks after SRP, the same examinations were repeated.

RESULTSSalivary occult blood was significantly correlated with BI (r = 0.294) and PLI (r = 0.308) before periodontal therapy (P < 0.01), and also significantly correlated with VSC level (r = 0.386), PLI (r = 0.456), BI (r = 0.352), AL (r = 0.325) after therapy (P < 0.05). The improvement of VSC level [211.0 (111.0 - 389.5) × 10⁻⁹ vs 100.0 (46.3 - 165.3) × 10⁻⁹], the clinical periodontal parameters including PLI [(1.3 ± 1.0) vs (0.4 ± 0.6)], PD [(3.7 ± 1.5) mm vs (2.7 ± 0.9) mm], BI [(1.8 ± 1.2) vs (0.4 ± 0.7)] and AL [(1.0 ± 1.1) mm vs (0.1 ± 0.5) mm after the treatment was statistically significant (P < 0.001). However, standing on the viewpoint of salivary occult blood changes from positive before therapy to negative after therapy, only 80% (40/50) individuals were totally cured. VSC level in oral cavity and periodontal clinical parameters significantly decreased (P < 0.001) following the trends from strong positive, weak positive, to negative results of salivary occult blood test.

CONCLUSIONSSalivary occult blood was correlated with VSC level in oral cavity of periodontal treated patients. It may be an objective parameter to evaluate the gingival inflammation and the efficacy of the periodontal therapy at individual level.

OBJECTIVETo describe the temporal trends in the mortality rate of gastric cancer during the period of 1988 and 2010, and to predict the gastric cancer mortality between 2016 - 2020.

METHODSThe data of gastric cancer mortality in Linzhou city between 1988 and 2010 was extracted from the cancer registry, including a total of 11 714 cases, covering 22 447 073 person-years. The mortality rate of gastric cancer of each 5-year period was calculated by sub-site and gender. Age-standardized rate (ASR) was calculated using the Chinese standard population in 1982. Intrinsic estimator (IE) model was used to fit the mortality trend by sub-site and gender, and to predict the mortality of gastric cancer in Linzhou city between 2016 and 2020.

RESULTSFrom 1988 to 2010, the gastric cancer mortality in Linzhou city was 52.18/100 000 (11 714/22 447 073) with the ASR at 49.23/100 000; the mortality in male was 67.02/100 000 (7678/11 455 512) with ASR at 68.68/100 000 while the mortality in female was 36.72/100 000 (4036/10 991 561) with ASR at 32.12/100 000. The mortality of cardia carcinoma was 27.87/100 000 (6257/22 447 073) with the ASR at 26.37/100 000; while the mortality of non-cardia carcinoma was 24.31/100 000 (5457/22 447 073) with the ASR at 22.86/100 000. The ASR of gastric cancer during 1988 - 1990 was 63.37/100 000 (1653 cases) and decreased by 28.34%, to 45.41/100 000 (2622 cases) during 2006 - 2010. The IE model showed that the birth cohort effect decreased greatly. The mortality risk of cardia carcinoma in population born after 1950s, decreased significantly; and the mortality risk of non-cardia carcinoma in population born in 20 century continually decreased. The death of gastric cancer among the population over 30 years old was predicted to be 3626 cases, increasing by 40.60% compared with the number between 2006 and 2010 (2579 cases). Among them, the mortality of cardia carcinoma increased by 51.89% (predicted number between 2016 and 2020 was 2456 cases, and 1617 cases between 2006 and 2010), and the mortality of non-cardia carcinoma increased by 21.62% (predicted number between 2016 and 2020 was 1170 cases, and 962 cases between 2006 and 2010).

CONCLUSIONThe mortality rate of gastric cancer in Linzhou city showed a decreasing trend during the period of 1988-2010, being mainly attributed to the cohort effect. However, the mortality will still increase in the future, between 2016 and 2020.

OBJECTIVETo observe the effects of fenvalerate (Fen) on ovarian calcium homeostasis.

METHODShGLCs were obtained from pre-ovulatory follicles in an in vitro fertilization program, and were cultured for 72 hours. Changes in cellular [Ca(2+)]i induced by Fen in hGLCs were detected with laser scanning confocal microscopy (LSCM) by using the fluorescent Ca(2+) indicator fluo-3/AM. SD female rats were divided into four groups (control, 1/15LD(50), 1/50 LD(50) and 1/250 LD(50)) in experiment. The activity of ovarian Ca(2+)-ATPase and phosphorylase A (P-a) and the contents of calmodulin (CaM) were assessed after a 30-day Fen exposure. In addition, serum estradiol-17 beta (E(2)) and progesterone (P(0)) concentration were measured by radioimmunoassay, which the sampling rats were ensured at diestrus stage before killed according to vaginal smear.

