Psychological suboptimal health status is an intermediate state between mental health and mental disease.Without timely intervention,psychological suboptimal health may develop into serious diseases that pose a threat to human physical and mental health,such as depression,anxiety disorders and high blood pressure.This review summarizes the scientific concepts,diagnostic Criteria,intervention and pharmacological research of psychological suboptimal health from the perspective of both modern medicine and traditional Chinese medicine and proposes possible solutions to existing problems in order to contribute to the identification,diagnosis,prevention and treatment of psychological suboptimal health.

The most toxic DNA damage is DNA double strand breaks (DSBs), which are mainly repaired by non-homologous end joining (NHEJ). DNA-dependent protein kinase (DNA-PK) belongs to phosphatidylinositol-3-kinase-related protein kinase family (PIKK) and plays a key role in NHEJ. DNA-PK is overexpressed in a variety of cancer cells and is related to the occurrence, development and drug resistance of malignant tumors. In this article, the representative DNA-PK inhibitors with anticancer effects are reviewed, in order to provide a reference to discovery novel DNA-PK inhibitors.

Objective To analyze the risk factors related to survival time of advanced nonsmall cell lung cancer(NSCLC)and to establish a prediction model on survival time. Methods From 2004-2006, 184 patients with advanced NSCLC were enrolled in the Affiliated Hospital to the Nantong Midical College. Related risk factors were analyzed, using the Buckley-James model. Both actual and predicted survival time were compared by log-rank test. Results Through Buckley-James model analysis, data showed that KPS, clinical stage, treatment and pre-treatment hemoglobin were main influencing factors on survival time. Regression equation appeared to be lnMONTH=0.0108 KPS+0.0238 HB+0.4614 Ⅲb+0.8027 Ⅲa+0.3869(radiotherapy+chemotherapy)+0.507 (radiotherapy + operation)+ 0.6082(chemotherapy + operation)- 2.098. There was no statistical difference between the prediction and the actual models of survival time by log-rank test(P=0.575＞0.05). Conclusion KPS, clinical stage, treatment and pre-treatment hemoglobin might be associated. Both the prognosis of patients with advanced NSCLC and the prediction model seemed to have practical significances.

Objective To explore the long-term effect of endemic arsenism on oxidative stress and immune function, and to provide scientific basis for prevention and treatment of the disease in the areas. Methods In 2009, Using cluster sampling and typical investigation, the cross-sectional study was completed. The patient groups and the internal control group were selected in the arsenism areas after 5 years quality improvement of drinking water(Silizhuang village, Daying village and Gucheng village in Shanyin county, Gucheng city, Shanxi province) and they were divided into mild, moderate, severe case and internal control groups, respectively. The external control group was selected in a non-arsenism area(Yangzhuang village in Heshengbu city). The Oxidative stress indicators were determined and analyzed [serum superoxide dismutase (SOD) activity was determined with xanthine oxidase method, glutathione peroxidase(GSH-Px) activity was determined with 2-thio-2-nitrobenzoic acid method, and mmuuity malondisldohyde(MDA) levels was determined with thiobarbituric acid method]. The immune function was determined and analyzed [immunoglobulin G (IgG) was determined with radioimmunoassay method, and serum lysozyme was determined with turbidimetric method]. Results A total of 252 people were surveyed, in which the external control group, the internal control group, mild, moderate and severe patient groups were 56, 57, 49,44 and 46, respectively. Serum SOD activities were (72.19 ± 11.75), (66.96 ± 12.02), (49.79±11.07), (48.54 ±10.56) and (47.68 ± 10.68)kU/L, respectively. The difference of serum SOD activities between the groups was statistically significant(F = 52.42, P ＜ 0.01 ). Serum SOD activities in the external control group were significantly higher than other groups (all P ＜ 0.05). The value in the internal control group was significantly higher than the 3patient groups (all P ＜ 0.05). There were no significant differences between the case groups (P ＞ 0.05). Serum GSH-Px activities of the five groups were (197.41 ± 38.54), (195.02 ± 31.93), (187.26 ± 28.22), (187.24 ± 25.40),(186.88 ± 21.84)U/mg, respectively, and the difference between the groups was not significant(H = 4.21, P ＞0.05). Serum MDA levels of the five groups were (4.51 ± 2.14), (5.88 ± 2.00), (6.44 ± 2.83), (5.89 ± 2.57),(5.88 ± 2.40)μ mol/L, respectively, and the difference between the groups was statistically significant(F = 3.36,P ＜ 0.05). The external control group was significantly lower than other groups(all P ＜ 0.05). No significant difference was observed between other groups(all P ＞ 0.05). Serum IgG levels were(11.16 ± 2.08), (8.15 ± 1.44), (8.77 ±2.54), (9.19 ± 1.97), (8.44 ± 2.52)g/L, respectively, and the difference between the groups was statistically significant(H = 52.92, P ＜ 0.01 ). The external control group was significantly higher than other groups(all P ＜0.05). No significant difference was observed between other groups(all P ＞ 0.05). Serum lysozyme levels were (13.57 ± 5.16), (10.05 ± 3.96), (8.78 ± 3.35), (8.72 ± 3.76), (9.38 ± 4.26)mg/L, respectively, and the difference between the groups was statistically significant (H = 35.00, P ＜ 0.01 ). The external control group was significantly higher than other groups(all P ＜ 0.05). No significant difference was observed between other groups(all P ＞ 0.05). Conclusions The effect of arsenic on the body's oxidative stress response and immune function persists after 5 years of drinking low arsenic water. In addition to intensify arsenic removal from drinking water, it should also strengthen the monitoring of population's health in the diseased areas.

