OBJECTIVETo compare the efficacy differences on delayed encephalopathy after carbon monoxide poisoning (DEACMP) between acupuncture to restore consciousness combined with hyperbaric oxygen treatment and simple hyperbaric oxygen treatment.

METHODSForty-one patients with DEACMP were randomly divided into an observation group (21 cases) and a control group (20 cases). In the observation group, acupuncture was applied at Neiguan (PC 6), Shuigou (GV 26), Baihui (GV 20), Sishencong (EX-HN 1), Fengchi (GB 20), Hegu (LI 4), Sanyinjiao (SP 6) and Taichong (LR 3), and hyperbaric oxygen treatment was given as well. In the control group, simple hyperbaric oxygen treatment was used. The treatment was adopted once every day, and continuous 5 days' treatment made one session in the two groups. There were two days at the interval between two sessions and 6 sessions in the two groups. The changes of scores of mini mental state examination (MMSE) and Barthel index (BI) for activity of daily life and routine electroencephalogram (EEG) before and after treatment were compared.

RESULTSAfter treatment, the scores of MMSE and BI and EEG were all improved compared with those before treatment (all P<0.01). The raise of the scores of MMSE and BI in the observation group was more obvious than that in the control group (both P<0.05) and the improvement of EEG abnormal condition in the observation group was also superior to that in the control group after treatment (P<0.05).

CONCLUSIONAcupuncture to restore consciousness combined with hyperbaric oxygen could obviously improve the cognitive function, activity of daily life and changes of EEG, and it is better than simple hyperbaric oxygen treatment.

OBJECTIVETo investigate the effects of α3 neuronal nicotinic acetylcholine receptor (nAChR) on apoptosis and p38 signal transduction pathway in SH-SY5Y cells and to assess the roles of α3 nAChR in the pathogenesis of Alzheimer's disease (AD).

METHODSThe levels of α3 nAChR mRNA and protein were measured by real-time PCR and Western blot, respectively, in SH-SY5Y cells transfected with α3 nAChR siRNA. The mRNA level of bcl-2 and bax was measured by the real-time PCR. The siRNA transfected SH-SY5Y cells and control were then treated with 10 µmol/L Aβ25-35 for another 48 h, and the change in apoptotic rate and the levels of p-p38 and p38 were measured by flow cytometry and Western blot. Subsequently these SH-SY5Y cells were exposed to a blocker of p38 protein, and the apoptotic rate was measured again.

RESULTSCompared to the controls, the expression of α3 nAChR at mRNA and protein levels in the SH-SY5Y cells transfected with α3 nAChR siRNA decreased by 95% and 86%, respectively; the mRNA levels of bax increased 2.11 times and that for bcl-2 decreased 0.53 times. The apoptotic rate was unaffected (3.40% ± 0.20%); but it increased after Aβ25-35 treatment (24.52% ± 1.59%); the level of p-p38 protein also increased by 178% in the α3 nAChR inhibited cells treated with Aβ25-35. Compared to controls, the Aβ25-35-treated SH-SY5Y cells and the Aβ25-35-treated and siRNA-transfected cells both showed a reduction in apoptosis after treatment with p38 blocker, especially in the former.

CONCLUSIONThe siRNA silencing of α3 nAChR mRNA may enhance the effect of Aβ25-35 on the cell apoptosis by increasing the levels of p38 protein and bax mRNA and decreasing the level of bcl-2 mRNA, which may play a role in the pathogenesis of AD.

ObjectiveTo evaluate the impact of patient's heart rate(HR)on coronary CT angiography(CTA)image quality(IQ)and reconstruction timing in dual-source CT(DSCT).Methods Ninety-five patients with suspicion of coronary artery disease were examined with a DSCT scanner(Somatom Definition.Siemens)using 32×0.6 mm collimation.All patients were divided three groups according to the heart rate(HR):group 1,HR≤70 beats per minute(bpm),n=26;group 2,HR＞70 bpm to≤90 bpm, n=37;group 3,HR＞90 bpm,n=32. No beta-blockers were taken before CT scan.50-60 ml of nonionic contrast agent were injected with a rate of 5 ml/s. Images were reconstructed from 10%to 100% of the R-R interval using single-segment reconstruction. Two readers independently assessed IQ of all coronary segments using a 3-point scale from excellent(1)to non-assessable(3)for coronary segments and the relationshiD between IQ and the HR. ResuitsOverall mean IQ score was 1.31 ±0.55 for all patients with 1.08±0.27 for group 1,1.32±0.58 for group 2 and 1.47±0.61 for group 3. The IQ was better in the LAD than the RCA and LCX(P＜0.01).Only 1.4%(19/1386)of coronary artery segments were considered non-assessable due to the motion artifacts.Optimal image quality of all coronary segments in 74 patients(77.9%)can be achieved with one reconstruction data set.The best IQ was predominately in diastote(88.5%)in group 1,while the best IQ was in systole(84.4%)in group 3. ConclusionsDSCT can achieve the optimal IQ with a wide range of HR using single-segment reconstruction. With the increasing of HR,the timing of data reconstruction for the best IQ shifts from mid-diastole to systole.

