OBJECTIVETo compare the efficacy difference in the treatment of senile insomnia among western, medication, acupuncture and the integrated therapy of acupuncture and western medication.

METHODSNinety-eight patients of senile insomnia were randomized into a western medication group (30 cases), an acupuncture group (35 cases) and an integrated acupuncture and medication group (35 cases). In the western medication group, estazolam 1mg was prescribed, taken 30 min before going to bed, oryzanol 20 mg, oral administration, three times a day, for 4 weeks totally. In the acupuncture group, the simple acupuncture therapy was applied at Shenmen (HT 7), Sanyinjiao (SP 6), Anmian (Extra), Baihui (GV 20) and Sishencong (EX-HN 1), as well as the supplementary points selected according to the differentiation. The acupuncture treatment was given once a day, 5 treatments a week, for 4 weeks totally. In the integrated acupuncture and medication group, the western medication was combined with acupuncture. The dosage and usage of western medication were same as those in the western medication group; and acupoints in acupuncture treatment were same as those in the acupuncture group. The treatment lasted for 4 weeks in the three groups. Pittsburgh sleep quality index (PSQI) and clinical efficacy were observed before treatment, after 4 weeks' treatment and in 4 weeks after discontinuity of treatment in the three groups.

RESULTSFour weeks after treatment, the clinical curative rates were 3. 3% (1/30), 21. 2% (7/33) and 25. 7% (9/35) in the western medication group, the acupuncture group and the integrated acupuncture and medicines group separately. The total effective rates were 70. 0%(21/30), 93. 9%(31/33) and 97. 1%(34/35) in the three groups separately. The curative rates and the total effective rates in the integrated acupuncture and medication group and the acupuncture group were higher than those in the western medication group separately (all, P<0. 01). PSQI scores after 4 Weeks' treatment were all improved as compared with those before treatment in the three groups (all P<0. 05). PSQI score in either the integrated acupuncture and medication group or the acupuncture group was lower than that in the western medication group, indicating the significant difference (both P< 0. 05). Four weeks after discontinuity of treatment, the efficacy was stable in the acupuncture group and the integrated acupuncture and medication group. PSQI score did not change as compared with that in the 4th week of treatment. The score in the western medication group ran back, close to that before treatment (P>0. 05). During the treatment, a few patients had dry mouth in the western medication group. The adverse reactions were not discovered in the other two groups.

CONCLUSIONThe integrated therapy of acupuncture and medication achieves the quick efficacy on senile insomnia and rapidly relieves the symptoms, with quite high clinical curative rate and total effective rate obtained. The long-term efficacy is better than that of western medication. The integrated therapy is the first option among the three therapeutic programs.

Background and purpose:Early evaluating the therapeutic efficacy of transcatheter arterial chemoembolization (TACE) in patients with hepatic cancer is still a diffcult clinical problem. The purpose of this study was to evaluate the ability of the apparent diffusion coeffcient (ADC) to help predict early disease progression after TACE.Methods:Institutional review board approval was obtained, and all patients signed informed consent. Magnetic resonance imaging (MRI) and diffusion-weighted imaging (DWI) (b=50, 500, 1 000 mm2/s) were performed before and 1 month after initiating TACE for 23 patients with hepatic cancer (14 were male, 9 were female; mean age: 53.3 years;range: 21-85 years). Contrast-enhanced MRI was performed 3 months after initiating TACE. Patients were classiifed as either progressing or non-progressing according to RECIST 1.1. The preoperative ADC values of tumor and the ADC values of tumor 1 month after TACE were analyzed by pairedt-test in both progressing and non-progressing group. Unpairedt-test was used to compare ADC parameters between progressing and non-progressing group. In all the 23 hepatic cancer patients, receiver operating characteristic (ROC) curve analysis was performed to determine a threshold ADC ratio (ADC%) to differentiate progressing from non-progressing patients.Results:Thirteen progressing and 9 non-progressing patients were evaluated. Increase in ADCs of tumor was observed in non-progressing patients at 1 month after TACE compared with preoperative ADCs. There was a signiifcant difference between the 2 groups (P=0.01). In progressing group, preoperative ADCs of tumor were similar to those at 1 month after TACE (P=0.221). There was no significant difference in preoperative ADCs of tumor and ADC% between the progressing and non-progressing groups. In patients with hepatic cancer, 1 month ADC ratio in non-progressing patients were signiifcantly higher than those of progressing patients (P=0.029). Using ROC to evaluate the ability of ADC% could predict early disease pro-gression after TACE. Using -6.455% as the threshold, the area under the ROC curve was 0.867 (95%CI: 0.643-1.000). The sensitivity was 100%, and the speciifcity was 66.7%.Conclusion:One month after TACE, the increases in ADCs of tumor were observed only in the non-progressing group; and the ADC ratio seems to be a promising tool for helping predict the early disease progression after TACE in patients with hepatic cancer.

