Objective: To study the dissolution characteristics of Qishe Pills in two kinds of media and to lay the foundation for the establishment of quality evaluation methods by stripping method. Methods: With 1% Polysorbate 80 solution and 0.5% sodium dodecyl sulfate (SDS) as media, the sinomenine, calycosin-7-glucoside, senkyunolide I, ononin, calycosin, formononetin, and senkyunolide A, determined by HPLC, were used as indexes. The cumulative dissolution of Qishe Pills at different time was investigated, and the dissolvable situation of respective components in the different media was compared simultaneously. The dissolution models were fit and the dissolution parameters were obtained. Results: The linear ranges of sinomenine, calycosin-7-glucoside, senkyunolide I, ononin, calycosin, formononetin, and senkyunolide A were 0.718-10.770, 0.190-2.850, 0.100-1.500 μg, 31.4-471.0, 34.0-510.0, 33.6-504.0, and 40.0-600.0 ng. In 45 min, the cumulative dissolving rates of the respective components were above 90% (calycosin-7-glucoside excepted) with 1% Polysorbate 80 solution as medium, while they were slower with 0.5% SDS as medium. The Weibull model of the seven components was good in the two kinds of media, while other model of the individual components had higher correlation in the different media. The f2 similarity factor method indicated that the dissolution of the same component of Qishe Pills has no similarity in the two different media. Conclusion: The dissolvable speed of each component with 1% Polysorbate 80 as medium was faster than that with 0.5% SDS as medium obviously. With 1% Polysorbate 80 as medium, the dissolution of each component had similarity and synchronism. Using 1% Polysorbate 80 solution as medium is applicable to research the dissolution of Qishe Pills.

AIM: To analyze the electronic product use time, writing time, playing piano time and outdoor activity time and the distribution of myopia in 586 cases of school age children in our hospital. ·METHODS: A retrospective analysis of 586 cases of children aged 6 to 12 years old in the outpatient department was established. Personalized files were used to record the uncorrected visual acuity, optometry, slit lamp, fundus mirror and strabismus. The cumulative use time of electronic products ( including computer, mobile phone, iPad) , writing time, whether to play the piano and outdoor activities time with the eye situation were recorded. Statistical analysis of the age group of myopia, the cumulative use of electronic age in different age groups, writing time, whether playing piano and outdoor activities and the distribution of myopia occurred. · RESULTS: ( 1 ) With the increasing of age, the distribution of uncorrected eyesight was in children mostly mild myopia, and the proportion of mild myopia was significantly higher than that of moderate and high myopia. ( 2 ) Electronic products use time distribution:the proportion of playing electronic products ( including mobilephone, computers, iPad) accounted for 76. 8%, of which 9 years old, 10 years old the cumulative use of electronic products with a long time was higher than other age groups. ( 3 ) Distribution of writing time: the proportion of write homework ≤1h was significantly lower than the proportion of writing homework > 1h (37. 2% vs 62. 8%), of which 9 and 10 years old children cumulative write time was higher than other age group. ( 4 ) Distribution of playing the piano: the proportion of playing piano time less than 1h was significantly higher than the proportion of playing piano time more than 1h ( 89. 1% vs 10. 9%). ( 5 ) Distribution of outdoor activities: the proportion of outdoor activities ≤1h in children at school age was significantly higher than that of outdoor activities > 1h (91. 8% vs 8. 9%). ·CONCLUSION: With the age exposure to electronic products becoming younger, heavy learning tasks and less outdoor activities, myopia occurred in advance of age. So health examination and eye guidance, reducing the amount of work appropriately, increasing outdoor activities will slow the development of early childhood myopia.

Objective To observe the expression of survivin and Aurora B in human pancreatic cancer BXPC3 cells after the treatment of sulindac and to explore the potential mechanism. Methods MTr assay was used to determine the effect of sulindac on the proliferation of the BXPC3 cells. RT-PCR was used to detect the expression of mRNA level of survivin and Aurora B, western blot was used to detect protein expression of survivin and Aurora B Thr-232. Cell cycle and apoptosis were detected by flow eytometry (FCM). Results The BXPC3 cells were inhibited by sulindac in a dose and time-dependent manner; the expression of mRNA of survivin and Aurora B were both significantly decreased from 1.5644 and 0.6554 to 0. 4372 and 0.1132 (P< 0.01), the expression of survivin protein and the phosphorylation of Aurora B Thr-232 were also decreased from 1.2735 and 0.4680 to 0.2126 and 0.2546 (P<0.01); the proportion of cells in the G0/G1 phase was increased from (56.65±1.93)% to (70.58±3.21)% (P<0.01). Conclusions Sulindac had inhibitory effects on the growth of BXPC3 cells, the possible mechanism was via decreasing the expression of survivin which depressed the activity of Aurora B, then the CPC was influenced. The most of the cells were blocked in the G0/G1 phase, and the cells' mitosis was inhibited.

OBJECTIVETo study the effect of treatment of renal anemia by combination of Bushen Jianpi Recipe (BJR, a Chinese experience recipe for supplementing Shen and supporting Pi) and low dosage erythropoietin (EPO), and the influence of treatment on change of serum tumor necrosis factor alpha (TNF-alpha) so as to explore the possible mechanism of integrative Chinese and western medicine (ICWM) in treating renal anemia.

