Hedgehog(HH),a vital endodermal signal,plays a critical role in the embryonic development of the GI system.During mammalian embryonic development,deficiency of HH signaling leads to gastrointestinal malformations.Nevertheless,normal presence of HH family is also found in the adult gut,and HH signaling now may be important for homeostasis of the gut in such a case.However,many researches revealed that the HH signal's involved in gastrointestinal carcinogenesis and its role is altered in various tumors due to various mechanisms.This review focused on the progress of HH signal pathway in gastrointestinal tumors.

Objective: To analyze the application value of radionuclide myocardial perfusion imaging in the localization and diagnosis for stable angina pectoris in clinical practice. Methods: A total of 70 patients who had been diagnosed with stable angina pectoris (SAP) were enrolled, and all patients underwent ATP-loaded ATP-99Tcm-MIBI (99Tcm-MIBI) myocardial perfusion imaging (MPI) and coronary angiography (CAG) were used to compare the accuracy of MPI imaging in localization and diagnosis for SAP. Results:In the 70 cases of patients with two methods of examination: ①In MPI diagnosis, positive patients were 50 cases, and the positive predictive value of SAP, sensitivity, negative predictive value and specificity were, respectively, 92.0%, 90.2%, 75.0% and 78.9%. There were 45 patients were consistently diagnosed as SAP by the two methods and the total compliance rate was 90.0%. ②in 70 patients, 51 cases were diagnosed as SAP by CAG examination, the positive rate was 72.9%; ③in 50 MPI positive patients, 46 patients were consistent with the results of CAG diagnosis, and the positive rate was 92.0%. The difference between the two methods was statistically significant (x2= 5.72, P<0.05). Conclusion: 99Tcm-MIBI myocardial perfusion imaging can be used as a gatekeeper in patients with stable angina pectoris, and has high application value in the location and diagnosis for stable angina pectoris. The diagnosis and treatment links of stable angina pectoris can save costs and provide a reliable evidencet for clinical practice.

It is rare that large mixed tumors of salivary gland located in the nose and uvula. The patient who had mixed tumors of salivary gland at nose found exophytic growth tumor for half a year. The other patient who had mixed tumors of salivary gland at uvula felt swallowing foreign body sensation for one year, and dysphagia for one month. After surgical resection, the symptoms disappear.

Objective To investigate the surgical method and clinical curative results of acetabulum top compression fractures with sea gull sign. Methods Data of 14 patients who had acetabulum top compression fractures with sea gull sign were retrospectively analyzed and were accepted surgical therapy and followed up. There were 5 females and 9 males, aged from 28 to 71 years (average, 49.9 years). The pre-operative time was from 4 to 14 days (average, 9 days). Letournel-Judet fracture classifica-tion:eight cases for the anterior column+posterior semi-transverse, six cases for a simple anterior column. Three patients with lum-bar compression fracture, two patients with tibial plateau fracture, one patient with multiple rib fractures. All patients were accept-ed open reduction and bone graft and internal fixation through ilioinguinal approach or ilioinguinal approach+Kocher-Langenbeck approach. The quality of fracture reduction was assessed according to the Matta reduction criterion after operation. The hip func-tion was evaluated according to Matta. Results 14 patients were followed up from 6 to 60 months (average, 36 months). All pa-tients reached bone healing;healing time was from 3 months to 4 months (average, 3.4 months). According to the Matta reset stan-dard after operation, there were 6 excellent cases, 5 good cases, 2 fair cases, 1 poor case, the excellent and good rate was 78.5%(11/14). The Matta was from 10 to 18 scores (average, 16.4 scores), 5 excellent cases, 5 good cases, 3 fair cases, 1 poor case, the ex-cellent and good rate was 71.4%(10/14). Traumatic arthritis occurred in 3 patients. Pain was serious in two patients and disap-peared after total hip joint replacement. Pain was mild for one patient and disappeared after accepted non steroidal painkiller. One patient had heterotopic ossification after operation, which was not treatmented because of no obvious symptom. Conclusion The appropriate operation time of acetabular roof compression fracture with sea gull sign was from 5 to 10 days after fracture, which was no more than two weeks had best. Through ilioinguinal approach or ilioinguinal approach+Kocher-Langenbeck approach, the articular surface could be reduced excellent and got sufficient bone graft. The clinical efficacy was satisfactory after operation.
