Objective To study whether Clonorchis sinensis eggs were involved in the pathogen esis of gallbladder stones.Method From March to August 2011,the gallbladder stones from 183 patients were studied using microscopic examination and FTIR spectroscopy.Twenty egg-positive and 20egg-negative gallbladder stones found under microscopic examination were chosen randomly and analyzed through real-time fluorescent PCR and scanning electron microscopy.Results Eggs were detected in 118 of 183 gallbladder stones.The eggs were preliminarily diagnosed as Clonorchis sinensis eggs using the morphologic characteristics under light microscope.The results of real-time fluorescent PCR showed eggs in the gallbladder stones were Clonorchis sinensis eggs.The 118 egg-positive gallbladder stones were composed of 97 pigment stones,21 mixed stones and no cholesterol stones.The detection rate of Clonorchis sinensis eggs in pigment stones were the highest among the three types of gallbladder stones (P＜0.001).The 20 egg-positive stones were observed by scanning electronic microscopy:dozens or even hundreds of Clonorchis sinensis eggs were visible under 400 times magnification; and a dozen or even dozens of Clonorchis sinensis eggs and the surrounding particles were adherent to or parceled with each other under 1000 times magnification.While under 3000 times magnification,uneven texture was seen on the surface of eggs with pieces being shed from some eggs.Some eggs were hollow or without cover.Most of them were adherent to or wrapped with amorphous particles or mucoid matter.Conclusions A large amount of Clonorchis sinensis eggs were detected in gallbladder stones.Clonorchis sinensis eggs were associated with the formation of gallbladder stones,especially with pig ment stones.

Objective A systematic study to classify mixed gallbladder stones to determine their relationship with Clonorchis sinensis infection.Methods 349 consecutive patients with mixed gallbladder stones were enrolled into this study and their gallstones were studied.The material composition of gallbladder stones was analyzed using Fourier Transform Infrared spectroscopy,and the distribution and microstructure of the material components were studied using Scanning Electron Microscopy.The composition and distribution of the elements were analyzed by an X-ray energy spectrometer.Gallbladder stones were classified accordingly,and the stones were then grinded for microscopic examination.The stones were divided into two groups based on the results of detection of clonorchis sinensis eggs.Patients were also divided into two groups according to the patients' region (high-incidence and low-incidence regions of Clonorchis sinensis infection).The diversity of the subtypes of mixed gallbladder stones was compared.Results 14 subtypes were found,including Bilirubinate-calcium carbonate mixed stones (n =134),Cholesterol-bilirubinate mixed stones (n =87),Bilirubinate-phosphate mixed stones (n =39),Cholesterol-calcium carbonate mixed stones (n =30),Cholesterol-bilirubinate-calcium carbonate mixed stones (n =15),etc.Bilirubinate-calcium carbonate mixed stones were the main subtype of egg-positive mixed gallbladder stones and the patients were from high-incidence regions.Cholesterol-bilirubinate mixed stones were the main subtype of egg-negative mixed gallbladder stones and patients were from low-incidence regions.The differences of the subtypes constituent between the high-incidence and low-incidence regions groups were significant (P ＜ 0.05),and between the egg-positive and egg-negative groups were also significant (P ＜ 0.05).Conclusions The most common subtypes of mixed gallbladder stones were bilirubinate-calcium carbonate mixed stones,while the second was cholesterol-bilirubinate mixed stones.Clonorchis sinensis infection was mainly associated with Bilirubinatecalcium carbonate mixed stones.

Objective To explore the mechanism of cytokines for the scars,and to study the effect of platelet derived growth factor(PDGF)on the biological behavior of fibroblasts in scars.Methods Fibroblasts of scars and normal skins were cultured in vitro.The results were observed and analyzed by light inverted microscopy(LM),and 3-(4,5-dimethyl-thiazol-2-yl)-2,5 ciphenyl tetrazolium bromide (MTT)assay.The effects of PDGF on the biological behaviors of fibroblasts of scars were also determined. Results In vitro study,using LM,FCM and MTT assay,showed that proliferation of fibroblasts were inereased significantly when PDGF was added to the cultures,as compared to the control groups.Conclusions PDGF can increase fibroblast proliferation.These results demonstrate that PDGF is beneficial for wound healing at early stage.

