Objective To explore the relationship between the proliferation of neural stem cells (NSCs)and the expression of β-catenin protein in neonate rats with hypoxic ischemic brain damage (HIBD) after hyperbaric oxygen (HBO) therapy. Methods One hundred and eighty Sprague-Dawley rats aged 7 days were randomly divided into a normal control group (CON) , a HIBD model group and a HBO treatment group. The HIBD model was induced using Rice's method. Beginning 3h after the HIBD, HBO was administered to the HBO treatment group at 2 atmospheres for 60 min, once daily for 7 days. The HIBD model group was not given any treatment. The expression of nestin/β-catenin protein in the subventricular zone of the ischemic brain was double-stained for immunofluorescence and analyzed by confocal scanning microscopy dynamically at 3 hours, 21 hours, and then on the 3rd, 5th, 7th and 14th day of HBO therapy. The expression of whole cell β-catenin and nuclear β-catenin protein in the left brain were also examined by Western blotting at these 6 time points. Linear correlation was used to analyze the correlation between β-catenin and nestin protein. Results The expression of β-catenin protein in NSCs increased initially at the 21st hour after HBO therapy in the model group and the HBO group as compared with the normal control group.β-catenin protein in the model group reached a higher level, though there was no significant difference between model group and the HBO group. At the 5th day of HBO therapy β-catenin protein in the HBO group had reached a significantly higher level than in the model group. At the 14th day the average expression of β-catenin in the HBO group began to decrease. The expression of nestin protein began to increase 21 hours after HBO therapy began, and it peaked at the 7th day of HBO therapy and then decreased. In the HBO group the increase in nestin protein was linearly correlated with that of β-catenin protein. The whole cell β-catenin protein and β-catenin nucleic protein readings increased initially by the 21st hour of HBO therapy and by the 5th day were significantly higher than the levels in the model group. Conclusion HBO treatment is capable of stimulating the proliferation of NSCs in HIBD neonate rats.The proliferation of NSCs is correlated with the activation of β-catenin protein.

Objective:To investigate the expression and clinical significance of PD-L1 in colorectal cancer (CRC). Methods:A total of 210 CRC patients who accepted radical surgery in our hospital from January 2015 to January 2016 were divided into three groups, namely, high-frequency microsatellite instability (MSI-H), low-frequency microsatellite instability (MSI-L), and microsatellite stable (MSS). The expression of PD-L1 was detected by immunohistochemistry, and the expression characteristics of PD-L1 in different types of CRC were analyzed. Results:CRC cases with low differentiation had a higher expression of PD-L1 than CRC patients with high differ-entiation (P<0.05). PD-L1 had a positive rate of 75.8%in the MSI-H group and a rate of 9.3%in the MSI-L and MSS groups, wherein the difference between the two groups was statistically significant (P<0.05). Conclusion:PD-L1 was positively expressed in some CRC tu-mor tissues, and its positive rate was significantly higher in MSI-H than in MSI-L and MSS. The therapeutic effect of a PD-L1 blocker for patients with MSI-H CRC might be preferable.

Objective To explore the role of Kupffer cells in high fat diet induced hepatic insulin resistance. Meth-ods Eighty-four C57BL/6J mice were divided into two groups: normal chow (NC) group (7 subgroups) and high fat diet (HFD) group (7 subgroups). Glucose tolerance tests were performed at feeding time of 1,2,4,8,12 and 16 weeks in one NC group and one HFD group. The mice livers at the same feeding time were obtained in other 6 NC groups and 6 HFD groups respectively. The expression levels of IRS1-ser307, Akt-ser473, S6K1-thr389 and p-JNK were detected by Western blot as-say. The values of MCP-1,TNF-α,IL-1βand IL-10 mRNA were examined by qRT-PCR. Results Compared with NC group, the impaired glucose tolerance was found from the first week in HFD group (P ＜ 0.05). The hepatic expressions of IRS1-ser307, S6K1-thr389 (4-16 weeks ) and p-JNK(2-16 weeks ) increased and Akt-ser473(8-16 weeks )decreased in HFD group than those of NC group. The same results were gained by analysis of protein relative expression (all P＜0.05). The hepatic pro-inflammatory factor MCP-1,TNF-αand IL-1βmRNA expressions were higher in HFD group than those in NC group during 2-16 weeks (all P ＜ 0.01). The anti-inflammatory factor IL-10 mRNA was significantly lower in HFD group than that in NC group during 4-16 weeks (all P＜0.01). Conclusion High fat diet maybe play a role in the hepatic insulin resistance by stimulating M1 Kupffer cells to secrete pro-inflammatory factor and inhibiting M2 Kupffer cells to se-crete anti-inflammatory factor.

