Objective To investigate the results of follow-up visits of pregnancy course, delivery and infants of women who got clinically pregnant by assisted reproductive technique after gonadotropin-releasing hormone agonist (GnRH-a) added for luteal support, and to analyse the influence of adding GnRH-a in luteal support on the safety of mother and infant. Methods A retrospective analysis was carried out on the medical record from 215 patients who got clinically pregnant after luteal phase long regimen fresh-cycle transfer was operated. According to the differences in luteal support methods, the patients were assigned to Group A (124 patients, progesterone+dydrogesterone group), Group B (91 patients, GnRH-a added group). The patients′ pregnancy course, delivery time, and the growth and development of infants within 1-2 years were followed up. Results (1)There was no obvious difference between Group A and Group B in terms of the abortion ratio during the early pregnancy (8.1%, 12.1%), the rate of abortion villous deformity (50.0%, 9.1%), the rate of heterotopic pregnancy (10.5%, 5.5%) and rate of twin pregnancy (19.4%, 28.6%;all P>0.05).(2)Compared to group A, during the middle and late pregnancy of single or twin pregnancy in Group B , there was no obvious difference in the rate of fetal chromosomal abnormality, organ malformation incidence, late abortion rate and stillbirth rate (all P>0.05).(3)As to childbirth, in the case of twin pregnancy, there was a higher rate of premature delivery (60.0%, 39.1%;P=0.041), as well as rate of lower birth weight of newborn (56.0%, 34.8%; P=0.037) in group B.(4)The statistics on general growth and development as well as infantile common diseases within 2 years after birth indicated that there was no obvious difference between the two groups in single birth and twin birth subgroup (all P>0.05). Conclusion On the basis of controlling of implanted embryos and reducing the occurrence of twins, GnRH-a luteal support maybe relatively safe and effective.

Objective To propose a new suggestion for the clinical downstaging of nasopharyngeal carcinoma (NPC) in the era of intensity-modulated radiotherapy (IMRT) without changing the current T,N,and M staging system.Methods We reviewed the records of 536 NPC patients treated in Sun Yat-Sen University Cancer Center from January 2002 to December 2006.The Kaplan-Meier method was used to calculate the disease-specific survival (DSS) rate,and the log-rank test was used for survival difference analysis.The Cox regression model was used to calculate the hazard ratio (HR) of each subset.ResultsAccording to the 7th edition of UICC/AJCC staging system,the 5-year DSS rates of stage Ⅰ-Ⅲ patients (except T3N2M0) were all more than 85%(P>0.05),those of stage ⅣA and ⅣB patients were 71.8% and 46.2%,respectively (P=0.171),and that of stage ⅠVC patients was only 24.0%.In stage Ⅲ,the 5-year DSS rate of non-T3N2M0 patients (91.5%) was significantly higher than that of T3N2M0 patients (78.6%)(P=0.042),but there was no significant difference in DSS between T3N2M0 patients and stage ⅣA and ⅣB patients.Based on the above results,new stage Ⅰ included T1-3N0-1M0 and T1-2N2M0,new stage Ⅱ included T3N2M0,T4N0-2M0,and TxN3M0,and new stage Ⅲ included TxNxM1.The 5-year DSS rates of new stage Ⅰ,Ⅱ,and Ⅲ patients were 93.3%,72.7%,and 24.0%,respectively (P=0.000).Compared with new stage Ⅰ patients,new stage Ⅱ and Ⅲ patients had HRs of 4.01 and 16.76,respectively,for 5-year DSS.Conclusions In the era of IMRT,the new clinical staging system (stages Ⅰ,Ⅱ,and Ⅲ) helps with prognostic evaluation and clinical treatment.

OBJECTIVETo observe the effect of Qingfei Peiyuan Micro-pill (QPM) on HIV/AIDS patients with pulmonary infection of phlegm heat obstructing lung syndrome (PHOLS).

METHODSTotally 141 HIV/AIDS patients with pulmonary infection of PHOLS were randomly assigned to the treatment group (94 cases) and the control group (47cases). On the basis of Western medicine, patients in the treatment group took QPM. The therapeutic course for all was 28 days. The improvement of symptoms and signs was observed. The body temperature (BT), chest X ray, and white blood cells (WBCs) were detected.

RESULTSThe Chinese medical syndrome score was lower in the treatment group than in the control group at the 7th, 21st, and 28th day of treatment, showing statistical difference (P < 0.05). The efficacy was better in the treatment group than in the control group at the 7th, 21st, and 28th day of treatment, showing statistical difference (P < 0.05). The BT was lower in the treatment group than in the control group on the 7th day. There was no statistical difference in the patient number with normal WBCs on the 7th day (P > 0.05). But there was statistical difference in the patient number with normal WBCs on the 14th, 21st, and 28th day of treatment (P < 0.05). There was no statistical difference in the patient number with normal chest X ray on the 7th and 28th day of treatment (P > 0.05). But there was statistical difference in the patient number with normal chest X ray on the 14th and 21 st day of treatment (P < 0.05).

CONCLUSIONQPM had certain complementary effect on HIV/AIDS patients with pulmonary infection of PHOLS.

