BACKGROUND:Obsolete lateral ankle ligament injury is frequently treated by Chrisman-Snook operation.However,this operation destructs some peroneus brevis tendon,and affects the function of peroneus brevis tendon for foot valgus.OBJECTIVE:Based on previous research,to investigate the effect of allogeneic tendon for reconstruction of ankle lateral ligaments.METHODS:A total of 17 cases of ankle lateral ligament injured were selected,with a course of disease from 3 to 6 months.All lateral ligaments were reconstructed by allogeneic tendon & anchors.During the operation,a drill,4.5 rnm diameter,was used to drill a hole on the lateral ankle;one anchor was drilled into the talus at the end of anterior talofibular ligament,another one was threaded on the calcaneus;the allogeneic tendon was permeated through the hole on the lateral ankle,maintaining ankle neutral and moderate valgus position.The allogeneic tendon was sutured with the thread of the anchors.Following operation,the ankle was fixed in neutral position and slightly valgus position;wound healing,AOFAS score and stress radiograph were observed.RESULTS AND CONCLUSION:All 17 patients showed no rejection,and the wound healing well at the primary stage.At 6,12,24 after operation,all patients were followed-up.According to AOFAS criteria,function of ankle in all patients was significantly improved.No patients complained of instability of the ankle,end stress radiograph confirmed this improvement.Reconstruction of lateral ligaments of the ankle with allogeneic tendon and anchors is a practical treatment,which restores stability and function of ankle without long incision or damaging normal tendons.

Objective To investigate the expressions of DKK1,SFRP4 and Wnt1 in cervical squamous cell carcino-ma(SCC), and the clinical significance thereof. Methods There were 76 samples of cervical squamous cell carcinoma were included in SCC group and 36 benign uterine resection specimens were control group (NC). The immunohistochemical meth-od was applied to detect the expressions of DKK1,SFRP4 and Wnt1 in two groups. Results The expression of DKK1 was significantly lower in SCC group than that in NC group (P＜0.05). The expression levels of SFRP4 and Wnt1 were significant-ly higher in SCC group than those of NC group (P＜0.05). There were significant differences in the expressions of DKK1, SFRP4 and Wnt1 between samples of different clinical staging, differentiation, sizes of tumor and lymph node metastasis (P＜0.05). The expression of DKK1 was negatively correlated with SFRP4 and Wnt1 in SCC group (P＜0.05). The expression of SFRP4 was positively correlated with Wnt1 in SCC group (P＜0.05). Conclusion The roles of SFRP4 and Wnt1 are syn-ergistic interactions in the development of SCC. DKK1 is an inhibiting factor of SCC.

