Objective The clinical features of elderly patients with severe acute pancreatitis (SAP) were atypical and these patients were often misdiagnosed as having paralytic ileus. The clinical presentations of elderly patients with SAP whose first diagnosis as paralytic ileus were analyzed. Methods 18 patients of elderly SAP who were misdiagnosed as having paralytic ileus were included and the clinical data were compared with 58 elderly patients with SAP. Results Among the misdiagnosis group, the first symptom onset were fleus, abdominal distension, vomiting, constipation, abdominal pain, diarrhea for 5, 4, 3, 3, 2, 1 case, respectively. Among SAP group, the first symptoms onset were 2, 31, 9, 3, 11, 2 cases, respectively. For misdiagnosis group, 13 cases were correctly diagnosed by CT scan, 3 cases by ultrasound and 2 cases by serum amylase test. For SAP group, 32, 15, 11 cases were diagnosed by CT scan, ultrasound and serum amylase, respectively (P < 0.05). 4 and 13 patients died in misdiagnosis and SAP group, respectively; among these 13 patients, 10 were female and 3 were male. Conclusions The elderly patients with paralytic ileus should consider the possibility of SAP, and CT scan was valuable for correct diagnosis.

Objective To investigate the effects of intra-articular hyaluronan(HA)injection on the expression of cartilage oligomeric matrix protein(COMP)in synovium of strenuous running rats,and investigate the possibility of predicting the effectiveness of HA based on COMP in synovium.Methods 36 healthy male Wistar rats were randomly divided into control group,strenuous running group and strenuous running group and HA injection group.Strenuous running group and HA injection group were intra- articularly injected with HA once a week for 5 consecutive weeks.The histological changes of synovium of knee joint was examined by H.E.staining and immunohistochemical expression of COMP in three groups after 6 weeks' strenuous running.Results Synovial inflammation was less severe in strenuous running and HA injection group than strenuous running group(t =7.15,P ＜0.01).The immunohistochemical expression of COMP in rats'synovium of knee joint in strenuous running and HA injection group was significantly lower than that in rats'synovium in strenuous running group(t = 6.30,P ＜ 0.01).Conclusions Intra- articular HA injection suppressed synovitis,and the expression of COMP in synovium could be used to predict the effectiveness of HA.

The practice of general practice emphasizes that the general practitioner is the backbone, and the primary health institution is the main body, which solves the main health problems of the commu-nity and meets the basic health service needs of the residents. Rehabilitation medicine occupies a prominent position in the community health service, and its related knowledge and skills are the important part of the whole medical education. However, rehabilitation medicine has more teaching contents, less training time and out-of-date teaching model, which have made the effect of rehabilitation medicine teaching not good. In the rehabilitation medicine teaching for training general practitioners, by strengthening the concept of reha-bilitation, elaborating teaching content, optimizing teaching ward-round, and outstanding ability as well as reforming evaluation way, we try to exercise the students' clinical thinking and improve clinical skills, to cultivate outstanding qualified general medical practitioners for community rehabilitation ultimately.

Heme oxygenase-1 (HO-1) is a cytoprotective enzyme that catalyzes the conversion of heme to CO, biliverdin, and iron, which together protect cells from oxidative and inflammatory damage and play an important role in maintaining cell homeostasis. In recent years, HO-1 has also been found to have antiviral biological effects, and the induced expression of HO-1 inhibits the replication of various viruses such as hepatitis C virus, hepatitis B virus, human immunodeficiency virus, dengue virus, ebolavirus, influenza A virus, Zika virus, severe acute respiratory syndrome coronavirus 2, human respiratory syncytial virus, hepatitis A virus and enterovirus 71. The inhibitory effect of HO-1 on these viruses involves three mechanisms, including direct inhibition of virus replication by HO-1 and its downstream products, enhancement of type I interferon responses in host cell, and attenuation of inflammatory damage caused by viral infection. This review focuses on the recent advances in the antiviral effect of HO-1 and its mechanism, which is expected to provide evidence for HO-1 as a potential target for antiviral therapy.

