RESUMEN
ObjectiveTo discuss the impact of Buzhong Yiqitang on lipid metabolism in skeletal muscle of exercise-induced fatigue （EIF） mice through adiponectin receptor 1 （Adipor1）/adenosine 5'-monophosphate（AMP）-activated protein kinase （AMPK）/peroxisome proliferator-activated receptor gamma coactivator-1α （PGC-1α）. MethodC57BL6J mice were randomly divided into the control group， model group， low， middle， and high dose groups of Buzhong Yiqitang， and vitamin C group. No intervention was given to the control group， while the other groups were subjected to exhaustive swimming training to establish the EIF model. One hour before exhaustion， 0.2 mL distilled water was given to the control group and the model group， while the mice in the low， middle， and high dose groups of Buzhong Yiqitang were given intragastrically Buzhong Yiqitang of 4.1， 8.2， and 16.4 g·kg-1， respectively， and the vitamin C group was given vitamin C of 0.04 g·kg-1 via gavage for a duration of six weeks. After six weeks of the experiment， the growth rate of body weight， organ index， and exhaustive swimming time were calculated. Enzyme colorimetry was utilized to detect the levels of blood urea nitrogen （BUN）， creatine kinase acid （CK）， lactate dehydrogenase acid （LDH）， and lactic acid （LD）. The pathological changes of skeletal muscle were observed using hematoxylin -eosin （HE） staining， while the ultrastructure of skeletal muscle was observed with transmission electron microscope （TEM）. The contents of free fatty acids （NEFA） and triglyceride acid （TG） in serum were also examined by microplate method. The protein expressions of Adipor1， p-AMPK/AMPK， PGC-1α， and HK2 in the skeletal muscle were measured by Western blot. ResultCompared with those of the control group， the growth rate of body weight and thymus index of the model group were decreased， and the serum levels of BUN， CK， LD， and LDH were increased （P<0.01）. The contents of NEFA and TG were decreased （P<0.01）， and the protein expression of Adipor1， p-AMPK/AMPK， PGC-1 α， and HK2 in the skeletal muscle decreased （P<0.05， P<0.01）. Compared with those in the model group， the growth rate of body weight， thymus index， and exhaustive swimming time were significantly increased （P<0.01）， and the levels of BUN， CK， LD， and LDH dropped in the high dose group of Buzhong Yiqitang （P<0.01）. The levels of NEFA and TG were greatly improved （P<0.01）. The protein expressions of Adipor1， p-AMPK/AMPK， PGC-1α， and HK2 in the skeletal muscle were significantly increased （P<0.05， P<0.01）. Compared with those in the model group， the thymus index and exhaustive swimming time were significantly increased in the vitamin C group， and the levels of BUN， CK， and LD dropped （P<0.05， P<0.01）. The levels of NEFA and TG were improved significantly （P<0.01）， and the protein expression of Adipor1 in skeletal muscle was increased greatly （P<0.01）. ConclusionBuzhong Yiqitang can delay the development of EIF， which may be connected with the regulation of the Adipor1/AMPK/PGC-1α signaling pathway and the improvement of the utilization rate of skeletal muscle to fat.
RESUMEN
Objective:To investigate the survival rate and clinical failure reasons of onlay and occlusal veneer restorations retrospectively,and to put forward valuable suggestions for the selection of clinical in-dications.Methods:A total of 102 patients and 124 teeth treated by one of the authors from 2016 to 2019 were subjected to CAD/CAM lithium silicate reinforced glass-ceramic onlay or veneer restorations of premolars and molars,including 43 teeth with pulp vitality,81 endodontic treated teeth,and occlusal thickness of restoration was 1.5 mm.After four years of restoration,retrospective surveys were conducted to record the survival rate of restorations,the causes of restoration failure,and patient satisfaction rates,and the survival rate of restorations between vital teeth and endodontic treated teeth and among restored teeth was statistically analyzed by Chi-square test.Results:The survival rates of restorations on vital teeth and endodontic treated teeth were 95.5％and 90.0％,respectively,the average survival rate was 90.2％.The survival rates of vital teeth were higher than those of endodontic treated teeth without statis-tical difference.There was also no statistically significant difference among the tooth locations.The cau-ses of failure included the cracking of the restoration,the loss of the restoration,the fracture of the abut-ment teeth,secondary caries below the adjacent contact point,and food impaction caused by the loose-ning of the adjacent contact point.The overall patient satisfaction rate was 91.5％.Conclusion:The 4-year survival rate of glass-ceramic onlays and occlusal veneers is lower than that of the full crown restora-tion,and there are more complications than that of the single-crown restorations.The design of the resto-ration should be carefully selected based on the vitality of the abutment tooth and the remaining amount of tooth tissue.When there is too little tooth structure left,a post and crown should be selected for restora-tion.Adequate strength and thickness of the restoration should be ensured to prevent food impaction.Due to the small amount of abutment tooth preparation,it has the advantages of less stimulation of the pulp and periodontal tissue,and can be recommended as a trial restoration.
