Objective To observe the feasibility of phase-rectified signal averaging applied for the evaluation of automatic nervous system activity in general anesthesia.Methods Forty-seven fe-males and 63 males aged 18-65 years,ASA falling into category Ⅰ or Ⅱ,scheduled for oral maxillo-facial surgery under general anesthesia were selected.The heart rate variability(HRV)signal was re-corded by Powerlab throughout the operation,and then it was sectioned into three segments with 5 minutes:pre-anesthesia(T0 ),means the waking state before the operation;intra-anesthesia(T1 ),the period of operation in 25-30 min;post-anesthesia(T2 ),the consciousness recovery state in the end of the operation.All indicators of HRV analysis was calculated in the time domain.SpO 2 ,MAP and BIS were recorded synchronously in the three periods.Results Compared with T0 ,DC, RMSSD, SDNN,SD1,SD2,logTP,logLF,logHF were significantly lower at T1 and T2 (P <0.05).In con-trast to T1 ,HR,MAP and BIS were significantly higher at T2 (P <0.05 ),DC,RMSSD,SDNN, SD1,SD2,logTP,logLF,logHF were significantly increased at T2 (P <0.05 ).There was positive relation between DC and RMSSD,SD1,logHF (r =0.905,0.909,0.932,respectively,P <0.01). Conclusion As 5 min-DC could indicate the character of PRSA,especially its specificity in showing vagus nerves activities,it is feasible that DC is used to observe the autonomic nerve activity intra op-eration.

Objective:The one-way communication between traditional LIS system and equipment has been unable to meet the needs of business development of medical laboratory in our hospital, we need to upgrade our equipment and to develop the bidirectional communication interface between LIS and equipment.Methods: Our hospital has invested a lot of money to upgrade previous One-way communication interface based on ASTM, the new instrument specifications conform to HL7 standard, and develop bidirectional transmission program based on HL7.Results: After the implementation of the bidirectional communication, testing equipment can automatically identify bar code to get the test request information, after the completion of the test instrument, the inspection unit can automatically send sample results to LIS.Conclusion: Bidirectional transmission improves the work efficiency, transmission based on HL7 is not only fast, but also conducive to the sharing of data between heterogeneous medical information systems, and it is a general tendency.

Objective To analyze the nursing effect of emotional disorder in patients with alcohol dependence.Methods From January 2009 to February 2010,81 patients in our hospital with emotional disorder of alcohol dependence were randomly divided into the observation group (41 cases)and the control group (40 cases).The control group was given routine nursing care,and the observation group was given enhanced care for emotional disorders on the basis of routine nursing care,the clinical results of two groups were compared.Results In the observation group,the re-drinking rate and readmission rate were19.5 ％ and 7.3％,significantly lower than 40.0％ and 27.5％ of the control group,the time interval of re-drinking of the observation group was significantly longer than the control group,the anxiety and depression scores were significantly better than the control group.Conclusions To give enhanced care on the basis of routine nursing care for patients with emotional disorders because of alcohol dependence has better clinical effect,it contributes to the patients′ rehabilitation.

AIM: To investigate the effects of different phacoemulsification incision for tear film stability in cataract patients.
METHODS: From January 2014 to September 2015, 108 patients (144 eyes) who underwent cataract surgery were divided into two groups: group A with clear corneal incision ( 52 cases with 74 eyes), group B with scleral tunnel incision (56 cases with 70 eye). Two groups of patients were taken the same incision width. Symptoms of dry eye and tear film break - up time ( BUT) were observed 1d before and 1d, 1, 3wk, 1 and 3mo postoperatively.
RESULTS:After performing cataract phacoemulsification 1d, 1wk, symptoms score of dry eye of group A was less than that of group B, the difference was statistically significant (t = -6. 199, -2. 871, P<0. 01), while at other times after operation there were no significant differences ( t = - 1. 639, - 0. 829, - 0. 301, P >0. 05); at postoperative 1d, 1 and 3wk, BUT of group B was better than those of group A, there were a statistically significant differences ( t = - 3. 718, -2. 342,-2. 506, P<0. 05), there were no significant differences at other the time after operation (t= -0. 882,1. 225, P>0. 05).CONCLUSION: The difference on effect of two different incision on the tear film stability only last a short time, which disappeared at 1mo after operation. The clear corneal incision has stronger impacts on tear film stability than scleral tunnel incision, while with a lower score on symptoms of dry eye.

Since the first reported case of swine influenza A in Mexico, a total of 15 510 cases have been confirmed in 53 countries by May 29, 2009. On April 29, 2009, the World Health Organization (WHO) raised its pandemic alert from grade 4 to grade 5. The virus is described as a new subtype of A/H1N1 and is not detected in pigs or humans previously. The virus is sensitive to oseltamivir and zanamivir, but resistant to amantadine and rimantadine. The genetics of the virus are so novel that humans are unlikely to have much immunity to it. The virus can transmit from human to human; therefore it is necessary to enforce quarantine measure for close contactors because the virus transmits during latency. Precaution methods like covering noses and mouths with a tissue when coughing or sneezing can reduce the transmission opportunity. Hands should be washed frequently with soap, especially after coughing or sneezing. Public places with ventilation conditions, personal health behavior and health condition are critical for the prevention and control of this epidemic.

Objective: To analyze evolutionary characteristics of the matrix protein (M) and nucleoprotein (NP) genes of influenza virus A/H1N1 in 2009 pandemic. Methods: The M and NP genes of A/H1N1 viruses were downloaded from NCBI database. MEGA4.0 software and NJ method were used for sequence alignment, protein sequence alignment, and the phylogenetic tree construction. Meanwhile, Epi Info software was used to analyze the linear trend of evolutionary distance of the M and NP genes of human H1N1 strains isolated during 1918 to 2009. Results: The M and NP gene sequences were similar among the novel A/H1N1 viruses, but different from those of the previous influenza H1N1 viruses. Using reference sequences of human H1N1 strains isolated during 1918 to 2008, we found that changes in evolutionary distances of the M genes between novel A/H1N1 strains and each of the reference A/H1N1 strains increased with increasing year intervals (Ptrend = 0.001). Compared with the amino acid sequence of M2 protein of reference human A/H1N1 virus strains isolated during 1918 to 2008, the novel A/H1N1 viruses had the amino acid substitutions at 6 sites: 11, 43, 54, 57, 77, and 78. Compared with swine and avian A/H1N1, the novel A/H1N1 virus only had the amino acid substitutions at 43 and 77. Conclusion: The NP gene of novel A/H1N1 virus, which is routinely considered as a conserved sequence, is different from those of the previously isolated human H1N1 influenza viruses; the related mechanisms and consequences on viral activity remain to be elucidated. The substitution to threonine at 11 and 43 amino acids of M2 protein might contribute to amantadine resistance of the novel H1N1 virus pandemic in 2009.