Background and purpose: With characteristic but non-specific features, subsolid pulmonary nodules (SSPN) is closely associated with early lung cancer. This study aimed to estimate the imaging value of SSPN in stageⅠA lung cancer, and summarized the radiological features of various SSPNs, retrospectively. Methods:The clinical data and imaging data of 405 patients with solitary pulmonary nodules (SPNs) from Apr. 2008 to Apr. 2014 at Fudan University Shanghai Cancer Center were collected. According to ground-glass opacity (GGO) proportion, SPNs were divided into 3 groups:pure ground-glass opacity (pGGO), mixed ground-glass opacity (mGGO) and solid nodule (SN). The malignant ratios were calculated based on the postoperatively pathological results. Besides, SSPNs were classiifed into stageⅠA lung cancer group and benign lesions group aiming at identifying the differentiating computed tomography (CT) features. Results:Of the enrolled 405 SPN patients, there were 367 SSPNs (including 124 pGGOs and 243 mGGOs) whose incidence in stageⅠA lung cancer group was signiifcantly higher than those in benign group [95.9%(257/268) vs 80.3%(110/137), P<0.001]. The total malignant ratio of SSPN was 70.0%(257/367), mGGO had a higher malignant ratio (72.0%) than those of pGGO (66.1%) and SN (28.9%). The malignant SSPNs were frequently detected in upper lobe of middle-aged women with a higher incidence of irregular edge, spiculation, lobulation and pleural retraction than benign group (P<0.05). Conclusion:SSPN is one of the signiifcantly malignant indicators, and mGGO has the highest malignant tendency. Senility, female, irregular edge, spiculation, lobulation, pleural retraction and pulmonary upper lobe distribution are demonstrated the signiifcant discriminators from benign lesions.

Through the experiments of producing spherical steel-bullet (4.763mm in caliber and 0,44gm in weight) wound on the hind legs of 17 dogs, the authors re- ported that there was a definite linear relationship between the reactions of the serum creatine kinase and the amount of kintic energy from the high speed of the bullets absorbed by the tissues and also with the weight of dead tissue removed around the bullet-path, Within the first 6 hours after injury, the activity of SCK increased with the rise of the biologic effect values of the amount of the kinetic energy absorbed and the weight of the dead tissue removed.

measured to compare the correlation between the changes of T lymphocyte subsets before and after operation and the change of platelet. Results Thirty-one patients were underwent laparoscopic splenectomy. The T lymphocyte subsets and CD3 + ,CD4 + and CD3 + / CD4 + in all patients showed an increase trend as the time prolonged after operation,and the differences were significant( F = 6. 91,3. 93,4. 18;P = 0. 023,0. 004,0. 011). While the ratio of CD3 + / CD8 + and CD3 + CD4 + / CD3 + CD8 + were decreased as time increased,and differences were statistically significant( F = 2. 59,3. 67;P = 0. 001,0. 002). They were related with platelet change after operation and correlation statistics analysis showed R values were 0. 332,0. 271,0. 345,- 0. 119,- 0. 164,and the P value were 0. 039,0. 021,0. 002,0. 017,0. 023. Conclusion ITP patients have the imbalance of T lymphocyte subsets,and splenectomy can improve the imbalance of T lymphocyte subsets in patients with ITP. T lymphocyte subsets may serve as a reference index to indicate the prognosis of the patients.

