OBJECTIVE: To demonstrate the regularity of velopharyngeal function recovery after primary cleft palatoplasty and its correlation with different surgical procedures, ages, cleft types, and follow-up times. METHODS: Patients with cleft palate under 5 years old who had more than two follow-up records were included in this study, and consecutive evaluations of postoperative velopharyngeal function were performed. Univariate and multivariate logistic regression analysis were used to reveal the regularity of postoperative velopharyngeal function and the possible influencing factors. RESULTS: A total of 165 patients were included. Inconsistent functions of the velopharyngeal closure were observed in 31 patients, of which velopharyngeal insufficiency (VPI) in the first follow-up converted to velopharyngeal competence (VPC) in the second follow-up, accounting for 18.79% of the total, and 134 patients had consistent velopharyngeal function. The patients in the group who had consistent velopharyngeal function were younger than those in the group who were inconsistent, and the differences between the two groups were statistically significant. The younger the operation age, the patient's velopharyngeal function was more likely to stabilize at the first follow-up. At the time of the first follow-up in 15, 28, and 40 months, the probability that the patients had stable postoperative velopharyngeal function was 80%, 90%, and 95%, respectively. CONCLUSIONS The recovery of velopharyn-geal function after surgery is a dynamic process. The velopharyngeal status of patients can be converted from VPI to VPC. Meanwhile, VPC cannot switch to VPI. The follow-up time is the most important factor affecting the consistency of the evaluation of velopharyngeal function. Choosing appro-priate follow-up time is the key to obtain the stable evaluation of velopharyngeal function.

Objective: The present study aimed to investigate the association of red meat usual intake with metabolic syndrome (MetS), and explore the contribution of red meat usual intake to serum ferritin. Methods: Based on the data from the longitudinal China Health and Nutrition Survey (CHNS), 2,797 healthy adults aged 18-75 years without hypertension, diabetes, and MetS were selected in 2009 as subjects and follow-up studies were carried out till 2015. We used the National Cancer Institute (NCI) method to estimate the usual intake of foods. Multivariable logistic regressions were performed to evaluate the association between red meat usual intake and the risk of MetS. Quantile regression analysis was used to study the relationship between red meat consumption and serum ferritin levels. Results: After adjusting for potential confounders, red meat, and fresh red meat were positively associated with the risk of MetS ( = 1.41, 95% : 1.05-1.90 and = 1.37, 95% : 1.02-1.85, respectively). These relationships showed increasing trend ( < 0.05). The level of serum ferritin increased significantly with the number of MetS components ( < 0.05). The quantile regression analysis showed that red meat and fresh red meat usual intake had a significant positive association with serum ferritin levels across the entire conditional serum ferritin distribution ( < 0.05). Processed red meat did not exhibit a similar association. Conclusion Higher red meat usual intake was associated with an increased risk of MetS and elevated serum ferritin levels.

OBJECTIVE: To investigate the clinical efficacy, related side-effectt and long-term survival condition of Philadelphia chromosome positive acute lymphoblastic leukemia (Ph ALL) patients treated with second generation TKI dasatinib and chemotherapy followed by allogeneic hematopoietic stem cell transplantation (allo-HSCT). METHODS: Clinical data of 19 newly diagnosed as Ph ALL patients treated by dasatinib, chemotherapy and allo-HSCT from January 2012 to September 2018 were collectd and analyzed. RESULTS: There were 10 males and 9 females with median age of 29 years old. 14 patients were BCR/ABL P190 positive while 5 with BCR/ABL P210 positive. Three patients had complex karyotype, and 3 cases were confirmed to have central nervous system leukemia. All the patients received treatment with the induction chemotherapy regimen of VDCLP and consolidation regimens such as HD-MTX and MAE. 11 patients (57.9%) received dasatinib during induction chemotherapy, 3 patients (15.8%) received dasatinib after remission and 5 patients (26.3%) received dasatinib to replace imatinib. Side-effect appeared in 3 patients including rash, edema and nausea. All the patients got morphological remission and 7 patients(63.6%) got MMR after 4 weeks of induction chemotheraphy. 17 patients (89.5%) got MMR and 15 patients(78.9%) got CMR before allo-HSCT. All the patients received related bone marrow and peripheral hematopoietic stem cell transplantation from related donors, the median time of WBC and platelet engraftment were 12 d and 14 d after transplantation, respectively. The incidence rate of aGVHD and cGVHD were 42.1% and 57.9% respectivety. 13 patients received therapy of dasatinib after HSCT but 7 patients discontinued because of severe headache, vomiting and serious effusions. All the patients were followed-up for the median time of 42 months, the 3-year and 5-year OS both were 94.4%, and 3-year and 5-year RFS of 81.9% and 71.6%, respectively. CONCLUSION First-line administration of dasatinib and chemotherapy followed by allo-HSCT for treatment of PhALL is effective and patients can well-tolerate, the patients long-tern survival maybe superior to that of the patients treated with first generation TKI.

