OBJECTIVETo explore the therapeutic effect of Pushen capsule (PSC) in treating primary hyperlipidemia.

METHODSTwo hundred and forty patients with primary hyperlipidemia were randomly divided into two groups, the 120 patients in the treated group treated with PSC (4 capsules, tid) and the 120 patients in the control group treated with Zhibituo tablet (3 tablets, tid), and they were administered at the same time with Zhibituo placebo. The therapeutic course for both groups was 4 weeks. The therapeutic effect and the effects on blood lipids and viscosity were observed.

RESULTSThe effective rate in the treated group was 76.3%, which was significantly higher than that in the control group (48.7%, P < 0.01). PSC showed a significant lowering effect on TC, TG and LDL-C and raising effect on HDL-C, and the effect in lowering TG was significantly better than that of Zhibituo (P < 0.01). PSC also showed a certain effect in decreasing whole blood viscosity of both high-sheared and low-sheared viscosity.

CONCLUSIONPushen capsule has promising blood lipid regulating effect in patients with hyperlipidemia, and some effects in lowering the blood viscosity.

OBJECTIVETo analyze the intermediate-term results associated with the use of Zweymtiller hip system.

METHODSReview the 116 cases (142 hips) who were treated with total hip replacement from 1996 to 2002 by a single surgeon using cementless Zweymüller hip systems.

RESULTSSixty-one cases (77 hips) were followed up, 50 cases (64 hips) were evaluated both clinically and radiographically while 5 cases (6 hips) and 6 cases (7 hips) were only evaluated clinically and radiographically respectively. The average follow-up period was 7.3 years (range 5 to 11 years). The mean preoperative Harris Hip Score was 46 while the mean postoperative Harris Hip Score was 93. Distal cortical hypertrophy and medullary sclerosis were observed in 30 hips (42.3%) and 33 hips (46.5%) respectively. Heterotopic ossification arose in 45 hips (63.4%). Radiolucent lines occurred in 27 stems (38.0%) but in no cups. Radiolucent lines were mostly observed in Gruen zones 1. Osteolysis occurred in 7 cups (9.9%) and 18 stems (25.4%). Osteolysis was mostly observed in Delee Zone 3 and Gruen zone 7. In the distal Gruen zones 3, 4 and 5, no radiolucent line or osteolysis was observed. No hips had been revised, 3 cups needed revision surgery because of aseptic loosening.

CONCLUSIONThe 5-11 years follow-up results are satisfactory, but osteolysis is common.

To investigate the effect of Protein kinase B on the expression and location of p21 in mouse early development. Immunopreciptation technology was used to detect the localization of p21 and Western blotting was used to analyze the expression of p21 after microinjecting mRNA of WT-PKB, myt-PKB and PKB-KD to mouse eggs. There was no obvious difference between the three kinds of mRNA in the expression of p21. But the cell localization altered. The p21 retain in cytoplasm after microjecting myt-PKB. In mouse fertilized egg PKB/Akt controls the cell cycle by changing the cell localization of p21.

OBJECTIVETo characterize a supernumerary marker chromosome (SMC) by comparative genomic hybridization (CGH), fluorescence in situ hybridization (FISH) and traditional cytogenetic techniques, and to explore the clinical application of these techniques in delineating de novo marker chromosomes.

METHODSA mental retardation patient received chromosome test by ordinary G banding. CGH and FISH techniques were used to analyze the origin of the de novo SMC, and N banding technique and C banding techniques were used to analyze the SMC structure. The phenotypic effects of the SMC were analyzed after the karyotype was determined.

RESULTSBy G banding technique, the patient was showed to have a mosaic karyotype with SMC: mos.47, XX, +mar [31]/48, XX, +2mar[29]. CGH analysis showed a gain of 15q11 --> q14, and the result was confirmed by FISH with chromosome 15 painting probe. The further FISH analysis showed the SMC had two signals with UBE3A probe for detecting Prader-willi syndrome/Angelman syndrome (PWS/AS). N banding and C banding analysis showed the SMC had a double satellite and double centromere, respectively. Combined with the above results, the karyotype of the patient was: mos.47, XX, +der (15) (pter --> q14::q14 --> pter) [31]/48, XX, +2der (15) (pter --> q14::q14 --> pter) [29]. ish der(15)(WCP15+, UBE3A++, PML-).

CONCLUSIONCGH is a valuable method to detect imbalanced chromosomal rearrangement. Combined with FISH and the traditional cytogenetic technique, it provides a valuable technique platform for characterizing the structure of the de novo SMC, and a basis for exploring the relation between karyotype and phenotype, prognosis and recurrent risk.

OBJECTIVETo study the efficacy, safety and reliability of colonic sac duct for first-stage repair of colorectal anastomotic leakage.

METHODSAn animal model of colon anastomotic leakage was established in 30 Tibet miniature pigs, which were randomly divided into treatment group and control group (n=15). Colon anastomotic leakage in the treatment group was repaired using the colonic sac duct, while the control group received conventional surgical repair. At 7, 14, and 21 days after the surgery, the healing of the anastomotic leakage was evaluated by examining the bursting pressure, tissue microvessel density and hydroxyproline content at the anastomosis.

RESULTSUsing the colonic sac duct, the anastomotic leakage was successfully repaired without death of the pigs or the occurrence of intestinal stenosis or necrosis. At 7 and 14 days after the surgery, the bursting pressure, hydroxyproline contents, and microvessel density in the treatment groups were higher than those in the control group, but such difference was not found at 21 days.

CONCLUSIONColonic sac duct allows effective repair of colon anastomotic leakage, and is especially useful for leakage lasting for 48-72 h complicated by severe abdominal infection.