Objective To investigate the expression and significance of super oxide dismutase activity and malondialdehyde concentration in the serum and adrenal grands of patients with adrenocortica diseases. Methods 12 patients with adrenal hyperplasia and 10 patients with adrenal adenoma which were carried out hospital surgery and confirmed by pathology, and 11 cases of normal as controls were selected.The serum level of Cu/Zn-SOD, Mn-SOD and MDA before operation, and Cu/Zn-SOD and Mn-SOD positive cells percentage of adrenal tissue were compared between three groups. Results Before adrenalectomy SOD activity was lower(P <0.05)and MDA concentration was higher in serum(P<0.05)than the control group.Cu/Zn-SOD positive cell was lower in adrenocortical adenoma tissue than that of adrenocorticohyperplasia and normal cortex(P <0.05).Mn-SOD positive cell had a significant difference among adrenocortical hyperplasia, adrenocortical adenoma and normal adrenal cortex tissue(P <0.05).Both SOD positive cell in adrenocortical adenoma tissue were the lowest of all.In addition,the expression of SOD in tissue had a significant positive correlation with serological expression in study group. Conclusion The superoxide dismutase activities and malondialdehyde concentration seemed to change with adrenocortica diseases.The detection of superoxide dismutase activities and malondialdehyde concentration in the serum and adrenal grands could be the potential methods for the diagnosis and differential diagnosis of adrenocortica diseases.

Objective To evaluate the efficacy and safety of transurethral thulium-Yag laser(Tm-Yag Laser) resection of bladder tumor in the treatment of non-muscle invasive bladder cancer(NMIBC).Methods The clinical data of 186 patients who underwent transurethral resection with pathologically identified of NMIBC were retrospectively analyzed.76 cases and 110 cases were in the transurethral resection of bladder cancer Tm-Yag Laser group and TURBT group,respectively.The operative time,intraoperative blood loss,incidence of obturator nerve reflex,days for urethral catheterization,duration of hospitalization after surgery,detection rate of muscle layer in postoperative pathologic examination and recurrence between the two groups were compared.All patients were followed up for 24 months.Regularly gemcitabine intravesical instillation chemotherapy and cystoscopy were performed postoperation.Results The operative time [(27.08±5.56) min vs.(25.55±5.37) min,P>0.05]and intraoperative blood loss [(14.23±4.05) mL vs.(15.10±3.24) mL,P>0.05]showed no differences between the two groups.The incidence of obturator nerve reflex in Tm-Yag laser group was lower than that in TURBT group (0.0% vs.5.5 %,x2=4.28,P=0.038).The days for urethral catheterization [(3.48±1.05) d vs.(4.02±1.14) d,t=3.328,P=0.001]and the duration of hospitalization after surgery [(4.47±1.08) d vs.(5.02±1.13) d,t=3.350,P=0.001]in Tm-Yag laser group were significantly shorter than those in TURBT group.In Tm-Yag laser group,the detection rate of muscle layer in postoperative pathologic examination was higher than that in TURBT group(x2=14.96,P=0.001).The total rate of tumor recurrence in Tm-Yag laser group was significantly lower than that in TURBT group(13.2 % vs.25.5%,x2=4.18,P=0.041).Conclusion Transurethral Tm-Yag laser is safe and effective in the treatment of NMIBC.It can avoid the incidence of complications and reduce tumor recurrence rate,which is worthy of promotion.

Background and purpose: Current colorectal cancer patient-derived xenografts (PDXs) models were established by samples taken during surgery. However, metastatic colorectal cancer (mCRC) patients have less surgical opportunities, and it was difcult to obtain enough tumor fragment. The aim of the present study was to es-tablish mCRC PDXs by image-guided biopsy. Methods: A total of 12 patients with colorectal cancer who underwent surgery were included. All patients had recurrent lesions or metastatic lesions needed to be histologically confirmed, and none of them had contraindication to biopsy. Tumor tissues not required for clinical diagnosis were used to establish mCRC PDXs. Results: Seven PDXs grew sufficiently for transfer into mice. The success rate was 77.8%. Conclusion:The PDXs established by image-guided biopsy had the advantage of convenient operation, good reproducibility, high achievement ratio, short experimental periodicity and reliably retain specific genetic and morphological features of the primary patient tumors.
