Objective To investigate the medical cost of 72 patients with panic disorder and efficacy of paroxetine(SSRIs)in the treatment.Methods The course,medical cost,types and times of main examination of all 72 patients were reviewed and analyzed.The effect of paroxetine on the patients was studied in terms of anxiety and depression scale.Results The 72 patients had long course,high medical cost and received many unnecessary medical examinations.Paroxerine was effective on patients with panic disorder in light of anxiety and depression scale.Con- clusion Patients with panic disorder had long course and spent much unnecessany money before final diagnosis. Paroxetine was useful and safe in the treatment of panic disorder.

AIM: To study the effect of ERK inhibition on the mitochondrial potential change in dexamethasone (DEX)-induced thymocyte apoptosis. METHODS: ERK activity was inhibited by PD098059 (PD), and 4 experimental groups were set: control, PD only, DEX and PD+DEX. Annexin V-FITC/PI double staining flowcytometry was used to detect apoptotic cells at time points of 3 h, 5 h and 7 h. JC-1 staining flowcytometry was adopted to examine mitochondrial membrane potential (△?m) at time points of 3 h, 7 h and 11 h. RESULTS: By stimulation with 1 ?mol/L DEX, the apoptotic rates of mouse thymocytes at 3 h, 5 h and 7 h were (19.63?0.35)%, (41.84?1.67)% and (67.00?2.43)%, respectively, and had significantly difference from control group (4.98?0.39)%, (6.08?0.33)% and (9.31?0.34)% (P0.05). At 3 h, 7 h and 11 h, the rates of low △?m cells were (21.23?1.43)%, (55.34?1.78)% and (70.88?2.87)%, significantly higher than that in control group (P0.05). CONCLUSION: DEX induces mouse thymocyte apoptosis at least partly through ERK pathway, and ERK inhibition has an important biological significance during this process.

AIM: To study the changes of mitochondrial membrane potential(△?m) and mitochondrial mass in apoptosis of Jurkat cells induced by camptothecin(CPT).METHODS: Jurkat cells were treated with CPT.Annexin V-FITC/propidium iodine(PI) double stainig was used to detected early stage of apoptosis and PI staining for analyzing the cell cycle.Jurkat cells were stained by annexin V-PE/DiOC_6(3) to detect changes of △?m.The mitochondrial mass was measured by cytometry with NAO staining.RESULTS: 6 h after treated with 10 ?mol/L CPT,the rate of early apoptotic cells(22.59?1.04)% had significantly difference compared with control group(3.93?0.73)%(P0.05).Apoptotic peak appeared obviously after treated with CPT,the percentage of late apoptotic cells(13.58?0.97)% had distinctly difference compared with control group(3.18?0.51)%(P

0.05) compared with control group at 1 h and 3 h; while ~FL 1 in DEX group at 5 h (660.91?72.95) was significant lower (P

Objective To investigate the efficacy of transcatheter closure of coronary artery fistula (CAF) by transthoracic echocardiography(TTE) and the role of TTE in this therapy. Methods CAF were occluded with transcatheter closure techniques in 17 patients. TTE was performed before and after the treatments. The key points were retrospectively analyzed including: the sites of CAF, the position and diameter of CAF,the shape and position of the devices after the intervention,the residual shunt,and cardiac chamber size. Results Before the therapy,TTE made definite diagnosis of CAF. All patients had lesions in single coronary artery, and the diameter of CAF was 2-14 (6.4 ± 3.5)mm. All patients underwent transcatheter closure successfully. TTE revealed the shunts disappear 1-4 days after the occlusion. During a follow-up period of 1- 29 (11.7± 7.9)months,no residual shunts, no complications, and normal size of thecardiac chambers were recognized by TTE. Conclusions The transcatheter closure of CAF has emerged as a less invasive, safe and effective strategy. Echocardiography has important role in primary screening of patients and the follow-up after the treatments.

Objective To detect the levels of cytokine IL-2,IL-12,IFN-?and IL-4 secreted by peripheral CD8~+ T lymphocytes in patients with condyloma acuminatum (CA).Methods Flow cytometry was employed to study the expression of cytokines IL-2,-12,INF-?and IL-4 in CD8~+ T lymphocytes in the peripheral blood of 60 patients with CA and 20 healthy controls.Results The percentage of CD8~+ T lym- phocytes producing IL-2,IL-12 and IFN-?were significantly lower in CA patients than that in healthy con- trols (P

Objective To study P300 of the first episode depression and mismatch negativity(MMN) changes after antidepressant treatment. Methods Sixty-four patients with first episode depression were evaluated by HAMD 17, and P300 and MMN tests were performed at the baseline and week 12. The cognitive potentials were compared with those of control group(N=36). Results Compared with the control group, depressive patients had longer latency of P300 and MMN,lower amplitude of P300 and MMN before treatment (P

Objective To analyze the diagnosis and treatment for complications of renal caliceal diverticulum with calculi or infection. Methods A retrospective investigation was performed on 29 cases with renal caliceal diverticulum. The 29 cases included 11 males and 18 females aged 18 to 61 years. Among the study group, 3 cases were simple renal caliceal diverticulum, 12 cases were diagnosed as diverticular calculi and 14 cases presented recurrent urinary tract infections including 3 cases with urinary fistula after unroofing and decompression as renal simple cyst from another hospital. Ten cases underwent an open operation that unroofed and decompressed the cyst, and sutured the diverticular neck. Eight cases underwent laparoscopic operation similar to the open operation, including lithotomy in caliceal diverticulum in 2 cases. Eleven cases diagnosed with caliceal diverticular calculi were taken one-stage percutaneous nephrolithotomy including dilating the diverticular neck, remaining the nephrostomy catheter and Double-J ureteral stents, and 1 case was transferred to open operation.Results The open and laparoscopic operations were performed successfully. One case was cured by Double-J ureteral stenting after postoperative urinary leakage. One case was transferred to open operation for the failure of percutaneous puncturation. X-ray examination revealed that there were no remaining stones after the operation. All the patients were followed up for 6 to 24 months without calculi and infection recurrence. Conclusions Stones and infection are common that complications of renal caliceal diverticulum. Percutaneous nephrolithotomy, laparoscopy and other operations were effective and feasible treatment options for cases with complications of renal caliceal diverticulum. Exact diagnosis was very important for treatment of renal caliceal diverticulum before operation.

OBJECTIVETo study the effect of aqueous extracts of Polygonum multiflorum (AEPM) on bile acid synthesis, metabolism and transfer-related molecules in rat liver and the hepatotoxicity-related mechanism of P. multiflorum.

METHODSprague-Dawley rats were orally administered with 30, 60 g x kg(-1) APEM once everyday for consecutively 28 days. At the end of the experiment, mRNA and protein expressions of hepatic MRP3, MRP2, BSEP, FXR and CYP7A1 were detected by Real-time PCR and Western blot

RESULTCompared with the normal group, the AEPM high dose group showed significant increases in mRNA expressions of hepatic MRP3 and BSEP of male rats (P < 0.05); AEPM high and low dose groups revealed a notable decrease in mRNA expressions of hepatic FXR (P < 0.05) and remarkable rises in mRNA expressions of hepatic MRP3, MRP2, BSEP, CYP7A1 among female rats (P < 0.05). According to the test results of western blot assay, AEPM high and low dose groups showed consistent changes in protein and mRNA expressions hepatic MRP3, MRP2, BSEP, FXR, CYP7A1.

CONCLUSIONThe 28 oral administration with AEPM in rats showed a certain effect on expressions of bile acid synthesis, metabolism and transfer-related proteins, as well as cholestatic or choleretic effects in the mRNA expression.
