Cervical chylous leakage is rare after central lymph node dissection for thyroid cancer, and the coexistence of chylothorax is even more uncommon. This article reports a case of a 39-year-old female patient who underwent total thyroidectomy and left central lymph node dissection for papillary thyroid carcinoma complicated by follicular adenoma. On the second postoperative day, the patient developed white, milky drainage from the neck, suggesting chylous leakage, and experienced mild chest tightness, cough, and low-grade fever. Chest CT revealed bilateral pleural effusion, with the left side being more severe. On the third day, ultrasound-guided left-sided pleural puncture and drainage were performed and hydrothorax triglycerides and total cholesterol levels were measured, chylothorax were diagnosed as a result.After conservative treatment including a low-fat diet, fasting, nutritional support, neck pressure dressing and negative pressure suctionand closed chest drainage, the patient's condition improved rapidly. The patient was discharged on the 8th postoperative day with full recovery. No recurrence has been observed during follow-up to date.

BACKGROUND: The purpose of this study was to evaluate the safety and efficacy of subsequent radiotherapy (RT) following first-line treatment with durvalumab plus chemotherapy in patients with extensive-stage small cell lung cancer (ES-SCLC). METHODS: A total of 122 patients with ES-SCLC from three hospitals during July 2019 to December 2021 were retrospectively analyzed. Inverse probability of treatment weighting (IPTW) analysis was performed to address potential confounding factors. The primary focus of our evaluation was to assess the impact of RT on progression-free survival (PFS) and overall survival (OS). RESULTS: After IPTW analysis, 49 patients received durvalumab plus platinum-etoposide (EP) chemotherapy followed by RT (Durva + EP + RT) and 72 patients received immunochemotherapy (Durva + EP). The median OS was 17.2 months vs . 12.3 months (hazard ratio [HR]: 0.38, 95% confidence interval [CI]: 0.17-0.85, P = 0.020), and the median PFS was 8.9 months vs . 5.9 months (HR: 0.56, 95% CI: 0.32-0.97, P = 0.030) in Durva + EP + RT and Durva + EP groups, respectively. Thoracic radiation therapy (TRT) resulted in longer OS (17.2 months vs . 14.7 months) and PFS (9.1 months vs . 7.2 months) compared to RT directed to other metastatic sites. Among patients with oligo-metastasis, RT also showed significant benefits, with a median OS of 17.4 months vs . 13.7 months and median PFS of 9.8 months vs . 5.9 months compared to no RT. Continuous durvalumab treatment beyond progression (TBP) prolonged OS compared to patients without TBP, in both the Durva + EP + RT (NA vs . 15.8 months, HR: 0.48, 95% CI: 0.14-1.63, P = 0.238) and Durva + EP groups (12.3 months vs . 4.3 months, HR: 0.29, 95% CI: 0.10-0.81, P = 0.018). Grade 3 or 4 adverse events occurred in 13 (26.5%) and 13 (18.1%) patients, respectively, in the two groups; pneumonitis was mostly low-grade. CONCLUSION Addition of RT after first-line immunochemotherapy significantly improved survival outcomes with manageable toxicity in ES-SCLC.

