OBJECTIVE@#To provide guidance for hip replacement by analyzing the variation of femoral head rotation center in different hip diseases.@*METHODS@#A total of 5 459 patients were collected from March 2016 to June 2021, who took positive and proportional plain films of both hips for various reasons. The relative position between the rotation center of the femoral head and the apex of the greater trochanter was measured. The positive variation is more than 2 mm above the top of the great trochanter, and the negative variation is more than 2 mm below the top of the great trochanter. A total of 831 patients with variation of femoral head rotation center were collected and were divided into 4 groups according to different diseases, and the variation was counted respectively. There were 15 cases in the normal group involving 10 cases of positive variation and 5 cases of negative variation. There were 145 cases of avascular necrosis of femoral head involving 25 cases of positive variation and 120 cases of negative variation. There were 346 cases of congenital hip dysplasia involving 225 cases of positive variation(including 25 cases of typeⅠ, 70 cases of type Ⅱ, 115 cases of type Ⅲ and 15 cases of type Ⅳ), and 121 cases of negative variation(including 50 cases of crowe typeⅠ, 60 cases of typeⅡ, 10 cases of type Ⅲ and 1 case of type Ⅳ). There were 325 cases of hip osteoarthritis group involving 45 cases of positive variation and 280 cases of negative variation.@*RESULTS@#There was significant difference in variation of femoral head rotation center among the four groups(P<0.05). There was significant difference in variation of femoral head rotation center among different types of congenital hip dysplasia(P<0.05). There were significant differences in cervical trunk angle and eccentricity among different variations of femoral head rotation center(P<0.05).@*CONCLUSION@#The variation of femoral head rotation center is related to cervical trunk angle and eccentricity. The variation of femoral head rotation center is an important factor in hip diseases. The variation of femoral head rotation center is different in different hip diseases. Avascular necrosis of the femoral head and osteoarthritis of the hip were mostly negative variations. With the aggravation of congenital hip dysplasia, the variation of femoral head rotation center gradually changed from negative variation to positive variation.The variation of femoral head rotation center should be paid attention to in the preoperative planning of hip arthroplasty. It is of great significance to select the appropriate prosthesis and place the prosthesis accurately.

Copy number variant sequencing for chromosome analysis in 487 fetuses with increased nuchal translucency / 中华围产医学杂志

Objective:To analyze the genetic etiology of 487 fetuses with increased nuchal translucency (NT) using copy number variant sequencing (CNV-seq) and explore the relationship between increased NT and chromosomal abnormality.Methods:A retrospective study was performed on 487 fetuses with increased NT who received CNV-seq in the First Affiliated Hospital of Zhengzhou University from January 2018 to December 2020. These fetuses either had NT of ≥3.0-<3.5 mm (Group A, n=129) or ≥3.5 mm (Group B, n=358), the distribution and incidence of chromosomal abnormalities in the two sets of fetuses were analyzed using Chi square test or Fisher's exact test. Results:Fetuses with abnormal chromosomes accounted for 25.9%(126/487) of cases, including 107 with chromosome aneuploidy (22.0%) and 19 with pathogenic or likely pathogenic copy number variation (CNV, 3.9%). The detection rate of fetal aneuploidy in Group B was higher than that in Group A [14.0% (18/129) vs 24.9% (89/358), χ2=6.58, P=0.010]. However, no significant difference was observed regarding the detection rate of pathogenic or likely pathogenic CNV between the two groups ( χ2=0.30, P=0.584). Conclusions:The risk of fetal chromosome aneuploidy increased with NT thickness, but not with pathogenic or likely pathogenic CNV, which needed further verification due to the small sample size. CNV-seq is an option to detect the conventional detection methods for the genetic etiology of NT thickening fetuses.