Objective To investigate the correlation between 24 h urinary protein quantitation and pregnancy outcome in patients with pre-eclampsia.Methods A total of 332 pre-eclampsia patients were selected in Tongji Hospital from January 2014 to December 2016.The patients were divided into microalbuminuria group(24 h urinary protein quantification ＜ 0.3 g,n =46),mild proteinuria group (0.3 g ≤ 24 h urinary protein quantification ＜ 2.0 g,n =98),moderate proteinuria group (2.0 g ≤ 24 h urinary protein quantification ＜ 5.0 g,n =71) and severe proteinuria group(24 h urinary protein quantification ≥ 5.0 g,n =117) according to the results of 24 h urinary protein quantification.The pregnancy outcomes were compared between the four groups.Results The 24 h urinary protein quantification and the serum creatinine,urea nitrogen,uric acid levels in the mild proteinuria group,moderate proteinuria group and severe proteinuria group were significantly higher than those in the microalbuminuria group (P ＜ 0.05);and gestational week was significantly shorter than that in the microalbuminuria group (P ＜ 0.05).The 24 h urinary protein quantification and serum urea nitrogen,uric acid levels in the moderate proteinuria group were significantly higher than those in the mild proteinuria group (P ＜ 0.05);and gestational week was significantly shorter than that in the mild proteinuria group (P ＜ 0.05);but there was no significant difference in serum creatinine level between the two groups (P ＞ 0.05).The 24 h urinary protein quantification,serum creatinine,urea nitrogen and uric acid levels in the severe proteinuria group were significantly higher than those in the mild proteinuria group (P ＜ 0.05);and the gestational week was significantly lower than that in the mild albuminuria group (P ＜ 0.05).The 24 h urinary protein quantification in the severe proteinuria group was significantly higher than that in the moderate proteinuria group (P ＜ 0.05),but there was no significant difference in the gestational week and serum creatinine,urea nitrogen,uric acid levels between the two groups (P ＞0.05).There was no significant difference in the rates of cesarean section and spontaneous labor between the four groups (P ＞0.05).The rate of induced labor in the moderate proteinuria group and the severe proteinuria group was significantly higher than that in the mild albuminuria group and the microalbuminuria group (P ＜ 0.05).There was no significant difference in the rate of induced labor between the mild proteinuria group and the microalbuminuria group (P ＞ 0.05).There was no significant difference in the rate of induced labor between the severe proteinuria group and the moderate proteinuria group (P ＞ 0.05).The incidence of complications in microalbuminuria group,mild proteinuria group,moderate proteinuria group and severe proteinuria group was 30.43％ (14/46),47.96％ (47/98),74.65％ (53/71) and 74.36％ (87/117) respectively;the incidence of complications in the moderate proteinuria group and the severe proteinuria group was significantly higher than that in the microalbuminuria group and the mild albuminuria group (P ＜ 0.05),but there was no significant difference in the incidence of complications between microalbuminuria group and mild albuminuria group (P ＞ 0.05),there was no significant difference in the incidence of complications between the moderate proteinuria group and the severe proteinuria group (P ＞0.05).The incidences of premature birth and neonatal asphyxia in the mild proteinuria group were significantly higher than that in the microalbuminuria group (P ＜ 0.05),and the body mass of the neonates was significantly lower than that in the microalbuminuria group (P ＜0.05),but there was no significant difference in the perinatal mortality rate and the incidences of fetal growth restriction(FGR) and poor neonatal resuscitation between the two groups (P ＞ 0.05).The incidences of FGR,premature birth,neonatal asphyxia,poor neonatal resuscitation and the perinatal mortality in the moderate proteinuria group and severe proteinuria group were significantly higher than those in the microalbuminuria group (P ＜ 0.05);and neonatal body mass was significantly lower than that in the mieroalbuminuria group (P ＜ 0.05).The incidences of FGR,premature birth and poor neonatal resuscitation and perinatal mortality in the moderate proteinuria group were significantly higher than those in the mild proteinuria group (P ＜ 0.05);and the neonatal body mass was significantly lower than that in the mild proteinuria group (P ＜ 0.05);but there was no significant difference in the neonatal asphyxia incidence between the two groups (P ＞ 0.05).The incidences of FGR,premature birth,neonatal asphyxia,poor neonatal resuscitation and perinatal mortality in the severe proteinuria group were significantly higher than those in the mild proteinuria group (P ＜ 0.05);and the body mass of the newborns was significantly lower than that in the mild albuminuria group (P ＜ 0.05).The incidence of neonatal asphyxia in the severe proteinuria group was significantly higher than that in the moderate proteinuria group (P ＜ 0.05),but there was no significant difference in the incidences of FGR,premature birth,poor neonatal resuscitation,perinatal mortality and neonatal body mass between the two groups (P ＞ 0.05).Conclusions The of 24 h urinary protein quantitation is closely related to the pregnancy outcome in patients with pre-eclampsia,the 24 h urinary protein quantification should be regularly detected in the patients with pre-eclampsia.When the urinary protein quantitation is more than 2.0 g,the incidences of maternal complications and poor prognosis of the perinatal infants is significantly higher,but the boundary value of the 24 h urinary protein quantitation for the diagnosis of severe pre-eclampsia still needs further large sample study.

Diagnostic criteria, as a critical component of clinical practice guidelines, play a direct role in guiding clinicians' diagnostic and treatment decisions. Although China has increasingly emphasized the development and updating of clinical guidelines in recent years, research focusing on the diagnostic criteria within these guidelines remains limited. This paper aims to explore the types of diagnostic criteria, the issues they present, and the processes involved in their formulation. Based on this analysis, suggestions are proposed to improve the recommendation and application of diagnostic criteria in Chinese guidelines.

