OBJECTIVE To compare the effect of traditional swab sampling method on etiological surveillance of in-fectious diseases for large-scale object surfaces in hospitals and validate the samples processing method based on pre-wet anti-static fabric and modified polyethylene glycol(PEG)precipitation enrichment technology so as to im-prove the capability of early warning of infectious diseases and optimize the environmental surveillance program in the hospitals.METHODS The on-site surveillance was carried out for 8 times in 3 public hospitals(Shenzhen Longgang People's Hospital,the Second People's Hospital of Longgang and Longgang Maternal and Child Health Hospital)from May 2024 to Mar.2025.Totally 23 types of respiratory tract pathogens(18 types of viruses,5 type of pathogenic bacteria)and 6 types of gastrointestinal tract pathogens were simultaneously detected by means of fluorescent quantitative polymerase chain reaction(PCR);the actual isolation rates,etiological spectrum and cycle threshold(Ct)value were compared.The acrylic plate added with standards of different loads of H1NI influ-enza viruses was used as model for laboratory evaluation.The minimum detection limit,sensitivity and repeatabili-ty were observed and compared between the methods.RESULTS The minimum detection limit of both methods was 6.0 × 104 copies/ml,however,the positive rate of nucleic acid testing of the pre-wet fabric method was 100.00％(3/3),higher than 33.33％(1/3)of the swab method;when the low viral load was 6.0× 105 copies/ml,the average concentration of viral nucleic acid of the pre-wet fabric method(X-Ct=36.59)was higher,with the re-peatability(CV=0.99％,＜3.14％)better.The results of the on-site surveillances showed that the total isolation rates of pathogens of the pre-wet fabric method ranged between 42.84％and 64.27％,higher than between 10.71％and 21.43％of the swab method,with the isolated pathogens more abundant,the Ct value lower(P＜0.05).CONCLUSION The pre-wet fabric sampling enrichment method integrated with anti-static fabric sampling and PEG enrichment technology shows higher sensitivity and stability in the etiological surveillance of large-scale object surfaces,raising the isolation rate.

Objective To explore the effects of physiological deep-sea water(PDSW) on hyperthermal tolerance of Kunming (KM ) mice in the 45 .0 ℃ environment .Methods Deep-sea water from the south Chinese sea was processed ,and the metallic ele-ments dissolved in the DSW were analysed .The mice were randomly divided into 2 groups :the control group received tap water ;the experimental group treated with PDSW for 15 d .And then the mice were fed in the 45 .0 ℃ conditions .The survival time and histo-morphometric analyses of the brain ,lung ,heart ,liver and kidney were investigated .Results The survival time in PDSW-fed group was significantly longer than that of the control group (P< 0 .05) .Moreover ,histomorphometric analyses showed that PDSW could protect the brain ,lung ,heart ,liver and kidney of KM mice from the 45 .0 ℃ conditions .The results of western blot revealed that ex-pression of HSP72 of liver tissues for PDSW-fed group substantially increased ,when compared with the control mice(P< 0 .05) . Conclusion PDSW could improve hyperthermal tolerance of KM mice ,which maybe in the relation with expression of HSP72 pro-moted by PDSW .

Objective To retrospectively compared the hospitalization days and hospitalization costs of patients with thyroid tumor and breast cancer between patients who accepted selective hospitalization management and patients who accepted routine hospital management, and analyze the effect of selective hospitalization management to shorten the average hospitalization days.Methods A total of 419 patients with thyroid tumor and 318 patients with breast cancer who were treated in Fujian Provincial Hospital from March 2013 to February 2016 were chosen as the study object, and they were divided into the control group and the study group according to whether accepting the selective hospitalization management. Evaluating indicators included the total hospitalization days, preoperative hospitalization days, postoperative hospitalization days and hospitalization costs.Results Compared with the control group, the average total hospitalization days [(6.56±2.94)d vs (8.09± 3.71)d,(12.44±3.91)d vs (14.73±6.66)d)] and preoperative hospitalization days[(2.42±1.94)d vs (4.17± 2.68)d,(2.98±1.70) vs (5.29±4.00)d] in the study group were all reduced (P<0.05). There was no significant difference in the postoperative hospitalization days and the average hospitalization costs between two groups ( P > 0. 05 ) . Conclusions Selective hospitalization management could effectively shorten the hospitalization days of patients undergoing selective operation, and increase beds turnover rate. So the new management method would produce good social and economic benefits for the hospital.

OBJECTIVE:To investigate the characteristics and factors of ADR caused by Chinese patent medicine(CPM)and to provide reference for rational drug use and safety evaluation in the clinic. METHODS:158 cases of ADR caused by CPM collect-ed from our hospital during Jan.2009-Dec.2014 were analyzed. RESULTS:The occurrence of ADR caused by CPM was related to patient’s age,route of administration,category of drugs,irrational drug-use and so on. The incidence of ADR in patients over the age of 60 was the highest (31.01%),the largest number of ADR were caused by intravenous injection (79.11%),ADRs were most likely caused by blood-regulating preparation and dissipate blood stasis preparation (79.75%);ADR manifested as lesion of skin and its appendents(43.01%),followed by gastro-intestinal injury(16.06%)and whole-general injury(10.36%). The severe ADR was anaphylactoid reaction;after symptomatic treatment,the prognosis is good. CONCLUSIONS:According to syndrome differentiation and individual difference,CPM should be used rationally,and great importance should be attached to drug use moni-toring to reduce the incidence of ADR.

Objective To observe the therapeutic efficacy of 6% hydroxyethyl starch 130/0.4 (trade name: voluven) and polygeline on dog with hemorrhagic shock and their effect on immune function of red blood cells (RBC). Methods Eighteen dogs were randomized into three groups (n=6 in each group): normal sodium group, voluven group and polygeline group. Hemorrhagic shock models were set up according to Wiggers’ method. The mean arterial pressure value was bled to (45.56?3.69) mmHg within 10 min and maintained at this level for 60 min. Subsequently the dogs were resuscitated with normal saline or voluven or polygeline. The hemodynamics were measured before and 60 min after shock and 10, 30 and 60 min after infusion. The concentrations of MDA in plasm, C3b receptor garland rate (RBC-C3bRR) and RBC immune complexes garland rate (RBC-ICR) were measured. Results At 60 min after shock, MAP and CO were significantly lower than these before shock (P
