OBJECTIVE: To observe the clinical efficacy of heat-sensitive moxibustion robot for improving the depressive state of methamphetamine addicts during withdrawal period. METHODS: A total of 60 patients with methamphetamine addiction accompanied with depressive state were randomly divided into an observation group (40 cases, 4 cases dropped out) and a control group (20 cases, 2 cases dropped out). The control group received routine health education and addiction treatment in compulsory isolation drug rehabilitation center. On the basis of the treatment in the control group, in the observation group, the heat-sensitive moxibustion robot was used to locate sensitive points at the Shenque (CV8) and Danzhong (CV17), and dual-point sparrow-pecking moxibustion was delivered for 60 min per session. The moxibustion therapy was performed 4 times in the 1st week, 3 times in the 2nd and 3rd weeks respectively, and 2 times in the 4th week, for 12 times totally. The scores of Hamilton depression scale (HAMD), self-rating depression scale (SDS), visual analogue scale (VAS) for drug craving, Hamilton anxiety scale (HAMA), self-rating anxiety scale (SAS), and Pittsburgh sleep quality index (PSQI) were observed before treatment, at the end of the 2nd and 4th weeks of treatment, and 4 weeks after the treatment completion (follow-up) in the two groups. RESULTS: At each time point after treatment, in the observation group, the HAMD, VAS, HAMA and PSQI scores were decreased compared with those before treatment (P<0.01, P<0.001); at the end of the 4th week of treatment and in follow-up, the SDS and SAS scores were decreased compared with those before treatment (P<0.001, P<0.01). Compared before treatment, there were no significant differences in the above scores at each time point after treatment in the control group (P>0.05). In the observation group, at each time point after treatment, the HAMD and VAS scores were lower than those in the control group (P<0.01, P<0.001, P<0.05); at the end of the 4th week of treatment and in follow-up, the SDS and HAMA scores were lower than those in the control group (P<0.05, P<0.001); at the end of the 4th week of treatment, the PSQI score was lower than that in the control group (P<0.01). CONCLUSION Heat-sensitive moxibustion robot effectively improves depression, anxiety and sleep quality, and reduces drug craving in methamphetamine addicts during withdrawal period.

From birth to adulthood, we often align our behaviors, attitudes, and opinions with a majority, a phenomenon known as social conformity. A seminal framework has proposed that conformity behaviors are mainly driven by three fundamental motives: a desire to gain more information to be accurate, to obtain social approval from others, and to maintain a favorable self-concept. Despite extensive interest in neuroimaging investigation of social conformity, the relationship between brain systems and these fundamental motivations has yet to be established. Here, we reviewed brain imaging findings of social conformity with a componential framework, aiming to reveal the neuropsychological substrates underlying different conformity motivations. First, information-seeking engages the evaluation of social information, information integration, and modification of task-related activity, corresponding to brain networks implicated in reward, cognitive control, and tasks at hand. Second, social acceptance involves the anticipation of social acceptance or rejection and mental state attribution, mediated by networks of reward, punishment, and mentalizing. Third, self-enhancement entails the excessive representation of positive self-related information and suppression of negative self-related information, ingroup favoritism and/or outgroup derogation, and elaborated mentalizing processes to the ingroup, supported by brain systems of reward, punishment, and mentalizing. Therefore, recent brain imaging studies have provided important insights into the fundamental motivations of social conformity in terms of component processes and brain mechanisms.

