Objective To investigate the short-term efficacy of celiac plexus block combined with the interstitial permanent implantation of 125I seeds in the treatment of advanced pancreatic cancer(inoperable locally advanced and metastatic pancreatic cancers).Methods A total of 100 patients with advanced pancreatic cancer were selected and treated with celiac plexus block combined with the interstitial permanent implantation of 125I seeds under CT guidance.Pain relief and changes in the tumor marker CA19-9 were assessed on the seventh day,the first and third months after surgery.In the third month after surgery,tumor size was assessed by CT.Results Among the 100 patients with advanced pancreatic cancer,complete response(CR)was found in 12 cases,partial response(PR)in 78 cases,stable disease in five cases,and progression of disease in five cases three months after surgery.The CA19-9 level and the sum of short and long tumor diameters were significantly decreased(both P<0.01).A total of 100 patients had severe pain before treatment(visual analogue scale(VAS)):7-10 points),59 patients reported pain disappearance(VAS:0 points),35 patients had mild pain(VAS:1-3 points),and six patients experienced moderate pain(VAS:4-6 points)in the third month after treatment.The pain relief rate was 100%.Conclusion Celiac plexus block combined with the interstitial permanent implantation of 125I seeds has good short-term efficacy and can effectively improve short-term pain in patients with advanced pancreatic cancer.

Objective:To investigate the concern about pollen broadcasting in Chinese population from multiple dimensions and to understand the information about allergic rhinitis (AR) in China by analyzing related factors.Methods:From March 1 to September 30, 2022, a large-scale multi-center cross-sectional survey was conducted based on the Questionnaire Star platform in 21 Chinese hospitals. A total of 7 056 subjects from 7 regions in China: Northeast, North, East, Central, South, Southwest, and Northwest China were included. Basic characteristics (including social demographic characteristics and disease characteristics of AR patients), concern about pollen broadcasting, the willingness of pollen-induced AR (PiAR) patients to receive pollen broadcasting, and the treatment satisfaction rate of AR patients were collected. The chi-square test, multivariate linear regression model, and Logistic regression analysis were used to analyze the concern about pollen broadcasting in the Chinese population and related factors from multiple dimensions.Results:Among 7 056 subjects, 23.02% were concerned about pollen broadcasting. Among 3 176 self-reported AR and 1 019 PiAR patients, 25.60% and 39.16% were concerned about pollen broadcasting, respectively, which was higher than that of non-AR or non-PiAR subjects ( χ2 value was 21.74 and 175.11, respectively, both P<0.001). Among AR patients, the proportion of spring and autumn allergen-positive patients concerned about pollen broadcasting was higher than that in perennial allergen-positive patients ( χ2 value was 20.90 and 19.51, respectively, both P<0.001). The proportion of AR patients with asthma, sinusitis, allergic conjunctivitis, and cardiovascular and cerebrovascular diseases was higher than those without complications ( χ2 value was 50.83, 21.97, 56.78, 7.62, respectively, all P<0.05). The proportion of AR patients in North China who could find pollen broadcasting locally was 31.01%, significantly higher than those in other regions (all P<0.05). Multivariate linear regression model analysis showed that among PiAR patients, those with higher per capita household income and higher AR disease cognition levels had been concerned about pollen broadcasting in the past, and those complicated with allergic conjunctivitis had stronger intention to receive pollen broadcasting (B value was 0.24, 0.13, 0.66, 0.47, respectively, all P<0.05). The higher the disease cognition level of PiAR patients, the stronger their willingness to actively participate in treatment ( R2=0.72, P<0.001). Only 18.89% of AR patients felt satisfied with the treatment effect. Logistic regression analysis showed that in AR patients, the treatment satisfaction rate was significantly higher among those concerned about pollen broadcasting compared to those who were not ( OR=1.83, P<0.001). Conclusions:Currently, the dissemination of pollen broadcasting in China is hindered by various factors such as disease cognition level. The treatment satisfaction among AR patients remains unsatisfactory.