To examine the prospective association between higher blood pressure (BP) and risk of type 2 diabetes mellitus (T2DM) in middle-aged and elderly Chinese adults.

A total of 9,642 middle-aged and elderly Chinese adults (≥45 years old; 47.30% men) without diabetes from the China Health and Retirement Longitudinal Study were included for analyses. Participants were categorized into three groups: normal BP, prehypertension, and hypertension, according to the 2010 Chinese Guidelines for the Management of Hypertension. The incidence of T2DM was determined by self-reported physician diagnosis during two follow-up surveys conducted in 2013 to 2014 and 2015 to 2016.

During the 4-year follow-up, 429 participants (4.45%) developed T2DM, including 3.51% of the men and 5.29% of the women. The incidence rates of T2DM were 2.57%, 3.75%, and 6.71% in the normal BP, prehypertension, and hypertension groups, respectively. After adjustment for age, sex, education level, residence, smoking status, alcohol consumption, body mass index, waist circumference, and dyslipidemia, both prehypertension (odds ratio [OR], 1.32; 95% confidence interval [CI], 0.98 to 1.77) and hypertension (OR, 2.02; 95% CI, 1.54 to 2.64) were associated with increased risk of T2DM, compared to those with a normal BP. The ORs associated with T2DM were 1.08 (95% CI, 1.03 to 1.13) for an increase of 10 mm Hg in systolic BP and 1.06 (95% CI, 1.01 to 1.10) for an increase of 5 mm Hg in diastolic BP.

Higher BP is a risk factor for T2DM in middle-aged and elderly Chines. It may be a potential target for diabetes prevention.

With improved overall survival of cervical cancer patients, the importance of the quality of life (QOL) is increasingly recognized. This study was conducted to compare the QOL of women with different stage cervical cancer before and after treatment to facilitate improved cervical cancer prevention and treatment. We used the generic Medical Outcomes Study Short Form-36 (MOS SF-36) to collect QOL information. Based on SF-36, we interviewed cervical cancer patients at West China Second Affiliated Hospital and Sichuan Cancer Hospital between May 2010 and January 2011. A total of 92 patients with precancerous lesions, 93 with early cancer, and 35 with advanced cancer responded to our survey. Average physical component summary (PCS) scores were significantly different between the three groups at every time point (P < 0.05). Average mental component summary (MCS) scores were significantly different between the three groups after treatment (P < 0.05). Average PCS and MCS scores increased gradually from the pretreatment to posttreatment period for patients with precancerous lesions. However, they reached the lowest at 1 month after treatment for patients with early and advanced cancers and rebounded between 1 and 6 months after treatment. Our results indicate that patients with precancerous lesions and early cervical cancer show better overall QOL than do those with advanced cervical cancer. Additionally, patients with early cancer recover more quickly than do those with advanced cancer in terms of both physical and mental functions. Thus, early detection and treatment initiatives may improve the QOL for patients with precancerous lesions and cervical cancer.

Objective A resistin binding peptide (RBP) was selected by phage display in our previous work. Studies had shown that RBP could antagonize the role of resistin on the lipid metabolism and endocrine function of adipose tissue, but whether RBP affects the insulin secretion of pancreatic cells is still unknown. The aim of this study is to assess the effect of RBP on basal insulin secretion in RINm5F insulinoma cells. Methods The cell viability was measured by 3-[4,5-dimethyhhiazol-2-yl]-2,5-diphenyltetra-zolium bromide (MTT) cytotoxicity assay. The supernatants were assayed for insulin content by enzyme linked immunosorbent assay (ELISA). Reverse transcriptase-PCR assay and Western blotting were used to determine the expression of glucose transporter 2 (GLUT2) involved in insulin secretion. Cytosolic Ca2+, the trigger of insulin exocytosis, was analyzed with the fluorescent probe FURA-3/AM. Results RBP did no effect on the cell viability with a concentration of 10-8-10-12mol/L of 2 hours intervention. But it stimulated basal insulin secretion of RINm5F cells, accompanied by up-regulated increased expression of GLUT2 and elevated concentration of cytosolic Ca2+. Conclusion RBP could stimulate basal insulin secretion without affecting the cell viability.