Bacteremia induced by periodontal infection is an important factor for periodontitis to threaten general health. P. gingivalis DNA/virulence factors have been found in the brain tissues from patients with Alzheimer's disease (AD). The blood-brain barrier (BBB) is essential for keeping toxic substances from entering brain tissues. However, the effect of P. gingivalis bacteremia on BBB permeability and its underlying mechanism remains unclear. In the present study, rats were injected by tail vein with P. gingivalis three times a week for eight weeks to induce bacteremia. An in vitro BBB model infected with P. gingivalis was also established. We found that the infiltration of Evans blue dye and Albumin protein deposition in the rat brain tissues were increased in the rat brain tissues with P. gingivalis bacteremia and P. gingivalis could pass through the in vitro BBB model. Caveolae were detected after P. gingivalis infection in BMECs both in vivo and in vitro. Caveolin-1 (Cav-1) expression was enhanced after P. gingivalis infection. Downregulation of Cav-1 rescued P. gingivalis-enhanced BMECs permeability. We further found P. gingivalis-gingipain could be colocalized with Cav-1 and the strong hydrogen bonding between Cav-1 and arg-specific-gingipain (RgpA) were detected. Moreover, P. gingivalis significantly inhibited the major facilitator superfamily domain containing 2a (Mfsd2a) expression. Mfsd2a overexpression reversed P. gingivalis-increased BMECs permeability and Cav-1 expression. These results revealed that Mfsd2a/Cav-1 mediated transcytosis is a key pathway governing BBB BMECs permeability induced by P. gingivalis, which may contribute to P. gingivalis/virulence factors entrance and the subsequent neurological impairments.

Objective:To identify the threshold of a health warning system based on the association of apparent temperature and years of life lost (YLL).Methods:Daily mortality records and meteorological data were collected from 364 Chinese counties for 2006-2017. Distributed lag nonlinear model and multivariate Meta-analyses were applied to estimate the association between the apparent temperature and YLL rate. A regression tree model was employed to estimate the warning thresholds of the apparent temperature. Stratified analyses were further conducted by age and cause of death.Results:The daily YLL rate was 23.6/10 5. The mean daily apparent temperature was 15.7 ℃. U-shaped nonlinear associations were observed between apparent temperature and YLL rate. The actual temperature-caused YLL rate for the elderly was higher than the young population. The daily excess deaths rate increased with the higher effect levels. Conclusions:Regression tree model was employed to define the warning threshold for meteorological health risk. The present study provides theoretical support for the weather-related health warning system.

Objective:To investigate the immunological features of 135 patients with corona virus disease 2019 (COVID-19), and to provide reference for the pathogenesis of the disease.Methods:The clinical and laboratory data of 135 confirmed COVID-19 patients in Guangzhou Eighth People′s Hospital from January 23 to February 29, 2020 were collected. The features of lymphocytes (CD4 + and CD8 + T lymphocytes, B lymphocytes, natural killer cells and natural killer T cells), and cytokines (interleukin (IL)-2, IL-4, IL-6, IL-10, tumor necrosis factor (TNF)-α and interferon (IFN)-γ) of patients at a median of 19 (14, 27) days of admission were analyzed. Kruskal-Wallis test, Mann-Whitney U test, chi-square test and Spearman rank correlation were used for statistical analysis. Results:Patients were divided into three groups according to the relevant diagnostic criteria, including mild group (14 cases), ordinary group (92 cases) and severe group (29 cases). Decreased CD4 + T lymphocytes were found in 44.4% (60/135) patients, while decreased CD8 + T lymphocytes were found in 42.2%(57/135) patients. Compared to mild group and ordinary group, level of CD4 + T lymphocytes in severe group was significant lower ( Z=4.379 and 3.799, respectively, both P<0.01), and level of CD8 + T lymphocytes was also significant lower ( Z=2.684 and 3.306, respectively, P=0.022 and 0.003, respectively). Decreased B lymphocytes were found in 25.3% (24/95) patients and significant different among the three groups, with the lowest levels ((88(56, 189)/μL; Z=6.199, P=0.045) and most frequency of decreased levels ((52.2%(12/23); χ2=11.723, P=0.003) in the severe group. Compared to the mild group and the ordinary group, IL-6 level in severe group was significant higher ( Z=-4.022 and -4.108, respectively, both P<0.01) and IL-10 level was also significant higher ( Z=-3.261 and -4.006, respectively, both P<0.01). Similar levels of IL-2, IL-4, TNF-α and IFN-γ were found among three groups (all P>0.05). The IL-6 level was positively correlated with the persistence of viral shedding ( r=0.301, P=0.007). Conclusion:The immune-mediated inflammation may be the important cause of disease deterioration of COVID-19, which might be the key target of the treatment of severe cases.

