In order to provide insights into sampling in suspected cases of morphine poisoning,the present study was conducted to investigate the distribution patterns of morphine in organs in rats with acute morphine poisoning at different post mortem intervals.Localization and semi quantitation of morphine in the brain,kidney,heart and liver were determined in rats at 15min to 5h after intravenous administration of morphine and at different intervals from 0 to 48h after death using the immunohistochemical SP method and image analysis.The results showed that the morphine could be detected in cytoplasms of certain parenchymal cells in all organs examined short time after delivery of morphine.With the extension of post delivery intervals,the level of morphine inereased,peaked,followed by decrease thereafter.The amount and the distribution patterns of morphine varied greatly with different organs.In the brain,the morphine could be detected earlier than in the heart,kidney and liver.It could detected 15min after the drug administration,with a peak,and disppeared at 5h after drug delivery.It decayed slowly as compared with the heart and lung.The kidney was the second organ in which the morphine was detected early with a high level and decayed slowly.In conclusion,immunohistochemical SP method can be used as a specific technique to detect morphine in organs in suspected cases of morphine poisoning.Both brain and kidney were the candidates for sampling in such case.

Background It is very important for us to understand retinal function change in the patient with diabetic mellitus in clinic. At present,the study about diabetic mellitus associated with macular edema includes fundus fluorescense angiography ( FFA) and multifocal electroretinogram ( mfERG) etc.. However, seldom research is performed in the mfERG findings for different types of diabetic macular edema. Objective This study aimed to investigate the mfERG change in different types of diabetic macular edema compared with normal population. Methods Fifty-seven eyes with diabetic macular edema from 40 patients and 35 eyes from age-and gender-matched normal subjects were enrolled in this study. The eyes with diabetic macular edema were assigned to local macular edema group (n=16) ,diffuse macular edema group (n = 22) and cystoid macular edema ( n = 17 ) based on the manifestation of FFA. MfERG was recorded in all the individuals. The informed consent was obtained from each subject prior to any the medical examination. Results In focal diabetic macular edema group,the response density of P1 wave was significantly attenuated in ring 1 , showing a statistical difference in comparison with controls (t =2. 170,P = 0.038) ,and the latencies of P1 and N1 waves showed obvious prolong in ring 4 and 5 (t = 2.519,P = 0. 017 ;t = 2. 451 ,P = 0. 020). In diffuse diabetic macular edema group,the response densities of P1 and N1 waves were declined in ring 1,3,5 and ring 1,3,4,5 respectively,and the latencies of P, in ring 3,4 were significantly delayed respectively in comparison with controls (all P < 0. 05 ). In cystoid diabetic macular edema group, the response densities of P1 and N1 waves were lowed from ring 1 through 5 respectively, and the latencies of P1 and N1 waves were significantly longer from ring 3 through 5 and ring 4 respectively with the statistically significant difference from controls (all P<0. 05). The visual function of fovea was badly damaged. Conclusion These studies indicate that the most serious damage of visual function is in foveal area in cystoid diabetic macular edema group, and is then parafoveal area of diffuse diabetic macular edema group and perifoveal area in focal diabetic macular edema group. The outcome of mfERG presents a good consistency with FFA findings in the patients with diabetic macular edema.

Objective To observe the clinical efficacy of treatment of chronic pelvic inflammatory disease with Kangfu Xiaoyan suppository combined ceftriaxone.Methods84 cases of chronic pelvic inflammatory disease in our hospital from June 2015 to August 2016 were randomly divided into observation group and control group, with 42 cases in each group.The control group were treated with ceftriaxone sodium alone,on the basis of the control group, the observation group was treated with Kangfu Xiaoyan suppository.After treatment, the changes tumor necrosis factor-α (TNF-α), transforming growth factor β1 (TGF-β1), interleukin 8,1β (IL-8, IL-1β) and clinical symptom score in the two groups were recorded and analyzed.Results①After two weeks of treatment, the total effective rate of observation group was 92.86%, significantly higher than that of the control group(76.19%), and the difference was statistically significant (P<0.05).②After treatment,the levels of TNF-α, TGF-β1 in the observation group[(0.80±0.23)μg/L, (12.43±1.98)μg/mL) were better than the control group[(1.81±0.35)μg/L,(19.01±2.24)μg/mL], and the differences were statistically significant (P<0.05);③After treatment,the abdominal pain, vaginal symptom score of observation group[(1.57±0.11),(1.45±0.15) points] were lower than the control group[(2.05±0.17),(2.16±0.20) points], and the differences were statistically significant (P<0.05).ConclusionKangfute Xiaoyan Suppository combined with ceftriaxone sodium in the treatment of chronic pelvic inflammatory disease, curative effect is exact, compared with the single application of ceftriaxone sodium in the treatment without obvious adverse reactions, can effectively improve the symptoms of patients with chronic pelvic inflammatory disease, it is worthy of further research and application.

