Objective To explore the prevalence of depressive symptoms in postoperative patients with ovarian cancer and to analyze its influencing factors from multiple dimensions, including clinical characteristics, psychological factors, and laboratory indicators. Methods A cross-sectional study was conducted, which enrolled 235 postoperative patients with ovarian cancer. Depressive status was assessed using the patient health questionnaire, and the demographic, pathological, and medical record data of the patients were collected using the generalized anxiety disorder scale, Pittsburgh sleep quality index, European organization for research and treatment of cancer quality of life questionnaire core 30, and ECOG performance status score. Peripheral blood tumor marker (CA125), routine blood test, lymphocyte subsets, and serum cytokine levels were measured. Univariate and multivariate binary logistic regression analysis were used for statistical analysis. Results The prevalence of depression in postoperative patients with ovarian cancer was 39.15% (92/235). Univariate analysis showed that ECOG score ≥ 2 points, pain, anxiety, poor sleep quality, low quality of life, low life satisfaction, tumor recurrence, six or more cycles of chemotherapy, as well as higher levels of CA125, NLR, and NAR, and lower hemoglobin levels were significantly associated with depression (all P<0.05). Multivariate binary Logistic regression analysis showed that anxiety (OR=1.975, 95%CI: 1.231-3.170), sleep efficiency (OR=4.181, 95%CI: 1.211-14.43), sleep latency (OR=34.806, 95%CI: 4.258-284.542), ECOG performance status score, cognitive function (OR=0.918, 95%CI: 0.868-0.97), and life satisfaction were independent risk factors for depression (all P<0.05). Laboratory indicators were not independent influencing factors in the multivariate Logistic regression model. Conclusion Depression in postoperative patients with ovarian cancer is influenced by physiological, psychological, and social factors. Clinical management should focus on patients with anxiety, sleep disorders, poor physical condition, and low life satisfaction, and a comprehensive prevention and treatment strategy centered on psychological intervention and taking into account symptom management and social support should be implemented.

Objective To explore and identify the nutritional/inflammatory indicator with the highest predictive potential for overall survival(OS)in postoperative tumor patients so as to provide guidance for postoperative rehabilitation of tumor patients.Methods Data from 3 191 surgical patients were collected,including 15 nutritional/inflammatory indicators.The maximum selection rank statistic method was used to calculate the optimal cut-off values for continuous indicators.The Kaplan-Meier method was used to assess OS,and Cox proportional hazards models were used to analyze the association between the aforementioned 15 indicators and survival.The predictive value of these 15 indicators was evaluated with receiver operating characteristic(ROC)curves and C-index.Results Multivariate analysis showed that all 15 indicators were significantly associated with poorer OS in surgical patients(P＜0.05 for all).Time-dependent area under the curve(AUC)and C-index analysis indicated that 3 indicators with the highest predictive potential in OS in postoperative tumor patients were the nutritional risk index(NRI)(C-index:0.597),C-reactive protein-to-albumin ratio(CAR)(C-index:0.587),and C-reactive protein-to-lymphocyte ratio(CLR)(C-index:0.587).The optimal cut-off value for NRI was determined to be 104.31(i.e.,NRI＜104.31 suggests malnutrition)with the maximum selection rank statistic method,the optimal cut-off value for CAR to be 0.05(i.e.,CAR≥0.05 suggests a strong inflammatory response,often accompanied by malnutrition),and the optimal cut-off value for CLR to be 1.18(i.e.,CLR≥1.18 suggests a strong inflammatory response).Subgroup analysis indicated that NRI,CAR,and CLR had good correlation with tumor staging,and there were significant differences between tumor node metastasis(TNM)Ⅲ/Ⅳ stage patients and TNM Ⅰ/Ⅱ stage patients when there was a strong inflammatory response or malnutrition.Conclusion In postoperative tumor patients,NRI,CLR,and CAR have high prognostic value.Combining these with the patient's clinical stage,it enables more precise guidance for clinical diagnosis and treatment strategies.

