OBJECTIVE To analyse the prognosis and laryngeal function retention of patients undergoing minimally invasive and open surgery after induction chemotherapy.METHODS The clinical data of 54 hypopharyngeal carcinoma patients who received induction chemotherapy and underwent laryngeal preservation surgery in Beijing Tongren Hospital from 2016 to 2022 were retrospectively analyzed.The laryngeal function recovery and survival rate were compared between the two groups.RESULTS Twenty-eight patients underwent transoral minimally invasive surgery and 26 patients underwent partial laryngectomy and/or partial laryngectomy via external cervical approach.The 3-year survival rates of the two groups were 63%and 59%,respectively,and the difference was not statistically significant(P＞0.05).The differences were statistically significant(P＜0.05).CONCLUSION In patients with downstaged hypopharyngeal carcinoma after induction chemotherapy,the survival rate of transoral minimally invasive surgery is similar to that of open surgery,and the laryngeal function recovery of transoral minimally invasive surgery is better.

Objective To observe the clinical efficacy of She medicine Huoxue Jiangya Tie combined with external counterpulsation on patients with type H grade 1 hypertension with blood stasis syndrome.Methods A total of 64 patients with type H grade 1 hypertension with blood stasis syndrome were selected from Lishui Hospital of Traditional Chinese Medicine from January 2022 to December 2023.According to the principle of random control,they were divided into control group(western medicine+external counterpulsation)and observation group(She medicine Huoxue Jiangya Tie+western medicine+external counterpulsationon),with 32 cases in each group,the duration of treatment was 8 weeks.The difference on clinical efficacy between two groups,traditional Chinese medicine syndrome scores,clinical systolic blood pressure(CSBP),clinical diastolic blood pressure(CDBP),brachial-ankle pulse wave velocity(baPWV),ankle brachial index(ABI),renin,aldosterone(ALD),angiotensin Ⅱ(Ang Ⅱ),homocysteine(Hcy)before and after treatment,between two groups were compared,and recorded adverse reactions.Results After 8 weeks of treatment,the total effective rate of blood pressure reduction in observation group(93.75％)was better than that in control group(75.00％)(P＜0.05);And the traditional Chinese medicine syndrome score of observation group was lower than that of control group,with a statistically significant difference(P＜0.05);The CSBP,CDBP,and baPWV of both groups of patients decreased compared to before treatment,and observation group was lower than control group(P＜0.05);The ABI of both groups significantly increased compared to treatment,and observation group was higher than control group(P＜0.05);The levels of renin,ALD,Ang Ⅱ,and Hcy in both groups decreased compared to before treatment,and observation group was lower than control group(P＜0.05);Both groups of patients did not experience serious adverse reactions.Conclusion She medicine Huoxue Jiangya Tie combined with external counterpulsation in the treatment of type H grade 1 hypertension patients with blood stasis syndrome can better alleviate clinical symptoms,reduce blood pressure,renin,ALD,AngⅡ and Hcy levels,and reduce arteriosclerosis stiffness,which is worthy of clinical application.

Objective:To summarize the clinical manifestations and molecular genetic characteristics of 5 families with maturity-onset diabetes mellitus of the young 2 (MODY2) caused by glucokinase (GCK) gene mutations.Methods:Clinical data and biochemical results of probands were collected. Peripheral blood samples of probands and first-degree family members were collected and whole exome gene was detected using second-generation sequencing. After comparing against the database, the suspected pathogenic sites were selected for Sanger sequencing verification.Results:All the 5 probands presented with mild fasting hyperglycemia, HbA 1C<7.5%, and no symptoms of thirst, polydipsia or polyuria. There were 6 mutants in 5 families, including M1: c.555delT (P.leu186CysFS Ter19) and M3: c. 263T>A (p.Met88Lys) which haven′t been reported before. During the follow-up, all probands received life-style intervention, except 2 pregnant women who should consider insulin treatment if necessary according to fetal genotypes. Conclusion:Among patients who meet the diagnostic criteria for MODY, MODY2 screening should be performed for children or pregnant women with mild hyperglycemia and family history. GCK gene detection is the gold standard for diagnosis, and accurate diagnosis will be conducive to the selection of appropriate treatment.

