Objective: To apply the NRS2002 to screen the nutritional status of preoperative patients and investigate the nutrition support in the perioperation and clinical outcomes. Methods: 127 selective operational cases(including general surgery,thoracic surgery,gynecology and orthopedic) were recruited to adopte the NRS2002 which issued by CESPN in 2006,and the nutrition support,energy and nutriment in the perioperation,complications,length of stay and drug costs were investigated. Result: 30.7% patients needed nutrition support,with general surgery(28.3%) being higher than thoracic surgery(2.4 %),gynecology(0%) and orthopedic(0%).The nutritional risk in elderly,carcinoma,abdominal operation patients were 18.1%,19.7% and 18.1% seperately,which was higher than others(P

Objective To investigate the effect of gravity and lung volume on MR perfusion imaging of human lung using an arterial spin labeling sequence called flow sensitive alternating inversion recovery(FAIR).MethodsMagnetic resonance imaging of lung perfusion was performed in supine position in ten healthy volunteers on a 1.5 T whole body scanner(GE medical system).Five sequentially coronal slices with the gap of 3cm from dorsal to ventral(labeled as P3,P6,P9,P12,P15,respeectivly)were obtained on end respiration and the relative pulmonary blood flow(rPBF)was measured.Another coronal perfusion-weighted image of P3 slice was obtained on end inspiration.Tagging efficiency of pulmonary parenchyma with IR(⊿SI%),the rPBF and area of the P3 slice were analyzed.respectively.Paired Student's t test was used for statistical analysis.Results(1)In the direction of gravity,an increase in rPBF of the gravity-dependent lung was found.rPBF of right lung from dorsal to ventral were 100.57±18.22,79.57±12.36,61.65±11.15,48.92±9.96,41.20±9.88,respectively；and that of left lung were 106.61±26.99,78.89±11.98,64.00±13.64,51.27±8.95,43.04±12.18.No statistical differences between P12 and P15,there were significant statistic differences of any other two coronal planes.But along an isogravitational plane,no statistical difference was observed.Regression coefficients of right and left lung were -4.98 and -5.16,respectively.This means the rPBF of right lung falls by 4.98 for each centimeter above the dorsal and that of left lung falls by 5.16.(2)For(⊿)SI%,rPBF and area,there were significant statistic differences at different respiratory phases(P＜0.05).(⊿)SI%,rPBF,area at expiration phase vs.inspiration phase were 1.12±0.31 vs 0.71±0.18,90.78±17.35 vs 52.85±8.75,(12.59±3.23)×103mm2 vs (17.77±4.24)×103mm2 for right lung;and 1.01±0.24 vs 0.70±0.11,91.08±18.68 vs 54.58±10.70,(12.34±3.08)×103mm2 vs(17.34±4.98)×103mm2 for left lung.Greater (⊿)SI%and increased perfusion were observed on end expiration than on end inspiration.The area was larger on end inspiration than on end expiration.ConclusionsThe FAIR is sensitive to perfusion changes in the gravity-dependent lung.Pulmonary blood flow is less in a state of high lung inflation than in a low state(inspiration vs.expiration).Positioning the patient so that the area of interest is down-gravity and breath-hold on end expiration may improve visibility of perfusion defects.

Objective:To explore the efficacy and safety of 192Ir three-dimensional brachytherapy combined with intensity-modulated radiotherapy in patients with unresectable advanced obstructive extrahepatic cholangiocarcinoma. Methods:A retrospective analysis of the efficacy and safety of 18 patients with unresectable advanced malignant obstructive extrahepatic cholangiocarcinoma admitted to the Cangzhou Hospital of Integrated Traditional Chinese and Western Medicine in Hebei province from January 2014 to January 2018.All patients were pathologically confirmed and received biliary stent implantation, followed by sequential intensity-modulated radiotherapy and 192Ir three-dimensional brachytherapy.The clinical data of all patients were collected, including gender, age, clinical stage, adverse reactions, brachytherapy dose-volume parameters, changes in bilirubin levels before and after treatment, evaluation of efficacy, local control rate and survival rate. Results:All patients successfully completed the treatment.Re-examination was conducted one month after the combined treatment, of the 18 patients, 16 had partial remission (PR) and 2 were stable(SD). Among them, 14 patients had tumor shrinkage after brachytherapy compared with intensity-modulated radiotherapy, and 4 patients showed no significant change.The 6-month local control rate (LC) was 94.4% (17/18). The 1-year survival rate was 55.6% (10/18), and the 2-year survival rate was 38.9% (7/18). Statistical analysis showed that after combined treatment, total bilirubin and direct bilirubin were significantly reduced, and jaundice symptoms were significantly relieved.The adverse reactions of the patient were nausea, vomiting, fever, biliary tract infection, etc.There were no adverse reactions of grade 3 or above.Conclusions:192Ir three-dimensional brachytherapy combined with intensity-modulated radiotherapy in patients with inoperable advanced extrahepatic cholangiocarcinoma has a good local control rate and tolerable adverse reactions, but the impact on long-term survival requires a large sample of controlled studies.