The pathophysiological process of immune inflammatory response after severe trauma is extremely complex, especially manifested in the dynamic changes. In the physiological response state, the inflammatory and anti-inflammatory conditions are in a dynamic balance. The immune inflammatory response is relatively stable, avoiding excessive inflammatory reactions or immunosuppression and reducing further damage to the body. In the pathological response state, the dynamic balance between inflammatory and anti-inflammatory is broken, and it can also lead to persistent inflammatory-immunosuppression-catabolism syndrome (PICS). As a result, it increases serious complications such as uncontrolled inflammatory reactions, sepsis, multiple organ dysfunction syndrome (MODS), and multiple organ failure (MOF). Current researches on post-traumatic immune inflammatory response have also expanded to the genetic level, indicating that the over-expression of genes and the generation and increase of immune response media are likely to be the key reasons for the disorder of immune inflammatory response. The author reviews the research progress of immune inflammatory response mechanism and related clinical intervention after severe trauma, in order to summarize the previous research results and explore the future research direction.

Objective To evaluate the feasibility and efficacy of posterior enlargement of spinal canal for the treatment of multi-segmental cervical diseases without cervical lordosis.Methods From January 2013 to June 2017,a retrospective study was conducted with 21 patients of multi-segmental cervical diseases accompanied cervical lordosis loss,and the complete followup data was obtained.There were 14 males and 7 females,with an average age of 53.9±7.3 years (range,42-65 years).There were 14 multi-segmental cervical spondylotic myelopathy,5 ossification of posterior longitudinal ligament,and 2 congenital cervical stenosis included in this study.The cervical lordotic angle and cervical curvature index were measured preoperatively and 1 year postoperatively.To access the enlargement of spinal canal and spinal cord,the anteroposterior diameter and cross section area of spinal canal or spinal cord were measured on MRI preoperatively and 1 year postoperatively.The Japanese Orthopaedic Association Scores (JOA) was applied to evaluate the neurological function at preoperation and postoperation.Visual Analogue Scales (VAS) was applied to evaluate the pain degree at preoperation and postoperation.Frankel classification was used to assess the severity of spinal cord injury at preoperation and postoperation.Results The follow-up time was 12-26 months,with an average of 16.4 months.The cervical lordosis angle was 3.1°±2.3° preoperatively,and 4.2°±1.6° 1 year postoperatively with a significant difference.The cervical curvature index was 4.4％ ± 1.7 ％ preoperatively and 5.0％ ± 1.5 ％ 1 year postoperatively with no statistically difference.Except for C7T1 level,the preoperative anteroposterior diameter and cross section area of spinal canal at C2.3,C3.4,C4.5,C5.6,and C6.7 level were lower than that at 1 year after operation with a significant difference.Except for C2,3 and C7T1 and level,the preoperative anteroposterior diameter and cross section area of spinal cord at C3,4,C4,5,C5,6,and C6,7 level were significantly lower than that at 1 year after operation.The average JOA score preoperatively was 8.9±1.7.The average JOA score at 3 months postoperatively was 13.1±2.0,which was significantly higher than that preoperatively.At 3 months postoperatively,the average improvement rate was 52.0％,and the superior rate was 52.3 ％.At 1 year postoperatively,the average JOA score was 13.3±2.1,which improved significantly from that preoperatively.The average improvement rate was 54.3 ％,and the superior rate was 61.9％.The VAS score at preoperatively was 3.0±2.4,and which was 2.7± 1.7 at 1 year postoperatively with no significant differences.At pre-operation,the level of Frankel classification was C level in one (4.8％) case,D level in 8 (38.1％) cases and E level in 12 (57.1％) cases.At 1 year postoperatively,the level of Frankel classification was C level in one (4.8％) case,D level in 6 (28.6％) cases and E level in 14 (66.7％) cases,compared with that at preoperatively,there was no statistically significant difference.One patients suffered from neurologic deterioration at 1 year after surgery and recovered after anterior cervical surgery.No other serious complications were occurred.Conclusion For the patients with multi-segmental cervical diseases accompanied cervical lordosis loss,effective spinal decompression by cervical posterior laminoplasty was feasible,and a good clinical efficacy was achieved.

