ObjectiveTo explore the law of women reproductive aging based on theory of "seven-year period" in traditional Chinese medicine（TCM） through analyzing the characteristics of basic sex hormone levels and anti-müllerian hormone levels in women of different ages. MethodsThe data of female who visited Guangdong Provincial Hospital of Traditional Chinese Medicine from January 2018 to December 2022 and accepted basic hormone and anti-müllerian hormone determination were collected retrospectively. According to the age of subjects， they were divided into the "1-2 seven" group （under 21 years old）， "3 seven" group （21-27 years old）， "4 seven" group （28-34 years old）， "5 seven" group （35-41 years old）， "6 seven" group （42-48 years old） and "7 seven" and older group （49 years old and above）. The age， average menstrual cycle in the past 3 months， basic hormone levels including follicle stimulating hormone （FSH）， luteinizing hormone （LH）， estradiol （E₂）， testosterone （T） and FSH/LH value， and anti-müllerian hormone （AMH） levels were collected and compared. ResultsA total of 1221 cases were included. The differences in FSH， LH， FSH/LH values， E₂， T， AMH levels and average menstrual cycle among the groups were statistically significant （P＜0.05 or P＜0.01）. AMH peaked in the "3 seven" group. Compared to those in the "3 seven" group， the FSH/LH value in the "4 seven" group increased， while the LH， AMH and T levels decreased， and the menstrual cycle was shortened （P＜0.01）. The FSH/LH， LH， AMH， T and menstrual cycle in the "5 seven" group were consistent with the changing trend of those in the "4 seven" group， while the FSH and E₂ levels in the "5 seven" group were significantly higher （P＜0.05 or P＜0.01）. Compared to those in the "5 seven" group， the FSH， LH and E₂ levels of the "6 seven" group increased， and the AMH and T levels continued to decrease （P＜0.05 or P＜0.01）. Compared to those in the "6 seven" group， the FSH and LH levels of the "7 seven" and older group continued to increase， and the AMH and E₂ levels decreased （P＜0.01）. ConclusionThe law of women reproductive aging in the "seven-year period" theory is basically consistent with the characteristics of basic sex hormone levels and anti-müllerian hormone levels in women of different ages. The reproductive capacity reaches its peak in the "three-seven-year period" and gradually moves towards reproductive aging in the "four-seven-year period".

Objective:To investigate the value of BRAF V600E and multigene detection and stratified application for the diagnosis of thyroid nodules.Methods:A total of 1 117 patients with thyroid nodules resection at Nanjing Gulou Hospital from December 2020 to July 2022 were enrolled in the study. Fine needle aspiration (FNA) and core biopsy samplings were performed for cytopathologic examination and genetic testings; the findings were combined with BSRTC classification. The diagnostic performance of BRAF V600E and multigene detection were compared.Results:Among the 1, 117 patients who underwent thyroid nodules resection, 285 were male and 832 were female, with a median age of 46 years (range: 24-76 years). Postoperative histopathologic examination confirmed 1 040 cases of thyroid cancer and 77 cases of benign nodules. The sensitivity (87.0% vs. 80.8%, P<0.01) and diagnostic accuracy (87.9% vs. 82.1%, P<0.01) of multigene detection were significantly higher than those of BRAF V600E detection. The result of multigene detection showed that BRAF V600E mutation was the most common finding, followed by CCDC6-RET (E1-E12) fusion, ETV6-NTRK3 fusion, and KRAS mutation. Multigene detection had a higher sensitivity (81.9% vs. 72.8%, P<0.01) and lower cancer risk in wild-type (47.6% vs. 57.7%, P=0.069) than BRAF V600E detection in BSRTCⅠ-Ⅴ lesions. Compared with BRAF V600E detection, multigene had no significant difference of sensitivity in BSRTC Ⅰ lesions, but significantly higher sensitivity (86.3% vs 74.0%, P<0.01) in BSRTC Ⅲ lesions. Conclusions:Genetic detection can be used as an effective tool for the diagnosis of thyroid nodules. A stratified application of molecular markers in the diagnosis of thyroid nodules is proposed. Combined with FNA, single gene or multigene detection both can effectively assist in the diagnosis of thyroid nodules. Moreover, multigene detection is superior to single gene detection. For BSRTC Ⅲ lesion with wild-type BRAF, multigene detection can be considered with a repeated FNA.

