Insulin resistance likely plays a central pathogenic role in polycystic ovary syndrome and may explain the pleiotropie presentation and involvement of multiple organ systems.Hyperinsulinaemia leads to increased production of androgens resulting in anovulatory infertility.Women,especially those obese women with polycystic ovary syndrome,have an increased risk of developing type 2 diabetes and cardiovascular disease in their later life.Treatment of insulin resistance through lifestyle therapy or with a diabetes drug has become mainstream therapy to reduce the risk of diabetes,endometrial abnormalities,and cardiovascular disease events in women with polycystic ovary syndrome.

Oxidative stress is a major contributor to the pathogenesis of diabetes and diabetic complications.Heme oxygenase(HO),an important part of the human defense system,has been recognized to have significant physiological function against oxidative stress.HO can be stimulated by oxidative stress and decompose into carbon monoxide,biliverdin and iron,all with important anti-inflammatory,anti-oxidative stress and anti-apoptosis effects.Overexpression of HO induced by hyperglycemia can protect cells(including islet cells,endothelial cells and monocytes) and tissues from oxidative damage.Increased HO metabolic products not only maintain the physiological function of islet cells, delay diabetes progression,but also regulate vascular,nerve and muscle function,so as to prevent diabetic complications.

OBJECTIVETo investigate clinical effect and safety of bone-setting manipulation in treating isolated systolic hypertension combined with cervical spondylosis.

METHODSFrom January 2012 to January 2015, 320 patients suffered from isolated systolic hypertension combined with cervical spondylosis were randomly divided into treatment group and control group. In treatment group, there were 160 patients including 84 males and 76 females with an average age of (39.82 ± 10.33) years old, average blood pressure was (149.61 ± 10.75)/(81.01± 8.25) mmHg, NPQ score was 24.61 ± 8.14; treated with flexion top spin and lock bone-setting manipulation of cervical spine, once every two days for 20 days. While in control group, there were 160 patients including 90 males and 70 females with an average age of(41.37 ± 9.42) years old, average blood pressure was (151.48 ± 11.32)/ (79.65 ± 9.32) mmHg, NPQ score was 25.78 ± 9.53; treated with manipulation of reposition cervical spine by rotation, once every two days for 20 days. Blood pressure and NPQ score were tested and compared for evaluating clinical effects.

RESULTSBefore and after a period treatment, systolic pressure in treatment group was (149.61 ± 10.75) mmHg and (129.67 ± 12.26) mmHg; (151.48 ± 11.32) mmHg and (132.02 ± 11.73) mmHg in control group. After treatment, systolic pressure in both two groups was obviously decreased, and treatment group was better than control group. Before and after a period treatment, diastolic pressure in treatment group was (80.01 ± 8.25) mmHg and (78.15 ± 10.34) mmHg, (79.65 ± 9.32) mmHg and (76.89 ± 9.79) mmHg in control group, and there was no significant difference between two groups. NPQ score in treatment group was 24.61 ± 8.14 before treatment, 12.46 ± 7.94 after treatment, while in control group was 25.78 ± 9.53, 14.17 ± 8.86; NPQ score of the two groups after treatment was better than before treatment, while there was no obviously significance between two groups after treatment. The whole clinical effect in treatment group was better than control group.

CONCLUSIONBone-setting manipulation for isolated systolic hypertension combined with cervical spondylosis at early stage could receive good clinical result, and flexion top spin and lock bone-setting manipulation of cervical spine was better and safety than manipulation of reposition cervical spine by rotation.

Objective To explore the differences of the life styles and their influencing factors among students who came from city,countryside or migrant families.Methods The stratified cluster random sampling method was conducted to recruit 1980 college students from 4 colleges of Huainan,Anhui.Results The study showed that under the ternary social structure college students from city preferred to the higher degree of T1,T2 or T3 dietary patterns,of which the OR (95％ CI) were 0.432 (0.255-0.730),0.140 (0.073-0.267) and 0.402 (0.236-0.683),respectively.They chose to exercise in middle-intensity physical activity for 30 minutes,of which OR (95％CI) was 0.524(0.352-0.779).Also there were much more drinkers in this group,of which the OR (95％ CI) was 0.564(0.325-0.981).Secondly,college students from migrant families in city preferred to T2 and T4 dietary pattern in low degree,of which OR (95％ CI) were 1.714(1.165-2.519) and 1.592(1.100-2.305),respectively.And they exercise 5 times or less per week in middle-intensity physical activity and the OR (95％ CI) was 0.699(0.535-0.912).Thirdly,college students from countryside preferred to T1,T2 and T3 dietary pattern in low degree and the OR (95％ CI) were 1.548 (1.083-2.213),1.498 (1.048-2.141) and 1.740(1.216-2.491),respectively.However,they preferred T4 dietary pattern in high degree rather than in low degree,in which the OR (95％ CI) was 0.624(0.436-0.893).They exercise more than 5 times and more than 30 minutes per time in middle-intensity physical activity,of which OR (95 ％ CI) were 1.314 (1.022-1.688) and 1.472 (1.071-2.022).Conclusion College students from three groups lived in different life styles and much more attention should be paid to them.

Objective To observe apoptosis of renal development in mouse. Methods Light,electron microscopy and TUNEL method were used. Results The apoptosis could be easily found in cells between S like body in nephrogenic zone and in renal corpuscles before birth, especially at 14 18 days prenatally. The apoptotic cells in epithelia of renal tubule or collecting duct could be observed in postnatal renal medulla. In medullary papilla the cell death peaked around postnatal day 7. Electron microscopy revealed that apoptotic cells were ingested by neighboring cells. Some apoptotic cells detached from epithelia into the lumen of tubule or duct. Conclusion This study provides morphologically some evidences of apoptosis in the mouse kidney embryonically and postnatally. The apoptosis in cortex was apparently related to the development of nephrogenic zone and renal corpuscles; and the apoptosis in medulla might play an important role in the development of renal tubular epithelia.
