OBJECTIVETo explore the immunological pathogenesis of multiple sclerosis (MS) patients of different TCM syndrome types.

METHODSFifty-nine MS patients were assigned to two types by syndrome typing according to their clinical manifestations, the Gan-Shen yin-deficiency (GSYD, 40 cases) type and the both yin-yang deficiency (YYD, 19 cases) type. Difference of patients' age of first attack, times of relapsing, duration of disease, MRI finding and evoked potential between the two groups were compared. The immunology indexes were also compared in part of the patients (26 cases in GSYD type and 12 cases in YYD type).

RESULTSThe age of first attack was later (P < 0.01), level of myelin basic protein in cerebrospinal fluid was higher (P < 0.05), in the YYD type than those in the GSYD type. Besides, the relapsing time in GSYD type, and the blood-brain barrier index and level of myelin basic protein in YYD type showed an ascending trend (P = 0.056, 0.074, 0.093, respectively).

CONCLUSIONImmunological difference exists between the MS patients of GSYD type and those of YYD type.

Objective To evaluate regional airway obstruction with balloon catheter in stabilizing the vital signs in experimental animals suffered from acute massive pulmonary embolism. Methods Pulmonary embolism of right lung artery by using auto-blood clots or detachable latex balloons was established in 27 healthy sheep. When the blood oxygen saturation decreased by 25% compared to that before the procedure,the placement of balloon catheter in corresponding right main bronchus was carried out in 18 sheep (study group). Five sheep were used as control group. The blood oxygen saturation in the remaining four sheep did not reach the intervention level. The pulmonary arterial pressure, the peripheral arterial pressure, the central venous pressure, the heart rate, the blood oxygen saturation, the arterial partial pressure of oxygen as well as of carbon dioxide were invasively determined. Results The experimental model of acute massive pulmonary embolism was successfully established in 23 sheep. After the establishment of pulmonary embolism, increased heart rate, tachypnea, a decrease of ≥ 25% in blood oxygen saturation within 30 minutes and a rise in pulmonary arterial pressure were detected. After the placement of balloon catheter in study group, a reduction of the pulmonary arterial pressure and an elevation of the blood oxygen saturation as well as the arterial partial pressure of oxygen rose. were observed. The difference between study group and control group was statistically significant (P < 0.05). Conclusion The result of this animal experiment indicates that obstruction of airway with balloon can be served as a first aid for acute massive pulmonary embolism, which can stabilizes the animal's vital signs and, therefore, can help gain precious time for the follow-up thrombolysis treatment.

Objective To improve the knowledge about controlling plague in cadres, masses, and the medical staff in plague affected area in Dinghian county of Shaanxi province and to assess the efforts of health education activities. Methods In 2008, the education activities carded out by the government-related departments were investigated. The awareness of plague control and assessment was obtained through a written survey, questionnaire and interviews on clinic. Results Some education activities were carried out in plague area of Dingbian county, such as training, issuing educational materials, broadcasting plague scientific educational films and arranging knowledge grand prix. The rates of knowing plague clinic, epidemiology, prevention and the "three prohibitions and three alerts to report" were as follows: the cadres were 50.50%(101/200),63.69%(414/650),78.67%(118/150), the masses were 64.71% (66/102),87.91% (269/306),76.47% (78/102) and the medical staff were 64.18% (543/846) ,68.51%(322/470),67.02%(63/94). The passing rates of the cadres, the masses and the medical staff were 70.00% (35/50),92.16% (47/51),74.47% (35/47). Conclusions Health education can strengthen health consciousness of cadres and masses and improve the ability of the medical stalf on controlling sudden epidemic situation. Reinforcing plague control knowledge and training of medical staff are still important for health education in the future.

Objective To investigate the antimicrobial resistant and transmission mechanisms of carbapenem-resistant K.pneumonia (CR-KP) infection of newborns.Methods A retrospective study was conducted on totally 37 non-repetitive CR-KP which were isolated from patients hospitalized between April 2011 and October 2013.Resistance genes were identified by PCR and sequencing.Plasmid was analyzed by pulsed-field gel electrophoresis (PFGE).Conjugation experiments were performed to determine the transferability of beta-lactamase.Multilocus sequence typing (MLST) was used to determine the genotypes and homology of these isolates.Out-membrane proteins were examined by PCR and sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE).Results Thirty-seven CR-KP isolates were tested.The resistant rates of imipenem, meropenem, ertapenem were 89.2％ (33/37), 83.8％ (31/37) ,97.3％ (36/ 37), respectively.All the 37 CR-KP exhibited 100％ (37/37) sensitivity to tigecycline, colistin, levofloxacin and amikacin, while resistance to most of the other antibiotics.By PCR, 67.6％ (25/37) isolates were blaNDM-1 positive, 35.1％ (13/37) isolates were blaIMP-4 positive and 2.7％ (1/37) isolate were blaIMP-8 positive, including two isolates carrying both blaNDM-1 and blaIMP-4.PFGE results showed that the isolates carried 2-4 plasmids and both blaNDM-1 and blaIMP-4 were transferable by plasmids.MLST assigned them to sequence type (ST) 20, ST17, ST54, ST705, ST290,which showed that there were infectious outbreaks caused by NDM-1-producing and IMP-4-producing respectively among newborns.SDS-PAGE result indicated that there was no absence of outer membrane proteins OmpK35 and OmpK36.Conclusions The main resistant mechanisms of CR-KP causing infection in newborns were those the isolates carried carbapenemase of blaNDM-1 or blaIMP-4 and the K.pneumonia with two kinds of carbapemenase were detected.
