ABSTRACT

Objective:To investigate the clinical value of early gastroscopy for patients with hypopharyngeal cancer.Methods:A total of 231 cases of hypopharyngeal cancer diagnosed and treated in the First Affiliated Hospital of Xiamen University from January 2010 to December 2014 were included in the retrospective analysis. The 5-year survival rate of hypopharyngeal cancer and patients accompanied with synchronous esophageal cancer (including early and advanced esophageal cancer), as well as the detection rate of synchronous esophageal cancer by gastroscopy and systemic PET-CT examination were statistically analyzed.Results:The 5-year survival rate of hypopharyngeal cancer was 38.96% (90/231). The 5-year survival rates of 62 patients accompanied with synchronous esophageal cancer and 169 patients without were 27.42% (17/62) and 43.20% (73/169), respectively, with statistic difference ( χ2=4.747, P=0.029). The 5-year survival rate of 49 patients accompanied with synchronous early esophageal cancer was 30.69% (17/49). Among the 13 patients with synchronous progressive esophageal cancer, none had a survival period of 5 years, which was significantly different compared with the patients with synchronous early esophageal cancer ( P=0.013). The detection rates of synchronous esophageal carcinoma by gastroscopy and by systemic PET-CT were 26.84% (62/231) and 14.29% (33/231), respectively, with statistic difference ( χ2=11.14, P<0.01). The detection rates of synchronous early esophageal carcinoma by gastroscopy and by systemic PET-CT were 21.21% (49/231) and 8.66% (20/231), respectively, and the difference was also statistically significant ( χ2=14.328, P<0.01). Conclusion:Hypopharyngeal cancer accompanied with synchronous esophageal cancer is of high risk, which affects the survival rate of patients. Early gastroscopy in hypopharyngeal cancer patients can significantly improve the detection rate of synchronous esophageal cancer, which helps to design individualized regimen to improve the survival rate of patients.

ABSTRACT

Objective:To analyse the MRI features of hilar schwannomas and pathology.Methods:The MRI and pathological features of 5 patients with hilar schwannomas which were confirmed histopathologically at Zhongshan Hospital, Fudan University from January 2012 to August 2019 were retrospectively analyzed. There were 3 males and 2 females, with age ranging from 47 to 67 years (median age 59 years). Contrast-enhanced MRI scans were performed in these 5 patients. The site, shape, size, edge, signal and enhancement pattern of these lesions and pathologicl findings were analysed.Results:All the lesions were single, located in and around the perihilar region. Four lesions were oval or roundish, and 1 lesion was sausage-shaped. Two lesions were solid while 3 lesions were cystic solid. All lesions had clear borders with intact capsules. The solid parts in all the lesions showed isointensity or slightly hypointensity on T 1 weighted imaging, hyperintensity on fat-suppression T 2 weighted imaging (T 2WI), hyperintensity on diffusion weighted imaging, slightly hyperintensity / isointensity / slightly hypointensity on apparent diffusion coefficient maping with progressive mild to moderate enhancement. Thick septum was observed in the cystic part. The septum and capsule showed mild to moderate delayed enhancement. Fluid-fluid level was seen in one lesion. The cystic solid lesion in one patient showed the " target sign" on fat-suppression T 2WI. All the 5 tumors were close to blood vessels, and their long axes followed the shape of the portal vein. In 1 patient, the lesion slightly compressed the adjacent bile ducts. Pathological examination showed that all the tumors in the 5 patients had complete fibrous envelopes, and the solid parts of the tumor showed mainly spindle cells. Conclusions:The MRI features of hilar schwannomas were oval or sausage-shaped lesions, with the long axis along the portal vein. They were prone to develop cystic changes, and a"target sign"could be shown on fat-suppression T 2WI. The solid parts, septa and capsules of the lesions showed mild to moderate progressive enhancement after contrast-injection.

