Objective To observe the curative effect of low molecular heparin for treating secondary high coagulation state in the patients with nephrotic syndrome(NS) .Methods Total 87 cases of NS in our hospital were divided into the conventional treat‐ment group (n=42) and the low molecular heparin treatment group (n=45) .The routine treatment group was given the prednisone treatment and the low molecular heparin treatment group was treated by low molecular heparin combined with prednisone .The re‐lated indicators of blood coagulation before and after treatment were detected and the clinical curative effects in two groups were an‐alyzed .Results The coagulation related indicators in the conventional treatment group had no statistically significant difference be‐tween before and after treatment (P>0 .05) ,the prothrombin time(PT) and activated partial thrombin time(APTT) after treat‐ment in the low molecular heparin treatment group were significantly extended compared with before treatment ,while the concen‐trations of D‐dimer and fibrinogen were significantly decreased and the concentration of antithrombin Ⅲ was markedly increased compared with before treatment ,showing statistically significant differences between the two groups (P<0 .05);the patients of the low molecular heparin group patients had no bleeding after treatment .Conclusion Low molecular heparin combined with predni‐sone can reduce the secondary high condensation state in NS without bleeding and has a significantly clinical effect .

Objective To evaluate the efficacy of fascia iliaca compartment block with dexmedetomidine combined with ropivacaine for analgesia in the patients suffering from proximal femoral fractures.Methods Eighty emergency patients with proximal femoral fractures,aged 25-70yr,weighing 55-82 kg,of ASA physical status Ⅰ-[Ⅲ,were equally and randomly divided into 2 groups using a random number table:ropivacaine group (group R) and dexmedetomidine mixed with ropivacaine group (group DR).All the patients underwent fascia iliaca compartment block described by Dalens.0.4％ ropivacaine 30 ml was injected in group R,and 1 μg/kg dexmedetomidine 30 ml containing 0.4 ％ ropivacaine was injected in group DR.The severity of pain was assessed by VAS scores,and the level of sedation was assessed by Ramsay scores.At 30,60,90 and 120 min after injection (T1-4),VAS scores at rest and during activity were recorded,the effective analgesia (VAS scores at rest and during activity≤6) and satisfactory sedation (Ramsay scores 2-4) in group DR were also recorded,and the development of hemorrhage or hematoma at the puncture site,local anesthetic poisoning,adverse cardiovascular events and over-sedation was also recorded.Results Compared with group R,the rate of effective analgesia during activity was significantly increased at T2-4,and no significant change was found in the rate of effective analgesia at rest in group DR.In group DR,the rate of satisfactory sedation was 73 ％,88％,95％ and 95％ at T1-4,respectively,and no over-sedation occurred.No patients developed hemorrhage or hematoma at the puncture site,or local anesthetic poisoning in the two groups.Conclusion Fascia iliaca compartment block with 1 μg/kg dexmedetomidine combined with 4％ ropivacaine 30 ml can alleviate the early pain caused by passive activity without inducing obvious adverse reactions in the patients suffering from proximal femoral fractures.

Objective To perform a risk factor analysis of central retinal vein occlusion (CRVO) and branch retinal vein occlusion (BRVO),and compare the difference in risk factors between CRVO and BRVO.Methods Retrospective observational casecontrol study included 46 CRVO patients,33 BRVO patients and 79 control subjects with senile cataract or refractive error,the risk factors and blood lipid spectrum analysis were performed and compared.Results Multivariate linear regression analysis showed that higher serum levels of homocysteine (P ＜ 0.000 1),total cholesterol (P =0.003 0),lipoprotein (a) (P =0.027 0),hypertension (P =0.022 0) and shorter axial length (P ＜0.000 1) were significantly correlated with CRVO.BRVO was associated with higher serum levels of homocysteine (P ＜0.000 1),total cholesterol (P =0.008 0),hypertension (P =0.002 0),body mass index (P =0.004 0) and shorter axial length (P =0.001 0).There was no significant difference in risk factors between CRVO and BRVO patients on multivariate analysis.Conclusion Multiple systemic (hyperlipidemia,hypertension and hyperhomocystinemia) and ocular (shorter axial length) risk factors are associated with both CRVO and BRVO,but these risk factors are not different between CRVO and BRVO.

Spleen kidney Yang deficiency (SKYD) diarrhea is a common syndrome in tranditional Chinese medicine (TCM). Until now, there is not an ideal SKYD diarrhea rat model for the research. In this study, we compared single factor way (method I, injecting hydrocortisone and gavaging Sennae Folium) with compound factors way(method II, gavaging adenine, improper diet, exhaustion, and gavaging Sennae Folium) on establishing SKYD diarrhea rat model. After modelling, diarrhea index, D-xylose excretory rate, NOS/cGMP signal transduction system, organ index and histopathology examination were used to evaluate the two ways. The results showed that, compared with health group, all the assessment criterias of method I and method II had significant differences (P < 0.01, 0.05). In addition, the index such as diarrhea index, NOS/cGMP signal transduction system, organ index (kidney, testis and thymus) and histopathology examination had significant differences (P < 0.01, 0.05) between method I and method II. In conclusion, the compound factors modelling method better conforms to the symptom of diarrhoea model caused by SKYD. This new modelling method provides a basis for studying on TCM astringents warming and tonifying the spleen and kidney, relieving diarrhea.

OBJECTIVETo evaluate the safety of human umbilical cord derived-mesenchymal stem cell (UC-MSC) transplantation therapy in patients with decompensated liver cirrhosis.