Objective To investigate the influence of epidural analgesia on labor duration under the new partogram recommendations using quantile regression.Methods In this study,we recruited 300 nulliparous women at full term who were hospitalized in Department of Obstetrics and Gynecology,Tongji Medical College,Huazhong University of Science and Technology from May to September,2018.The participants who were willing to receive epidural analgesia during labor were assigned to the epidural group (n=150),and those who were not to the control group (n=150).Labor duration and delivery outcomes were analyzed by Student's t test,Mann-Whitney U test,Chi-square test and Fisher's exact test.Quantile regression models were also used to investigate the effect of epidural analgesia on labor duration.Results The median durations of first-and second-stage labor in the epidural group were 600(400-840) and 66(45-98) min,respectively,which were significantly longer than those of the control group [420(320-610) and 52(33-87) min] (Z=-4.273,P＜0.001;Z=-3.210,P=0.001).Quantile regression analysis showed that,for the first stage of labor,epidural analgesia was associated with labor prolongation,and had significant effects on all the percentiles (all P＜0.05).The regression coefficients increased (95.630-285.000) correspondingly as the percentiles of the labor duration (from 10th to 90th percentiles) increased.For the second stage of labor,epidural analgesia showed a significant impact on prolongation only between the 25th and 75th percentiles (coefficients:10.000～18.143;all P＜0.05).Although the epidural group had a significant higher episiotomy rate [46.8％(65/139) vs 33.3％(48/144),x2=5.318,P=0.021],more times of urine catheterization during labor [1(0-1) vs 0(0-1),Z=-0.974,P=0.001]and higher rate of oxytocin administration during labor [48.7％(73/150) vs 30.0％(45/150),x2=10.952,P=0.001],when compared with the control group,there was no significant difference in cesarean section rate,assisted vaginal delivery rate and neonatal outcomes between the two groups (all P＞0.05).Conclusions Epidural analgesia may associated with the prolongation of the first and second stage of labor,especially with the first stage of labor,but has no adverse effects on maternal and neonatal outcomes.

Objective:To summarize the clinical characteristics of patients with unicentric Castleman disease(UCD).Method:The clinical data of 8 abdominal UCD patients who received surgical resection at the Second Hospital of Hebei Medical University from Oct 2019 to Oct 2022 were analyzed, and the imaging characteristics, pathological types and prognosis were summarized.Result:There were 2 males and 6 females. The average age of patients was (33.0±13.7) years old, and their BMI was (23.2±4.5) kg/m 2. The median maximum diameter of the tumor was 4.5 (3.0-4.9) cm. The average postoperative hospital stay was 6.5 (3.3-12.0) days. One was lost during follow up, there was no recurrence or other postoperative complications in the remaining 7 patients. Conclusion:The incidence of unicentric Castleman disease is rare. Complete resection of the tumor is the main treatment for UCD patients, and the prognosis of UCD is good.

Objective To systematically review the efficacy of anti-inflammatory drugs in the treatment of diabetic nephropathy(DN).Methods Databases including PubMed,The Cochrane Library,EMbase,Web of Science,Scopus,Ovid,ProQuest,CBM,CNKI,WanFang Data,VIP and Duxiu data were electronically searched to collect randomized controlled trials(RCTs)of anti-inflammatory drugs for DN from inception to April 5,2022.Two reviewers independently screened the literature,extracted data,and assessed the risk of bias of the included studies.RevMan 5.4 software were then used to perform Meta-analysis.Results A total of 29 literature and 26 RCTs involving 4 095 patients were included.The results of Meta-analysis showed that compared with conventional treatment,conventional treatment combined with anti-inflammatory drugs could effectively reduce urinary albumin to creatinine ratio[SMD=-0.17,95％CI(-0.31,-0.03),P=0.02],urinary albumin excretion rate[SMD=-0.37,95％CI(-0.56,-0.18),P=0.000 1],urinary protein excretion rate[SMD=-0.97,95％CI(-1.29,-0.64),P=0.000 01],and glycosylated hemoglobin[SMD=-0.17,95％CI(-0.27,-0.08),P=0.000 4],while there was no significant difference in reducing serum creatinine[SMD=-0.04,95％CI(-0.19,0.1),P=0.57],urea nitrogen[MD=-0.23,95％CI(-0.50,0.04),P=0.09]and fasting blood glucose[SMD=-0.15,95％CI(-0.32,0.02),P=0.08].There was no statistically significant difference in changing glomerular filtration rate(GFR)[SMD=-0.04,95％CI(-0.15,0.07),P=0.47]with multiple drugs,except for a few drugs.Conclusion Conventional treatment combined with anti-inflammatory drugs can better improve the level of proteinuria in patients with DN,but the improvement of renal function is not obvious.Due to the limitations of the number of included studies and the duration of treatment,the above conclusion needs to be verified by more high-quality studies.