Objective:To explore clinical features, diagnosis, localization, and therapeutic strategy of migratory pharyngeal and cervical esophageal foreign bodies.Methods:A total 23 cases of pharyngeal and cervical esophageal migratory foreign bodies were admitted between January 2015 and December 2021. There were 14 females and 9 males with the age ranged from 35 to 82 (55.0±12.7)years. In all the cases, esophageal CT was taken to confirm the esophageal foreign body. Multiplanar reconstruction (MPR) was performed to locate the foreign body from the horizontal, coronal and sagittal dimensions as well as the corrected reconstructed MPR. According to the location of the foreign body, appropriate surgical method was selected.The symptoms, complications, types of foreign body, positioning, surgical methods, and relevant information were recorded.Data were analyzed using the descriptive method and SPSS 25.0 software.Results:The clinical symptoms of 23 migrating esophageal foreign bodies included pharyngodynia (20/23), foreign body sensation (6/23), hoarsenss (1/23), difficulty in turning neck(1/23), difficulty in opening mouth (1/23), fever (7/23), poor appetite (1/23), and abdominal pain (1/23). The foreign bodies included 19 fish bones, 2 wires, 1 embroidery needle and 1 chicken bone. There were 9 cases (39.1%) of foreign bodies located in extraluminal cervical esophagus, 2 cases (8.7%) of foreign bodies located in the muscular layer of the cervical esophagus and 12 cases (52.2%) of foreign bodies located in pharynx. Twenty-one cases of foreign bodies were removed by cervical lateral incision, in which 11 were removed by cervical lateral incision directly, 10 by the second lateral cervical incision after the foreign bodies were accurately located by MPR and/or corrected MPR, 1 foreign body was removed by incision of the pharyngeal mucosa under suspension laryngoscope, 1 foreign body was removed by tracheoscopy. Compared with patients with intraluminal foreign bodies ( n=308) treated in the same period, intake of fishbone [19 (19/23) vs. 133 (82.6% (43.2%, 133/308), OR=7.31] and first visit was more than 24 hours [20(87.0%, 20/23) vs. 77(25.0%, 77/308), OR=17.2] were the significant risk factors of migratory esophageal foreign bodies. Conclusions:MPR and the corrected MPR can accurately locate the migrating pharyngeal and cervical esophageal foreign bodies, by providing more intuitive imaging evidence for doctors, which provide imaging basis for formulation of surgical programs. Foreign bodies in pharyngeal and cervical esophagus need to be treated as soon as possible, otherwise they are easy to migrate, leading lead to serious complications.

OBJECTIVE：To study the effects of Plantago asiatica polysaccharide on the proliferation ，migration and invasion of breast cancer cells ，and to investigate its mechanism preliminarily. METHODS ：Using human breast cancer cell MDA-MB- 231 as subjects ，MTT method was adopted to detect the effects of different concentrations of P. asiatica polysaccharide（8，16，32，64 mg/L）on the cell proliferation ability ，and survival rate of the cells was calculated. Scratch test and Transwell invasion test were used to detect the effects of different concentrations of P. asiatica polysaccharide（8，16 mg/L）on cell migration ability and invasion ability. Western blot assay was used to detect the expression of epithelial-mesenchymal transition （EMT）-related proteins [matrix metalloproteinase- 2（MMP-2），MMP-9，E-cadherin，N-cadherin，vimentin]. RESULTS ：Results of MTT assay showed that survival rate of the cells in 32，64 mg/L P. asiatica polysaccharide groups were significantly lower than control group （P＜0.05 or P＜0.01），so that 8，16 mg/L，which did not affect the cell survival rate ，were used as the follow-up drug concentrations. Compared with control group ，relative mobility （12，24 h），relative invasion rate and relative expression of MMP- 2，MMP-9， N-cadherin and vimentin protein were decreased significantly in 8，16 mg/L P. asiatica polysaccharide groups （P＜0.05 or P＜ 0.01），while relative expression of E-cadherin protein was increased significantly （P＜0.05 or P＜0.01）. CONCLUSIONS ：P. asiatica polysaccharide can inhibit the proliferation of breast cancer cells MDA-MB- 231，and inhibit the migration and invasion of the cells by regulating the expression of metastasis and EMT-related proteins.

