[Objective] To further study tanshinone role in intestinal barrier dysfunction in sepsis. [Methods] Mainly refer to nearly a decade at home and abroad on tanshinone pharmacological effects, and tanshinone in sepsis, especially the impact on the intestinal barrier dysfunction. [Results] Tanshinone in sepsis, and heart head blood-vessel, anti-tumor and so on in the field of study is more, but improving sepsis of intestinal barrier function in aspects of the study is less, but through tanshinone antibacterial anti-inflammatory, antioxidant, anti platelet aggregation, improve microcirculation, regulate immune function, this paper expounds tanshinone improving sepsis, possible mechanisms of intestinal barrier function. [Conclusion] Tanshinone can improve sepsis pathophysiological process, ischemia oxygen to the tissues and organs and whole body strong inflammatory reaction factors such as the cause of intestinal barrier function is impaired, but for its specific mechanism, further research is needed.

Objective To systematically evaluate the value of narrow band imaging(NBI)and iodine staining in early diagnosis of esophageal cancer and precancerous lesions.Methods The databases of PubMed,Embase,CNKI,VIP technological journals and Wanfang digital journals were retrieved by computer for searching the literatures on the value of NBI and iodine staining in diagnosing early esophageal cancer and precancerous lesions.The Meta-Disc 1.4 software was used to conduct the meta analysis and calculate the pooled sensitivity,specificity and 95％ confidence interval(95％ CI).Summary receiver operating characteristic(SROC)curve was drawn and the area under curve(AUC)was calculated,thus the diagnostic values of the two methods were evaluated.Results Totally 13 articles were included,including 975 patients.The pooled sensitivity and specificity for NBI were 0.88(95％CI=0.86 to 0.90)and 0.79(95％CI=0.76 to 0.82).The pooled sensitivity and specificity for iodine staining were 0.95(95％CI=0.93 to 0.97)and 0.45(95％CI=0.40 to 0.49).AUC of SROC for the two methods were 0.938 6 and 0.952 9 respectively.There was no statistically difference in the AUC values between the two methods(Z=0.519,P>0.05).Conclusion NBI and iodine staining are both effective ways in the diagnosis of early esophageal cancer and precancerous lesions.And both of them have a certain clinical value.

Nowadays, it is necessary to emphasize the three basic inseparable elements in the treatment of severe burn infection, which are systemic care, burn wound care, and rational use of antimicrobials topically or systematically. Systemic care has been shifted from simple nutritional support to maintaining the systemic homeostasis, including balancing immune-inflammatory response, and protecting organs from dysfunction. Some work focused on regulating systemic immune response in the initial phase and the balance of inflammatory response after occurrence of severe burn infection have been reported. These results at least broaden our thinking to recognize that treatment should not only destroy microbes, but also balance the response of the body. Escharectomy in earlier phase has been a consensus. Currently, we turn our vision into how to use "damage control surgery (DCS)" concept in management of severe burn. DCS in burn care includes the evaluation of perioperative situation more accurate to make a more appropriate surgical decision. Meanwhile, an overall strategy should be established to confront the rapidly increasing drug resistance of the pathogens. The release of endotoxin after use of antimicrobials, which has been studied widely, should be explored further.

Objective To explore the effects of cognitive behavioral intervention in psychological nursing of young female patients with facial burn.Methods 64 cases of young women patients with facial bum were selected as the research object,and randomly divided into the observation group and the control group,with 32 cases in each group.The observation group was given the cognitive behavioral intervention and the control group was done by conventional nursing methods.The anxiety and depression scores between the two groups before and after the intervention were compared.Results After injury,the anxiety and depression scores of both the observation group and the control group were higher than those of the domestic norm; the anxiety and depression scores between two groups showed no statistic significance before intervention,and after intervention,the anxiety and depression scores between two groups had significant difference,scores of the observation group were lower than those of the control group.Conclusions Cognitive behavioral intervention can reduce anxiety and depression of young female patients with facial burn.It is a kind of effective psychological nursing method,and worthy of clinical promotion.

