RESUMO
INTRODUCTION: This study aimed to develop the Healthy Eating Report Card for Pre-school Children in Hong Kong for evaluating the prevalence of healthy eating behaviours and favourable family home food environments (FHFEs) among pre-school children in Hong Kong. METHODS: In this cross-sectional study, 538 parent-child dyads from eight kindergartens in Hong Kong were recruited. Parents or guardians completed a questionnaire comprising Report Card items. The Report Card included two indicators of Children's Eating Behaviours (ie, Children's Dietary Patterns and Children's Mealtime Behaviours) and three indicators of FHFEs (ie, Parental Food Choices and Preparation, Avoidance of Unhealthy Foods, and Family Mealtime Environments). Each indicator and its specific items were assigned a letter grade representing the percentage of participants achieving the predefined benchmarks. The grades were defined as A (≥80%, Excellent); B (60%-79%, Good); C (40%-59%, Fair); D (20%-39%, Poor); and F (<20%, Very poor). Plus (+) and minus (-) signs were used to indicate the upper or lower 5% of each grade. RESULTS: Overall, Children's Eating Behaviours were classified as Fair (average grade of 'C'), whereas FHFEs were classified as Good (average grade of 'B'). The sub-grades ranged from 'C' to 'A-', as follows: Children's Dietary Patterns, 'C+'; Children's Mealtime Behaviours, 'C'; Parental Food Choices and Preparation, 'C+'; Avoidance of Unhealthy Foods, 'B'; and Family Mealtime Environments, 'A-'. CONCLUSION: The findings highlight areas for improvement in healthy eating among children. The Healthy Eating Report Card could offer novel insights into intervention tools that promote healthy eating.

Lymph node metastasis status stands as a pivotal prognostic indicator in forecasting the outlook for breast cancer patients. Consequently, precise evaluation of this status holds paramount importance in the staging, treatment, and prognosis of breast cancer. The utilization of radiomics, genomics, proteomics, transcriptomics, and histopathology methodologies has notably enhanced the precision of lymph node metastasis status prediction in breast cancer. This review provides an overview of recent advancements in omics-based lymph node metastasis prediction for breast cancer, elucidating the significance of various omics prediction models and integrated multi-omics models in this predictive endeavor. The overarching goal is to augment the accuracy of preoperative lymph node metastasis status prediction in breast cancer, thereby aiding clinicians in the selection of efficacious personalized treatment strategies, while concurrently averting undertreatment of patients with a heightened risk of metastasis.

Objective: To evaluate the efficacy of chemotherapy and endocrine therapy combined with targeted drugs after progression on cyclin-dependent kinase 4/6 (CDK4/6) inhibitor treatment in hormone receptor (HR) positive/human epidermal growth factor receptor 2 (HER2)-low metastatic breast cancer. Methods: Patients with metastatic breast cancer diagnosed with HR positive/HER2 low expression at the Fifth Medical Center of PLA General Hospital from October 1, 2018 to September 30, 2023 were retrospectively included. All patients received sequential chemotherapy or sequential endocrine therapy combined with targeted drugs after progression on CDK4/6 inhibitor treatment.The median follow-up was 9 months, and the follow-up ended on October 31, 2023. The patients were divided into chemotherapy group (receiving sequential chemotherapy) and endocrine therapy group (receiving sequential endocrine therapy combined with targeted drugs), according to the treatment plan. Information on demographic data, clinical and pathological diagnosis, treatment regimen, and efficacy evaluation was collected. The basic conditions of patients who may affect the curative effect of different treatment schemes were preset as stratified subgroups, including age, progesterone receptor (PR) status, HER2 status, disease-free survival, number of previous endocrine therapy and chemotherapy, and visceral metastasis. The primary endpoint was progression-free survival (PFS), the secondary endpoints were objective response rate (ORR), clinical benefit rate(CBR) and PFS based on stratification factors. The survival curve was plotted by Kaplan-Meier method, the comparison of PFS between groups was performed by log-rank test, and the comparison of ORR and CBR between groups were performed by χ2 test. Results: A total of 188 patients were included, including 126 patients in the chemotherapy group [all females, aged 29-74 (51±10) years] and 62 patients in the endocrine therapy group [1 male and 61 female, aged 29-77 (51±12) years]. ORR of chemotherapy group was 23.0% (29/126), higher than that of endocrine treatment group [3.2% (2/62)] (P<0.001); The CBR of chemotherapy group and endocrine therapy group were 46.8% (59/126) and 33.9% (21/62), respectively, with no statistical significance (P=0.091). The median PFS of chemotherapy group and endocrine therapy group were 5.0 (95%CI: 4.3-5.7) and 4.0 (95%CI: 1.6-6.4) months, respectively, with no statistical significance (P=0.484). In the preset stratified subgroups, the median PFS of chemotherapy [6.0 (95%CI: 5.4-6.6) months] was longer than that of endocrine combined with targeted therapy [2.0 (95%CI: 1.8-2.2) months] (P<0.001) in PR negative patients; In patients who had progressed on over 2 previous endocrine treatments, the median PFS of chemotherapy [5.0 (95%CI: 3.8-6.2) months] was longer than that of endocrine combined with targeted therapy [2.0 (95%CI: 0.6-3.4) months] (P=0.045). Conclusions: After progression on treatment with CDK4/6 inhibitors for HR-positive/HER2-low expression metastatic breast cancer, both chemotherapy and endocrine therpy combined with targeted drugs are viable treatment options. However, for patients with PR negative or ≥2 lines of endocrine therapy previously, priority should be accorded to chemotherapy.

