Objective To compare the clinical efficacy of multi-target lateral puncture combined with intracranial pressure monitoring in treatment of basal ganglia hypertensive cerebral hemorrhage. Methods Sixty-six patients of basal ganglia hypertensive cerebral hemorrhage, with bleeding volume over 40 ml were divided into experimental group (36 cases) and control group (30 cases) by random digits table method. Patients in experimental group underwent multi-target puncture combined with routine intracerebroventricular treatment of intracranial pressure monitoring,and patients in control group underwent frontotemporal craniotomy and small hematoma decompressive craniotomy. The operation time, length of stay, hematoma evacuation rate, catheter drainage time, total amount of mannitol, Glasgow Coma Scale (GCS) scores 3 days after treatment, complication rate and 3-month Glasgow Outcome Scale (GOS) scores were recorded and compared between two groups. Results The operation time, length of stay, hematoma evacuation rate 1 day after treatment, and total amount of mannitol in experimental group were significantly lower than those in control group: (67.5±8.0) min vs. (109.3±9.6) min, (18.6±4.2) min vs. (23.3±5.9) min, (59.7±9.2)% vs. (80.4±11.6)%, (668.6±83.5) g vs. (1 430.4±107.1) g, P<0.01. The hematoma evacuation rate 3 days after treatment, catheter drainage time and GCS scores 3 days after treatment between two groups had no significant differences (P>0.05). The GOS scores in experimental group: 5 points (9 cases), 4 points (10 cases), 3 points (8 cases), 2 points(5 cases), and 1 point(4 cases). The GOS scores in control group: 5 points (4 cases), 4 points (4 cases), 3 points (7 cases), 2 points (9 cases), and 1 point (6 cases). Long curative effect in experimental group was better than that in control group (Z =2.318, P =0.020). The incidence of intracranial air in experimental group was significantly higher than that in control group: 27.8%(10/36) vs. 3.3%(1/30), P<0.05. Other complications had no significant differences between two groups (P>0.05). Conclusions Multi-target lateral puncture combined with intracranial pressure monitoring in treatment of basal ganglia hypertensive cerebral hemorrhage has more advantages, including less trauma, wide surgical indications, short operation time and hospital stay, less postoperative mannitol, and decreased mortality rate. For older, patients with organ dysfunction, and patients who can not tolerate craniotomy, it is an effective treatment, and worthy of promotion.

Melamine is a kind of triazine compound and the fluorescence of it can get enhanced in the presence of cationic surfactant in weak alkaline medium. A new fluorescent spectrophotometry based on this principle) has been developed to determine melamine under the optimum conditions such as Tris-HCl buffer solution), pH 8.0 and with CTMAB as sensitizing agent. The linear range, detection limit and relative standard deviation were 25-1000 μg/L, 19 μg/L and 1.6%,respectively. The samples were pretreated according to the solid phase extraction monolithic column to carry out the detection of real milk. This method is simple, rapid and accurate. It can be used to screen and detect the milk samples primarily.

Objective To investigate the relationship between microalbuminuria to estimated glomerular filtration rate (mALB/GFR) ratio and incidence of contrast induced nephropathy (CIN) after underwent percutaneous coronary intervention (PCI). Between March 2010 to August 2011, a total of 137 patients who underwent PCI were selected. Anthropometric measures, lipid profiles, fasting blood glucose, CRP, base creatinine and microalbuminuria were measured before operation. Glomerular filtration rate was calculated by MDRD formula. Contrast volume (CV) was recorded after the operation for each patient. Serum creatinine was measured 24 h, 48 h, 72 h after operation, respectively. CIN was defined as an increase in serum creatinine levels of 25% or 44 μmol/L or more from baseline within 72 h after PCI. All patients were divided into group A (CIN group) and group B (No CIN group). Results Eighteen (13.1%) patients developed CIN(group A). The others were group B (no CIN group). The level of CRP, base creatinine, microalbuminuria and mALB/GFR in group A were significantly higher than that in group B ( P < 0 . 01 ) . GFR in group A was lower than that in group B (P < 0.05). Logistic regression analysis indicated that the level of base creatinine , microalbuminuria GFR and mALB/GFR were independent risk factors of CIN occurrence (P < 0.05). The receiver-operator characteristic curve analysis indicated that a mALB/ GFR ratio of 1.17 was a fair discriminator for CIN,and sensitivity were 94.1%, specifity were 72.5%. Conclusion A mALB/ GFR ratio was a independent predictor of CIN after PCI.

OBJECTIVETo discuss the clinical effects and superiority of applying external fixation and bone transport to treat osteomyelitis and bone defect of femoral bone.

