Objective To observe clinical efficacy of NB-UVB in treating psoriasis vulgaris and its effects on expression of serum interleukin-17 (IL-17),interleukin-23 (IL-23) and interleukin-22 (IL-22) in patients with psoriasis vulgaris,and to study the underlying mechanisms of NB-UVB.Methods Ninety patients were recruited and treated with NB-UVB therapy for 8 weeks.Before and after treatment,the serum level of IL-17,IL-23,IL-22,interleukin-l0(IL-10) and transforming growth factor(TGF-β) were tested by use of ELISA method,meanwhile Psoriasis Area and Severity Index (PASI) were used to evaluate clinical efficacy.Fifty healthy volunteers were selected as control group.Results Compared to healthy controls,the level of serum IL-17,IL-23 and IL-22 was significantly higher in patients with psoriasis vulgris (P ＜ 0.01),and IL-10,TGF-β shown lower expression in psoriasis patients (P ＜ 0.01).After 8 weeks of treatment with NB-UVB,serum levels of IL-17,IL-23 and IL-22 in psoriasis patients decreased significantly (P ＜ 0.01),while IL-10,TGF-βelevated significantly (P ＜ 0.01) in contrast.The Psoriasis Area and Severity Index (PASI) results indicated significantly clinical improvement after therapy,and the total effective rate was 87.78％.Conclusion NB-UVB could down-regulate serum IL-17,IL-23,IL-22 and up-regulate IL-10,TGF-β,which may help regulate imbalance of T lymphocytes cells of psoriasis patients.The clinical data demonstrate that the treatment of NB-UVB is a safe,effective method for psoriasis vulgaris.

Objective To obtain the length-chest circumference index of normal term newborns in different gestational age. Methods By cross-sectional time cluster sampling fact-ifnding investigation method, the anthropometric data on 16388 newborns from 2013 to 2015 were measured, including birth weight, length, crown-rump length, head circumference, and chest circumference, to develop normal full-term infants height chest circumference index (BCI) in different gestational age. Results Anthropometric data of 13776 normal term infants were available at the end of the study. The BCI, Ververck Index (VI), Elisma index (EI) were increasing with the gestational age at newborn. BCI, VI, EI in male is less than those of female with signiifcant difference (P<0.05). There were some differences of newborn’s BCI, VI and EI in 2015 than those in 2005. Conclusion Com-pared to ten years ago, chest fullness increased with gestational age at different gestational ages in normal full-term infants, and the chest fullness in male is less than that in female.

Objective To investigate the optimal measures and clinical effect of perioperative nursing care for patients with cephalocervical cancer treated with CT-guided radioactive 125I seed implantation. Methods Preoperative, intraoperative and postoperative continuous and comprehensive nursing was strictly carried out in 93 patients with cephalocervical cancer who underwent CT-guided radioactive 125I seed implantation treatment. The clinical results were analyzed and evaluated. Results The 125I seed implantation procedure was successfully accomplished in all 93 patients; the success rate was 100%. Shedding of 6 particles was observed in one patient, and shedding of 5 particles was observed in another patient; grade Ⅳskin injury was seen in 3 cases, which were improved after symptomatic treatment. All patients were uneventful at the time of discharge from hospital. Conclusion To ensure a successful CT-guided radioactive 125I seed implantation for the treatment of cephalocervical cancer, professional, meticulous and standardized nursing is the important guarantee.

