Objective To analyze the relationship between insulin resistance (IR) and left ventricular hypertrophy ( LVH ) in patients with early chronic kidney disease ( CKD ). Methods Homeostatic model method was used for detecting insulin resistance index (Homa-IR) in 108 patients with early CKD and 25 normal healthy cases, and the other clinical data such as Hb, creatinine clearance rate (Ccr) , parathyroid hormone (PTH) , ambulatory blood pressure monitoring ( ABPM ) data, including day average systolic blood pressure (dSBP), day average diastolic blood pressure (dDBP), night average systolic blood pressure ( nSBP) , night average diastolic blood pressure ( nDBP) , 24-hour mean systolic blood pressure (mSBP), 24-hour mean diastolic blood pressure (mDBP), decline in the percentage of diastolic blood pressure at night (nDPD) and decline in the percentage of systolic blood pressure at night (nDPS) were also measured. Echocardiography was used for measuring LVH relevant data, and left ventricular mass index (LVMI) was calculated. Then, the relationship between LVH and IR and other clinical data were analyzed retrospectively. Results IR existed in early CKD patients. With the decline of Ccr, both the value of Homa-IR and the incidence of IR increased significantly (both P < 0. 05). LVH existed in early CKD patients and with the decline of Ccr, both LVMI value and the incidence of LVH increased significantly (both P <0. 01). Compared with the non-IR group, the IR group had higher LVMI value (P<0. 05) and higher incidence of LVH (P<0. 01). Compared with the non-LVH group, the LVH group had higher levels of Fins, 2hPG, Homa-IR (all P <0. 05), and higher incidence of IR (P <0. 01). The LVH group had significant lower levels of Ccr, Hb and nDPD (all P <0. 05) , higher levels of dSBP, dDBP, nSBP, nDBP, mSBP, mDBP and PTH (all P<0.05) than the non-LVH group. LVMI had significant positive correlations with 2hPG, Fins, Homa-IR, dSBP, nSBP, mSBP and PTH (r = 0.255, 0.373, 0.376,0.222,0.199,0.225,0.221,0.246, respectively; all P<0.05), but significant negative correlations with Hb and Ccr (r = -0.588,-0.313, respectively; both P<0.01). Multi-factor regression analysis showed that Hb, Homa-IR, and Ccr entered the regression equation (y = 167. 106 - 0. 755x_1 + 0. 250x_2 +0.322x_3, y = LVMI; 167. 106 = constant, t = 12. 138, P =0.000; x_1 =Hb, t= -6.800, P = 0. 000; x_2 = Homa-IR, t = 3. 229, P = 0. 002; x_3 = Ccr, t = 2. 898, P = 0. 005). Conclusion IR existed in early CKD patients and become more severe with the decline of renal function. IR had a significant correlation with LVH, and it may be an important risk factor for the development of LVH. Besides, both anemia and decline of renal function are also associated with LVH.

Objective To analyze the cases of malignant tumors found in health examination in our hospital, and to determine the prevalence and characteristics of malignant tumor, and to provide evidence for the development of effective early screening program. Methods A total of 468673 subjects were included from those who had health checkup from July 2009 to December 2014 at the physical examination center. The subjects were between 4 to 96 years of age, with average age of (56.0±12.5) years. Of them, there were 278484 men, 190189 women. All cases found in the examination were confirmed with pathological testing. Prevalence comparison was done withχ2 test, statistic significance level was set at P<0.05. Results Totally 753 cases of malignant tumors were found in 6 consecutive years, with an overall prevalence rate at 160.7/100000. The prevalence rate increased yearly from 50.0/100000 for the first year, and 100.6/100000, 146.1/100000, 149.1/100000, 188.9/100000, 221.6/100000 thereafter. The difference between each 2 years was statistically significant (P<0.01). The top ten malignant tumors were liver cancer, cervical cancer, lung cancer, renal cell carcinoma, esophageal cancer, gastric cancer, colon cancer, breast cancer, leukemia and thyroid cancer. The prevalence rates of malignant tumors in the top three were liver cancer, lung cancer and kidney cancer for man and cervical cancer, lung cancer and breast cancer for women respectively. With the increase of age, the incidence of malignant tumor showed a rising trend, especially for the group of over 80 years old. But women with cervical cancer in the 50-years age group was the highest. Conclusion The number of cases of malignant tumors found in the health checkup population was rising. It is important to include early screening for malignant tumor in physical examination. We should also pay attention to the relevant departments, in order to improve the early cancer detection rate and decrease the morbidity and mortality of malignant tumors.

