Forty eight patients in the control group from February to August, 2018 were treated with traditional management. From February to August, 2019, 48 patients in the research group adopted the accelerated rehabilitation information management system based on data-driven technology, which can automatically match, interact and push the information between medical and patient.Results:The Self-rating Anxiety Scale(SAS) score of the intervention group on hospitalization day was 41.52±4.65, which was better than that of the control group (52.60±4.84). The difference between the two groups was statistically significant ( F value was 11.446, P<0.05). The scores of Hospital for Special Surgery(HSS), Visual Analogue Scale(VAS) and SAS in the intervention group 3 days after operation were 56.31±5.81, 2.79±0.68, 38.69±3.81, which were better than those of the control group (51.31±5.20, 4.31±0.78, 46.02±3.86). The difference between the two groups was statistically significant ( F value was 4.44, 10.19, 9.37, all P<0.05); the HSS, VAS, and SAS scores of the intervention group one week after operation were 71.35±3.59, 1.98± 0.67, 36.81±4.03, better than the control group (67.15±3.67, 2.60±0.87, 39.48±4.04), the difference between the two groups was statistically significant ( F value was 5.683, 3.951, 3.237, all P<0.05); the postoperative hospital stay in the intervention group was (3.98±0.84) days, which was less than (6.00±0.80) days in the control group, the difference was statistically significant ( F value was 146.286, P<0.05); The patients′ satisfaction score in the intervention group during medical treatment was 97.46±1.73, which was higher than the control group (94.35±2.04), the difference was statistically significant ( F value was 64.911, P<0.05). Conclusions:TKA enhanced recovery management system based on "cloud + terminal" data-drivene can improve the management level of TKA patients, reduce the length of stay and improve satisfaction of patients.

Objective: To report a case of rat poison with multiple hemorrhage after trauma. Methods: The clinical data of a case of rodenticide poisoning with hemorrhage as the first symptom admitted to a third-class a hospital in July 2018 were analyzed and summarized. Results: This patient is a rodent drug poisoning patient with hemorrhage as the first symptom.The disease was diagnosed as bromohamelin and bromadiolone poisoning through the analysis of poison detection because the rodent drug was taken in the market and the history of taking poison was concealed. The patient was given active comprehensive treatment of vitamin K1 and other drugs for clinical cure. Conclusion For patients with clinically unexplained hemorrhage, the possibility of rodenticide poisoning should be considered and the toxicant detection should be improved actively.

Objective To evaluate the effect of integrated service platform of extensional care based on the combined internet and extensional care model in the orthopedics nurse care. Methods Two hundred and eighty six hospitalized patients in the orthopedic department were randomly divided into two groups including experimental group (144 cases) and control group (142 cases) according to the random number table method. Patients in the control group received extensional care by traditional telephone follow-up, patients in the experimental group received extensional care by using the integrated service platform combing internet and extensional care. All the patients were evaluated using the self-made extensional care satisfaction questionnaire and Short Form 36 Questionnaire. Results The extensional care satisfaction scores of experimental group using internet plus extended care mode were respectively ( 74.4 ± 5.3) points and (76.2 ± 8.1) points at the time points of 3 months and 6 months after discharge from hospital;The extensional care satisfaction scores of control group were respectively (69.4±9.9) points and (70.1±12.2) points at the time points of 3 months and 6 months after discharge from hospital;The two groups had statistically comparative difference (t=7.40, 6.37, P<0.01). There was a statistically significant improvement of extensional care satisfaction and physical function score and role-physical score and social function score in the experimental group compared with the control group both at the time points of 3 months and 6 months after discharge from hospital. There was a statistically significant improvement of vitality score and role-emotion score in the experimental group compared with the control group both at the time points of 1 month and 3 months after discharge from hospital (t=2.366-8.211, P<0.05). Conclusions The effect of integrated service platform of extensional care based on the combined internet and extensional care model is better than traditional telephone follow-up, patients′satisfaction is higher. This new mode of service platform could greatly deepen the connotation of quality nursing, intensify the effect of extensional care, and reduce the working strength of nurse who did extensional care as while.

