Objective To analyze the value of pulse sequential continuous cardiac output(PICCO) in chronic pulmonary heart disease with cardiogenic shock.Methods Sixty-eight patients with chronic pulmonary heart disease complicated with cardiogenic shock were randomly divided into study group(n=36) and control group(n=32).Both groups were treated with conventional therapy,while the control group underwent deep venous puncture to monitor the central venous pressure (CVP) changes.The study group underwent deep venous catheterization+ femoral artery catheterization monitoring + PICCO monitoring.The therapeutic effect and the changes of PICCO index of the two groups were observed.Results The time of administration of vasoactive drugs,hospital stay and mechanical ventilation were significantly lower in the study group than in the control group (P＜0.05).There was no significant difference in mortality rate between the two groups(P＞0.05).After treatment,cardiac output quantity (CI) in study group increased significantly and extravascular lung water index EVLWI and PVPI decreased significantly,the difference between the two groups were statistical significance (P＜0.05),ITBVI had no statistical significant difference betweent two groups(P＞0.05).CI in the survival group was significantly higher than the death group,PVPI and EVLWI were significantly lower than the death group (P＜0.05),and the two groups had no significant difference in ITBVI (P＞0.05).Conclusion PICCO can reflect the hemodynamic status of patients with chronic pulmonary heart disease complicated with cardiac shock,and it has important clinical value for guiding the treatment and prognosis of patients.

BACKGROUND:Acellular matrix and annulus fibrosus-derived stem cells are both derived from the annulus tissue, and their tissue engineering complexes may have better biocompatibility. OBJECTIVE:To culture rabbit annulus fibrosus-derived stem cells on the porcine decellularized annulus fibrosus matrix, and to observe the growth of annulus fibrosus-derived stem cells on the decellularized matrix scaffold. METHODS:Decellularized annulus fibrosus matrix from porcine was prepared and detected by scanning electron microscopy, DAPI staining and Fourier transform infrared spectroscopy analysis. After isolation and culture, annulus fibrosus-derived stem cells were seeded onto the decellularized annulus fibrosus matrix. cellgrowth on the scaffolds was observed by cytoskeleton staining, inverted immunofluorescence microscopy and scanning electron microscopy to draw cellgrowth curve. RESULTS AND CONCLUSION:The prepared decellularized annulus fibrosus matrix was white and translucence liquid. The result of Fourier transform infrared spectroscopy indicated that the main component of the decellularized annulus fibrosus matrix was col agen. DAPI staining and scanning electron microscopy results showed no cells resident. The cytoskeleton staining displayed that annulus fibrosus-derived stem cells grew wel on the scaffolds at 1, 3, 7 days. These findings indicated that annulus fibrosus-derived stem cells have a good biocompatibility with the decellularized annulus fibrosus matrix in vitro.

Objective:To investigate the neuroprotective effects of simvastatin on lipopolysaccharide (LPS)-induced rat model ofParkinson's disease(PD) and the mechanisms involved.Methods:Hemiparkinsonian rat models were induced by stereotaxieal injection ofLPS in the right substantia nigra compacta.After2 weeks of simvastatin treatment, rotational behavior test was performed after the intraperitoneal injection of apomorphine.Expression of tyroxine hydroxylase (TH) and glial fibrillary acidic protein were analyzed through immunohistochemical staining of substantia nigra and striatum, and the level ofTNF-α was evaluated using enzyme-linked immunosorbent assay.Results:Comparing with untreated group, behavioral symptoms of the rats were significantly less in the rats that received simvastatin treatment.TheTH positive cell count in substantia nigra and striatum were significantly increased(P<0.05) andTNF-α expression was significantly decreased(P<0.05) in simvastatin group compared to untreated group.Conclusions:Simvastatin could effectively inhibit the activation of astrocytes, reduceTNF-α expression, and exert anti-inflammatory effects, and thus protect the dopaminergic neurons in substantia nigra and striatum of the rat model ofPD.

BACKGROUND:Zinc-modified calcium silicate (CaSiO3) bioceramics coating on the titanium surface prepared in preliminary experiments has good chemical stability and antibacterial property. OBJECTIVE:To observe the effects of zinc-modified CaSiO3 bioceramics coating on osteointegration. METHODS:MC3T3-E1 cels were respectively cultured on the titanium with zinc-modified CaSiO3 bioceramics coating (experiment group), titanium with CaSiO3 bioceramics coating (control group) and pure titanium (blank control group). Then, cel adhesion, proliferation, calcification rate and the expression of type I colagen and osteocalcin were detected. The implant materials mentioned above were respectively inserted into the femurs of New Zealand white rabbits, and after 1.5 months, the osteoproliferation and osteointegration between the implants and the host were tested. RESULTS AND CONCLUSION:In vitro experiment: The number of adhesive cels at 12 hours after co-culture was significantly increased in the experimental group compared with the control group and blank control group (P < 0.05). At 14 days after co-culture, cel proliferation ability and ability of calcium nodule formation in the experiment group were significantly better than those in the other groups (P < 0.05). At 21 days after co-culture, there was no significant difference in the expression of type I colagen, but the expression of osteocalcin in the experiment group was higher than that in the control group and blank control group (P < 0.05).In vivo experiment: In the experiment group, a large amount of bone substances were detected, the coating materials directly contacted with the bone interface, new bone tissues and little fibrous tissues were observed at the interface. In contrast, there was a small amount of bone hyperplasia in the control group and almost no bone hyperplase in the blank control group. Moreover, a small part of the implant directly contacted with the bone interface and the most part was separated from bone trabeculae by fibrous tissues. These findings indicate that zinc-modified CaSiO3 bioceramics coating can enhance the ability of osteointegration between titanium implants and the host.