RESUMEN
Objective To explore the eradication rate of human papillomavirus(HPV)and gestational outcome of patients with high-grade squamous intraepithelial disease of the cervix(HSIL)after loop electrosurgical excision procedure(LEEP)by transvaginal dissection of the vesicorectal form the cervix.Methods A total of 53 patients treated with LEEP by transvaginal dissection of the vesicorectal form the cervix in Obstetrics and Gynecology Hospital,Fudan University from Jan to Dec,2019 were investigated.Clinical information of cervical cytological examination,HPV test and cervical biopsy under colposcopy were followed up for 6,12 and 24 months post-LEEP were collected.HPV infection in these 53 patients were compared before and after LEEP surgery.The rate of successful fertility of the cohort,the HPV conversion rate of patients with hysterectomy and LEEP done were compared.The association between the pathological type and positive surgical margin and the association between HPV infection type and positive surgical margin were analyzed.Results HPV infection rate of was 94.3%(50/53)and the proportion of HPV16 and/or 18 infection was 75.5%(40/53).Mono-HPV infection rate(69.8%,37/53)was significantly higher than mixed HPV infection rate(22.7%,13/53).Thirty-eight patients(71.7%)were found with positive surgical margin in previous LEEP operation.Fifteen patients had recurrence(28.3%)and 40 patients(75.5%)successfully delivered baby after surgery.Postoperative pathology was mainly HSIL,accounting for 66%(30/53),and 28.3%patients(15/53)had no pathological change.Forty cases had satisfying fertility-conservative operation outcome with negative surgical margin,and 38 patients eradicated HPV infection after LEEP,which took up 95%of patients with satisfying fertility-conservative operation.There was no significant difference of positive resection margin rate in between groups of HPV16/18 infection and other types.Five cases had successful delivery(12.5%,5/40)with 1 case of vaginal delivery and 4 cases of cesarean section.Among these 5 cases,3 cases undertook preventive cervical cerclage,with 1 case of vaginal delivery and 2 cases of cesarean sections.Conclusion HPV eradication rate and surgical outcome could be significantly improved by LEEP with transvaginal dissection of the vesicorectal from the cervix,which satisfied the fertility preservation of females at reproductive age.
RESUMEN
Objective To explore the correlations of evaluations of right heart function parameters in patients with Ebstein anomaly(EA)using echocardiography and cardiac MRI.Methods Data of transthoracic echocardiography and cardiac MRI in 32 patients with EA confirmed by operation were retrospectively analyzed.The correlations of cardiac cavity size,right ventricular function and strain parameters obtained using echocardiography and the functional right ventricular(fRV)ejection fraction(EF)measured using MRI were explored.Results MRI fRV-EF in 32 cases of EA was(23.20± 7.61)％.Among echocardiographic parameters in 32 cases of EA,fractional area change(FAC)of fRV(r=0.347,P=0.015)was slightly,while global longitudinal strain(GLS)of fRV(r=0.801,P＜0.001)was highly positively correlated with MRI fRV-EF,respectively,whereas atrialized right ventricle(aRV)area/fRV area(r=-0.730,P=0.007)was highly negatively,aRV area/left ventricular area(r=-0.450,P=0.042)and right ventricular anterior-posterior diameter(r=-0.650,P=0.022)were both moderately negatively correlated with MRI fRV-EF.Both the left ventricular eccentricity index(r=-0.347,P=0.049)and Glasgow outcome scale extended(r=-0.336,P=0.024)obtained with echocardiography were slightly negatively correlated MRI fRV-EF.Conclusion Right heart function parameters in EA patients obtained with echocardiography were correlated with those of MRI fRV-GLS,among which aRV area/fRV area were highly positively correlated with MRI fRV-EF,hence having great value for evaluating right heart function in EA patients.
