Objective To evaluate and compare the clinical effects of forward and reverse anterior cruciate ligament (ACL) reconstruction through the arthroscopy. Methods From April 2008 to August 2009,97 cases with simple ACL injures were treated with eight strands of hamstring tendons in way of two-bundle and four-tunnel reconstruction. The patients were randomly divided into two groups according to the number of hospital admissions: odd numbers (A group, 47 cases) were treated with forward double-bundle reconstruction and even (B group,50 cases) were treated with reverse. The grafts were fixed with a suspension technique by mini-plates and mini-buttons. Mean follow-up exceeded one year. The function of knee joint were assessed by the IKDC, Lysholm and Tegner rating scale. Results Mean follow-up was 13.71 months.At the last follow-up, 2 patients in A group had a 10°extension deformity and 5 had a less than 15° flexion limitation. All patients in B group showed normal knee extension, and 4 had a 5° flexion limitation. According to Lachman test, there were one case with one plus positive and one with two plus positive in A group,and one with two plus in B. KT-1000 examination (30° flexion and 30 N) showed the side to side mean difference of anterior knee laxity was (1.04±1.11) mm in A group and (0.86±1.12)mm in B. According to objective IKDC evaluation, the results were graded as normal or nearly normal in 46 patients in A group and 48in B. There were no statistical differences in the IKDC, Lysholm, and Teguer scores between two groups.Conclusion Forward or reverse ACL double-bundle reconstruction with eight strands of hamstring tendons can both restore knee stability, and there is no significant deviation between the two techniques.

Objective The purpose of this study is to evaluate the relevance of the recovery of proprioception function and the reservation of residual torn ligamentous fiber in the anterior cruciate ligament (ACL)reconstruction.Methods A retrospective study was carried out in 65 cases of ACL injury,who were treated with double-bundle ACL reconstruction and tibial remnant preservation and tensioning.All the patients were divided into four groups according to the degree of tibial residual fiber observed in the operation,no residual fiber was found(Group A),the length of the residual fiber was less than one third of the normal ACL(Group B),the length of the residual fiber was more than one third less than two thirds of the normal (Group C),the length of the residual fiber was more than two thirds of the normal(Group D).After one year follow-up,the passive angle reproduction test was performed with magnetic angle instrument in 3 flexion ranges(flexion of 90°-60°,60°-30°,and 30°-0°).All the results were contrasted among the four groups by statistical methods.Results In the passive angle reproduction test of the 3 flexion ranges,Group A and B showed a significant difference between the test side and control side(P＜0.05),and Group C showed a significant difference between the test side and control side at the flexion of 30°-0°(P＜0.05),but Group D showed no significant difference at the 3 flexion ranges(P＞0.05).Conclusion During double-bundle ACL reconstruction,with the reservation of tibial residual tom ligamentous and tensioning may have a good effect on the recovery of proprioception function of the knees,which ensure a better functional outcome in the reconstructed knee.

Injury to anterior cruciate ligament (ACL) is the most common lesions of the knee joint. Reconstruction of ACL has been the primary treatment for the instability of the knee. Compared with the traditional reconstruction with patellar tendon, the hamstring tendon has many advantages, such as less damage to the donor site and less incidence of antero-patellar or kneeling pain. This paper highlights the basic and clinical research on ACL reconstruction.