METHODSUC-MSCs were transplanted intravenously into patients with decompensated liver cirrhosis. Serum levels of glucose (GLU), total cholesterol (TC), blood urea nitrogen (BUN), alpha fetoprotein (AFP), white blood cells (WBC), and prothrombin activity (PA) were detected at different time points after UC-MSCs transplantation.

RESULTSMost UC-MSC transplanted patients experienced an improvement in quality of life, to varying degrees. With the exception of low-grade fever in a few patients, side effects and oncogenic events were rare (treatment group: 1/38 vs. control group: 1/16; P more than 0.05). The UC-MSCs transplantation showed no effect on GLU, TC, BUN, AFP, WBC, or PA.

CONCLUSIONUC-MSCs transplantation in patients with decompensated liver cirrhosis is safe and may improve the patient's quality of life.

OBJECTIVETo explore the morbidity, burdens caused and risk factors of injuries among children and to provide information for policy making on prevention.

METHODSBy PPS sampling method, we selected 28 000 households in Beijing and using a questionnaire developed by UNICEF, TASC and China CDC.

RESULTSThe morbidity of child injury in Beijing was 2.25%, higher than that of adults (1.56%) with 6-9 year group the highest (2.83% ). The morbidity of boys was 3.04% higher than that of girls (1.37%). Among the 7 death cases, 3 were caused by injury(2 RTA, 1 drowning). The three leading causes of injuries were fall, animal bite and road traffic accident in children. Among children aged 0-5 years, fall, animal and burn/machine injuries were the leading causes. Among children aged 0-5 years, the leading causes were hurt by animals, fall and RTA with the leading causes as fall, sprain and RTA. The average medical cost of injury cases was 1617.57 Yuan. There were 3500 children (injured orphan) whose parents were injured leading to death or disability in Beijing in 2003.

CONCLUSIONInjury was the leading cause of child deaths in Beijing with children of 6-9 years old having the highest morbidity with RTA the most severe type of injuries in Beijing which affects both children and their parents.

OBJECTIVETo investigate the effects of different proportions of cryoprotectant to seminal plasma on the motility of post-thaw human sperm.

METHODSDifferent proportions of cryoprotectant to seminal plasma (1:1 and 1:3) were used for freezing sperm, and the forward movement and total motility rates of the frozen-thawed sperm were compared.

RESULTSThe forward movement and total motility rates were (58.60 +/- 5.57)% and (66.17 +/- 5.24)% before cryopreservation. The 1:1 proportion achieved post-thaw forward movement and total motility rates of (40.53 +/- 8.97)% and (51.23 +/- 9. 30)%, while the 1:3 (44.7 +/- 8.67)% and (51.50 +/- 7.40)%, respectively. Significantly decreased sperm motility was observed after cryopreservation (P < 0.05). Statistically significant differences were found in the forward movement but not in the total motility of the frozen-thawed sperm between the two proportions.

CONCLUSIONCryopreservation causes obvious damage to human sperm. Higher proportion of cryoprotectant to seminal plasma (1:3) can improve the forward movement of post-thaw sperm as compared with the lower one (1:1).

OBJECTIVETo investigate the effect of organic gallium and gallium chloride on bone metabolism and their therapeutic effect against tretinoin-induced osteoporosis in rats.

METHODSRat models of osteoporosis was established with intragastric administration of tretinoin at the daily dose of 85 mg/kg for 15 days and randomized into control, organic gallium and gallium chloride groups. After administration of the corresponding treatments (none for the control group) for 4 weeks, the changes of the indices for osteoporosis were evaluated through biochemical and pathological approaches.

RESULTSTretinoin induced obvious changes in bone structure and contents of bone calcium and other elements, causing also significantly increased tartrate-resistant acid phosphatase (TRAP) and alkaline phosphatase (AKP), which suggested the development of osteoporosis. Administration of organic gallium and gallium chloride treatments increased the bone density, bone cortex thickness and the percentage of bone trabecula, and Ga, Ca, P contents in the femur and teeth, but lowered the activity of TRAP and AKP, suggesting decreased bone conversion rate. Compared with gallium chloride, organic gallium required smaller dose with better safety to produce better therapeutic effect.

CONCLUSIONOrganic gallium can be safe and effective for treatment of tretinoin-induced osteoporosis in rats.

OBJECTIVETo establish malignant progression associated gene expression profiles in human brain glioma.

METHODSThe primary (WHO grade II), recurrent (WHO grade III) and re-recurrent (WHO grade IV) glioma specimens were sequentially collected from one single patient. Gene expression of different tumor specimens and normal brain tissue of the same patient was compared by microarrary techniques.

RESULTS197 differentially expressed genes with differential ratio > or = 3 were observed when compared with normal brain tissue. When the specimens (3 tumor, 1 normal brain) were paired with each other, 7 groups containing 489 genes (upregulated 193, downregulated 296) were observed. According to the descending frequency of the 109 genes with known function, they were the genes associated with development, metabolism, differentiation, signal transduction, DNA binding transcription, cellular receptor, immunity, ion-channel transportation, protein translation, cell backbone motion, stress, protooncogene and anti-oncogene and cell apoptosis, respectively.

CONCLUSIONFrom the 197 differentially expressed genes found in one glioma patient experiencing tumor malignant progression, 17 genes screened out by bioinformatics assay, may offer valuable information on molecular mechanisms on genesis and malignant progression of glioma.