Objective:To summarize the experience of surgical methods without repairing the fistula for 92 cases with gastrointestinal intrathoracic fistula.Methods:The surgical methods without repairing the fistula were performed through VATS, small incision assisted with VATS or thoracotomy. The focus of the surgery was to promote lung expansion, eliminate the residual cavity of chest cavity and keep effective drainage. After entering the chest cavity from the affected side, wash chest cavity with a large amount of warm normal saline and sterilize intermittently with iodophor to ensure the sterile environment in the pus cavity. Then completely remove the pleural cellulose or fiberboard on visceral pleura to promote lung expansion, eliminate the residual cavity of the chest cavity. The fistula was covered tightly and supported firmly by the visceral pleura on the lung. Multiple T-tubes were placed in thoracic cavity and fistula to keep effective postoperative drainage.Results:Among 92 cases, 85 cases were cured and the cure rate was 92.4% (85/92).7 cases died and the mortality rate was 7.61% (7/92). The 7 dead cases include 5 cases with esophagogastric anastomotic fistula (the death of 3 cases was cause by aortic esophagogastric fistula, the death of 1 case was cause by thoracic gastric tracheal fistula and 1 case was dead because of pulmonary infection and respiratory failure), 1 case with esophageal rupture (the cause of death was septic shock ), and 1 case with esophageal perforation(the cause of death was pulmonary infection and respiratory failure).Conclusion:Most of the surgeries without repairing gastrointestinal intrathoracic fistula are conducted simply through VATS or small incision assisted with VATS., which is safe and effective.

Objective:To investigate the value of high-frequency ultrasound and shear wave elastography in preoperative evaluation of basal cell carcinoma (BCC) .Methods:A total of 95 patients with histopathologically confirmed cutaneous BCC were enrolled from Department of Dermatology, Hospital of Traditional Chinese Medicine of Zhongshan from January 2017 to December 2020, all of whom had underwent preoperative conventional ultrasonography and shear wave elastography. Conventional ultrasonography parametres including the maximum diameter, maximum infiltration depth, maximum blood flow velocity and resistance index were recorded, so were shear wave elastography parametres including the average Young′s modulus (Eave) , Young′s modulus standard deviation (Esd) and average Young′s modulus ratio (Eratio) . All the patients were divided into high- and low-risk BCC groups according to pathologic subtypes. Paired t-test was used to compare conventional ultrasonography and shear wave elastography findings between the 2 groups. Results:There were 15 cases in the high-risk BCC group and 80 cases in the low-risk BCC group. Compared with the low-risk BCC group, the high-risk BCC group showed significantly increased maximum depth of tumor infiltration (8.5 ± 4.6 mm vs. 4.5 ± 1.6 mm, t = 6.150, P < 0.001) , Eave (32.7 ± 11.2 kPa vs. 20.6 ± 5.1 kPa, t = 4.065, P = 0.001) and Esd (7.0 ± 4.1 kPa vs. 4.2 ± 2.1 kPa, t = 2.632, P = 0.018) , while there were no significant differences in the other measurement data between the two groups (all P > 0.05) . The areas under the receiver operating characteristic curves of the maximum infiltration depth, Eave and Esd for the diagnosis of high-risk BCC were 0.775, 0.909 and 0.822 respectively, and Eave showed the best diagnostic performance. Using 25.7 kPa as the cut-off value, the sensitivity and specificity of Eave were 86.7% and 85.0% for the diagnosis of high-risk BCC, respectively. Conclusion:High-frequency ultrasound and shear wave elastography can facilitate differential diagnosis between high- and low-risk BCC.