Objective To evaluate the effect of pre-emptive analgesia on pain and inflammation control in patients with severe multiple trauma.Methods Severe multiple trauma patients treated in the emergency department from September 2014 to December 2014 were prospectively included based on the inclusion criteria including injury severity score (ISS) of 16 to 25,Glasgow Coma Scale (GCS) ≥ 13 and visual analogue scale (VAS) ≥ 4.The patients were assigned to pre-emptive analgesia group,traditional analgesia group and non-analgesia group,according to the random number table.Pre-emptive analgesia group had patient-controlled intravenous analgesia (PCIA) with sufentanil and tramadol on admission.Traditional analgesia group were administered intramuscular pethidine or subcutaneous morphine for temporary analgesia when the pain could not be tolerated.Non-analgesia group received no analgesia.VAS,systemic inflammatory response syndrome (SIRS) score and serum interleukin (IL)-6 concentration were compared among the groups on admission day,24,48,72,120,168 and 240 h after admission.Results Fifty-seven patients (46 males and 11 females) were included,and age was (39.61 ± 12.05)years.There were 18 patients in pre-emptive analgesia group,20 patients in traditional analgesia group,and 19 patients in non-analgesia group.Comparison between pre-emptive analgesia,traditional analgesia and non-analgesia groups showed no significant differences on admission with respect toVAS [(6.5±1.5),(6.6±1.4),(6.4 ±1.4)points],SIRS [(3.3±0.7),(3.4±0.6),(3.4±0.8) points] and IL-6 concentration [(109.2 ± 47.9),(99.9 ± 44.3),(106.3 ± 50.0) ng/L] (P ＞0.05).Compared to traditional analgesia and non-analgesia groups,VAS and SIRS score in pre-emptive analgesia group differed significantly at 24,48,72,120,168 and 240 h after admission,and IL-6 in pre-emptive analgesia group differed significantly at 48,72,120,168 and 240 h after admission (all P ＜0.05).VAS,SIRS score and IL-6 concentration declined faster in pre-emptive analgesia group than other two groups (P ＜ 0.05),while there were no significant differences between traditional analgesia and nonanalgesia groups (P ＞ 0.05).Positive correlation was noted between VAS and SIRS score,and between VAS and t IL-6 concentration (P ＜ 0.05).Conclusion Pre-analgesia provides quick and effective pain relief and attenuate excessive systemic inflammation response that contributes to stabilization and recovery of the severe multiple trauma patients.

Objective To analyze the related factors of foot blisters caused by long-distance weight-bearing march and to explore the pathogenesis of foot blisters to provide a useful way for the prevention and treatment.Methods After the 300 km march,counted the number who had accomplished the march,and then recorded the number of foot blisters,location of blisters,and abrasion of sole.Collected the data of gender,age,body mass index (BMI),hand dominance,and whether had bliters before the march through questionnaire.And the data were coded for analysis with SPSS 13.0 statistical package.Results The 7 cases who complete the whole march and 17 cases who already had foot blisters before the march were ruled out of the final statistics.Among the remaining 590 cases,there were 554 cases (93.9%)suffered from foot blisters.And there were 1 282 blisters in total,among which the plantar blisters occupied 98% (1 257 cases).The analysis showed that the incidence of foot blisters had no significant correlation with gender,left/right foot,hand dominance,BMI and age.The predilection sites of blisters were the second and third metatarsals (28.2%),the hallux (21.3%),the fifth metatarsal (18.1%),and the calcaneus (15.8%)of the left foot.The predilection sites of blisters were the second and third metatarsals (33.3%),the hallux (22.4%),the fifth metatarsal (18.6%),and the calcaneus (14.5%)of the right foot.In terms of the abrasion of sole,the lateral heel was worn out the most (34.6% on the left and 34.2% on the right).Conclusion The study confirmed that the incidence of foot blisters had no significant correla-tion with gender,left/right foot,hand dominance,BMI and age,which may be affected by the particularity of this march.Most of the foot blisters occurred in the planta,and the predilection sites of blisters were in accord with sites of of the abrasion of sole and the distribution of plantar shear force,which demonstrated the shear force is the most critical factor on the pathogenesis of foot blisters.

