Objective To study the effect of Qishenhuoxue granule on serum inflammatory response in children with pneumonia complicated with sepsis. Methods A total of 138 children with pneumonia complicated with sepsis who were admitted to our hospital from July 2014 to June 2016 were enrolled in this study. Children were randomly divided into observation group and control group. The patients in both groups were treated with conventional Western medicine symptomatic support. The observation group was treated with Qishenhuoxue granule. The curative effect was determined after treatment. Interleukin-6 (IL-6), interleukin-10 (IL-10), tumour necrosis factor-α (TNF-α), serum procalcitonin (PCT), hypersensitive C-reactive protein (hs-CRP), CD4+CD25+regulatory T cell (Treg cells) ratio value, creatine kinase-MB (CK-MB), creatinine (Scr), aspartic transaminase (AST) and brain natriuretic peptide (BNP) were measured before and 7 days after the treatment. Data of mortality and duration of pediatric intensive care unit (PICU) stay during treatment and adverse events were recorded during treatment. Results The total effective rate was 89.86% in the observation group, which was significantly higher than that of control group (71.01%, P<0.01). The levels of IL-6, IL-10, TNF-α, PCT, hs-CRP and Treg cell ratio were significantly lower after 7-day treatment in two groups than those before treatment (P<0.05), and levels of IL-6, IL-10, TNF-α, PCT, hs-CRP and Treg cell ratio were significantly lower in observation group than those in control group ( P<0.05). The CK-MB, Scr, AST and BNP were reduced after 7-day treatment in two groups, and those data were significantly lower in observation group than those of the control group (P<0.05). The 28-day mortality and the number of PICU days were significantly lower in observation group than those in control group (P<0.05). No adverse reactions were found in the both groups. Conclusion Qishenhuoxue granule can decrease the inflammatory response in children with pneumonia complicated with sepsis and improve the therapeutic effect. It is safe and effective and worthy of clinical recommendation.

Objective To evaluate the therapeutic effect of autologous hematopoietic stem cell transplantation(AHSCT)on hematological malignancies and solid tumors.Methods Twenty patients with age from 18 to 50 years received AHSCT.Two or 3 of following agents,Cytarabine(Ara-C)3～4 g/m2,Cyclophosphamide(CTX)4～6 g/m2,Etoposide(VP-16)0.5～1.0 g/m2,Semustine(me-CCNU)300 mg/m2,Melphalan(Mel)140 mg/m2,Thiotep a(TSPA)600 mg/m2,Carboplatin(CBP)1.0 g/m2,Busulfan 16mg/kg,were combined as conditioning regimen in all patients.Among them 2 patients with ALL accepted additional total body irradiation(TBI).Results All the patients have reconstituted bone marrow hematopoiesis after transplantation.None of them had the transplantation-related mortality.Among 20 patients with CML and malignant lymphoma,15 achieved disease-free survival(DFS)with a median survival time of 39.5(2～109)months.Conclusion AHSCT might represent an effective approach to the treatment of some patients with chemosensitive solid tumor who are complete remission or part remission.It is suggested that the patients have got a obvious survival benefit from AHSCT.

Objective To compare the successful ratio, efficacy and complications between ultrasound-guided and X-ray-guided endoscopic biliary drainage (EBD). Methods EBD was performed in 62 patients under ultrasound guidance and 54 patients under X-ray guidance. Serum bilirubin, the bile duct diameter and the changes of clinical symptoms were compared before and after the procedure. Results Tube placement was successfully achieved in 54 of 62 patients under ultrasound guidance and 51 of 54 patients under X-ray guidance. The serum direct bilirubin and the common bile duct diameter in patients with ultrasound guidance before and one week after procedure were (205.41±115.27) μmol/L vs. (106.47±82.16) μmol/L and (12.6±7.1) mm vs. (8.5±3.1) mm, respectively, with significant difference (all P values<0.05). Whereas they were (211.14±106.25) μmol/L vs. (110.89±59.47) μmol/L and (13.1±7.0) mm vs. (8.8± 3.2) mm, respectively, in patients with X-ray guidance (P<0.05). No complications such as abdominal pain, fever and elevated amylase were found in patients with ultrasound guidance, while 3 patients (5.9%) with X-ray guidence had above complications. Conclusions X-ray is a most effective method in guidance of EBD. However, ultrasound guidence, which may avoid unfavorable factors such as X-ray radiation and allergic contrast agent, has some advantages including real-time display, mobile convenience and emergency bedside application. It can instead of X-ray in performance of endoscopic nasobiliary drainage and endoscopic retrograde biliary drainage in patients with bile duct stone and mild narrow ducl caused by tumors.