Objective:To investigate the risk factors of hypoparathyroidism (HPT) and hypocalcemia in patients undergoing total thyroidectomy (TT), and to explore the changes of parathyroid hormone and blood calcium after TT.Methods:The clinical data of 101 patients undergoing TT from November 2018 to September 2022 in the First Hospital of Hebei Medical University were retrospectively analyzed. The basic clinical data were recorded. The blood calcium and parathyroid hormone levels were measured before surgery and 1 d, 1 week after surgery. The occurrence of postoperative hypocalcemia was recorded. According to postoperative parathyroid hormone level, the patients were divided into control group (normal parathyroid function) and HPT group (reduced parathyroid hormone level). The patients with postoperative hypocalcemia symptoms were classified as the hypocalcemia symptoms group, and the patients without postoperative hypocalcemia symptoms were classified as the non-hypocalcemia symptoms group. Multivariate Logistic regression was used to analyze the independent risk factors of HPT and hypocalcemia in TT patients.Results:The postoperative parathyroid hormone level decreased in 41 cases (HPT group) and normal in 60 cases (control group). There were 24 patients with postoperative hypocalcemia symptoms (hypocalcemia symptoms group) and 77 patients without postoperative hypocalcemia symptoms (non-hypocalcemia symptoms group). The rate of using bipolar electric coagulation forceps in HPT group was significantly lower than that in control group: 31.71% (13/41) vs. 76.67% (46/60), while the rate of central lymph node dissection was significantly higher than that in control group: 82.93% (34/41) vs. 60.00% (36/60), and there were statistical differences ( P<0.01 and <0.05). Multivariate Logistic regression analysis result showed that TT combined with unilateral or bilateral central lymph node dissection was an independent risk factor for HPT in TT patients ( OR = 1.706 and 1.501, 95% CI 1.019 to 2.856 and 1.052 to 2.140, P<0.05). The preoperative serum calcium, postoperative serum calcium and postoperative parathyroid hormone in hypocalcemia symptoms group were significantly lower than those in hypocalcemia symptoms group: (2.32 ± 0.11) mmol/L vs. (2.37 ± 0.11) mmol/L, (2.16 ± 0.21) mmol/L vs. (2.25 ± 0.18) mmol/L and 3.00 (1.00, 5.45) ng/L vs. 19.90 (8.50, 33.80) ng/L, and there were statistical differences ( P<0.05 or <0.01). Multivariate Logistic regression analysis result showed that postoperative parathyroid hormone was an independent risk factor of hypocalcemia symptoms in TT patients ( OR = 0.927, 95% CI 0.883 to 0.974, P<0.01). In patients with HPT, the blood calcium at 1 week after surgery was significantly lower than that at 1 d after surgery: (2.07 ± 0.19) mmol/L vs. (2.17 ± 0.25) mmol/L, and there was statistical difference ( t = 2.05, P<0.05); the parathyroid hormone at 1 week after surgery was significantly higher than that at 1 d after surgery: 8.30 (3.55, 19.55) ng/L vs. 3.60 (1.00, 6.85) ng/L, and there was statistical difference ( Z = - 3.78, P<0.01). Conclusions:When performing TT, standardizing the surgical techniques, reducing unnecessary central lymph node dissection, and using bipolar electric coagulation forceps as much as possible can help to reduce the occurrence of postoperative HPT. The levels of postoperative parathyroid hormone and blood calcium should be promptly detected, the change of both should be given attention, and do a good job in preventing and treating hypocalcemia.

AIM:To test and compare the perceptual eye position and fixation stability of adolescents with emmetropia and adolescents with low myopia, investigating the characteristics of the perceptual eye position and fixation stability of adolescents with low myopia.METHODS: Cross-sectional study. A total of 132 adolescents(264 eyes)who visited in the ophthalmology clinic of our hospital from April to December 2023 were randomly selected as the research subjects. Participants were categorized into normal control group(n=45, 90 eyes), simple low myopia group(n=45, 90 eyes)and low myopia with anisometropia group(n=42, 84 eyes)according to their refractive status and were underwent assessments for perceptual eye position and fixation stability.RESULTS: Compared with the normal control group, the static and dynamic horizontal perceptual eye position deviation of the simple low myopia group and the low myopia with anisometropia group were significantly increased(P<0.05). Compared with the simple low myopia group, the static and dynamic horizontal perceptual eye position deviation of the low myopia with anisometropia group were significantly increased(P<0.05). There was no significant difference in static and dynamic vertical perceptual eye position deviation among the three groups(P>0.05); compared with the normal control group, the horizontal and vertical fixation stability of the simple low myopia group and the low myopia with anisometropia group were significantly worse(all P<0.01), but there was no differences in the simple low myopia group and the low myopia with anisometropia group(P >0.05).CONCLUSION: Abnormalities are observed in perceptual eye position and fixation stability function in adolescents with low myopia compared with those adolescents with emmetropia, even at best corrected visual acuity. The occurrence of anisometropia could lead to an increased degree of horizontal perceptual eye position displacement.

Objective:To investigate the clinical characteristics, diagnosis and treatment of dermatomyositis with kidney neoplasm.Methods:The data of two patients with dermatomyositis complicated with kidney neoplasm in Tongji Hospital from January to February 2022 were retrospectively analyzed. The first case was a 55-year-old female, who was admitted with the chief complaints of recurrent erythema of upper extremities for 2 months and facial erythema for 1 month. Physical examination: erythema can be seen on upper limbs and face, no tenderness or percussion pain in kidney area. Myositis enzyme profile test showed that anti-Mi-2 antibody and anti-SSA /Ro-52 antibody were positive. Contrast CT showed nodular uneven enhancement in the right kidney with a size of 50 mm×41 mm. The second case was a 58-year-old female, who was admitted with the chief complaints of kidney occupying for a month. Physical examination: flaky erythema on face, no tenderness or percussion pain in kidney area. Myositis enzyme profile test showed that anti-Ro-52 antibody and anti-MDA5 antibody were positive. Contrast CT showed a significantly uneven enhanced mass with a size of about 50 mm×41 mm on left kidney. Both patients were diagnosed with kidney neoplasm before surgery and underwent laparoscopic partial nephrectomy in Tongji Hospital.Results:Both patients received regular oral prednisone after surgery. The pathological presentation of case 1 was papillary renal cell carcinoma, the facial erythema subsided 1 month after surgery, and there was no tumor recurrence for 13 months. The pathological presentation of case 2 was clear cell renal cell carcinoma, facial erythema subsided 2 weeks after surgery, and there was no tumor recurrence for 12 months.Conclusions:The diagnosis of dermatomyositis should be combined with clinical manifestations and laboratory examination, and the possibility of malignant tumor should be excluded due to the high likelihood of concomitant malignancy. For patients with dermatomyositis with kidney neoplasm, the main treatment is still surgery, and supplemented with glucocorticoid therapy.

