Objective The aim of the study is to explore the sexual life situation of adult males with continuous ambulatory peritoneal dialysis (CAPD).Methods Data of experience about sexual life of 12 male CAPD patients was collected using in-depth interview and were analyzed with category approach.Results Five themes were sublimated:declined sexual desire,decreased self-confidence to get and to maintain an erection,restraint of sexual life,changes in sexual and marriage satisfaction,and urgent desire for sexual knowledge.Conclusions There are varying degrees of sexual dysfunction in adult male CAPD patients.Nurses should pay attention to and supply the education of sexual knowledge.

Objective To explore factors affecting long-term compliance to weight management (WM) of patients with congestive heart failure (CHF)and to provide evidence for improving patients' compliance.Methods In-depth semi-structured interviews based on reinforcement theory were conducted among 18 CHF patients who received WM intervention over 6 months.The data were analyzed by Colaizzi analysis program.Results Three themes were found:precipitating factors such as the correct perception of disease and self-efficacy,the factors of positive reinforcement such as early gains from WM,readmission,follow-up,family and social support,as well as the factors of negative reinforcement such as gaining nothing during long period,physical and mental disorders.These above factors made long-term compliance to WM of 50％ of the participants dynamic and fluctuant.Conclusions Medical staff should identify patients'compliance at different stages in time during follow-up,analyze the factors that affect their compliance,and then grasp the optimal timing of intervention to perform targeted,multiform and multiple health education to improve compliance.

Objective:To observe and analyze the clinical features and prognosis of proliferative diabetic retinopathy (PDR) with chronic myeloid leukemia.Methods:A retrospective case series study. From May 2011 to December 2020, 5 patients (10 eyes) were included in this study in Eye-ENT Hospital of Fudan University. Basic information about the patient's age, gender, diabetes history and CML history were collected. The endocrine and hematological indexes of all patients were evaluated. All the patients were undertaken visual acuity, intraocular pressure, slit lamp and fundus examination and other examinations to observe the eye conditions. Ophthalmic treatments included panretinal laser photocoagulation, intravitreal injection of anti-vascular endothelial growth factor, vitrectomy. During the follow up period from 5 months to 6 years, prognosis was observed at each office visit. During the follow up period, patients' vision, intraocular pressure, anterior segment and retinal status were observed.Results:There were 4 males and a female in 5 patients. The ages were from 27 to 49 years, with the mean age of 39 years. All patients were bilateral. All patients suffered type 2 diabetes for 3 months to 13 years. Four of them were diagnosed as chronic myeloid leukemia before visiting to ophthalmologists, while the other visited to ophthalmology first due to poor vision. The initial visual acuity ranged from light perception to 0.4 and 6 eyes were less than 0.1. In addition to the typical manifestations of diabetic retinopathy, such as venous tortuous dilation, exudation, microaneurysm and neovascularization, patients also presented with Roth spot as leukemic fundus manifestations. All eyes developed to PDR stage. Abnormal thickening of the neovascular membranes may occur in the lower part of the retina, with secondary traction retinal detachment. All the eyes were treated with pan retinal photocoagulation and 9 eyes underwent pars plana vitrectomy. After treatment, retina of 8 eyes kept flat. The best corrected visual acuity ranged from no light perception to 1.0, and only 4 eyes reached more than 0.2. Unfortunately, one eye lost vision because of secondary neovascular glaucoma.Conclusions:PDR patients with CMLof fundus not only have venous tortuous dilation, exudation, microaneurysm and neovascularization, also present with Roth spot as leukemic fundus manifestations. Diabetic retinopathy combined with CML could progress rapidly, and its aggravating complications such as hyperplastic membrane, vitreous hemorrhage and traction retinal detachment may result in poor visual prognosis. Early screening and treatment can help improve the prognosis of patients.