ABSTRACT

Objective:To study the efficacy of dental floss traction-assisted endoscopic submucosal dissection (ESD) for gastric angle mucosal lesions.Methods:Data of 127 patients with gastric angle mucosal lesions admitted to the endoscopic center of the First Affiliated Hospital of Xiamen University from January 2015 to December 2018 were retrospectively analyzed. According to the surgical methods, patients were divided into the dental floss traction-assisted ESD group (the traction group, n=51) and the traditional ESD group (the traditional group, n=76). The 41 fibrosis cases were further divided into the traction group (n=23) and the traditional group (n=18). The operation time, en block resection rate, curative resection rate and the incidence of adverse events such as bleeding, muscle layer injury and perforation were compared between the two groups.Results:There was no significant difference in age, sex, lesion size or morphology between the traction group and the traditional group ( P > 0.05). The operation time of the traction group was significantly shorter than that of the traditional group (65.4±36.5 min VS 103.5±43.2 min, P=0.012). The en block resection rate was higher in the traction group [100.00% (51/51) VS 90.79% (69/76), P=0.026], and the curative resection rate was higher too [94.12% (48/51) VS 81.58% (62/76), P=0.042]. The incidences of muscular layer damage [5.88% (3/51) VS 25.00% (19/76), P=0.010] and intraoperative bleeding [47.06% (24/51)VS 82.89% (63/76), P=0.010] were lower in the traction group. Perforation occurred in two patients (2.63%) of fibrosis in the traditional group; no perforation occurred in the traction group. There was no significant difference in the perforation incidence ( P=0.243). In the cases of fibrosis, the operation time of the traction group was significantly shorter compared with that of the traditional group (81.4±29.3 min VS 119.3±37.6 min, P=0.010). The en block resection rate and curative resection rate were also higher in the traction group [100.00% (23/23) VS 72.22% (13/18), P=0.007; 95.65% (22/23) VS 72.22% (13/18), P=0.035]. The incidences of muscular layer damage [8.70% (2/23) VS 72.22% (13/18), P=0.001] and intraoperative bleeding [78.26% (18/23) VS 100.00% (18/18), P=0.035] were lower in the traction group. Conclusion:The dental floss traction-assisted ESD is safe and effective for gastric angle mucosal lesions and fibrotic lesions, with shorter operation time, higher curative resection rate and lower incidence of adverse events.

ABSTRACT

BACKGROUND:The effect of advanced glycation end products (AGEs) on bone resorption is controversial. Our previous study has shown that bone resorption is significantly inhibited when AGEs present with pre-osteoclast cells RAW 264.7, while the effect of AGEs on osteoclastic acidification remains unknown. OBJECTIVE:To investigate the effect of AGEs on osteoclastic acidification and the underlying mechanism. METHODS:RAW 264.7 cells were induced by RANKL (15μg/L;normal group) to generate osteoclasts, and AGEs (50-400 mg/L;experimental group) or bovine serum albumin (100 mg/L;control group) were added at the beginning of the induction. The effect of AGEs on bone resorption was evaIuated by anaIyzing the area of bone resorption on the Osteo Assay Surface plates, and the effect of AGEs on osteoclastic acidification was evaluated by acridine orange staining. Furthermore, the expression levels of V-ATPase a3 and CIC-7 were detected to investigate the underlying mechanism. RESULTS AND CONCLUSION:The bone resorption area in the AGEs group was significantly decreased compared with the normal group (P<0.05). Acridine orange staining reveaIed that the red fluorescence (620 nm) intensity in the AGEs group was significantly decreased compared with the normal group (P<0.05), and this inhibitory effect became obvious with the increase of AGEs concentration. Immunocytochemistry, western blot assay and PCR findings showed that the expression levels of V-ATPase a3 and CIC-7 in the AGEs group were decreased significantly compared with the normal group (P<0.05). To conclude, AGEs exert inhibitory effect on osteoclastic acidification, probably by inhibiting the expression of V-ATPase a3 and CIC-7.

