OBJECTIVE:To explore the role of clinical evidence-based pharmacy in anticoagulant treatment strategies during continuous renal replacement therapy (CRRT). METHODS:Taking a thrombocytopenia patient of anticoagulant treatment during CRRT for instance,clinical pharmacists analyzed the evidence of taken argatroban anticoagulant therapy during CRRT for high risk blooding and thrombocytopenia patients based on evidence-based pharmacy combined with clinical data,monitored the efficacy and safety and evaluated the treatment process. RESULTS:Totally five literature about anticoagulant treatment strategies during CRRT for high risk blooding and thrombocytopenia patients were obtained,including one systematic review,one RCT and three cohort studies. Based on the above evidences,good results were achieved in the clinical practice of this patient,no thrombotic or hemor-rhagic complications occurred in this patient,platelet count and coagulation indicators of patients also improved. CONCLUSIONS:Evidence-based pharmacy plays an important role in anticoagulant treatment strategies during CRRT.

Langerhans cell histiocytosis is an uncommon disease, involvement of the thyroid by langerhans cell histiocytosis is rare. Two cases of Langerhans cell histiocytosis of the thyroid confirmed by pathology were reported in this paper. The main clinical feature was enlargement of the thyroids. One patient had hypothyroidism. Meanwhile, the lungs and pituitaries of the two patients were affected. Langerhans cell histiocytosis of the thyroid had no typical symptoms and specific laboratory examination, and might be clinically diagnosed as chronic lymphocytic thyroiditis, benign or malignant thyroid tumors. Thyroid fine needle aspiration cytology might be useful in confirming the diagnosis. The effective treatments include systemic chemotherapy, local radiation therapy and surgical excision. The chemotherapy is still the major technological approach. Most patients can relieve partially after receiving the systemic chemotherapy.

Objective To investigate the effect of curcumin on the expression of cannabinoid receptor 1 (CBR1) and NR2B subunit-containing NMDA receptor in spinal cord dorsal horn and dorsal root ganglion (DRG) neurons in a rat model of neuropathic pain.Methods Seventy-two male Sprague-Dawley rats,weighing 200-230 g,were randomly divided into 4 groups ( n =18 each):sham operation group (S group),chronic constrictive injury (CCI) group,curcumin group (Cur group) and solvent control group (SC group).Neuropathic pain was induced by CCI.The sciatic nerve was exposed and 4 loose ligatures were placed on the sciatic nerve at 1 mm intervals in groups CCI,Cur and SC.Curcumin was injected intraperitoneally at 100 mg· kg- 1· d-1 for 14 consecutive days after operation in Cur group,while the equal volume of dimethyl sulfoxide was given instead of curcumin in SC group.Mechanical withdrawal threshold (MWT) and thermal withdrawal latency (TWL) were measured on 2 days before operation and on 1,3,7,10 and 14 days after operation.Six rats in each group were sacrificed on 3,7 and 14 days after operation and the lumbar segments of the spinal cord ( L4,5 ) and DRGs were removed to determine the expression of CBR1 and NR2B by immuno-histochemistry.Results Compared with S group,MWT was significantly decreased,TWL was significantly shortened,and the expression of CBR1 and NR2B in spinal cord dorsal horn and DRG neurons was up-regulated after operation in the other three groups (P ＜ 0.05 ).Compared with CCI group,MWT was significantly increased,TWL was significantly prolonged,the expression of CBR1 inspinal cord dorsal horn and DRG neurons was up-regulated,and the expression of NR2B in spinal cord dorsal horn and DRG neurons was down-regulated after operation in group Cur (P ＜ 0.05 ),and no significant change in the parameters mentioned above was found in group SC ( P ＞ 0.05 ).Conclusion Curcumin can alleviate neuropathic pain in rats,and up-regulation of CBR1 expression and down-regulation of NR2B expression in spinal cord dorsal horn and DRG neurons are involved in the mechanism.