RESUMEN
Objective: To investigate the influence of light and heavy bite force on the mandibular movement trajectories, and the influence of bite force on virtual occlusal pre-adjustment of digital full crown. Methods: From October 2021 to March 2022, 10 postgraduate volunteers (3 males and 7 females, aged 22-26 years) were recruited from Peking University School and Hospital of Stomatology. Maxillary and mandibular digital models of the participants were obtained by intraoral scanning. Jaw relations were digitally transferred under heavy bite force and mandibular movement trajectories under light and heavy bite force were recorded by jaw motion analyser. Three mandibular markers were chosen, namely the mesial proximal contact point of the central incisor (incisal point) and the mesial buccal cusp tips of the bilateral first molars. The three-dimensional displacements of the markers under two kinds of bite force in the intercuspal position (ICP), the sagittal projection of the three-dimensional displacements in the protrusive edge-to-edge position, and the coronal projection of the three-dimensional displacements in the lateral edge-to-edge position of upper and lower posterior teeth were measured. Single-sample t-test was used to compare the three-dimensional displacements and the corresponding sagittal projection and coronal projection with 0, respectively. The left maxillary central incisor and left mandibular first molar were virtually prepared by the reverse engineering software. Then dental design software was used to design digital full crown using the copy method. The mandibular movement trajectories under light and heavy bite force were separately used to guide virtual occlusal pre-adjustment. The three-dimensional deviations (mean deviations and root mean square) between the lingual surface of the left maxillary central incisor or the occlusal surface of the left mandibular first molar and that of the natural tooth before preparation were calculated (light bite force group and heavy bite force group), and the differences between the two groups were compared by the paired t-test. Results: Under the two kinds of bite force, the three-dimensional displacements of the markers in the ICP were (0.217±0.135), (0.210±0.133) and (0.237±0.101) mm, respectively; the sagittal projection of the three-dimensional displacements of the markers in the protrusive edge-to-edge position were (0.204±0.133), (0.288±0.148) and (0.292±0.136) mm, respectively; the coronal projection of the three-dimensional displacements of the mesial buccal cusp tips of the bilateral first molars in the lateral edge-to-edge position were (0.254±0.140) and (0.295±0.190) mm, respectively. The differences between the above displacements and 0 were statistically significant (P<0.05). The results of occlusal pre-adjustment showed that the mean deviations of the lingual surface of the left maxillary central incisor in the light and heavy bite force groups were (0.215±0.036) and (0.195±0.041) mm (t=3.95, P=0.004), respectively. The mean deviations of the occlusal surface of the left mandibular first molar were (0.144±0.084) and (0.100±0.096) mm (t=0.84, P=0.036), respectively. Conclusions: Both the light and heavy bite force have an influence on the mandibular movement trajectories. Virtual occlusal pre-adjustment of prostheses with mandibular movement trajectories under heavy bite force can obtain morphology of lingual or occlusal surfaces closer to the natural teeth before preparation.

Body mass index (BMI) has been increasing globally in recent decades. Previous studies reported that BMI was associated with sex hormone levels, but the results were generated via linear regression or logistic regression, which would lose part of information. Quantile regression analysis can maximize the use of variable information. Our study compared the associations among different regression models. The participants were recruited from the Center of Reproductive Medicine, The First Hospital of Jilin University (Changchun, China) between June 2018 and June 2019. We used linear, logistic, and quantile regression models to calculate the associations between sex hormone levels and BMI. In total, 448 men were included in this study. The average BMI was 25.7 (standard deviation [s.d.]: 3.7) kg m-2; 29.7% (n = 133) of the participants were normal weight, 45.3% (n = 203) of the participants were overweight, and 23.4% (n = 105) of the participants were obese. The levels of testosterone and estradiol significantly differed among BMI groups (all P < 0.05). In linear regression and logistic regression, BMI was associated with testosterone and estradiol levels (both P < 0.05). In quantile regression, BMI was negatively associated with testosterone levels in all quantiles after adjustment for age (all P < 0.05). BMI was positively associated with estradiol levels in most quantiles (≤80th) after adjustment for age (all P < 0.05). Our study suggested that BMI was one of the influencing factors of testosterone and estradiol. Of note, the quantile regression showed that BMI was associated with estradiol only up to the 80th percentile of estradiol.

Objective: To investigate the effects of two-step retraction and en-masse retraction on tooth movement pattern of anterior teeth and posterior anchorage with clear aligners using three-dimensional finite element analysis. Methods: A finite element model of maxillary first premolar extraction case undergoing clear aligner treatment was established based on maxillofacial cone-beam CT data of a 24-year-old adult male with individual normal occlusion, who visited Department of Oral Surgery, Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine for impacted mandibular third molar in June, 2022. The initial tooth displacement of five anterior retraction protocols (two-step with canine retraction, two-step with incisor bodily retraction, two-step with incisor retraction-overtreatment, en-masse bodily retraction, and en-masse retraction-overtreatment) were evaluated. Results: Two step with canine retraction caused distal tipping of the canine and labial tipping of the incisors (0.18° for central incisor and 0.13° for lateral incisor). Two step with incisor retraction caused mesial tipping of the canine. In two step with bodily retraction protocol, uncontrolled lingual tipping was found in central incisor (0.29°) and lateral incisor (0.32°). In two-step with incisor retraction-overtreatment protocol, the movement pattern of the incisors didn't change, but the inclinations reduced to 0.21° and 0.18°. En-masse retraction caused distal tipping of the canine. In en-masse bodily retraction protocol, uncontrolled lingual tipping was also found in central incisor (0.19°) and lateral incisor (0.27°). In en-masse retraction-overtreatment protocol, the central incisor showed controlled lingual tipping (0.02°) and the lateral incisor showed palatal root movement (0.03° labial inclination). Posterior teeth exhibited mesial tipping in all five protocols. Conclusion: En-masse retraction with incisor overtreatment was beneficial to incisor torque control in clear aligner treatment.
