Objective To investigate the clinical efficacy of Zusanli moxibustion intervention in abdominal distention with enteral nutrition after stomach cancer surgery.Methods One hundred patients who had undergone stomach cancer surgery and received postoperative enteral nutrition were randomly allocated to treatment and control groups, 50 cases each. The control group received medication and the treatment group, Zusanli moxibustion in addition. Post-treatment incidences and grading scores of abdominal distention were compared between the two groups.Results The incidence of abdominal distention was 6.0% in the treatment group and 24.0% in the control group; there was a statistically significant difference between the two groups (P<0.05). The grading score of abdominal distention was (0.33±0.58) in the treatment group and (0.92±1.00) in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Zusanli moxibustion can effectively prevent the occurrence of abdominal distention in patients with enteral nutrition after stomach cancer surgery.

Objective Immunoreactive intensity of dopamine transporter(DAT)was quantitatively analyzed in the different regions of postmortem human brain in order to provide evidence in selecting an appropriate reference region for neuroimaging in measurement of the altered DAT.Methods The brain tissue blocks taken from 8 male cadavers were paraffin-embedded and sectioned,and immunoautoradiography was used to display the difference of DAT immunoreactive intensity in the substantia nigra,putamen and caudate nucleus,cingulate cortex,frontal cortex,occipital cortex and cerebellar cortex.Results The highest DAT density was found mainly in the substantia nigra,caudate nucleus and putamen,while the lowest density was only seen in cerebellar cortex.Quantitative analysis revealed that the intensity of DAT immunoreactivity(DAT-IR)in cerebellar cortex was respectively 1/3.50,1/3.72,1/1.28 of that in frontal cortex,cingulate cortex and occipital cortex,and it was only 1/8.33,1/11.67,1/8.56 that of substantia nigra,caudate nucleus and putamen.Conclusions The cerebellar cortex has the lowest DAT as compared to other examined brain regions,and it can be used for a reference region in neuroimaging to detect altered DAT.

The microvasculature of the rabbit right ventricle was studied by the method of vascular corrosion cast and scanning electron microscopy. In the endocardium could be seen thin and sparse capillary network i. e. subendothelial capillary network formed by the branches of the arterioles passing through myocardium. In the myocardium, arteriole and its branches distributed in certain area. Sphincters could be seen in the beginning of the arterioles. Capillaries of the papillary muscle in right ventricle were parallel to muscle bundle and were thinner and sparser than those of the papillary muscle in left ventricle. Venous system in right ventricle wall was similar in architecture to that in left ventricle, postcapillary venule joined its corresponding venule in a "turnip root" like pattern. No A-V anastomosis could be seen, yet thebesian vessels and myocardial sinusoids directly opened into ventrical chamber could be found.

Anopheles minimus was infected with Plasmodium yoelii yoelii under adequate condition. The malaria parasite could develop normally and produce mature oocysts containing sporozoites. Large numbers of free active sporozoites were found in the haemocele but most of them failed to penetrate into the mosquito's salivary glands. Thus the sporogonic cycle of the parasite could not be completed.But in one mosquito, a few sporozoites were found in its salivary glands. It seems that there is an individual difference in the susceptibility of the mosquitoes and this throws some light on the possibility of selecting a susceptible strain of A. minimus to establish the A. minimus-P. yoelii system for malaria research.

By analyzing the crisis of survival in 2 hospitals, the authors argue that reform of the hospital property right system may be a way out. However, in the process of the reform, hospitals may face some problems. One problem is how to ensure the steady transition and sustained development of a hospital if the whole of it is sold out to an enterprise run by the local people. Another problem is how to safeguard the status, salary and welfare of the staff. To ensure the success of the reform, the following measures need to be taken: ①strengthening leadership, seeking unity of thinking, and clarifying the guiding ideology; ②formulating rigorous and detailed plans so as to guarantee a steady transition; ③making proper arrangements for the placement of the staff after the change of the property right system so as to ensure the ideological stability of the staff.

This study was aimed to establish the ultra high performance liquid chromatography (UHPLC) fingerprints of Psoralea corylifolia L. The separation was achieved on a Shim-pack XR-ODS Ⅲ column (50 mm í 2.0 mm, 1.6μm) by gradient elution with acetonitrile-0.2% glacial acetic acid solution as the mobile phase. The flow rate was 0.1 mL·min-1 and the measurement wavelength was 246 nm. The temperature of the column was 45oC. The results showed that the UHPLC fingerprint of P. corylifolia L. was established and 10 characteristic common peaks were found, among which 6 peaks were recognized by comparing with reference substances. It was concluded that the method was rapid, reliable and reproducible. The established fingerprint can provide references for the study of sub-stance basis and quality control of P. c orylifolia L.