Objective: To observe the difference of the effect of low-frequency electroacupuncture (EA) on blood lipids between male and female patients with simple obesity due to damp induced by spleen deficiency. Methods: Eighty patients with simple obesity were recruited, including 37 males and 43 females, to receive low-frequency EA by selecting Yinlingquan (SP 10), Sanyinjiao (SP 6), Zusanli (ST 36), Fenglong (ST 40), Quchi (LI 11), Tianshu (ST 25), Zhongwan (CV 12), Shuifen (CV 9), Qihai (CV 6) and Guanyuan (CV 4), with needles retained for 30 min. The treatment was given once a day, 10 sessions as a treatment course, for 2 courses in total. The contents of body fat percentage (F%), total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), blood glucose (Glu) and adiponectin (ADPN) in serum were observed to see the changes, and the two groups were compared and analyzed. Results: After the treatment, F%, and serum contents of TC, TG, LDL, Glu and ADPN dropped significantly in the two groups (P<0.05 or P<0.01) and the serum content of HDL increased significantly in male group (P<0.05). The decrease of F% in female group was more significant than that in male group (P<0.01); the decrease of ADPN in male group was more significant than that in female group (P<0.05). Conclusion: EA can regulate the disordered blood lipids in male and female patients with simple obesity, with certain differences between genders. The decrease of subcutaneous fat content is more significant in females than that in males, while the decrease of ADPN is more significant in males.

To design and synthesize the hepatic targeting anticancer prodrug with norcantharidin (NCTD-Gal) conjugating structure, galactosylated NCTD derivatives were synthesized from NCTD analogues modified by a series of amino acids via acylation, hydrolysis, glycosylation and deacetylation. Seven new compounds were synthesized as beta-O-glycosides and characterized by IR, MS, NMR and element analysis. The compound 4a was chosen for the inchoate antitumor experiments on mice. The result showed that the antitumor inhibition rate of 4a groups with medium and high dose are clearly higher than that of NCTD group, which suggests that anticancer effect of NCTD is improved at a certain degree by galactosylation.

OBJECTIVETo compare the clinical effects of circumcision and the foreskin-deglove plus shaft-fix (FDSF) procedure in the treatment of phimosis or redundant prepuce in obese adult males (body mass index [BMI] ≥ 28 kg/m²).

METHODSForty-four obese adult men with phimosis or redundant prepuce underwent circumcision (n = 24) or FDSF (n = 20) according to their own wishes. The patients in the circumcision and FDSF groups were aged (26.38 ± 4.24) and (26.90 ± 3.14) years, with BMIs of (27.77 ± 0.77) and (28.07 ± 2.28) kg/m² and penis lengths of (3.51 ± 0.46) and (3.50 ± 0.59) cm, respectively. The operations were performed under local anesthesia with lidocaine plus ropivacaine mesylate.

RESULTSThe operation time of circumcision was (28.04 ± 2.65) min and that of FDSF was (45.45 ± 3.49) min. At 6 months after surgery, normal penile erection was found in all the patients, the penis length was significantly longer in the FDSF than in the circumcision group ([5.01 ± 0.73] vs [3.70 ± 0.47] cm) , and the rate of satisfaction with penile appearance was markedly higher in the former than in the latter group (3.25 ± 0.71 vs 2.83 ± 0.56).

CONCLUSIONThe foreskin-deglove plus shaft-fix procedure under local anesthesia with lidocaine and ropivacaine mesylate may achieve desirable penile erection and appearance in the treatment of phimosis or redundant prepuce in obese adult patients.

This study aims to construct a eukaryotic expression system for envelope gene of Jaagsiekte sheep retrovirus, observes its localization in 293T cells, and investigates the potential in inducing malignant transformation of NIH3T3 cells. By RT-PCR, the full-length cDNA of envelope gene of Jaagsiekte sheep retrovirus (exJSRV-env) was amplified from the extract of naturally infected sheep lung. The clone of target gene was sub-cloned into eukaryotic expression system pEGFP-C1, and validated by PCR, restriction endonuclease, and sequencing. Bioinformatic analysis concerning biological function and cellular localiza tion of exJSRV-env was also performed. The recombinant clone of exJSRV-env was transfected into 293T cells and NIH3T3 cells by Lipofectamine LTX. The expression and celluar localization in 293T cells were validated by confocal microscopy. Soft agar colony formation assay was employed to test the anchorage-independent growth of NIH3T3. DNA sequencing and restriction enzyme digestion with Kpn I and Hind III indicated the correct construction of the recombinant plasmid, which was named pEGFP-C1/exJSRV-env. Amino acid sequence alignment of exJSRV-env with reference sequences found 85%-100% homogeneity. A YRNM motif was discovered at the cytoplasmic tail of envelope gene, which is exclusively found in exogenous viruses. Phylogenetic tree analysis showed that our clone of exJSRV-env clustered closely with pathogenic exogenous Jaagsiekte sheep retroviruses. Fluorescence microscopy indicated typical membrane localization of exJSRV-env protein. NIH3T3 cells transfected with exJSRV-env lost contact inhibition, and acquired colony forming ability in soft agar. This study indicated that envelope protein of Jaagsiekte sheep retrovirus can induce malignant transformation of mouse fibroblast cell NIH3T3. Discoveries of this study provide a basis for further structural and functional research on Jaagsiekte sheep retrovirus envelope protein.

