Objective:To explore the CT manifestations of intervertebral disc calcification(IDC)in children patients and its di-agnostic value in comparison with plain film.Methods:CT and plain film data of sixteen children with IDC were collected.The images were analyzed from the following aspects:counting the involved discs of each patient,locating the calcification in each ill disc and nearby tissue,observing the morphological features of calcification,and vertebral tube involvement.Results:①Fifteen patients had one or more than one cervical disc involved,but in only one patient,calcification involved five thoracic discs.Twenty-six discs were calcified in all,in which cervical disc accounted for 77%,and thoracic disc 23%.Most calcifications were nodular or patchy with different size.Sixteen calcification located at the anterior half segment of involved discs;Eight in the central part;only two at the posterior part.②CT and plain film detected calcification respectively of 26 and 25 discs.The for-mer was superior in displaying the location and appearance of calcification,and disclosing vertebral tube and nearby tissue in-volvement.Conclusion:CT is better than plain film in disclosing the details of ill disc.

ObjectiveTo investigate the effect of cognitive therapy on the prognosis of the stroke patients with depression.Methods80 stroke patients with depression diagnosed according to Hamilton Depression Scale-17 (HAMD-17) were randomly divided into the treatment group and control group with 40 cases in each group. All patients of two groups were treated with routine therapy, but those of the treatment group were added with the cognitive therapy. All patients were re-evaluated one month and six months later.ResultsAfter treatment, the neurological function of all patients improved, but the scores of HAMD-17 of the patients in the treatment group were significantly lower than that of the control group (P<0.01), and the effect of the treatment group was significantly superior to the control group (P<0.01).ConclusionThe cognitive therapy may improve the prognosis of the stroke patients with depression.

Objective To determine the most appropriate method in the treatment of choledocholithiasis. Methods The clinical data of 135 patients who received either laparoscopic common bile duct exploration (LCBDE) or laparoscopic transcystic common bile duct exploration (TC-BDE) from May 2005 to July 2009 were retrospectively studied. Results All patients were cured of choledocholithiasis. In 13 patients three trocars were used, in 89 patients four trocars were used, and in 33 patients conversion to open operation was done. Of the 102 patients in whom minimal invasive surgery was successfully carried out, TC-BDE was done in 6 patients and LCBDE in 96 patients. Primary closure of common bile duct (CBD) was carried out in 33 patients while T-tube drainage was done in 63 patients. Six patients had a transient bile leak which healed spontaneously in 3 to 4 days. Retained stone was detected in 2 patients which was successfully retrieved through choledochoscopy. Conclusion An individualized treatment approach is the most reasonable way to manage CBD stones. The choice of the procedure depends on the number and size of stones, the surgeons experience and the patient's choice.