Incidence of extrauterine growth retardation and its risk factors in very preterm infants during hospitalization: a multicenter prospective study / 中国当代儿科杂志

OBJECTIVES@#To investigate the incidence of extrauterine growth retardation (EUGR) and its risk factors in very preterm infants (VPIs) during hospitalization in China.@*METHODS@#A prospective multicenter study was performed on the medical data of 2 514 VPIs who were hospitalized in the department of neonatology in 28 hospitals from 7 areas of China between September 2019 and December 2020. According to the presence or absence of EUGR based on the evaluation of body weight at the corrected gestational age of 36 weeks or at discharge, the VPIs were classified to two groups: EUGR group (n=1 189) and non-EUGR (n=1 325). The clinical features were compared between the two groups, and the incidence of EUGR and risk factors for EUGR were examined.@*RESULTS@#The incidence of EUGR was 47.30% (1 189/2 514) evaluated by weight. The multivariate logistic regression analysis showed that higher weight growth velocity after regaining birth weight and higher cumulative calorie intake during the first week of hospitalization were protective factors against EUGR (P<0.05), while small-for-gestational-age birth, prolonged time to the initiation of total enteral feeding, prolonged cumulative fasting time, lower breast milk intake before starting human milk fortifiers, prolonged time to the initiation of full fortified feeding, and moderate-to-severe bronchopulmonary dysplasia were risk factors for EUGR (P<0.05).@*CONCLUSIONS@#It is crucial to reduce the incidence of EUGR by achieving total enteral feeding as early as possible, strengthening breastfeeding, increasing calorie intake in the first week after birth, improving the velocity of weight gain, and preventing moderate-severe bronchopulmonary dysplasia in VPIs.

Therefore, this article reviews the preoperative risk factors and surgical strategies affecting the long-term survival of elderly patients with early-stage NSCLC(non-small cell lung cancer), thus increasing the clinician’s awareness of elderly NSCLC, which is of great significance to help make reasonable surgical strategies and improve the prognosis.

The predictive value of dynamic changes of coagulation function for the occurrence and progression of isolated distal deep vein thrombosis of lower limbs in patients with acute brain injury / 中华危重病急救医学

Objective:To analyze risk factors for the occurrence and progression of isolated distal deep vein thrombosis (IDDVT) of lower limbs, and to explore the predictive value of dynamic changes of coagulation index D-dimer on the occurrence and progression of IDDVT in acute brain injury (ABI) patients during perioperative period.Methods:A retrospective case-control study was conducted. Perioperative ABI patients admitted to department of neurocritical care unit (NCCU) of the First Affiliated Hospital of University of Science and Technology of China from September 2019 to May 2020 were enrolled. Patients' baseline characteristics, disease characteristics, treatment approaches, outcomes and coagulation function index at 1, 2-4, 5-7 and > 7 days post operation were analyzed between patients with IDDVT and patients with progressive IDDVT. Risk factors for IDDVT occurrence and progression were identified by multivariate Logistic regression. Receiver operating characteristic curve (ROC curve) were drawn to assess the predictive value of coagulation indexes for IDDVT occurrence and progression.Results:A total of 164 ABI patients were enrolled. Most of the patients were elderly [age was 60 (51, 69) years], male [99 cases (60.4%)], and severe cases [Glasgow coma score (GCS) at admission was 6 (5, 8)]. The rates of IDDVT occurrence and progression were 61.6% (101 cases) and 16.8% (17 cases), respectively, the rate of proximal deep venous thrombosis (DVT) was 12.8% (21 cases). Compared with the IDDVT group (101 patients), patients without IDDVT group were younger (years: 55±13 vs. 62±13), length of intensive care unit (ICU) stay were shorter (days: 12±6 vs. 15±7), body mass index (BMI) and GCS at admission were higher [59 patients, BMI (kg/m 2): 23±5 vs. 19±8, GCS scores: 7±2 vs. 6±2], the differences were statistically significant (all P < 0.05). Compared with patients with IDDVT progression group, male patients were fewer [61.9% (52/84) vs. 88.2% (15/17)], the proportion of transfusion of red blood cell and anticoagulant therapy were lower [8.3% (7/84) vs. 29.4% (5/17) and 47.6% (40/84) vs. 94.1% (16/17)], the proportion of cerebral herniation was higher [42.9% (38/84) vs. 11.8% (2/17)] in patients without IDDVT progressive group. All of the differences were statistically significant (all P < 0.05). D-dimer were increased in two groups of whether IDDVT occurrence or not over time. D-dimer peaked on 5-7 days after surgery in IDDVT occurrence group, and then decreased. D-dimer peaked at > 7 days after surgery in patients without IDDVT. With time, D-dimer were increased in groups of whether IDDVT progression or not, both peaked at 5-7 days postoperation, and then decreased. Compared with non-IDDVTgroup, D-dimer was significantly increased in IDDVT group from 2-4 days after surgery [mg/L: 4.1 (2.3, 8.0) vs. 2.4 (1.7, 3.4), P < 0.05], and lasted until 5-7 days [mg/L: 5.5 (3.3, 11.4) vs. 3.9 (2.6, 5.8), P < 0.05]. Compared with IDDVT group, D-dimer was significantly increased in IDDVT progressive group from 2-4 days [mg/L: 11.2 (4.7, 20.0) vs. 3.7 (2.1, 6.8), P < 0.05], and lasted until 7 days [mg/L: 11.0 (3.0, 18.9) vs. 4.1 (2.6, 6.5), P < 0.05]. Multivariate Logistic regression analysis showed that age > 60 years [odds ratio ( OR) = 3.43, 95% confidence interval (95% CI) was 1.69-6.96, P = 0.001], GCS score at admission > 8 ( OR = 0.35, 95% CI was 0.17-0.76, P = 0.008), length of ICU stay > 13 days ( OR = 2.25, 95% CI was 1.08-4.70, P = 0.031) were risk factors for IDDVT. Gender ( OR = 0.19, 95% CI was 0.02-0.71, P = 0.019), transfusion of red blood cell ( OR = 6.50, 95% CI was 1.33-31.94, P = 0.021), cerebral herniation ( OR = 0.18, 95% CI was 0.37-0.90, P = 0.036) were risk factors for IDDVT profression. ROC curve analysis showed that age and D-dimer at 5-7 days were predicators of IDDVT [the area under curve ROC (AUC) were 0.68 and 0.72, 95% CI were 0.60-0.75 and 0.64-0.80, both P value were 0.000 1]. When the cut-off value of age was 60 years old and the D-dimer was 5.4 mg/L, the sensitivity were 60.6% and 54.4%, specificity were 71.2% and 80.9%, respectively, positive predictive value were 78.7%, 84.5%, negative predictive value were 51.2%, 48.1%, respectively. The elevation of D-dimer to 3.9 times at days 5-7 compared with day 1 of NCCU stay was a predicator of IDDVT progression (AUC = 0.81, 95% CI was 0.71-0.88, P = 0.000 1). The sensitivity, specificity, positive predictive value and negative predictive value were 76.5%, 74.6%, 41.9% and 93.0%, respectively. Conclusions:IDDVT occurrence and progressiveare common in severe ABI patients during perioperative period. The dynamic change of D-dimer, especially at days 5-7, is a valuable predictor of IDDVT progressionin ABI patients, which is helpful for guiding implementation of deep vein ultrasound of lower limb.