RESUMEN
With the rapid development of information technology and the change in military education policy in the new era, online teaching has gradually become one of the main approaches to implement the clinical medical education in military teaching hospitals. In this study, the online teaching was performed mainly by pre-recorded teaching, supplemented by online live teaching. Massive open online courses (MOOCs) and the seminar-style teaching were advocated to be used in advanced disciplines. The quality of online teaching was guaranteed through infrastructure provision, teacher arrangement, teaching preparation, teaching interactivity, after-class test, teaching evaluation, supervision, and summary of teaching, which ultimately achieved a good effect. The results of the two-way questionnaires of 26 teachers and 129 students showed that 23.26% (30/129) of students and 65.38% (17/26) of teachers believed that students' learning ability was insufficient. 34.88% (45/129) of students and 23.08% (6/26) of teachers thought that the existing technology could not meet the requirements of online teaching. 55.04% (71/129) of students and 69.23% (18/26) of teachers held the view that the effect of online teaching was inferior to face-to-face teaching. 28.68% (37/129) of students and 57.69% (15/26) of faculty asked for the return of face-to-face education. Therefore, it is necessary to strengthen the construction of smart classroom platforms, establish a well-developed online teaching quality evaluation system, and integrate various innovative teaching modes with the online teaching. In these ways, it is expected to optimize the online teaching of clinical medicine and achieve the goal of online teaching.
RESUMEN
Objective:To investigate the effect of microbubbles combined with gentamicin on the clearance of bacterial biofilms and the healing of diabetic foot ulcers under low-frequency ultrasound.Methods:From July 2021 to June 2022, 27 patients with chronic diabetic foot ulcers complicated with infection were prospectively selected from the Trauma Center of the Second Affiliated Hospital of Chongqing Medical University. The patients were divided into low-frequency ultrasound + microbubbles + gentamicin ointment group, low-frequency ultrasound + microbubbles group, and gentamicin ointment group by using a random number table, with 9 patients in each group. The three groups were all treated with simple debridement by the same surgeon.Afterward, in the low-frequency ultrasound+ microbubbles+ gentamicin ointment group, the wounds covered by 4% microbubble suspension were firstly irradiated with low-intensity focused ultrasound for 5 min, and then evenly applied with gentamicin ointment. In the low-frequency ultrasound + microbubbles group, the wounds covered by 4% microbubble suspension were irradiated with low-intensity focused ultrasound for 5 min. The gentamicin ointment group was treated with gentamicin ointment evenly. The treatment lasted for 2 weeks, and secretions and tissue specimens were collected during and 2 weeks after the treatment, respectively. The general indexes of wound surface (including ulcer depth score, secretion exudation score, fresh granulation tissue growth score, and total index score), ulcer area, ulcer healing rate, as well as negative rate of secretion culture were compared among the three groups after treatment. Additionally, the structural changes in bacterial biofilms under a scanning electron microscope and colony count under a laser confocal scanning microscope were compared among the three groups after treatment.Results:No significant differences were found in the general datas among the three groups (all P>0.05). After treatment for 2 weeks, the overall general indexes showed statistically and significant differences among the three groups (all P<0.05). Each index score in the low-frequency ultrasound + microbubbles + gentamicin ointment group was lower than that in the low-frequency ultrasound + microbubbles group and the gentamicin ointment group (all P<0.05). There were no significant differences in overall ulcer area among the three groups ( P>0.05). The overall ulcer healing rate presented significant differences among the three groups ( P<0.05). The healing rate in the low-frequency ultrasound + microbubbles + gentamicin ointment group was higher than that in the low-frequency ultrasound + microbubbles group and the gentamicin ointment group (all P<0.05). The overall negative rates of secretion culture among the three groups were significantly different ( P<0.05), the negative rate in the low-frequency ultrasound + microbubbles + gentamicin ointment group was higher than that in the low-frequency ultrasound + microbubbles group and the gentamicin ointment group (all P<0.05). Scanning electron microscopy confirmed bacterial biofilm infection in the three groups before treatment. After treatment for 2 weeks, the biofilm formation in the low-frequency ultrasound + microbubbles + gentamicin ointment group reduced significantly, while the low-frequency ultrasound + microbubbles group and the gentamicin ointment group had little change compared with that before treatment. Significant differences were detected in total colony count among the three groups under the confocal microscope ( P<0.05). The colony count in the low-frequency ultrasound + microbubbles + gentamicin ointment group was lower than that in the low-frequency ultrasound + microbubbles group and the gentamicin ointment group (both P<0.05). Conclusions:Ultrasound microbubbles combined with gentamicin can clear bacterial biofilms and promote the healing of diabetic foot ulcers.

