ObjectiveIn view of the standardization of clinical diagnosis and treatment of the acute abdomen and the inheritance of diagnosis and treatment experience of prestigious veteran traditional Chinese medicine（TCM） doctors， a diagnosis and treatment reasoning algorithm based on association rule mining under incomplete evidence（AMIE）+ random walk was proposed to provide information services and technical support for primary doctors by recommending personalized diagnosis and treatment plans based on medical records. MethodThe experience of diagnosis and treatment of acute abdomen of prestigious veteran TCM doctors and the text data of clinical diagnosis and treatment guidelines of integrated TCM and western medicine were collected to complete the task of knowledge extraction and construct acute abdomen knowledge graph based on Neo4j. On the basis of ontology-supported rule-based reasoning， the rule reasoning based on similar syndromes was used to expand the syndrome combinations whose Jaccard similarity was greater than the threshold in the syndrome recommendation results. The semantic path coverage algorithm was used to calculate the semantic similarity between the symptom nodes. The symptom nodes were divided into 10 categories， and the symptom nodes in the same category were extended. The random walk algorithm was used to search the symptom nodes connected with the syndrome， and the connection rules between the syndrome and symptom nodes were extended to realize the knowledge reasoning of AMIE+ random walk. ResultThe acute abdomen knowledge graph included 1 320 nodes and 2 464 relationships. According to the link prediction evaluation index of knowledge reasoning， the reasoning results of the three algorithms in the auxiliary diagnosis and treatment of acute abdomen were compared. The AMIE+ random walk algorithm complemented the knowledge graph by extending the similar syndrome connection rules and the syndrome-symptom connection rules. Compared with the knowledge reasoning algorithm based on ontology rules， the area under the curve （AUC） was 15.18% higher and the accuracy was 30.36% higher， which achieved more accurate and effective knowledge inference. ConclusionThis study used knowledge graph technology to visualize the diagnosis and treatment of acute abdomen with TCM and western medicine， assisting primary clinicians in intuitively viewing the diagnosis and treatment process and data relationship. The proposed diagnosis and treatment reasoning algorithm can realize the personalized diagnosis and treatment plan recommendation at the level of "disease-syndrome-diagnosis-treatment-prescription"， which can assist primary doctors in disease diagnosis and treatment and clinical decision-making， contribute to the knowledge sharing and application of diagnosis and treatment experience and clinical guidelines of prestigious veteran TCM doctors， improve the level of primary clinical diagnosis and treatment， and promote the normalization and standardization of the diagnosis and treatment process of acute abdomen with integrated TCM and western medicine.

Objective: To introduce a combined operation for treating chronical peroneal tendon dislocation and to evalu-ate the clinical outcomes of patients. Methods: Data of 12 ankles in 12 patients (male 9, female 3) with chronical peroneal ten-don dislocation who underwent the fibular groove deepening procedure with transposition of the peroneal longus muscle from June 2006 to August 2013 were retrospectively analyzed. The mean age was 24.6±4.3 years (range, 18-34 years), and there were 3 cas-es on left side, 9 on right side. The mechanism of peroneal tendon injury consisted of sports injuries in 8 and sprains in 4. There were 8 cases of flat fibula sulcus and 4 cases of convex. All patients met the inclusion criteria of a painful snapping or popping sen-sation or palpable clicking and positive provocation maneuver and without fracture and were treated with peroneal sulcus deepen-ing and peroneal longus tendon transposition. The duration of preoperative popping and pain symptoms ranged from 12 to 23 weeks, with an average of 16.9±4.0 weeks. All cases were treated conservatively 3-4 weeks before operation and were not effec-tive. The clinical outcomes were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale, visual anologue scale (VAS). Results: Twelve patients were followed up with an average period of 37.3±7.0 (range, 25-50) months. The mean VAS scale score of all patients reduced from 5.6±0.9 to 0.5±0.7 at the latest follow-up. The mean AOFAS scale score improved from 61.4±5.6 to 92.6±4.2 at the latest follow-up. The difference between preoperative and postoperative was statis-tically significant. (t=16.250,-18.475; P=0.000). According to the evaluation of symptom and function scoring system, 10 cases were excellent and 2 cases were good, with an excellent rate of 100%. The mean postoperative return-sport time was 26.42±3.06 weeks (range, 23-32 weeks). All patients healed primarily and no infection, skin necrosis and residual redislocation occurred. The osteotomy healed completely without displacement, which was confirmed by imaging examination in three months postoperation. No patients had intractable pain after surgery, and they were able to perform daily activities at 3 months and physical exercise at 6 months after surgery. No slip occurred in all patients at the latest follow-up. Conclusion The fibular groove deepening procedure with transposition of the peroneal longus muscle can effectively treat chronical peroneal tendon dislocation and obtain good medi-um-term results.