OBJECTIVE: To investigate the validity and safety of trans-esophageal echocardiography (TEE) in monitoring of Nuss surgery. METHODS: A total of 140 patients with pectus excavatum from Sichuan Provincial People's Hospital underwent Nuss surgery from August, 2011 to Aμgust, 2013. Among them, 72 patients received TEE monitoring while 68 patients didn't. The injury of heart and large vessels by the introducer and Nuss steel bar was observed by intraoperative TEE monitoring under middle-esophageal four chamber view and middle-esophageal aortic short axis view. RESULTS: The operation in all patients had been performed successfully without any severe complications. Satisfactory TEE images were obtained in all patients. The procedure of inserting the inducer and Nuss steel bar behind sternum and steel bar overturn could be seen clearly. No injury in heart and large vessels was detected. Local streak-like hemorrhage in 3 patients was observed under intra-operative TEE screen, but no further new bleeding was found in postoperative TEE examination. The blood was absorbed and couldn't see under trans-thoracic echocardiography in 1 month after the operation. CONCLUSION The TEE is a non-invasive monitoring method. It is sensitive to detect the status of the heart and large vessels and can prevent the severe complications due to Nuss surgery.

OBJECTIVETo investigate the effect of diet-induced obesity on the apoptosis of testicular spermatogenic cells in pubertal male rats.

METHODSForty healthy male rats were equally and randomly divided into a control and a high-fat group, the former fed on normal diet, while the latter high-fat and high-calorie diet. The testes of the rats were harvested at the end of 10 weeks for detection of total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) in the peripheral blood with the automatic biochemical analyzer. Pathological changes of the testis were observed under the light microscope, the apoptosis of the testicular cells detected by TUNEL, the expressions of Bcl-2 and Bax proteins determined by immunohistochemistry, and those of Bcl-2 mRNA and Bax mRNA measured by RT-PCR.

RESULTSThe levels of TC, TG, LDL-C and HDL-C were significantly higher in the high-fat group (5.17 +/- 0.17, 1.18 +/- 0.09, 1.76 +/- 0.11 and 5.08 +/- 0.18) than in the control (1.38 +/- 0.12, 0.39 +/- 0.05, 0.97 +/- 0.07 and 0.75 +/- 0.06) (P < 0.05), so was the apoptotic index of spermatogenic cells (37.17 +/- 2.74 versus 5.16 +/- 0.81, P < 0.01), and the apoptotic spermatogenic cells were mainly spermatogonia and spermatocytes. The expressions of Bax protein and Bax mRNA were markedly higher in the high-fat group (153.26 +/- 8.74 and 1.08 +/- 0.12) than in the control (101.81 +/- 6.14 and 0.37 +/- 0.04) (P < 0.01), while those of Bcl-2 protein and Bcl-2 mRNA remarkably lower in the former (139.26 +/- 7.21 and 0.46 +/- 0.05) than in the latter (159.37 +/- 8.96 and 1.05 +/- 0.11) (P < 0.01).

CONCLUSIONDiet-induced obesity can increase the apoptosis of spermatogenic cells in the rat testis, which may be associated with the reduced expression of Bcl-2 and elevated expression of Bax.

Objective To assess the clinical predictability of waist-to-hip ratio (WHR) among female civil servants who had experienced risk factors of cardiovascular disease. Methods Data was gathered from 4153 female civil servants aged 21-91 y working at universities who were enrolled in health screening centre at the Second Hospital Attached to Hebei Medical University, in 2006. WHR quartiles were determined as: <0.80, 0.80-<0.84, 0.84-<0.90 and ≥0.90. Subjects were placed into high-risk categories for cardiovascular disease on the basis of national health reference on range norms of protocol including hypertension, diabetes mellitus and dyslipidemia. Results Participants had an increased likelihood of hypertension (systolic blood pressure) , dyslipidemia (elevated triacylglycerol and descending HDL-C) and diabetes mellitus at WHR≥0.84. All aforementioned variables had a significant odds ratio at WHR ≥0.84. This trend was further persisted after adjustment had been made on smoking, age, and BMI. Descended HDL-C was observed at the 0.80≤WHR<0.84 when compared with WHR< 0.80. Conclusion These data indicated an upward shift in the critical threshold for WHR to ≥0.84. Above which point, there was an elevation of risk factors on cardiovascular diseases among all the female civil servants. The trend persisted regardless of smoking, BMI

December 2019 witnessed the outbreak of COVID-19 in Wuhan city and its rapid spread to other parts of China, and overseas as well. Tongji Hospital, as a designated hospital for treatment of critically ill patients, shoulders the diagnosis and treatment tasks of numerous critically ill patients of such a disease. For the purpose of handling their medical records and effectively preventing the nosocomial infection of the disease, the hospital puts in place both the electronic signature system of patients based on a Wechat applet and a paperless medical record total solution based on the data center. These measures overcome the challenges incurred by patients’ signature on paper-based records and medical records archiving during the epidemic. On the other hand, they can not only downsize the paper-based medical records, minimize the risk of infection caused by paper-based medical records via contacts, but also effectively save the hospital of its operating costs and improve its efficiency of clinical work.