METHODSPatients with renal anemia were randomly divided into two groups, the ICWM group and the control group, symptomatic and supporting treatment such as dialysis, supplementing of ferrous, foliac acid and vitamin B12, was given to both groups. Additionally, to the ICWM group, 50 IU/kg of EPO subcutaneous injection for twice every week, and oral intake of BJR, one dose per day taken in two parts, were given, and to the control group, EPO alone, 50 IU/kg by subcutaneous injecting, 3 times per week, was given. The therapeutic course for two groups was 3 months. Blood levels of hemoglobin (Hb), hematocrit (Hct), TNF-alpha were measured before treatment and the therapeutic effect was observed.

RESULTSAfter treatment, the levels of Hb and Hct increased significantly in both groups (P < 0.01), comparison between the two groups in Hb and Hct after being treated for 3 months showed significant difference (P < 0.05). The serum level of TNF-alpha was markedly higher than normal range in both groups before treatment, it significantly lowered after treatment in the ICWM group (P < 0.05), but unchanged in the control group.

CONCLUSIONCombination of BJR and EPO could significantly inhibit the production of TNF-alpha, this may be an important factor for ICWM in effectively improving sensitivity to EPO.

Objective To investigate the correlation factors for hot flashes in climacteric women so as to improve their quality of life. Methods A questionnaire was distributed among 792 climacteric women. The questionnaire items included general information, characteristics of menstruation, reproduction history, information of hot flashes, lifestyle and sexual life. Weight, height, blood pressure, waist and hip circumferences were measured. Logistic regression analysis was made to find out the correlation factors for hot flashes. Results Univariate logistic regression analysis showed that age, education, income, present characteristics of menstruation, dietary habit, soy products intake, physical exercise, satisfaction of sexual life, body mass index (BMI) and systolic blood pressure were significantly associated with hot flashes. Multivariate logistic regression analysis revealed that irregular menstruation or menopause, frequent exercise and higher systolic blood pressure were risk factors for hot flashes in climacteric women. However, higher education, soy products intake and satisfaction of sexual life were protection factors. Conclusion Guiding climacteric women to take moderate physical exercise, knowing more about climacterium, consuming more soy products and controlling diastolic blood pressure are likely to decrease the incidence of hot flashes.

BACKGROUND: Sepsis is a common complication of infections, burns, traumas, surgeries, poisonings, and post-cardiopulmonary resuscitation. The present study aimed to investigate prognostic value of CD4+CD25+ regulatory T cells (Treg) in peripheral blood of patients with sepsis. METHODS: Periphery blood from 28 patients diagnosed with sepsis was collected on day 1 and 7 after hospitalization in the ICU of Shanghai Changzheng Hospital between December 2013 to April 2014. The blood was used for analyses of Treg ratio using flow cytometry and for analyses of blood routine test, C-reactive protein (CRP), bilirubin, procalcitonin (PCT), and coagulation. APACHE II and sequential organ failure assessment (SOFA) scores were also investigated. The results were compared between two outcome groups of survival or death to evaluate prognostic value for sepsis. RESULTS: The patients had an average age of 60.36±15.03 years, APACHE II score 16.68±7.00, and SOFA score 7.18±3.78. Among the 28 patients, 12 had severe trauma (42.9％), 10 had septic shock (35.7％), and 9 (32.2％) died. The median ratio of Tregs was 2.10％ (0.80％, 3.10％) in the survival group vs. 1.80％ (1.15％, 3.65％) in the death group (Z=–0.148, P=0.883) on day 1; however it was significantly changed to 0.90％ (0.30％, 2.80％) vs. 5.70％ (2.60％, 8.30％) (Z=–2.905, P=0.004). CONCLUSION: With better prospects for clinical application, dynamic monitoring of Tregs ratio in peripheral blood has potential value in predicting prognosis of sepsis.

Objective To describe a new kind of Y-shaped metallic stent delivery system and evaluate its feasibility and preliminary effect for managing multiple airway stenoses involving the lower trachea and the tracheal carina.Methods The Y-shaped metallic stent delivery system consisted of three- tier structure.The inner-tier was composed of four parallel guiding tubes,which was used for two guidewires and two threads passing through,the middle-tier was delivery catheter,which contained the four guiding tubes,and the outer-tier was introducer sheath.Under the fluoroscopic guidance,15 patients with multiple stenoses involving the lower trachea and the tracheal carina were treated with the new covered self-expandable Y-shaped metallic stents.Results Stent placement in the tracheo-bronchial tree was technically successful in all patients with obliteration of the dyspnea immediately after stent placement,and SaO_2 was increased form preoperative 75%—89% to postoperative 96%—99%.During follow-up a period of 3—58 weeks (M 22 weeks),all stenosis were resolved without stent-related complications,and the general physical of all 15 patents was improved with no occurrence of obviously dyspnea and bleeding.Karnofsky performance status(KPS)was improved from preoperative 26%—45% to postoperative 72%—95%.Five patients died of the following causes unrelated to stent insertion:multiple organ failure(n=3),cachexia(n=1)and pulmonary infection caused by gastrobronchial fistula(n=1),and the remaining 10 patients were alive with no evidence.of dyspnea at the time of this report.Conclusion Deployment of the covered Y-shaped metallic stent with the use of Y metallic stent delivery system in the management of airway stenoses involving the lower trachea and the tracheal earina was a simple and safe procedure and with a good short-term clinical efficacy.