RESULTS20.0 and 2.0 micromol/L Fen induced the increased of [Ca(2+)]i in hGLC. This [Ca(2+)]i increase mostly resulted from Ca(2+) influx in the studied concentration. Fen had shown the inhibition effects on activity of Ca(2+)-ATPase in 1/250 LD(50) group (P < 0.001) while the activity of phosphorylase A (P-a) in treated groups had significantly enhanced than those of in control. The contents of CaM in ovaries were found to be increased in treated groups. E(2) in 1/250 LD(50) group were higher while P(0) in 1/15 LD(50) group were significantly lower (P < 0.05).

CONCLUSIONExposure to Fen interferes the serum steroid hormone concentrations partly through calcium signal pathway.

OBJECTIVETo estimate the number of death from malignant tumor and to assess the completeness of cancer registry data using the capture-recapture method.

METHODSData about death form malignant tumor were collected during the period of 2004 and 2005 from cancer registry, civil administration and police registries in Linzhou. Cases in every source were matched on the address, name, sex, ID card, date of death, cause of death. A 3-source log-liner poisson model was used to estimate the real number of death from malignant tumor during the period of 2004 and 2005 in Linzhou.

RESULTSThe real number of death from malignant tumor that estimated by capture-recapture method was 3140 (95% CI: 3124 - 3161) during 2004-2005 year in Linzhou. Underreported number by source linkage was 71. Log-liner model demonstrated positive dependence between the 3 sources, implying that 2-source model would underestimate missing cases. Using the mortality number estimated by the capture-recapture as the denominator, under-reporting rate of cancer registry was 6.6%.

CONCLUSIONIt is feasible to estimate the real number of death from malignant tumor and to correct data bias by applying the capture-recapture method.

OBJECTIVETo establish the visual patch clamp whole-cell recording technique and study the properties and functional significance of muscarinic receptor-mediated currents in rat medial vestibular nucleus neurons (MVNn).

METHODSBrain slices containing the MVN were prepared from fifteen Wistar rats. By combining infrared differential interference contrast (IR-DIC) technique and CCD-Camera system with visual patch clamp whole-cell recording technique, twenty healthy neurons were located and muscarinic receptor-mediated currents in rat MVNn were observed and analyzed.

RESULTSVisual patch clamp technique can be used to make direct localization and to make sure of active neuron. In MVNn, a comparison of the current-voltage relationships before and during the application of muscarine, which revealed an increase in the slope of the I-V curve and the reversal potential for this response lay at (-88.4 +/- 4.9) mV (x +/- s), indicates that the activation of muscarinic cholinergic receptors leads to a decrease in potassium current. The test in the voltage sensitivity of the muscarine-induced response, which showed that the effect had a linear current-voltage relationship and reversed at (-86.7 +/- 3.5) mV, indicates that the potassium current blocked by muscarine corresponds to the voltage-insensitive leak potassium current.

CONCLUSIONSVisual patch clamp technique, which was considered better than blind patch clamp technique, can improve the success of sealing process. By the analysis of muscarinic receptor-mediated currents, the data provide support that muscarinic cholinergic mechanisms play a prominent role in the modulation of the excitability of MVNn and also offer a new idea for the efficacy of anticholinergic drugs.

AIM:To investigate the effect of interference in Yes-associated protein(YAP)expression on blad-der cancer cell apoptosis and its mechanisms.METHODS:Bladder cancer cell line T-24 was used as the target and divid-ed into control group(no treatment),small interfering RNA negative control(siRNA-NC)group,and YAP siRNA group. The expression levels of YAP at mRNA and protein levels in the transfected cells of each group were detected by real -time PCR and Western blot,respectively.The cell viability was measured by MTT assay.The apoptosis was analyzed by flow cytometry.The protein expression levels of β-catenin and c-Myc were determined by Western blot.The cells in YAP siRNA group were treated with Wnt/β-catenin signaling pathway inhibitor FH 535, and then the cell viability and apoptosis were analyzed by MTT assay and flow cytometry,respectively.RESULTS:The expression of YAP at mRNA and protein levels in YAP siRNA group was significantly lower than that in control group(P<0.05).The cell viability and the expression levels of c-Myc and β-catenin in YAP siRNA group were significantly lower than those in control group(P<0.05),while the apoptotic rate was significantly higher than that in control group(P<0.05).The cell viability in YAP siRNA+FH535 group was decreased significantly,while the apoptotic rate was increased as compared with YAP siRNA group(P<0.05). CONCLUSION:Interfering with the expression of YAP inhibits the viability of bladder cancer cells by inhibiting the Wnt /β-catenin signaling pathway,thus promoting apoptosis of bladder cancer cells.

