Objective:To investigate depression of elderly patients in general hospital Method:315 patients aged 60 or above in Tongji hospital were screened with CES-D (Chinese version of Center of Epidemiological Survey-Depression) Results:70 of them (22%) definitely had depression, 53 were suspected of depression Female had higher scores in CES-D than male The less educated had higher score in CES-D Multiple regression showed poor education as a risk factor for depression in elderly patients Discussion: Routine screening for depression in elderly patients in general hospital is necessary

Bone marrow cells and cultures of embryo skin and lung cells from DBA/2 mice were obtained for chromosome analysis in our studies. The specimens were banded by Giemsa staining following trysinization, which produced well-scattered and sharply banded mitotic figures ranging from early metaphase to mid-metaphase. Over 435 bands Within the mouse karyotype can be distinguished. Idiogram of G-banding patterns were constructed on the basis of large amount of karyotype analysis. The features of banding patterns of the individual chromosomes are presented and those chromosomes with similar banding patterns are contrasted to avoid possible misidentification.

Objective To explore the effect of selective gut decontamination in regulation of inflammatory reaction compared with rhubarb and glycerine enema for catharsis in patients with systemic inflammatory response syndrome ( SIRS ), and to discuss its mechanisms. Methods A prospective randomized controlled trial was conducted. Fifty-seven patients with SIRS admitted to Department of General Surgery of Aviation General Hospital from June 2009 to June 2014 were enrolled. The patients were randomly divided into rhubarb decontaminate group, traditional decontaminate group and blank control group, with 19 cases in each group. Besides the treatment for primary disease, including anti-infection, operation, alleviate pain, nutritional support, and maintaining water and electrolyte balance, the patients in rhubarb decontaminate group received aqueous extract from rhubarb 15-20 g by gastric tube, enema, or peros, twice a day;and those in traditional decontaminate group received glycerine enema or glycerol enema, twice a day; while no gavage or enema was prescribed in blank control group. Peripheral blood was collected before and 72 hours after treatment. Enzyme linked immunosorbent assay ( ELISA ) was used to determine the concentration of lipopolysaccharide ( LPS ) and inflammatory mediators. Results Compared with blank control group and traditional decontaminate group, the levels of interleukins ( IL-1, IL-8 ), LPS, platelet activating factor ( PAF ), tumor necrosis factor-α( TNF-α), andγ-interferon ( IFN-γ) before treatment was similar to that of rhubarb decontaminate group [ IL-1 ( ng/L ): 53.154±5.783, 50.564±5.771, 51.082±6.403, F = 0.994, P = 0.377; IL-8 ( ng/L ): 70.492±6.146, 68.376±6.112, 68.673±8.384, F=0.514, P=0.601;LPS (μg/L ):11.630±2.449, 10.858±2.307, 10.463±2.145, F = 1.261, P = 0.291; PAF (μg/L ): 4.173±0.395, 4.051±0.362, 4.078±0.487, F = 0.446, P = 0.642; TNF-α( ng/L ):132.498±10.772, 129.735±12.881, 127.207±11.514, F=0.963, P=0.388;IFN-γ(μg/L ):45.645±4.558, 43.692±5.578, 43.767±5.028, F = 0.904, P = 0.411 ]. The above parameters after treatment were significantly lower than those before treatment in three groups. The effect on the LPS and pro-inflammatory factors of the rhubarb decontaminate group was more obvious than that of the blank control group and traditional decontaminate group [ LPS (μg/L ): 7.571±1.113 vs. 9.008±1.904, 8.874±1.808, F = 4.416, P = 0.017; IL-1 ( ng/L ): 45.309±3.563 vs. 48.731±4.466, 46.112±4.322, F = 3.557, P = 0.035; IL-8 ( ng/L ): 60.492±5.346 vs. 65.553±5.384, 63.437±5.462, F = 4.213, P = 0.020; PAF (μg/L ): 3.519±0.250 vs. 3.832±0.356, 3.766±0.309, F = 5.450, P = 0.007; TNF-α ( ng/L ): 114.988±8.772 vs. 123.230±10.433, 118.534±9.519, F = 3.525, P = 0.036; IFN-γ(μg/L ):38.683±3.190 vs. 41.831±4.122, 39.161±3.972, F=3.820, P=0.028 ]. Conclusion The usage of selective gut decontamination can inhibit the release of endotoxin and inflammatory mediators in patients with SIRS, and it will get a better effect using rhubarb, and the mechanism may be related to the protection of intestinal mucosal barrier function.

CONCLUSION: The method is reliable,accurate and can be used for quality control of Radix Pseudostellariae.