AIM: To investigate the role of brainstem auditory evoked potential(BAEP) in the early diagnosis of diabetic central neuropathy (DCN) and to probe into the relationship between plasma nitric oxide (NO) and DCN. METHODS: Experimental diabetes(ED) rat model was used. BAEP and plasma NO were measured dynamically after ED modeling. RESULTS: The peak latency (PL) of Ⅰ, Ⅲ, Ⅳ and V and the interpeak latency (IPL) of I-III and III-V of BAEP in ED group prolonged after 4 weeks of ED modeling (P＜0.05). All PL and IPL of BAEP prolonged after 6 weeks、8 weeks and 10 weeks (P＜0.01). The plasma NO increased to the top in ED group at 2 weeks and then decreased gradually. There was negative correlation between plasma NO and PL and IPL of BAEP. CONCLUSION: BAEP was sensitive and valuable in the early diagnosis of DCN. Reduction of plasma NO may play a role in the pathogenesis of DCN.

The bioactivities, chemical composition and distribution of aerial parts of Panax species are different from the roots. The present paper summarized the phytochemical and analytical studies of aerial parts of Panax species, including P. ginseng, P. notoginseng, P. quinquefoliun and P. japonicus. This review aims so as to provide scientific evidences for further investigation of chemical profile, quality control and optimal utilization of these resources.

OBJECTIVETo explore the protection effects of acupuncture on glaucomatous optic nerve damage and its mechanism.

METHODSExperimental glaucoma model was induced by intracameral injection of compound Carbomer solution in rabbits. After 28 days, ocular tension returned to normal by filtration surgery. Twenty rabbits (40 eyes) were randomly divided into a model group, an acupuncture group, a neurotrophy group and a nomal control group, 5 cases in each group. The acupuncture group was treated with acupuncture at bilateral "Qiuhou" (EX-HN 7),"Fengchi" (GB 20) and "Xingjian" (LR 2), twice a day. The neurotrophy group was treated with intramuscular injection of Vitamin B1 (100 mg) and Vitamin B12 (500 microg), once a day, and the other groups with no treatment. The expressions of Bcl-xl and BDNF in rabbits retina were observed after 4 weeks.

RESULTSAt the end of the experiment, the positive expression cells of Bcl-xl and BDNF were (31.20 +/- 5.97) per mm2 and (6.3 +/- 1.89) per mm2 in the acupuncture group, being significantly higer than (26.70 +/- 4.32) per mm2 and (4.0 +/- 1.89) per mm2 in the model group (both P<0.05).

CONCLUSIONAcupuncture can raise the expression of Bcl-xl and BDNF of retina, so as to prevent optic nerve damage caused by intraocular hypertension.

Objective To discuss the influence of hierarchical management mode on psychological empowerment and innovation behavior of nurses in intensive care unit (ICU). Methods From April 2016 to April 2017, hierarchical management mode was applied among 41 ICU nurses in Shanxi Provincial People's Hospital for 12 months. The levels of psychological empowerment and innovation behavior were compared before intervention, on the 6th and the 12th month after intervention. Results Before the intervention, the score of the psychological empowerment was (3.07±0.46), which was at a middle level. Meanwhile, the score of innovation behavior was (2.91±0.40), which was at a low level. With the implementation of hierarchical management mode, the differences in the scores of each dimension and the total score of psychological empowerment were statistically significant (F=11.463, 27.192, 13.700, 36.609, 45.733;P<0.001). The differences in the scores of each dimension and the total score of innovation behavior were statistically significant (F=43.149, 106.489, 21.836, 80.586;P< 0.001). Conclusions ICU nurses' psychological empowerment is at a moderate level, and individual innovative behavior is at a weak level. Hierarchical management mode helps to improve ICU nurses' psychological empowerment and personal innovative behavior level.
