OBJECTIVETo observe the effect of Shenshuaining Granule (SG) combined telmisartan on serum creatinine (SCr) levels and urinary albumin contents in diabetic nephropathy (DN) patients, and to explore its efficacy.
METHODSTotally 204 DN patients were recruited, and further assigned to 3 groups, i.e., the early DN group, the clinical stage of DN with normal renal function group, the clinical stage of DN with insufficient renal function group. Patients in the same group were randomly allocated to the telmisartan treatment group, the SG treatment group, and the combination of SG and telmisartan treatment group, 68 in each group. Patients in the telmisartan treatment group took telmisartan tablet, 80 mg per day, once daily. Those in the SG treatment group took SG, 5 g each time, 3 times per day. Those in the combination of SG and telmisartan treatment group took telmisartan tablet (80 mg per day, once daily) and SG (5 g each time, 3 times per day). The therapeutic course for all was 3 successive months. SCr levels, serum urea nitrogen (BUN),24 h urine microalbumin (24 h U-MA) were detected before and after treatment. Results In three different treatment groups, 24 h U-MA decreased after treatment in the telmisartan treatment group; SCr and BUN decreased after treatment in the SG treatment group; and 24 h U-MA, SCr and BUN decreased after treatment in the combination of SG and telmisartan treatment group (P<0.05). In the clinical stage of DN with insufficient renal function group, SCr obviously increased after treatment in the telmisartan treatment group (P <0. 05). In the 3 DN stages, SCr and 24 h U-MA obviously decreased in the combination of SG and telmisartan treatment group, when compared with the telmisartan treatment group and the SG treatment group (P<0.05). Compared with the telmisartan treatment group, SCr and BUN obviously decreased in the SG treatment group, but 24 h U-MA quantitation obviously increased (P<0.05). BUN obviously decreased in the combination of SG and telmisartan treatment group (P<0. 05).
CONCLUSIONThe combination of SG and telmisartan could decrease urinary albumin, and stabilize SCr levels.

BACKGROUND: Few studies have reported the effects of early tracheotomy in acute severe asthmatic patients. We report two patients with acute severe asthma who were successfully treated with early tracheotomy. METHODS: The two patients with acute severe asthma were retrospectively reviewed. They had been treated at the Department of Emergency and Critical Care, Renji Hospital, Shanghai Jiaotong University School of Medicine. RESULTS: They developed progressively hypercapnia and severe acidosis, and were not improved after conventional therapies. Early tracheotomy after mechanical ventilation decreased airway resistance and work of breathing, and corrected hypercapnia and acidosis. Adequate gas exchange was maintained after tracheotomy. The two patients were subsequently weaned from mechanical ventilation and discharged. CONCLUSION: Early tracheotomy could be a valuable approach in certain patients with severe asthma.

OBJECTIVETo screen the mutations of the low density lipoprotein receptor (LDLR) gene in a familial hypercholesterolemia (FH) family, and analyze the LDL-uptaking function of LDLR on lymphocytes of patients.
METHODSGenomic DNA was extracted from four affected members in a Chinese FH family. The presence of apoB100 gene R3500Q mutation which results in familial defective apolipoprotein B100 (FDB) was excluded first. Fragments of the LDLR gene were amplified by touch-down polymerase chain reaction (Touch-down PCR) and analyzed by single-strand conformational polymorphism (SSCP). The suspect fragments of the LDLR gene were cloned and sequenced. Furthermore, the lymphocytes bounded with fluorescent-labeled LDL (DiI-LDL) were measured by fluorescence flow cytometry.
RESULTSA nonsense mutation was identified in exon 10 of LDLR gene. This mutation gave rise to a premature stop codon (W462X), resulting in the absence of most of the LDLR domains. It was detected in all the affected members of the FH family. The ratios of functional LDLR in lymphocytes from patients and normal controls were 63.7% and 77.3% respectively. As a result, the activity of the functional LDLR in patients was just 82.4% of that in the normal controls.
CONCLUSIONIt is possible that the W462X mutation of LDLR gene is the main cause for the disease in this family.

OBJECTIVETo provide new germplasm materials for breeding new varieties of Pseudostellaria heterophylla.
METHODThe method of single plant selection was adopted, with the comparative experiments being carried out under the same conditions in Shibing county. The 8 plants of Shibing SB-4 were compared respectively with factor analysis for 27 phenotypic traits and 8 yield traits, and single factor variance analysis for the contents of polysaccharides.
RESULTUsing factor analysis, 27 phenotypic traits were classified into 7 principal divisors and 8 yield traits were simplified into 3 principal divisors. The 4 strains of P. heterophylla, ZT-01, ZT-02, ZT-06 and ZT-07, performed better than others in the phenotypic traits, and ZT-01, ZT-02, ZT-03 and ZT-07 in the yield traits. The contents of polysaccharides of ZT-01, ZT-02, ZT-05 and ZT-08 showed significantly higher value.
CONCLUSIONThere is significant difference among the 8 strains of P. heterophylla in phenotypic traits, yield traits and quality traits, making it possible to select certain strains for different purposes. ZT-01 and ZT-02 can be breaded further. ZT-06 and ZT-07 were used as ornamental cultivars for its great phenotypic traits. ZT-03 with good resistance and high yield was taken as resistant variety, and ZT-05 would face next selection on the basis of its high content of polysaccharide.