Objectives To study the prevailing status of coal-burning type endemic fluorosis in Fuyuan County of Yunnan Province, and to provide a scientific basis for fluorosis control and prevention. Methods In 2013, five towns were selected from the villages and towns which the defluoridation stove project was implemented and by the end of 2007 defluoridation stove rate was higher than 95%(including 95%), and two natural villages were selected in each township to carry out the investigation. Dental fluorosis was examined of all children aged 8 to 12 of survey points. At least 20 people were selected in each village. At the same time, 20 copies of instant urine samples were collected from these children of half male and half female, and urinary fluoride was determined. Then five natural villages were sampled from all survey points, and permanent residents were divided into25-,35-,45-,55-and≥65groups according to age. Six people were selected from each group with male and female in half who were conducted examination of adult skeletal fluorosis by X-ray. Dental fluorosis diagnosis was based on theDental Fluorosis Diagnosis(WS/T 208-2011). Urinary fluoride determination was done in accordance withUrine-Determination of Fluoride-Ion Specific Electrode Method(WS/T 30-1996). Skeletal fluorosis diagnosis was carried out according to Diagnostic Criteria for Endemic Skeletal Fluorosis (WS 192-2008). Results A total of 556 children aged 8 to 12 were monitored, the detection rate of dental fluorosis was 41.55%(231/556), the dental fluorosis index was 0.78. The very mild, mild, moderate and severe proportions of children's dental fluorosis were 20.50%(114/556), 17.09%(95/556), 3.60%(20/556) and 0.36%(2/556), respectively, given priority to very mild. The prevalence of dental fluorosis in children was increased with increasing age (χ2=74.27, P<0.05). One hundred and ninety-three copies of child urine samples were tested, the geometric mean of urinary fluoride was 0.62 mg/L, and the urinary fluoride contents were between 0.10-2.93 mg/L. A total of 116 adults were examined, and the detection rate of skeletal fluorosis was 9.48%(11/116). Detected cases of skeletal fluorosis was given priority to mild (9 cases, accounted for 81.81%), more men cases [16.36% (9/55)] than those of women [3.28% (2/61), χ2 = 5.77, P< 0.05]. Conclusion The hazard of coal-burning type fluorosis has been reduced in Fuyuan County , the affect of defluoridation stove project is obvious.

Objective To analyze the expression of TBX1 gene in kidney tissues in patients with clear cell renal cell carcinoma(ccRCC)and in?vestigate its molecular genetics mechanism during the tumor development. Methods Real?time quantitative polymerase chain reaction(qRT?PCR)was used to detect the expression of TBX1 mRNA in 12 cases of clear cell renal cell carcinoma tissues and the corresponding normal kidney tissues adjacent to carcinoma .The protein expression of TBX1 was assayed by Western blot in both groups. Results Both TBX1 mRNA level and the protein level were significantly up?regulated in ccRCC tissues compare to those in normal kidney tissues adjacent to carcinoma(all P<0.05).

Objective To explore the expression and clinical significance of proliferation associated antigen Ki-67 in acute myeloid leukemia (AML). Methods A total of 45 AML patients (including 36 newly diagnosed AML patients and 9 recurrent AML patients) and 20 healthy volunteers (healthy group) were enrolled from October 2012 to January 2016 in Department of Hematology in Fuxing Hospital. The expression of Ki-67 in bone marrow blast cells were detected by flow cytometry (FCM). The relation between Ki-67 level and clinical characteristics, and the prognostic significance of Ki-67 were studied. Results The positive rate of Ki-67 in newly diagnosed AML, recurrent AML patients and healthy controls were (10.38±8.41)%, (20.99± 11.49) % and (40.77±11.97) %, respectively. The positive rate of Ki-67 in newly diagnosed AML patients or recurrent AML patients were significantly lower than that in healthy controls (all P<0.05). The positive rate of Ki-67 in newly diagnosed AML patients was significantly lower than that in recurrent AML patients (P=0.006). The level of Ki-67 in newly diagnosed AML patients did not significantly correlated with age, FAB subtype, white blood cell count, a history of myelodysplastic syndrome (MDS), level of lactate dehydrogenase (LDH), proportion of blats cells, NPM1 gene mutation, FLT3-internal tandem duplication (ITD) gene mutation, chromosome karyotype and response to induction therapy (all P>0.05). There was no significant difference of overall survival between high Ki-67 expression group and low Ki-67 expression group in newly diagnosed AML patients [(780±110) d vs. (788±118) d, P=0.927]. Conclusions The proliferation of blast cells in AML patients is lower than that in healthy controls. Detecting the level of Ki-67 may provide a reference for choosing the cell cycle specific chemotherapy drugs in clinical practice. Monitoring Ki-67 during AML process contributes to monitoring disease progression and predicting recurrence.

OBJECTIVE: To compare and analysis outcomes of different age paragraph hearing aid users by questionnaires. METHOD: The questionnaire was deployed to 90 hearing aid users, 40 females and 50 males, with ages between 19 and 80 years-from junior high school education to university education, suffering binaural severe or moderate sensorineural deafness. The subjects were devided into 3 groups, the A group with ages between 19 and 40 years, the B group with ages between 41 and 60 years, the C group with ages between 61 and 80 years. After being fitted with hearing aids for 6 weeks, 6 months and 12 months, SADL and IOI-HA were applied to evaluating 90 subjects. The study was carried out through face to face interview or by telephone. RESULT: There were significant differences in SADL scores of positive effect, service and Personal image among the 3 groups (P < 0.01). The scores of the A group was the highest, and the B group was higher than the C group. On the contrary, there were significant differences in SADL scores of negative effect among the 3 groups (P < 0.01), with the scores of the A group being the lowest, and the B group being lower than the C group. There were also significant differences in IOI-HA scores among the 3 groups (P < 0.01). The scores of the A group was the highest, and the B group was higher than the C group. CONCLUSION The outcome and satisfaction of hearing aids among different age paragraph is improved with the wearing time growth, but the outcome and satisfaction of hearing aids are decreased with the age growth.