Purification and component identification of total proanthocyanidins in Choerospondias axillaris pericarp / 中国中药杂志

The present study determined the quantitative markers of total proanthocyanidins in the purification of the industrial waste Choerospondias axillaris pericarp based on the comparison results of high-performance liquid chromatography(HPLC) and mass spectrometry(MS) and optimized the purification process with two stable procyanidins as markers. The adsorption and desorption of five different macroporous adsorption resins, the static adsorption kinetics curve of NKA-Ⅱ resin, the maximum sample load, and the gradient elution were investigated. The UPLC-Q-TOF-MS/MS was employed for qualitative analysis of the newly-prepared total proanthocyanidins of C. axillaris pericarp. As revealed by the results, NKA-Ⅱ resin displayed strong adsorption and desorption toward total proanthocyanidins. The sample solution(50 mg·mL~(-1)) was prepared from 70% ethanol crude extract of C. axillaris pericarp dissolved in water and 7-fold BV of the sample solution was loaded, followed by static adsorption for 12 h. After 8-fold BV of distilled water and 6-fold BV of 10% ethanol were employed to remove impurities, the solution was eluted with 8-fold BV of 50% ethanol, concentrated, and dried under reduced pressure, and purified total proanthocyanidin powder was therefore obtained. Measured by vanillin-hydrochloric acid method, the purity and transfer rate of total proanthocyanidins were 47.67% and 59.92%, respectively, indicating the feasibi-lity of the optimized process. UPLC-Q-TOF-MS/MS qualitative analysis identified 16 procyanidins in C. axillaris total proanthocyanidins. The optimized purification process is simple in operation and accurate in component identification, and it can be applied to the process investigation of a class of components that are difficult to be separated and purified. It can also provide technical support and research ideas for the comprehensive utilization of industrial waste.

