Objective:To study on the effect of ultrasound-guided thoracic paravertebral nerve (TPVB) block on quality of recovery from general anesthesia in tuberculosis patients with fiberboard exfoliation in post anesthesia recovery unit (PACU).Methods:From May 2018 to December 2019, 40 tuberculosis patients in Changsha Central Hospital with pulmonary fibreboard exfoliation and focal abscess lesions cleaning were randomly divided into two groups, with 20 patients in each group. The patients in group A received endobronchial general anesthesia and in group B received ultrasound-guided TPVB combined with endobronchial general anesthesia. Patients in the two groups were maintained under anesthesia by propofol, and the bispectral index (BIS) was maintained within the range of 40-50. The dosage of propofol and sufentanil was adjusted according to changes in BIS and hemodynamics. The mean arterial pressure (MAP), heart rate (HR) in two groups of patients were recorded at before anesthesia induction (T 0), before cutting leather (T 1), cut skin after (T 2), the end of operation (T 3), extubation time (T 4), and T 5 (time of leaving PACU). The visual analogue scale (VAS) of all patients in resting and cough state was recorded at 5, 30 min after extubation and the time of leaving PACU. The dosage of propofol and sufentanil in the operation and the additional dosage of sufentanil in PACU were recorded in both two groups. And the respiratory recovery time, consciousness recovery time, extubation time and sedation agitation scale(SAS) were observed. The adverse reactions such as nausea, vomiting, drowsiness and hypotension were observed in PACU. Results:Compared with group A, MAP and HR of patients at T 2, T 3, T 4, T 5 in group B were more stable during anesthesia, and VAS of patients in group B were lower than that in group A at each time point after extubation ( P<0.05). The dosage of sufentanil and propofol in group B were (35.92±8.12)μg and (749.56±95.30)mg respectively, which were significantly lower than those in group A [(45.74±4.42)μg and (862.83±105.34)mg, P<0.05]; the dosage of sufentanil in postoperative anesthesia recovery room of group B was (5.26±2.10)μg, significantly less than that of group A (10.35±5.86)μg ( P<0.05). The respiratory recovery time, consciousness recovery time and extubation time in group B were (12.92±5.12) min, (20.56±5.10) min and (26.87 ± 6.16) min, which were shorter than those in group A [(15.74±4.72)min, (25.83±5.34)min and (35.35±5.80)min, P<0.05]. The incidence of postoperative nausea, vomiting, lethargy and hypotension in group B were 10%, 10%, 35% and 20%, which were significantly lower than those in group A (30%, 20%, 75% and 45%, P<0.05). Conclusions:Ultrasound-guided paravertebral nerve block may significantly reduce the dosage of opioid analgesics for general anesthesia in tuberculosis patients with fiberboard exfoliation, accelerate the speed of anesthesia recovery, reduce the agitation during recovery, and improve the quality of anesthesia recovery.

ObjectiveTo investigate the clinical characteristics,epidemiology of patients with severe fever with thrombocytopenia syndrome bunyavirus (SFTSV) infection and genetic sequences of SFTSV.MethodsClinical data of five cases of severe fever with thrombocytopenia syndrome (SFTS)from Zhoushan Hospital during May 2011 to July 2011 were retrospectively analyzed.SFTSV gene was amplified by polymerase chain reaction (PCR).CD3+ CD4+ and CD3+ CD8+T lymphocytes were detected by flow cytometry (FCM).The sequences of isolated SFTSV strains were compared with those in GenBank. ResultsThe symptoms of continuous high fever,sore muscles,enlarged superficial lymph nodes,abdominal pain,diarrhea with gastrointestinal hemorrhage were observed.The white blood cells,platelets and CD3+ CD4+ T lymphocytes were progressive decreased in acute phase with the minimum of (0.97-2.00) × 109/L,(12-42) × 109/L and 7.52％-20.39％,respectively.The SFTSV was isolated from the sera of two patients.The sequences were compared with SFTSV sequences in GenBank.The homology of RNA-dependent RNA polymerase gene was 96％ compared with BX-2010,L-WWG,LN3,JS4,SD4,HN6 and AH12; the glycoprotein gene was 94％ ; N protein gene was 95％ compared with JS4,SD4 and LN4.The homology of the above three genes between two isolates was 99％.ConclusionsOur results suggest that SFTSV is sporadic in Zhejiang Province which is probably from native epidemic focus.SFTS is progressive and severe with acute onset.Multiple organ dysfunction is common in severe eases.