Citrus melanose, caused by the ascomycete fungus Diaporthe citri, is one of the most important diseases in China that affects not only the production but also the quality of citrus. In China, mancozeb is recommended to control melanose disease at the dose of 1.34 g/liter. However, it is widely applied in practice at the dose of 2.66 g/liter or even 4 g/liter, because reduced efficacy of the recommended dose was observed in regions severely damaged by melanose. In this study, some ecofriendly chemicals for melanose management were evaluated. First, the sensitivity to fungicides was screened in the laboratory based on the inhibition of mycelial growth and conidial germination of D. citri. Results showed that both quinone outside inhibitor (QoI) fungicides kresoxim-methyl and trifloxystrobin inhibited conidial germination of D. citri up to 100% at 0.1 µg/ml. The in vivo control efficacy on detached fruit indicated that treatments with elastic nanocopolymer film at 2 g/liter, mancozeb at 1 g/liter, and kresoxim-methyl at 0.1 g/liter significantly inhibited the infection process compared with the control treatment of mineral oil alone. In field trials, the efficacy of kresoxim-methyl at 0.1 g/liter and elastic nanocopolymer film at 2 g/liter mixed with mancozeb at 1 g/liter was equal to that of mancozeb at 2.66 g/liter. The use of mancozeb could be reduced greatly, and the newly developed fungicide combinations are more environmentally friendly due to the low toxicity of both QoI fungicides and elastic nanocopolymer film. The newly developed method with ecofriendly chemicals should play an important role in the management of citrus melanose in the future.

Objective: To explore the application and efficacy of paclitaxel liposome in the treatment of advanced breast cancer among Chinese population in the real world. Methods: The clinical characteristics of patients with advanced breast cancer who received paclitaxel liposome as salvage treatment from January 1, 2016 to August 31, 2019 in 11 hospitals were collected and retrospectively analyzed. The primary outcome was progression free survival (PFS), and the secondary outcome included objective response rate (ORR) and safety. The survival curve was drawn by Kaplan-Meier analysis and the Cox regression model were used for the multivariate analysis. Results: Among 647 patients with advanced breast cancer who received paclitaxel liposome, the first-line treatment accounted for 43.3% (280/647), the second-line treatment accounted for 27.7% (179/647), and the third-line and above treatment accounted for 29.1% (188/647). The median dose of first-line and second-line treatment was 260 mg per cycle, and 240 mg in third line and above treatment. The median period of paclitaxel liposome alone and combined chemotherapy or targeted therapy is 4 cycles and 6 cycles, respectively. In the whole group, 167 patients (25.8%) were treated with paclitaxel liposome combined with capecitabine±trastuzumab (TX±H), 123 patients (19.0%) were treated with paclitaxel liposome alone (T), and 119 patients (18.4%) were treated with paclitaxel liposome combined with platinum ± trastuzumab (TP±H), 108 patients (16.7%) were treated with paclitaxel liposome combined with trastuzumab ± pertuzumab (TH±P). The median PFS of first-line and second-line patients (5.5 and 5.5 months, respectively) were longer than that of patients treated with third line and above (4.9 months, P<0.05); The ORR of the first line, second line, third line and above patients were 46.7%, 36.8% and 28.2%, respectively. Multivariate analysis showed that event-free survival (EFS) and the number of treatment lines were independent prognostic factors for PFS. The common adverse events were myelosuppression, gastrointestinal reactions, hand foot syndrome and abnormal liver function. Conclusion: Paclitaxel liposomes is widely used and has promising efficacy in multi-subtype advanced breast cancer.

