Objective To analyze the clinical,endocrinal and genetic features of 46,XX male syndrome. Methods Retrospectively collect and analyze the clinical data of 4 cases of 46,XX male sex reversal syndrome. Results Four patients were all sociopsychologically males.Among them,2 cases had cryptorchidism,3 hypospadia and 1 severe chordee with short urethra.Neither ovary nor uterus was detected through B ultrasonography or surgical exploration.Assessment of serum sex hormone suggested hypergonadotropic hypogonadism.Genetic detection indicated 46,XX karyotype as normal female's type. Conclusions 46,XX male has nearly normal male phenotype otherwise with testes dysgenesis and most are infertile.The target of treatment is to correct the urinogenital malformation and to compensate hormone defect with androgen.

BACKGROUND: Growth factor can promote the development of collateral vessels. The synergistic effects of multiple factors are obvious. Many kinds of growth factors are enriched in bone marrow serum. OBJECTIVE: To determine effects of bone marrow serum on angiogenesis in chick chorioallantoic membranes following vascular intimal injury. METHODS: A total of 70 fertilized chick eggs were incubated at (37.5±0.5) ℃ and made a window in every egg at day 7. The survival chick embryos were randomly divided into six groups: normal saline group, normal blood serum group, normal bone marrow serum group, blood serum of rabbit suffered with vascular intimal injury group, bone marrow serum of rabbit suffered with vascular intimal injury group and vascular endothelial growth factor group (n=10), which were respectively treated with 5 μL rabbit normal blood serum, 5 μL rabbit normal bone marrow serum, 5 μL blood serum of rabbit suffered with vascular intimal injury, 5 μL bone marrow serum of rabbit suffered with vascular intimal injury, 5 μL normal saline and 0.3 μg vascular endothelial growth factor in chick chorioallantoic membranes, for 3 consecutive days. Pictures were taken by a digital camera, and the total number of the vessels around the disc was measured. RESULTS AND CONCLUSION: The total numbers of vessels in normal bone marrow serum group and blood serum of rabbit suffered with vascular intimal injury group were obviously higher than that of normal blood serum group. Large and middle vessels were obviously proliferated. Large and middle vessels were more observed in the blood serum of rabbit suffered with vascular intimal injury group. These indicated that normal bone marrow serum can stimulate angiogenesis in models of chick chorioallantoic membranes. Compared with vascular endothelial growth factor, both the normal bone serum and the bone marrow serum of rabbit suffered from vascular intimal injury were more effective in angiogenesis. The blood serum and bone marrow serum from vascular intimal injured rabbit at day 7 can significantly promote angiogenesis in chick chorioallantoic membranes, which was better than the vascular endothelial growth factor group.

34 medical college students and 26 patients with primary hypertension were served as the subjects on low sodium salt diet for 4 weeks. Before and after the experiment, serum and urinary sodium and potassium, as well as blood presure, pulse rate, and body weight were measured. During the testing period, calorie and protein were supplied sufficiently and the salt content in their common diet taken was restricted strictly. The results showed that the serum sodium decreased, potassium increased at the end of the experiment, but the changes were all within the physiological permissible limits. On the contrary, urinary sodium increased, potassium decreased and the Na/K dropped markedly, body weight increased slightly in healthy subjects and decreased by 1.0-3.0kg in patients with hypertension. The blood pressure, both systolic and diastolic, was decreased but no change in the pulse rate was observed.It was obvious that in the subjects on common salt diet, the body sodium was high and potassium low, otherwise on low sodium salt diet, such situation might be improved, and the high blood pressure could also be ameliorated in the type Ⅰ and Ⅱ of hypertension.

Lactoferrin (Lf) is one of the food protein belonged to the innate immune system. Apart from its main biological function of binding and transport of iron ions, lactoferrin also has many other functions and properties such as antibacterial, antiviral, antiparasitic, catalytic, anti-cancer, anti-allergic and radioprotecting. Lf is usually used as additives of food and cosmetics. The research of lactoferrin has been increasingly reported, and the application of lactoferrin as a drug carrier has drawn extensive attention over the recent year. In this paper, researches of lactoferrin as drug carriers are classified and summarized in brain targeting, liver tumor targeting, lung tumor targeting and oral delivery systems according to their different characteristics.