OBJECTIVE: To investigate the efficacy and safety of arsenic trioxide combined with ATRA and chemo- therapy for treatment of relapsed acute promyelocytic leukemia (APL) patients. METHODS: The clinic data of 25 patients with relapse APL treated in our hospital from 1996 to 2013 were collected and analyzed. Among the 25 patients, 15 patients suffered first-time hematological relapse (HR), and the other 10 patients showed first-time molecular relapse (MR). The patients with first-time replase were treated with ATO+ATRA+Anthracycline re-induction chemotherapy. The clinical features, complete remission (CR) rate, overall survival (OS), disease-free survival (DFS) and adverse events after re-induction therapy were analyzed. RESULTS: Fourteen of 15 hematological relapsed patients achieved the second-time hematological complete remission (CR2) after re-induction therapy except one patient died of bleeding complication during the re-induction. 8 of 14 patient showed molecular complete remission (CRm) after two cycles of therapy with this regimen. Totally, eleven out of the 14 HR patients were alive without disease till the last follow-up, and 3 of the 14 HR patients died because of bleeding complications. All of the 10 molecular relapsed patients received the second CRm after treated by the regimen. Among these 10 patients, 6 patients suffered only once relapse and continued with the molecular CR2 status, and for the other 4 patients with more than two-relapses, only 1 survived untill 89.3 months after achieved second-time CRm, and other 3 patients died because of bleeding complications. CONCLUSION For relapsed APL patients, the treatment with ATO+ATRA+chemotherapy regimen after relapse still shows encouraging efficacy, no matter whether or not the application of ATO in the previous regimens. In addition, patients with more than two molecular relapses show a poor prognosis.

The current document is based on a consensus reached by a panel of experts from the Chinese Society of Allergy and the Chinese Society of Otorhinolaryngology-Head and Neck Surgery, Rhinology Group. Chronic rhinosinusitis (CRS) affects approximately 8% of Chinese adults. The inflammatory and remodeling mechanisms of CRS in the Chinese population differ from those observed in the populations of European descent. Recently, precision medicine has been used to treat inflammation by targeting key biomarkers that are involved in the process. However, there are no CRS guidelines or a consensus available from China that can be shared with the international academia. The guidelines presented in this paper cover the epidemiology, economic burden, genetics and epigenetics, mechanisms, phenotypes and endotypes, diagnosis and differential diagnosis, management, and the current status of CRS in China. These guidelines—with a focus on China—will improve the abilities of clinical and medical staff during the treatment of CRS. Additionally, they will help international agencies in improving the verification of CRS endotypes, mapping of eosinophilic shifts, the identification of suitable biomarkers for endotyping, and predicting responses to therapies. In conclusion, these guidelines will help select therapies, such as pharmacotherapy, surgical approaches and innovative biotherapeutics, which are tailored to each of the individual CRS endotypes.

BACKGROUND: Post-infarct left ventricular free wall rupture (LVFWR) is not always an immediately catastrophic complication. The rupture can be subacute, allowing time for diagnosis and intervention. Accordingly, early recognition of the entity may be lifesaving. METHODS: We present an electrocardiogram (ECG) change pattern in two cases, which was erroneously attributed to ischemia. Two women in their 80s were admitted to our institute after experiencing the sudden onset of chest pain. They were managed as anterior ST-segment elevation myocardial infarction without reperfusion treatment. Unfortunately, they experienced a recurrence of severe chest pain with cardiogenic shock during hospitalisation. The ECG recorded at that time showed a ST-segment re-elevation in infract-related leads. RESULTS: The two cases were regrettably received a misjudgement of reinfarction at first, and one of the patients even was administrated with tirofi ban. Afterwards the diagnosis of subacute LVFWR was made through antemortem echocardiography. CONCLUSION: New ST-segment elevation (STE) in infarct-associated leads, coupled with recurrence of chest pain and new-onset hypotension, may constitute the premonitory signs of a subacute LVFWR.

