Objective:To construct a fuzzy comprehensive evaluation model for life support equipment of hospital,so as to improve quality of management for equipment.Methods:Based on the operating status of life support equipment in Jiangmen Maternal and Child Health Care Hospital of Guangdong Province,a fuzzy comprehensive evaluation model was constructed,and the indicators of different levels were set.The index weights were calculated according to the Analytic Hierarchy Process(AHP),and the equipment management strategy was formulated based on the evaluated results.A total of 98 life support equipment in clinical use in our hospital from January 2023 to July 2024 were selected.In them,49 equipment were managed under the conventional management mode,and the other 49 equipment were managed under the assessment system management mode of the kind of life support equipment based on fuzzy comprehensive evaluation model(model management mode)according to the random number table method.The timeliness,management effect and management efficiency of the two management modes for equipment were compared.A self-made satisfaction questionnaire was used to investigate the satisfaction scores of equipment engineers,clinicians and managers of relevant departments in usage management for equipment in the equipment usage of the two management modes.Results:The timeliness of equipment early warning,the timeliness of maintenance personnel's arrival,and the timeliness of proposing maintenance opinions were respectively(0.78±0.14)min,(5.14±2.11)min,and(10.69±3.11)min in the model management mode,all which were shorter than those in the conventional management mode,and the differences were statistically significant(t=16.697,11.857,16.117,P<0.05).The regular maintenance rate of equipment adopting the model management mode was higher than that adopting the conventional management mode,and the failure rate was lower than that adopting the conventional management mode,and the differences were statistically significant(x2=12.274,12.261,P<0.05),respectively.The maintenance time of the model management mode was shorter than that of the conventional management mode,and the operation and maintenance cost of the model management mode was lower than that of the conventional management mode,and the differences were statistically significant(t=17.451,12.707,P<0.05).The scores of management efficiencies of resource allocation,technical support,environmental guarantee and information infrastructure of the model management mode were all higher than those of the conventional management mode,and the differences were statistically significant(t=12.268,14.908,16.128,13.920,P<0.05).In usage management for equipment,the satisfaction scores of equipment engineers,clinicians and managers of relevant departments for equipment management adopting the model management mode were higher than those adopting the conventional management mode,and the differences were statistically significant(t=13.118,16.209,12.557,P<0.05).Conclusion:The assessment system of hospital for life support equipment based on the fuzzy comprehensive evaluation model can enhance the quality of management and operation for equipment,and improve the service level of equipment,and increase the operational efficiency of equipment.

Objective To explore the method for grading the degree of uterine adhesion in a rat model.Methods A rat model of uterine adhesion was established using the double-injury method.Paraffin sections were observed using HE staining and Masson staining to compare morphological changes in the uterus,endometrial thickness,gland and vessel counts,uterine cavity area,and adhesion severity.Rat sections were classified into three grades based on uterine cavity area for comparative analysis.Results The average uterine cavity area and uterine cavity area/endometrial layer area were smaller in rats in the model group compared with the blank group(P＜0.01).The uterine cavity area/endometrial layer area ratio was categorized into grades Ⅰ,Ⅱ,and Ⅲ,with a significant difference among the grades(P＜0.05,P＜0.01).Conclusions The uterine cavity area/endometrial layer area ratio may reflect the grading difference in the degree of uterine adhesion in rats with uterine adhesions.This ratio may thus be used as a grading-evaluation criterion in the rat model of uterine adhesion,with implications for diagnostic grading in this model.