ObjectiveTo investigate the relationship between intramural gallstones and intraluminal gallstones. MethodsIn this present study, the control study was applied to analysis on the gallstones from 116 cholecystolithiasis patients with intramural gallstones as well as intraluminal gallstones. All the patients were from the general surgery department and accepted gallbladder-preserving cholecystolithotomy during 2009.02-2009.08. Meanwhile, 171 patients with intraluminal gallstones were investigated the clinical traits; and gallstones from them were analyzed with FT-IR and microsopic examination. ResultsThe results showed the coincidence rate of stone type was 97.4％, and it was mainly pigment gallstones and mixed gallstones in 116 cases; the coincident detection rate of clonorchis sinensis eggs was 98.3 ％, and it was much higher in the pigment gallstones and mixed gallstones than that in the cholesterol gallstones. The ratio of pigment gallstones from the 116 patients group was higher than the 171 patients group, and the detection rate of C. sinensis eggs of the two groups had no statistical difference (P＞0.05). ConclusionsThe stone type of intramural gallstones was mainly pigment gallstones and mixed gallstones. Intramural gallstones and intraluminal gallstones were homologous.

Objective To develop a classification of gallbladder stones,to analyze the clinical characteristics of each type of stone and to provide a theoretical basis for the formation of different types of gallbladder stones.Method 925 consecutive patients with gallbladder stones were enrolled and their gallstones were studied.The material composition of the gallbladder stones was analyzed using fourier transform infrared spectroscopy and the distribution and microstructure of the material components were observed using scanning electron microscopy.The composition and distribution of the elements were analyzed by an X-ray energy spectrometer.Gallbladder stones were classified accordingly.Results The gallbladder stones were classified into 8 types and more than ten subtypes,including cholesterol stones (n =334),pigment stones (n =246),calcium carbonate stones (n =167),phosphate stones (n =14),calcium stearate stones (n =11),protein stones (n =3),cystine stones (n =1) and mixed stones (n =149).Mixed stones were those stones with two or more than two kinds of material components and the content of each component was similar.A total of 11 subtypes of mixed stones were found in this study.Conclusion The systematic classification of gallbladder stones indicated that different types of stones had different characteristics in terms of infrared spectrogram,microstructure,elemental composition and distribution,thus providing an important basis for the mechanistic study of gallbladder stones.

BACKGROUND: Nerve growth factor is secreted and synthetized by a variety of cells, such as inflammatory calls and repairing calls, its biological effects are diverse and closely related to the process of wound repair, but its mechanism is not yet clear.OBJECTIVE: To observe the influence of nerve growth factor on the biological characteristics of scar fibroblasts.METHODS: Eight clinical surgical resection specimens, including 5 face and neck hyperplastic scar or keloid specimens, did not receive any treatment; three were prepuce specimens following circumcision (normal tissue). By use of tissue block method, the scar and normal skin fibroblasts were cultured, followed by digestion passage. The scar tissue and normal tissue flbroblasts at 3-6passages in the logarithmic phase were seeded in 96-well plate and divided into the experimental group (scar flbroblest group) and the control group (normal skin fibroblasts group), with two parallel holes in each group were added with 3,33, 0.33 mg/L nerve growth factor, 50 μL. Inverted microscope was used to observe fibroblast morphology. At 24, 48, 72 hours after culture, the absorbanca value was measured using MTT. Fibroblast DNA content and cell apoptosis were determined by flow cytometry.RESULTS AND CONCLUSION: The fibroblasts were adherent cells, the scar and normal skin tissues were shown to cell free out of tissue block and gradual expansion at 4-6 days after incubation. Compared with normal skin fibroblasts, the pathological scar fibroblasts became larger, irregular shape and arrangement. MTT results showed that nerve growth factor could promote the normal and hypertrophic scar fibroblasts growth, which becomes more apparent. Flow cytometry results showed that by adding nerve growth factor, the percentage of scar fibroblasts at proliferating S-G_2-M phase was higher than that in the control;group; with a Iower level of apoptosis. It is indicated that nerve growth factor plays an obviously promoting role on normal and scar skin fibroblasts growth and proliferation, especially on the scar skin.