OBJECTIVE: To determine the protective effects and mechanism of ulinastatin on the lung injury during cardiopulmonary bypass (CPB). METHODS: Thirty patients with rheumatic heart disease (RHD) were divided into 2 groups randomly. The ulinastatin group (Group U, n = 15) received 1 x 10(4)U/kg ulinastatin intravenously before the CPB and the same amount of ulinastatin was added into the primary solution. The control group (Group C,n = 15) received normal saline instead of ulinastatin. A brochioalveolar lavage was performed at 2 h after the cardiopulmonary bypass. Polymorphonuclear neutrophil elastase, tumor necrosis factor-alpha and MDA contents in the brochioalveolar lavage fluids were measured, and the lung oxygenate index was measured preoperatively and at 1 and 4 h after CPB termination. RESULTS: Polymorphonuclear neutrophil elastase, tumor necrosis factor-alpha and MDA contents of Group U in the brochioalveolar lavage fulids were significantly lower than those of Group C (P < 0.05), and the lung oxygenate index of Group U at 1 and 4 h after CPB termination was also significantly lower than that of Group C. A significant increase of lung oxygenate index occurred in both groups at 1 and 4 h after CPB when compared with the same group at the baseline before CPB (P < 0.05). CONCLUSION Ulinastatin has the protective effects on the lung injury during CPB by decreasing polymorphonuclear neutrophil elastase, alleviating lung inflammatory reaction and reducing oxygen free radicals.

OBJECTIVETo analyze the cancer incidence and mortality of Henan province in 2009.

METHODSOn basis of the criteria of data quality from the National Central Cancer Registry (NCCR), data from 6 registries in Henan province were evaluated, covering 6 061 564 people, accounting for 6.45% of the total population in Henan in 2009. There were 3 104 991 people of males, and 2 956 573 people of females. The incidence, mortality, 10 most common cancers, constitution and cumulative rate (0-74 years old) were then calculated. The age-standardized rate was calculated and adjusted by the Chinese standard population in 1982 as well as the Segi's world standard population.

RESULTSThere were 12 091 new diagnosed cancer and 8040 death cases registered in Henan province in 2009. The rate of pathological diagnosis was 68.2% (8246/12 901) and only 1.75% (2116/12 901) had death certificates. The ratio of mortality and incidence was 0.66 (8040/12 091). The incidence rate was 199.47/100 000 (12 091/6 061 564) in total, and it was 216.36/100 000(6718/3 104 991) in males and 181.73/100 000(5373/2 956 573) among females. The standardized incidence by Chinese population was 126.50/100 000 and it was 166.08/100 000 by world's population. The cumulative rate was 19.95% between 0 and 74 years old. The incidence was the highest in Linzhou city, whose standardized incidence was 156.87/100 000 by Chinese population and the incidence was the lowest in Shenqiu city, whose standardized incidence was 104.82/100 000 by Chinese population. The morphology verified cases accounted for 68.2% (8246/12 091), death certification cases only accounted for 1.75% (2116/12 091), and mortality to incidence ratio was 0.66 (8040/12 091). The crude incidence in cancer registration areas of Henan province was 199.47/10 000 (12 091/6 061 564), 216.36/10 000(6718/3 104 991) for males, 181.73/10 000 (5373/2 956 573) for females, age-standardized incidence rates by Chinese standard population and by world standard population were 126.50/10 000 and 166.08/10 000 with cumulative incidence rate (0-74 age years old) of 19.95%. The crude mortality in cancer registration areas of Henan province was 132.64/100 000 (8040/6 061 564), separately 160.58/100 000 (4986/3 104 991) for males and 103.30/10 000 (3054/2 956 573) for females. The age-standardized mortality rates by Chinese standard population and by world's standard population were 78.41/10 000 and 107.49/10 000. The cumulative mortality rate (0-74 age years old) was 12.18%. The mortality rate was the highest in Linzhou city, whose standardized rate was 93.35/100 000 by Chinese population, and the lowest mortality rate was in Yuzhou city, whose standardized rate was 67.95/100 000. The most common cancers were lung cancer, esophageal cancer, gastric cancer, liver cancer, breast cancer, rectum cancer, brain nervous system cancer, colon cancer, cervical cancer and uterus cancer, all of which accounted for 82.23% (9943/12 091) of the registered cancers.Lung cancer, esophageal cancer, gastric cancer, liver cancer, breast cancer, rectum cancer, brain nervous system cancer, pancreas cancer, colon cancer and gallbladder carcinoma were the major causes for the death, accounting for 86.30% (6938/8040) of all cancer deaths.

CONCLUSIONBoth incidence and mortality of cancer in Henan province were lower than the level in China, prevention and control should be implemented based on practical situation.