AIM: To construct the shuttle plasmid vector for thymidine kinase (tk) and EGFP fusion protein gene driven by IGF - Ⅱ P3 promoter, and investigate the specific killing effect of the HSV - tk/GCV system on hepatocellular carcinoma(HCC) cells in vitro. METHODS: Recombinant shuttle plasmid vector was constructed by techniques of genetic recombination and screening, and identified by restriction digestion and sequencing analysis. Then the recombinant shuttle plasmid was transfected into HepG2 and HeLa cells by techniques of lipofectamine transfection and its expression was detected by fluorescence microscope and RT -PCR. Cell killing after ganciclovir(GCV) application was determined by MTT. RESULTS: Identification of pDC316 -tkEGFP- P3 by enzyme digestion and sequencing analysis showed that the length, inserted location and direction of the target genes which were inserted into the recombinant were correct. It was found that enhanced green fluorescence protein could only be seen in HepG2 cells, but not in HeLa cells. The results of RT -PCR showed that only two bands could be seen in the samples of pDC316 -tkEGFP- P3 transfected HepG2 cells. The MTT test showed the selective cytotoxicity of GCV to the transfected HepG2 cells. CONCLUSION: The shuttle plasmid vector carrying the tkEGFP fusion protein gene driven by IGF - Ⅱ P3 promoter has been constructed successfully and its specific expression in HepG2 cells provided a sound basis for targeted gene therapy for HCC.

BACKGROUND:Poly(3-hydroxybutyrate) is approved as its excel ent biocompatibility, biodegradability and piezoelectric properties, but there are also some deficiencies, such as high breakability and poor hydrophilicity. METHODS:Poly(3-hydroxybutyrate) was mixed with different mass percentages of nanohydroxyapatite (0, 10%, 20%and 30%) to prepare new composite fibrous scaffolds through electrospinning process. The microstructure, group composition, crystal ine phase distribution, thermal properties and surface wettability of the scaffolds were detected. RESULTS AND CONCLUSION:Under the scanning electron microscope, with the increase of nano-hydroxyapatite content, more and more nano-hydroxyapatite particles were distributed evenly on the composite fiber surface;the fiber surface was basical y covered with nano-hydroxyapatite particles at the content of 30%, and the roughness of the fiber surface also increased. Results from differential scanning calorimetry and X-ray diffraction showed that the nano-hydroxyapatite reduced the crystal inity of poly(3-hydroxybutyrate) and the crystal tacticity, and this phenomenon became more evident with the increase of nano-hydroxyapatite content. Additional y, the higher the content of nano-hydroxyapatite content, the lower the contact angle and the higher the hydrophily. These findings indicate that the nano-hydroxyapatite/poly(3-hydroxybutyrate) ultrafine-fibrous scaffold using electrospinning technology can effectively improve the surface wettability and crystal inity of the material as wel as the material hydrophily and brittleness, and the higher the content of nano-hydroxyapatite, the more obvious the effect.