Objective:To explore superior mediastinal lymph node zoning of thyroid cancer for accurate anatomical definition as a reference for surgical access. Methods:A method for zoning superior mediastinal lymph nodes for thyroid cancer was proposed. From Sep 2018 to Nov 2019, 36 cases of thyroid cancer with superior mediastinal lymph nodes metastases were reviewed. The diagnosis, surgical approaches, pathology, characteristics of lymph node metastasis, complications and follow-up results were analyzed.Results:The superior mediastinal lymph nodes were grouped into 10 areas: 1, 2Ra, 2Rb, 2La, 2Lb, 3A, 3P, 4R, 4La and 4Lb. According to the location of the superior mediastinum metastatic lymph nodes, direct vision approach through the neck incision, laparoscope-assisted approach, thracoscepy, laparoscope-assisted combined with thrascopy approach or conventional median sternotomy was performed for regional lymph node dissection. The average follow-up time was (10±4) months. No residual or recurrence of tumor in superior mediastinal area was found.Conclusions:The zoning of the superior mediastinal lymph nodes in thyroid cancer can be used as a guide for surgical approach to lymph node dissection .

Objective:To explore the application value of bedside lung ultrasound score(LUS)in evaluating patients with primary graft dysfunction(PGD)after lung transplantation.Methods:A total of 35 PGD patients after lung transplantation in surgical intensive care unit from June 2018 to May 2020 were selected as research objects. After lung transplantation, one physician collected the clinical data, including age, gender, preoperative 24 h APACHE II score, postoperative hemodynamic parameters, lactate and respiratory parameters; another physician was responsible for LUS examination and LUS at 12/24/48/72 h post-operation. The correlation between LUS and oxygenation index was analyzed by bivariate correlation analysis. Receiver operating characteristic curve(ROC)was utilized for calculating the predictive value, sensitivity and specificity of LUS score for severe PGD.Results:A negative correlation existed between LUS and oxygenation index in single lung transplant( r=-0.536, P<0.01)and a negative correlation between LUS and oxygenation index ( r=-0.518, P<0.01)in double lung transplant. The area under ROC curve of LUS showed that the predictive value of LUS of severe PGD patients with single lung transplant was 7.0 with a sensitivity of 86.7% and a specificity of 72.1%, the predicted value of LUS of severe PGD in double lung transplant was 13.0 with a sensitivity of 83.3% and a specificity of 60.0%. Conclusions:Lung ultrasound is simple and easy to operate and LUS can evaluate the severity of PGD patients after lung transplantation. It has a high potency of guiding clinical diagnosis and treatment.

Objective:To study the influence of different feeding patterns on mother-to-child transmission (MTCT) of hepatitis B virus (HBV) in pregnant women with high viral loads who received antiviral medication during pregnancy to the day of delivery.Methods:This prospective cohort study was conducted in Beijing You'an Hospital. From January 1, 2019, to March 31, 2020, and 574 pregnant women with positive hepatitis B surface antigen (HBsAg) and HBV DNA>2×10 5 IU/ml were enrolled. All participants received tenofovir, telbivudine, lamivudine, or propofol tenofovir from 24-28 weeks of gestation and discontinued on the day of delivery, and their neonates were postnatally given routine passive-active immunoprophylaxis. Based on the feeding patterns, the subjects were divided into three groups: breastfeeding ( n=257), bottle-feeding ( n=241) and mixed feeding groups ( n=76). The follow-up data were obtained from liver functions and HBV DNA level of the mothers at 6-8 weeks postpartum and HBV serological markers of infants at 7-12 months. One-way ANOVA, Student-Newman-Keuls, Chi-square test or Fisher exact test, and repeated measures ANOVA were used to analyze the data. Results:The average maternal HBV DNA levels before antiviral treatment did not differ significantly between the three groups [(7.90±0.67), (7.82±0.70), (7.83±0.70) log 10 IU/ml, F=0.912, P>0.05]. HBV DNA level before delivery in the mixed feeding group was slightly lower than that in the breastfeeding and bottle-feeding group [(3.87 ±1.08) vs (4.21±1.17) and (4.30±1.28) log 10 IU/ml, q= 3.052 and 3.831, both P<0.05], while the comparison between the latter two groups showed no significant differences ( P>0.05). After delivery, HBV DNA level in the bottle-feeding group was slightly lower than that in the breastfeeding group [(7.42±0.93) vs (7.69±0.90) log 10 IU/ml, q=4.583, P<0.05]. Among 580 infants (including six pairs of twins), only one bottle-fed infant (0.4%, 1/243) was infected with HBV through MTCT, and none in the breastfeeding or mixed feeding group ( P=0.553). Conclusions:For pregnant women with high viral loads of HBV who have received antiviral medication during pregnancy, although HBV DNA level will rebound after discontinuation upon delivery, breastfeeding is recommended considering it does not increase the risk of MTCT.

