Objective The insulin pathways within ovary are in close relationship with female reproductive ability .The arti-cle was to observe the effects of ovarian insulin resistance on ovarian function and the effects of cryptotanshinone (CRY) on ovarian in-sulin resistance. Methods All mice were randomly divided into saline group (isotonic saline), DEX a group (isotonic saline plus DEX), CRY a group(isotonic saline plus DEX plus cryptotanshinone ), 10 in each group.The degree of insulin resistance was tested on each rat, along with the measurement of disintergrations per minute (DPM), ovulation rate and serum hormone level .After 20 fe-male mice were put to death , their ovaries were randomly divided into 4 groups:blank control group ( blank culture solution ) , DEX b group (DEX), CRY b group(DEX plus cryptotanshinone ), and WT group (DEX plus cryptotanshinone plus wortmannin ), 8 in each group. Murine ovaries in each group were cultured in vitro to test the number of ovarian glucose and the serum hormone level . Results After in-
sulin resistance took place in murine ovaries , significant statistical difference was found between DEX a group and saline group as to 2-deoxy-D-[1,2-3H]-glucose, liver, adipose and ovarian tissues (P<0.05).Ovaries in CRY a group increased significantly compared with DEX a group([2805.2 ±921.5]DMP/mg vs [1183.2 ±382.2]DMP/mg, P<0.01 ).Compared with DEX a group(37.5 ± 7.0, 5.0 ±1.8), the ovulation rate and the average corpus luteum in saline group (26.3 ±5.9, 3.5 ±1.6) and CRY group (27.2 ± 6.3,3.8 ±0.9) decreased (P<0.05).In comparison to DEX a group, the estrogen and progestogen levels in saline group and CRY a group decreased significantly(P<0.05).The expression level of AKT2 protein in DEX a group was much lower than that in saline group([0.39 ±0.01] vs [0.77 ±0.03], P<0.05).The glucose uptake in ovarian tissues cultured in vitro in blank control group , DEX b group, CRY b group and WT group was respectively (3447.2 ±1245.2)DMP/mg, (1183.2 ±382.2) DMP/mg, (2805.2 ± 921.5) DMP/mg, and (1364.2 ±292.3) DMP/mg.DEX b group decreased significantly compared with blank control group , DEX b group and WT group decreased significantly in comparison to CRY b group (P<0.05).In comparison to blank control group, the me-dium testosterone level increased and the protesteron level decreased significantly in DEX b group (P<0.05). Conclusion Tradi-tional Chinese medicine cryptotanshinone can relieve ovarian insulin resistance in vitro and in vivo , and it may exert insulin sensitivza-tion through PI3K pathway.

AIM: To examine the relationship between corneal lymphangiogenesis and hemangiogenesis after keratoplasty.METHODS: Nineteen human corneas were obtained from 19 patients undergoing a second corneal transplantation in Zhongshan Ophthalmic Center in 2005. Blood and lymphatic vessels in human transplanted corneas were identified by lymphatic vessel endothelial receptor(LYVE-1) and platelet endothelial cell adhesion modecule-1(PECAM-1) immunohistochemistry, and double enzyme-histochemistry; then the association of corneal blood vessel counting (BVC) with lymphatic vessel counting (LVC) was examined.RESULTS: Corneal hemangiogenesis was present in 12 cases (63%), and lymphangiogenesis occurred in 5 cases (26%) of human transplanted corneas. In addition, corneal lymphangiogenesis was only present in vascularized corneas. LVC was strongly and positively correlated with BVC(r=0.725;P<0.01).CONCLUSION: Corneal lymphangiogenesis develops after keratoplasty, and strongly associates with hemangiogenesis.

BACKGROUND:Vertebroplasty with bone cement injection can achieve a correction of kyphosis, enhancement of vertebral strength, and elimination of vertebral lesions during reduction of the fracture. OBJECTIVE: To analyze the efficacy of vertebroplasty with bone cement injection on osteoporotic vertebral compression fracture. METHODS:Totaly 84 patients with osteoporotic thoracolumbar vertebral compression fractures (T6-L4), 37 males and 47 females, aged 58-80 years, were randomized into two groups: study group undergoing vertebroplasty with bone cement injection and control group subject to bed rest and conservative treatment (functional exercise of the back muscle). Visual analog scale score, Oswestry disability index and vertebral height were detected and compared between the two groups before and after treatment. RESULTS AND CONCLUSION:There was no difference in vertebral height, visual analog scale score and Oswestry disability index between the two groups before treatment. At 3 months after treatment, the vertebral height was (1.653±0.168) cm in the study group and (1.521±0.200) cm in the control group, with a significant difference (P< 0.05). The visual analog scale scores and Oswestry disability index scores in the study group were both lower than those in the control group at 3 months after treatment and at the last folow-up (P < 0.05). After treatment, there were two cases of pressure sores, three cases of deep venous thrombosis, one case of pneumonia and two cases of urinary tract infections in the control group; while only 4 cases developed bone cement leakage in the study group, but with no obvious clinical symptoms. No difference in re-fracture rate occurred between the control group (n=3) and study group (n=4;P > 0.05). These findings suggest that the bone cement injection as vertebral augmentation therapy can rapidly relieve pain, improve patients' quality of life within a short term and restore the vertebral height in patients with osteoporotic vertebral compression fractures.
5.Defining and conceptualizing general practice:The comprehensiveness of primary care
Chinese Journal of Health Policy 2018;11(4):40-44
Comprehensiveness of care is one of the core attributes of primary health care, and it has a great impact on the first diagnosis,accessibility,coordination and continuity to form the primary health care high perform-ance mechanism. Comprehensiveness of care has been playing an increasingly significant role in case when faced with the challenges of the aging of Chinese population,the high prevalence of chronic diseases,and the rapidly rising cost of health care. It is a fundamental problem for researchers,policy makers,and practitioners to clarify the definition of comprehensiveness of primary health care,which is the basis for managing comprehensive services. This article has systematically reviewed the current researches on definitions of comprehensiveness of basic health care, ascertained the key elements of comprehensiveness,and pinpointed the relationship between the dominant and recessive elements. Then,it defined the conception and the boundary of comprehensiveness of care in the context of primary health care,ac-cording to three principles-controllability, exhaustion, and exclusiveness, and finally conceptualized the primary health care comprehensiveness for further study on the operational definition of primary health care attributes.

