Objective To analyze the features of normal high-frequency ultrasonography of tarsal tunnel. Methods Forty volunteers (20 males and 20 females) were examined with high-frequency ultrasound (12 MHz). The tendons,nerve and blood vessels in tarsal tunnel were observed from short-axis and long-axis views dynamically. The areas of tarsal tunnel and posterior tibial nerve were measured and com-pared between the males and females. Results High-frequency ultrasonography depicted the anatomical structure of tarsal tunnel,and the tendons,nerve and blood vessels presented different sonographic features that were easy to differentiate. The area of tarsal tunnel: male (7.61 ±1.00) cm2,female (6. 61 ± 1. 07) cm2 (P <0. 01). The area of posterior tibial nerve: male (9. 59 ± 0. 75) mm2,female (8.91 ±0.74) mm2(P<0.01). Conclusion High-frequency ultrasonography can clearly show and accurately measure the tarsal tunnel structure. To be familiar with the normal ultrasonographic anatomy of tarsal tunnel will help to improve the efficacy of ultrasound diagnosis of tarsal tunnel abnormalities.

Research team shows virtual and distributed characteristics in the big science era.It is common and frequent that researcher often communicates with each other informally for knowledge sharing regularly or non-regularly.Thus raised the attention paid by research administrators to such informal communication in the research team.From the aspect of community practice,we tried to propose helpful suggestions and considerations to improve the effectiveness of informal communication from following four perspectives:focusing on the informal social network in research team,create conditions for informal communication,train communication coordinators and measure the values of informal communication scientifically.

Obesity often results when regular caloric intake exceeds the energy expenditure. Hypothalamus is the center that regulates feeding and energy balance inside the body, especially the lateral hypothalamic area (LHA) and ventromedial nucleus (VMN). Acupuncture-moxibustion has achieved significant progress in treating simple obesity, and the relevant studies have revealed the central action mechanism underlying the treatment. By reviewing the literatures associated with the mechanism studies on acupuncture-moxibustion for simple obesity, this article is going to provide clinical and scientific guidance for the treatment of simple obesity with acupuncture-moxibustion.

Objective To evaluate whether estradiol can inhibit and cure the inflammation of experimental preeclampsia in rats. Methods Experimental preeclampsia was induced in 14-day-pregnant rats by infusion of endotoxin (1.0 ?g/kg). Rats with normal pregnancy were infused with sodium chloride solution.A group of preeclampsia rats was injected with 17?-estradiol (17?-E_2, 1 mg?kg -1 ?d -1 ). Blood pressure, albuminuria,inflammation associated adhesion molecule CD_ 49d and tumor necrosis factor-?(TNF-?) were assessed. Results On pregnant day 19, for normal pregnancy group(group C) the blood pressure was (120.4?2.0)mm Hg (1 mm Hg=0.133 kPa),urinary protein (0.47?0.06)mg/24 hours;for experimental preeclampsia group(group A) blood pressure was (134.2?2.4) mm Hg,urinary protein(0.79?0.10)mg/24 hours; for experimental preeclampsia with 17?-E_2 treatment group (group B) blood pressure was(123.3?1.7)mm Hg,urinary protein (0.51?0.08)mg/24 hours. A significant increase of blood pressure and urinary albumin was observed in group A. CD_ 49d expression and TNF-? concentration were also increased. 17?-E_2 reduced the expression of CD_ 49d , concentration of TNF-?,blood pressure and albuminuria of experimental preeclampsia. However, the weight of fetuses in 17?-E_2 treatment group were less than that in other groups. Conclusion 17?-E_2 can improve the symptoms of experimental preeclampsia,but its effects on fetus need to be further studied.

Objective To analyze the changes of splenic volume and blood flow detected by ultrasonography in men having been migra-ted in high-altitude area for 10 years and to explore the relationship between the splenic blood flow and volume. Methods Men migrating to high-altitude area for 10 years,male indigenous Tibetan and healthy men from planitia with 55 cases in each were involved. Ultrasonography was performed to measure the length,width and thickness of spleen to calculate the volume,and color Doppler flow imaging was applied to measure the diameter of splenic artery and the mean flow velocity to calculate the blood flow volume. The differences among groups were com-pared and the relationship between the blood flow and the volume was analyzed. Results The blood flow and the volume of spleen in men migrating to high-altitude area were higher than those in male indigenous Tibetan and healthy men from planitia (P<0. 01),and the blood flow was positively correlated with the splenic volume (r=0. 828,P<0. 01). Conclusion The splenic volume and blood flow are increased in men when have been migrated in high-altitude area for 10 years and ultrasonography is of great importance in detecting the pathophysiologic changes in high-altitude area in our country.

Objective: To observe the effect of Tongluo Jiunao oral solution on learning and memory and the expression of AChE in hippocampus of AD rats induced by ?-amyloid1-40.Methods: 140 SD rats were divided into blank control group(normal group),pseudo-operation control group,negtive control group(model group),positive control group and experiment group(48、24、12mg?kg-1?d-1)at random.The model of AD were established by injecting ?-amyloid1-40 into bilateral hippocampus.After 4 weeks,Morris Water Maze was used to determine the ability of learning and memory.Immunohistochemical method and image analysis techniques were used to determine the expression of AChE in Hippocampus.Results: Compared with normal group,in place navigation test,the mean escape latencies of the model group increased obviously,and in spatial probe test,the frequency of passing through the platform of the model group decreased obviously(P

Objective To observe the efficacy of Zheng’s “gold hook fishing acupuncture” in the treatment of scapulohumeral periarthritis. Methods Sixty patients were randomly divided into gold hook fishing group and reinforcing-reducing group, with 30 cases in each group. Gold hook fishing group chose the main points from the Tianzong (SI11), Bingfeng (SI12), Jiajixue (double EX-B2), Binao (LI14), Jianyu (LI15), Jianliao (SJ14), Jianzhen (SI9), Ashi, Naoshu (SI10), Quchi (LI11), Waiguan (SJ5), Hegu (LI4), Houxi (SI3), Tiaokou (ST38) and Chengshan (BL57). Needles were pierced at tendon junction points and Ashi points, and golden hook fishing acupuncture was operated. Other points were given reinforcing-reducing method. The reinforcing-reducing group was treated with reinforcing-reducing method at points the same as gold hook fishing group. Patients were treated once a day for 2 courses, 5 days as a treatment course. The pain visual analogue scale (VAS), shoulder range of motion (ROM), and ability of daily life (ADL) were observed before and after treatment to evaluate the clinical efficacy. Results The total effective rate of gold hook fishing group was 90.0% (27/30), better than the reinforcing-reducing group 83.3% (25/30, P<0.05); VAS pain score, ROM score and ADL score before and after treatment in the two groups were improved to some extent (P<0.05), and scores in the golden hook fishing group were improved more significantly compared with reinforcing-reducing group (P<0.05). Conclusion Zheng’s gold hook fishing acupuncture can effectively improve the clinical symptoms and signs of patients with scapulohumeral periarthritis and their life quality.

‘Warming-dredging needling technique’ is one of the specific needling techniques created by Prof. Zheng Kui-shan for treating intractable and difficult diseases. Developed from ‘Shao Shan Huo (Mountain-burning Fire)’ and ‘warming- reinforcing method’, this method displays the effects of ‘warming’, ‘dredging’ and ‘reinforcing’. The ‘scapula-penetrating heat’ and ‘eye-transmitting heat’ belong to the representative needling techniques of ‘warming-dredging needling technique’. In order to promote the clinical application of ‘warming-dredging needling technique’, its theoretical foundation and clinical experience are summarized.