In this study,the current status for breast diseases in a region with high-incidence of cervical cancer were epidemiologically investigated.From March to August,2009,17618 women,from Wufeng area of Hubei province,China,were recruited to screen breast diseases by using breast infrared diagnostic apparatus.Other diagnostic methods,such as B-mode ultrasound,X-ray mammography,needle biopsy and pathological examination were,if necessary,used to further confirm the diagnosis.The screening showed that 5990 of 17618 cases (34.00％) had breast diseases,5843 (33.16％) had mammary gland hyperplasia,48 (0.27％) had breast fibroadenoma,ll (0.06％) had breast carcinoma,and 88 (0.50％) had other breast diseases.The peak morbidity of breast cancer was found in the women aged 50-0 ages.The morbidity of breast cancer was significantly increased in women elder than or equal to 50 years old (n=8,0.157％) in comparison with that in the subjects younger than 50 years old (n=3,0.024％) (u=2.327,P＜0.05).It was shown that the occurrence of breast diseases was concentrated in women aged 20-40 years,while the total morbidity reached its peak at the age of 30 years and then decreased sharply after age of 40.Compared with the patients elder than or equal to 40 years old (n=3289,27.46％),the morbidity rate of breast diseases was significantly increased in women less than 40 years old (2648 cases,47.18％; P＜0.001).However,there was no significant difference in the morbidity of breast diseases between the age group of 20-29 years and that of 30-39 years (P=0.453),and both of them were high.There was no significant association between the morbidity of breast diseases and cervical cancer.Since the morbidity of breast diseases was higher among young women,more attention should be paid to the screening of breast diseases among young women for early diagnosis.

Objective:To study the effect of iron deficiency level for oral iron absorption in iron deficient patients.Methods:37 non-pregnant female patients who were diagnosed with iron deficiency and 13 healthy females who completed their physical examination at the outpatient department of the Anemia Center of the Institute of Hematology & Blood Diseases Hospital from July 2018 to June 2020 were included. Hepcidin and C2-C0 of oral iron absorption test were analyzed in different iron deficiency and serum ferritin level.Results:The median of Hepcidin in IDA, ID/IDE and healthy control group were 4.9 (2.17-32.86) , 26.98 (11.02-49.71) and 69.89 (42.23-138.96) μg/L ( P<0.001) , respectively. Hepcidin level of IDA group was lower than that of ID/IDE group (adjusted P=0.005) and healthy control (adjusted P<0.001) . Hepcidin level of ID/IDE group had no significant difference compared with healthy control (adjusted P=0.22) . The mean of C2-C0 in IDA, ID/IDE and healthy control group were (35.30±21.68) , (37.90±14.06) and (23.57±10.14) μmol/L ( P=0.130) , respectively. Multilinear regression analysis showed C0, SF, sTFR and HGB were independent factors for Hepcidin in iron deficient patients, with an equation of Hepcidin=-31.842-0.642*C0+2.239*SF+1.778*sTFR+0.365*HGB-0.274*RET-HB. We didn't find independent factor of C2-C0. Conclusion:The degree of iron deficiency had an effect on oral iron absorption. Patients of ID/IDE group absorbed iron more slowly than patients of IDA group. Iron deficient patients with normal gastrointestinal function absorbed more iron by oral administration when they were in a more serious iron deficient stage. Hepcidin was a better parameter to distinguish iron absorption level among different iron deficient patients than C2-C0 of oral iron absorption test.

Preeclampsia (PE) is a pregnancy-specific, multi-system disorder and the leading cause of maternal and perinatal morbidity and mortality in obstetrics worldwide. Excessive vasoconstriction and dysregulated coagulation function are closely associated with PE. Heat shock protein 20 (HSP20) is ubiquitously expressed under normal physiological conditions and has important roles in vascular dilatation and suppression of platelet aggregation. However, the role of HSP20 in the pathogenesis of PE remains unclear. In this study, we collected chorionic plate resistance arteries (CPAs) and serum from 118 healthy pregnant women and 80 women with PE and detected the levels of HSP20 and its phosphorylated form. Both HSP20 and phosphorylated HSP20 were downregulated in CPAs from women with PE. Comparison of the vasodilative ability of CPAs from the two groups showed impaired relaxation responses to acetyl choline in preeclamptic vessels. In addition to the reduced HSP20 in serum from women with PE, the platelet distribution width and mean platelet volume were also decreased, and the activated partial thromboplastin time and thromboplastin time were elevated.With regard to the vital roles of HSP20 in mediating vasorelaxation and coagulation function, the decreased HSP20 might contribute to the pathogenesis of PE.
