The biochemical study of the nutritional status of 101 healthy pregnant women and cord blood samples showed that maternal serum protein, albumin, hemoglobin (Hb), iron (Fe), zinc (Zn) and calcium (Ca) were decreased, and serum transferrin and copper (Cu) were increased in the course of gestation.Correlation coefficients and stepwise regression analysis suggested that the concentrations of serum protein, Fe, Zn, Ca,Hb were positively correlated with the intake of calories, proteins, animal foods (especially fish and meats), Ca and vitamin C.The concentration of cord blood Ca,Zn and Fe were found highly related to the maternal serum levels in the late stage of pregnancy (P

Eight parameters about iron nutrition were observed longitudinally in eighty pregnant women from the first trimester to delivery. Their nutrients intake were recorded at the same time. It was noted that serum iron store (ferritin) decreased markedly in the course of pregnancy and the incidence of iron deficiency increased. Total iron intake was closely related to the variation of these parameters, the degree of iron deficiency in pregnant women and the content of cord ferritin. Iron in maternal serum is correlated to ferritin in the cord blood. It suggested that natural food abundant in iron, or food fortified with iron should be taken in early pregnancy to prevent iron deficiency of mothers.

Objective To compare the effect of Buzhong Yiqi Decoction (BYD) containing different doses of Radix Astragali on fibulin-3 expression in the hemorrhoid tissues of stage Ⅲ internal hemorrhoids patients with spleen deficiency and sinking of qi, and to evaluate its therapeutic efficacy and possible mechanism. Methods Fifty-five qualified patients were randomly divided into control group(N = 15), Chinese medicine group 1(N =20), and Chinese medicine group 2(N=20). All of the 3 groups were treated with operation, and additionally, Chinese medicine group 1 was given BYD containing Radix Astragali 20 g, and Chinese medicine group 2 was given BYD containing Radix Astragali 50 g orally after operation. The scores of anal pendant expansion and anal prolapse were evaluated, and the expression level of fibulin-3 in the hemorrhoid tissues was detected by Western blot method. Results After treatment, the symptoms of anal pendant expansion and anal prolapse were improved in the 2 Chinese medicine groups (P < 0.05) , and the improvement of anal pendant expansion symptom in Chinese medicine group 2 was superior to that of Chinese medicine group 1(P<0.05). Compared with the control group, the expression level of fibulin-3 in the hemorrhoid tissues of the two Chinese medicine groups was increased (P < 0.05); the expression level of Chinese medicine group 2 showed an increasing trend as compared with that of Chinese medicine group 1, but the difference was statistically insignificant (P > 0.05). Conclusion BYD with large dose of Radix Astragali exerts stronger therapeutic efficacy for the treatment of prolapsed hemorrhoids than BYD with small dose of Radix Astragali, and its therapeutic mechanism has no obvious relation with promoting the increase of fibulin-3 expression.

A longitudinal study was carried out on zinc, copper, calcium, phosphorus and magnesium status of 104 normal primigravidas. The five elements in serum and hair of the mothers and their newborns were estimated with inductive coupled plasma emission spectroscopy. The results showed that the concentration of serum zinc, calcium, magnesium decreased gradually while copper and phosphorus increased remarkably in the course of pregnancy. The serum copper and phosphorus of cord blood were lower, zinc and calcium were higher than that of mothers' blood. The contents of hair zinc, copper, and phosphorus showed no differences but calcium and magnesium decreased gradually during pregnancy. Except that the level of copper in the newborns' hair was much lower, other elements were much higher than that in the mothers' hair.

Objective To study the Mycoplasma pneumoniae infection in the clinical characteristics and treatment methods. Methods From June 2008 to December 2009,49 cases of Mycoplasma pneumoniae infection in patients with clinical data were retrospectively analyzed and summarized. Results 49 cases of children were diagnosed with acute upper respiratory tract infection in 13 cases(26.5% ) ,acute bronchitis 21 cases(42.9%) ,bronchial pneumonia, 15 cases( 30.6% ). Azithromycin alone treatment group,24 cases cured 22 cases ,2 cases improved, the cure rate of 91.7% ;erythromycin and azithromycin infusion + oral sequential treatment group,25 cases recovered,21cases improved,4 cases,the cure rate was 84%. Compared with the two groups,difference was not statistically significant(P ＞ 0.05). All patients were treated in our hospital with average of 13.8d,follow-up period without recurrence.Conclusion Mycoplasma pneumoniae infection in large differences in clinical manifestations, early diagnosis and treatment should be carried out. Azithromycin in the treatment effect was good, a short course of treatment could be used as treatment of Mycoplasma pneumoniae infection.