Objective To investigate the functional changes of dendritic cells (DC) in elderly patients with sepsis. Method Elderly patients (n = 20), ages 75 to 86 years, treated in the department of internal medicine for cadres and the medical intensive care unit (MICU), were selected to participate in the study. Patients with ma-ligoant tumors, hematological diseases, immune diseases, or a history of receiving drugs known to interfere with immune functions were excluded. Using the American College of Chest Physicians/Society of Critical Care Medicine (ACCP/SCCM) definition of sepsis, the patients were categorized into four groups: non-sepsis (group A) (n = 5) ; sepsis (group B) (n = 5) ; severe sepsis (group C) (n = 5) ; and septic shock (group D) (n = 5). The peripheral blood mononuclear cells (PBMCs) of each patient were isolated and cultured with human re-combinant granuloceyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-4 (IL-4) in vitro for 10 days. The cells were examined under an inverted microscope, scanning electron microscopy, and flow cytometry. The MTT colorimetric assay was used to observe the abilities of the dendritic cells to stimulale an allogeneic T lym-phocyte response in vitro. Paired t -test was used to compare changes in the surface markers among the different groups, Results The PBMCs in the four groups of patients differentiated into cells with typical dendritic configura-tions after in vitro cuhure with combined cytokines. The CD40, CD80, CD86, and HLA-DR expressions on the cell surfaces increased after culture,with (43.2±12.5)%/(27.3±9.3)%, (31.4 ± 10.1)%/(22.5 ± 8.7)%, (39.3±15.7)%/(21.9±7.7)%, and (75.4±25.6)%/(58.7±16.7)%, respectively. The stimulation index (the abilities of the dendritic cells to stimulale the allogeneic T lymphocyte response in vitro) in the four groups of patients after culture were (23.3±7.9) in group A, (18.9±8.3) in group B,(11.4±5.1) in Group C,and (5.5 ± 3.7) in Group D. Conclusions The immune functions of the dendritic cells of elderly patients with sepsis decrease in a linear manner with the severity of their septic state.

Objective To investigate the effect of arterial and venous subarachnoid hemorrhage ( SAH)on voltage-dependent calcium channel( VDCC)currents of cerebral artery smooth muscle cells and the relationship between the concentration of oxyhemoglobin( OxyHb)in arterial and venous blood and cerebral blood flow. Methods Thirty-six clean grade rats were colleted. A rat SAH model was induced by injection of autologous arterial or venous blood in suprasellar cistern using assisted stereotaxic apparatus. The rats were divided into three groups:an arterial SAH( n=14 ),a venous SAH( n=13 ),and a sham operation( n=9 )group. The arterial and venous OxyHb concentrations were measured. Three days after SAH modeling,a patch clamp was used to detect the relative surface area of the cerebral artery smooth muscle cells,resting potential,and VDCC currents in rats. A fluorescent microsphere method was used to quantitatively analyze cerebral blood flow(CBF). Results (1)Arterial SAH OxyHb concentration (127 ± 4 g/L)was significantly higher than venous SAH OxyHb concentration(54 ± 6 g/L),and that of the sham operation group was 50 ± 5 g/L. The differences were statistically significant among the 3 groups( P<0. 01).(2)The maximum current of VDCC of the arterial SAH group(3. 22 ± 0. 31 pA)was significantly higher than that of the venous SAH group(2. 19 ± 0. 27 pA)and the sham operation group(2. 18 ± 0. 29 pA). The differences were statistically significant among the 3 groups( P<0. 01 ). The VDCC currents of the arterial SAH group were consisted of L- and R-currents,while the currents of the venous SAH group were only consisted of L-VDCC.(3)The cerebral blood flow of the arterial SAH group(0. 83 ± 0. 14 mL/[g·min])was significantly higher than that of the venous SAH group(1. 28 ± 0. 28 mL/[g·min])and the sham operation group(1. 35 ± 0. 19 mL/[g·min]). The differences were statistically significant(P<0. 01). Conclusions The changing effect of arterial SAH on the expression and function of the cerebral artery smooth muscle cells are greater than that of the venous SAH. This difference may be associated with the concentration and composition of vasospasm factors of OxyHb in arterial and venous blood.