Objective To assess the applicative effect of the flipped classroom in nutrition and food hygiene. Methods 48 students of Class One from Grade 2011 majoring in preventive medicine were taken as the TBL group, with 49 students of Class Two as the flipped classroom group. The TBL group used TBL and the formative assessment, while the flipped classroom group used the flipped classroom and the forma-tive assessment. The teaching effect was evaluated through the unified examination and teaching satisfaction questionnaire survey. SPSS 17.0 statistical software was used for the data t test between the groups, and Wilcoxon test, chi square test were used for the linear correlation analysis of the usual grade and final grade of the flipped classroom group. Results The experimental scores (9.21 ±1.14) and the final scores (66.76±4.53) of the flipped classroom group students were significantly higher than the experimental scores (8.31±1.01) and final scores (61.31±4.37) of the TBL group and the difference was statistically significant (t=4.50, P=0.004; t=5.45, P=0.003). The excellent distribution of the flipped classroom group's overall results were higher than that of the TBL group (u=21.36, P=0.002). The usual scores and the final scores were positively correlated (r=0.960, P=0.000) in the flipped classroom group. The results of the question-naire showed that the flipped classroom group students' satisfaction with the positive impact the teaching methods had on all aspects of their own was higher than that of TBL group (P<0.05). Conclusion The flipped classroom teaching can help improve the students' learning enthusiasm, thinking activity and com-municative competence.

Objective To investigate the effect of curcumin on apoptosis in hippocampal neurons and the expression of c-Jun N-terminal kinase 3 (JNK3) and postsynaptic density protein 95 (PSD95) in hippocampus during cerebral ischemia-reperfusion (I/R) in rats with spontaneous hypertension (SH) .Methods One hundred and thirty-five male rats (homologous with WKY) with SH and 90 male normotensive WKY rats, weighing 275-325 g,were used in this study. The WKY rats were randomized into 2 groups ( n = 45 each) : sham operation group (WS group) and cerebral I/R group (W-I/R group) . The rats with SH were randomly divided into 3 groups ( n = 45each) : sham operation group (S-S group), cerebral I/R group (S-I/R group) and curcumin group (S-C group) .Global cerebral ischemia was produced by 4 vessel-occlusion method. The bilateral common carotid arteries were only exposed but not ligated in W-S and S-S groups. Intraperitoneal corn oil 10 ml/kg was injected at 30 min of reperfusion in W-I/R and S-I/R groups. Intraperitoneal curcumin 100 mg/kg was injected at 30 min of reperfusion in S-C group. Three animals in each group were sacrificed at 2 h, 6 h, 1 d, 3 d and 7 d of reperfusion and their brains were harvested for determination of apoptosis in hippocampal neurons and the expression of JNK3 and PSD95in hippocampus. Results The number of apoptotic neurons was significantly increased in S-S group compared with W-S group ( P < 0.05) . The number of apoptotic neurons was significantly increased and the expression of JNK3was up-regulated in S-I/R group compared with S-S group ( P < 0.05) . The number of apoptotic neurons was significantly decreased and the expression of JNK3 was down-regulated in S-C group compared with S-I/R group (P <0.05) . There was no significant difference in the expression of PSD95 among all the groups ( P > 0.05) . Conclusion Curcumin can inhibit apoptosis in hippocampal neurons and the mechanism is related to down-regulation of the expression of JNK3 in hippocampus. The mechanism by which curcumin down-regulates the expression of JNK3in hippocampus may not be related to PSD95 pathway.

Objective To observe the effect of core stability training on motor function, balance and activities for children with cerebral palsy. Methods 100 children with cerebral palsy were divided into control group (n=50) and treatment group (n=50). The control group accepted routine physical therapy, occupational therapy, acupuncture, sensory integration training and conductive education; while the treatment group accepted core stability training in addition, 3 hours a day for 12 weeks. They were assessed with Gross Motor Function Measure (GMFM-88), Berg Balance Scale (BBS) and Comprehensive Functional Assessment for Disabled Children (CFA-DC) before and after treatment. Results The scores of GMFM-88, BBS and CFA-DC improved more in the treatment group than in the control group (P<0.05). Conclusion Core stability training can further promote the recovery of motor, balance and activities in children with cerebral palsy.