OBJECTIVE:To provide reference for better improving the risk perception of Omeprazole sodium for injection in nurses in a third-grade class-A hospital,strengthening risk management of ward drugs and ensuring safety of patients. METHODS:Nurses in the clinical departments in a third-grade class-A hospital where usage frequency of Omeprazole sodium for injection was relatively more were adopted as study subjects and a self-designed questionnaire was used to investigate on related knowledge on medication risk in nurses in emergency department,gastroenterology department,ICU and CCU in 2012 and 2014. RESULTS:51 and 81 questionnaires were distributed in 2012 and 2014,and 51 and 81 were effectively received with effective recovery of 100%and 100%,respectively. In both surveys,100% surveyed nurses could correctly choose one solvent at least,1.96% and 3.70%nurses could correctly choose 2 solvents;correct answering rates of intravenous administration time were 94.12% and 96.30%,re-spectively;correct answering rates of stable duration after preparation were both lower than 9%;correct answering rates of adverse reaction of this drug were 3.92% and 1.23%,respectively;correct answering rates of interaction of this drug were 1.96% and 6.17%,respectively;correct answering rates of stable formulation of this drug were 17.65%and 22.22%,respectively;the propor-tion of nurses observing ADRs were 25.49% and 13.58%,respectively;the proportion of nurses finding inappropriate compatibility were 15.69% and 22.22%,respectively,Ornidazole and sodium chloride injection was the most used incompatible drug;45% or more nurses hoping to strengthen the continuing education of nursing personnel. CONCLUSIONS:Nurses in this third-grade class-A hospital lack certain knowledge on the medication risk of Omeprazole sodium for injection,the drug risk management is not sufficient,and awareness prevention of drug risk is relative weak. It is suggested that the hospital should strengthen drug risk management system,nurses should strengthen the learning about drug risk and play the role of clinical pharmacists in the drug risk management to reduce the related drug risk and incidence of adverse reactions.

Objective To investigate the effect of propofol on autophagy in SD rat heart during myocar-dial ischemia-reperfusion (I/R) injury. Methods Twenty-one male SD rats were randomly divided into three groups as follows (n = 7): the sham operation group, in which rats underwent sham operation without tightening of the coronary artery sutures; the myocardial ischemia-reperfusion group , in which rats were induced by occlud-ing the left anterior descending coronary artery for 30 min , followed by 120 min reperfusion and 0.9% NaCl in-fusion at 3 mL/(kg·h) at 10 min before occluding the left anterior descending coronary artery; the myocardial ischemia- reperfusion- propofol group, in which rats underwent I/R and propofol infusion at 6 mg/(kg·h) at 10 min before occluding the left anterior descending coronary artery. Before tightening of the coronary artery, at 30 min post-tightening of the coronary artery and at 120 min post-reperfusion, HR、 LVSP and ± dp/dtmax of rats were recordedin each group. Atter 120 min post-reperfusion, the serum concentrations of cTnT was measured. The in-jured cardiac tissue was collected to investigate the ultrastructure change under the TEM and to determine the levels of mTOR and p-mTOR. Results No signifcant differences in HR, LVSP and ± dp/dtmax before tighten-ing of the coronary artery. But, at 30 min post- tightening of the coronary artery, compared with groupⅠ, the HR, LVSP and ±dp/dtmax were significantly decresed in groupⅡ and Ⅲ(P < 0.05). Then, at 2 h post-reper-fusion, compared with groupⅠ, the HR, LVSP, ±dp/dtmax and the level of p-mTOR were significantly de-creased, but the serum concentration of cTnT was significantly increased in groupⅡ(P < 0.05); but, compared with groupⅡ, the HR, LVSP, ± dp/dtmax and the level of p-mTOR were significantly increased, the serum concentration of cTnT and the level of mTOR were significantly decreased in group Ⅲ(P < 0.05). Conclusions These data suggest that propofol could heighten the level of p-mTOR, and attenuate the expression of mTOR dur-ing the myocardial ischemia-reperfusion injury in SD rats.

