Objective To survey the value of risperidone in the treatment of depression without psychotic symptoms. Methods 205 depressive patients were randomly divided into 3 groups: risperidone group, fluoxetine group and combined group (risperidone+fluoxetine). They were assessed with Hamilton Depression Scale (HAMD), Treatment Emergent Symptom Scale (TESS) before treatment and in 2nd week, 4th week, 6th week and 8th week after treatment. Results The reduction rate of HAMD of combined group was the best among three groups(P<0.05), and that of fluoxetine group was better than that of risperidone(P<0.01). The significant difference in reduction rate of HAMD between combined group and other two groups was observed since 2nd week after treatment(P<0.05). No difference in scores of TESS has been observed in any time among three groups. Conclusion Risperidone can improve the efficacy of fluoxetine on depression without psychotic symptoms without increasing side effects, but itself is less effective than fluoxetine.

Objective:To investigate the clinical efficacy, safety and tolerance of different enteral nutritional therapy in the treatment of moderately severe acute pancreatitis (MSAP).Methods:From January 2018 to January 2019, 65 patients with MSAP who were hospitalized in Beijing Chao-Yang Hospital, Capital Medical University were prospectively enrolled. According to random number table, the patients were divided into the nasogastric tube enteral nutrition (NGEN) group (35 cases) and the nasojejunal tube enteral nutrition (NJEN) group (30 cases). All the patients received enteral nutrition solution through continuously pumping at a constant speed for 24 h. The two groups were compared in the relief time of abdominal pain, time from admission to receiving enteral nutrition treatment, time to resume oral feeding, computed tomography severity index (CTSI) score 1 week after enteral nutrition, nutrition status, infection parameters, hospitalization time, hospitalization expenses and complications. Independent sample t test and rank sum test of two independent samples were used for statistical analysis. Results:There were no significant differences in age, gender, body mass index (BMI), CTSI score and Ranson score at admission, relief time of abdominal pain, time from admission to receiving enteral nutrition treatment, time to resume oral feeding, CTSI score one week after enteral nutrition or hospitalization time between NGEN group and NJEN group (all P>0.05), and there was no death in both groups. The cost of hospitalization, catheterization time, cost of catheterization of NGEN group were all lower than those of NJEN group ((40.0±10.0) thousand yuan vs. (40.4±9.0) thousand yuan; 2.00 min (1.50 min, 2.50 min) vs. 11.50 min (9.50 min, 12.75 min); 135.42 yuan (135.42 yuan, 135.42 yuan) vs. 1 313.30 yuan (1231.20 yuan, 1 823.72 yuan)), and the differences were statistically significant ( t=2.342, Z=6.737 and 7.687, all P<0.01). The albumin levels of MSAP patients of the NGEN group at admission and 1 week after enteral nutrition were both higher than those of NJEN group ((43.5±5.1) g/L vs. (41.0±4.0) g/L, (42.1±4.1) g/L vs. (39.5±4.4) g/L), and the differences were statistically significant ( t=2.135 and 2.486, P=0.04 and 0.02), however there was no statistically significant difference in the decrease of albumin level between the two groups ( P>0.05). There were no statistically significant differences in the incidence of nutrition-related complications (abdominal distension, diarrhea, gastric retention and lumen obstruction) or the incidence of severe complications (transient organ failure and pancreatic necrosis complicated with infection) between NGEN group and NJEN group (all P>0.05). Conclusions:The efficacy and safety of NGEN are equivalent to NJEN in MSAP. Moreover, it can reduce the medical expenses of patients, and it is convenient to carry out in primary hospitals because of its easy operation.

Objective:To investigate the nutritional status of elderly inpatients in China, and to assess its relationship with clinical outcomes.Methods:A prospective, multicenter, parallel investigation was organized and conducted by the Chinese Medical Association's Group of Geriatric Nutrition Support.Patients aged ≥65 years from 30 major hospitals of 14 cities in China were evaluated by the Nutritional Risk Screening 2002(NRS2002)and the Mini-Nutritional Assessment-Short Form(MNA-SF), in order to understand the nutritional status and nutritional risk of elderly inpatients in China.The indicators of clinical outcomes were summarized, and the correlation between nutritional status and clinical outcomes was analyzed.Results:A total of 10 184 elderly patients who met the inclusion criteria were enrolled in this study, aged 65-112(74.81±7.01)years, with a body mass index(BMI)of 17.80-35.50(23.32±3.83)kg/m 2.Grip strength of the dominant hand was(16.95±18.42)kg, upper arm circumference was(25.68±3.70)cm, and calf circumference was(32.07±3.89)cm.BMI, grip strength, upper arm circumference and calf circumference decreased significantly with age( F=13.74, 97.47, 28.31 and 88.68, all P<0.001). NRS2002 was conducted on 10 182 patients.Of them, 10.14%(895/10 182)suffered malnutrition(BMI≤18.5 kg/m 2), and 46.42%(4 726/10 182)were at nutritional risk(NRS2002 score≥3). Nutrition deficiency and nutritional risk showed upward trends with age( F=43.41 and 177.05, both P<0.001). A total of 9 755 patients(95.79%, 9 755/10 182)completed the MNA-SF.Of them, 14.67%(1 431/9 755)had malnutrition, 35.04%(3 418/9 755)were at risk of malnutrition, and 50.29%(4 906/9 755)had normal nutritional status.The incidence of malnutrition and the risk of malnutrition significantly increased with age( F=172.79, 12.10 and 152.42, all P<0.05). Nutritional risk(NRS2002 score≥3)was related to age, BMI, mortality, infectious complications, length of hospital stay and total hospital cost(all P<0.05). Conclusions:The incidence of malnutrition and the risk of malnutrition are high in elderly inpatients in China.Nutritional risk is an influencing factor for adverse clinical outcomes.