Objective To investigate the effect of nutritional counseling combined with oral high-fat, high-protein nutritional supplement (Ensource) on nutritional status and clinical outcomes of esophageal cancer patients under radiotherapy treatment.Methods Totally 80 esophageal cancer patients under radiotherapy treat-ment who were able to take oral feeding and with Nutritional Risk Screening 2002 (NRS 2002) score≥3 were se-lected and divided into a study group (n=41, nutritional counseling combined with oral nutritional supplements) and a control group ( n=39, nutritional counseling) with a random number table.Energy intake, nutritional sta-tus, and incidences of radiotherapy complications of the two groups before and after radiotherapy were compared. Results Energy intakes in the study group increased significantly during radiotherapy compared with the control group [ (2 445 ±686) kJ vs.(1 747 ±456) kJ, P=0.003];and the level of prealbumin and transferrin were increased significantly compared with before radiotherapy [ (17.35 ±5.83) mg/L vs.(20.15 ±6.02) mg/L, P=0.008;(213.74 ±52.66) mg/L vs.(264.19 ±43.78) mg/L, P=0.002].Besides, compared with the control group, incidence of radiation esophagitis ( GradeⅢ) and radiation skin injury ( GradeⅢ) in the study group decreased significantly (24%vs.38%, P=0.000;27%vs.41%, P=0.000).Conclusion Nutritional counseling combined with oral nutritional supplements in esophageal cancer patients could help improve the patients'nutritional profile and decrease the incidence of complications related with radiotherapy.

A molecularly imprinted polymer (MIP) for the selective solid phase extraction of imidacloprid, imidaclothiz, thiacloprid was synthesized by polymerization for 24 h using thiacloprid as template. Dynamic adsorption and selective adsorption test showed that the MIP could quickly adsorb the imidacloprid, imidaclothiz, thiacloprid, with good selectivity for targets. The maximum static adsorption capacity of MIP was 31. 7, 36. 7 and 45. 3 mg / g, respectively. A molecularly imprinted solid phase extraction (MIP-SPE) was developed to separate, clean up and enrich the thiacloprid, imidacloprid and imidaclothiz residue in paddy water, soil, rice, tomato, cucumber. The average recoveries were 80. 2% -98. 8% , with relative standard deviation of 1. 4% -4. 5% . The MIP-SPE was used to analyses the real samples, the result was satisfied.

Objective:To investigate whether the nutrition support team (NST) benefits esophageal carcinoma (EC) patients who are concurrently undergoing chemoradiotherapy. Methods: Between June 2012 and December 2013, 40 EC patients undergoing chemoradiotherapy were divided into the NST group and routine treatment (RT) group, with 20 patients in each group. At the end of chemoradiotherapy, the nutritional status, incidence of complications, and completion rates of radiotherapy were evaluated. The length of hospital stay (LOS) and cost were also compared between the two groups. Results:The nutrition and blood parameter values of the NST group were better (P<0.05) than those of the RT group. The incidence of complications was lower in the NST group (P<0.05) than that in the RT group. In addition, all patients in the NST group achieved the treatment plan, whereas five of the patients in the RT group interrupted or delayed the plan (P<0.05). The average LOS decreased by 3.8 d (P<0.05), and the hospitalization costs were reduced to 6300 RMB person-times (P>0.05) for the patients of the NST group. Conclusion: NST could maintain the nutritional status and improve the treatment compliance and tolerance of EC patients undergoing chemoradiotherapy, thereby shortening the LOS time and reducing the costs.
