A method for determinations of germanium in garlic was developed by means of acid digestion and extraction under reflux. It obriated not only the volatile loss of Ge but also the loss of volatile Allicin in the Allium sativum, with usual distillation methods. At the same time the sensitivity was remarkably increased under coprecipitation with ferric hydroxide and extraction operation. A good linear relation was obtained in the range of 0-2.0?g Ge. The average recovery of Ge is 90.9%, coefficient of variation is 4.0%, and detection limit in the Allium sativum is 0.14?g. The method is suitable for determination of Ge in other biological samples as well.

Objective To investigate the risk factors for postoperative cognitive dysfunction (POCD) and nursing intervention in patients undergoing laparoscopic radical hysterectomy. Methods One hundred patients undergoing laparoscopic radical hysterectomy were included, surgical history, general anesthetics way, education, family factors(alone), body mass index, age, duration of anesthesia, dose of sufentanyl, hematocrit, the time for regaining orientation, dysphoria, postoperative pain degree were recorded. The occurrence of POCD was observed at 7 days (early period) and 3 months (later period) after surgery. Logistic regression analysis was used to examine the risk factors for POCD at early period and later period. Results The incidence of POCD at early period was 29.0%(29/100). Logistic regression analysis of surgical history, general anesthetics way, body mass index, age, hematocrit, the time for regaining orientation, postoperative pain degree in patients, general anesthetics way (OR=2.821, 95%CI 1.099-7.240) and postoperative pain degree(OR=2.292, 95%CI 1.129-4.654) were the significant risk factors for POCD at early period. The incidence of POCD at later period was 7.0%(7/100). Logistic regression analysis of education and family factors(alone) in patients, family factors(alone) was the significant risk factor for POCD at later period (OR=5.517, 95%CI 1.010-30.126). Conclusions General anesthetics way and postoperative pain degree are the significant predictors for POCD in patients undergoing laparoscopic radical hysterectomy during hospitalization, and family factors(alone) is the risk factor for POCD at 3 months after surgery, and active nursing intervention could reduce the occurrence of POCD.

Objective:To analysis the impact of public health emergencies on mood fluctuations of depression and the related factors in the elderly in Shanghai, in order to provide a new evidence for early psychological intervention.Methods:A cross-sectional survey was conducted among 983 elderly in the Department of Geriatrics of Xinhua Hospital Affiliated to Shanghai Jiaotong University and two communities in Changning and Hongkou Districts of Shanghai by using a self-compiled social life questionnaire and Geriatric Depression Scale(GDS-30)during corona virus disease(COVID)-19 outbreak from 1 February to 15 February 2020.The mood fluctuations of depression and the related influencing factors were analyzed by comparing the current GDS-30 scores with the scores within previous six months.Results:Of 983 questionnaires, 867 were valid.The incidence of mild fluctuations of depression was increased from 20.9%(181/867)to 27.2%(235/867)during the public health emergencies( P<0.05), with 3 cases of newly emerged severe depression.The GDS-30 scores were higher during the public health emergencies than before the emergencies(9.88±3.85 vs.7.67±3.54, P<0.05). The four risk factors inducing fluctuations of depression in the elderly were the number of coexisted chronic diseases ≥2( P=0.036), the lack of visits or communication from families( P=0.015), the family members exposing a risk to COVID-19( P<0.01), and the daily viewing of epidemic news more than 4 h( P=0.023). Linear regression analysis showed that cough, sore throat, dizziness, sleep disturbance and dyspnea were significantly related to the aggravation of depression(based on the increase of GDS-30 score)( P<0.05). Conclusions:Public health emergencies may exacerbate depression in the elderly.They are more likely to experience the aggravation of depression when they suffer from multiple chronic diseases, lack the child visits or communications, have the family members exposing a risk to COVID-19 and pay excessive attention to the epidemic.