Objective: To observe the influence of transcutaneous CO2emission (TCE) at points on the meridian or beside the meridian after different stimulations like acupuncture De-qi, sham acupuncture, study the correlation between acupuncture De-qi and local energy metabolism through TCE. Methods: Twenty healthy volunteers (male 8, female 12, average age 29 years old) were selected. Before, during and after five different acupuncture Neignan (PC 6), the TCE was measured at Quze (PC 3), point A [at the lower one fourth of line between Tianquan (PC 2) and Quze (PC 3)], point B [at the middle of line between Ximen (PC 4) and Quze (PC 3)], point C (2 cm ulnar side point A) and point D (2 cm ulnar side point B) with a high sensitive C02 instrument (Frewil-Q.F., made in China). The measure results were compared. Results: The comparison on value of TCE before and after the acupuncture, in Sham acupuncture and shallow acupuncture groups, it increased in all five points; in De-qi acupuncture group, there are significant increase on point A, point B, and Quze (PC 3), it has statistic significance, but there are no significant increase on point C and D. After Ximen (PC 4) or Daling (PC 7) were pressed to block Neiguan (PC 6), the value of TCE on Quze (PC 3), point A and point B were decreased during acupuncture Neiguan (PC 6), and increased after the block was removed, but there was no significant difference. Conclusion: Sham acupuncture has also some effects on body, it can increase energy metabolism of local skin, it may be the reason that shallow acupuncture without qi amving can obtain clinical efficacy. The operation method of traditional qi arriving acupuncture can increase energy metabolism of relevant meridian skin, mechanical press can reduce this effect.

Objective To observe the influence of different altitudes on the basic vital signs of cardiopulmonary resuscitation (CPR) rescuers before and after CPR.Methods The experiment was completed in the Simulated Cabin for Special Environment of Northwest of China. Ninety healthy adult medical staff in General Hospital of Xinjiang Command were randomly and equally divided into 3 groups: plain (normal oxygen), 3700-meter high altitude and 4300-meter high altitude. According to the 2010 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care, the values of heart rate (HR), mean arterial pressure (MAP), respiration rate (RR), arterial oxygen saturation (SpO2), before and after 1 CPR cycle were recorded for statistical analysis and their changes were compared.Results The HR and RR significantly increased (P<0.05), but MAP and SpO2 did not change significantly (P>0.05) in the three groups. The HR and RR was faster in 4300 meter high-altitude than in 3700 meter high-altitude (P<0.05), and was faster in 3700 meter high-altitude than in the plain (P<0.05). But there was no significant difference between the three groups in MAP and SpO2 (P>0.05).Conclusions With the elevation of the altitude, HR and RR may significantly increase in CPR rescuers, but there is no significant influence on MAP and SpO2.

Aim To observe the physical coupling between transient receptor potential channel vanilloid type 4 (TRPV4 ) and cPLA2 in endothelial cells. Methods We investigated the physical association of TRPV4-cPLA2 coupling by immunofluorescence reso-nance energy transfer (immuno-FRET)to assess the spatial proximity between TRPV4 and cPLA2 in human microvascular endothelial cells (HMEC),primary cul-tured endothelial cells and in thoracic aortas rings from high salt-induced hypertension mice.Results At the cellular level,with high salt treatment,the physical in-teraction of TRPV4 and cPLA2 was significantly en-hanced in primary vascular endothelial cells and HMEC.Furthermore, in thoracic aortas rings from high salt-induced hypertension mice,we found an in-creases interaction between TRPV4 and cPLA2 in en-dothelial cells from arterial segments .Conclusion High-salt treatment increases the endothelial TRPV4-cPLA2 coupling,indicating that this coupling may pro-vide a new target for vascular endothelial dysfunction.

The nutritional status, serum lipids, protein, Ca, and Zn of 85 toxemic and 42 normal pregnant women were estimated longitudinally from the first trimester to delivery. The results of dietary survey revealed that correlative and regressive relationship closely existed between serum TC, LDL-C, LDL-C/HDL-C, AI, and percentage of animal fat. In the toxemic cases, there were significant increases of serum LDL-C/HDL-C, AI, and decrease of HDL-C, HDL-C/TC and Ca in the 1st trimester as compared with those of the normal. In the 3rd trimester, there were significant increases of serum TG, TC, LDL-C, LDL-C/HDL-C, AI and MUFA, and decrease of serum HDL-C, HDL-C/TC, Ca, Zn, total protein and albumin in the toxemic cases. The regressive relationship was found between GI (ges-tosis index) and serum Ca in the 1st trimester or GI and serum P/S, A/G, LDL-C/HDL-C, AI in 3rd trimester. The problem of nutritional factors on development of toxemic cases was discussed and some nutritional suggestions were made.

The nutritional status, serum protein, albumin, calcium, zinc, iron, SF, FEP, vitamin A, activity of RBC transketolase, and blood glutathione redu-ctase of 349 normal primigravidas, 30 healthy non-pregnant women and 42 toxemic gravidas were estimated longitudinally from the 1st trimester to delivery. It was noted that serum protein, albumin, Ca, Zn, and Fe decreased markedly in the course of pregnancy. The content of serum vitamin A showed no variation or decrease in the 3rd trimester in 1/3 of the pregnant women observed. Insufficiency of thiamine and riboflavin were noted in 16.7% and 47% of the normal pregnant women respectively. The adequate nutrients intakes in pregnancy were considered to be: Energy, +200 kcal/d; Protein, + 15g/d in the 2nd trimester and +25g/d in the 3rd trimester; Calcium 1000 mg/d in the 2nd trimester and 1500mg/d in the 3rd trimester; Zinc, 20mg/d; Iron 26 or 30 mg/d by supplementation if possible; vitaminA 1000 ?gRE/d; both thiamine and riboflavin 1.8 mg/d.