Analysis of three families with recurrence of non-immune hydrops fetalis by trio whole exome sequencing / 中华医学遗传学杂志

OBJECTIVE@#To explore the genetic basis of three families with recurrence of non-immune hydrops fetalis (NIHF) but negative result by copy number variation sequencing (CNV-seq).@*METHODS@#Amniotic fluid sample and/or abortive tissues of the fetuses were collected and subjected to CNV-seq analysis. Peripheral blood samples of the parents were also taken for trio whole exome sequencing (trio WES).@*RESULTS@#Fetus 1 was found to harbor heterozygous c.976G>T(p.Glu326*) variant of the SOX18 gene in addition with compound heterozygous variants c.844C>T(p.Arg282Trp) and c.9472+1G>A of the RYR1 gene. The three variants were all inherited from its parents and have been associated with the etiology of NIHF. Based on the American College of Medical Genetics and Genomics (ACMG) standards and guidelines, the c.976G>T variant of SOX18 gene and c.9472+1G>A of RYR1 gene were predicted to be pathogenic (PVS1+PM2+PP3+PP4, PVS1+PM2+PP3), and c.844C>T variant of RYR1 gene to be likely pathogenic (PM1+PM2+PP3). Fetus 2 was found to harbor compound heterozygous variants c.6682C>T(p.Gln2228*) and c.4373_4383del(p.Val1458Alafs*63) of the PIEZO1 gene. Both variants were also inherited from its parents and are associated with the etiology of NIHF. Based on ACMG standards and guidelines, both c.6682C>T and c.4373_4383del variants of PIEZO1 gene were predicted to be pathogenic (PVS1+PM2+PP4, PVS1+PM2). Fetus 3 was found to harbor compound heterozygous variants of the TTN gene c.29860G>C(p.Asp9954His) and c.21107A>T(p.Asp7036Val), which were respectively inherited from its parents. Both variants have been strongly associated with the phenotype, though the connection between the etiology of NIHF and variants of the TTN gene remains elusive. Based on ACMG standards and guidelines, the c.29860G>C and c.21107A>T variants of TTN gene were predicted to be likely pathogenic (PM1+PM2+PP3).@*CONCLUSION@#Trio WES can improve the diagnosis rate of NIHF with a negative result by CNV-seq. Considering the urgency of prenatal diagnosis, CNV-seq and trio WES should be carried out at the same time for fetuses with NIHF.

The primary endpoint was death from any cause during ICU stay. Results: A total of 852 and 238 patients with severe trauma were assigned to the derivation group and validation group, respectively. Area under the ROC curve (AUC) was 0.826 [95% confidence interval (CI)=0.794-0.855)] for NISS, 0.802 (95% CI=0.768-0.832) for APACHE II, 0.808 (95% CI=0.774-0.838) for NGCS, 0.859 (95% CI=0.829 -0.886) for NISS+NGCS, 0.864 (95% CI=0.835-0.890) for APACHE II +NGCS, 0.896 (95% CI=0.869-0.929) for NISS+APACHE II in the derivation cohort. Similarly, the score of NISS+APACHE II was also better than the other five scores in the validation cohort (AUC=0.782; 95% CI=0.725-0.833) and had a good calibration (P=0.41). Conclusions: Taking into account anatomical and physiological parameters completely, the combination of NISS and APACHE II performs better than NISS, APACHE II, NGCS, NISS+NGCS, APACHE II +NGCS for predicting mortality in ICU severe trauma patients. It is needful to develop models that contain various types of accessible predictors (demographic variables, injury cause/mechanism, physiological and anatomical variables, etc.) as comprehensive as possible.

Distal pancreatectomy with celiac axis resection(DP-CAR) for pancreatic cancer: An analysis of 40 cases / 中国实用外科杂志