Objective:To establish an early prediction model with multiple indicators to predict the risk of severe acute pancreatitis (SAP) in hyperlipidemic acute pancreatitis (HLAP).Methods:The clinical data of 92 patients with HLAP admitted to the Emergency Department of our hospital from March 2018 to February 2020 were analyzed retrospectively. Among them, 29 cases deteriorated to SAP and 63 cases did not. Univariate analysis was used to screen predictive indicators related to hyperlipidemic severe acute pancreatitis (HL-SAP), and logistic regression analysis was used to screen independent predictive indicators related to HL-SAP. Then a prediction model was established. The area under (AUC) the receiver operating curve (ROC) was used to evaluate the predictive ability of each predictive indicator and the model for HL-SAP. Bootstrap resampling technology was used to validate the predictive ability of the model.Results:Univariate analysis showed that procalcitonin, D-dimer, C-reactive protein, albumin, cholesterol and CT grade had influence on the progression of HLAP to SAP ( P<0.05). Logistic regression analysis showed that D-dimer ( OR=2.112, 95% CI: 1.022-4.366; P<0.05), CT grade ( OR=5.818, 95% CI: 2.481-13.643; P<0.01) and cholesterol ( OR=1.146, 95% CI: 1.004-1.308; P<0.05) were independent risk factor of HL-SAP. The AUC of D-dimer, CT grade, cholesterol and the model were 0.802, 0.875, 0.665 and 0.927, respectively. Internal validation of the predictive ability of the model showed that the C-index was 0.927. Conclusions:In the early phase, application of the prediction model that composes D-dimer, CT grade and cholesterol has a good predictive effect on HL-SAP.

OBJECTIVETo investigate the clinical factors related with liver metastasis from colorectal cancer.
METHODS1 312 colorectal cancer patients treated from 1988 to 1997 were collected to set up the database. Binary and multinomial logistic regression (SPSS 10.0 for windows) and then correlation analysis were used to evaluate the factors concerned.
RESULTSSex, disease course, gross tumor type, differentiation degree, pathological grade, infiltration depth and lymph node metastasis were related with liver metastasis by single factor analysis. Only sex, infiltration depth and lymph node metastasis were related with liver metastasis by multiple factor analysis. More male than female were observed in patients with liver metastasis from colorectal cancer (1.9:1, P = 0.006). Liver metastasis in colorectal cancer was positively related to the infiltration depth into the intestine wall (r = 0.926, P = 0.024). However, the correlation between the distance of lymph node metastasis and liver metastasis in colorectal cancer had no statistical significance (r = 0.748, P = 0.252).
CONCLUSIONSex, depth of infiltration and lymph node metastasis are the main clinical factors related with liver metastasis from colorectal cancer. Male colorectal cancer patients are apt to develop liver metastasis. The deeper the tumor infiltrates, the more the liver metastasis. Age, blood type, symptoms, course, complications, tumor size and site are not related with liver metastasis in colorectal carcinoma.

OBJECTIVETo explore the clinicopathological characteristics, efficacy, and prognostic factors for patients with rectal gastrointestinal stromal tumor(GIST).
METHODSClinicopathological and follow-up data of 61 patients with rectal GIST in our department from January 1990 to October 2012 were analyzed retrospectively and pathology specimens were reviewed. Kaplan-Meier method was used to calculate the survival. Univariate analysis and multivariate analysis were performed to investigate the influencing factors of prognosis with Log-rank test and Cox regression model.
RESULTSThere were 42 male and 19 female patients with a median age of 59 years old. Eighteen cases(29.5%) were confirmed preoperatively as GIST by biopsy and 46 cases were diagnosed as GIST by first pathological examination. Fifteen cases(24.6%) were revised as GIST after re-examination of specimes among whom 14 cases had been diagnosed as leiomyoma or sarcoma, and 1 as neurolemmoma. Tumor location was above peritoneal reflection in 12 cases(19.7%) and below peritoneal reflection in 49(80.3%). Fifty-two patients underwent surgery, including 21 extended resections(lymph nodes clearance and combined organs resection simultaneously) and 31 local resections(tumor rejection or partial resection of rectal wall). Eleven patients received preoperative imatinib(400 mg/d). Forty-one cases received imatinib therapy after operation or biopsy diagnosis, including 25 cases who received palliative treatment for postoperative recurrence. Median follow-up time was 55(6 to 391) months and follow-up longer than 2 years was carried out in 46 patients. Overall survival rates of 1-, 2-, 3- , 5-year were 98%, 95.6%, 86.0% and 73.7% respectively. There were no significant differences between local resection group(96.4%, 92%, 83.3% and 77.3%) and extended resection group (100%, 94.7%, 89.50% and 82.6%)(χ(2)=0.004, P=0.947). Univariate analysis showed that survival was only associated with recurrence and metastasis (χ(2)=4.292, P=0.038). Multivariate Cox analysis showed postoperative survival was not associated with any factors(all P>0.05). The 3-year survival rate of patients with postoperative recurrence or metastasis receiving imatinib therapy was better as compared to those who did not received imatinib(82.7% vs. 71.4%).
CONCLUSIONSRectal GIST are more common in the lower rectum. Surgery is the main treatment for rectal GIST. Local complete resection is the mainstay treatment. Extensive resection and lymph node clearance may not improve survival. Imatinib can improve the prognosis of patients with recurrence or metastasis.