Objective To investigate the expression of miR-200b in lung cancer and its relationship with clinicopathological features of lung cancer.Methods The specimens of lung tumor tissue and adjacent normal lung tissue of 36 cases of lung cancer who received surgical treatment in our department were collected,and then quantitative real time PCR (qRT-PCR) was applied to determine the expression of miR-200b in lung cancer tissue and adjacent normal lung tissue.Results The expression of miR-200b in lung cancer was significantly lower than adjacent normal lung tissue (P =0.000),and in small cell lung cancer was also significantly lower than adenocarcinoma and squamous cell carcinoma (0.13 ± 0.09 vs.0.64 ± 0.33,0.75 ± 0.30) (P =0.005 and P =0.001).The expression of miR-200b in patients with positive lymph nodes,advanced stage of lung cancer and in smokers were significantly lower than those with negative lymph nodes,early stage of lung cancer and in non-smokers,respectively (0.52 ± 0.29 vs.0.87 ± 0.35,0.46 ±0.25 vs.0.90 ±0.32,0.52 ±0.27 vs.0.90 ±0.39) (P =0.004,P =0.000 and P =0.015).Conclusions Low expression of miR-200b may participate in the occurrence and progression of lung cancer,especially in small cell lung cancer,and correlates with the metastasis of lung cancer.The down-regulated expression of miR-200b may be induced by smoking.Thus,miR-200b perhaps is a new target for the treatment of lung cancer.

Objective To study the correlative risk factors of uterine cavity adhesion (UCA),and observe the clinical efficacy of hysteroscope operation treatment of UCA.Methods According to whether the occurrence of UCA,120 patients with spontaneous abortion were divided into two groups.The correlative risk factors of UCA were analyzed by multiple factors regression analysis.The patients with UCA were treated with hysteroscope operation treatment,and the clinical efficacy were observed.Results In 120 patients with spontaneous abortion,46 patients (38.3％) had UCA.Single factor analysis result showed:UCA was correlated with pelvic inflammation,gravidity,uterine cavity suction negative pressure,uterine cavity suction time (P ＜ 0.05),but UCA was not correlated with age,years of education,occupation,gestational weeks,menarche age (P＞ 0.05).Multiple factors analysis result showed:UCA was correlated with pelvic inflammation,uterine cavity suction negative pressure,uterine cavity suction time (P ＜ 0.05).The total effective rates of hysteroscope operation treatment of mild,moderate and severe UCA were 100.0％ (18/18),93.8％ (15/16)and 83.3％ (10/12) respectively,there was no significant difference among them (P ＞ 0.05).Conclusions Along with the increasing of uterine cavity suction negative pressure and extension of uterine cavity suction time,the risk of UCA is also increasing,pelvic inflammation is also an independent risk factor of UCA.Hysteroscope operation treatment of UCA has better curative effect,especially for mild UCA,it is worth clinical application.

Objective To study the effects of self- edited doggerel on health education of senile AIDS patients in northern Guangxi region, in order to seek a suitable and effective way for the senile AIDS patients' health education. Methods 200 senile patients who were inpatients in dermatological department and examinees in the center of health examination of our hospital were randomly divided into the experimental group and the control group from August to December in 2009, 100 cases in each group, the experimental group was educated by a method of adopting a self-edited doggerel, the control group was educated by traditional way including manual + video or a series of special lectures, Two groups were carried out questionnaire survey designed by ourselves before and after the education during a period of a week and then evaluated the effects of health education. Results Compared with the rate before adopting self-edited doggerel, the knowing rate of AIDS and regulations of the experimental group was above 90%,there was a significant increase; and compared with the control group, the rate was also higher than the latter. The behaviors and attitudes of the experimental group had a significant positive improvement, but showed no significant difference between the two groups. Conclusions The doggerel is humorous, rhyming, simple and easy-going, it is so user-friendly, easy to understand and to remember that it is a suitable and effective way for the health education of senile AIDS patients.

