1.DIAGNOSIS OF CARCINOMA OF BILIARY TRACT BY ERCP: AN ANALYSIS OF 49 CASES
Academic Journal of Second Military Medical University 1982;0(02):-
Twenty-four cases of carcinoma of biliary duct, 6 of carcinoma of gallbladder and 19 of carcinoma of Vater's ampulla are reported. All of those 49 cases were con- firmed by operation and/or pathology.The diagnostic accuracy by endoscopic retragra-de cholangiopancreatography(ERCP)was 85.7%.The radiological appearances of carcinoma of biliary tract under ERCP were described and classified into 3 types, namely obstruction,stricture and polypoid types. The stricture type was further divided into 3 subtypes of occlusive,annular and diffuse stenosis.The obstruction type and occlusive stenosis type were more common. Carcinoma of gallbladder manifested as a constant filling defect with a wide base in the gallbladder, while carcinoma of ampulla as an irregularly bordered space occupying lesion in it, which could obstruct the biliary duct and/or pancreatic duct. The soft rattan-form change in intrahepatic biliary ducts was the characteristic manifestation of malignant tumor of biliary tract.

3.Dilemma and prospect of personalized therapy in non-small cell lung cancer
Cancer Research and Clinic 2010;22(1):23-25
Personalized therapy has became a main method to break through efficacy of chemotherapy in lung cancer. At present, we have got a few progressions in personalized therapy, but which are very limited. This review discourses upon the dilemma and hope of individualized treatment from the following ways:limitation of based on histology type to determine treatment regimens, undecided sequential therapy after failure of TKI as front-line therapy for advanced NSCLC patients with EGFR mutation, clinical study of maintenance therapy and EGFR mutation detection based on peripheral blood being trap or surrogate for tumor tissue to direct personalized TKI therapy.
4.Focusing on the role of conjunctiva goblet cell in maintaining the health of ocular surface
Chinese Journal of Experimental Ophthalmology 2017;35(2):97-101
Ocular surface tissues are vulnerable to various stimuli from the external environment,including microbial invasion,mechanical damage,chemical stimulation,dust,UV light,and allergen stimulation.Conjunctival goblet cells play an important role in maintaining ocular surface self-homeostasis and health.These cells are the only unicellular glands in humans and mammals that are mainly distributed in the epithelium of the digestive tract,respiratory tract,and the ocular surface.Many factors affect goblet cell development and differentiation,especially the newly discovered molecule Spdef,which is a transcription factor found in the ETS family.The main function of conjunctival goblet cells is to secrete mucin to protect and lubricate the ocular surface;however,they also secrete a variety of other bioactive substances.Recent studies have demonstrated that goblet cells are involved in antigen presentation,regulation of dendritic cell phenotype differentiation,and induction of immune tolerance on the mucosa.Many ocular surface diseases,such as dry eye,will alter density and function of conjunctival goblet cells.Therefore,ophthalmologists should be concerned about the biological behavior of conjunctival goblet cells and the relationship between them and ocular surface diseases.
5.Anatomic measurements of internal fixation-related implantation points of inferior thoracic spinal latero-anterior vertebral screws
Chinese Journal of Tissue Engineering Research 2015;19(17):2683-2687
BACKGROUND: There are many reports on the entrance point of adult inferior thoracic spinal latero-anterior screw.Because of the differences in race,districts and the shape of vertebral body are various,and the choice of screw placement position is also varied.OBJECTIVE:To provide an anatomical reference for the implantation of clinical screws for inferior thoracic spinal latero-anterior fixation with the concave rib set as a reference.METHODS:Spinal specimens from 20 adult cadavers were observed,and anatomical data were colected from the concave ribs.One vernier caliper was used for the measurements.RESULTS AND CONCLUSION:The thoracic transverse diameters and the distance between the upper and the inferior edge of the concave rib and upper endplate increased gradualy as the vertebral number increased,whereas the distances between the upper and the inferior edge of the concave rib and inferior endplate and between the anterior edge of the concave rib and anterior edge of the vertebral canal decreased gradualy.Above findings suggested that the anatomical positions of the inferior thoracic concave ribs folowed a set of rules.The concave rib could be used as a simple,constant,and reliable reference point for inferior thoracic spinal latero-anterior fixation screw placement.
6.The diagnostic value of ultrasound for the residual gallbladder
Chinese Journal of Primary Medicine and Pharmacy 2012;19(17):2600-2601,后插1
Objective To explore the diagnostic value of ultrasonography for the residual gallbladder after cholecystectomy.Methods Application of the ultrasound diagnostic apparatus in cholecystectomy patients was to be screened to find the residual gallbladder.Results Ultrasound resuts showed 18 cases of residual gallbladder,which combined stones in 12 cases(66.7% ),polyps in 1 case(5.6% ) ;Atrophic cholecystitis,acute cholecystitis,postoperative residual gallbladder probability were high,accounting for 83.0%.Conclusion Ultrasound for the preoperative prevention and postoperative diagnosis of the residual gallbladder has better value,and the cholecystectomy patients should be routinely review the ultrasound.

Objective To study the anatomical character of compartment syndrome of foot after calcaneal intra-articaular by experimental model. MethodSix intact human cadaver lower extremities were used to produce calcaneal intra-articular fracture models, fracture patterns of the model were observed with radiographical technique, and anatomical study was proceeded to observe the fractures and their effects on soft tissues and compartments in foot.ResultAll specimens were sustained calcaneal intra-articular fractures successfully, 4 were joint depression fracture in x-ray, 2 were tongue type; 3 were Sander Ⅱ type and others were Sander Ⅲ type in CT. the primary fracture line coursed from anterolateral to posteromedial, and from anterosuperior to posteroinferior. It damaged all the soft tissue arosed from fractures medially and laterally, included adductor hallucis,quadratus plantae, flexor digitorum brevis and abductor digiti minimi as well.ConclusionFrom anatomical view, soft tissues of many compartments in foot rather than of simple compartmen are injuried when calcaneal intra-articular fractures occur, decompressive fasciotomies should be performed in all compartments involved. The present experimental protocol is useful to reproduce calcaneal intra-articular fractures.

Objective To investigate the safety and feasibility of lapraroscopic Heller myotomy combined with Dor fundoplication surgery. Methods Three cases with achalasia have been treated with laproroscopic Heller-Dor surgery since February, 2005. Before surgery, patients were examined for generally esophageal barium meal and esophageal manometry. Results The operation time ranged from 110 and 120 minutes with the bleeding volumes between 40 to 50 ml, and the hospitalized time for patients post operation was 6 to 7 days. During a month after surgery, the patients showed the normal lower esophageal sphincter pressure and remnant pressure, increased the rate of relaxation,disappeared reversed peristalsis and gastroesophageal reflux, and no recurred symptoms. Conclusions In comparison to conventional surgery, Heller-Dor procedure results in smaller wound, less pain, fewer complications, faster recovery, shorter hospitalized days, and better therapeutic effectiveness. The Heller-Dor procedure is safe and feasible.
