Objective: To improve clinical utility of the Nurses Observation Sca le for Inpatient Evaluation (NOSIE-30) in China. Methods: Based on the original scale, which only provides names and ranked scores for items, we developed clear definitions for each item and anchoring descriptions for score rating. 164 firs t-episode schizophrenic patients were evaluated with this scale every two weeks after admission. A total of 994 evaluations were completed. The collected data w ere randomly divided into two independent data sets. The number and content of t he subscales were revised based on principal component factor analysis and item analysis of the first data set. The revised scale was then evaluated and compare d with the original 7-subscale version of the instrument using the second data s et. Results: Factor analysis found that the factor structu re of the revised scal e was markedly different from that of the original instrument. Item analysis res ulted in elimination of 30 original items and redistribution of the remaining 26 items into 5 subscales. Comparison of the revised scale with the original instr ument revealed better psychometric properties for the former than the latter.Conclusion: The subscale scores of the original 7-subscale v ersion of NOSIE-30 did not reflect independent symptom clusters in Chinese schizophrenic inpatients. T o improve the usefulness of the scale in China, the present study recommended a better revised scale with re-definition of items into 5 subscales.

Objective To evaluate the effect of wireless wearable intelligent body temperature monitoring system on temperature monitoring of perioperative patients. Method The body temprature of 572 patients with abdoiminal surgery who hospitalized in our hospital from June 2017 to Juanuary 2018 was measured by mercury thermometers and wireless intelligent body temprature monitoring system four times a day for three days with toally 6864 times after surgery.The measured time and data by both ways were compared and its relativity were analyzed. Results The measured data by mercury thermometers and wireless intelligent body temprature monitoring system was compared with no statistical significance (P>0.05), but the time measured by wireless intelligent body temprature monitoring system was shorter (P＜0.05). The measured data of two ways was postively related (r=0.962,P＜0.05). Conclusions The measurement results by the wireless wearable intelligent body temperature monitoring system are the same as by mercury thermometers. The accuracy of the system is well validated, and it can improve the working efficiency of nurses.

Objective: Traditional uterine manipulator is considered as the main reason for short survival of patients with early-stage cervical cancer during minimally invasive surgery. This study aims to assess the sealing effect of magnetic-sealing uterine manipulators (MUMs) in isolated uteruses. Methods: The study was performed on isolated uterus from patients with early-stage cervical cancer who underwent open abdominal radical hysterectomy between November 2019 to April 2021. Right-angle forceps closure tests (groups 1 and 3) were defined as control tests. One experimental MUM closure test (group 2) and 2 control tests were respectively carried out in each of the isolated uterus. DNA ploidy analysis system was used to observe exfoliated cells. Statistical analysis was performed using Wilcoxon signed-rank test to assess the sealing effect of MUM. Results: We identified 36 patients. No regional node metastasis was discovered and only one tumor was larger than 4.0 cm in diameter. The mean of exfoliated tumor cells in groups 1, 2, and 3 were 1, 1, and 2, respectively. There was no significant difference in the quantity of exfoliated cells between groups 1 and 3 (p=0.476), so the results of the 2 groups were merged. Subsequently, a significant difference was observed between combined right-angle forceps closure tests and MUM closure tests (p=0.022). Conclusion The sealing effect of MUM was better than that of right-angle forceps. MUM can effectively seal cervical cancer cells in the cup cover, avoiding the dissemination of tumor cells.

Objective To explore the efficacy of the single versus combination drug therapies for benign prostatic hyperplasia(BPH) combined with overactive bladder(OAB).Methods A total of 471 outpatients with BPH and OAB meeting the inclusion/exclusion criteria were enrolled in this prospective cohort study from March 2012 to October 2015.Patients were divided into two groups:(1) the single alpha-blocker treatment group (prostate volume ＜ 30 ml),and (2) the 5 alpha reductase inhibitors(5-ARIs) plus alpha-blocker combination treatment group(prostate volume ≥ 30 ml).The 318 patients were treated with alpha blockers for 4 weeks,and then received a continuing alpha-blocker treatment for 8 weeks if IPSS score changes were less than 30％ (i.e.single alpha-blocker treatment group).And 153 patients were treated with 5-ARIs for 12 weeks,then received 5-ARIs plus alpha-blocker combination treatment for another 4 weeks(a total of 16 weeks)if IPSS score changes were less than 30 ％ (i.e.combination treatment group).The improvements of post-voiding residual(PVR),PV,maximum urinary flow rate(Qmax),international prostate symptom score(IPSS),overactive bladder symptom score (OABSS),quality of life (QOL),urine storage period symptom score (USPSS) and voiding symptom score(VSS)were compared between the two groups.Results The values of IPSS,OABSS,QOL,USPSS and VSS index in the two groups were improved after treatment as compared with pre-treatment(all P≤0.05).Patients in combination treatment group had little improvement in PVR and Qmax after treatment.The OAB symptom remission rates of BPH patients with OAB in single alpha-blocker treatment group were 70.5％ (206/292)and 78.6％ (165/210)after 4 and 12 weeks of treatment respectively.The OAB symptoms remission rates of BPH patients with OAB in combination treatment group were 54.5 ％ (64/122) and 67.1％ (53/79) after 12 and 16 weeks of treatment respectively.Conclusions Both single alpha-blocker treatment and alpha-blocker plus 5ARIs combination treatment,which identification was based on prostate volume,have good effects on BPH patients with OAB.The single alpha-blocker treatment can improve PVR and Qmax,and the alpha-blockers plus 5ARIs combination treatment can improve the prostate volume in BPH patients with OAB.