Parapharyngeal space tumors are rare. According to the size, location, relationship with the vascular nerves, benign and malignant tumors, different surgical approaches are used. This article reviews surgical techniques, indications, complications and current advantages and disadvantages of transoral robotic surgery (TORS) for resection of parapharyngeal space tumors. To provide reference for the application of TORS in parapharyngeal space tumor surgery.

The laryngopharyngeal reflux disease (LPRD) is a general term for a series of symptoms and signs caused by reflux of the stomach contents to the upper part of the esophageal sphincter. In recent years, the laryngopharyngeal reflux (LPR) is getting more and more attention as laryngeal precancerous lesions and risk factors of laryngeal cancer. Laryngeal precancerous lesions plays a important role in the development of laryngeal cancer process. This article will review the role and mechanisms of LPR in the laryngeal precancerous lesions, and the status of anti-reflux in the treatment of laryngeal precancerous lesions.

OBJECTIVE: To investigate the clinical features, therapeutic methods and therapeutic efficacy of imflammatory myofibroblastic tumor(IMT)of the nasal cavity and paranasal sinuses. METHOD: Clinical data of 14 cases diagnosed as IMT by pathology were retrospectively analyzed. There were 8 males and 6 females,age ranging from 18 to 77 years. 12 cases of them were treated by surgery while 2 cases received postoperative radiotherapy. RESULT: All cases were operated. All the patients were followed up for a period of 1 to 7 years after operation and two cases were proved low grade IMT pathologically. Eight cases survived with no recurrence until the last follow-up and 6 cases relapsed, of which 4 cases died and 2 were alive with tumor. CONCLUSION IMT of the nasal cavity and paranasal sinuses is very rare. The diagonosis of IMT is based on pathology and immunohistochemistry. Proper diagnosis is essential to avoid mutilating and disfiguring surgical procedures. Radical excision is still the first choice of treatment for IMT of the nasal cavity and paranasal sinuses. Chemotherapy and radiotherapy may not be helpful to prevent recurrence after operation. Due to high recurrence rate, long-term follow up is necessary after operation.

OBJECTIVETo investigate the metabolic changes on proton magnetic resonance spectroscopy (¹H-MRS) in patients with first left basal ganglia infarction and their relationship with depression.

METHODSTwenty-two patients with first left basal ganglia infarction and 10 matched healthy controls were recruited in the study. Patients and controls underwent (1)H MRS scan and the spectrum of N-acetyl aspartic acid (NAA), choline (Cho) and creatinine (Cr) was recorded at the first week (D7) and 1 month after onset (M1), respectively. National Institutes of Health Stroke Scale (NIHSS), Ability of daily life (ADL), Hamilton Depression Scale (HAMD) were evaluated at D7, M1 and M6 after onset. The patients were classified into two groups: post-stroke depression (PSD) and non-post-stroke depression (NPSD) according to the result of HAMD.The differences of (1)H-MRS between these two groups were compared and their relationship with NIHSS and ADL was analyzed.

RESULTSAmong 22 patients 10 were diagnosed as PSD and 12 were NPSD. Compared to controls, NAA/Cr was significantly lower and Cho/Cr was significantly higher (P <0.05)in left prefrontal white matter and left basal ganglia in patients with infarct. Patients with PSD showed a lower NAA/Cr and higher Cho/Cr than NPSD patients (P <0.05). At M1 after onset, NAA/Cr in the left prefrontal white matter was significantly correlated with NIHSS (r=-0.551, P =0.032), while Cho/Cr was correlated with ADL (r=0.682, P=0.005)in PSD patients.

CONCLUSIONMetabolic changes shown on (1)H-MRS in patients with basal ganglia infarction may predict the occurrence of PSD.