Since trastuzumab was listed and approved for breast cancer in 2002, China has entered a new epoch of targeted therapy. Over the past 20 years, anti-human epidermal growth factor receptor 2 (HER2) targeted therapy for breast cancer in China has experienced the era of single-target, tyrosine kinase inhibitors, double-target and anti-HER2 plus antibody-drug conjugate. Advancement in the anti-HER2 targeted therapy is continuously changing the treatment mode of patients with HER2 positive status and even HER2 low expression, significantly improved their prognosis. In the past 20 years, Chinese scholars have participated in international clinical researches, completed a series of registration studies of imported drugs, developed new drugs with proprietary intellectual property rights, enriched the evidence of clinical research on HER2-targeted therapy, and formed a treatment system with both international standards and Chinese characteristics. In particular, the formulation of the Chinese Society of Clinical Oncology Breast Cancer Guidelines and the Chinese expert consensus on anti-HER2 targeted treatment in breast cancer are the concentrated embodiments of Chinese wisdom.

Objective: To examine the feasibility of the modified gasless trans-subclavian approach endoscopic thyroidectomy for lateral neck dissection (LND) in papillary thyroid carcinoma (PTC). Methods: The clinical data of 31 patients with PTC who underwent modified gasless trans-subclavian approach endoscopic LND in the Department of Head and Neck Surgery, Run Run Shaw Hospital, from January to October 2022 were retrospectively analyzed. There were 2 males and 29 females, aged (32.6±8.3) years (range: 17 to 55 years). The maximum diameter of the primary thyroid lesion (M(IQR)) was 1.06 (1.16) cm (range: 0.53 to 2.44 cm), and the maximum diameter of the metastatic lymph node was (1.04±0.37) cm (range: 0.44 to 1.88 cm). Operation time, postoperative hospital stay, number of lymph nodes dissected, and postoperative complications were recorded. Outpatient follow-up was conducted until November 30, 2022. Results: All operations were successfully completed with the endoscopy approach without conversion to open surgery. The operation time was 160 (20) minutes (range: 100 to 215 minutes), and the postoperative hospital stay was 4 (2) days (range: 2 to 14 days). The number of lymph nodes obtained by dissection in the central and lateral compartment of the neck was 11 (12) (range: 0 to 37) and 34.7±14.8 (range: 15 to 69), respectively. Temporary hypoparathyroidism occurred in 4 cases and all recovered within 1 month after the operation. One case suffered from recurrent laryngeal nerve injury (continuing followed up to assess whether it is a temporary injury). The complication of LND included 1 case of chylous leakage that was recovered with conservative treatment, 1 case of Horner syndrome returned to normal 3 months after surgery. During follow-up, there was no residual tumor or recurrence. Conclusion: The modified gasless trans-subclavian approach endoscopic LND for PTC is feasible, with a thorough dissection and concealed incision.

