OBJECTIVETo compare the effects of puerarin and granulocyte colony-stimulating factor (G-CSF) in treating acute myocardial infarction (AMI) and on the size of infarcted area and cytokines.

METHODSSeventy-nine patients with anterior AMI were randomly divided into three groups, they were treated with conventional Western medical treatment, but to the puerarin group (PG) and the G-CSF group (GCG) puerarin and G-CSF was given additionally, respectively. The infarcted size, plasma G-CSF, matrix metalloproteinase-9 (MMP-9), serum interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) were detected before and after treatment.

RESULTSThe infarcted size was positively correlated to the levels of G-CSF, MMP-9, IL-6 and TNF-alpha before treatment ( r = 0.45, 0.42, 0.44 and 0.42, P<0.01 ). The infarcted size in the PG and the GCG decreased on the 28th day (P<0.01), the level of G-CSF, MMP-9, IL-6 and TNF-alpha in the PG on the 7th day all decreased (P<0.05), but these indexes in the GCG increased (P<0.05), while those in the control group were unchanged (P>0.05).

CONCLUSIONPuerarin and G-CSF are effective in decreasing infarcted size, but their effects on cytokines are different entirely.

The in situ gel systems can form gel in situ after administration to achieve sustained release, thus provides a promising strategy for drug delivery systems. The aim of this study was to design and prepare in situ gel systems for the oral delivery of ibuprofen (IBU-ISG) and study its pharmacokinetics in Beagle dogs. The characteristics of the basic material of gellan gum (Kelcogel, Kel) and sodium alginate (Manugel, M) were studied through investigating the complex viscosity of the Kel or M solution with or without different concentrations of calcium ion or sodium citrate to ascertain the amount range of the excipients. The measurement of complex viscosity of the solution (0. 5% Kel and 1% M) with different concentrations of sodium citrate and calcium ion was carried out to select the suitable proportion of calcium ion and sodium citrate. The formulation of binary IBU-ISG was optimized by monitoring the complex viscosity before gelling in vitro release property. The optimized formulation contains 1.0% sodium alginate, 0.5% gellan gum, 0. 21% sodium citrate and 0.056% calcium chloride. A single oral dose of IBU-ISG and reference formulation (IBU suspension) were given to each of the 6 healthy Beagle dogs, ibuprofen in plasma at different sampling times was determined by RP-HPLC. The pharmacokinetics parameters in 6 Beagle dogs were calculated. The Tmax of IBU-ISG and reference formulation were (1.8 +/- 0.6) and (0.4 +/- 0. 1) h. The Cmax values were (29.2 +/- 7.6) and (37.8 +/- 2.2) microg x mL(-1). The T(1/2) were (2.3 +/- 0.5) and (2.0 +/- 0.9) h, and the AUC(0-t) were (131.0 +/- 38.6) and (117.3 +/- 23.1) microg x mL(-1) x h, respectively. The binary IBU-ISG was successfully prepared.

Objective To explore the clinical application and effect of the transplantation of the cutaneous fibular flap combined with anterolateral thigh flap for the repair of complex tissue defect of the leg. Methods The cutaneous fibular flap combined with anterolateral thigh flap in series connection or parallel connection transfer were applied to repair complex tissue defect of the leg in 36 cases. 10 cases were fresh non-infectious wound 26 cases were delayed infectious wound. The area of wound ranged from 25 cm × 18 cm to 45 cm × 13 cm (36 cm × 16 cm on average). The area of anterolateral thigh flap ranged from 12 cm × 13 cm to 32 cm × 18 cm. The area of the cutaneous fibular flap ranged from 2.0 cm × 1.5 cm to 18.0 cm × 16.0 era. The length of fibular transplantation ranged from 10 cm to 24 cm. 30 cases were combined in parallel connection transfer, 6 cases were combined in series connection transfer, 5 cases were repaired in emergency, 5 cases were repaired in subemergency, 26 cases were repaired in delay. Results All cases were successfully repaired in 36 cases.35 cases were followed up. A mean follow-up was 29 months. Arterial crisis occurred in 1 case, venous crisis occurred in 2 cases 34 flaps survived completely and 2 cutaneous fibular flap survived partially in parallel connection which were later healed by skin transplantation.32 cases were healed in first stage, 4 cases were healed in second stage, (healing time ranged from 12 to 18 days), Bone healing time ranged from 3 to 6 months in fibula transplantation. The Enneking score system was applied to evaluate the leg function. Of the 35 cases, the mean scores was 26 (their scores ranged from 23 to 28).The functions of all supplied regions were not found malfunctional. Conclusion Transplantation of the cutaneous fibular flap combined with anterolateral thigh flap is an optimal method to repair the complex tissue defect of the leg.