ObjectiveTo investigate the effect of Zuoguiwan on pancreatic islet function in offspring of gestational diabetes mellitus （GDM） maternal rat model and explore the mechanisms of Zuoguiwan in improving pancreatic islet function based on postpartum pancreatic regeneration. MethodHealthy female SD rats with normal blood glucose levels were paired with male rats in a 2∶1 ratio and housed together. Pregnancy was confirmed based on vaginal plugs or vaginal smears. The pregnant rats were divided into the following groups： normal group， model group， insulin group （insulin Detemir， 20 U·kg^-1）， low-dose Zuoguiwan group （1.89 g·kg^-1）， and high-dose Zuoguiwan group （3.78 g·kg^-1）. The GDM rat model was induced using streptozotocin in rats except for those in the normal group. The model was confirmed by blood glucose testing in the maternal rats. Except for the normal and model groups， the other groups received daily administration of corresponding treatments. At 21 days after birth， fasting blood glucose （FBG） and fasting serum insulin （FINS） levels were measured in 6 offspring from each group. The homeostasis model assessment of insulin resistance （HOMA-IR） was calculated， and an oral glucose tolerance test （OGTT） was performed on additional 12 offspring from each group. Blood samples were taken from the abdominal aorta of the offspring at postnatal day 22， and enzyme-linked immunosorbent assay （ELISA） was used to measure insulin， glucagon （GC）， pancreatic polypeptide （PPY）， and somatostatin （SS） levels in the serum. Hematoxylin-eosin （HE） staining was performed to observe pathological changes in the pancreatic tissue of the offspring. Immunofluorescence （IF） was used to observe the area and structure of the pancreatic islets. Western blot was used to detect the expression of key proteins involved in the development and functional expression of pancreatic β-cells， namely pancreatic and duodenal homeobox factor 1 （Pdx1）， Nkx6.1， and Glucose transporter 2 （Glut2）. ResultCompared with the normal group， the model group showed significant increases in FBG and FINS levels， and HOMA-IR （P<0.01）. Compared with the model group， the insulin group showed significant decreases in FBG levels and HOMA-IR （P<0.01）， the low-dose Zuoguiwan group showed a significant decrease in FBG levels （P<0.05）， and the high-dose Zuoguiwan group showed significant decreases in FBG and FINS levels， and HOMA-IR （P<0.01）. Compared with the normal group， the model group showed significant increases in OGTT 60-min blood glucose levels and AUC index （P<0.05， P<0.01）. Compared with the model group， the high-dose Zuoguiwan group showed significant decreases in OGTT60-min blood glucose levels and area under the curve（AUC） index （P<0.05， P<0.01）. HE staining of pancreatic tissue showed that compared with the normal group， the model group had a reduced number of islets and a loose arrangement of acinar cells. Compared with the model group， the groups with drug treatment showed increased number of islets and a compact arrangement of acinar cells. Compared with the normal group， the model group had significantly increased levels of insulin， GC， PPY， and SS in the serum （P<0.01）. Compared with the model group， the low-dose and high-dose Zuoguiwan groups and the insulin group showed significantly decreased serum levels of insulin， GC， PPY， and SS （P<0.05， P<0.01）. IF results showed that compared with the normal group， the model group had a significantly lower positive rate of insulin （P<0.05）. Compared with the model group， the low-dose and high-dose Zuoguiwan groups showed a significant increase in the positive rate of insulin （P<0.05）. There was no significant difference in the positive rate of GC among the groups. In terms of the proportion of insulin and GC in individual islets， compared with the normal group， the model group showed a significant decrease in the proportion of insulin （P<0.01） and a significant increase in the proportion of GC （P<0.01）. Compared with the model group， the low-dose and high-dose Zuoguiwan groups showed significantly increased proportion of insulin （P<0.01） and significantly decreased proportion of GC （P<0.01）. Compared with the normal group， the model group showed significantly decreased expression levels of Pdx1， Nkx6.1， and Glut2 proteins in the pancreatic tissue of GDM offspring （P<0.05）. Compared with the model group， the insulin group and the low-dose Zuoguiwan group showed significant increases in the expression levels of Pdx1 and Nkx6.1 proteins in the pancreatic tissue of GDM offspring （P<0.05）， and the low-dose and high-dose Zuoguiwan groups showed significant increases in the expression levels of Glut2 protein （P<0.05）. ConclusionZuoguiwan can promote pancreatic islet development in offspring of GDM maternal rat model， improve pancreatic islet morphology and function， and alleviate insulin resistance. Its mechanism of action may be related to the regulation of Pdx1， Nkx6.1， and Glut2 protein expression in the pancreatic tissue of offspring.