We reported a case of hypophysitis caused by a programmed death-1 ( PD-1) inhibitor. The patient was a 59-year-old female with metastatic malignant melanoma who participated in the phaseⅡclinical trial of a PD-1 inhibitor toripalimab. More than five months after the administration of toripalimab,she experienced fatigue, depression, nausea, and anorexia. Laboratory examinations showed mild hyponatremia, secondary adrenal insufficiency, and secondary hypothyroidism. MRI revealed the enlargement of her pituitary with obvious enhancement. The patient was diagnosed as hypophysitis caused by the PD-1 inhibitor and was given replacement therapy with physiological doses of corticosteroid and levothyroxine sodium. Her symptoms were then improved. MRI revealed that her pituitary size returned to normal after 8 weeks of treatment and remained stable during every 3-month follow-up. This case reminds us of the possibility of hypophysitis when patients suffere from fatigue and anorexia during the process of PD-1 inhibitor treatment. Correct diagnosis, proper therapy, and regular follow-up are important to ensure the patients' safety, and to improve their prognosis.

Objective To compare the dose, clinical efficacy and acute adverse reactions of intensity modulated radiotherapy(IMRT)and three-dimensional conformal radiotherapy(3D-CRT)combined with three-dimensional brachytherapy (3D-BT) in the treatment of concurrent radiotherapy and chemotherapy for advanced stage cervical cancer patients. Methods Data collection was performed from January 2011 to November 2015 in Chinese PLA General Hospital and Inner Mongolia Cancer Hospital.All 89 patients with advanced stage (Ⅱb-Ⅲb) cervical cancer were treated by pelvic radiotherapy and concurrent chemotherapy, 46 cases of them received IMRT and 3D-BT(IMRT group), 43 cases received 3D-CRT and 3D-BT(3D-CRT group),along with cisplatin chemotherapy.The dose accumulation of external beam radiotherapy and 3D-BT was calculated by deformable image registration to analyze clinical efficacy, acute adverse reactions and prognosis of the two groups.Results (1)Dose of radiotherapy:planning target volume(PTV)coverage of IMRT group and 3D-CRT group were respectively(95.4±4.7)% and(95.1±5.1)%, without significant differences (t=0.289, P=0.773). Compared with the patients treated with 3D-CRT, the volumn receiving at least 30 Gy (V30), V50of rectum, colon, bladder and small intestine and V20of bone marrow in the IMRT group were significantly decreased (P<0.05). Regarding the combined dose, the maximum dose (Dmax) and the minimum dose received by the most exposed 2 cm3volume of the analyzed organ(D2CC)of rectum,colon,bladder and small intestine of IMRT group were significantly lower than those of 3D-CRT group (P<0.05). (2) Short-term efficacy: the effective rate of IMRT and 3D-CRT group were respectively 93% (43/46) and 91% (39/43), with no significant differences (χ2=0.237,P=0.626). (3) Acute adverse reactions: compared with 3D-CRT, IMRT could significantly reduce grade 1-2 acute toxicity in gastrointestinal [63%(29/46) vs 84%(36/43)], genitourinary [17%(8/46) vs 37%(16/43)] and hematologic [57%(26/46) vs 79%(34/43)] system (all P<0.05). There were no significant differences of grade 3 acute adverse reactions of gastrointestinal,genitourinary and hematologic system between two groups(all P>0.05). No grade 4 acute adverse reactions were observed. (4) Prognosis: the overall survival rate at 1, 2-year of IMRT and 3D-CRT group were respectively 95.6%,89.1% and 93.1%,86.1%.The progression-free survival rateat 1, 2-year of IMRT and 3D-CRT group were 91.1%, 89.1% and 88.4%, 86.1%, respectively. There were no significant differences in overall survival rate and progression-free survival rate between two groups (P>0.05). Conclusions Compared with 3D-CRT, IMRT combined with 3D-BT has dosimetry advantages based on dose accumulation algorithms by deformable image registration. IMRT could ensure clinical efficacy and significantly reduce the incidence rate of acute toxicities.

OBJECTIVETo investigate the possible effects of long-term exposure to dust containing thorium and thoron progeny on dust-exposed miners.

METHODSA negative, high voltage, exhaled thoron progeny measurement system was used to estimate the miners' thorium lung burden.

RESULTSThe highest thorium lung burden of 638 miners was 11.11 Bq. The incidence of stage 0(+) pneumoconiosis was higher among dust-exposed miners. Lung cancer mortality of the dust-exposed miners was significantly higher than that of controls (P < 0.005).

CONCLUSIONThere is a difference in cancer rates between those who have long-term exposure to dust containing thorium (in which carcinogenic ThO(2) and SiO(2) exist) and thoron progeny and those who have not.
