Objective To explore the expression and significance of phosphatidylinositol-3 kinase (PI3K)in ovarian cancer,and the effect of combined PI3K inhibitor(LY294002)therapy with cisplatin on epithelial ovarian carcinoma,and to explore if there is a synergistic effect between the two therapies. Methods The expression levels of PI3K p85 subunit proteins and mRNA were evaluated by western blot and RT-PCR in normal ovarian tissue(G1),ovarian benign tumor tissue(G2),ovarian borderline tumor tissue(G3)and ovarian cancer tissue(G4),and the relevant clinical pathological parameters were analyzed.SKOV3 ceils were isolated and cultured by enzymolysis method.SKOV3 cells were treated with culture medium only,LY294002(1,10,30,50,100 ?mol/L),cisplatin(0.33,1.25,2.5,5, 10 ?mol/L),LY294002(50 ?mol/L)+cisplatin(10 ?mol/L)for 2 days,respectively.The effect of LY294002 and cisplatin on the growth of SKOV3 cells was measured by methyl thiazolyl tetrazolium assay. Results There was no positive expression of PI3K p85 subunit proteins in G1 and G2,while the expression was 2/6 in G3,and 85%(33/39)in G4.PI3K p85 subunit mRNA expression levels were 0.178?0.102 in G1,0.643?0.112 in G2,0.847?0.058 in G3,1.689?0.423 in G4;there was a significant difference between G1,G2,G3 and G4(P0.05).Significant differences were noted between protein expression levels in G4(Ⅲ,Ⅳ)and G4(Ⅰ,Ⅱ;P

ObjectiveTo explore the effect of peridural injection on acute herniation of intervertebral disc.Methods60 cases of acute herniation of intervertebral disc were divided into two groups,including 30 cases of the peridural injection treatment group and 30 cases of the traditional treatment group. The clinical symptoms and signs were assessed before and after treatment.ResultsThe peridural injection restrained pain rapidly and shorten the period of treatment. The eminent rate was 83.4%. The index and rate in improvement and efficiency of peridural injection group were higher than that of traditional group. The course of treatment in hospital in peridural injection group was shorter than that in traditional group.ConclusionsThe peridural injection has preferable clinical curative effect in herniation of intervertebral disc.

Objective To investigate the clinical prognosis of idiopathic demyelinating optic neuritis (IDON), the rate of its conversion to multiple sclerosis (MS) or neuromyelitis optica (NMO) and its clinical features related to the conversion.Methods Patients satisfying our entry criteria for IDON hospitalized in Beijing Tongren Hospital during the period from 2002 to 2007 were re-evaluated with follow-ups for 6-months to 5-years.The McDonald diagnostic criteria for MS (revised, 2005) was used to diagnose MS in these subjects during follow-up and the diagnosis of NMO utilized 1999 Wingerchuk' s NMO criteria.The Chi-Squared χ2 test was applied to statistically analyze association of clinical features and development of MS or NMO.Results In 107 recruited IDON cases with complete clinical data and follow-up, 12 cases (11.2%) developed into MS or NMO during follow-up period.All 12 cases met the revised McDonald criteria, of which 4 cases met NMO criteria and the remaining eight cases showed some clinical evidence of "optic-spinal MS (OS-MS)".A significantly higher conversion rate of 23.1% was found in recurrent IDON than the 4.4% in single-episode cases (χ2 = 6.899, P < 0.01) .Convesion rate of female patiends (17.2%) is significantly higher than male patients (4.1%, χ2 = 4.620, P < 0.05).Conversion rate of 18.2% in patients with initially abnormal brain MRI was higher than rate of 8.1% in cases with normal brain MRI, but the difference was not statistically significant.No difference was found between presence or absence of swollen disc, nor severity of vision loss.Conclusions In a group of IDON patients, 11.2% developed into MS and NMO or clinically indicative OS-MS.Recurrent IDON and female gender suggested higher risk of developing MS or NMO.

OBJECTIVETo observe the effect of Tai Ji Quan (TJQ) training on strength and function of lower limbs in the aged.

METHODSSixty senile subjects were recruited and assigned to the TJQ group and the control group (imparting health knowledge)by random digit table. Patients in the TJQ group received 24-style TJQ training for 18 months (60 min each time, 5 times per week), while those in the control group were imparted with sarcopenia related causes, pathogeneses, prevention and control measures. The maximum isometric strength of bilateral iliopsoas, quadriceps femoris, tibialis anterior muscle, hamstrings; the time for 5 sitting-up tests and Time Up and Go Test (TUGT), one-leg standing time with closed eyes test; and the score of Berg balance scale were compared between the two groups.

RESULTSCompared with before treatment, muscle strength increased in the TJQ group with an average increased capacity (rate) as follows, bilateral iliopsoas 5.5 kg (16.9%), quadriceps femoris 5.5 kg (26.2%), and tibialis anterior muscle 8.5 kg (36.2%) (all P < 0.05). The time for TUGT and 5 sitting-up tests was shortened by 1.3 s (16.7%) and 0.9 s (14.5%) respectively in the TJQ group. The time for one-leg standing time with closed eyes test was increased by 8.4 s (left) and 9.1 s (right) respectively. The score of Berg balance scale increased by 4.3% (P < 0.05). Compared with the control group, bilateral quadriceps femoris and tibialis anterior muscle strength increased significantly (P < 0.01); the time for TUGT and 5 sitting-up tests, the time for one-leg standing time with closed eyes test, scores of Berg balance scale were all improved in the TJQ group after intervention (P < 0.05).

