ObjectiveTo explore the feasibility and efficacy of hyperbaric oxygen (HBO) therapy combined with mild hypothermi on severe craniocerebral injury (SCI).MethodsAll 80 SCI patients were randomly divided into therapeutic group (52 cases) and control group (28 cases). All patients received general synthesis treatment; while the hyperbaric oxygen combined with mild hypothermia treatment was added to the therapeutic group. Changes of Vm, Vs and PI of middle cerebral artery (MCA) in systolic stage were detected by transcranial-Doppler (TCD) before and after treatment. The plasma level of endothelin (ET) was also tested and prognosis of patients was analyzed.ResultsVm, Vs and PI of MCA in systolic stage improved obviously and ET reduced greatly in therapeutic group compared with those in the control group (P<0.01), and prognosis was also superior to control group.ConclusionHyperbaric oxygen combined with mild hypothermia can improve the consciousness state and prognosis of SCI patients as a result of the relaxation of the cerebral vascular spasm and the reduction of ET, which may contribute to the abatement of the cerebral ischemia and hypoxia.

OBJECTIVETo explore the role of Compound Danshen Injection (CDI) in regulating the expression of aquaporin 3 (AQP3) in human amnion epithelium cells (hAECs), and to study the relation between c-Jun N-terminal kinase (JNK) signal pathway and AQP3.

METHODShAECs were isolated and primarily cultured from term pregnancy with normal amniotic fluid volume and from term pregnancy with oligohydramnios, and then hAECs were further divided into four groups, i.e., the blank control group (A), the SP600125 group (B), the CDI group (C), and the SP600125 +CDI group (D). The cell viability was measured by cell counting kit-8 assay (CCK-8). The expression of total JNK, phosphorylated JNK, and AQP3 were determined by Western blot.

RESULTS(1) In hAECs with normal AFV or with oligohydramnios: There was no statistical difference in the cell viability or the expression of total JNK among the 4 groups (P > 0.05). But there was statistical difference in the expression of p-JNK (P < 0.05). Compared with A group, the expression of p-JNK was obviously down-regulated in B group, but obviously up-regulated in C group (P < 0.05). The expression of p-JNK was significantly lower in D group than in C group, but higher than that in A group or B group (P < 0.05).The AQP3 expression in the hAECs with normal amniotic fluid volume of C group and D group were higher than that in the A group (P < 0.05). However, there was no statistical difference in the AQP3 expression between C group and D group (P > 0.05). In hAECs with oligohydramnios, the expression of AQP3 obviously decreased in B group, but up-regulated in C group (both P < 0.05). The expression of AQP3 was lower in D group than in C group, but higher than in B group (P < 0.05).

CONCLUSIONCDI could regulate the AQP3 expression in hAECs with oligohydramnios via activating the JNK signal pathway.

Objective To investigate the pressure sources and coping styles of undergraduate nursing students and then help them cope with pressures positively and relieve the pressure .Methods Two hundreds and seventeen undergraduate nursing students in West China School of Medicine from four different grades were investigated with the Evaluation Scale about Practical Stress Sources and Level of Nursing Students and Simple Treatment Questionnaire.Results The overall pressure score was (43.848 ±14.253), and was the moderate pressure.The pressure source ranked first for the “worry about patient care mistakes or accidents ,” and the score was (1.829 ±0.830); the scores of pressure source from 1 to 4 grade were respectively (39.02 ± 16.773), (44.97 ±12.127), (47.48 ±13.607), (45.02 ±11.747), and the difference was statistically significant between two groups ( F =4.081, P <0.05); the average score of positive coping styles was (23.364 ±5.494), and the average score of negative coping styles was (10.949 ±4.675);coping styles often used to try to look at the good side of things;no significant difference was found in the average score of positive coping styles in all factors (P>0.05).The significant difference was found in the average score of negative coping styles in different household register , whether or not the only child, different grades (t =-2.157,-2.175, respectively;F=36.732;P<0.05), in which the average score of negative coping style in rural students was higher than that of city students and the score in non only child students was higher than that of the only child students.The average score of negative coping styles in different grade was analyzed by SNK , and the results found that the score of negative coping styles was increased from 1 to 4 grade.Conclusions Nursing educators should pay attention to the pressures of students from higher grade and countryside as well as the only child, and take effective measures to help them alleviate pressures and cope with pressures positively .