The expression vector of SmIg scFv fragment was constructed in patient with B cell chronic lymphocyte leukemia (B-CLL) and expressed in E. coli to obtain scFv fragment, and the effect of the protein on the proliferation of stimulated peripheral blood mononuclear cells (PBMC) was investigated in vitro. Two pairs of primers were designed, and variable region genes of light chain and heavy chain were amplified by PCR respectively from the pGEM-T vectors previously constructed in our laboratory which containing light chain gene or Fd fragment of heavy chain gene. The PCR product was digested, purified and inserted into pHEN2 vector to construct the soluble expression vector pHEN2-scFv. After the induction by IPTG, the scFv protein was identified by SDS-PAGE electrophoresis and purified by Ni-NTA-Chromatography. MTT was used to determine the effect of purified protein on the proliferation of stimulated PBMC in vitro. Plasmid PCR and restriction enzyme digestion of pHEN2-scFv revealed the pHEN2-scFv vector was constructed successfully. Id-scFv protein was expressed in positive clone after induced by IPTG. SDS-PAGE analysis showed that the relative molecular weight of fusion protein was about 30 kD (1 kD= 0.9921 ku), which was consistent with the theoretically predicted value. Proliferation of PBMC could be induced by purified Id-scFv. It was suggested that the expression vector of SmIg scFv fragment was constructed successfully, and scFv protein was expressed and secreted from E. coli, which could induce proliferation of PBMC. This may lay an experimental foundation for further research of Id-HSP complex vaccine for B-CLL.

OBJECTIVE To study the feature of liver disease and liver failure complicated with fungous infection. METHODS The patients with liver disease complicated with fungous infection were collected form 1986 to 2005. The time was divided into four stages:from 1986 to 1990,from 1991 to 1995,from 1996 to 2000 and from 2001 to 2005. All patients with liver failure complicated with fungous infection in different stages were investigated for the incidence,the use of antibiotics and corticosteroids,the category and site of fungous infection and prognosis. RESULTS End-stage liver disease accounted for 82.6% and HBV infection was the main etiology in 475 cases of fungous infection. Fungous infection occurred mainly in hospital. Hospital acquired infection and community acquired infection were similar in different stages. The use of antibiotics and corticosteroids accounted for 88.8% and 48% in all patients before fungous infection,respectively. The use of antibiotics had no difference and the use of corticosteroids decreased in different stages. Candida were the main infection strains and the lungs and pharynx oralis were the main infection sites. The rate of healing and improvement of fungous infection and underlying diseases increased year by year. Healing and improvement rate of underlaying disease positively correlated with that of fungous infection. CONCLUSIONS End-stage liver disease patients are susceptible to fungous infection and Candida are the common infection strains. Lungs and pharynx oralis are the common infection sites. Anti-fungous therapy is important in the treatment of liver failure complicated with fungous infection.

OBJECTIVE To study clinical characteristics of liver failure with fungal infections in the elderly patients and risk factors associated with treatment failure.METHODS Eighty four elderly patients with liver failure followed by fungal infections since 1986 were divided into two groups: effective group and ineffective group.RESULTS The common pathogens were Candida albicans(58.33%),Aspergillus fumigatus(9.52%) and Candida tropicalis(8.33%).The lungs(43.88%),mouth(32.65%),intestinal tract(9.18%) and blood(5.10%) were the main sites of fungal infection.Among them after treatment,35 cases(41.67%) were effective compared with 49 cases(58.33%) ineffective.The risk factors for treatment failure included age,complication with multiple organ dysfunction syndrome(MODS) and aspergillosis.In multivariate analysis,we found MODS in patients was an independent factor in predicting the prognosis.CONCLUSIONS To improve the treatment outcome,important measures include preventing infection,enhancing the treatment of liver failure,monitoring and supporting multiple organs: heart,brain,lungs and kidneys,and promptly rational administration of antifungal agents in elderly patient with liver failure.