Objective:To explore the effect of postoperative coping style on marital quality and spouse post-traumatic growth in breast cancer patients.Methods:A total of 80 breast cancer patients who underwent radical mastectomy and chemotherapy in Department of Breast Surgery in Tongling Maternal and Child Health Hospital from January 2016 to June 2021 were selected and they were followed up for 0.5 to 1.0 year. Medical Coping Modes Questionnaire (MCMQ) , Olson Marital Quality Questionnaire (ENRICH) and Posttraumatic Growth Inventory (PTGI) were used to investigate patients and their spouses. A total of 80 questionnaires were distributed and 80 valid questionnaires were recovered, with an effective recovery rate of 100%. The correlations among medical coping, marital quality and spouse's post-traumatic growth in 80 breast cancer patients were analyzed.Results:ENRICH score and PTGI score of spouse in 80 breast cancer patients were positively correlated with the face dimension score of MCMQ ( r=0.549-0.693, P<0.05) , and negatively correlated with the avoidance and yield dimension score ( r=-0.256--0.391, P<0.05) . In the mediating effect model, the regression coefficients of multiple linear regression analysis were all significant ( P<0.05) . The indirect effects of facing, avoiding and yielding coping styles on spouse's post-traumatic growth and marital quality were 0.382, 0.183 and 0.079 (95% CI did not include 0) , and the relative effects were 47.04%, 22.54%, and 9.73%, respectively. Conclusions:Face is the main coping style of breast cancer patients after surgery. The face coping style is not only positively correlated with the quality of marriage and the level of post-traumatic growth of spouse, but also plays a mediating effect between them. For spouses of patients with poor post-traumatic growth level, the quality of marriage can be improved by improving the level of post-traumatic growth of patients' spouses and the coping ability of patients.

In order to explore the treatment of Her-2 positive breast cancer patients who failed in multi-line treatments, we retrospectively analyzed the clinical data of a patient with refractory Her-2 positive breast cancer.The patient was initially diagnosed as Her-2 positive advanced breast cancer.After six line treatment in the outer hospital, the patient′s condition was basically in a progressive state.The breast tumor was broken and purulent, the lung metastasis increased, and the patient′s quality of life was poor.The patient was admitted to Department of Breast Surgery of Affiliated Suqian Hospital of Xuzhou Medical University, after MDT discussion, we gave pyrrolotinib combined with capecitabine treatment, the chest wound healed gradually, the lung metastasis gradually reduced, and the quality of life was better.A retrospective analysis of this case showed that pyrrolidine combined with capecitabine may bring hope to Her-2 positive breast cancer patients who failed to receive multi-line therapies, especially those who failed to target therapy.

Objective To evaluate the nutritional value of yeast protein, and to provide laboratory evidence for its application in the field of food and health food. Methods The amino acids content of yeast protein, soybean protein, whey protein and mixed protein was detected. Five nutritional evaluation methods, including amino acid score, ratio of total essential amino acid, ratio coefficient of amino acid, Pearson's correlation coefficient, and equally weighted gray correlation analysis were used to evaluate the protein quality. The protein efficacy test of the four proteins was performed in Sprague-Dawley rats to compare their nutritional value in vivo. Results The results showed that yeast protein was rich in essential amino acids, accounting for 47.58% of the total amino acids, and the ratio of essential amino acids to non-essential amino acids reached 0.91. Five nutritional evaluation methods all revealed that the yeast protein was an excellent protein in quality. The results of the protein efficacy test showed that yeast protein was able to promote the growth and development of the animals, and keep them in good nutritional condition, which was similar to whey protein, soy protein, and casein. The mixed protein had the highest corrected efficiency ratio among all the proteins tested in this study, possibly because the mixed ingredients made the amino acids complementary and thus had higher nutritional value. Conclusion Yeast protein can be used as a useful supplement to plant-derived and animal-derived protein products.
