Objective: By sorting and analyzing pertinent modern studies targeting auricular point therapy treating primary insomnia (PI), to summarize the point selection rules and clinical efficacy of using auricular points alone or combining it with other therapies in treating PI. Methods: A search on China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP), PubMed, Springer and Ovid were conducted from January 1, 1998 till January 31, 2020. Point selection, diagnostic criteria and Pittsburgh sleep quality index (PSQI) in the eligible studies were analyzed and summarized. Results: The difference in PSQI before and after using auricular point therapy alone was more significant than that of using Chinese medication alone (P<0.05), but less significant than that of combining auricular point therapy and acupuncture-moxibustion and Chinese therapeutic massage (tuina) (P<0.05). In the included studies, Shenmen (TF4) was the most commonly used (370 times), followed by Heart (CO15), which was 344 times, and Subcortex (AT4), which was 325 times. In terms of auricular points distribution, points in the auricular concha were the most commonly used (1500 times), followed by those in the antitragus (474 times) and triangular fossa (387 times). Correlation analysis showed that Shenmen (TF4) and Liver (CO12), Sympathetic (AH6a) and Heart (CO15) were used together more often, followed by Shenmen (TF4), Liver (CO12), Spleen (CO13), Kidney (CO10) and Subcortex (AT4), and then Shenmen (TF4), Liver (CO12), Sympathetic (AH6a), Subcortex (AT4) and Heart (CO15). Cluster analysis showed that the auricular points used for PI can be divided into 6 clusters in 2 major groups. One group was Heart (CO15), Subcortex (AT4), Shenmen (TF4), Sympathetic (AH6a), Spleen (CO13), Kidney (CO10), Liver (CO12) and Endocrine (CO18); the other was Occiput (AT3), Stomach (CO4), Pancrease-gallbladder (CO11), Chuiqian (LO4), Small Intestine (CO6), Central Rim (AT2,3,4i) and Sanjiao (CO17). In terms of patterns in traditional Chinese medicine, the pattern of dual deficiency of heart and spleen accounted for the largest proportion in the studies of using auricular points alone or combining it with other treatments to treatment PI, and then it was the pattern of liver depression transforming into fire. Conclusion: In treatment of PI with auricular points alone or combo therapy involving auricular points, Shenmen (TF4) was commonly used, and the commonly used point group consisted of Shenmen (TF4), Liver (CO12), Sympathetic (AH6a) and Heart (CO15). Auricular point therapy can be taken as a complementary therapy in treating PI.

ObjectiveTo explore the mental health level of family members of stroke patient and related factors.Methods34 stroke patients' family members were tested with the Symptom Checklist-90(SCL-90), and compared with norms; SCL-90 factor scores, which were higher than that of norms, were analyzed for related factors.ResultsScores of 4 factors in the SCL-90 (somatization, depression, anxiety and phobia) were higher than norms in the family members of stroke patients. Scores of somatization factor correlated with the education background; depression factor correlated with the family income variable; anxiety factor correlated with the cognitive impairment variable of patients. In the correlation analysis with patient's activities of daily living (ADL) scores, somatization factor negatively correlated with total score of ADL and hygiene, feeding, bowel management, locomotion, bathing scores; both depression factor scores and positive item numbers negatively correlated with feeding and bowel management scores; phobia anxiety factor scores with hygiene, feeding, bowel management, communication, locomotion, bathing and total scores.ConclusionThe mental health level of family members of stroke patient is lower, and it is related to family income reduction, patient's cognitive impairment, and especially with the patient\s ADL level.

Based on the physiological properties of ammonium-resistant N2-fixingbacterium ( Klebsiella oxytoca NG13/pMC73A), the fermentation technology of it was studied. The basic medium of high-density culture was established, with glucose as carbon source coupled with appropriate nitrogen source and inorganic salts. At the middle and late phase of culture, glucose and ammonia were added to supply carbon source and nitrogen source, stabilizing the pHat 6.5 ~ 6.8. Optimal level of dissolved oxygen was kept by controlling aeration and stirring rate. Bacterium number of Klebsiella oxytoca NG13/pMC73A reached 600 ~ 700 x 10s cfu/mL at the end of culture. Compared with previous technology, bacterium number was increased by more than ten-fold with a comparable culture period.

Objective To explore influence of perioperative protection from hypothermia on surgical site infection (SSI) in patients undergoing gastroenteritic operation. Methods A retrospective study was carried out in 1536 patients undergoing gastroenteritic operation in general surgery department of our hos-pital.Patients (764 cases) admitted before July 2006 were set as the control group,while those after July 2006(772 cases) were set as the observation group. The observation group received a series of measures for protection from hypothermia besides of routine perioperative nursing.The control group only adopted routine perioperative nursing.The SSI rate was compared between the two groups. Results The SSI rate of the observation group was lower than that of the control group(P < 0.01 ). Conclusions Incidence of periop-erative hypothermia in patients undergoing gastroenteritic operation can increase the SSI rate.Appropriate measures for protection from hypothermia can prevent the incidence of hypothermia as well as SSI.