Objective To study the relationship between ischemic stroke and gene polymorphism of an-giotensin-converting enzyme (ACE), apolipoprotein E (APOE) and methylene tetrahydrofolate reductase (MTHFR) among the population of Zhuang nationality in western Gui. Methods We directly sequenced ACE, APOE and MTHFR genes in 149 cases of ischemic stroke and 109 cases of normal people in western Gui. χ2 test was used to measure the relationship between gene polymorphism and ischemic stroke. Hardy-Weinberg genetic equilibrium test was used to evaluate the reliability of these data. Results In the ischemic stroke group, 62 cases, 22 cases and 65 cases carried II genetype, DD genetype and ID genetype in ACE. χ2 test showed no relationship between ACE gene polymorphism and ischemic stroke. In analysis of the polymorpism of APOE in the ischemic stroke and control group, no relationship between APOE gene polymorphism and ischemic stroke was found by χ2 test. MTFHR gene polymorphism was significantly related with ischemic stroke by χ2 test (P = 0.019). Conclusion Polymorphism of gene MTFHR but neither ACE nor APOE is significantly associated with ischemic stroke.

Objective:In order to accurately evaluate the postoperative rehabilitation of gynecological robotic surgery, a prediction model for evaluating postanesthesia care unit (PACU) extubation time and hospital stay in gynecological robotic surgery was established.Methods:The clinical data of gynecological patients who underwent robotic surgery in Xiangya Third Hospital of Central South University from October 2015 to May 2017 were retrospectively analyzed, and the data were screened to evaluate the postoperative recovery of patients from two aspects: PACU extubation time and postoperative hospital stay. Binary logistic regression was used to screen out the factors affecting PACU extubation time and postoperative hospital stay, and the prediction model was preliminarily established and verified.Results:Finally, there were 456 patients and 30 variables analyzed in the binary logistics regression. According to these variables, the prediction model of the postoperative recovery evaluation after gynecological robotic surgical procedures was established. Among them, age, intraoperative amount of atracurium and midazolam were independent risk factors affecting PACU extubation time (all P<0.05). American Society of Anesthesiologists (ASA) grade, intraoperative amount of midazolam, intraoperative bleeding and operation time were independent risk factors affecting postoperative hospital stay (all P<0.05). All models passed Hosmer lemeshow test (all P>0.05); The areas under the receiver operating characteristic curve (ROC) were 0.647 and 0.806, respectively. Conclusions:The prediction model of PACU extubation time and the postoperative hospitalization time has been established.

OBJECTIVETo understand the distribution of diarrheagenic Escherichia (E.) coli in population in Shanghai and discuss the practice model of cooperation in enteric infectious disease prevention and control between public health institution and hospital.

METHODSSentinel hospitals were assigned, standard detection and identification of diarrheagenic E. coli were conducted, incidence curve of diarrheagenic E. coli infection was drawn and epidemiologic survey and laboratory detection were conducted for suspect diarrheagenic E. coli infection outbreaks.

RESULTSA total of 7 204 stool specimens were collected from diarrhea patients in 4 hospitals during 2012-2013, in which 712 (9.9% ) were diarrheagenic E. coli positive, including 351 enteropathogenic E. coli (EPEC) strains, 292 enterotoxigenic E. coli (ETEC) strains, 32 enteroinvasive E. coli(EIEC) strains and 6 Shiga toxin-producing E. coli (STEC/EHEC) strains, as well as 31 mixed strains. EPEC infection mainly occurred in children aged 1-5 years; and all of these infections were caused by aEPEC. The incidence peak of ETEC infection was during August, the positive rate was >20%. The ETEC infection mainly occurred in infants aged 1-28 days in 2012 and in people aged 20-60 years in 2013 (P<0.05). ST was the major type (59.6%), followed by LT (27.8%) and ST/LT (12.6%). EIEC infection increased in children obviously in 2013 (P<0.01). No EHEC O157:H7 case was detected, but two EHEC O26:H11 (eae-hlyA-stx1a) cases in children were reported for the first time in Shanghai. The survey result indicated that the multidrug-resistant ETEC (STh-CS21-CFA/I-ClyA-EatA-ST2332-SHNL0005) strain causing outbreak in 15 newborns in Shanghai in 2012 was in the same clone as the strain detected in Zigong in Sichuan province.

CONCLUSIONSignificant change has occurred in diarrheagenic E. coli distribution in Shanghai in recent years, ETEC has potential risk to cause outbreak of hospital acquired infection in neonates and food borne infection. The active surveillance on ETEC and other enteric pathogens by both public health institutions and hospitals need to be improved.