Objective To evaluate the clinical value of fasting blood glucose (FBG) in the diagnosis of multiple organ dysfunction syndrome (MODS) caused by pulmonary infection in elderly patients with diabetes. Methods Patients over 65 years old with diabetic pulmonary infection admitted to Department of Cadres Ward of Bethune International Peace Hospital of PLA from July 2015 to December 2016 were enrolled. According to the patient's highest FBG level during pulmonary infection, all patients were divided in two groups. The cases whose FBG ≥8.83 mmol/L were served as suspicious multiple organ dysfunction syndrome in the elderly (MODSE) group, and those had FBG < 8.83 mmol/L were served as suspicious non-MODSE group. The incidence of MODSE in suspicious MODSE group and suspicious non-MODSE group was compared. The receiver operating characteristic curve (ROC) was drawn, and the clinical value of highest FBG in the diagnosis of MODSE caused by pulmonary infection in elderly patients with diabetes was assessed. Results 119 elderly patients with diabetes and pulmonary infection were enrolled in the analysis. All patients were male, with age of 76-105 years with an average of (89.41±4.16) years. Among 119 patients, 55 of them with suspected MODSE, 64 of them with suspected non-MODSE. The incidence of MODSE in suspicious MODSE group was significantly higher than that in suspicious non-MODSE group (78.2% vs. 12.5%), with statistically significant difference (χ2 = 52.108, P = 0.000). The area under the ROC curve of the highest FBG for diagnosis of MODSE was 0.895, and 95% confidence interval (95%CI) was 0.839-0.951 (P < 0.001). When using FBG ≥ 8.83 mmol/L to diagnose MODSE induced by pulmonary infection in elderly patients with diabetes, the sensitivity was 84.3% and the specificity was 82.4%. Conclusion FBG ≥ 8.83 mmol/L, as an indicator reflecting the changes of metabolic function, have a diagnostic value for MODSE caused by pulmonary infection in elderly patients with diabetes.

[Objective] Expressions of human epidermal growth factor receptor 2(HER-2),p53,estrogen receptor (ER),and progesterone receptor (PR) in tissues of breast invasive ductal carcinoma are not only applied to determine the therapeutic regimen,but they may also be related to the prognosis.We investigated the levels of these proteins among different clinical stages and the correlations.[Method] One hundred and thirty-eight tissues from cases with breast invasive ductal carcinoma were tested with immunohistochemistry.New scoring standards and rank test were applied.The indices were digitalized and semi-quantified.[Results] In the tissues from high clinical stage,the expression of HER2 was significantly increased,while expression of PR was markedly decreased.[Conclusion] Expression of HER2 and PR might be better markers for predicting clinical stages and prognosis.

Purpose:The efficacy of evaluation of changes of tumoral uptake of 3'-deoxy-3'-[~(18)F] fluorothymidine (FLT) was comparatively analyzed with that of ~(18)F-FDG at early stage after anticancer chemotherapy.Materials and Methods:Cells derived from human lung adenocarcinoma were incubated with cisplatin (CDDP),5-fluorouracil(5-FU),doxorubicin (Dox),for 1,4,24 and 72h.The doses(CD-DP: 67 μM; 5-FU 1,540 μM;MTX: 440 μM;) were determined corresponding to a estimated 10% - 95% proliferation inhibition.The cells were allowed to recover before FLT or FDG being added into the culture media for 60 min.Cell counts,viability,estimated by MTT method,were used to evaluate the cytotoxic effects of chemotherapy.Results: FLT uptake was increased significantly at 1 and 4 h after treatment with 5-FU( 145 ± 12%,150 ± 14%,P <0.01).decreased at 24 h and 72 h.In contrast,FLT accumulation was significantly reduced at cytostatic concentrations of CDDP at different time.The uptake of FDG did not change significantly at early time points after treatment,but decreased at 72 h.Conclusion: The tumor cell uptake of FLT revealed specific changes depending on the auti-cancer drug used at much earlier time than FDG after chemotherpay.