Objective:To develop a Core Competency Scale for Ophthalmic Specialist Nurses and test its reliability and validity.Methods:This study was a questionnaire development study. This study transformed the core competency evaluation indicators for ophthalmic specialist nurses constructed through literature review, semi-structured interviews, expert consultations, and other methods to form the initial draft of the Core Competency Scale for Ophthalmic Specialist Nurses. From October 2022 to March 2023, a survey was conducted on 364 ophthalmic specialist nurses in China using purposive and snowball sampling. Item analysis, exploratory factor analysis, and reliability testing were performed on the scale.Results:The final Core Competency Scale for Ophthalmic Specialist Nurses included six dimensions of ophthalmic specialized knowledge, ophthalmic specialized skills, essential nursing practice ability, communication and education ability, scientific research ability, and professional competence, totaling 30 items. Exploratory factor analysis extracted six common factors, with a cumulative variance contribution rate of 73.077%. The total Cronbach's α coefficient of the scale was 0.955, the half reliability coefficient was 0.796, and the retest reliability coefficient was 0.973.Conclusions:The Core Competency Scale for Ophthalmic Specialist Nurses has good reliability and validity, which can be used to evaluate the core competency of ophthalmic specialist nurses.

Bilateral Wilms'tumor (BWT) affects approximately 5% of children with WT. The goal of treatment in BWT is to preserve normal renal function as much as possible, in order to postpone and reduce the risk of end-stage renal disease and other long-term complications. For neoadjuvant chemotherapy, vincristine/dactinomycin/doxorubicin is used in cases with favorable histology. Cases with diffuse anaplasia or other unfavorable histology receive an intensified regimen, including additional agents such as ifosfamide, cy-clophosphamide, carboplatin, and others. Nephron-sparing surgery is performed to preserve long-term renal function. Radiotherapy is given according to local staging, when margins or lymph nodes are positive, or tumor spillage has occurred, or pathological type is ana-plasia. The survival rate of relapsed BWT is low. Some experts suggest that patients with recurrent BWT are most likely to benefit from high-dose therapy including stem-cell transplantation, but this remains controversial.

Objective To study the clinical, endoscopic and pathological features of gastrointestinal and mesenteric reactive nodular fibrous pseudotumor (RNFPT). Methods A retrospective analysis was conducted on data of 24 RNFPT patients in Nanjing Drum Tower Hospital admitted from October 2008 to June 2016. The clinical, endoscopic, pathological and immunohistochemical characteristics were analyzed. Results Among the 24 patients, 16 complained about discomfort in the upper abdomen and 10 had a history of surgery or trauma. Twenty-one had isolated masses and 3 had multiple masses, with diameter of 0. 5-4. 0 cm. Endoscopically, the tumors were mainly hard submucosal masses with broad base, and smooth surface with no mucosal bridge. Seventeen patients underwent endoscopic ultrasonography, which showed low echoes in lesions and nonuniform echoes partly. Among them, 13 lesions derived from muscularis, 4 others from submucosa. Microscopically, the tumors had clear boundary with no envelope, and most areas showed disorderly arranged spindle cells and extensively collagenous degenerated mesenchyma. The spindle cells had shuttle fibroblast-like morphology and elongated nucleus with no visible necrosis or mitosis. Inflammatory cells scattered between the tumor cells, and lymphoid follicles and calcium deposition could be seen in local areas. Immunohistochemically, SMA was focally positive in 7 cases and only 4 cases expressed CD117 scattered. Desmin, Dog-1, CD34, ALK-1 and S-100 were all negative, and Ki-67 proliferation index was lower than 1％. Conclusion RNFPT has diverse clinical manifestations, with a good prognosis and unlikely recurrences, and should be distinguished from spindle cell tumors.

Objective To study the changes of micro structure of white matter and gray matter in alcohol dependent patients by using diffusion kurtosis imaging(DKI) based on the method of voxel-based analysis.Methods Thirty alcohol dependent individuals and twenty healthy control volunteers,matched in gender, age, handedness and education, were enrolled as the alcohol dependent group and control group from September 2016 to June 2017.Michigan alcoholism screening test(MAST)was done for all subjects.All the subjects underwent DKI data acquisition by MR scanning. The relevant parameters were obtained by DKE software, including fractional anisotropy(FA), mean diffusivity(MD), axial diffusivity(AD), radial diffusivity(RD), mean kurtosis(MK), axial kurtosis(AK), radial kurtosis(RK), FA of kurtosis(FAK). Independent sample t test was performed to evaluate the significant difference of DKI parameters of two groups,meanwhile,the correlation analysis was conducted in DKI parameter values of different brain regions and MAST scores. Results Compared with the healthy control group, the FA value, MK value and RK value were decreased while the RD value was increased in alcohol dependence group, and there was significant difference between the two groups respectively(P<0.001). There was no significant difference between the two groups in the other parameters (AD, MD, AK, FAK). Compared with the healthy control group,the FA values of left lingual gyrus(164 voxels,t=-5.582)and left hippocampus(38 voxels,t=-3.664) increased;the MK value of left cerebellum posterior lobe(71 voxels,t=-4.004)reduced;the RK value of left cerebellum posterior lobe(67 voxels, t=-4.174), left middle cingulum(32 voxels, t=-3.925), left superior parietal gyrus(36 voxels,t=-3.812)reduced;and the RD value of the left inferior parietal gyrus(31 voxels,t=3.731)increased in alcohol dependence group.There was no correlation between MAST score and the value of DKI parameters. Conclusions There are dominant areas of brain injury in patients with alcohol dependence. The DKI parameters can reflect the changes of the whole brain microstructure of alcohol dependent patients and provide imaging basis in the diagnosis of alcohol dependence.