OBJECTIVE:To provide reference for rational drug use and strengthen the management of adjuvant medication man-agement in the hospital. METHODS:1 080 and 860 discharged medical records of 12 Vitamins for injection were selected from our hospital during Jun.-Nov. 2014 (pre-special comment group,i.e. group A) and Jun.-Nov. 2015 (post-special comment group,i.e. group B),respectively. The application of 12 Vitamins for injection,hospitalization stay,drug cost and the incidence of ADR were compared before and after adjuvant medication special comment. RESULTS:After adjuvant medication special comments,the propor-tion of drug use of no indication,unsuitable solvent selection,irrational drug dosage,drug use of drug interaction and contraindica-tion,drug cost and the incidence of ADR in group B were all lower than in group A,with statistical significance(P<0.05). There was no statistical significance in hospitalization stay between 2 groups(P>0.05). CONCLUSIONS:Clinical pharmacists adopt adju-vant medication special comments to effectively standardize clinical application of 12 Vitamins for injection in our hospital.

Objective To assess the strain and synchronism of left ventricular papillary muscles (PM) in functional mitral regurgitation (FMR) patients using two-dimensional speckle tracking echocardiography,and to explore the relation of PM function and the development of FMR.Methods Sixty ischemic cardiomyopathy patients with FMR and 60 idiopathic dilated cardiomyopathy patients with FMR were prospectively recruited.They were divided into three groups as the degree of FMR,patients with mild FMR was group F1,with moderate FMR was group F2,with severe FMR was group F3.Control group involved 42 healthy volunteers.The longitudinal peak strain of anterior and posterior PM (ALS,PLS),the peak time of longitudinal peak strain (APT,PPT),and the delay time of peak value between ALS and PLS (DT) were quantified.Results The ALS and PLS decreased company with increased of FMR degree (P ＜ 0.05,respectively),whereas the DT increased (P ＜ 0.05,respectively),and there was no significant variation trend of the APT and PPT.There was no intergroup difference of ALS and PLS,APT and PPT (P ＞ 0.05,respectively).ALS,PLS had negative correlation with LVM (P ＜ 0.05,respectively),and positive correlation with LVEF (P ＜0.05,respectively).DT had positive correlation with LVM(P ＜ 0.05),and negative correlation with LVEF (P ＜ 0.05).Conclusions The dysfunction and desynchronization of PM are closely related to the severity of FMR.The results may helpful to screen proper patients for cardiac resynchronization treatment.

Objective To explore the effects of insulation measures on blood coagulation during laparotomy in the aged patients. Methods Sixty patients were randomly divided into the experimental group and the control group with 30 cases in each group from September 2007 to August 2008. The experimental group received a series of insulation measures based on general perioperative nursing care, which was given to the control group. Patients' temperature, platelet count (PLT), prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TV),fibrinogen (Fbg) were measured and these preand postoperative values together with blood loss during operation were compared between two groups. Results No significant change was seen in perioperative body temperature in the experimental group, the incidence rate of hypothermia was lower, the change in coagulation index was better than that of the control group. Conclusions These results suggested that mild hypothermia could influence aged patients' blood coagulation function and increase blood loss during laparotomy. Active insulation measures can maintain the stability of patients" temperature.

Objective To investigate the feasibility of ~1H-MR spectroscopy(~1H-MRS)imaging to quantitatively detect fatty liver.Methods Twenty patients with fatty liver and 11 healthy volunteers underwent plain CT scan,conventional MR imaging and ~1H-MRS analysis.The blood lipid and liver function were tested on the same day as the MR examination.~1H-MRS sequence measured the peaks of H_2O and lipid,and the areas under the peaks.The relative contents of the lipid compound were calculated,and compared with the results of CT scan and liver function tests.Results The CT values of the normal group and the fatty liver group were(59?9)HU and(24?11)HU respectively.On ~1H-MRS a protruding high H_2O peak and a flat low lipid peak were observed in the normal group,while the protruding high H_2O peak and a high lipid peak appeared in the fatty liver group.The values of lipid peak in the normal group and the fatty liver group were(0.05?0.01)?10~5,(0.70?0.24)?10~5 respectively(t=4.32,P0.05),the areas under the lipid peak were(1.36?0.73)?10~9、(2.35?1.15)?10~9 respectively(t=5.21,P0.05).Conclusion ~1 H-MRS imaging is feasible to quantitatively detect liver fat and is a non-invasive method for detecting early fatty liver.