In this study, a composite cell model for evaluation of idiosyncratic drug-induced liver injury (IDILI) was established in vitro from the perspective of immune inflammation. And this model was used to evaluate the risk of IDILI for 2,3,5,4'-tetrahydroxy-cis-stilbene-2-O-β-glucoside (Cis-SG) and 2,3,5,4'-tetrahydroxy-trans-stilbene-2-O-β-glucoside (Trans-SG). To determine the low, medium, and high dosage of Cis-SG and Trans-SG, CellTiter-Glo^® 3D Cell Viability Assay was used to detect the effects of Cis-SG and Trans-SG on cell viability of HepG2 cells in three dimensional (3D) culture, and MTT assay was used to detect the effects of Cis-SG and Trans-SG on cell viability of THP-1 derived macrophages. THP-1 derived macrophages were incubated by Cis-SG and Trans-SG directly or supernatants from HepG2 cells incubated with them. Enzyme linked immunosorbent assay (ELISA) was used to detect the levels of interleukin-1β (IL-1β) in the supernatants of the THP-1 derived macrophages. Western blot and reverse transcription-polymerase chain reaction (RT-PCR) were used to determine the expression of apoptosis-associated speck-like protein (ASC), Nod-like receptor protein 3 (NLRP3), cysteinyl aspartate specific proteinase-1 (caspase-1), and IL-1β in THP-1 derived macrophages. The results showed that there was no effect on the secretion of IL-1β in THP-1 derived macrophages incubated by Cis-SG and Trans-SG directly. However, the secretion of IL-1β, the protein and mRNA expression of ASC, NLRP3, caspase-1, and IL-1β significantly increased in THP-1 derived macrophages incubated by supernatants from HepG2 cells incubated with 1, 5, and 25 μmol·L^-1 Cis-SG or 25 μmol·L^-1 Trans-SG. In summary, the composite cell model for evaluation of IDILI established in vitro has been successfully applied in testing Cis-SG and Trans-SG. This composite cell model is helpful to evaluate and screen drugs with IDILI risk in vitro preliminarily, which provides methods for predicting and solving the idiosyncratic liver toxicity of drugs.

OBJECTIVETo investigate the effects of free and pedicled thoracodorsal artery perforator (TDAP) flaps for repairing skin and soft tissue defects in limbs, neck, axillary and shoulder.

METHODSFrom October 2009 to Auguest 2011, 16 TDAP flaps were used to repair skin and tissue defects. Among them, five ipsilateral pedicled flaps were used to repair wounds in neck, axillary and shoulder. 11 free TDAP flaps were used to repair the wounds with bone or tendon exposure. In 12 cases, the flaps were pedicled with thoracodorsal artery and vein-lateral branches-perforators, in 4 cases, pedicled with thoracodorsal artery and vein-serratus anterior muscular branches-perforators. The deep fascia, the latissimus dorsi and thoracodorsal nerve were not included in all flaps. The flaps size ranged from 10 cm x 5 cm to 26 cm x 10 cm.

RESULTSAll 16 flaps survived completely with primary healing both at donor site and recipent area. After a follow-up of 3 to 24 months, all flaps gained good texture and appearance. Only linear scar was left at donor area. The shoulder could move freely.

CONCLUSIONSTDAP flap has good texture, long vascular pedicle,and reliable blood supply, leaving less morbidity at donor site. The latissimus dorsi and thoracodorsal nerve are also preserved. The pedicled TDAP flap is an ideal flap for repairing the ipsilateral skin and soft tissue defects of the neck, shoulder, axillary. The free TDAP flap is suited for repairing skin and soft tissue defects of the extremities.

Objective To study experimentally the mechanism of Guasha therapy in curing diseases. Methods All Wistar rats (n=40) were randomly divided into the normal group, group with 0.5 hour after Guasha (0.5 h group), group with 6 hours after Guasha (6 h group) and group with 12 hours after Guasha (12 h group). The arterial blood samples were collected and given blood routine examination. The levels of bilirubin, superoxide dismutase (SOD), interlukin- 1 (IL-1) and IL-6 were detected respectively . Results In the 6 h group the WBC count decreased significantly and the level of the total bilirubin increased significantly (P<0.05) compared with those in the normal group. The level of SOD decreased significantly in the 12 h group compared with that in the normal group (P<0.05).[WTHZ] Conclusion The Guasha therapy can inhibit the inflammatory reaction of WBC and raise the level of the total bilirubin , which may be its one of the mechanisms for abating of fever and curing diseases.

OBJECTIVETo realize quadratic formula optimization of Renshen Jianxin Capsule (RJC) by screening Chinese herbs with major anti-myocardial ischemia effect in RJC and optimize their optimal dosages.

METHODSBy following "uniform design-pharmacodynamic experiment-mathematical modeling-formula optimization", authors employed U10(10(8)) uniform design in the experiment. Eight Chinese herbs contained in RJC were taken as observatory factors. Electrocardiograph (ECG) changes of myocardial ischemia induced by isoproterenol were taken as pharmacodynamic indices. The mathematical model between herbal factors and pharmacodynamic indices was established using stepwise regression analysis to screen Chinese herbs with major anti-myocardial ischemia effect. Their optimal dosages were optimized using the grid algorithm.

