Objective:To explore the effect of low-molecular-weight heparin calcium in preventing lower limb deep vein thrombosis after rectal cancer surgery.Methods:A retrospective case-control study was conducted. The clinical data of 30 rectal cancer patients with postoperative subcutaneous injection of low-molecular-weight heparin calcium in Beijing Hepingli Hospital from February 2018 to February 2022 were retrospectively analyzed, and 30 patients wearing antithrombotic elastic socks during the same period were selected as controls. In the antithrombotic elastic socks group, the appropriate thrombotic elastic socks were selected according to the actual situation of the patients after operation. Low-molecular-weight heparin calcium group was given subcutaneous injection of low-molecular-weight heparin calcium on the 2nd day after operation. The indexes of coagulation function, situation of postoperative lower limb deep vein thrombosis and perioperative indexes were analyzed.Results:The age of patients in the low-molecular-weight heparin calcium group was (62±12) years old, with 17 women and 13 men. The age of patients in the antithrombotic elastic socks group was (63±1) years old, with 18 women and 12 men. Before prevention, there were no significant differences in platelet count (Plt), activated partial thromboplastin time (APTT), thrombin time (TT), prothrombin time (PT), fibrinogen (FIB), D-dimer (D-D) levels between the two groups (all P > 0.05). After prevention, the FIB and D-D levels of patients in the low-molecular-weight heparin calcium group [(3.3±0.7) g/L and (341±30) μg/L] were lower than those in the antithrombotic elastic socks group [(4.9±0.6) g/L and (428±40) μg/L] ( t values were 9.51 and 9.61, both P < 0.05), but there were no significant differences in Plt, APTT, TT and PT between the two groups (all P > 0.05). The rate of lower limb deep vein thrombosis in the low-molecular-weight heparin calcium group was lower than that in the antithrombotic elastic socks group [6.67% (2/30) vs. 26.67% (8/30), χ2 = 4.32, P < 0.05]. The drainage flow of anterior sacral drainage tube in the two groups decreased gradually on the 1st, 2nd, 3rd and 4th day after surgery, but there were no significant differences between the two groups (all P > 0.05). The thrombosis time of patients in the low-molecular-weight heparin calcium group was longer than that in the antithrombotic elastic socks group [(84±9) h vs. (73±10) h, t = 4.81, P < 0.05], but there were no significant differences between the two groups in the intraoperative bleeding amount, operation time and postoperative hospital stay (all P > 0.05). Conclusions:Compared with antithrombotic elastic socks, low-molecular-weight heparin calcium is more effective and safer in the prevention of lower limb deep vein thrombosis after rectal cancer surgery.

Objective To explore the role of clinical pharmacists in the treatment of drug poisoning by analyzing the clinical pharmacist's participation in the treatment of a patient with sodium valproate poisoning. Methods Clinical pharmacists measured the plasma concentration of sodium valproate to inform the doctor to diagnose illnesses. At the initial stage when the concentration is high, to eliminate the free drug by continuous venous-venous hemodialysis-filtration (CVVHDF). Then, the combined drug was cleared by hemoperfusion (HP). Results The blood concentration dropped by half at the first CVVHDF and decreased obviously after two HPs. After stable observation in five days’ course of disease, the blood concentration was maintained at a low level and the patient was cured and discharged. Conclusion The implementation of the blood purification program under the monitoring of the blood drug concentration with the participation of pharmacists is helpful for the rescue of drug overdose and is worthy of promotion.

Objective:To synthesize a 68Ga-labeled oxalyldiaminopropionic acid (ODAP)-urea based prostate specific membrane antigen (PSMA) targeting probe, and evaluate its properties in vitro and in vivo. Methods:Ligand P151 was synthesized by solid-phase synthesis and its Ki value was determined. The ligand P151 was added into the mixture of 68GaCl 3 and NaOAc solution and was reacted at 95 ℃ for 10 min. The labeling yield and in vitro stability of 68Ga-P151 were determined by high performance liquid chromatography (HPLC). The lipid-water partition coefficient (log P) and cell binding ability were determined. The biodistribution of 68Ga-P151 in normal KM mice was determined. MicroPET imaging of 68Ga-P151 was carried out in prostate cancer 22Rv1 tumor-bearing mice and compared with 68Ga-PSMA 617. Independent sample t test was used to analyze the data. Results:P151 was successfully synthesized with the Ki of 0.58 nmol/L, the labeling yield more than 95% and the radiochemical purity more than 95%. After placement in saline or human serum albumin (HSA) solution at 37 ℃ for 2 h, the radiochemical purity of 68Ga-P151 was still more than 95%, indicating a good stability in vitro. The lipid-water partition coefficient (log P) of 68Ga-P151 was -2.65±0.17, indicating a good hydrophilicity. 68Ga-P151 specifically bound to PSMA in prostate cancer LNCaP cells with the uptake value of (0.83±0.04) percentage injection activity (%IA)/10 5 cells. Biodistribution of normal mice showed that 68Ga-P151 was mainly excreted through kidneys and other organs showed low uptake. MicroPET imaging of tumor-bearing mice showed the maximum standardized uptake value (SUV max: 0.79±0.23 vs 0.54±0.05; t=2.12), tumor/kidney ratio (2.04±0.65 vs 1.88±0.33; t=0.44) and tumor/muscle ratio (12.83±5.18 vs 6.95±1.63; t=2.17) between 68Ga-P151 and 68Ga-PSMA 617 were not significantly different (all P>0.05). Conclusions:68Ga-P151 can be prepared simply and labeled in high yield and show improved pharmacokinetic properties in vivo. The imaging of 68Ga-P151 on PSMA positive tumor is comparable to that of 68Ga-PSMA 617, making it a potential radiopharmaceutical for the diagnosis of prostate cancer.

Objective To investigate the effect of delighted thinking on improving negative emotion of depression patients. Methods 100 depression patients were randomly divided into the observation group and the control group with 50 in each according to admission sequence. Both groups was executed antidepressionant drugs treatment and routine psychiatric care simultaneously. The observation group was given delighted thinking training on the basis of above treatment. The emotional recovery of two groups was observed. Results There was significant difference on facial expression, communication and limbs language after executing delighted thinking training in the observation group. And there was significant difference on scores of Hamilton depression rating scale (HAMD) at discharge. Scores of Nurses' Observation Scale during early, middle and late stage of delighted thinking training greatly improved compared with those before training. Conclusions Delighted thinking contributes to throw off negative thinking pattern of self-denial, stimulate positive passion threshold, improve depressed mood and raise treatment effect for depression patients.

Dysentery is one of the digestive system diseases, which has a higher incidence rate. The aim of present study was to further explore the incidence of dysentery and get the better prevention of this disease. The data were collected and statistically analyzed from Shaanxi Province for the monthly incidence of dysentery in 22 years. In addition, according to the Yunqi theory and related incidence of diseases, the correlation between the incidences of dysentery and Suiyun, Sitian, Zaiquan and Six-qi were summarized systematically. This study provides a reference for the incidence of dysentery.