AIM:To observe how total flavonoids of Pterocarya hupehensis Skan(PHSTF)affects the migra-tion and invasion of human rheumatoid fibroblast-like synoviocyte line MH7A.METHODS:The MH7A cells were divided into control group(without any treatment),low-,medium-and high-dose(6.25,12.5 and 25 mg/L,respectively)PHSTF groups,phosphatidylinositol 3-kinase(PI3K)inhibitor 740Y-P(10 μmol/L)group,and 740Y-P(10 μmol/L)+high-dose(25 mg/L)PHSTF group.The viability of the MH7A cells was determined by CCK-8 assay,while the migration and inva-sion were assessed by scratch and Transwell assays.The protein levels of matrix metalloproteinase-2(MMP-2),MMP-9,PI3K,p-PI3K,AKT and p-AKT were detected by Western blot.RESULTS:Compared with control group,the cell via-bility in PHSTF treatment groups was reduced(P<0.05),the cell wound healing area was significantly decreased(P<0.01),migratory and invasive cells in the lower chamber were significantly reduced(P<0.01),and the protein expres-sion of MMP-2 and MMP-9 and the ratios of p-PI3K/PI3K and pAKT/AKT were decreased(P<0.01).Compared with high-dose PHSTF group,the addition of PI3K/AKT pathway agonist 740Y-P significantly increased the migration and invasion ability of MH7A cells(P<0.01)and elevated the protein expression of MMP-2 and MMP-9 and the ratios of p-PI3K/PI3K and pAKT/AKT(P<0.01)under the treatment with PHSTF.CONCLUSION:Total flavonoids of Pterocarya hupehensis Skan could inhibit the migration and invasion of MH7A cells by regulating the PI3K/AKT signaling pathway.

ObjectiveBased on the antidepressant activity， the optimal ratio of Rehmanniae Radix and Lilii Bulbus in Baihe Dihuangtang was optimized and its possible mechanism was preliminarily explored. MethodA total of 100 male mice were randomly divided into normal group， model group， Rehmanniae Radix single decoction group， Lilii Bulbus single decoction group， and 5 different ratios of Baihe Dihuangtang group （Rehmanniae Radix-Lilii Bulbus 5∶6， 5∶5 ， 5∶4， 5∶3， 5∶2）， fluoxetine hydrochloride group. Except for the normal group， the remaining 9 groups were treated with chronic unpredictable mild stress method （CUMS） for 21 consecutive days to establish the depression mouse model.The Rehmanniae Radix single decoction group， Lilii Bulbus single decoction group and 5 different ratios of Baihe Dihuangtang group were administered with corresponding drugs at a dose of 2 g·kg^-1 respectively， and fluoxetine hydrochloride group was administered fluoxetine hydrochloride at a dose of 0.01 g·kg^-1， the normal group and the model group were respectively given an equal volume of normal saline by gavage for 21 consecutive days. The antidepressant effect of Baihe Dihuangtang with different ratios was evaluated by behavioral experiments. Western blot was used to detect the expression levels of brain-derived neurotrophic factor （BDNF） and tyrosine kinase receptor B （TrkB） in hippocampus. The level of total superoxide dismutase （SOD） in hippocampus was detected by hydroxylamine method. The level of reduced glutathione （GSH） in hippocampus was detected by spectrophotometric method. The levels of glutathione peroxidase （GPX） and glutathione S-transferase （GST） in hippocampus was detected by colorimetric method. The level of malondialdehyde （MDA） in hippocampus was detected by thiobarbituric acid method， and preliminary exploration of its antidepressant mechanism. ResultCUMS caused a significant decrease in the preference rate of sugar water and a significant prolongation of forced swimming and tail suspension immobility time （P<0.01）， while the different ratios of Baihe Dihuangtang and the single decoction of Rehmanniae Radix and Lilii Bulbus were significantly reversed to varying degrees. Abnormalities of the above indicators were observed （P<0.05， P<0.01）， especially when the ratio of 5∶6 had the most obvious effect on the above indicators， Moreover， CUMS caused the hippocampal BDNF and the expression of TrkB， SOD and glutathione antioxidant-related indexes were significantly decreased （P<0.01）， and the levels of lipid peroxidation product MDA was significantly increased （P<0.01）. However， the superior ratio of Baihe Dihuangtang （Rehmanniae Radix-Lilii Bulbus 5∶6， 5∶5， 5∶4） and the single decoction of Rehmanniae Radix and Lilii Bulbus significantly reversed the abnormality of the above indicators to varying degrees （P<0.05， P<0.01）. ConclusionIn summary， 5 different ratios of Baihe Dihuangtang and the single decoction of Rehmanniae Radix and Lilii Bulbus can produce antidepressant effect， especially when the ratio of 5∶6 had the most obvious effect on the above indicators， and the antidepressant effect gradually weakens with the proportion of Lilii Bulbus in the recipe decreases， and its mechanism may involve enhancing the nutritional level and antioxidant defense ability of hippocampal central nervous system.