Objective To observe the effects of Bushen Huoxue Decoction on clinical symptom, vertigo degree and cognitive function for elderly patients with chronic cerebral circulation insufficiency (CCCI); To explore its possible mechanism. Methods Totally 70 cases were randomly divided into observation group and control group according to the random digits table method, with 35 cases in each group. The two groups were given Western medicine consisting of blood pressure control, glucose control and blood lipid control. Based on this, the control group was given Flunarizine Hydrochloride capsules, 5 mg once a day orally before sleeping. The observation group was given Bushen Huoxue Decoction, one dose a day and taken twice a day. The treatment lasted for 30 days. The TCM symptom score, Chinese version of dizziness handicap inventory (DHI) and Montreal cognitive assessment (MoCA) score were observed. The mean blood flow velocity (Vm) of basilar artery (BA), bilateral vertebral artery (VA), bilateral middle cerebral artery (MCA) and the content of plasma acid phospholipid (AP) were detected, and the clinical efficacy was evaluated. Results The total effective rate of the observation group was 94.3％ (33/35), which was significantly higher than that of 82.9％ (29/35) in the control group, with statistical significance (P<0.05); after treatment, the TCM symptom score, DHI score, and the content of plasma AP were significantly lower than those of pre-treatment in the same group (P<0.05); the MoCA score and the Vm of VA, LBA, RBA, LMCA, RMCV were significantly higher than those of pre-treatment in the same group (P<0.05); the TCM symptom score, DHI score, MoCA score, the Vm of LVA, LMCA, RMCA and the content of plasma AP in the observation group were improved better than those in the control group, with statistical significance (P<0.05). Conclusion Bushen Huoxue Decoction has an obvious therapeutic effects for elderly patients with CCCI, which can improve clinical symptom, vertigo degree and cognitive level, which possible mechanism is related to increasing the cerebral blood flow velocity and reducing the content of plasma AP.

Objective To investigate the protective effects of pulmonary surfactant (PS) in lung transplantation.Methods Forty-eight rabbits were divided into control group (group C),PS1 group,and PS2 group. Rabbit lungs were harvested and preserved at 4 ℃ for 6 h before transplantation. The PS1 group received 100 mg /kg of intratracheal PS before reperfusion,while the PS2 group received the same dosage PS before preservation. Using the hetero-heart-lung transplantation model,pulmonary graft function and airway compliance was assessed every 30 min for 3 h when the model was transformed into self-working state. After finishing the observation,the tissue specimens were taken for analysis of wet/dry ratio (W/D),the contents of malondialdehyde (MDA) and myeloperioxidase (MPO). All values were compared to the control group.Results The two groups treated with PS showed better airway compliance and higher PaO 2 and lower PaCO 2 than group C ( P

Objective To investigate knowledge, attitude, and practice of exercise for post-operative breast cancer. Methods 110 postoperative breast cancers were investigated using a self-designed questionnaire which included general condition of patients, knowledge, attitude and practice of exercise after breast surgery. Results The rate of effective response was 98%. The average rate of awareness about postoperative exercise for breast cancers was 87%, and the score of knowledge of intensity and forms of exercise was the lowest, while the announcements of post-operative exercise was the highest. All of the patients presented positive attitude toward exercise, however, some of them indicated that they couldn't insist on it. 41% exercised only in one form, 78% at a low intensity, 41% less than 3 times per week, and 74% at least 30 minutes per session. Only 7% did traditional Chinese medical exercise. Time after surgery correlated positively to general scores (r=0.40, P<0.01), kinds of exercise (r=0.41, P<0.05) and intensity of exercise (r=0.43, P<0.05). Phase of cancer correlated negatively to general scores (r=-0.37, P<0.05) and exercise time (r=-0.38, P<0.05). Conclusion The knowledge on intensity and form of exercise after operation is not popular in post-operative breast cancers.

To clarify the origin and development of the traditional Chinese medicine "Duhuo" and "Qianghuo" with medicinal literatures. Medical literatures of past dynasties were analysed and combined with the modern material. The "Duhuo" in Herbal writing Shen Nong Ben Cao Jing include traditional Chinese medicine "Duhuo" and "Qianghuo", "Qianghuo" was separated from "Duhuo" due to the distinguish of clinical application. The origin of "Qianghuo" is Notopterygium incisum and N. forbesii, However, The origin of "Duhuo" is very complex, Angelica pubescens f. biserrata as authentic "Duhuo" was used from Song Dynasty. "Qianghuo" was originated from "Duhuo".