Objective A comparison of different routes for the administration of clodronate disodium liposomes to determine the most effective method of rat endometrial macrophage clearance.Methods Female 8-week-old SD rats were randomly divided into a unilateral control group(injected with 100 μL PBS liposomes into the left uterine cavity),unilateral clearance group(injected with 100 μL clodronate liposomes into the right uterine cavity),bilateral control group(injected with 100 μL PBS liposomes into the bilateral intrauterine),bilateral clearance group(injected with 100 μL clodronate liposomes into the bilateral intrauterine),whole-body control group(injected with 500 μL PBS liposomes into the caudal vein),and whole-body clearance group(injected with 500 μL clodronate liposomes into the caudal vein).Hematoxylin and eosin staining was used to observe the morphology and structures of uterine and ovarian tissues,immunohistochemistry was used to observe the presence of macrophages in uterine and ovarian tissues,and flow cytometry was used to detect changes to macrophage cell counts in uterine and ovarian tissues.Results There were no significant differences in the structures or morphology of the uterus and ovary among the groups.Immunohistochemical staining showed that,compared to the control group,the unilateral and bilateral uterine clearance groups'population of terine macrophages was significantly decreased(P＜0.001),but there was no difference in the accumulation of macrophages in the ovary(P＞0.05).The number of macrophages in both uterine and ovarian tissues decreased in the whole-body clearance group(P＜0.01,P＜0.01).Compared with the unilateral and bilateral clearance groups,the whole-body clearance group had more macrophages in the ovarian tissues(P＜0.05).Flow cytometry showed that,compared with the control group,each clearance group's percentages of macrophages in the uterine tissue were significantly reduced(P＜0.001,P＜0.001,P＜0.05).Compared to the whole-body clearance group,the unilateral and bilateral clearance groups'endometrial macrophages had superior clearance activity(P＜0.05,P＜0.05).In addition,the number of macrophages in ovarian tissue decreased in all clearance groups compared to the control group.The decrease in macrophage number was most pronounced in the whole-body clearance group(P＜0.05),and there was no significant difference in numbers between the unilateral and bilateral clearance groups and the control group(P＞0.05).Conclusions Local injection of clodronate liposomes was more effective than caudal injection for clearing uterine macrophages,and the impact on ovarian macrophages was largely avoided.Thus local clodronate liposome injection is an improved method for establishing a local uterine macrophage clearance model.

OBJECTIVETo review and collect the study achievements and the effect mechanism of acupuncture in the treatment of premature ovarian failure (POF) in recent 20 years so as to provide more references for the clinical treatment of POF with acupuncture.

METHODSThrough retrieving PubMed, CNKI and VIP, the literature on acupuncture for POF was collected from January 1, 1998 through March 31, 2017 regarding the rule of acupoint selection and the therapeutic method. The potential effect mechanism was explored.

RESULTSFinally, 26 papers on the clinical treatment for POF with acupuncture and 5 ones on the laboratory mechanism were obtained. The differentiated syndromes and the top 3 acupoints for the treatment of POF included syndrome [Taixi (KI 3), Sanyinjiao (SP 6) and Guanyuan (CV 4)], syndrome [Sanyinjiao (SP 6), Zusanli (ST 36) and Ciliao (BL 32)], syndrome [Taichong (LR 3), Shenting (GV 24), Guanyuan (CV 4)], the mixed syndrome of and [Sanyinjiao (SP 6), Ganshu (BL 18) and Shenshu (BL 23)], the mixed syndrome of and [Pishu (BL 20), Sanyinjiao (SP 6) and Zusanli (ST 36)] and the dysfunction of the thoroughfare vessel and the conception vessel [Guanyuan (CV 4), Zigong (EX-CA 1) and Huangshu (KI 16)]. The top 5 acupoints of the 14 meridians were Guanyuan (CV 4), Shenshu (BL 23), Sanyinjiao (SP 6), Zhongji (CV 3), Pishu (BL 20), Taixi (KI 3) and Ganshu (BL 18). The local extraordinary points were dominant. According to the use frequency of the acupoints, the first top 5 meridians were the bladder meridian of foot-, the governor vessel, the conception vessel, the spleen meridian of foot- and the kidney meridian of foot-. The most acupoints were distributed in the chest, the abdomen, the lumber region and the lower limbs. Many therapeutic methods were used, such as acupuncture with filiform needle, electroacupuncture, moxibustion and the acupoint thread-embedding therapy. The effect mechanisms possibly referred to the recovery of the sexual level through regulating the hypothalamus-pituitary gland-ovarian axle (HPOA) function, the improvement of the histological morphology of the uterine, the improvement of body immunity through affecting the nerve-endocrine-immune regulation system as well as the regulation of the genetic and protein expressions of the signal pathway relevant with POF.

CONCLUSIONEven though acupuncture has achieved the therapeutic effects in the clinical treatment of POF, the research on the effect mechanism is still limited. The exploration of acupuncture for POF in terms of mechanism may guide the clinical practice. In the future study, the clinical pathway should be specified and the effect mechanism be explored through the rigorous laboratory design and more objective and rational evaluation system.