ABSTRACT

BACKGROUND:The effects of advanced glycation end products (AGEs) on osteoclast-induced bone resorption is controversial and the underlying mechanisms remain unclear. Most of the studies indicate that AGEs can enhance bone resorption, while some othersshowthe opposite effects. OBJECTIVE:To investigate the effects of AGEs on osteoclast-induced inorganicmatrixdissolution and organic componentdegradation and the underlying mechanisms. METHODS:RAW 264.7 cels were induced to generate osteoclasts,and AGEs (50-400 μg/mL) or control-bovine serum albumin (100 μg/mL) was added since the beginning of the induction. The effect of AGEs on bone resorption was evaluated by analyzing the area of resorption pits on the Osteo Assay Surface plates and the expression of cathepsin K. Furthermore, the number of tartrate-resistant acid phosphatase (TRAP)-positive multinucleated cels, nuclei per osteoclasts and the expression of integrinανβ3were detected. RESULTS AND CONCLUSION:The area of resorption pits and expression of cathepsin K in AGEs groups were significantly decreased compared withthecontrol group, and this inhibiting effect became more obvious with the increase of AGEs concentration. TRAP staining also showed that number of TRAP-positivemultinucleated celsand nuclei per osteoclast were significantly reduced in an AGE dose-dependent manner. Quantitative PCR revealed that the expression of integrin ανβ3decreased significantly with the extension of AGEs incubation time. These data indicate that AGEs can exert inhibitory effects on organic and inorganicmatrixdegradation induced by osteoclasts. The underlying mechanism may be involved in the inhibitory effects of AGEs on directed differentiation and cel fusion of osteoclast precursor cels, and migration and adhension of osteoclasts.

ABSTRACT

TCM medical service trade is an important component of TCM service trade. Developing TCM medical service trade has wide market and strategic importance. Development of TCM medical service trade in China is still in the initial exploring stage with small scale and dominated by the government. Recently, foreign patients prefer TCM medical serve. TCM medical service trade in abroad shows the partial and small scaled characteristics. The number of joint venture TCM treatment centers is small, and movement of personnel is rare. In order to promote the development of TCM service trade, this article proposed the following four suggestions: conducting TCM international tele-medicine service trade, developing TCM medical travel, investing more in the development of foreign TCM medical centers, expanding the scale of exporting TCM medical talents.

ABSTRACT

BACKGROUND:The preemptive analgesia is stil a controversial issue. Existing studies have not paid much attention to effects of preoperative factors on the hypersensitivity of peripheral and central mechanisms. Visual analog scale scores cannot subjectively and repeatedly reveal patient’s pain. OBJECTIVE:To investigate the validity of the preventive analgesia effect of Celebrex in patients with total knee arthroplasty. METHODS:Patients with osteoarthritis of the knee who received total knee arthroplasty were accessed by Pittsburgh sleep quality index, self-rating depression scale and self-rating anxiety scale. In al , thirty patients were enrol ed in the study. They were randomized into Celebrex group and vitamin C group, and each group had 15 patients. The patients in the Celebrex group and vitamin C group took 200 mg Celebrex and vitamin C, respectively, twice a day from day 2 to day 4. Both of their knees were evaluated by resting visual analogue scale and moving visual analogue scale in the evening of day 1 before treatment and day 3 after treatment. Meanwhile, the pain threshold and pain tolerance were accessed by a pain-threshold machine. RESULTS AND CONCLUSION:No statistical significance of the changes of resting and moving visual analogue scale scores was found in both knees in the Celebrex group (P>0.05). The pain threshold of both knees were significantly increased (P0.05). There were no significant changes in the pain tolerance in both knees (P>0.05). The changing values of resting or moving visual analogue scale were not significantly correlated with the pain threshold and pain tolerance (P>0.05). There were no significant changes in visual analogue scale scores, pain threshold and pain tolerance in both knees of the vitamin C group (P>0.05). Celebrex could increase the pain threshold of patients receiving total knee arthroplasty, especial y the severe knee, which indicates that the Celebrex is good for the preventive analgesia. Comparatively speaking, the pain threshold might be more sensitive than visual analogue scale in revealing the change of pain after analgesia. There is no significant correlation between visual analogue scale score and the hypersensitivity of pain.