Oral transmucosal drug delivery can be defined as the administration of drug through the oral mucosa to achieve systemic effects. It has the advantages of high bioavailability and rapid drug response. In this review, we introduce the physiology of oral mucosa, and analyze the factors affecting the pharmacokinetic properties of oral transmucosal drug delivery in detail, such as physiological barriers, different administration sites, physicochemical properties of drugs, dosage forms, and formulation strategies. In addition, we describe the methods to evaluate the pharmacokinetic properties of this delivery systems, including in vitro permeability studies, buccal absorption studies, in vivo pharmacokinetic studies and physiologically based pharmacokinetics (PBPK) modeling, which provide methods and reference for the development of oral transmucosal drug delivery systems.

Objective: To compare the irradiated dose to unprotected lymph node stations (LNS) between volume-modulated arc therapy (VMAT) and 5-field intensity-modulated radiotherapy (5F-IMRT) in the treatment of patients with upper thoracic esophageal cancer. Methods: A total of 20 patients were selected for re-planning. LNS were not included in the GTV and CTV, instead, LNS were contoured as normal tissues. However, LNS were not constrained in the VMAT and 5F-IMRT inverse optimization for protection. Dosimetric parameters of conformal index (CI), homogeneity index (HI) of targets, V₉₅, V₁₁₀ of planning target volume (PTV), D_mean, V₅, V₂₀, V₃₀ of lung, D_mean, V₂₅ of heart, D_max of spinal cord, MU, as well as the equivalent uniform dose (EUD) and V₄₀ of LNS were compared between the two plans. Results: 5F-IMRT was superior in PTV_V_95% (t=-9.4, P<0.05), but worse in terms of CI (t=-5.3, P<0.05) compared with VMAT. 5F-IMRT reduced the V₅ of lung by 10.9% (t=-7.8, P<0.05) and the D_max of spinal cord by 9% (t=-10.2, P<0.05), but increased the MU (t=-6.2, P<0.05) compared with VMAT. The average EUD and V₄₀ of LNS in upper thoracic were significantly increased by 4.7% and 2.4% in 5F-IMRT compared with VMAT, respectively. The irradiated doses to LNS were significantly associated with the volume of PTV (R=0.716-0.933, P<0.05) expect for 106tbL. Conclusions The irradiated doses to unprotected LNS were less for IMRT plans and were highly associated with PTV volume in patients with upper thoracic esophageal cancer.

Objective: To improve the awareness of emergency biliary obstruction (BO) disease, and to further improve the diagnosis and treatment ability of BO patients. Methods: Data of the etiology, clinical manifestations, imaging data, laboratory tests, and emergency treatment outcomes in 63 BO patients were retrospectively analyzed. Results: Common bile duct stones were the most common cause of BO patients (63.49%), followed by cholangiocarcinoma (19.05%); the most common clinical manifestations of BO patients were jaundice (90.48%), abdominal pain (87.30%), and fever (53.97%); the diagnostic ability of computed tomography (CT) and magnetic resonance cholangiopancreatography (MRCP) in patients with BO was significantly higher than that of ultrasound (P<0.05), but there was no significant difference between CT and MRCP (P=1.000); compared with benign group, hemoglobin and albumin in malignant group were significantly lower, while total bilirubin and direct bilirubin were higher, with statistically significant difference (P<0.05). Most patients in BO patients improved after treatment, and the mortality rate of BO patients was 3.17%(2/63) at the end of emergency visit. Conclusions Common bile duct stones and cholangiocarcinoma are still the most common causes of emergency BO patients. The most common clinical manifestations of patients with emergency BO are jaundice, abdominal pain, and fever. Better than abdominal ultrasound, CT and MRCP have comparable diagnostic capabilities in the diagnosis of emergency BO patients. Anemia, hyperbilirubinemia and hypoproteinemia are alarm indicators for malignant tumors in emergency BO patients. Most patients can temporarily get better at the end of emergency visit.

From July to August 2018, a survey on the awareness of diabetic foot screening was conducted using the online questionnaires posted on the WeChat group. From 107 trainees in General Practitioner Teacher Training Program of Beijing Xicheng District and 50 general practitioners working in Chinese Academy of Sciences, 145 valid questionnaires were received. All 145 participants worked in community health care settings, including 105 general practitioners, 76 had 10 to 20 years of service, and 98 had undergraduate degree. The survey showed that 75.9% (110/145) heard the diabetic foot screening and knew that screening should be done for all diabetic patients; 98.6% (142/145) knew that the screening should include medical history, foot skin, neuropathy, vascular status, and 73.1% (106/145) also knew that screening should include the foot bone, joint deformities and footwear selection; 21.4% (31/145) had participated in training related to diabetic foot screening. It is suggested that the awareness and knowledge of diabetic foot screening among Beijing community medical personnelare not sufficient, and more training opportunity is necessary for them.