OBJECTIVETo investigate the influence of high oxygen exposure on signaling pathway of the receptor for advanced glycation end products (RAGE)-NF-κB of lung in newborn rats and the mechanisms of protecting lung injury for human mesenchymal stem cells (hMSC).

METHODSTwenty-four newborn Sprague-Dawley rats from three litters were randomly divided into three groups, as hyperoxia exposed + hMSC group (group A), hyperoxia exposed group (group B), and air-exposed group (group C). The rats from the group A and B were placed in a sealed Plexiglas chamber with a minimal in-and outflow, providing six to seven exchanges per hour of the chamber volume and maintaining O(2) levels above 95%, while rats in the group C only exposed to air simultaneously. Seven days later, rats in the group A were injected intravenously with hMSC (5×10(4)) after hyperoxia exposure, but rats in group B and C received subcutaneous injection with PBS alone at the same time point. Then all the rats were exposed to air, and were sacrificed three days later. Immunohistochemistry was used to evaluate the expression of RAGE in lung tissue. The levels of TNF-α and sRAGE in bronchoalveolar lavage fluid (BALF) and in serum were detected by ELASA, RAGE mRNA and NF-κB mRNA in tissue homogenates were detected by RT-PCR, RAGE and NF-κB by Western blotting; also the value of lung damage score were calculated with histology under light microscope.

RESULTSThere were significant differences among three groups in the fields of lung damage score (F = 51.59, P = 0.000), mRNA and protein of RAGE (F = 37.21, P = 0.000; F = 15.88, P = 0.000) and NF-κB (F = 5.695, P = 0.011; F = 4.223, P = 0.0288) in lung tissue homogenates, and the level of TNF-α (F = 38.29, P = 0.000) in BALF, all these parameters in group A and group B were higher than that in group C. While sRAGE in BALF in group A and group B were less than that in group C (F = 4.804, P = 0.0191). There were also significant differences between group A and group B in these parameters (P < 0.05). There were also no significant differences neither in TNF-α nor in sRAGE in serum among three groups.

CONCLUSIONShMSC protects hyperoxia-induced lung injury via downregulating the signaling pathway of RAGE-NF-κB.

Male infertility is a common and complex disease in urology and andrology, and for many years there has been no effective surgical treatment. With the emergence of microsurgery and assisted reproductive medicine (IVF/ICSI), rapid development has been achieved in the treatment of male infertility. The Center for Male Reproductive Medicine and Microsurgery at Weill Cornell Medical College of Cornell University has been playing an important leading role in developing microsurgical techniques for the management of male infertility. The development of microsurgical treatment of male infertility in China has experienced the 3 periods of emerging, making, and boosting ever since its systematic introduction from Weill Cornell Medical College 15 years ago. At present, many Chinese hospitals have adopted microsurgery in the management of male infertility, which has contributed to the initial establishment of a microsurgical treatment system for male infertility in China. However, some deficiencies do exist concerning microsurgical treatment of male infertility, as in normalized technical training programs for competent surgeons, unified criteria for evaluation of surgical outcomes, and detailed postoperative follow-up data. This article presents an overview on the 15-year development of microsurgical management of male infertility in China, points out the existing deficiencies, and offers some propositions for the promotion of its development.

OBJECTIVETo explore the effects of serum glucose and lipids by on chronically lanthanum exposure in rat.

METHODSThe Wistar rats were treated with oral exposure dose 0.1, 2 and 40 mg/kg of lanthanum chloride (LaCl(3)) respectively, after 90 days the rats were sacrificed and the blood was collected for measuring the glycosylated hemoglobin A (HbA1c), the serum was used for measuring glucose, total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) levels.

RESULTSThere were no any differences among the control and 3 dose LaCl(3) exposed rats on the blood HbA1c and serum Glu, TG and LDL-C levels (P > 0.05). The serum TC in 0.1 and 2 mg/kg LaCl(3) dose group rats were (1.38 +/- 0.14) mmol/L and (1.37 +/- 0.26) mmol/L respectively. It was lower than that of the controls (1.57 +/- 0.14) mmol/L significantly (P < 0.05), the serum HDL-C in 0.1 mg/kg dose group rats was (0.79 +/- 0.12) mmol/L and obviously lower than that of control group rats (0.93 +/- 0.10) mmol/L (P < 0.05).

CONCLUSION0.1 - 40 mg/kg LaCl(3) chronically exposed have not greater effect on serum glucose, TG and LDL-C levels in rats, but the lower dose LaCl(3) chronic exposure might cause serum TC and HLD-C level decreasing.