Two years and 10 months of follow-up were given to the benign patient and the malignant patient after surgery, and both patients were in good general condition with no tumor recurrence or metastasis.
RESUMEN
In order to further promote the reform of medical service price and strengthen the macro management of medical service price, the author constructed a calculation method for price adjustment space of medical service. This study was centered on two parameters of the historical base and the growth coefficient, to calculate the total amountof price adjustment. The historical base used the total revenue of medical services in the region from the previous year, and the growth coefficient was measured by two methods, the comprehensive indicator method and the consumer price index (CPI) reference method.Taking Suzhou, a national pilot city, as an example, the historical base in 2022 was 18 754 million yuan. By using the comprehensive indicator method, the annual growth coefficient was calculated to be 2.38%, and adjustment space of medical service price was 446.35 million yuan; According to the CPI reference method, the growth coefficient of Suzhou was 2.10%, and adjustment space of medical service price was 393.83 million yuan.The two methods for calculating the total amount each have their own advantages and disadvantages, and need to be further optimized and improved by drawing on the practical experience of reform in each pilot city.
RESUMEN
Objective:To design a set of evaluation index system for the medical service price reform mechanism, so as to provide reference for the evaluation of deepening the medical service price reform mechanism.Methods:On the basis of searching literature of medical service prices reformfrom August 2021 to March 2023, policy logic analysis and expert consultation were used to construct evaluation indexes for the medical service price reform mechanism, set evaluation index thresholds, and assign scores to index thresholds in different grades.Results:The evaluationindex system of medical service price reform mechanism included 5 level-1 indexes, 12 level-2 indexes and 35 level-3 indexes. After scoring, the scores of 5 level-1 indexes were 12, 24, 35, 21, and 8, respectively.Based on the percentile scoring method, the evaluation criteria were categorized into five grades: premium, excellent, good, average and failure.Conclusions:This study constructed a set of evaluation index system for the mechanism of medical service price reform, which had strong scientific and operability. However, due to the fact that medical service price reform in the new era is still in its initial stage, the index system need to be further optimized drawing on the practical experience of reforms in pilot cities.
RESUMEN
[Objective]To investigate the relationship between platelet activation and traditional Chinese medicine(TCM)syndrome distribution in patients with diabetic peripheral neuropathy(DPN).[Methods]A total of 188 DPN patients admitted to our hospital from February 2020 to December 2022 were collected.The TCM syndrome type usesd the index cluster analysis to draw the cluster diagram.The correspondence between TCM syndrome type and lesion degree was analyzed by simple correspondence analysis,and shown on the two-dimensional plan.It compared the general clinical data,platelet parameters and platelet activation of different TCM syndrome types,so as to explore the relationship between platelet activation and the distribution of TCM syndrome types.[Results]The syndrome types summarized in different positions of the cluster map were different.Among them,D-point interception could be divided into five syndrome types:Qi deficiency syndrome,Yin deficiency syndrome,Yang deficiency syndrome,stagnation of blood stasis syndrome and phlegm-dampness blocking collaterals syndrome.Among the 188 DPN patients,phlegm-dampness blocking collaterals syndrome was found in 18 cases(9.57％),stagnation of blood stasis syndrome in 53 cases(28.19％),Yang deficiency syndrome in 28 cases(14.89％),Yin deficiency syndrome in 39 cases(20.74％),and Qi deficiency syndrome in 50 cases(26.60％).The grade of DPN lesion was grade Ⅰ in 56 cases(29.79％),grade Ⅱ in 76 cases(40.43％),and grade Ⅲ in 56 cases(29.79％).The syndrome of phlegm-dampness blocking collaterals and stagnation of blood stasis in the middle of the two-dimensional projection map did not deviate to a certain grade of DPN lesion degree;Yang deficiency syndrome inclined to grade Ⅲ,Yin deficiency syndrome to grade Ⅱ,and Qi deficiency syndrome to grade Ⅰ.Compared with Qi deficiency syndrome,platelets(PLT),mean platelet volume(MPV),platelet distribution width(PDW),granular membrane protein-140(GMP-140),platelet activating factor(PAF)and E26 transformation specific-l(ETS-l)in patients with Yin deficiency syndrome and Yang deficiency syndrome were significantly higher(P＜0.05),and PLT,MPV,PDW,GMP-140,PAF and ETS-1 in patients with Yang deficiency syndrome were higher than those of Yin deficiency syndrome(P＜0.05).[Conclusion]DPN can be routinely divided into five basic syndrome types:Qi deficiency,Yin deficiency,Yang deficiency,stagnation of blood stasis and phlegm-dampness blocking collaterals.With the development of DPN,TCM syndromes are transformed from Qi deficiency to Yin deficiency to Yang deficiency,while blood stasis and phlegm-dampness blocking collaterals are accompanied by various stages of DPN patients.In the progress of DPN,platelet activation may be involved in the transformation of TCM syndrome types.