Objective:
To observe the distribution of occupational activity disorders of extremely severe mass burn patients in recovery period after injury.
Methods:
From December 2014 to December 2015, 65 extremely severe burn patients conforming to the inclusion criteria involved in August 2 Kunshan factory aluminum dust explosion accident were admitted to Kunshan Rehabilitation Hospital. They received comprehensive rehabilitation treatment after burns, including wearing pressure clothes, ultrasound treatment, semiconductor laser and red light irradiation, motor function training, and so on. Over 2 years after injury, a cross-sectional survey was conducted on the patients′ occupational activity disorders. Modified Barthel index (MBI) was used to assess the degree of activities of daily living (ADL) disorder of patients and to grade the independent level of completing each item of MBI, and then the independent level of patients completing self-care MBI items (bathing, dressing, grooming, eating, going to the toilet, urine control, and stool control) was compared with that of mobility items (going up and down stairs, bed and chair transfer, and walking). The Canadian Occupational Performance Measure (COPM) was used to assess the distribution of occupational activity disorders of patients. The distribution of the five most serious occupational activity disorders was counted, then the frequency and probability of which with frequency greater than or equal to 16 times were calculated. Data were processed with Pearson Chi-square test.
Results:
Over 2 years after injury, the MBI score of patients was (76±22) points, and the ADL of 83.08% (54/65) patients reached completely self-care or light ADL disorder level. The MBI items arranged according to the completing independent level of patients from high to low were urine control/stool control, walking, bed and chair transfer, going up and down stairs, going to the toilet, eating, grooming, dressing, and bathing. The independent level of patients completing self-care MBI items was lower than that of mobility items (

Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder characterized by repeated abdominal pain and changes in defecation habits, which seriously affects the quality of life of patients. The occurrence and development of IBS are affected by many factors. As an inherent component of the gastrointestinal tract, eosinophils play a role in maintaining the local homeostasis of intestine. The activation of intestinal eosinophils plays a direct or indirect role in the occurrence and development of IBS. This article reviewed the progress of research on the potential role of eosinophils in IBS.

ObjectiveTo investigate the short-term knee function recovery of patients undergoing total knee arthroplasty (TKA) after discharge and analyze its related factors. MethodsFrom December, 2022 to April, 2023, 140 adult patients who underwent TKA in Nanjing Drum Tower Hospital and being about to be discharged were selected as the survey subjects using convenient sampling. Potential influencing factors were selected based on a literature review. They were investigated with general information questionnaire, Rehabilitation Exercise Compliance Scale, Self-Efficacy Scale for Rehabilitation Exercise (SER), Visual Analog Scale for pain (VAS), and joint range of motion measurements before discharge, and were investigated with the Hospital for Special Surgery Knee Score (HSS) one month after discharge. ResultsA total of 130 patients finished follow-up. One month after discharge, the HSS score ranged from 40 to 82, with an average of (70.89±6.26). Multiple linear regression analysis revealed that Body Mass Index (B = -0.423, 95%CI -0.622 to -0.224, P < 0.001), pre-discharge VAS (B = -1.016, 95%CI -1.198 to -0.113, P = 0.028), rehabilitation exercise compliance (B = 0.267, 95%CI 0.121 to 0.413, P < 0.001), SER (B = 0.478, 95%CI 0.315 to 0.642, P < 0.001), and knee joint flexion contracture angle (B = -0.251, 95%CI -0.414 to -0.088, P = 0.003) could influence HSS score one month after discharge (R2 = 0.615, F =17.106, P < 0.001). ConclusionPatients after TKA have recovered well in short time after discharge, however, there is still significant room for improvement. Clinical healthcare providers should design and implement appropriate interventions based on related factors to improve the function.

Curcumin is exclusively isolated from Zingiberaceae plants with a broad spectrum of bioactivities. In the present study, we used the diketide-CoA synthase (DCS) and curcumin synthase (CURS) genes to construct a non-natural fusion gene encoding diketide-CoA synthase::curcumin synthase (DCS::CURS). This fusion protein, together with the acetyl coenzyme A carboxylase (ACC) and the 4-coumarate coenzyme A ligase (4CL), were introduced into Escherichia coli for the production of curcumin from ferulic acid. The process is divided into two stages, the growth stage using LB medium and the fermentation stage using the modified M9 medium. The yield of curcumin reached 386.8 mg/L by optimizing the induction of protein expression in the growth stage, and optimizing the inoculum volume, medium composition and fermentation time in the fermentation stage, as well as the addition of macroporous resin AB-8 into the second medium to attenuate the toxicity of the end product. The exploitation of the non-natural fusion protein DCS::CURS for the production of curcumin provides a new alternative to further promoting the production of curcumin and the related analogues.