OBJECTIVETo introduce the application and clinical effect of self-made liver fixing device in laparoscopic radical gastrectomy.

METHODSClinical data of 469 patients underwent laparoscopic radical gastrectomy in Nanfang Hospital, Southern Medical University from March 2014 to January 2017 were analyzed retrospectively. In laparoscopic radical gastrectomy, self-made liver fixing device was used to expose surgical field covered by hepatic lobe in gastric lesser curvature and hepatic flexure of colon. Manufacture of the self-made liver fixing device: appropriate length of the catheter was cut according to the size of liver; the lotus suture needle with a thread was put through two catheters to connect them. Then the prepared liver fixing device was sent into abdominal cavity through a 12-mm Trocar hole with needle holder and was fixed on the free hepatic lateral hepatogastric ligament with hemo-lock. Finally the application effect of the liver fixing device was evaluated by reviewing the surgical videos.

RESULTSA mean time of 40.3 seconds was required to complete liver fixing by using the self-made liver fixing device in laparoscopic radical gastrectomy and liver did not slip down in all the cases. Liver secondary manual fixing by assistants was 2 times averagely. Three cases had mild liver injury.

CONCLUSIONThe self-made liver fixing device in laparoscopic radical gastrectomy is easy to operate and can effectively expose sufficient surgical field, with high security and convenient materials.

【Objective】 To investigate the improvement of motor function recovery and the activation of endogenous neural stem cells (eNSCs) via voluntary exercise in mice with hyperlipidemia after intracerebral hemorrhage (ICH). 【Methods】 Four-month-old male Nestin-CreERT2: tdTomato transgenic mice were fed with high-fat diet (HFD) for eight weeks. Type Ⅳ collagenase was micro-injected into the corpus striatum to construct mouse ICH model with the help of stereotaxic apparatus. Voluntary exercise (wheel running) was initiated on the second day after ICH and monitored daily for seven days. Neurological severity score (NSS) and beam walking test were applied to evaluate motor function and coordination. Liver and brain tissues were collected at day 9 after ICH and sliced for staining. Then the Nestin-labeled cells, Ki67⁺, and doublecortin (DCX)⁺ in subventricular zone (SVZ) were counted to evaluate eNSCs activation. 【Results】 ① Compared with those of mice fed by chow diet (CD), the body weight, blood glucose level, concentration of lipid metabolism factors and the number of Nile Red positive cells in liver tissue were significantly higher in HFD-fed mice, confirming hyperlipidemia. ② Compared with the sham group, NSS score increased and the distance of cross-beam walking of ICH mice significantly decreased, showing the deficiency of motor function. It could be rescued by 7-day wheel running, as shown by a lower NSS score and a longer cross-beam walking distance. ③ Compared with the sham group, the number of Nestin⁺/Ki67⁺ cells decreased and Nestin⁺/DCX⁺ cells increased after ICH. After 7-day voluntary exercise, the number of Nestin⁺/Ki67⁺ cells decreased but that of Nestin⁺/DCX⁺ cells further increased significantly. However, compared with ICH, the increase of Nestin⁺/DCX⁺ cells in ICH+Ex was not significant. 【Conclusion】 Short-term voluntary exercise during the acute stage of ICH improved the recovery of motor function and enhance the proliferation of eNSCs in mice with hyperlipidemia. This provides a new idea for further developing ICH accelerated rehabilitation strategy based on eNSCs.

Fungal keratitis is a serious blinding eye disease. The development of fungal infections depends primarily on the interaction of fungal virulence with host immune defense factors. The cornea is considered an immune-privileged organ, and resident macrophages are the main immune cells that respond to the heterogeneity exhibited by the microenvironment with their polarization. In the early stage of infection, macrophages polarize towards M1, which promotes inflammation and facilitates fungal clearance but produces a cellular storm that exacerbates immune damage; in the late stage of infection, macrophages polarize towards M2, which suppresses the inflammatory response and facilitates tissue repair, but may be immunosuppressed or even immune escape to the detriment of pathogen clearance. The balance between pro-inflammatory and anti-inflammatory responses is key to maintaining the functional integrity of the cornea. Current antifungal drug therapy is limited, so it is particularly important to find a therapeutic target for the inflammatory response triggered by the immune response in addition to antifungal therapy. In this review, the functional and phenotypic characterization of macrophage subsets associated with fungal keratitis was reviewed, more in-depth research is needed to explore the specific mechanisms by which macrophage polarization and their impact on fungal keratitis. Targeted regulation of macrophage differentiation based on their phenotype and function could be an effective approach to treat and manage fungal keratitis in the future.