Objective To investigate the clinicopathological characteristics and the expression of related molecular markers of heterotopic pancreas for better understanding and avoiding overtreatment of this disease.Methods From 24th March 2009 to 10th November 2016,92 patients with heterotopic pancreas in upper digestive tract diagnosed after endoscopic submucosal dissection(ESD),were collected. Tissues were sectioned and pathologically classified by Heinrich classification.The expressions of seven different molecular markers including cytokeratin(CK)19,insulin,trypsin,Ki-67,p53,CD133 and CD56 were detected by immunohistochemistry staining. Clinical features, pathological features and immunohistochemical results were retrospectively analyzed.Analysis of variance and Kruskal-Wallis test were used.Results According to Heinrich classification,the percentages of type Ⅰ,Ⅱ,and Ⅲ of heterotopic pancreas were 27.2%(25/92),63.0%(58/92)and 9.8%(9/92),respectively.There was no type Ⅳ patients.The heterotopic pancreas mainly located in stomach with proportion being about 91.3%(84/92)of the total heterotopic pancreas.CK19(the marker of pancreas ducts),insulin(as marker of endocrine function)and trypsin(as the marker of exocrine function)were all expressed in heterotopic pancreas.The positive rate of CD56,a pancreatic neuroendocrine marker,was 66.3%(61/92).The umbilicus like depression was the typical endoscopic appearance of heterotopic pancreas,which only found in 29 patients(31.5%).The average rate of Ki-67,cell proliferation index,was(2.08 ± 1.41)%.The expression of mutant p53 was negative in all 92 cases of heterotopic pancreas.The average staining area of CD133,a marker of pancreatic cancer stem cell,was(2.53 ± 2.43)%.The average follow-up period of 92 patients was(43.6 ± 27.5)months.No relapse and malignant change were found and all patients survived after ESD.Conclusions Heterotopic pancreas has normal pancreatic construction and function.The cell proliferation index is low in heterotopic pancreas and no mutant p53 expression is found.The expression of CD133 is also low.Heterotopic pancreas is a congenital benign disease which requires a long-term follow-up rather than overtreatment.

Objective To investigate the incidence and risk factors of the complications in perioperative intra-aortic balloon pump (IABP) supported cardiac surgical patients. Methods The clinical data of adult cardiac surgery patients undergoing IABP in Fuwai Hospital from January 2005 to January 2017 were enrolled. The patients were divided into complications group and no complications group. Demographic characteristics, diagnosis, perioperative clinical parameters, IABP related data, and IABP complications (including ischemia, bleeding, vascular injury and mechanical problems) were collected. The incremental risk factors of complications related IABP were analyzed by logistic regression. Results During the 12-year period, 522 patients received IABP support, with 388 male and 134 female; the mean age was (61.79±9.35) years; the complications related to IABP occurred in 25 patients, and overall complication rate was 4.79%; 87 IABP patients were dead in-hospital, the overall mortality was 16.67%, no patient died due to complications. The complications rate was higher in the female patients (40.00% vs. 24.95%), and was more in patients with age ≥ 65 years old (80.00% vs. 38.03%), more with higher body mass index [BMI (kg/m2): 25.45±13.71 vs. 22.95±3.45], diabetes mellitus (44.00% vs. 26.76%), combination treatment with extra-corporeal membranous oxygenation (ECMO: 20.00% vs. 5.03%) and prolonged IABP support time (hours: 134.4±90.3 vs. 109.8±89.1, all P < 0.05). There was no significant difference in the incidence of complications among preoperative IABP support, intra-operative IABP support and post-operative IABP support [3.30% (3/91), 5.46% (10/183), 4.84% (12/248), χ 2 =0.629, P = 0.730]. Bleeding from puncture site occurred in 14 cases (2.68%) without severe bleeding. Limb ischemia occurred in 9 cases (1.72%). One patient (0.19%) was under another surgery because of retroperitoneal hemorrhage caused by vascular injury. One patient (0.19%) was unsuccessful due to a balloon leak. It was shown by logistic regression analysis that presence of age ≥ 65 years [odds ratio (OR) = 2.320, 95% confidence interval (95%CI) = 1.011-1.806, P = 0.047], diabetes mellitus (OR = 2.281, 95%CI = 1.016-5.120, P = 0.026) and combination treatment with ECMO (OR = 4.341, 95%CI = 1.240-15.196, P = 0.040) were found to be the risk factors of complications related to IABP. Conclusions IABP complication rates are generally low. The frequent complications during IABP support is bleeding from site of catheterization and limb ischemia. When patients were treated with IABP, those with older age, diabetes mellitus and combination with ECMO should be monitored closely in order to reduce complications.