OBJECTIVE: To assess the safety and efficacy of distal pancreatectomy with celiac axis resection(DP-CAR).METHODS: The clinical and pathological data of 40 patients with pancreatic cancer who underwent DP-CAR at the Changhai Hospital affiliated to the Naval Military Medical University from January 2012 to December 2016 were analyzed retrospectively.The postoperative incidence of complications,mortality and overall survival were analyzed respectively.RESULTS: The incidence of complication in the 40 patients(Clavien-Dindo score≥2) was 32.5%(13 cases)including 1 case(2.5%) died of liver failure in 90 days after surgery due to hepatic ischemia,6 cases(15.0%) of grade B or above pancreatic fistula,7 cases(17.5%) of gastric emptying disorder,6 cases(15,0%) of severe abdominal infection,4 cases(10.0%) of chyle leakage,and 4 cases(10%) of postpancreatectomy hemorrhage(PPH).Total median survival was19.1 months(IQR 8.9,30.8 months),one-year,three-year and five-year survival rate:62.5%,17.5% and 5.0%.Patients of T4(median survival:T4 14.2 months vs.T1-3 24.1 months,P=0.0225),lymph node metastasis of N1-2(median survival:N1-2 8.8 months vs.NO 23.2 months,P=0.00967) had a worse median survival time.CONCLUSION: In high-selective patients with pancreatic body/tail cancer,the morbidity,mortality and median survival after DP-CAR surgery are acceptable,and patients with T4 and regional lymph nodes enlargement in preoperative imaging evaluation should be performed neoadjuvant therapy,and then be re-evaluated before DP-CAR.

Evaluation and Comparison of Thromboelastography and Conventional Coagulation Tests for Blood Coagulation Function in Children with Henoch-Schönlein Purpura / 中国实验血液学杂志

OBJECTIVE@#To investigate the efficacy of disease control, survival time and safely in treatment of newly diagnosed multiple mycloma patients with different dose of tenalidomide regimens.@*METHODS@#The clinical data of 116 patients with multiple myeloma from June 2011 to June 2015 were collected and analyzed retrospectively. According to doses of used lenalidomide based on dexamethasone plus lenalidomide regimen 116 patients were divided into 2 groups: conventional dose group (58 cases) and low dose group (58 cases). The ORR, PFS rate and OS rate during followed-up for 3 years, KPS score, RNS score and immunophenotypic index before and after treatment and drug toxicity incidence were compared between 2 groups.@*RESULTS@#The ORR for 2 treatment courses of low dose group was significantly lower than that in conventienal dose group (P＜0.05). The ORR for 4 and 6 treatment courses was not significantly different between 2 groups (P＞0.05). The PFS rate and OS rate during followed-up for 3 years was no significantly different between 2 groups (P＞0.05). The KPS score and RNS score after treatment of low dose group were significantly better than those in conventional dose group and before treatment (P＜0.05). The levels of immunophenotypic index after treatment of both groups were significantly better than those before treatment (P＜0.05). The incidence of III-IV grade hematological toxicity, pulmonary infection and herpes were not significantly different between 2 groups (P＞0.05). The incidence of peripheral neuropathy and gastrointestinal reactions in the low dose group were significantly lower than that in conventional dose group (P＜0.05).@*CONCLUSION@#Conventional and low doses of lenalidomide possess the same control effects and survival time for treatment of newly dingnosed patients with multiple myeloma; Despite, the initiation of effects from the low dose lenalidomide is relatively slower, it contributes to raise the overall quality of life and reduce the risk of drug toxicity.

Correlation analysis of colon polyps'size,dysplasia and intestinal metaplasia / 安徽医科大学学报

The patients undergoing gastroscope and enteroscopy examination were respectively divided into gastric intestinal metaplasia group (n = 397) and non gastric intestinal metaplasia group (n = 360),and the differences in size,number,location and dysplasia of colonic polyps between the two groups were compared. In GIM group,the polyps incidence after classification of polyp size and colonic dysplasia was significantly higher than that in non GIM group (P < 0. 05),while the number and location of colonic polyps were no significant difference between two groups. By the logistic regression analysis,more than 50 years old of age,male,HP infection,the diameter of polyps are larger than 2. 0 cm,or dysplasia showed high possibility to appear gastric intestinal metaplasia (OR > 1,P< 0. 05),the diameter of colonic polyps are 1. 0 ～ 2. 0 cm which showed high possibility to non intestinal metaplasia (OR < 1,P < 0. 05),and there was no significant difference between the two groups in the incidence of GIM in colonic polyps less than 0. 5 cm or 0. 5 ～ 1. 0 cm in diameter. Not only age,gender and HP infection were related to the occurrence of IM,but the risk of GIM increased in patients with colonic polyps' diameter more than 2. 0 cm and dysplasia. Those who found colonic polyps > 2. 0 cm in diameter and polyps with dysplasia were suggested to undergo gastroscopy in order to find GIM early and follow up to improve the detection rate of early gastric cancer.