RESULTSThe regression equation was y =1. 7889 -0. 3247 Ginseng xSalvia Miltiorrhiza -0. 0663 Astragalus membranaceus xOriental Waterplantain tuber. Forecasting factors included were Ginseng, Salvia Miltiorrhiza, Astragalus membranaceus, and Oriental Waterplantain tuber. The optimal formula dosage calculated by the grid algorithm was Ginseng 1. 62 g, Astragalus membranaceus 4. 62 g, Salvia Miltiorrhiza 2. 43 g, and Oriental Waterplantain tuber 1. 66 g.

CONCLUSIONUniform design combined with stepwise regression analysis and grid algorithm were able to realize quadratic formula optimization of RJC.

OBJECTIVEGene sequence data were clustered to explore evolution lineages of H3 antigen of influenza A virus.

METHODSAll data of H3 RNA sequence in NCBI Genbank and Influenza sequence database were downloaded and aligned in ClustalX while two step cluster method were applied to explore the data.

RESULTSAll sequences were aggregated into ten clusters, while seven of them mainly were human virus. Human virus and avian/other mammal virus were separated into different clusters distinctively, but coexisted into same clusters with swine virus. Time and host distribution were very distinctive in these clusters, but no geographic distribution features were found.

CONCLUSIONWith the interaction of human immunity system, H3 antigen mutated significantly every 5 - 7 years, and the speed of mutation had accelerated with the application of influenza vaccines in recent years. Mean while, human and swine influenza virus were not separated distinctly between clusters indicating that they had short inheritance distance. Result showed again that swine served as the mixer for antigenic recombination of different influenza virus.

OBJECTIVETo study the expression levels of monokine induced by interferon-gama; (Mig) mRNA and its association with HBV DNA and alanine aminotransferase (ALT) in patients with chronic hepatitis B.

METHODSThe level of Mig mRNA in peripheral blood mononuclear cells (PBMCs) was dynamically detected with real-time quantitative PCR, and the ratio of chemokine/GAPDH was considered to represent the final chemokine level. The plasma level of was measured by enzyme-linked immunosorbent assay (ELISA).

RESULTSThe mean level of Mig mRNA in PBMCs of the patients with chronic hepatitis B was 0.6883-/+0.0693, which was significantly higher than that in normal controls (P<0.001). The plasma Mig level in the patients was 609.6-/+73.8 pg/ml, also significantly higher than that in normal controls (P<0.05). In patients with chronic hepatitis B, the level of Mig mRNA in the PBMCs was significantly correlated with plasma Mig level (r=0.7157, P<0.001), and plasma Mig level was correlated with plasma ALT level (r=0.7220, P<0.001) and plasma HBV DNA level (r=0.7266, P<0.001).

CONCLUSIONBoth the expression of Mig mRNA in PBMCs and plasma Mig concentration are elevated in patients with chronic hepatitis B. Mig plays an important role in migration of the inflammatory cells to the liver and mediates the development of chronic hepatitis B.

OBJECTIVETo investigate the expression of B lymphocyte stimulator (BlyS) and its receptors in multiple myeloma (MM) cells, and to explore the relationship between BLyS and the development of human multiple myeloma.

METHODSFlow cytometry, RT-PCR and Western blot were used to examine the expression of BLyS and its receptors in MM (KM3 and CZ1) cells. Fluorescence immunocytochemical method and confocal laser scanning technique were applied to the localization of BLyS in KM3 cell. WST proliferation assay was used to examine the effect of BLyS on MM cells growth and survival. Linear correlation analysis was used to detect LDH and beta 2-microglobulin (beta2M) levels with BLyS protein and mRNA expressions in MM patients.

RESULTS(1) BLyS and its receptors were expressed in MM cells. (2) BLyS protein was localized on the KM3 plasma membrane. (3) BLyS promoted survival and proliferation of MM cells. (4) MM patients had significantly higher expression levels of BLyS [77.42% (24/31)] BLyS mRNA [93.55% (29/31)], which were significantly correlated with the levels of LDH and beta 2-microglobulin (beta2M).

CONCLUSIONBLyS and its receptors in MM cell lines and MM patient bone marrow might have a potential role in the growth and survival of malignant plasma cells.