Objective To study the relationship between Clonorchis sinensis infestation and different types of gallbladder stones.Methods From May 2011 to September 2014, 1 052 cases of gallbladder stones were collected from the Department of General Surgery at The Sixth People's Hospital of Nansha, Guangzhou.These stones were first grinded for microscopic examination and divided into two groups based on the results of detection of Clonorchis sinensis eggs.They were then analyzed by FTIR spectroscopy to identify the type of gallbladder stones.Some stones were also chosen randomly for observation under scanning electron microscope (SEM).Results Clonorchis sinensis eggs were found in 300 stones and among these, the number and proportion of cholesterol, bile pigment, calcium carbonate, mixed and other types of stones were 28 (9.3％), 102 (34.0％), 102 (34.0％), 50 (16.7％), and 18 (6.0％), respectively.In the 752 egg-negative stones, the number and proportion of the above five types of stones were 414 (55.1％), 132 (17.6％), 66 (8.8％), 94 (12.5％), and 46 (6.1％), respectively.Observation under SEM showed a lot of tiny particles were absorbed on the mesh of the superficial texture of the Clonorchis sinensis eggs, which were also adherent to the bilirubin particles, calcium stearate crystals, phosphate, calcium stearate and protein particles.Conclusions The main types of egg-positive stones were bile pigment and calcium carbonate stones, while cholesterol stone was the main type of egg-negative stones.Clonorchis sinensis infestation was associated mainly with bile pigment and calcium carbonate stones.

Objective To evaluate the outcomes of distal leg and foot-ankle reconstruction with rotated single pedicel reverse sural neurocutaneous island flaps. Methods From June 2011 to January 2016, seventeen distal leg and foot-ankle defects cases repaired with rotated single pedicel reverse sural neurocutaneous island flap were analyzed retrospectively. In this study, 13 cases were male, and 4 cases were female. Age ranged from 25 to 65 years old, with an average age of 42.0 ± 8.3 years. Seven cases were distal leg defects, 3 cases were ankle defects, 3 cases were heel defects, and 4 cases were acrotarsium defects; all cases had bone and tendon exposure. The defects ranged from 5.0 cm × 7.0 cm-6.0 cm × 12.0 cm. The flap size ranged from 5.0 cm × 7.0 cm-8.0 cm × 15.0 cm. Results All 17 cases survived completely, without thanatosis, blisters and vascular crisis. The follow-up period was 12-48 months, and the mean was (20.0 ± 11.1) months. The color and elasticity of the flaps was excellent, with satisfactory appearances. Function and appearance of donor sites was not affected. Conclusions The rotated single pedicel reverse sural neurocutaneous island flaps have no injury on main nerves and arteries. The flaps have wide rotation angle and less invalid fold in the pedicel. The simple operation has satisfactory effects and high survival rate. It is a relatively easy procedure that can be applied toward repairing of distal leg and foot-ankle soft tissue defect.

BACKGROUND: Resistin has been shown to play an important role in the pathogenesis and progression of osteoarthritis. OBJECTIVE: To investigate the correlation between resistin level in serum and synovial fluid and the severity of knee osteoarthritis. METHODS: Seventy-four patients with knee osteoarthritis and 79 healthy individuals were recruited. The Noyes score method was used to assess articular cartilage damage arthroscopically. The severity of knee osteoarthritis was evaluated according to the Western Ontario McMaster University Osteoarthritis (WOMAC) score. The radiographic severity of knee osteoarthritis was assessed by the Kellgren-Lawrence (K-L) grading system. The levels of resistin and cross linked C-telopeptide of type Ⅱ collagen (CTX-Ⅱ) in serum and synovial fluid were determined by ELISA. RESULTS AND CONCLUSION: The resistin level in the synovial fluid was positively correlated with the radiographic severity of knee osteoarthritis, WOMAC pain, WOMAC function, and WOMAC total scores, but showed no correlation with the WOMAC stiffness score. There were no significant correlations between the serum level of resistin and WOMAC total scores, subscale or K-L Grading system in the the osteoarthritis patients. Multiple regression analysis showed that the correlation between the synovial fluid level of resistin and WOMAC scores was of significance after removal of other confounding factors, and the resistin level in the synovial fluid was positively correlated with Noyes scores and CTX-Ⅱ level. These results suggest that the resistin level in the synovial fluid can serve as a potential biomarker reflecting the severity of knee osteoarthritis and cartilage degenerative degree in patients with osteoarthritis.