A 74-year-old man presented with yellowish red nodules and plaques on the trunk for more than one year.Physical examination showed more than 20 scattered,irregularly shaped,well-demarcated,yellowish red nodules and plaques measuring 0.5-15 cm in diameter on the trunk.The plaques on the right lower abdomen showed central ulceration and atrophy with scar formation.Plasma protein electrophoresis revealed that the levels of immunoglobulin G (IgG) and kappa light chain were 18.3 g/L and 20.70 g/L respectively.Histopathologically,large necrobiotic areas and granuloma were observed alternately in the dermis and subcutis.There were numerous Touton giant cells,foreign body giant cells and foamy histiocytes in the granuloma,and many cholesterol clefts were found in the center of necrobiotic areas with the formation of lymphoid follicles in some regions.Both eyes of the patient were involved to different degrees.He was diagnosed as necrobiotic xanthogranuloma with IgG kappa paraproteinemia and eve involvement.

Objective To explore the effect of dexmedetomidine on hemodynamics in hypertensive patients undergoing thyroid surgery with local anesthesia.Methods Sixty patients with preoperatively diagnosed class Ⅰ to Ⅱ hypertension undergoing selective thyroidectomy were randomly divided into D (dexmedetomidine) and M (midazolam) groups (30 patients in each group).Doses of dexmedetomidine 0.5 μg/kg were finished in 20 minutes injection in patients of D group before the start of the surgery,then sequentially maintained at the rate of 0.1 ～ 0.5 μg/ (kg · h) with decreasing speed of 0.1 μg/(kg · h) when systolic pressure kept down to 110 mmHg or heart rare down to 60 bpm or Ramsay score of 3 points.The patients in M group were injected with midazolam 0.04 mg/kg 20 minutes before the start of surgery,then maintained at the rate of 0.02 ～ 0.05 mg/(kg · h),decreasing speed of 0.1 mg/(kg · h) to keep Ramsay score of 3 points if necessary.Two groups of patients with Ramsay score of 3 points but a high blood pressure (higher than 30％ of basic level) or heart rate (more than 100 bpm) were treated with drugs during operation.Record the systolic pressure,diastolic pressure,heart rate and Ramsay score at the time of before medication (T0),the injection of local anesthetics (T1),the start of surgery (T2),pain compliments required additional local anesthetics (T3),dealing with gland (T4) and the end of surgery,VAS in 8 h after operation and adverse reaction were recorded.Results In D group,the dosages of urapidil and esmolol [(10 ±5)mg and (0 ±0)mg] were significantly less than those in patients of M group [(60 ± 10) mg and (80 ±5) mg,t =14.82,t =19.78,P ＜ 0.05].Blood pressure and heart rate were all significantly decreased at the time of T1,T2 and T5 when comparing with T0(P ＜0.05 orP ＜0.01),and only heart rate was significantly decreased at the time of T3 and T4 (P ＜ 0.05).While in M group,blood pressure and heart rate were higher than basic levels at the time of T3 and T4 (P ＜ 0.05).Besides,lower blood pressure and heart rate were less than those in M group at all observed time expect T0 (P ＜ 0.05).Conclusions Good sedation effects can be produced by both dexmedetomidine and midazolam in hypertensive patients undergoing thyroid surgery with local anesthesia,but dexmedetomidine was determined more suitable in sedation and anti-hypertension in patients with light to moderate hypertension for better hemodynamic stability effect with local anesthesia.

Objective To study the altered expression of dopamine transporter (DAT) in substantia nigra and striatum in postmortem human brain of Parkinson’s disease (PD). Methods Immunoautoradiography was used to reveal DAT distribution in postmortem human brain. Results Strongly labeling signal of DAT was mainly found in the substantia nigra, the putamen and the caudate nucleus in controls. In contrast, it was drastically reduced in the putmen and the dorsolateral caudate nuclus in PD brains, but the ventromedial part of the caudate nucleus showed a significant sparing adjacent to the border of the lateral ventricle. In the substantia nigra, the ventral and the lateral parts of the substantia nigra showed an obvious decreasing of DAT and the reducing degree of DAT labeling signals in those regions is smaller than that in the putamen and the caudate nucleus. Quantitative analysis revealed that 90.9% and 66.7% of the labeling intensity of DAT were decreased in the putamen and the caudate nucleus as comparing with the corresponding controls respectively (P