METHODSFrom August 2008 to December 2013,16 patients with osteomyelitis and bone defect of femoral bone were treated including 11 males and 5 females with an average age of 42 years old ranging from 13 to 62 years old. The average course of disease was 18 months ranging from 2 months to 4.5 years, and the average length of bone defect was 7.8 cm ranging from 4.5 to 15 cm. The bone defect of all cases were treated by external fixation and bone transport, the bone transport began at 1 week after operation, 1 mm per day and 4 times per day.

RESULTSAll patients were followed up for 10 to 36 months (means 22.5 months). One patient did not cooperate with treatment leads to the failure, then took the amputation. The remaining 15 cases of osteomyelitis were under control, including 12 cases of bone transport achieved one stage bone union, 3 cases achieved bone union via bone graft from iliac bone. The bone union time was 5 to 13 months(means 7.9 months). Thirteen patients almost obtained the same length of two lower extremities,2 patients had shortening of 1.5 to 2 cm. The time of moving the external fixation was from 6 to 16 months (means 9.3 months).

CONCLUSIONApplication of external fixation and bone transport is an effective method in treating the osteomyelitis and bone defect that can control the infection, eradicate wounds, and be the equalization of limb length.

BACKGROUND: At present, the commercial artificial small vascular grafts (diameter < 6 mm) are still unsatisfactory, due to poor blocompatibility and low long-term patency rate. Therefore, finding a vascular substitute with normal biological function and studying construction and function of tissue-engineered blood vessel have become hot topics recently.OBJECTIVE: To construct a novel tissue-engineered blood vessel by rabbit bone marrow mesenchymal stem cells (MSCs) and vascular acellular matrix, and to investigate the biocompatibility and patency rate of tissue-engineered blood vessels.DESIGN, TIME AND SETTING: An in vitro randomized controlled study at level of cytology and histopathology was performed at the Laboratory of Affiliated Drum Tower Hospital of Nanjing University Medical School from January 2006 to June 2008.MATERIALS: The decellularized vascular acellular matrix was obtained by a detergent-enzymatic procedure. MSCs from rabbits were isolated using density gradient centrifugation method and cultured in culture flasks coated with fibronectin. Subsequently, the expanded MSCs were seeded on the decellularized scaffolds, and then co-cultured in the self-made bioreactor to construct the tissue-engineered blood vessels.METHODS: Sixty rabbits were randomly divided into three groups. A1.0-cm abdominal aorta was sheared, and a tissue-engineered blood vessel was transplanted on the abdominal aorta using 8/0 polypropylene thread. Tissue-engineered blood vessel group: Tissue-engineered blood vessel was considered as the transplanted vessel; vascular acellular matrix group:Xenoma artery treated by vascular acellular matrix was considered as the transplanted vessel; xenoma artery group: Fresh xenoma artery was considered as the transplanted vessel.MAIN OUTCOME MEASURES: Immunocytochemical staining was used to identify the cultured MSCs. After 3 months of transplantation, the grafts were retrieved for digital subtraction angiography, pathological test and scanning electron microscope examination.RESULTS: Rabbits MSCs presented a whirlpool-like appearance at 8 days after culture. The immunocytochemistry results were consistent with the phenotype of MSCs. After high proliferation, MSCs were seeded onto the vascular acellular matrix for 12 days,and seed cells attached to well in the lumen of blood vessels. Three months after implantation, the patency rate was 90% of tissue-engineered blood vessel group and 80% of vascular acellular matrix group, which was superior to xenoma artery group (25%). At three months after transplantation, HE staining and scanning electron microscope demonstrated that internal, middle,and external membrane were clearly observed in the tissue-engineered blood vessel group, and the membrane morphology was similar to normal artery. The endothelial cells were covered completely. However, the endothelial cells were not covered completely in the vascular acellular matrix group, while mural thrombosis, mild proliferation of intima, and inflammatory cell infiltration were observed. The intima was thick and necrotic in the xenoma artery group, while lumens were stenotic and accompanied with a certain degree of thrombus organization.CONCLUSION: This study provides a new strategy to develop a tissue-engineered blood vessel with excellent biocompatibility and high patency rate constructed by rabbit MSCs and vascular acellular matrix.