Objective To explore the importance and methods of retaining articularis during pri- mary total hip arthroplasty(THA)and reconstruct soft tissue balance of hip joint after THA.Methods From February 2003 to August 2005,41 eases(43 hips)including 19 males and 22 females at age of 46- 80 years(mean 66.5 years)were treated with THA with retained capsule(Group R)and other 42 cases (44 hips)including 20 males and 22 females at age of 43-80 years(mean 64.3 years)with standard THA (Group S).Preoperative diagnosis found femoral neck fractures(GardenⅢⅣ)in 13 cases(13 hips)in Group R and 14(14 hips)in Group S;acetabular dysplasia(CroweⅢ)in 9(9 hips)in Group R and 8 (hips)in Group S;Osteoarthritis in 6(8 hips)in Group R and 7(8 hips)in Group S;and femoral head osteonecrosis(FicatⅢⅣ)in 13(13 hips)in Group R and 13(14 hips)in Group S.There were 13 hips of cement prostheses in Group R and 11 in Group S,8 cementless prostheses in Group R and 8 in Group S, 22 cement and cementless prostheses in Group R and 23 in Group S.Gibson's approach was used in both groups.Group R used the method of retaining capsule and little supination muscles during the operation to reconstruct responsibly soft tissue balancing of postoperation for THA.For comparison,Group S used the method of standard which resected a lots of capsule and didn't reconstruct it.The comparative items between Group R and Group S included incisional length,operative time,operative bleeding,drainage transfusion, infection,dislocation,postoperation standing,postoperation walking and Harris's score.Results All cases in Group R and Group S were followed for 6-22 months(mean 16.5 months in Group R and 16.7 months in Group S).There was significantly statistical difference upon interoperative and postoperative data between Group R and Group S.The result of Group R was significantly better than that of GS.Conclu- sion Retaining articularis during primary THA can minimize operative trauma,reconstruct soft tissue bal- ance and augment hip stability to get postoperative functional recovery.

OBJECTIVETo explore the association between chorioamnionitis and brain injury in preterm infants.

METHODSA total of 88 preterm infants (28-34 weeks), who were born between June 2008 and June 2011, were divided into a case group (n=41) and a control group (n=47) according to whether or not they had chorioamnionitis. All the infants were examined by brain ultrasonography periodically after birth and underwent brain diffusion weighted imaging (DWI) between 3 and 7 days after birth. The two groups were compared in terms of the incidence of periventricular leukomalacia (PVL) and periventricular and intraventricular hemorrhage (PVH-IVH) by brain magnetic resonance imaging (MRI) at the corrected gestational age of 40 weeks.

RESULTSThere was statistical significance in the incidence of PVL between the case and the control groups (32% vs 6%; P<0.05), but no significant difference in the incidence of PVH-IVH between the two groups (27% vs 23%; P>0.05).

CONCLUSIONSChorioamnionitis is associated with brain injury in preterm infants, increasing the incidence of PVL but having little influence over the incidence of PVH-IVH.

OBJECTIVETo study the prevention & treatment effect of cordyceps sinensi on bleomycin-induced pulmonary fibrosis (PF) in mice.

METHODRats were divided into 4 groups. In BM group (model), pulmonary interstitial fibrosis model was established through nasal dripping of 5 mg x kg(-1) bleomycin. In PCT group (prevention & treatment with cordyceps sinensi), cordyceps sinensi was orally administered 48 h before bleomycin dripping. In CT group (treatment with cordyceps sinensi), cordyceps sinensi was orally administered at 14 d after bleomycin dripping, and NC group (normal mice, control). At 28 d, bronchoalveolar lavage fluid (BALF) and lung tissue were collected, right lung received HE staining and masson staining, the change in cell micro-structure was observed under electron microscope, the hydroxyproline (HYP) content in lung tissue of left lung was detected through acidolysis method, and TGF-beta1, IFN-gamma and IL-4 concentration in BALF was detected through ELISA.

RESULTCompared with those in BM group, mouse lung coefficient decreased significantly (P < 0.05), alveolitis and fibrosis degree improved significantly in PCT and CT groups (P < 0.05), HYP content in lung decreased (P < 0.05). TGF-beta1 and 1L-4 content in BALF decreased significantly in each drug intervention group, IFN-gamma content increased significantly (P < 0.05).

CONCLUSIONThe cordyceps sinensi can alleviate bleomycin-induced alveolitis and fibrosis degree in a certain degree. The mechanism of the alleviation is possibly due to its inhibition of TGF-beta1 expression and its regulation of imbalance of the type I and II cytokine in lung tissue.

OBJECTIVETo assess whether intracytoplasmic morphologically selected sperm injection (IMSI) of testicular sperm improves the clinical outcome in patients with azoospermia.

METHODSWe performed conventional intracytoplasmic sperm injection (ICSI) for 66 patients diagnosed with azoospermia and IMSI for another 39 using testicular sperm selected at high magnification ( x 6000), and comparatively analyzed the clinical outcomes of the two techniques.

RESULTSThere were no statistically significant differences between conventional ICSI and IMSI in the rates of pregnancy (51.52% vs. 56.41%) and implantation (30.67% vs. 35.29%), although the rate of early abortion was lower in the IMSI than in the ICSI group (4.50% vs. 11.76%).

CONCLUSIONIMSI of testicular sperm may effect a lower rate of early abortion than conventional ICSI in patients with azoospermia.