Objective To explore the molecular mechanism of S100A9-induced secretion of vascular endothelial growth factor-A (VEGF-A)by monocytes.Methods Peripheral blood specimen were collected from healthy individuals undergoing physical exami-nation and the CD14 + monocytes were purified by using immunomagnetic beads and the expression of the receptor for advanced gly-cation endproducts (RAGE)was detected by flow cytomertry.In vitro CD14 + monocytes were stimulated by S100A9,and anti-RAGE antibody or NK-κB signal pathway inhibitor were pre-incubated for 1 hour and then stimulated by S100A9,the levels of VEGF-A were detected by using enzyme-linked immunosorbent assay.Results The high level of RAGE was expressed by isolated CD14 + monocytes,after S100A9 stimulation,the secretion of VEGF-A by CD14 + monocytes was significantly increased in a dose and time dependent manner.However,the inducing VEGF-A was significantly decreased(P <0.01 ),while pre-treated with anti-RAGE antibody or NK-κB inhibitor (P <0.01).Conclusion S100A9 inducing the secretion of VEGF-A by monocytes and is de-pended on RAGE-NK-κB signal pathway,suggesting that S100A9 might promote angiogenesis.

BACKGROUND: Nowadays, it is reported that vessel structural abnormity is the main morphological basis of vertigo due to vertebrobasilar arterial insufficiency abroad, but the report of vascular structural abnormality in vertebrobasilar arterial insufficiency is rare at home.OBJECTIVE: To observe the manifestation and clinical significance of vessel structural abnormity tested by digital substraction angiography (DSA)in patients with vertigo induced by vertebrobasilar arterial insufficiency.DESIGN: Case analysis.SETTING: Department of Neurology, Wuxi Second Hospital (Wuxi Municipal Second People's Hospital) Affiliated to Nanjing Medical University and Department of Neurology, Huaihua Hospital Affiliated to Nanhua University.PARTICIPANTS: A total of 57 patients, who were diagnosed as having episodic vertigo with or without nausea or vomiting, and hospitalized in the Department of Neurology, Huaihua Hospital Affiliated to Nanhua University from August 2003 to May 2004 and Wuxi Second Hospital (Wuxi Municipal Second People's Hospital) Affiliated to Nanjing Medical University between October 2004 and May 2005, were enrolled.METHODS: Fifty-seven patients with vertigo induced by vertebrobasilar arterial insufficiency hospitalized in the recent two years were treated with digital subtraction radiography in aortic arch and aortocranial angiography:Applying retrograde angiography of femoral artery puncture, Optiray nonionic contrast agent with syringe pattern to perform aortic arch angiography. Digital subtraction machine displayed bilateral carotid artery, vertebral artery, ranged from carotid artery to siphon of carotid artery from multiple angles. Measurement and evaluation were conducted by 2 doctors from department of neurology.MAIN OUTCOME MEASURES: Type, distribution and proportion of vesselstructural abnormity of aortic arch, carotid artery and vertebrobasilar system.RESULTS: Of the 57 patients, 1 patient was dropped out, because the left vertebral artery (LVA) could not be entered. A large area cerebral infarction was occurred in another patients during aortic arch angiography was performed, and the operation was stopped. Totally 55 patients were involved in the result analysis. It was found that 71%(39/55) of patients had vessel structural abnormity in cervical part and intracalvarium, 11%(6/55)of patients with simple anterior circulation lesion, 60% (33/55) of patients with posterior circulation lesion, of which 9 cases (16%) with compound lesion of anterior circulation abnormity. Two or above vessels in 24 cases (24/55,44%) were involved. Vertebral artery complicated with other angiostegnosis was the most common, and there was no vessel structural abnormity in other 16 cases (16/55,29%).CONCLUSION: Various types of vessel structural abnormity are the main etiological factors of vertigo induced by vertebrobasilar arterial insufficiency. Gold standard of diagnosing vertigo due to vertebrobasilar arterial insufficiency is DSA.