ObjectiveTo explore the causes for descending of the serum testosterone (T) in middle-aged and elderly men with metabolic syndrome (MS).MethodsFifty-six male patients aged between 45 and 83 years old were investigated.Blood pressure,height and weight were measured,and body mass index (BMI) was calculated.Biochemical indice in fasting state [ fasting blood sugar (FBG),total cholesterol (TC),triglycerides (TG),low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol (HDL-C) ],fasting insulin (FIN),and the level of serum testosterone) were detected.An insulin resistance index (IR) was calculated using homeostasis model assessment (HOMA).Participants were divided into the MS group and the non-MS group according to CDS diagnostic standard.The relationships between the level of serum Testosterone and each index were analyzed.ResultsThe level of serum Testosterone was significantly lower in the MS group than that in the non-MS group [ (9.97 ± 3.87 ) nmol/L vs.( 13.73 ± 3.93 ) nmol/L,t =3.337,P ＜ 0.01 ].Multiple regression analysis showed that the level of serum testooterone was negatively correlated with age,waist circumference and HOMA-IR ( regression coefficients:- 0.214,- 0.329,- 0.317; standardized regression coefficients:- 0.730,- 0.597,- 0.313 ; t =- 5.833,- 4.681,- 2.686 respctively; P ＜ 0.01 ).ConclusionThe level of serum testosterone descends in middle-aged and elderly men with MS.The level of serum testosterone is closely related to age,waist circumference and insulin resistance

Objective To investigate the relationship between refractory hypertension and renal hemodynamics in end stage renal diseases (ESRD) patients.Methods ESRD patients were classified into:patients with refractory hypertension (group A) and patients with normal blood pressure(group B).Renal hemodynamic indices were ex- amined by duplex ultrasonography.Fasting serum lipid (TC,TG,HDL-C,LDL-C,Lp(a),ox-LDL) and serum parathyroid hormane (PTH) were determined in all patients.Results Significant differences were found in renal hemodynamic indices such as peak systolic velocity (PSV),mean flow velocity (MV),pulsatility index (PI),renal- aortic ratio (RAR) and in clinical index such as Lp(a) and ox-LDL between the two group.Refractory hyperten- sion patients had lower renal hemodynamic indices and higher Lp(a) and ox-LDL levels than in patients with con- trolled BP.Logistic regression analysis revealed that refractory hypertension was related with PSV,EDV,Pl and RAR,but not relevant with sex,age,dialysis time,hematocrit,BUN,creatinine,TC,TG,HDL-C,LDL-C, PTH,MV and RI.Conclusion Atherosclerotic renal artery stenosis and severe disorder in renal hemodynamics is likely the cause for refractory hypertention in ESRD patients.The rise of serum Lp(a) and ox-LDL might acceler- ate renal artery atherosclerosis.

AIM To study the pharmacodynamics of Baijin Granules [Mallotus apelta (lour.) Muell.Arg.,Smilax china L.],Zhuang medicine,on model rats with sequelae of pelvic inflammatory disease.METHODS The rat model for sequelae of pelvic inflammatory disease was built with mixed bacteria (Escherichia coli and Staphylococcus aureus) and mechanical injury.Subsequently,the rats were randomly divided into eight groups,including model,Baijin Granules low-,middle-,high-dose,positive control (dexamethasone and Huahong Granules),blank control and sham operation groups,with ten rats in each group.After 14 days of successive administration,the hemorheology and blood routine in rats' abdominal aorta were measured by collecting blood in 24 hours of last administration.The pathological morphology of uterine tissue was observed.RESULTS The hemorheology indexes,WBC count and neutrophil percentage were significantly decreased in the model rats,and the pathological morphology of uterine tissue was markedly improved.CONCLUSION Baijin Granules have good therapeutic effects on sequelae of pelvic inflammatory disease in rats.

The aim of the present study was to evaluate the effect of storage conditions,pretreatment,temperature,time and excystation solutions on in vitro excystation of Cryptosporidium oocyst.Cryptosporidium andersoni oocyst was used as a model and the results showed that 0.5% sodium hypochlorite could enhance the excystation rates.But there was no significant difference compared with oocysts untreated by sodium hypochlorite(P＞0.05).0.75% synthetic sodium taurocholate and 1% bile solution could urge the excystation of oocysts,which were significantly different compared with the excystation rate of oocysts in 0.25% trypsin solution or in PBS(P<0.05).The excystation rates of oocysts in acidic water (pH =3) were similar with the rates in PBS (pH =7.2) but significantly different from the rates in alkaline water (pH =9) (P<0.01).Additionally,the excystation rate of oocysts in water of 24℃ was significantly lower than in water of 37℃(P<0.01),and the excystation rate of oocysts raised gradually at 37℃ with the passage of time.It's concluded that temperature,acidity and excystation solution were vital factors for the in vitro excystation of Cryptosporidium oocyst.A higher excystation rate could be observed when oocysts were pretreated with 0.5% sodium hypochlorite and treated with 0.75% synthetic sodium taurocholate at 37℃ for 3 hours.
