Objective To clarify the relationship of p63 and CD44 expressions with age and ultraviolet irradiation in the process of skin aging.Methods Full-thickness skin samples were obtained from the normal skin at different sites,including 44 sun-exposed sites(face,neck,dorsal aspect of the forearm),46 sun-protected sites(abdomen,thigh),and 31 semi-exposed sites(back,flexor aspect of the forearm,upper arm,leg),of 121 volunteers(63 males and 58 females).Of all the volunteers,55 were 10 t0 30 vears of age (young),41 were 31 to 50 years of age(adult),and 25 were 51 to 79 years of age(old).Immunohistochemisty using antibodies to p63 and CD44 was applied to detect the expression of p63 and CD44 in these specimens.Imaging analysis software was utilized to calculate the percentage of p63-expressing cells in basal layer as well as the expression level of p63 and CD44.Results In stratum basale,the percentage of p63-expressing cells decreased with age(r=-0.218,P＜0.05),but showed no significant difference among sun-exposed skin,semi-exposed skin and sun-protected skin(P＞0.05).The correlation between the expression intensity of epidermal p63 and age was negative in sun-exposed sites(r=-0.389,P=0.010),positive in sun-protected sites(r=0.341,P＜0.05).but non-significant in semi-exposed sites(P＞0.05).With regard to the expression of epidermal p63,no significant difference was observed among sun-exposed sites,sun-protected sites and semi-exposed sites in volunteers aged from 10 to 30 years.while in those aged from 31 to 50 years and from 51 to 79 years.sun-protected sites was significantly higher than semi-exposed sites followed by sun-exposed sites(all P＜0.05).There was a weak correlation between the expression intensity of epidermal CD44 and age(r=-0.083,P＜0.05),but no significant difierence was noted among the three kinds of sites(P＞0.05).Conclusions In stratum basale,the percentage of p63.expressing cells and the expression intensity Of CD44 negatively correlate with age,but have no correlation with ultraviolet irradiation.In individuals aged from 31 to 50 years and from 51 t0 79 vears.the expression of epidermal p63 decreases with the accumulation of sun-exposure.

Objective To discuss the pathogeny,treatment and prophylactic measures of postcholecystectomy syndrome (PCS).Methods The clinical data of 150 patients with laparoscopic PCS in our department from October 2000 to March 2009 were analyzed.Results Etiological factors were found in 131 patients:one hundred and twelve cases were due to the reasons of biliary system,including bile duct residual stones after cystic resection,the injury bile duct stenosis,a long residual cystic canal,nipple benign stricture,bile duct tumor etc;Nineteen examples were due to other reasons,including gallbladder stone merger reflux gastritis,gastroduodenal ulcer,diverticulum beside duodenal nipple,and so on,which resulted in the symptoms un-release after cystic resection.Nineteen cases were not found organic lesion.In ones whose etiological factors were definite,117 cases were treated with different surgeries according to different etiological factors;another 33 cases were treated with conservative treatment.Total 145 cases were followed up,and 139 cases in them were cured or relieved at different degrees.Conclusion Careful preoperative examination,normalized operation avoiding damaging bile duct and leaving behind bile duct stones can effectively prevent laparoscopic PCS.

AIM: To prepare flexible nanoliposomes made from active ingredients,phillyrin and volatile oil,from forsythia suspense and study their transdermal delivery system.METHODS: Flexible nanolipsomes of phill-yrin(WN group) and phillyrin in combination with forsythia volatile oil(OWN group) were prepared by the meth-od of membrane-dispersion.Its appearance and particle sizes were measured.Transdermal experiments were carried out on the modified Franz diffusion pool through in vitro mouse skin.HPLC was applied to determining the phillyrin content to compare transdermal rate and cumulative permeation amount of various flexible nanoliposomes.RESULTS: The particle size of the WN group was(180.7 ? 13.69)nm,the Zata potential was-48.8 mV,the average encapsulation percentage was(82.53 ? 2.68)%;the particle size of the OWN group was(212.3 ? 15.31)nm,Zata potential was-51.2 mV,the average encapsulation percentage was(70.49 ? 1.06)%.The accu-mulated permeation amount of the OWN group in 8 hours was(291.92 ? 23.22) ?g/cm2,its transdermal permea-bility in 8 hours was 36.49 ?g/(cm2.h),which was 6.10 folds that of the WS group and 1.92 folds that of the WN group.This difference had statistical significance(P

