Objective To explore the relation of stroke and metabolic syndrome (MS), and provide theoretical evidence for prevention of stroke and MS. Methods Five hundred stroke patients accompanied with MS were enrolled, and divided into different types according to the distribution of the components of metabolic syndrome and abnormal metabolic condition. The systolic blood pressure(SBP) ,diastolic blood pressure( DBP),fasting glycemia ( FPG ), triglycerides ( TG ), total cholesterol ( TC ), low density density lipoprotern-cholesterol (LDL-C), high density density lipoprotern-cholesterol (HDL-C)of each patient were detected and recorded. Results Among these stroke patients with MS, most patients were 60 - 69 years old ( 39.60% ), and there was no significant difference between two gender( P = 0. 545 ). Among each component of MS, hypertension was most related to MS;patients complicated with hypertension + hyperlipidemia + hyperglycemia were the most major proportion of stroke patients with MS(48. 00% ). Conclusion MS and its components are all risk factors for stroke,and the more complication the patients had,the more patients suffered from stroke with MS. Targeted interventions of different type of abnormal condition has important prevention effect on MS and stroke.

Objective To investigate the anatomical classification of left intrahepatic bile duct (LHD) and the pattern of bile duct reconstruction during pediatric split liver transplantation and their relationship with postoperative biliary complications. Methods Clinical data of 75 pediatric recipients undergoing split liver transplantation were analyzed retrospectively. Before splitting the donor liver, iopromide injection was used for retrograde cholangiography through the common bile duct. According to the patterns of intrahepatic bile ducts in the second, third and fourth segments, the anatomical classification of LHD of the donor liver was determined. The biliary reconstruction regimens for different classification types of LHD were summarized. The incidence and treatment of biliary complications after pediatric split liver transplantation were analyzed. Results Among 75 donor livers, the anatomical classification of LHD included 57 cases (76%) of type Ⅰ, 9 cases (12%) of type Ⅱ, 4 cases (5%) of type Ⅲ and 5 cases (7%) of type Ⅳ LHD, respectively. Among 75 pediatric recipients, 69 cases (53 cases of type Ⅰ, 8 type Ⅱ, 4 type Ⅲ and 4 type Ⅳ) underwent the left hepatic duct-jejunum Roux-en-Y anastomosis, 1 case received common bile duct-jejunum Roux-en-Y anastomosis (type Ⅳ), and 5 cases underwent the left hepatic duct-common bile duct end-to-end anastomosis (4 cases of type Ⅰ and 1 type Ⅱ). Postoperative biliary complications occurred in 6 cases (8%), including 3 cases of biliary anastomotic stenosis, 2 cases of biliary anastomotic leakage and 1 case of bile leakage on the hepatic resection surface. Among 6 recipients, 4 cases were classified as type Ⅰ and 2 cases of type Ⅲ LHD. No significant difference was observed in the incidence of biliary complications between typical type and anatomical variant type of LHD (all P > 0.05). Among 3 recipients with biliary anastomotic stenosis, 2 cases underwent percutaneous transhepatic cholangial and drainage (PTCD) and 1 case repeatedly received biliary-intestinal anastomosis. Two cases of biliary anastomotic leakage underwent PTCD and 1 case of bile leakage on the hepatic resection surface received local drainage. All 6 children survived after treatment. Conclusions Anatomical variation of LHD can be observed in 24% of donor livers, and type Ⅱ accounts for the highest proportion of 12%. Prior to donor liver splitting, routine cholangiography and fine biliary anastomosis may effectively lower the incidence of biliary complications. The incidence of postoperative biliary complications is not significantly associated with the anatomical classification of LHD.

ObjectiveTo explore the potential mechanism of moxibustion at Guanyuan （CV 4） in delaying skin photoaging. MethodsThirty-two male Wistar rats were randomly divided into four groups， namely blank group， model group， vitamin E group， and moxibustion group， with 8 rats in each group. Except for the blank group， dorsal skin of rats were exposed to ultraviolet （UV） radiation to establish a skin photoaging model. One week after modeling， the moxibustion group received moxibustion at "Guanyuan （CV 4）" once a day， five days per week； the vitamin E group received vitamin E （25 mg/kg·d） once a day by gavage， five days per week； the blank group， model group， and moxibustion group received an equivalent volume of normal saline via gavage； the intervention lasted for 7 weeks. After 7 weeks， dorsal skin tissues were collected to analyze the following indicators， such as skin tissue moisture content， histomorphological changes using hematoxylin-eosin （HE） staining， Collagen Ⅰ and collagen Ⅲ content using ELISA. Malondialdehyde （MDA）， glutathione peroxidase （GSH-Px）， superoxide dismutase （SOD）， hydrogen peroxide （H₂O₂）， and catalase （CAT） activity in skin tissue were dectected. Western Blot was used to determin autophagy-related proteins， including microtubule-associated protein 1A/1B-light chain 3 （LC3）， polyubiquitin-binding protein （p62）， and autophagy-specific gene （Beclin-1）； LC3， p62， and Beclin-1 mRNA expression was detected via qRT-PCR， and autophagosome formation was observed using transmission electron microscopy （TEM）. ResultsHE staining showed that the epidermal structure in the blank group was orderly and evenly thick， while the model group exhibited uneven epidermal thickness. In the moxibustion group， the epidermis was well-structured， smooth， and uniform， with densely arranged dermal layers； the epidermis in the vitamin E group was thicker than that in the model group. Compared with the blank group， the model group exhibited decreased skin moisture content and reduced level of Collagen Ⅰ and collagen Ⅲ， reduced SOD， CAT， and GSH-Px activity in skin tissue， increased H₂O₂ and MDA activity， elevated p62 protein and mRNA expression， reduced LC3 and Beclin-1 protein and mRNA expression （P＜0.05 or P＜0.01）. Compared with the model group， the moxibustion group showed significant improvement in all these indicators （P＜0.05 or P＜0.01）； whereas the vitamin E group did not show a statistically significant difference in Collagen Ⅰ and collagen Ⅲ levels （P＞0.05）. TEM results showed that， compared with the blank group， the model group had atrophic skin cells， extensive mitochondrial vacuolization， and degraded cellular structures； the moxibustion group exhibited crescent- or cup-shaped autophagosomes with a significantly increased number of autophagosomes per unit area， whereas the vitamin E group showed less improvement than the moxibustion group. ConclusionMoxibustion at "Guanyuan （CV 4）" may alleviate skin photoaging by regulating oxidative stress imba-lance， modulating cellular autophagy， and promoting collagen synthesis， thereby slowing the aging process of the skin.