Objective To establish the Polock indexes (PI) of singleton neonates in different gestational age (GA),so as to provide a reference data for evaluating physical fullness and symmetry in neonates at birth.Methods A total of 16 887 live singleton neonates at 27-42 weeks of GA from two hospitals were measured at birth by site survey method using cluster samples by a cross sectional time in Shenzhen City,from 2013 to 2015 in this study,to establish PI of singleton neonates in different GA.Results The PI mean and the percentile curves(3rd,10th,25th,50th,75th,90th,97th)of singleton neonates at 27-42 weeks of GA (male,female,and unisex three groups) were established in 2015 in Shenzhen,China.The fullness and nutrition status of neonates at birth can be evaluated by these PI curves.According to the 3rd,10th,25th-75th,90th,97th curves,the down,mid down,middle,mid upper,upper levels were divided in turn.When the PI values ＞97th curve it was overweighted or fatty.When the PI values ＜ 3rd curve it was malnutrition.The lowest values of PI were at 27 weeks of GA,and the highest values appeared at 42 weeks of GA.The PI values were increasing with GA growth,which indicated that the GA increased the body density and fullness.The 50th percentile curve of male PI was higher than that of the female,and the male ratio increased by 61.2-89.5 at the gestational age of 27-34 weeks;between 35 and 42 weeks of fetal age,males increased by 104.8-149.1,which had a statistical difference (P ＜ 0.001).Conclusions The PI of singleton neonates rises with GA increase,which shows the GA increases the body density and fullness.PI is higher in male than in female singleton neonates.

Objective:To investigate the effects of methyltransferase-like protein 14 (METTL14)-mediated long-chain non-coding RNA EIF3J antisense RNA1 (Inc EIF3J-AS1) on the migration and invasion of cholangiocarcinoma cells and its mechanism.Methods:From September 2017 to December 2018, 10 pairs of cholangiocarcinoma and adjacent normal tissues were collected from the First Affiliated Hospital of Naval Medical University, which were surgically resected and pathologically confirmed. The expression of METTL14 mRNA and Inc EIF3J-AS1 in cholangiocarcinoma tissues was detected by fluorescence quantitative PCR, and the protein expression of METTL14 was detected by Western blotting. Cholangiocarcinoma cell lines HUCCTI and RBE were divided into control group and METTL14 or Inc EIF3J-AS1 knockdown group. The corresponding normal lentivirus was transfected in the control group, and METTL14 or Inc EIF3J-AS1 knockdown group was transfected with lentivirus that interfered with the expression of METTL14 or Inc EIF3J-AS1, respectively. Transwell assay was used to detect the ability of cell migration and invasion, and Western blotting was used to detect the expression of epidermal growth factor receptor (EGFR) and AKT protein.Results:The expressions of METTL14 mRNA and lnc EIF3J-AS1 in cholangiocarcinoma tissues were significantly higher than those in adjacent normal tissues (0.075±0.012 vs 0.031±0.006, 0.140±0.032 vs 0.064±0.012), and there was a positive correlation between expression of METTL4 mRNA and expression of lnc EIF3J-AS1 ( r=0.883, P=0.0007). The expression of METTL14 protein in cholangiocarcinoma tissues was higher than that in adjacent normal tissues (0.354±0.131 vs 0.187±0.183). Compared with the control group, the expression of lnc EIF3J-AS1 was significantly lower in METTL14 or Inc EIF3J-AS1 knockdown group (0.217±0.020 vs 1.000±0.052, 0.149±0.066 vs 1.000±0.045). The migration and invasion ability of cell lines HUCCTI and RBE decreased significantly in lnc EIF3J-AS1 knockout group (5.00±0.58 vs 23.33±0.33, 20.33±0.67 vs 70.67±0.33; 12.00±0.58 vs 25.00±2.52, 22.33±0.89 vs 43.67±0.33). The expression of EGFR and p-AKT/AKT protein were also significantly decreased (0.109±0.015 vs 1.000±0.018, 0.226±0.036 vs 1.000±0.051; 0.118±0.052 vs 1.000±0.069, 0.132±0.098 vs 1.000±0.023). The above differences were statistically significant (all P<0.05). Conclusions:Abnormal expression of lnc EIF3J-AS1 in cholangiocarcinoma mediated by METTL14 can promote tumor cell migration and invasion.
