Objective To study the relationship between adiponectin and pulmonary function, age and gender in pa-tients with chronic obstructive pulmonary disease (COPD). Methods A total of 120 COPD patients with normal body mass index (BMI＜24 kg/m2 ) were selected and divided into acute exacerbation group (n=60) and stable group (n=60). And 60 healthy people were included as controls. There were equal numbers of male and female in each group. The serum level of ad-iponectin was sdetected by ELISA in there groups. The pulmonary function was collected,and values of FEV1/FVC, FEV1%predicted and RV/TLC were calculated in three groups. Results The serum level of adiponectin was significantly higher in acute exacerbation group than that of stable group and control group (P＜0.05). And the serum level of adiponectin was significantly higher in stable group than that of control group (P＜0.05). The serum levels of adiponectin were signifi-cantly higher in female patients than those of male patients (P＜0.05). The values of FEV1%, FEV1/FVC and FEV1%pre-dicted were significantly lower in acute exacerbation group and stable group than those of control group. The value of RV/TLC was significantly higher in acute exacerbation group and stable group than that of control group (P＜0.05). There was a negative correlation in serum levels of adiponectin, FEV1%predicted and FEV1/FVC between acute exacerbation group and stable group. But there was a negative correlation in serum levels of adiponectin and RV/TLC between these two groups ( P＜0.01). There was a positive correlation between serum level of adiponectin and age in male patients (r=0.943,P＜0.01). Con-clusion The serum level of adiponectin was significantly increased in patients with COPD, which suggested that adiponec-tin played an important part in proinflammatory and might be closely related with airway resistance. The serum level of adipo-nectin might exist gender differences and may be related with age.

Objective To study the distribution of drug resistance mutations and genotypes in the patients with chronic hepatitis B(CHB)in Taicang area.Methods 350 cases of CHB were selected and detect the drug resistance mutations and genotypes before using nucleoside(acid)anti-viral drugs.The correlation between the drug resistance mutations with genotypes in CHB patients was analyzed.Results Among 350 cases of CHB,the distribution of genotypes was genotype B in 172 cases,accounting for 49.14%, genotype C in 164 cases,accounting for 46.85%,genotype D in 9 cases,accounting for 2.57%,mixed genotype of B and C in 5 ca-ses,accounting for 1.42%,no other genotypes were found.In this study,the drug resistance mutations were detected in 58 cases,in-cluding 22 cases of genotype B,35 cases of genotype C and 1 case of genotype D,no drug resistance mutations were found in mixed genotype B and C.The drug resistance mutations sites:lamivudine resistance-associated mutations in 36 cases(10.28%),and adefo-vir resistance-associated mutations in 16 cases(4.57%)and entecavir associated resistance mutations in 6 cases(1.71%).Conclusion The genotype of CHB patients in Taicang area was dominated by genotype B and C,which accounting for more than 90% and the proportion of these two kinds of genotype is similar.The proportion of drug resistance mutation occurrence in the patients with gen-otype C is higher than that with genotype B.The lamivudine resistance-associated mutation has the highest proportion of drug re-sistance occurrence.It is suggested that the CHB patients with undefined medication history and recurrence treatment should be per-formed the drug resistance detection for selecting the targeted therapeutic schemes before accepting nucleoside(acid)drug therapy.

It is a promising method to use Liposomes as a carrier in the transdermal delivery system.Presently,llposomes,deformable liposomes,and ethosomes are in common use.The transdermal mechanism of the liposomes is to promote the velocity and the amount of the drugs of transdermal absorbance by affecting the keratoderma,acting on the skin appendages and changing the exterior characteristic of the drugs to make them permeate the skins.The Mechanism of the actions includes hydration.penetration,transforamation,and osmotic pressure driving effect,etc.The liposomes have been approved to have abroad prospect of application in the transdermal delivery system.

The DegP protein, functioning as both chaperone and protease, plays a critical role in degrading and removing denatured or damaged proteins in the cellular envelope during heat shock and other stresses. So far, several proteins have been identified as its natural targets. A carboxyle-terminal peptide derived from the PapG pilus, one of the in vivo substrates for DegP, has been shown to activate the protease. Nevertheless, neither the details nor the physiological implications of such activation have been studied. The evidence that DegP undergoes conformational changes upon binding the peptide derived from C-terminal sequence of pilus subunit PapG has been presented. It demonstrated that upon binding this peptide, detectable changes can be observed for both secondary and tertiary structures of DegP, as examined by CD spectroscopy. Gel filtration and dynamic light scattering analysis also revealed that the size of DegP becomes smaller to a minor extent. Moreover, both the hydrophobic surfaces and catalytic sites of DegP were found to expose slightly in the presence of the peptide. Upon peptide binding, a less flexible and more rigid conformation of DegP was obtained as analyzed by fluorescence anisotropy. The physiological implications of these observations for DegP are discussed.

In recent years, pharmacological researches of Chinese medicine have found that single Chinese exterior-relieving medicines such as Pueraria, Semen Sojae Praeparatum and Cimicifuga had very good anti-osteoporosis effect. They can significantly improve the bone mineral density (BMD) and bone mineral content(BMC), promote bone formation, and prevent bone absorption. Based on relative documents from home and abroad, this paper analyzed the current situation and provided new ideas and methods for prevention and treatment of osteoporosis.

Objective To investigate the etiology and prevention of venous thrombosis (VT) following laparoscopic cholecystectomy (LC). Methods A retrospective analysis on clinical records of 12 cases of VT following 258 cases of LC in this hospital from January 2002 to June 2004 was carried out. Results [WTBZ]The operation time was 17~58 min (mean, 38 min), and the intraoperative blood loss was 15~100 ml (mean, 45 ml). In 11 cases of superficial vein thrombosis, on a treatment for 6~8 days the symptoms of redness, swelling, heat, and pain vanished. Re-examinations of color Doppler ultrasonography revealed disappearance of thrombosis, and an anticoagulation therapy with Warfarin was given. Follow-ups for 6~12 months found no recurrence. In 1 case of deep femoral vein thrombosis accompanying pulmonary embolism, an anticoagulation therapy was employed for 4 months and a follow-up for 6 months showed no recurrence. Conclusions The development of VT following LC is correlated to patients' high-risk factors, carbon dioxide pneumoperitoneum, and anesthesia administration. Emphasis should be on active countermeasures during peri-operative period.