RESUMEN
Objective: To compare the efficacy of intravascular ultrasound (IVUS) and coronary angiography guided drug eluting stent (DES) implantation for the treatment of left main coronary artery (LMCA) lesions. Methods: Randomized controlled trials (RCT) and observational studies, which compared IVUS with coronary angiography guided DES implantation for the treatment of LMCA lesions published before August 2021 were searched in PubMed, Embase and Cochrane Library databases. Baseline data, interventional procedures and endpoint events of each study were collected. The primary endpoint was major cardiovascular adverse events (MACE), and the secondary endpoints were all-cause death, cardiac death, myocardial infarction (MI), target lesion revascularization (TLR) and target vessel revascularization (TVR). The Newcastle-Ottawa Scale (NOS) and the Cochrane Collaboration Risk of Bias tool were used to evaluate the quality of the included studies. Results: Nine studies were included, including 3 RCT and 6 observational studies, with a total of 5 527 cases of LMCA. All the 6 observational studies had NOS scores≥6, and the 3 RCT had a low risk of overall bias. The results of meta-analysis showed that compared with coronary angiography guided group, MACE rate (OR=0.55, 95%CI 0.47-0.66, P<0.001), all-cause death (OR=0.56, 95%CI 0.43-0.74, P<0.001), cardiac death (OR=0.43, 95%CI 0.30-0.61, P<0.001), MI (OR=0.64, 95%CI 0.52-0.79, P<0.001), TLR (OR=0.49, 95%CI 0.28-0.86, P=0.013) and TVR (OR=0.77, 95%CI 0.60-0.98, P=0.037) were all significantly lower in the IVUS guided group. Conclusions: Compared with angiography guided, IVUS guided PCI with DES implantation in LMCA lesions could significantly reduce the risk of MACE, death, MI, TLR and TVR. IVUS is thus superior to coronary angiography for guiding PCI treatment among patients with LMCA.

OBJECTIVES@#Pregnancy stress is the psychological confusion or threat caused by various stress events and adverse factors during pregnancy. Pregnant women exposed to many stressors, they will be easy to produce bad mood and prenatal depression if they cannot adapt to their own changes. Prenatal depression is one of the major global public health problems, with a higher incidence in developing countries and a negative impact on the health of pregnant women and fetus. Resilience refers to pregnant women using their own positive psychological capital, can self-emotional adjustment and improve their ability to adapt to the response state. A better level of resilience can enable pregnant women to face various negative and adaptive problems positively. This study aims to investigate the relationship between pregnancy stress, resilience and prenatal depression through a mental health survey of pregnant women.@*METHODS@#A total of 750 pregnant women in a Grade A tertiary hospital in Urumqi were investigated by self-designed demographic questionnaire, Pregnancy Pressure Scale (PPS) and Patient Health Questionnaire-9 (PHQ-9), Connor-Davidson Resilience Scale (CD-RISC), and the levels of stress during pregnancy, prenatal depression and resilience were analyzed. Pearson correlation analysis was used to explore the correlation between the three. Bootstrap mediation effect test was used to test the mediation effect relationship among the three. If the mediation effect was confirmed, AMOS software was used to establish the mediation effect structural equation model to analyze the mediation effect among the three.@*RESULTS@#Among 750 respondents, 709 (94.53%) had mild or above pregnancy pressure, 459 (61.20%) had mild or above depressive symptoms and 241 (32.13%) had a good or above level of resilience. Pearson correlation analysis showed that prenatal depression was significantly positively correlated with pregnancy stress (P<0.01), prenatal depression and pregnancy stress were significantly negatively correlated with resilience (all P<0.01). Mediation effect test analysis showed that all the pathways were statistically significant (P<0.01). Mediation effect of resilience between pregnancy stress and prenatal depression was significantly found (95% CI 0.022-0.068, P<0.001). Pregnancy pressure negatively affected resilience (β=-0.38, P<0.01), and resilience negatively affected prenatal depression (β=-0.10, P<0.01). The mediation effect of resilience was 6.5%.@*CONCLUSIONS@#Pregnant women's pregnancy pressure, resilience and prenatal depression are significantly correlated, and the mediation variable resilience plays a partial mediating role in the impact of pregnancy pressure on prenatal depression. Pregnant women can reduce the incidence of prenatal depression and promote their physical and mental health by exercising their resilience.