Objective To investigate the effects of sodium butyrate on the activity of RAW264.7 cells and the osteoclast differentiation.Methods The RAW264.7 cells were treated by sodium butyrate at concentrations of 0,0.25,0.50,1.00,2.00,3.00,4.00 and 5.00 mmol/L,with 3 double pores for each concentration.The cytotoxicity of sodium butyrate on RAW264.7 cells was detected by a CCK-8 kit.The effects of sodium butyrate (0,0.25,0.50 and 1.00 mmol/L) on apoptosis of RAW264.7 cells were detected by Hoechst33342 staining.RAW264.7 cells were induced into osteoclasts by osteoclast differentiation factors.The experiment was carried out in 2 groups (n =3).After induced maturation,the experimental group was treated with 1.00 mmol/L sodium butyrate and the control medium was added only with the same volume of solvent.The number of osteoclasts and the area of bone resorption were observed and compared.The differentiation of RAW264.7 cells was detected by tartrate-resistant acid phosphatase (TRAP) staining.Western blotting was used to detect the effects of sodium butyrate (0,0.25,0.50 and 1.00 mmol/L) on NF-κB-related signaling pathway in RAW264.7 cells.Results Compared with the group of 0 mmol/L sodium butyrate,the activity of cells treated with 1.00,2.00,3.00,4.00 and 5.00 mmol/L sodium butyrate for 24 h was significantly decreased (P ＜ 0.05).Treatment with 1.00 mmol/L sodium butyrate for 24 h induced apoptosis.The number of osteoclasts in the control group and the experimental group were 9.33 ± 2.08 and 4.67 ± 1.16,respectively,showing a significant difference between the 2 groups (t =3.395,P =0.027).The percentages of bone resorption area in the control group and the experimental group were 52.43％ ± 5.38％ and 14.28％ ± 2.72％,respectively,also showing a significant difference between the 2 groups (t =10.970,P ＜ 0.001).Western blot results showed that,compared with other concentrations of sodium butyrate,treatment with 1 mmol/L sodium butyrate on RAW264.7 cells for 24 h led to an increase in the expression levels of cytoplasmic p65,B lymphoma-2 associated X protein and cleaved-caspase 3 and the acetylation of Histone H3 but a decrease in the phosphorylation level of α/β subunit of NF-κB kinase.Conclusions With the increased concentration of sodium butyratecan,the activity of NF-κB may be suppressed and the number of apoptotic cells may increase.1.00 mmol/L sodium butyrate can reduce osteoclast formation and bone resorption area.

OBJECTIVETo investigate the level of the serum IL-23 and its correlation with serum biochemical indices of liver function tests and HBV DNA load in patients with chronic severe hepatitis B.

METHODSFifty patients with chronic severe hepatitis B (severe hepatitis group) and 18 healthy controls (control group) were enrolled in the study. The serum IL-23 expression level was detected by ELISA method. The correlation between IL-23 and ALT, AST, TBil, HBV DNA load was analyzed using Pearson's correlation analysis, respectively.

RESULTSSerum IL-23 expression level in severe hepatitis group was significantly higher than that of control group (P < 0.05). Serum IL-23 level was positively correlated with serum ALT, AST, respectively (P < 0.05), but was not correlated with TBil and HBV DNA load, respectively (P > 0.05).

CONCLUSIONSerum IL-23 expression level was increased in patients with chronic severe hepatitis B and was associated with the severe of inflammation. We, therefore, believe that IL-23 might be involved in the pathogenesis of chronic severe hepatitis B.

OBJECTIVETo explore the effects of integrative medicine (IM) rehabilitation protocolon motor function, activity of daily living, and quality of life (QOL) in hemiplegia patients after stroke.

METHODSTotally 120 patients with post-stroke hemiplegia were allocated to four groups using sealed envalope drawing, i.e., the rehabilitation group, the Chinese medical treatment group, the acupuncture group, and the comprehensive rehabilitation group, 30 cases in each group. Based on routine rehabilitative training, patients in the Chinese medical treatment group, the acupuncture group, and the compre-hensive rehabilitation group received standardized treatment based on syndrome typing, Shi's Consciousness-Restoring Resuscitation acupuncture, Chinese herbs + acupuncture comprehensive rehabilitatino protocol, respectively. The treatmet cycle consisted of 4 weeks with 24-week follow-ups. Fugl-Meyer motor assessment (FMA), Modified Barthel Index (MBI), and Stroke-Specific Quality of Life Scale(SS-QQL), and safety assessment were taken as main effect indices before treatment, at week 4 of treatment, at week 12 and 24 of follow-ups, respectively.

RESULTSThere was no statistical difference in FMA score, MBI score, SS-QOL score among the four groups before treatment (P > 0.05). These scores were significantly improved in the four groups at week 4 of treatment, week 12 and 24 of follow-ups, respectively (P < 0.05). Besides, FMA score and SS-QOL score were significantly improved in the comprehensive rehabilitation group at each corresponding time point, as compared with other treatment groups (P < 0.05).

CONCLUSIONSThe comprehensive protocol could significantly improve motor function, activity of daily living in hemiplegia patients after stroke, and further improve their QOL. Its effect was better than other single treatment.

OBJECTIVETo investigate the application of double-step distraction osteogenesis in the reconstruction of mandibular segmental defects after tumor resection.

METHODSFrom January 2002 to December 2006, six cases of post-tumor unilateral mandibular segmental defects were reconstructed using distraction osteogenesis. The mandibular body was lengthened first, following by mandibular ramus distraction.

RESULTSNo infection or other complication was observed. The maximal distraction length reached 55 millimeter in the mandibular body, and 42 millimeter in the mandibular ramus. The average distraction length was 52 millimeter in the mandibular body, and 34 millimeter in the mandibular ramus. Both the aesthetic and functional result was excellent in all cases.

CONCLUSIONSDouble-step distraction osteogenesis is effective and easily performed in the reconstruction of unilateral mandibular segmental defects with less morbidities and complications. There is no need for donor site. However, the treatment period is relatively long with three staged operations.