Objective To study the level of immunoglobulin and the prevalence of ANA in patients with Graves' diseases(GD).To explore the correlation between GD and other systemic autoimmune disorders.Methods Data of 145 patients with GD and 45 healthy subjects were collected.All cases were detected on the presence of ANA and the level of immunoglobulin,FT3,FT4,and thyroid specific antibodies.Results The presencerate of ANA and the level of IgG in patients with GD were higher than that in healthy controls [(28.28% vs 4.55%);(70.96?26.14 vs 60.41?11.01) mmol/L](P

ObjectiveTo observe the efficacy and safety of patient-controlled intravenous analgesia (PCIA) with morphine and fentanyl after cardiac surgery.MethodsSeventy patients operated with cardiac surgery were randomly divided into morphine group (group M) and fentanyl group (group F). The beginning efficacy time of analgesia,efficacy of analgesia,patient's evaluation,heart rate,respiratory rate,mean arterial pressure,and incidence of nausea and vomiting were assessed.ResultsThere were no significant differences in efficacy and patient's evaluation between two groups. In group G,the beginning efficacy time of analgesia was significantly shorter than those in group M (P<0.05),and the times of nausea and vomiting were significant less than those in group M (P<0.05).ConclusionPCIA with fentanyl and morphine for postoperative pain relief after cardiac surgery is efficient and safe. Compared with morphine,the beginning efficacy time of fentanyl is significant shorter,and times of nausea and vomiting are little.

Objective: To evaluate the feasibility of hypofractionated intensity-modulated radiation therapy (IMRT) combined with concurrent chemotherapy in patients with locally advanced squamous cell carcinoma of the hypopharynx. Methods:Patients with stageⅢ-ⅣA carcinoma of the hypopharynx were treated with IMRT and cisplatin-based concurrent chemotherapy. Two groups were di-vided according to the prescription dose to the primary gross tumor volume, as follows:Cohort-1 comprised patients who were recruit-ed before February 2013 (70 Gy/33 F and 2.12 Gy/F);and Cohort-2 comprised patients who were recruited since February 2013 (69 Gy/30 F and 2.30 Gy/F). Acute toxicities were evaluated. This study was registered with the number ChiCTR-ONRC-14004240. Results:Between August 2008 and December 2014, a total of 76 patients (35 in Cohort-1 and 41 in Cohort-2) were recruited. No xerostomia of grade 3 and higher was observed in all patients, who showed low incidences of grade 3 skin reaction, oral mucositis, and dysphagia. All patients did not show acute toxicities of higher than grade 4. No statistical differences in acute toxicities were observed between the two cohorts. No statistical difference was observed in acute toxicities between the IMRT techniques. Induction chemotherapy was the inde-pendent prognostic factor for grade 2 xerostomia (P=0.002). Conclusion:The 69 Gy/30 F hypofractionated IMRT was safe and effec-tive in the treatment of locally advanced squamous cell carcinoma of the hypopharynx. Late toxicities and long-term outcome need to be investigated further.

Objective To analyze the complications after procedure for prolapse and hemorrhoids (PPH) in treating severe mucocutaneous hemorrhoids.Methods The clinical data of 550 patients with severe mucocutaneous hemorrhoids who were admitted to the Hangzhou Hospital of Nanjing Medical University from January 2005 to December 2013 were retrospectively analyzed.All the patients were treated by PPH or PPH + external hemorrhoids resection.The postoperative complications were recorded and assessed.Patients were followed up via outpatient examination and telephone interview till June 2014.Results Operation was successfully carried out on all the 550 patients.The operation time and duration of hospital stay were (15 ± 10)minutes and (4.2 ± 1.8)days,respectively.A total of 445 patients were followed up for 6-60 months,with the median time of 28 months.The overall incidence of complications was 14.61％ (65/445).Forty-five patients were complicated with anal pain,12 with hemorrhoid recurrence,7 with bleeding,5 with dysporia,4 with anastomotic stenosis and 2 with rectal and perianal infection.Of the 12 patients with hemorrhoids recurrence,5 was alleviated by medication and 7 received PPH for the second time.Of the 4 patients with anastomotic stricture,the condition of 2 patients were alleviated by anus dilatation,and the condition of 1 patient was alleviated by balloon dilatation under enteroscope,1 patient received circular incision of the stricture because of severe stricture and failed of conservative treatment.Of the 2 patients with rectal and perianal infection,1 was alleviated by intravenous and local medication,and the other patient who was complicated with anal fistula was alleviated by surgery.The condition of other patients was improved after symptomatic treatment.Conclusions PPH is effective and safe for the treatment of severe mucocutaneous hemorrhoids.The main complication is anal pain,and it could be cured or alleviated by symptomatic treatment.

Objective To explore CT features of thin-wall cavity change of pulmonary metastases from renal clear cell carcinoma after molecular targeted treatment and its clinical significance.Methods Clinical and imaging data of 2 patients with thin-wall cavity of pulmonary metastases originating from renal clear cell carcinoma after molecular targeted drug Pazopanib were reported and analyzed retrospectively.Results After resection of primary renal tumors,multiple solid metastatic lesions in the lung were detected and the lesions showed ring enhancement on the post-contrast images.After 3-month Pazopanib treatment,most of the lesions presented thin-wall cavity change.Case 1 showed slowly disease progression while case 2 suffered from spontaneous pneumothorax and died 2 months later.Conclusion Necrosis of pulmonary metastases originated from renal carcinoma can be impelled by molecular targeted Pazopanib treatment,which helped to the formation of cystic thin-wall cavity,but the influence on the prognosis still remains uncertain.