Objective:To explore the application efficacy of ultrasound-guided dorsal scapular nerve block in treating postoperative pain after shoulder arthroscopic surgery.Methods:A total of 60 patients underwent shoulder arthroscopic surgery who admitted to hospital were selected,and all patients were divided into dorsal scapular nerve block group,intermuscular groove brachial plexus block group and oral analgesic therapy group according to the treatment methods for postoperative pain,with 20 cases in each group.The visual analogue score(VAS)of pain,the number of effective compressing analgesic pump within 24 hours after surgery and the number of cases of using pethidine to remedy analgesia,the degree of numbness in the affected limb at the time of leaving the anesthesia recovery room and 6 hours after surgery,adverse reactions after anesthesia resuscitation,and satisfaction of patient were compared among the three groups.Results:The differences of VAS scores of three groups at the time of extubation,the 3rd h,6th h,12th h and 24th h after surgery between resting state and action state were not significant(tat the time of extubation=1.04,t=1.11,t3rd h=0.97,t=1.03,t6th h=0.86,t=0.93,t12th h=1.01,t=0.81,t24th h=1.17,t=1.01,P>0.05),respectively.Within postoperative 24h,there were not significant differences between the number of effective compressing analgesic pump and the rate of remedy analgesia in dorsal scapular nerve block group(x2=1.347,x2=1.556,P>0.05),respectively.The degree of numbness in the affected limb at the time of leaving the anesthesia recovery room and the 6th hours after surgery in dorsal scapular nerve block group was significantly better than that in intermuscular groove brachial plexus block group and oral analgesic therapy group(x2=5.316,x2=5.452,P<0.05),respectively.The rate of upper limb numbness and weakness and the rate of difficulty breathing at 1st d after surgery in dorsal scapular nerve block group was significantly better than that in intermuscular groove brachial plexus block group and oral analgesic therapy group(x2=7.631,x2=6.973,P<0.05),respectively.The probability of the satisfaction of patients for postoperative analgesic effect in dorsal scapular nerve block group was significantly better than that in intermuscular groove brachial plexus block group and oral analgesic therapy group(x2=6.592,x2=6.638,P<0.05),respectively.Conclusion:Ultrasound-guided dorsal scapular nerve block has favorable analgesic effect after surgery,which can improve the degree of the numbness of the affected limb and the adverse reactions after anesthesia resuscitation for patients.It is a safe and effective treatment method for pain.
RESUMEN
Objective:To explore the therapeutic characteristics of population with gout achieving treat-to-target (T2T) indicators through real-world research and evaluate their safety.Methods:A total of 3 287 patients diagnosed with gout by rheumatologists in 21 first-class tertiary hospitals in 10 provinces, municipalities, and autonomous regions in China from January 2015 to December 2021 were included in this polycentric cross-sectional study. The database included patients′ general information, disease characteristics, and clinical application of traditional Chinese and Western medicine treatment measures. SPSS and Excel software were used for data analysis. Frequency analysis, cluster analysis, and factor analysis were used to summarize the characteristics and rules of treatment measures for patients with gout who achieved the target after treatment. The occurrence of adverse events (AE) was recorded during treatment.Results:After treatment, 691 visits (7%) achieved the serum urate (SUA) target, and the most frequent use of urate-lowering therapy (ULT) was febuxostat, followed by benzbromarone. The most common treatment options were following: GroupⅠ: traditional Chinese medicine (TCM) decoction-TCM external treatment-physical exercise-proprietary Chinese medicine; GroupⅡ: ferulic acid-nonsteroidal anti-inflammatory drugs (NSAIDs); Group Ⅲ: allopurinol-sodium bicarbonate-benzbromarone; Group Ⅳ: glucocorticoid-colchicine; Group Ⅴ: febuxostat. A total of 5 898 visits (60%) chieved manifestations of joint pain VAS scores target, and the most frequently used drug to control joint symptoms was NSAIDs. The frequency of use of drugs to control joint symptoms were 2 118 times (usage rate reached 35.9%), while the frequency of ULT were 2 504 times (usage rate reached 42.5%), which was higher than the joint symptom control drug. The most common treatment options were following: Group Ⅰ: proprietary Chinese medicine-TCM decoction-TCM external treatment-physical exercise; Group Ⅱ: NSAIDs-colchicine hormones; Group Ⅲ: allopurinol, Group Ⅳ: benzbromarone; Group Ⅴ: febuxostat. A total of 59 adverse events occurred during treatment.Conclusion:The proportions of gout patients who reach target serum urate level & good control of joint symptoms are both very low, and ULT and anti-inflammatory prescription patterns are very different from international guidelines, so it is necessary to strengthen the standardized management of gout patients. At the same time, life intervention measures account for a certain proportion of the treatment plans for the T2T population, and further exploration is needed.