Objective:To investigate the clinical characteristics of four McCune-Albright syndrome (MAS) patients associated with growth hormone(GH)-prolactin(PRL) pituitary adenoma, and explore more effective clinical treatment and management methods.Methods:The clinical data of four patients with MAS and GH-PRL pituitary adenoma diagnosed by Peking Union Medical College Hospital were retrospectively analyzed, including clinical manifestations, biochemical parameters, radiographic characteristics, as well as treatment and prognosis. Literature review was also conducted to analyze the efficacy of surgical operations and drug intervention.Results:Clinical characteristics: 3 females and 1 male, all of whom had onset before the age of 7 years. The types of fibrous dysplasia of bone were all polyosseous and involved craniofacial region. There were obvious gigantism/acromegaly manifestations in all cases, 3 cases had evident visual impairment and 1 case with optic chiasm compression. There was no spontaneous or triggered lactation in all 4 patients. Laboratory examination: GH and insulin-like growth factor-Ⅰ(IGF-Ⅰ) levels were significantly increased in 4 patients, GH levels were not inhibited by oral glucose tolerance test (OGTT), PRL levels were over 100 ng/ml, ALP levels were significantly increased in 4 patients, while serum calcium and phosphorus levels were remained normal. Imaging features: All pituitary adenomas in 4 patients were macroadenomas, with unilateral cavernous sinus enclosure in cases 2 and 3, and recurrence of macroadenoma with bilateral cavernous sinus enclosure in case 4 after the first operation. Four cases of skull CT showed multiple FD in craniofacial bone and skull base. Treatment and outcome: All 4 patients underwent pituitary adenoma resection and bisphosphonate therapy, and somatostatin analogues, dopamine receptor agonists and other treatments were selected according to the situation. Two patients with early diagnosis and initial treatment achieved partial remission after treatment, while the other two patients did not.Conclusions:Patients with MAS and GH-PRL pituitary adenoma had earlier onset age and were more likely to suffer from optic nerve damage. Early diagnosis and reasonable surgical treatment may help to improve biochemical indicators (GH, IGF-Ⅰ, and PRL, etc.) rapidly, and combined drug therapy (somatostatin analogues and dopamine receptor agonists) can better maintain or close to normal biochemical indicators, and ultimately improve the prognosis of patients.

Objective: To study the clinical characteristics of mucosal melanoma in the head and neck, including the risk factors affecting distant metastasis, recurrence and survival rate, and to provide the basis for the individualized treatment of mucosal melanoma in the head and neck. Methods: The clinical data of 117 cases of mucosal melanoma in the head and neck treated from January 2004 to June 2016 in Beijing Tongren Hospital were analyzed retrospectively, and the risk factors affecting the prognosis, distant metastasis and local recurrence were analyzed.Kaplan-Meier analysis was used for survival analysis, and Log-Rank test was used for comparison between groups. Results: The follow-up time was 5-139 months, with a median of 32 months, and the median survival time was 34 months.The 3 and 5 year cumulative survival rates were 47.0% and 25.0%, respectively.Local recurrence occurred in 27 patients (23.1%), and distant metastasis in 37 cases (31.6%). After the operation, 50 patients received radiotherapy.Multiple factor Cox regression analysis showed that distant metastasis, AJCC staging, and two operations were risk factors affecting survival (P<0.05), and immunologic/targeted therapy was a protective factor affecting survival prognosis(P=0.008). Postoperative radiotherapy and distant metastasis were important factors affecting recurrence (P<0.05). AJCC staging, pigmentation, and postoperative recurrence were risk factors for distant metastasis (P<0.05). Conclusion The 3 and 5 year survival rates of primary mucosal melanoma in head and neck are low, and the incidence of local recurrence and distant metastasis are high. Surgery is the first choice and the integrity of the initial operation has an important impact on the prognosis of the patients. Postoperative adjuvant radiotherapy is recommended to improve the local control rate, and immunotherapy and targeted therapy should be applied in time to improve survival.
