ABSTRACT

Liver failure is a common severe liver disease syndrome in clinical practice and is one of the critical medical conditions in internal medicine. Massive hepatocyte death is the main pathological feature of liver failure, and its core mechanisms include endotoxin, immune response, and inflammatory cascade reaction. Effective regeneration of hepatocytes to compensate liver function is the physiological basis for promoting the good prognosis of liver failure, which directly affects the prognosis and quality of life of patients with liver failure. It has been found in clinical practice that liver failure patients with a low serum level of cholesterol tend to have an extremely high mortality rate, but as an index of hepatocyte anabolism, the association between cholesterol and hepatocyte regeneration has not been taken seriously. Based on the association between cholesterol and liver regeneration, this article reviews its significance and potential value in the clinical treatment of liver failure, in order to understand the pathogenesis of liver failure from another perspective and provide new ideas for the diagnosis and treatment of liver failure and the development of drugs.

ABSTRACT

Liver failure is a common critical medical disease, and extensive liver cell necrosis within a short period of time exceeds the regeneration capacity of liver cells and thus results in an extremely high fatality rate. Promotion of effective liver regeneration is the key to antagonizing liver failure. Recent studies have shown that bile acid, farnesoid X receptor (FXR), and intestinal microecology play an important role in liver failure and liver regeneration. This article reviews the association between bile acid, FXR, and intestinal microecology and their role in liver failure and liver regeneration, so as to provide new ideas for the treatment of liver failure in clinical practice.

ABSTRACT

Liver failure is a syndrome of severe liver diseases commonly seen in clinical practice, and it has a high mortality rate and thus becomes one of the critical diseases in internal medicine. Massive hepatocyte death and the extent of hepatocyte death exceeding the liver’s regenerative capacity are considered the core events in the development and progression of liver failure, and direct injury and immune-mediated inflammatory injury are the two main factors in this process. An increasing number of evidence has shown that host immune response and inflammatory cascade play an important role in the pathogenesis of liver failure. This article reviews the mechanism of action of immunoregulation (congenital and adaptive) and inflammatory injury (inflammation inducers, receptor cells, and inflammatory mediators) in the process of hepatic failure, as well as the interactions between immune response and immune cells and between inflammatory response and inflammatory factors, in order to help understand the pathogenesis of liver failure and provide new ideas for the diagnosis and treatment of liver failure and drug research and development.

ABSTRACT

OBJECTIVE:To study the protective effect of tadehaginoside(TA)on liver fibrosis model mice induced by carbon tetrachloride(CCl4),and to investigate its mechanism. METHODS :Kunming mice were randomly divided into normal group , model group ,colchicines group (positive control ,0.2 mg/kg),TA low-dose ,medium-dose and high-dose groups (3,6,12 mg/kg),with 10 mice in each group. Those groups were intraperitoneally injected with 10% CCl4-olive oil solution (5 mL/kg)to induce liver fibrosis model twice a week ,for consecutive 8 weeks;except that ,the normal group was intraperitoneally injected with olive oil. From 3rd week ,the mice in each administration groups were given relevant medicine intragastrically ,normal group and model group were given constant volume 2% sodium carboxymethylcellulose solution intragastrically ,once a day ,for consecutive 6 weeks. The contents of ALT ,AST,HA and IL- 6 in serum of mice were test ed by ELISA. The contents of Hyp , SOD,MDA and GSH-Px in liver tissues were detected by spectrophotometry. mRNA expression of Col- Ⅰ,TIMP-1 and TIMP-2 in liver tissue was detected by RT-PCR. The protein expression of MMP- 2 and TGF-β1 in liver tissue was detected by Western blotting. RESULTS : Compared with normal group,the contents of ALT,AST,HA,IL-6,MDA and Hyp,the mRNA expression of Col- Ⅰ,TIMP-1 and TIMP- 2,as well as the protein exp ression of MMP- 2 and TGF-β1 were increased significantly ,while the contents of SOD and GSH-Px were decreased significantly (P<0.01). Compared with model group,the contents of ALT ,AST,HA,IL-6,MDA and Hyp ,the mRNA expression of Col- Ⅰ,TIMP-1 and TIMP- 2,as well as the protein expression of MMP- 2 and TGF-β1were decreased significantly ,while the contents of SOD and GSH-Px were increased significantly(P<0.05 or P<0.01). CONCLUSIONS :TA has a significant protective effect on liver tissue and anti-fibrosis effects in liver fibrosis model mice ,the mechanism of which may be associated with inhibiting lipid peroxidation and collagen synthesis , down-regulating the mRNA expression of Col- Ⅰ,TIMP-1 and TIMP- 2 as well as the protein expression of MMP- 2 and TGF-β1.

ABSTRACT

Objective To study the morphological changes of external eyes before and after epicanthoplasty combined with blepharoplasty and to explore a simple and efficient method to correct epicanthus. Methods A total of 120 eyes in 60 patients were operated on with the inverted L-sharp epicanthoplasty combined with double-eyelid blepharoplasty and the follow-up began 2 months after the surgery. The height and physiognomic length of the eyelid and the length and angle of the eyelash were measured and compared with preoperative meansurements, as well as the distance of the inner canthus. The ratios between the inner-canthus distance and the physiognomic eyelid breadth and the diameter of eyebrow and eye were also described. Results The contours of the eyelid fissure and the double-eyelid were natural and the surgical scare was seen unconspicuous 3 months after the operation. Changes in the palpebral fissure , the angel and length of the exposed eyelash were all significantly different by paired-sample t test (P < 0.01). The vertical and horizontal lines through the entocanthion and the vertical line through the gnomic ectocanthion combined with the horizontal line through the brow ridge formed a square structure. Conclusions This inverted L-shape epicanthoplasty combined with blepharoplasty may be effective in reconstructing the contours of the entocanthions as well as the shape of the double eyelids. It can also achieve better cosmetic effects in the proportional relation between the eyes and eyebrows. Therefore, it deserves clinical promotion.