Objectives: To analyze the long-term survival of patients with localized renal cell carcinoma after partical nephrectomy. Methods: The clinicopathological records and survival follow-up data of 2 046 patients with localized renal cell carcinoma, who were treated with partial nephrectomy from August 2001 to February 2021 in the Department of Urology, Sun Yat-sen University Cancer Center, were retrospectively analyzed. There were 1 402 males and 644 females, aged (M(IQR)) 51 (19) years (range: 6 to 86 years). The primary end point of this study was cancer-specific survival. Survival curves were estimated using the Kaplan-Meier method, and the difference test was performed by Log-rank test. Univariate and multivariate Cox analysis were fitted to determine factors associated with cancer-specific survival. Results: The follow-up time was 49.2 (48.0) months (range: 1 to 229 months), with 1 974 patients surviving and 72 dying. The median cancer-specific survival time has not yet been reached. The 5- and 10-year cancer specific survival rates were 97.0% and 91.2%, respectively. The 10-year cancer-specific survival rates for stage pT1a (n=1 447), pT1b (n=523) and pT2 (n=58) were 95.3%, 81.8%, and 81.7%, respectively. The 10-year cancer-specific survival rates of patients with nuclear grade 1 (n=226), 2 (n=1 244) and 3 to 4 (n=278) were 96.6%, 89.4%, and 85.5%, respectively. There were no significant differences in 5-year cancer-specific survival rates among patients underwent open, laparoscopic, or robotic surgery (96.7% vs. 97.1% vs. 97.5%, P=0.600). Multivariate analysis showed that age≥50 years (HR=3.93, 95%CI: 1.82 to 8.47, P<0.01), T stage (T1b vs. T1a: HR=3.31, 95%CI: 1.83 to 5.99, P<0.01; T2+T3 vs. T1a: HR=2.88, 95%CI: 1.00 to 8.28, P=0.049) and nuclear grade (G3 to 4 vs. G1: HR=2.81, 95%CI: 1.01 to 7.82, P=0.048) were independent prognostic factors of localized renal cell carcinoma after partial nephrectomy. Conclusions: The long-term cancer-specific survival rates of patients with localized renal cancer after partial nephrectomy are satisfactory. The type of operation (open, laparoscopic, or robotic) has no significant effect on survival. However, patients with older age, higher nuclear grade, and higher T stage have a lower cancer-specific survival rate. Grasping surgical indications, attaching importance to preoperative evaluation, perioperative management, and postoperative follow-up, could benefit achieving satisfactory long-term survival.
RESUMO
Objective: To explore the independent risk factors of internal mammary lymph nodes (IMN) metastasis and the risk assessment method of IMN metastasis preoperatively in breast cancer patients with negative IMN in imaging examination, and guide the radiotherapy of IMN in patients with different risk stratification of IMN metastasis. Methods: The clinical and pathological data of 301 breast cancer patients who underwent internal mammary sentinel node biopsy(IM-SLNB) and/or IMN dissection in Shandong Cancer Hospital with negative IMN on CT and/or MRI from January 2010 to October 2019 were analyzed retrospectively. The independent risk factors were analyzed by univariate and multivariate logistic regression, and the independent risk factors of IMN metastasis were used to risk stratification. Results: Among the 301 patients, 43 patients had IMN metastasis, and the rate of IMN metastasis was 14.3%. Univariate analysis showed that vascular tumor thrombus, progesterone receptor (PR) expression, T stage and N stage were associated with IMN metastasis. Multivariate logistic regression analysis showed that tumor located in medial quadrant, positive PR and axillary lymph node metastasis were independent risk factors for IMN metastasis. The risk of IMN metastasis was assessed according to the independent risk factors of the patients: low-risk group is including 0 risk factor, medium-risk group is including 1 risk factor, and high-risk group is including 2-3 risk factors. According to this evaluation criteria, 301 patients with breast cancer were divided into low-risk group (with 0 risk factors), medium-risk group (with 1 risk factor) and high-risk group (with 2-3 risk factors). The IMN metastasis rates were 0 (0/34), 4.3% (6/140) and 29.1% (37/127), respectively. Conclusions: The risk stratification of IMN metastasis according to three independent risk factors of IMN metastasis including tumor located in medial quadrant, positive PR and axillary lymph node metastasis in breast cancer patients can guide the radiotherapy of IMN in newly diagnosed breast cancer patients. For N1 patients, radiotherapy of IMN is strongly recommended when the primary tumor is located in the medial quadrant and/or PR positive.