Humic acid (HA) was extracted by NaOH solution from black soil of Heilongjiang in China.Reaction characterization of rare earth elements (La3+,Ce3+,Gd3+and Y3+) with HA was studied by Fourier transform infrared (FTIR) spectroscopy.Results showed that peaks (1600 cm-1 and 1400 cm-1) in FTIR spectra of HA became strength after reaction,implying that carboxyl groups of HA reacted with rare earth elements.

Objective To observe the clinical efficacy of stuck-moving needling plus modified Bu Zhong Yi Qi (supplementing qi in the middle energizer) decoction in treating gastroptosis due to qi deficiency in the middle energizer. Method Sixty patients with gastroptosis due to qi deficiency in the middle energizer were randomized into a treatment group and a control group, 30 cases in each group. The treatment group was intervened by stuck-moving needling plus the modified Bu Zhong Yi Qi decoction, while the control group was treated with the modified Bu Zhong Yi Qi decoction alone. The two groups were treated once a day, 20 sessions as a treatment course. The lower limit of the stomach was measured before and after the treatment in the two groups, and the clinical efficacy and long-term efficacy of the two groups were compared.Result The height of the lower limit of stomach was significantly changed after the treatment in both groups (P<0.01), there was a significant difference in comparing the height of the lower limit of stomach between the two groups after the intervention (P<0.01), and there was a significant difference in comparing the change of the height of lower limit of stomach between the two groups (P<0.01). The total effective rate was 93.3% in the treatment group versus 73.3% in the control group, and the between-group difference was statistically significant (P<0.01); the clinical efficacy in the treatment group was statistically different from that in the control group (P<0.05). The long-term total effective rate was 76.7% in the treatment group versus 50.0% in the control group, and the between-group difference was statistically significant (P<0.01); the long-term clinical efficacy in the treatment group was statistically different from that in the control group (P<0.05).Conclusion The stuck-moving needling plus modified Bu Zhong Yi Qi decoction can produce a more significant efficacy than the decoction alone in treatinggastroptosis due to qi deficiency in the middle energizer, and its long-term therapeutic efficacy is also consistent.

BACKGROUND:Artificial cornea titanium scaffold has a higher complication rate in clinical usage; therefore, to seek a kind of artificial corneal scaffold with high biocompatibility is a hot spot.
OBJECTIVE:To explore the biocompatibility of the artificial cornea titanium scaffold with hydroxyapatite surface modification.
METHODS: Twenty-seven New Zealand white rabbits were enroled to make alkali burn models of the right cornea and then randomized into three groups: in experimental group, artificial cornea titanium scaffold with hydroxyapatite surface modification was implanted into the right eye; in control group, artificial cornea titanium scaffold was implanted into the right eye; in blank group, no scaffold was implanted into the right eye. At 2, 4, 16 weeks after implantation, the right corneas were taken out for pathological observation and scanning electron microscope observation.
RESULTS AND CONCLUSION:At 16 weeks after implantation, there was no difference in the number of inflammatory cels and fibroblasts among the three groups. Over time, in the experimental group, the corneal tissues, fibrous tissues and adhered extracelular matrices were increased gradualy. In addition, the experimental group had more adherent corneal tissues, extracelular matrices and better tissue healing than the control and blank groups. These findings indicate that the artificial cornea titanium scaffold with hydroxyapatite surface modification had good biocompatibility that can effectively promote proliferation of corneal cels and corneal vascularization.

Objective To investigate the clinical and pdysomnographic characteristics and related factors of obstructive sleep apnea hypopnea syndrome (OSAHS) in elderly patients. Methods The 163 elderly patients with OSAHS confirmed by polysomnography were classified into obesity group and non-obesity group according to body mass index (BMI). All cases were grouped into mild,moderate and severe groups according to the apnea hypopnea index (AHI) and night SaO2. The 190non-elderly OSAHS patients were as control group at the same time. The clinical and polysomnographic characteristics were recorded and analyzed. Results (1)The proportion of obesity in OSAHS patients was 79. 1%, there was significant difference between the elderly-obesity group and non-elderly-obesity group (70.3% vs. 83.6%, P＜0.05). (2)The proportions of moderate and severe OSAHS patients were lower in elderly group than in non-elderly group. There were significant differences in AHI, the lowest arterial O2 saturation (LSaO2) and % TRT SaO2 ＜90% between the two groups (all P＜0.05). (3)The sleep architecture disturbance was significantly severer in elderly group than in non-elderly group. The percentages of non-rapid eye movementsleep (NREM sleep)stage Ⅲ-Ⅳ sleep were significantly decreased, and the arousal was significantly increased. (4) The syndrome of OSAHS in elderly group was untypical and the clinical complication was increased.Conclusions The elderly OSAHS patients are less severe than non-elderly group, but the elderly patients have worse sleep architecture disturbance and more complications such as hypertension and other cardiovascular diseases.