[ ABSTRACT] AIM:To investigate the antipyretic effect of patchouli oil on lipopolysaccharide ( LPS)-induced fe-ver in rabbits.METHODS:Male rabbits (n=42) were randomly divided into 7 groups according to their body weight and basal body temperature, including control group, model group, western medical positive group, traditional Chinese medical positive group, and high, middle and low doses (2%, 1%and 0.5%) of patchouli oil groups.Subsequently, except the controls, the rabbits were injected with LPS at a dose of 1 mL/kg (2 mg/L) through marginal ear vein to establish rabbit fever model and the rabbits in control group received the same volume of NS.The rabbits in control group and model group were injected with 0.5%Tween-80 0.5 h late, and the rabbits in the other groups were treated with correspoonding drugs. The effect of patchouli oil on the body temperature was observed, and the levels of interleukin-1β( IL-1β) and tumor nec-rosis factor-α(TNF-α) in the serum, and prostaglandin E2(PGE2) and cyclic adenosine monophosphate (cAMP) in the hypothalamus were measured by radioimmunoassay.RESULTS: The body temperature and the levels of IL-1β, TNF-α, cAMP and PGE2 in model group were significant higher than those in control group.Patchouli oil notably inhibited the body temperature in the febrile rabbits.From 1.5 h to 5.5 h after administration, the body temperatures were increased by (1.06 ±1.55), (1.62 ±1.36), (1.38 ±1.22), (0.98 ±0.98) and (0.48 ±0.95) ℃in high patchouli oil group, re-spectively.From 3.5 to 5.5 h after administration, the body temperatures were elevated by ( 1.47 ±0.73 ) , ( 1.15 ± 0.68) and (0.63 ±0.54) ℃ in middle patchouli oil group, respectively.A tendency of downregulation of the elevated body temperatures was observed at every time point after administration in low patchouli oil group.Patchouli oil significantly decreased the levels of TNF-αin the serum and cAMP content in the hypothalamus, and attenuated the elevated tendency of the IL-1βlevel in the serum and PGE2 level in the hypothalamus.CONCLUSION:Patchouli oil evidently has antipyretic effect on LPS-induced fever in the rabbits.The antipyretic mechanism might be related to the inhibition of TNF-αlevel in serum and cAMP content in the hypothalamus.

To investigate the relationship between plasma level of homocysteine(Hcy) and the methylenetetrahydrofolate reductase ( MTHFR ) gene polyroorphism with non-alcoholic fatty liver in patients with type 2 diabetes mellitus (T2DM). Methods In a case-control study, plasma levels of Hcy, folic acid (FA), vitamin B12 (VitB12), glycosylated hemoglobin Alc (HbAlc), fasting blood glucose (FBG), total cholesterol and triglyceride were measured in 159 T2DM patients with and without non-alcoholic fatty liver ( NAFL), as well as 52 normal controls. Mutation of the C677T of MTHFR gene was determined by polymerase chain reaction-restricted fragment length polymorphism (PCR-RFLP) for all of them. Results Patients of T2DM both without NAFL (96 case) and with NAFL had higher prevalence of hyperhomocysteinemia (Hhcy) (49% and 21%, respectively ) than normal controls did (4 cases, 8% ) (P<0.05), while patients of T2DM with NAFL had higher prevalence of Hhcy than those without it did (P <0. 05). Plasma level of Hey positively correlated to genotype frequency of the MTHFR gene, plasma 0levels of HbAlc and FBG in patients of T2DM, with coefficients of correlation of 0.248, 0.423 and 0.242, respectively (P < 0.05). Results of multiple logistic regression analysis showed that course of the disease, body mass index, plasma levels of FBG and Hcy all were independent risk factors for non-alcoholic fatty liver in patients with T2DM. Conclusions Hhey was an independent risk for non-alcoholic fatty liver and plasma level of Hey was influenced by frequency of the TT genotype of the MTHFR gene, plasma levels of FA and VitB12, as well as metabolic disturbance in patients with T2DM.

The relation of methylenetetrahydrofolate(MTHFR)reductase C677T polymorphism with primary hyperuricemia and gouty arthritis was observed in People's Hospital of Shanxi Province.MTHFR reductase C677T pdymorphism in 195 subjects was examined by PCR-restriction fragment length polymorphism.The results showed that MTHFR gene mutation might be a risk factor for primary hyperuricemia.However,C677T polymorphism of the MTHFR gene was not related to the development of gouty arthritis.

To evaluate the validity of osteoarthritis model induced by bilateral ovariectomy in guinea pig, 32-month-old female guinea pigs were randomly divided into two groups: a sham operation group (control group) and an ovariectomized group (OVX group). The animals were killed 6 or 12 weeks after the operation and the degeneration of the knees were assessed microscopically and histologically by scanning electron microscope (SEM), transmission electron microscope (TEM) and light microscope. The serum levels of estrogen and gestone were detected by immune contest assay. The scoring of articular cartilage histopathology of tibial plateau was performed by histopathological examination. The blood serum levels of estrogen and gestone were decreased significantly in the OVX group as compared with the control group 6 or 12 weeks after the operation. Joint cartilage degeneration as detected by SEM and TEM could be found at the 6th week, but severe degenerative lesions were observed at the 12th week in the OVX group as compared with the control group (P<0.01). The histopathological score of articular cartilage in tibial plateau in OVX group was higher than that of control group, which was coincident with the changes of estrogen and the ultrastructure (P<0.01). The findings suggested that bilateral ovariectomy in guinea pig can induce the severe osteoarthritis that is similar to the aging-induced OA in human. Therefore, the model of the osteoarthritis by bilateral ovariectomy in guinea pig in this study is valid.