Objective To observe the clinical efficacy of wrist-ankle acupuncture in treating pain due to laparoscopic cholecystectomy.Method Totally 150 patients who were going to receive laparoscopic cholecystectomy were randomized into group A, group B, and group C, 50 cases in each group. Group A was intervened by wrist-ankle acupuncture prior to anesthesia, with the needles retained for 12 h; group B was by subcutaneous needling at the area nearby the points prior to anesthesia, with the needles retained for 12 h; group C didn’t receive any intervention before anesthesia. For the three groups, general inhalational and intravenous anesthesia was adopted for surgery, and patient-controlled intravenous analgesia for post-operation analgesia. The incision pain and visceral pain in the three groups were recorded by using Visual Analogue Scale (VAS) respectively 1 h, 2 h, 4 h, 8 h, 12 h, 24 h, 36 h, and 48 h after the operation. The total effective rate, analgesics consumption after operation, and incidence rate of adverse reaction were compared.Result There were significant differences in comparing the VAS scores of incision pain and visceral pain between group A and group C 4 h, 8 h, 12 h, 24 h, and 36 h after the operation (P<0.01,P<0.05). Between group A and group B, there were significant differences in comparing the VAS score of incision pain 8 h, 12 h, 24 h, and 36 h after the operation and the VAS score of visceral pain 12 h, 24 h, and 36 h after the operation (P<0.05). The total effective rate was 96.0% in group A, which was significantly different from 84.0% in group B and 86.0% in group C (P<0.05). The consumption of Fentaneyl citrate injection was (52.4±10.8)μg in group A, which was significantly different from (92.2±11.0)μg in group B and (107.2±11.5)μg in group C (P<0.05,P<0.01). The incidence rate of adverse reactions was 12.0% in group A, which was significantly different from 58.0% in group B and 66.0% in group C (P<0.01).Conclusion Wrist-ankle acupuncture plus patient-controlled intravenous analgesia can mitigate pain after laparoscopic cholecystectomy, and thus it can be taken as one of the post-operational analgesic approaches.

Along with sudden sensorineural hearing loss, hearing usually declines without any reason, which affects the patients′ work and life severely, and causes psychological problems like anxiety, fear, and many others. Because pathogenesis and pathomechanism of sudden sensorineural hearing loss are not yet clear according to domestic and overseas researches, there are not targeted therapies. Effective nursing intervention and health care guides can facilitate the patients with cognition of this disease, and then help them participate in the treatment positively and regain their hearing.

Objective To study the compatibility of TCM prescriptions of TCM practitioners of all dynasties of Alzheimer disease (AD). Methods Amnesia, forgetting, dementia, and idiot were set as search words to retrieve relevant literature in Encyclopadia of Traditional Chinese Medicine. Prescription information was screened and standardized to build database. Frequency analysis and association rules were used to mine TCM prescriptions and compatibility rules. Results Totally 449 AD related prescriptions were selected, involving 682 Chinese medicinal herbs. The individual herb with the highest frequency was Ginseng Radix Rhizoma (192);the herbal pair with the highest frequency was Ginseng Radix Rhizoma-Polyhalae Radix (182);the herbal combination with 3 Chinese medicinal herbs with the highest frequency was Poria with Hostwood-Ginseng Radix Rhizoma-Polyhalae Radix (79);the herbal combination with 4 Chinese medicinal herbs with the highest frequency was Polyhalae Radix-Ginseng Radix Rhizoma-Poria with Hostwood-Glycyrrhizae Radix et Rhizoma (37). The results of association rules showed that Ginseng Radix Rhizoma-Polyhalae Radix, Ginseng Radix Rhizoma-Glycyrrhizae Radix et Rhizoma, and Ginseng Radix Rhizoma-Poria with Hostwood were commonly used compatibilities in AD related prescriptions. Conclusion Treatment of TCM practitioners in all dynasties for AD mainly chooses Chinese medicinal herbs with the efficacy of tonifying qi and soothing nerves. The compatibilities and combinations are reasonable and with certain representativeness.