Objective: To investigate the characteristics of delayed high-degree atrioventricular block (DHAVB) after transcatheter aortic valve replacement (TAVR). Methods: One hundred and seventy-six patients who underwent TAVR with a self-extending valve between May 2014 and November 2018 in the Department of Cardiology, West China Hospital of Sichuan University, were retrospectively enrolled, including 101 males and 75 females, aged 54-92 (73±7) years, and the data were collected during the perioperative and 30 d follow-up periods. According to the occurrence of HAVB after TAVR, 160 patients were divided into no-HAVB group (145 cases) and DHAVB group (15 cases), except 16 patients who developed HAVB within 2 days after TAVR. Baseline data, intraoperative data, and immediate postoperative ECG characteristics were compared between the two groups, and logistic regression models were used to analyze the factors associated with the occurrence of DHAVB after TAVR. Meanwhile, the diagnostic ability of the postoperative routine 12-lead ECG for DHAVB was evaluated using the ambulatory ECG findings as the standard diagnosis. Results: The incidence of DHAVB was 8.5% (15/176) and occurred at 5 (4, 6) d. Compared with the no-HAVB group. The percentage of no new conduction block on the immediate postoperative ECG was lower in the DHAVB group [6/15 vs 66.2%(96/145), P=0.044], and the percentage of new right bundle branch block on the immediate postoperative ECG was higher [4/15 vs 3.4%(5/145), P=0.002]. Multifactorial logistic regression analysis showed that right bundle branch block on the immediate postoperative ECG [OR (95%CI):6.60 (1.26-34.47), P=0.025] was an associated factor for the development of DHAVB after TAVR. The specificity of postoperative routine 12-lead ECG for the diagnosis of DHAVB was 100% (145/145), but the sensitivity was only 73.3% (11/15). Conclusions: The incidence of DHAVB after TAVR is also high in Chinese. The immediate postoperative ECG characteristics of patients who underwent TAVR are associated with DHAVB events, and applying these characteristics to risk stratify patients may optimize the management of DHAVB after TAVR.

With the development of new strategies like target therapy and immunotherapy, early breast cancer treatment has become more standardized, and the interval of disease free survival has been extended. Although guidelines and expert consensus have provided supports for clinical decision making, there are still some controversial issues in clinical practice, attributing to different treatment concepts, product indications and accessibility. These controversial issues would eventually affect the treatment of early breast cancer. This year in 2021, the approval of new indications of drugs like abemaciclib and the popularity of dual anti-human epidermal growth factor receptor 2 targeted drugs have promoted the change of treatment modalities for different types of early breast cancer. To this end, ten hot topics of early breast cancer are summarized according to their different molecular typing and treatment stages for discussion.

Objective: To examine the safety and feasibility of gasless submental-transoral combined appoach endoscopic thyroidectomy for papillary thyroid carcinoma (PTC). Methods: A retrospective analysis of the clinical data of 41 patients with PTC who underwent the gasless submental-transoral combined appoach endoscopic thyroidectomy at the Department of Head and Neck Surgery, Sir Run Run Shaw Hospital, Zhejiang University School of Medicine from November 2020 to April 2021. There were 5 males and 36 females with the age of (35.0±8.7) years (range: 19 to 58 years). A horizontal incision with a length of 2.0 cm is made under the chin as an observation hole, a 10 mm Trocar and a self-developed retractor are inserted, and two 5 mm longitudinal incisions are made on the labial side in the vestibule of the oral cavity as an operation hole, each inserting a 5 mm Trocar, the operation direction is from the cranial side to the caudal side. The sensation of the lower lip and chin was measured on the first day and one month postoperative. The operation time, hospital stay, the number of lymph nodes dissected and postoperative complications were recorded. Results: Surgical procedures in all cases were successfully completed under endoscopic approach without transfering to open surgery. The operation time was (99±34) minutes (range: 50 to 180 minutes) and the postoperative hospital stay was (3.4±2.2) days (range: 2 to 16 days). The maximum diameter of PTC was (7.6±5.8) mm (range: 2 to 30 mm), and the number of lymph nodes of the central compartment dissection was 6(5) (M(IQR)) (range: 1 to 25). The duration of follow-up is 1 month after operation, and the follow-up method is adopted in outpatient clinic. Postoperation complications included 2 cases of transient hypoparathyroidism, One case of recurrent laryngeal nerve injury (continue to follow up to assess whether it is a temporary injury). Postoperative minor chyle leak, seroma, and local redness and swelling in 1 case each were cured after conservative treatment. 1 case of transient minor numbness of the lower lip was observed. No permanent hypoparathyroidism, postoperative bleeding and numbness of the chin was observed. Conclusion: The gasless submental-transoral combined appoach endoscopic thyroidectomy is a feasible approach in selected PTC patients and has clinical application value.