This study aims to investigate the characteristics of genomic variation of pandemic A/H1N1/2009 influenza virus isolated in Fujian Province, China. Complete genome sequence analysis was performed on 14 strains of pandemic A/H1N1/2009 influenza virus isolated from Fujian during 2009-2012. All virus strains were typical low-pathogenic influenza viruses, with resistance to amantadine and sensitivity to neuraminidase inhibitors. Eight genome fragments of all strains were closely related to those of A/California/07/2009 (H1N1) vaccine strain, with > or = 98.2% homology. Compared with the vaccine strain, the influenza strains from Fujian had relatively large variation, and variation was identified at 11 amino acid sites of the HA gene of A/Fujiangulou/SWL1155/2012 strain, including 4 sites (H138R, L161I, S185T, and S203T) involved inthree antigen determinants (Ca, Sa, and Sb). In conclusion, the influenza vaccine has a satisfactory protective effect on Fujian population, but the influenza strains from Fujian in 2012 has antigenic drift compared with the vaccine strain, more attention should therefore be paid to the surveillance of mutations of pandemic A/H1N1/2009 influenza virus.

OBJECTIVETo analyze the clinicopathologic factors related to recurrence and metastasis of stage II or III colon cancer after radical resection.

METHODSThe clinical and pathological data of 628 patients with stage II or III colon cancer after radical resection from Jan. 2005 to Dec. 2008 in our hospital were retrospectively reviewed and analyzed.

RESULTSThe overall recurrence and metastasis rate was 28.5% (179/628). The 5-year disease-free survival (DFS) rate was 70.3% and 5-year overall survival (OS) rate was 78.5%. Univariate analysis showed that age, smoking intensity, depth of tumor invasion, lymph node metastasis, TNM stage, gross classification, histological differentiation, blood vessel tumor embolus, tumor gross pathology, multiple primary tumors, preoperative and postoperative serum concentration of CEA and CA19-9, and the regimen of adjuvant chemotherapy were correlated to recurrence and metastasis of colon cancer after radical resection. Multivariate analysis showed that regional lymph node metastasis, TNM stage, the regimen of postoperative adjuvant chemotherapy, and preoperative serum concentration of CEA and CA19-9 were independent factors affecting the prognosis of colon cancer patients.

CONCLUSIONRegional lymph node metastasis, TNM stage, elevated preoperative serum concentration of CEA and CA19-9, the regimen of postoperative adjuvant chemotherapy with single fluorouracil type drug are independent risk factors of recurrence and metastasis in patients with stage II-III colon cancer after radical resection.

WU polyomavirus (WUPyV), a new member of the genus Polyomavirus in the family Polyomaviridae, is recently found in patients with respiratory tract infections. In our study, the complete genome of the two WUPyV isolates (FZ18, FZTF) were sequenced and deposited in GenBank (accession nos. FJ890981, FJ890982). The two sequences of the WUPyV isolates in this study varied little from each other. Compared with other complete genome sequences of WUPyV in GenBank (strain B0, S1-S4, CLFF, accession nos. EF444549, EF444550, EF444551, EF444552, EF444553, EU296475 respectively), the sequence length in nucleotides is 5228bp, 1bp shorter than the known sequences. The deleted base pair was at nucleotide position 4536 in the non-coding region of large T antigen (LTAg). The genome of the WUPyV encoded for five proteins. They were three capsid proteins: VP2, VP1, VP3 and LTAg, small T antigen (STAg), respectively. To investigate whether these nucleotide sequences had any unique features, we compared the genome sequence of the 2 WUPyV isolates in Fuzhou, China to those documented in the GenBank database by using PHYLIP software version 3.65 and the neighbor-joining method. The 2 WUPyV strains in our study were clustered together. Strain FZTF was more closed to the reference strain B0 of Australian than strain FZ18.

Objective:To explore the possible mechanism of electroacupuncture to improve detrusor hyperreflex after suprasacral spinal cord injury. Methods:A total of 60 female Sprague-Dawley rats were included. According to the random number table, twelve were selected as the blank group, twelve as the sham operation group, and the remaining 36 were made neurogenic bladder models using modified T₁₀ spinal cord transection. After that, twelve of them were randomly selected as the model group and twelve were as the electroacupuncture group from the model rats that met the requirements. On the 19th day after modelling, Ciliao (BL32), Zhongji (RN3) and Sanyinjiao (SP6) were taken for electroacupuncture. After seven days of continuous treatment, urodynamic testing was performed, content of cyclic adenosine monophosphate (cAMP) and protein kinase A (PKA) in detrusor was determined by ELISA, and the level of phosphorylation of myosin light chain kinase (p-MLCK) of detrusor was determined by Western blotting. Results:Compared with the blank group and the sham operation group, the maximum bladder capacity and bladder compliance significantly reduced (P < 0.01), and the base pressure and leakage point pressure of bladder significantly increased (P < 0.01); the content of cAMP and PKA in detrusor reduced (P < 0.01), p-MLCK in detrusor reduced (P < 0.05) in the model group. Compared with the model group, the maximum bladder capacity and bladder compliance increased (P < 0.01), the base pressure of the bladder and the pressure at the leak point decreased (P < 0.05); the contents of cAMP and PKA protein in detrusor increased (P < 0.05), the p-MLCK in detrusor increased (P < 0.05) in the electroacupuncture group. Conclusion:Electroacupuncture at Ciliao, Zhongji and Sanyinjiao points could improve the bladder function of rats with detrusor hyperreflex after complete spinal cord injury, and its mechanism may be related to up-regulating the expression of cAMP and PKA, phosphorylating and inactivating p-MLCK, which promote relaxation of detrusor.