RESUMEN
Objective@#This study aimed to investigate whether cytokine profiles and virological markers might add value in monitoring the effects of peginterferon (PEG-IFN) therapy for hepatitis B e-antigen (HBeAg) positive chronic hepatitis B (CHB).@*Methods@#HBeAg positive patients with CHB were treated with PEG-IFN for 48 weeks. Clinical biochemical, and HBV serological indexes, as well as cytokines, were detected at baseline and every 12 weeks.@*Results@#A total of 116 patients with CHB were enrolled in this study; 100 patients completed the 48-week treatment and follow-up, of whom 38 achieved serum HBeAg disappearance, 25 achieved HBeAg seroconversion, 37 showed HBsAg decreases ≥ 1 log 10 IU/mL, 9 showed HBsAg disappearance, and 8 became HBsAb positive. The cytokine levels at baseline and during treatment were similar between the HBeAg disappearance group and non-disappearance group. The disappearance of HBeAg was independently associated with HBeAg levels at weeks 12 and 24, and with the HBeAg decline at week 24 ( P < 0.05). The HBsAg response was independently associated with HBsAg, the HBsAg decline, HBeAg, the HBeAg decline at week 12, and HBsAg at week 24 ( P< 0.05).@*Conclusion@#There was no significant correlation between the response to interferon (IFN) and cytokines during PEG-IFN treatment. The changes in virological markers predicted the response to IFN after 48 weeks.

OBJECTIVES@#To investigate the genetic polymorphism of InDel loci in SifalnDel 45plex system in the Han population in Jiangsu Province and the Mongolian population in Inner Mongolia, and to evaluate the effectiveness of the system in forensic medicine.@*METHODS@#SifaInDel 45plex system was used for genotyping in blood samples of 398 unrelated individuals from the above two populations, and allele frequencies and population genetic parameters of the two populations were calculated respectively. Eight intercontinental populations in the gnomAD database were used as reference populations. The genetic distances between the two studied populations and eight reference populations were calculated based on the allele frequencies of 27 autosomal-InDels (A-InDels). The phylogenetic trees and multidimensional scaling (MDS) analysis diagrams were constructed accordingly.@*RESULTS@#Among two studied populations, the 27 A-InDels and 16 X-InDels showed no linkage disequilibrium between each other and the allele frequency distributions were in Hardy-Weinberg equilibrium. The CDP of the 27 A-InDels in two studied populations were all higher than 0.999 999 999 9, and the CPEtrio were all less than 0.999 9. The CDP of the 16 X-InDels in Han in Jiangsu and Mongolian in Inner Mongolia female and male samples were 0.999 997 962, 0.999 998 389, and 0.999 818 940, 0.999 856 063, respectively. The CMECtrio were all less than 0.999 9. The results of population genetics showed that the Jiangsu Han nationality, Inner Mongolia Mongolian nationality and East Asian population clustered into one branch, showing closer genetic relationship. The other 7 intercontinental populations clustered into another group. And the above 3 populations displayed distant genetic relationships with the other 7 intercontinental populations.@*CONCLUSIONS@#The InDels in the SifaInDel 45plex system have good genetic polymorphism in the two studied populations, which can be used for forensic individual identification or as an effective complement for paternity identification, and to distinguish different intercontinental populations.

Objective:To observe any therapeutic effect of repeated transcranial direct current stimulation (tDCS) on rats modeling neuropathic pain and explore possible mechanisms.Methods:Forty adult male Sprague-Dawley rats were randomly divided into a normal group ( n=10), a sham operation group ( n=10), a treatment group ( n=10) and a sham treatment group ( n=10). A model of chronic constriction injury of the sciatic nerve was established in the latter two groups. Fourteen days after the modeling, the treatment group was given tDCS for 8 consecutive days, while the sham treatment group received sham stimulation, and the other 2 groups did not receive any intervention. Von Frey and hotplate tests were used to test the rats′ pain thresholds 1 day before, as well as 14 and 22 days after the surgery (i.e., 8 days after the end of the treatment). Spinal cord tissue samples were taken to detect the protein expressions of N-methyl-D-aspartic acid receptor 2B, gamma-aminobutyric acid receptor types A (GABA a-R) and B (GABA b-R) using western blotting. Results:On the 14th day after the operation the average 50% MWT and WTL values of the sham treatment and treatment groups had decreased significantly compared with the sham operation group. By the 22nd day the average 50% MWT and WTL values of the treatment group were significantly higher than those of the sham treatment group, but there was no significant change in the treatment group′s average WTL between the 21st and 22nd days. On the 22nd day after the operation the average NR2B-NMDA-R level of the sham treatment group were significantly higher than that of the sham operation group, while the average GABA a-R and GABA b-R levels were significantly lower. At the same time point the treatment group′s average NR2B-NMDA-R level had decreased significantly compared to the sham treatment group, while the average GABA a-R level had increased significantly. There was no significant difference in average GABA b-R level between the treatment group and the sham treatment group at that point. On the 22nd day there was also no significant difference in the average NR2B-NMDA-R level between the treatment group and the sham operation group. Conclusions:Repeated tDCS can effectively relieve neuropathic pain. The relief of hyperalgesia is more significant than that of mechanical allodynia. A possible mechanism may be the down-regulation of spinal NR2B-NMDA-R to normal levels and modest up-regulation of GABA a-R.