Objectives: To examine the landscape and metastases of the lymph nodes in prostatic anterior fat pad (PAFP) at radical prostatectomy (RP), and to describe the clinical characteristic of the patients with lymph node metastases in PAFP. Methods: The clinical and pathological data of 287 prostate cancer patients underwent RP from December 2019 to August 2021 in Department of Urology, Sun Yat-sen University Cancer Center were collected and analyzed retrospectively. All patients were male, aging (66±7) years (range: 42 to 83 years). The preoperative prostate-specific antigen (PSA) (M(IQR)) were 16.00(29.64) µg/L (range: 0.01 to 99.90 µg/L). There were 244 patients with localized or locally advanced prostate cancer and 43 patients with metastatic prostate cancer. All PAFP were dissected at RP routinely and were sent for pathologic analysis respectively. The PAFP was dissected from the prostate apex caudally toward the bladder neck and dissection extended to the joint of the prostate and the endopelvic fascia bilaterally. All the specimen of PAFP were examined and reported by subspecialty pathologists of genitourinary tumors. Statistical analysis was performed by Student t test, Wilcoxon rank-sum test, χ2 test or Fisher exact test. Results: There were 8.0% (23/287) patients with lymph nodes in PAFP, 3.8% (11/287) patients with PAFP lymph node metastases. Pathologically upstaged occurred in 1 patient due to the PAFP lymph node as the solitary metastatic lesion. Patients with lymph node metastases in PAFP presented higher preoperative PSA (M(IQR): 48.2(73.0) µg/L vs. 15.4(26.5) µg/L, Z=3.158, P=0.002), clinical T stage and N stage (Z=2.977, P=0.003; Z=2.780, P=0.005) and preoperative Gleason score (Z=2.205, P=0.027). Conclusions: Routine dissection of PAFP at RP and separately pathological analysis may allow more lymph nodes and lymph node metastases detection. More accurate pathological N stage may be acquired and consequently may improve the survival of patients by offering more appropriate adjuvant or salvage therapy.

Objective: To evaluate the safety and effectiveness of a new Chinese-made surgical biopatch for atrial septum under the establishment of atrial septal defect animal model in miniature pigs. Methods: From June 2018 to April 2019, 26 pigs were divided into experimental group (15 pigs) and the control group (11 pigs). Animal models of atrial septal defect were established by traditional surgical methods. The to-be-evaluated and listed surgical biological patches (with a diameter of 10 mm) were implanted in the experimental group and the control group to repair the atrial septal defect. Cardiac ultrasound and blood examination of all animals were performed before and at 7, 30, 90, 180 days after operation, the results were analyzed with repetitive measurement and analysis of variance. At 90 days and 180 days after the operation, tissue samples were taken from animals after euthanasia. Pathological examination of heart and major organs were conducted. The independent sample t test and rank sum test were used to compare the data between the two groups, and the nonparametric was used to compare the patch calcification score between the two groups. Results: In total of 26 animals, 14 animals in the experimental group(6 at 90 days, 8 at 180 days) and 9 animals in the control group(4 at 90 days, 5 at 180 days) reached the end of the experiment. The other 3 animals (1 in the experimental group and 2 in the control group) died of arrhythmia, whole heart failure and right heart failure, the results of pathological examination showed that the causes of death were unrelated to the experimental materials. Cardiac ultrasound showed no patch leakage in all animals. There was no statistically significant difference in cardiac ultrasound and blood examination between the two groups at different time points after operation (all P>0.05). The pathological results showed that all the implants were intact and had good biocompatibility. There was no significant difference in the mean endothelialization rate between the experimental group and the control group at 90 and 180 days after operation ((80.8±29.1)% vs. (82.5±23.6)%, t=0.095, P=0.927; (78.8±36.4)% vs. (82.0±19.2)%, t=0.182, P=0.859) on 90 and 180 days, there was no significant difference in the patch calcification score between the two groups (1.00(1.25) vs. 2.00(0.75), Z=6.500, P=0.214; 0(0.75) vs. 1.00(2.00), Z=12.000, P=0.139). Conclusion: The new Chinese-made surgical biopatch for atrial septum has comparable safety and efficacy to that of the marketable patch in miniature pig atrial septal defect animal model.