OBJECTIVE: To evaluate the efficacy and safety of Tongxiening Granules (, TXNG) in the treatment of irritable bowel syndrome with predominant diarrhea (IBS-D). METHODS: A randomized, double-blind, double-dummy, and positive parallel controlled clinical trial was conducted from October 2014 to March 2016. Totally 342 patients from 13 clinical centers were enrolled and randomly assigned (at the ratio of 1:1) to a treatment group (171 cases) and a control group (171 cases) by a random coding table. The patients in the treatment group were administered orally with TXNG (5 g per time) combined with pinaverium bromide Tablet simulator (50 mg per time), 3 times per day. The patients in the control group were given TXNG simulator (5 g per time) combined with pinaverium bromide Tablets (50 mg per time), 3 times per day. The treatment course lasted for 6 weeks. The improvement of Irritable Bowel Syndrome Symptom Severity Score (IBS-SSS) was used to evaluate the primary outcome. Secondary outcomes included adequate relief (AR) rate, Irritable Bowel Syndrome-Quality of Life Questionnaire (IBS-QOL), Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), and the recurrence rate at follow-ups. Safety indices including the adverse events (AEs) and related laboratory tests were evaluated. RESULTS: Primary outcome: IBS-SSS at baseline, weeks 2, 4, 6 showed no statistical significance in both full analysis set (FAS) and per protocol set (PPS, P>0.05). After 6 weeks of treatment, the total effective rate of IBS-SSS scores in the treatment group (147/171,86.0%) was higher than the control group (143/171, 83.6%) by FAS (P>0.05). In regard to secondary outcomes, after 6-week treatment, there was no significant difference in AR rate, total score of IBS-QOL, improvement of HAMD and HAMA total scores between the two groups (P>0.05). The recurrence rate at 8-week follow-up was 12.35% (10/18) in treatment group and 15.79% (12/76) in control group, respectively (P>0.05). A total of 21 AEs occurred in 15 cases, of which 11 occurred in 8 cases in the treatment group and 10 AEs in 7 cases in the control group. The incidence of AEs had no statistical significance between the two goups (P>0.05). CONCLUSION Tongxiening Granules could relieve the symptoms of patients with IBS-D and the treatment effect was comparable to pinaverium bromide. (No. ChiCTR-IPR-15006415).

Objective: To analyze the course of disease and epidemiological parameters of COVID-19 and provide evidence for making prevention and control strategies. Methods: To display the distribution of course of disease of the infectors who had close contacts with COVID-19 cases from January 1 to March 15, 2020 in Guangdong Provincial, the models of Lognormal, Weibull and gamma distribution were applied. A descriptive analysis was conducted on the basic characteristics and epidemiological parameters of course of disease. Results: In total, 515 of 11 580 close contacts were infected, with an attack rate about 4.4%, including 449 confirmed cases and 66 asymptomatic cases. Lognormal distribution was fitting best for latent period, incubation period, pre-symptomatic infection period of confirmed cases and infection period of asymptomatic cases; Gamma distribution was fitting best for infectious period and clinical symptom period of confirmed cases; Weibull distribution was fitting best for latent period of asymptomatic cases. The latent period, incubation period, pre-symptomatic infection period, infectious period and clinical symptoms period of confirmed cases were 4.50 (95%CI:3.86-5.13) days, 5.12 (95%CI:4.63-5.62) days, 0.87 (95%CI:0.67-1.07) days, 11.89 (95%CI:9.81-13.98) days and 22.00 (95%CI:21.24-22.77) days, respectively. The latent period and infectious period of asymptomatic cases were 8.88 (95%CI:6.89-10.86) days and 6.18 (95%CI:1.89-10.47) days, respectively. Conclusion: The estimated course of COVID-19 and related epidemiological parameters are similar to the existing data.