This study is to investigate the effect of osthol on osteoclasts' activity, bone resorption as well as apoptosis in vitro, and explore the mechanism of osthol in preventing osteoporosis. Osteoclasts were separated from long-limb bones of new born rabbits, cultured in 24-well plate with glass slices and bone slices, and treated by 1 x 10(-5) mol x L(-1) osthol. Osteoclasts were identified by observing live cells with phase contrast microscope, HE staining, TRAP staining and toluidine blue staining of bone resorption pits. The numbers of bone resorption pits were counted as well as the surface area of bone resorption on bone slice. Osteoclasts were stained with acridine orange to detect the cell apoptosis. The ratio of apoptotic osteoclasts was observed under fluorescence microscope. The gene expression of RANKL, OPG, TRAP and p-JNK1/2 protein expression were examined using real time PCR and Western blotting, respectively. Comparing with the control group without osthol, the rates of apoptotic osteoclasts increased obviously and the number and area of bone resorption pits decreased evidently with 1 x 10(-5) mol x L(-1) osthol. There is significant difference between control group and experiment group treated by 1 x 10(-5) mol x L(-1) osthol. Therefore, the osthol through RANK+RANKL/TRAF6/Mkk/JNK signal pathway inhibits the osteoclasts activity, enhances osteoclasts apoptotic and inhibits the bone resorption.

ABSTRACT

Objective To explore a new surgical treatment for severe inverted nipple and to reduce the possibility of recurrence. Methods Two opposite long six-side polygon de-epithelialized areas were designed within the range of areola on both sides of the nipple. The four sides in lateral portion were dissected and two wedge-shaped dermal and glandular tissue flaps were created, completely releasing the contractive fiber causing nipple retraction while reserving breast ducts. The flaps were reversed 180 degrees through the tunnel bilateral sides of breast ducts to support the nipple. It was tracted for 3-4 weeks by series 7 needle penetrating the nipple basis. Results All the 14 patients were followed up for 3-18 months, and they were satisfied with the appearance and the aesthesia of the nipple and no recurrence was observed, breast-feed function reserved in 2 cases after childbirth. Conclusions This operation is easy to perform with satisfying aesthetic outcome and breast-feed function remaining.It is an ideal method for correcting serious inverted nipple.

ABSTRACT

Objective To evaluate medical chemistry adhesive in tension-free herniorrhaphy for inguinal hernia. Methods In this study, 100 patients with primary unilateral inguinal hernia were assigned to study group ( n = 50) and control group ( n = 50) during Jun. 2009 and Dec. 2009. Medical chemistry adhesive (n-butyl-2-cyanoacrylate, NBCA) was used in Lichtenstein tension-free hernia repair in study group and suture procedure was used in control group. Patient demographics, operation time,postoperative length of stay, visual analogue scale ( VAS ) score 24 hours after surgery, incidence of postoperative chronic pain and hematoma, recurrence rate, and other complications were compared between the two groups. Results The duration of follow-up ranged from 12 months to 18 months. There were no recurrences or wound infection in the two groups. In study group, no patient complained of chronic pain postoperatively, whereas in the control group, 6 patients ( 12% ) had a significant chronic pain. In study group, 2 patients (4%) had local hematoma after operation, whereas there were 8 ( 16% ) in the control group ( P < 0. 05 ). There were no significant differences between the 2 groups in postoperative length of stay ( P > 0. 05 ), but the operation time and postoperative VAS score in study group ( 38 ± 5 min and 2. 5 ± 0. 6)were lower than in the control group (42 ± 5 min and 2. 8 ± 0. 8 ), ( P < 0. 05 ). Conclusions Application of medical chemistry adhesive in tension-free herniorrhaphy for inguinal hernia is associated with less postoperative pain, lower incidence of hematoma, less postoperative chronic pain and shorter operation time.

ABSTRACT

BACKGROUND: Bone marrow mesenchymal stem cells (MSCs) have multi-differentiation potential. In the acute wound, MSCs have been demonstrated to have the potential for differentiating into skin cells. However, there are few reports regarding its differentiation in diabetic wound.OBJECTIVE: To observe the feasibility of differentiation of MSCs into the cells of skin appendages under the microenvironment of diabetic wound.METHODS: MSCs were isolated from the bone marrow of rats, purified and cultured. Third or fourth passage MSCs were selected and labeled with 5-bromodeoxyuridine (5-BrdU). The rats were injected intraperitoneally with single administration of streptozocin to establish diabetes model. After 2 weeks, a round skin wound was made on the dorsal back of rats. BrdU-labeled MSCs at a density of 1×10~9/L were injected into the wound of the rats. The specimens were harvested from the wound tissues to prepare sections at 2 and 3 weeks after transplantation, followed by immunohistochemical staining with BrdU or keratin. RESULTS AND CONCLUSION: BrdU positive cells aggregated in the epidermis, dermis and hypodermia. Some positive cells appeared in the sebaceous glands and sebaceous duct cells and expressed keratin simultaneously in serial sections. During diabetic wound healing, MSCs have the potential to differentiate into the cells of the skin appendages.