In the past two decades, with the introduction of NCCN guidelines, the establishment of a standardized diagnosis and treatment system for breast cancer had begun. The Chinese version of the NCCN guidelines, which combines international standards and Chinese characteristics, was then developed to guide clinical practice. Since 2011, Chinese experts have entered St. Gallen International Expert Consensus Group, and to introduce the latest therapy concepts. On this basis, the Chinese Society of Clinical Oncology has developed guidelines for diagnosis and treatment in line with product accessibility and expert opinions to help clinicians choose the best treatment option. The latest Chinese Society of Clinical Oncology Breast Cancer Guideline will further contribute to the establishment of a standardized diagnosis and treatment system for breast cancer.

Internal mammary lymph node (IMLN) metastasis forms the part of the N-staging of breast cancer, and affects the treatment program and prognosis. At present, IMLN metastasis is clinically diagnosed by anatomical imaging, functional imaging and postoperative pathology. Anatomical imaging includes ultrasound, CT and MRI. Functional image includes positron emission computed tomography (PET-CT), PET-MRI, single photon emission computed tomography (SPECT) and SPECT-CT. Because of the special location of the internal mammary region and the complex anatomical structure around it, the imaging diagnosis rate and pathological diagnosis rate of IMLN are often different. Therefore, it is important to identify the relevant factors of IMLN metastasis for guiding the local treatment of internal mammary region, including the scope of surgery and radiotherapy.

Objective: To explore the improvement rate of liver fibrosis in patients with chronic hepatitis B virus infection who received entecavir alone or in combination with anluohuaxianwan for 78 weeks. Methods: Patients with chronic HBV infection were randomly treated with entecavir alone or in combination with anluohuaxian for 78 weeks. Ishak fibrosis score was used for blind interpretation of liver biopsy specimens. The improvement in liver fibrosis condition before and after the treatment was compared. Student's t test and non-parametric test (Mann-Whitney U-Test and Kruskal-Wallis test) were used to analyze the measurement data. The categorical variables were analyzed by Chi-square test method and Spearman's rank correlation coefficient was used to test bivariate associations. Results: Liver fibrosis improvement rate after 78 weeks of treatment was 36.53% (80/219) and the progression rate was 23.29% (51/219). The improvement of liver fibrosis was associated to the degree of baseline fibrosis and treatment methods (P < 0.05). The improvement rate of hepatic fibrosis in patients treated with anluohuaxianwan combined with entecavir at baseline F < 3 (54.74%, 52/95) was significantly higher than that in patients treated only with entecavir (33.33%, 16/48), P = 0.016 and the progression rate of hepatic fibrosis (13.68%, 13/95) was lower than that in patients treated alone (18.75%, 9/48), P = 0.466. In patients with baseline F < 3, the proportion of patients with improved and stable liver fibrosis in the combined treatment group (68.1%, 32/47) was higher than that in the treatment group alone (51.7%, 15/29). Conclusion: Combined anluohuaxianwan and entecavir treatment can significantly improve the improvement rate of liver fibrosis in patients with chronic hepatitis B virus infection. Furthermore, it has the tendency to improve the stability rate and reduce the rate of progression of liver fibrosis.

OBJECTIVES: To analyze the causes of perinatal death and related factors from the perspective of forensic medicine, and to provide references for reducing perinatal mortality and guidance for forensic identification. METHODS: A retrospective analysis was performed on 102 cases of perinatal autopsy with clinical data from the Department of Forensic Medicine of Chongqing Medical University in 2004-2016. RESULTS: Of the 102 cases of perinatal deaths, 66 ï¼64.71%ï¼ were neonatal deaths, 24 ï¼23.53%ï¼ were stillborn foetuses, and 12 ï¼11.76%ï¼ were stillbirths. Among the 66 neonatal death cases, 39 ï¼59.09%ï¼ died within 1 d, 19 ï¼28.79%ï¼ died within 1-3 d, and 8 ï¼12.12%ï¼ died within >3-7 d of birth. The top 3 causes of neonatal death were pulmonary diseases, congenital malformation, umbilical cord and placental abnormalities. The causes of stillborn foetus and stillbirth were mainly umbilical cord and placental abnormalities, and intrauterine asphyxia. CONCLUSIONS: Pulmonary diseases, umbilical cord and placental abnormalities, and congenital malformations are the main causes of perinatal death. In order to reduce the perinatal mortality, pre-pregnancy examination and prenatal care should be strengthened, and the knowledge of pregnancy care should be popularized.