Objective Using the effect of microneedle array to investigate the feature and rule of transdermal drug delivery of sinomenine hydrogel patch.Methods The microneedles with different length and sinomenine hydrogel patch were prepared;The isolated rat skin was pretreated by different needle-shapes of microneedle array and different timepoints with the same needle-shape,and then sticked the sinomenine patch.The permeation rates of sinomenine were studied using a Franz diffusion cell and compared with passive diffusion of the rat skin untreated.Sinomenine content was measured by HPLC.Results The permeation rates of sinomenine via the skin pretreated with 100 and 200 ?m microneedles were 40.7 and 52.4 times to those of the untreated.The permeation rates of sinomenine via the skin pretreated 7 min with 200 ?m microneedles is 142.0 times to those of the untreated.When skins were pretreated using 200 ?m microneedles with different force, the drug permeation rates were increased with the force increasing.When the force exceeded 5 N,the drug permeation rates were equilibrium.Conclusion When transdermal drug delivery by using microneedle array-hydrogel patch,the permeation rates increase significantly.The needle-shape,skin pretreating time,and force of the microneedles play the important roles in the transdermal drug delivery.

Objective: To investigate the mortality and probability of premature death due to cardio-cerebrovascular diseases, malignant tumors, diabetes and chronic respiratory diseases and their trends among residents at ages of 30 to 69 years in Xiacheng District, Hangzhou City from 2005 to 2020, so as to provide insights into the development of the chronic disease control strategy. Methods: The data regarding the mortality of cardio-cerebrovascular diseases, malignant tumors, diabetes and chronic respiratory diseases among residents at ages of 30 to 69 years in Xiacheng District, Hangzhou City from 2005 to 2020 were captured from the Zhejiang Provincial Chronic Diseases Surveillance Information Management System, and the crude mortality, standardized mortality by the sixth population census data in Zhejiang Province in 2010 and probability of premature death for these four chronic diseases were estimated. The trends in mortality and probability of premature death were analyzed in Hangzhou City from 2005 to 2020 using average annual percent change (AAPC). Results: A total of 6 436 deaths occurred due to cardio-cerebrovascular diseases, malignant tumors, diabetes and chronic respiratory diseases among residents at ages of 30 to 69 years in Xiacheng District, Hangzhou City from 2005 to 2020. The crude and standardized mortality rates were 183.33/105 and 152.88/105, which both appeared a tendency towards a decline from 2005 to 2020 (AAPC=-1.099% and -2.926%, both P<0.05), and the probability of premature death reduced from 10.40% in 2005 to 6.78% in 2020, which appeared a tendency towards a decline (AAPC=-2.827%, P<0.05). The probability of premature death due to malignant tumors, diabetes and cardio-cerebrovascular diseases all appeared a tendency towards a decline from 2005 to 2020 (AAPC=-2.681%, -6.571% and -2.286%, all P<0.05), while no significant changing trend was seen in the probability of premature death due to chronic respiratory diseases (AAPC=-4.263%, P>0.05). The probability of premature death for these four chronic diseases reduced from 13.55% in 2005 to 9.36% in 2020 among male residents (AAPC=-2.150%, P<0.05), and reduced from 7.18% in 2005 to 4.22% in 2020 among female residents (AAPC=-4.149%, P<0.05). Conclusions The mortality and probability of premature death due to chronic diseases appeared a tendency towards a decline in Xiacheng District, Hangzhou City from 2005 to 2020, and there was a significant decline in the probability of premature death for malignant tumors, cardio-cerebrovascular diseases and diabetes.