Objective To evaluate the effect of consecutive diet nursing intervention on elderly patients with type 2 diabetes. Methods 56 elderly type 2 diebetes patients were randomly selected in control group and were given conventional type 2 diabetes management. The other 56 patients in experimental group were not only given routine care, but also 3 months of consecutive diet nursing intervention. At the 1st and 3rd month, assessment of blood glucose test and quality of life were conducted by all patients conducted. T test, chi-square test were used in the statistics. Results In experimental group, the controlling effect of fasting plasma glucose and 2-hour postprandial blood glucose have been significantly improved. 3 months after the consecutive diet nursing intervention, fasting plasma glucose of control and experimental groups were (7.18±0.89) mmol/L and (6.37±0.74) mmol/L (P=0.027). After 1 months of the consecutive diet nursing intervention, 2-hour postprandial blood glucose of control group and the experimental group were (11.69 ± 1.58) mmol/ L and (9.03 ± 2.13) mmol/ L (P = 0.028) respectively. After 3 months of intervention, the number were were (12.12±2.36) mmol/L and (8.36±1.65) mmol/L respectively (P<0.01). In the experimental group, the therapeutic dimension of quality of life has been gradually decreased and the difference was statistically significant. Conclusions Consecutive diet nursing intervention can effectively improve the blood glucose control of elderly type 2 diabetes patients.

AIM: To investigate the genetic and epigenetic alterations of p14~ ARF gene and mutation status of p53 gene in human primary colorectal carcinomas and to analyze the relationship between the two gene changes and the role of abrogation of the p14~ ARF -p53 pathway in colorectal carcinogenesis. METHODS: The homozygous deletions, mutations, methylation of 5′ CpG islands, mRNA expression of p14~ ARF gene and mutations of p53 gene were assessed by PCR, direct sequencing, methylation-specific PCR, and RT-PCR in the tumorous and matched adjacent normal colorectal tissues from 56 patients with colorectal carcinoma. RESULTS: ① p14~ ARF alterations were detected in 27% (15/56) of colorectal carcinoma tissues studied, of which 1 case showed homozygous deletion, 14 cases showed 5′ CpG island methylation, and no mutation was found in any tumor. ②15 colorectal carcinomas with p14~ ARF alterations indicated lack of (13 cases) or at low level of expression (2 cases) of p14~ ARF mRNA, while expression of the p14~ ARF transcript was detected in the remaining 41 colorectal carcinomas and any matched adjacent normal colorectal tissues. ③ The mutations of p53 gene were detected in 48% (27/56) of colorectal carcinomas investigated. ④ Of these 56 cases, 12 had p14~ ARF alterations alone, 24 had p53 mutations alone, 3 had both p53 mutations and p14~ ARF methylation, and 17 had neither. 70% (39/56) of the samples had either or both abnormalities of the two genes, and p14~ ARF hypermethylation was related to wildtype p53 (P

Aim To investigate whether genistein pro-tects paraoxon-induced vascular endothelial dysfunction through down-regulating p22phox and Nox4 expressions as well as inhibiting the generation of ROS.Methods In this study,thoracic aortas were isolated from the male Sprague-Dawley(SD)rats and were divided into the following groups:① control group,the thoracic a-ortas were incubated with dimethyl sulfoxide (DMSO, 0.1%)for 30 min;② genistein group,the thoracic a-ortas were incubated with genistein(100 μmol·L -1 ) for 30 min;③ paraoxon group,the thoracic aortas were incubated with paraoxon at the concentration of 40.5 μmol · L -1 for 30 min; ④ paraoxon plus genistein groups,the thoracic aortas were incubated with paraoxon (40.5 μmol·L -1 )plus genistein (100μmol·L -1 )for 30 min.The expressions of p22phox and Nox4 mRNA were detected by RT-PCR and the protein expressions ofp 2 2 phox and Nox4 were detected by Western blot.Results Compared with the control group,the expressions of p22phox and Nox4 were markedly increased in the paraoxon group. In the genistein group,the expressions of p22phox and Nox4 were significantly repressed. When treated with genistein plus paraoxon,there was a marked increase in the expression of Nox4(P <0.05),but no signifi-cant difference in the expression of p22phox.The ex-pression of p22phox in the paraoxon plus genistein group was significantly decreased(P <0.05)as com-pared with paraoxin group,but there was no significant difference in the expression of Nox4.Conclusion Paraoxon may result in oxidative damage of vascular endothelium through up-regulating p22phox and Nox4 expressions,genistein may down-regulate the expres-sions of both and protect vascular endothelium.