ObjectiveThis paper aims to investigate the potential molecular biological mechanism of Buyang Huanwu Tongfeng decoction in treating hyperuricemia and gouty arthritis by network pharmacology and molecular docking technology and preliminarily verify the mechanism through animal experiments. MethodsThe active ingredients and targets in the Buyang Huanwu Tongfeng decoction were obtained by the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） and ETCM databases. The DisGeNET and GeneCards databases were utilized to acquire disease targets associated with hyperuricemia and gouty arthritis. These disease targets were then intersected with drug targets to identify key targets. The R language ClusterProfiler package and Python were employed for conducting gene ontology（GO） enrichment analysis and Kyoto encyclopedia of genes and genomes（KEGG） enrichment analysis. The regulatory network diagram of the drug-key target-function-pathway was visualized using Cytoscape 3.9.1 software， and the protein-protein interaction （PPI） network for key targets was depicted. Finally， the hub gene was determined through topological analysis. Auto Dock， PyMOL， and other software were used for molecular docking to explore the possible therapeutic mechanism of Buyang Huanwu Tongfeng decoction for hyperuricemia and gouty arthritis. In animal experiments， a composite rat model of hyperuricemia induced by intraperitoneal injection of oteracil potassium combined with gouty arthritis induced by the modified Coderre method was established. Through hematoxylin-eosin（HE） staining， uric acid test， enzyme linked immunosorbent assay（ELISA）， Western blot， and real-time polymerase chain reaction（Real-time PCR）， the molecular mechanism and key targets of Buyang Huanwu Tongfeng decoction for treating hyperuricemia and gouty arthritis were observed. ResultsAfter screening and removing duplicate values， 76 active ingredients and 15 key targets were finally obtained. GO enrichment analysis yielded that the treatment of hyperuricemia and gouty arthritis with Buyang Huanwu Tongfeng decoction was significantly associated with acute inflammatory response， astrocyte activation， regulation of interleukin （IL）-8 production， nuclear receptor activity， and binding of growth factor receptor. KEGG pathway enrichment analysis obtained that the key target genes were significantly associated with the IL-17 signaling pathway， advanced glycosylation end/receptor of advanced glycation endproducts（AGE/RAGE） signaling pathway， anti-inflammatory， and other pathways. PPI network indicated that albumin（ALB）， peroxisome proliferator-activated receptor-γ （PPAR-γ）， IL-6， IL-1β， and C-reactive protein（CRP） were the key protein targets. The molecular docking results showed that ALB had the strongest binding force with beta-carotene （β-carotene）. Biochemical results showed that blood uric acid decreased in the Buyang Huanwu Tongfeng decoction groups. HE staining results showed that the low-dose （7.76 g·kg^-1·d^-1）， medium-dose （15.53 g·kg^-1·d^-1）， and high-dose （31.05 g·kg^-1·d^-1） groups of Buyang Huanwu Tongfeng decoction had different degrees of remission， and the remission of the high-dose group was the most obvious. Fibroblastic tissue hyperplasia in synovial joints accompanied with inflammatory cell infiltration， as well as inflammatory cell infiltration in renal tissue of the high-dose group was significantly reduced， followed by the medium-dose and low-dose groups， and the expression of ALB， PPAR-γ， IL-6， IL-1β， and CRP was down-regulated to different degrees. ConclusionBy regulating the targets such as ALB， PPAR-γ， IL-6， IL-1β， and CRP， inhibiting the PPAR-γ/nuclear transcription factor （NF）-κB pathway， and reducing AGEs/RAGE-mediated inflammation， Buyang Huanwu Tongfeng decoction exerts anti-inflammatory and analgesic effects and activates blood circulation and diuresis in the treatment of hyperuricemia and gouty arthritis.