OBJECTIVETo study the clinical effects of Yupei Qisun Sequential Method (YQSM, by Shen supplementing and Pi invigorating) of Chinese medicine on correlated indices of repeated implantation failure patients in the fresh cycle.
METHODSSixty patients with more than three failure cycles of in virto fertilization and embryo transfer (IVF-ET) or intracytoplasmic sperm injection (ICSI) were recruited. They were assigned to the treatment group (treated by IVF/ICSI and Chinese medicine) and the control group (treated by IVF/ICSI alone), 30 in each group. The total dose of gonadotropin (Gn), the days of controlled ovary hyperstimulation (COH), the thickness of endometrium on the day of embryo transplantation, the number of retrieved oocytes, the fertilization number, the embryo number, the high quality embryo number, the pregnancy rate, and the implantation rate were compared.
RESULTSIn the treatment group the numbers of embryo and high quality embryo were 7.5 +/- 4.9 and 5.1 +/- 3.2 respectively, which were both higher than those of the control group with significant difference (5.1 +/- 3.2, 3.2 +/- 1.8; P < 0.05). No significant difference existed in aspects of the total numbers of Gn, the days of COH, the thickness of endometrium on the day of embryo transplantation, the numbers of retrieved oocytes, the fertilization number, the pregnancy rate, and the implantation rate between the two groups (P > 0.05).
CONCLUSIONYQSM combined with COH could improve the quantity and the quality of embryos, which was promising to increase the accumulative pregnancy rate of RIF patients.

PURPOSE: To determine whether renal injury induced by ischemia-reperfusion (I/R) could be further improved by mesenchymal stem cells (MSCs) modified with survivin. MATERIALS AND METHODS: Lentiviral vectors were used to introduce the survivin gene into MSCs and the MSCs modified with survivin were transplanted into established mice models of renal I/R injury. Seven days later, serum creatinine (Scr) and blood urea nitrogen (BUN) were measured and the survival of MSCs was determined. Hematoxylin and eosin staining was used to assess renal pathological change. The expressions of hepatocyte growth factor (HGF) and basic fibroblast growth factor (bFGF) in kidney tissue were detected by western blot. RESULTS: Mice transplanted with survivin-modified MSCs demonstrated good renal function recovery with Scr and BUN decline close to normal levels and improvement of renal I/R injury repair. Additionally, the survival of transplanted MSCs modified with survivin was enhanced and the expression of HGF and bFGF in kidney tissue was increased. CONCLUSION: Our results demonstrated that MSCs engineered to over-express survivin could enhance their therapeutic effect on renal I/R injury in mice, probably via the improved survival ability of MSCs and increased production of protective cytokines in ischemic tissue.

OBJECTIVETo study the reliability of establishing a neonatal piglet model of multiple organ dysfunction syndrome (MODS) by cecal ligation and puncture (CLP).
METHODSFourteen neonatal piglets were randomly assigned into Experiment group (n=9) and Control group (n=5). MODS model was established in the piglets from the Experiment group by CLP. The Control group underwent a sham-operation. Serum biochemical parameters (ALT, AST, ALB, BUN, Cr, CK-MB and lactic acid), blood platelet counting and blood gas analysis(PaO2 and PaCO2) were tested at 0, 24, 48, 72, 96, and 120 hrs after operation. The histomorphological changes of important vital organs were examined by hematoxylin-eosin staining under a light microscope.
RESULTSThe levels of serum ALT, AST, BUN, Cr, CK-MB and lactic acid in the Experiment group began to increase 24 hrs after operation. Significant differences were observed between the Experiment and the Control group at 48 hrs in ALT (83.0 +/- 9.3 U/L vs 57.8 +/- 15.8 U/L), AST (348.8 +/- 132.9 U/L vs 106.4 +/- 12.5 U/L), BUN (10.5 +/- 2.5 micromol/L vs 4.3 +/- 1.0 micromol/L), Cr (79.2 +/- 9.0 micromol/L vs 53.6 +/- 6.8 micromol/L), CK-MB (5152.0 +/- 1 857.8 U/L vs 1243.0 +/- 354.5 U/L), and lactic acid (12.3 +/- 4.0 mmol/L vs 4.6 +/- 1.5 mmol/L) (P < 0.01). The high levels of the above parameters persisted until 96 hrs after operation in the Experiment group and then decreased but were still higher than those at 0 h after operation. After operation, the blood platelet counting decreased significantly at 96 hrs, and PaO2 decrease and PaCO2 increase were observed at 48 hrs in the Experiment group compared with the Control group. All animals, except one, in the Experiment group died within 120 hrs after operation (with the MODS incidence of 56%), while none died in the Control group. The tissue injuries with different degrees were observed in the lungs, liver, heart, kidneys and gastrointestinal tracts of the Experiment group.
CONCLUSIONSNeonatal piglet MODS model can be established successfully by CLP.