OBJECTIVETo investigate the anti-oxidative stress and anti-fibrotic mechanisms of adiponectin by examining effects on oxidative stress levels and expression of fibrosis-related signaling factors, including transforming growth factor-beta 1 (TGFb1), collagen I (COL-1), and the adenosine monophosphate-activated protein kinase (AMPK) pathway by using an in vitro HSC-T6 cultured cell system.

METHODSActivated HSC-T6 cells were pre-treated with 1.0 mug/mL adiponectin for 0, 30, 60 and 120 min, or left untreated to serve as controls, and both groups were then exposed to 5 mumol/L H2O2; a portion of the adiponectin-treated oxidative stress-induced cells were treated with an AMPK inhibitor (Compound C). The effects on mRNA levels of TGFb1. and COL-1 were analyzed by real-time PCR, in the levels of secreted TGF-b1 and COL-1 were detected by enzyme-linked immunosorbent assay of supernatants, and in the phosphoAMPK and AMPK protein expressions were detected by Western blotting.

RESULTSCompared to the H2O2 group without adiponectin pre-treatment, the H2O2 group with adiponectin pre-treatment showed significantly increased activity of superoxide dismutase (SOD), decreased content of malondialdehyde (MDA), and decreased gene and protein expressions of TGF-b1 and COL-1 (P less than 0.05). Moreover, inhibition of the AMPK pathway inhibited these adiponectin-mediated effects. The H2O2 group with adiponectin pre-treatment also showed increased levels of phospho-AMPK protein expression, with the maximum effect detected after 120 min of the adiponectin pre-treatment (P less than 0.01).

CONCLUSIONInhibition of oxidative stress is one of the mechanisms of the anti-fibrotic effects of adiponectin. Adiponectin can attenuate oxidative stress levels, resulting in down-regulation of TGFb1 and COL-1 expression through activation of the AMPK pathway.

UNLABELLEDObjective To explore the effects of sperm DNA integrity rate, acrosome integrity rate and acrosome reaction rate on the outcomes of rescue intracytoplasmic sperm injection (ICSI).

METHODSThis retrospective analysis was conducted among 97 infertile couples receiving rescue ICSI due to failure of in vitro fertilization procedures in our Reproductive Medicine Center. Of these 97 women, 41 had clinical pregnancy and 56 did not, and the effects of sperm DNA integrity rate (estimated by DNA fragmentation index, DFI), acrosome integrity rate and acrosome reaction rate on rescue ICSI outcomes were analyzed.

RESULTSNo significant difference was found in paternal age, testosterone value, testicular volume, FSH, female patient' age or the number of eggs retrieved between the two groups (P>0.05), but the infertility years was significantly shorter in the pregnancy group than in the non-pregnancy group (P<0.05). The fertilization rate and cleavage rate were similar between the two groups (P>0.05), but the good embryo rate was significantly higher in the pregnancy group (P<0.05). The sperm DNA integrity or acrosome reaction rate did not differ significantly between the two groups (P>0.05), but the acrosome integrity rate was significantly higher in the pregnancy group (P<0.05). The sperm DNA integrity rate, acrosome integrity or acrosome reaction rate were not correlated with the fertilization rate, cleavage rate or good embryo rate (P>0.05). The pregnancy rate, twin and single fetus rates were 42.3%, 10.3% and 32.0% in this cohort after recue ICSI, respectively.

CONCLUSIONRescue ICSI is an effective treatment after failed in vitro fertilization procedure, and sperm acrosome integrity rate is associated with the outcome of rescue ICSI.