CONCLUSIONTJQ training could improve strength of iliopsoas, quadriceps femoris, tibialis anterior muscle in the aged, elevate their balance and locomotor activities, and possibly prevent and treat sarcopenia.

Objective To analyze the clinical efficacy of preoperative concurrent radiotherapy and chemo-therapy and radical operation in the treatment of cervical cancer patients with locally advanced cervical cancer (IB -IIB).Methods 80 patients who were diagnosed locally advanced (stage IB -IIB)cervical cancer,were divided into observation group (preoperative radiotherapy and chemotherapy group)and control group (radical radio-therapy group).The short -term efficacy,complications and follow -up data were compared between the two groups. Results The short -term efficacy of the observation group was 87.2%,which of the control group was 95.1%,and there was no significant difference (χ2 =1.579,P =0.209).As to the early complications of the two groups,there were no significant differences in gastrointestinal tract reaction(χ2 =0.000,P =0.987),rectal reaction(χ2 =2.709, P =0.100),bladder reaction (χ2 =1.343,P =0.247)and bone marrow suppression(χ2 =1.898,P =0.168).Late complications:in the observation group,the radiation proctitis[4 cases(10.3%)vs.14 cases(34.1%)]and the radiation cystitis[3 cases(7.7%)vs.13 cases(31.7%)]were less than those of the control group,the differences were statistically significant(χ2 =6.542,P =0.011&χ2 =7.205,P =0.007).The average follow -up time was 38.6 months in the observation group,which was 44.8 months in the control group.There was no significant difference in survival rate between the two groups(χ2 =0.075,P =0.784 & χ2 =0.032,P =0.858).Conclusion Locally advanced cervical cancer (IB -IIB)patients received preoperative concurrent radiotherapy and chemotherapy has important clinical value.The treatment makes the local giant block tumor shrink significantly,which is conducive to the implementation of surgery,and reduce the incidence of late complications compared with radical radiotherapy.

Third-generation aromatase inhibitors (AIs) have been considered as standard adjuvant endocrine therapy for hor-mone-responsive breast cancer in postmenopausal women. Aromatase inhibitor-associated musculoskeletal symptoms (AIMSS) are prevalent among patients undergoing AI therapy;these symptoms result in reduced quality of life and poor dependence to AI treatment. The mechanisms mediating AIMSS and the effective management of AIMSS have not been extensively investigated. This article re-views the incidence, clinical characteristics, possible mechanisms, and treatment of AIMSS.

Objective To analyze the volatile composition in the leaves of Sabina chinensis L. Ant. and Sabina chinensis L. Ant. cv. Kaizuca and to study their effects on bacteria. Methods GC-MS was employed in the analysis of volatile composition and four kinds of bacteria were used for testing the sterilization and bacteriostasis of the volatile oil. Results The main substance in volatile oil from the two kinds of plants, Sabina chinensis L. Ant. and Sabina chinensis L. Ant. cv. Kaizuca, was bornyl acetate and the percentage was 38.1% and 46.5% respectively. In addition, in the volatile oil from Sabina chinensis L. Ant. contained 24% of phellandrne and 12.4% of p-menth-l-en-4-o1, as for Sabina chinensis L. Ant. cv. Kaizuca, 30.0% of limonene and 7.9% of ?-pinene were contained. The volatile oil from Sabina chinensis L. Ant. had greater effects of bacteriostasis and sterilization on Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli compared with Sabina chinensis L. Ant. cv. Kaizuca. Conclusion Compared with Sabina chinensis L. Ant. cv. Kaizuca, the effects of sterilization and bacteriostasis of volatile oil from Sabina chinensis L. Ant. are much greater and with a larger spectrum of bacteria.

Objective To explore the most suitable chemostatic condition and a method of cell-counting in reconstituted basement membrane invasion experiment in vitro. Method Reconstituted basement membrane invasion experiment was employed, and conditioned medium, fibronectin (FN), and a combination of conditioned medium and FN were respectively used as chemoattractants was placed in the lower compartment of the chamber. After the filters were stained with hematoxylin and eosin (HE), two kinds of cell-counting methods were employed. One was random cell-counting to count the cells in 5 fields infiltrated in the different areas of the filter membrane under 40?magnification, and the other was whole cell-counting of the infiltrating cells on the whole filter membrane with 4? magnification and image analysis system. Results The number of infiltrating cells in the presence of the chemoattractants was much larger than that of the control group. The number of infiltrating cells of the conditioned medium group was larger than that of FN group. The numbers of infiltrating cells in the combination of conditioned medium and FN groups were significantly larger than those of conditioned medium and FN alone groups. The accuracy of method of random cell-counting under 40? magnification was poorer than that of whole cell-counting with image analysis system. Conclusion Chemoattractants exert strong effect on the tumor cells invasion, and different chemoattractants show different chemotactic abilities. By using image analysis system to count all the infiltrative cells of the whole filter membrane is an objective and accurate cell-counting method.

AIM:To explore the diagnosis and treatment methods of radioaction-induced optic neuritis ( RION) through the clinical dates of 17 patients.
METHODS: It was a retrospective case series study. From August 2008 to October 2013, 17 cases (24 eyes) of Rion clinical dates from Chinese PLA General Hospital were studied. The diagnosis methods including visual acuity, pupil, fundus, visual field, fundus fluorescein angiography (FFA), visual electrophysiological testing, and head MRI. To analysis the clinical date of patients with diagnosis of RION by statistical description.