Objective To explore the advantages and disadvantages of helicopter emergency medical services of South China in the long-distance transport for critical patients.Methods A total of 30 patients who received helicopter emergency medical services by Guangdong Generral Hospital from August 2004 to December 2014 were selected as the observation group,and the other 30 patients with similar conditions who received ground emergency medical services were selected as the control group.To analyses the difference between the two groups in the disease,transport distance,transportation time,costs and compliction by χ2-test,t-test and nonparametric test according types of data.Results There were significantly difference between two groups in transport distances (km) [578.0 (313.0,707.5)vs.214.5 (101.5,313.5),P <0.05],set-up time (min) [95.7 (56.7,133.4)vs.10.7 (6.8,15.7),P <0.05],transportation time (min) [112.3 (64.3,152.4) vs.146.8 (67.8,217.5),P <0.05],costs (yuan/h) [14378.5 (9887.0,16348.5)vs.557.0 (356.5, 787.5),P <0.05]and the distance/total time value [2.8 (1.3,4.8)vs.1.4 (0.8,2.8),P <0.05]. There was no significantly difference in the incidence of complications between two groups (χ2 =0.058,P >0.05).Conclusions Helicopter emergency medical services could shorten the transportation time of critical patients on long distance transportation,and improve the efficiency of first-aid.However,there were many disadvantages that need to be improved in the helicopter emergency medical service of China.

Objective: To develop a high efficient expression, purification system of recombinant arginine deiminase(ADI).Methods: cDNA fragment encoding for mycoplasma ADI was obtained by artificial synthesis and was cloned into prokaryotic expression vector(pBV220). The recombinant ADI was generated by the transformation of the recombinant vector into the host strain DH5?. Anion exchange and gel filtration chromatography was carried out for purification of the recombinant ADI. The biological activity of final product was detected by the assay of agrinine degradation in vitro. Results: A prokaryotic expression plasmid pBV220-ADI was generated successfully, and was identified by DNA sequencing; the recombinant protein was highly expressed in DH5?, the proportion of the recombinant protein is exceeded 35% of the whole protein. The inclusion bodies were solubilized with 6mol/L guanidine hydrochloride under reducing conditions in order to avoid incorrect disulfide-bond formation of the recombinant ADI molecules. Dilution and dialysis at lower degrees temperature were the optimum renaturation methods. After gel filtration, the purity and specific activity of rADI reached 95% and 80 IU/mg respectively. Conclusions: A set of protocols for high efficient rADI expression and purification has been established, which is simple, efficient and applicable.

Objective: This study aims to analyze factors associated with lymphovascular space invasion (LVSI) and evaluate the prognostic significance of LVSI in Chinese endometrioid endometrial cancer (EEC) patients. Methods: Five-hundred eighty-four EEC patients undergoing surgery in our center from 2006 to 2016 were selected for analysis. Univariate analysis and multivariate logistic regression were used to examine relevant factors of LVSI. To evaluate the prognostic role of LVSI, survival analyses were conducted. In survival analyses, both multivariate Cox regression and propensity score matching were used to control the confounders. Results: The incidence of LVSI was 12.16% (71/584). Diabetes history (p=0.021), lymph node metastasis (p=0.005), deep myometrial invasion (p<0.001) and negative PR expression (p=0.007) were independently associated with LVSI. Both Kaplan-Meier method and univariate Cox regressions showed LVSI negative and positive cases had similar tumor-specific survival (TSS) and disease-free survival (DFS). After adjusting for the influence of adjuvant therapy and other clinicopathological factors with multivariate Cox regressions, LVSI still could not bring additional survival risk to the patients (p=0.280 and p=0.650 for TSS and DFS, respectively). This result was verified by Kaplan-Meier survival analyses after propensity score matching (p=0.234 and p=0.765 for TSS and DFS, respectively). Conclusion LVSI does not significantly compromise the survival outcome of Chinese EEC patients.
