Objective To investigate the combination effect of curcumin and γ-ray irradiation on PANC-1 cells in vitro.Methods PANC-1 cells were exposed to γ-rays in the presence or absence of curcumin.MTT assay was performed to evaluate cell viability.The expression of P21 was evaluated with RT-PCR and Western blot.Cell cycle distribution and apoptosis were tested by flow cytometry.Results Compared with the γ-ray irradiation group,combination treatment of curcumin and irradiation decreased the cell viability (t =6.72,P ＜ 0.01) and increased the percentage of cells in S-phase (t =4.78,P ＜ 0.05),apoptosis rate (t =6.58,P ＜ 0.01),P21 protein and mRNA expression (t =5.72,5.63,P ＜ 0.01) in PANC-1 cells.Conclusions Curcumin increases the radiosensitivity of PANC-1 cells,which may have clinical implication on radiotherapy of pancreatic cancer.

Objective To investigate the effects of acupuncture on gene expression profile of neurotrophin and its receptors in cerebral cortex of neonatal rats after cerebral hypoxic-isehemic injury,and to explore the molecu- lar mechanism of acupuncture in treatment of neonatal hypoxic-ischemic encephalopathy.Methods The model of cerebral hypoxic-ischemic injury was established with 10 neonatal Sprague-Dawley(SD)rats,who were subjected to acupuncture once daily for 14 days.The animals were sacrificed on the next day of the last acupuncture and their brain cortex was sampled for examination of gene expression,using GEArray Q series neurotrophin and receptors gene array.Results After 14 days of acupuncture,it was found that 48 genes(50% of total genes on the microarray) were expressed differently between the two groups,of which 40 genes(83.3% of differently expressed genes),such as those of the brain-derived neurotrophic factor(BDNF),ciliary neurotrophic factor(CNTF),ciliary neurotrophic factor receptor(CNTFR),basic fibroblast growth factor(bFGF)and fibroblast growth factor receptor type 1 (FGFR1)were up-regulated,and 8 genes(16.7% of differently expressed genes),such as genes of neuregulin-1 (Nrg1),neuregulin-4(Nrg4)and tyrosine kinase C(TrkC)were down-regulated.Conclusion Acupuncture can regulate the expression of various genes of neurotrophin and receptors in cerebral cortex of neonatal rats after cerebral hypoxic-ischemic injury,which might be the mechanism of acupuncture facilitating the recovery of the rats from hy- poxic-ischemic encephalopathy.

Objective To determine the toxicity, maximal dose and clinical practicality of VM26 (teniposide) plus radiotherapy for postoperative brain neurospongioma. Methods Twenty patients were alloted in phase Ⅰ trial. The total dose was 60 Gy for the field radiotherapy (30 fractions of 2 Gy over six weeks). Teniposide at three dose levels (50 mg/m2, 75 mg/m2 and 100 mg/m2) was given intravenously once a week, totally five weeks. Dose escalation was based on each level, with a minimum of five patients in cohort if severe toxicity was not observed until the maximum tolerance dose(MTD). Results The predominant form of toxicity was hematologic toxicity. Four patients developed grade 3, 4 leucopenia when a second level of MTD (75 mg/m2) was given. Conclusion Combined radiotherapy and teniposide for postoperative brain neurospongioma is well tolerated. The dose of 50 mg/m2 for phase Ⅱ clinical trial was recommended.

Objective To observe the effect of recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) on the prevention and treatment of oral mucositis induced by concurrent chemoradiotherapy in patients with locally advanced nasopharyngeal carcinoma. Methods A total of 64 patients with locally advanced nasopharyngeal carcinoma from April 2015 to April 2017 in the Second Affiliated Hospital of Xi'an Jiaotong University were enrolled. The patients were randomly divided into the observation group (32 cases) and the control group (32 cases) according to the random number table method. Both groups were treated with intensity modulated radiotherapy (IMRT) and synchronized with TP regimen (docetaxel + cisplatin) chemotherapy for 2 cycles. Both groups were treated with mouthwash at the beginning of radiotherapy to prevent oral mucositis. The observation group was given rhGM-CSF mouthwash, and the control group was given compound borax mouthwash. The oral mucositis and the oral pain during the treatment and the end of the treatment were evaluated by using American Radiation Oncology Group (RTOG) grading criteria and visual analogue scoring method(VAS) grading criteria. The time of onset of oral mucositis and the total time of radiotherapy in both groups was also recorded. Results All the patients were treated with concurrent chemoradiotherapy. The total radiotherapy time in the observation group was less than that in the control group [(46.4±1.6) vs. (48.2±3.2) d, t= -2.720, P= 0.009]. The clinical total effective rate was 93.8 %(30/32) in the observation group and 96.9 %(31/32) in the control group respectively (χ2= 0.35, P =0.554).The occurrence of grade 1,2 and 3 oral mucositis in the observation group was(20.9±2.5), (29.3±2.4), and (34.5±1.8) d respectively, which was latter than that in the control group [(16.3 ±2.0), (24.2 ±2.2) and (31.0 ±2.2) d] respectively (t= 8.125, P= 0.000; t= 8.840, P= 0.000; t= 6.944, P= 0.001). During concurrent chemoradiotherapy,the incidence of grade 3 oral mucositis in the observation group was lower than that in the control group[31.2 %(10/32)vs.56.2 %(18/32);Z=-2.197,P=0.028].At the end of concurrent chemoradiotherapy, the total incidence of grade 2 and grade 3 oral mucositis in the observation group was lower than that in the control group [53.1 % (17/32) vs. 81.2 % (26/32); Z= -2.708, P= 0.007]. The incidence of moderate and severe oral pain caused by oral mucositis in the observation group was lower than that in the control group[46.9 %(15/32)and 6.2 %(2/32)vs.59.4 %(19/32)and 15.6 %(5/32),respectively;Z= -2.009, P= 0.045]. Conclusion rhGM-CSF mouthwash can delay the occurrence of oral mucositis, reduce the incidence of oral mucositis and oral pain to effectively prevent and treat oral mucositis induced by concurrent chemoradiotherapy in patients with locally advanced nasopharyngeal carcinoma, which is worthy of clinical application.

Objective To improve the recognition of synovitis-acne-pustulosis-hyperostosis-osteitis (SAPHO) syndrome by investigating its clinical features and imaging manifestations. Methods The data of 14 patients with SAPHO syndrome (8 males, 6 females, age range: 18-61 years) between January 2014 and January 2017 were retrospectively analyzed. The clinical features, the results of laboratory (erythrocyte sedimentation rate (ESR), C reaction protein (CRP), complement component 3 (C3) and component 4 (C4), human leukocyte antigen (HLA)-B27) tests, pathology and imaging examinations (CT and whole-body bone im-aging) were collected. Results SAPHO syndrome was mainly characterized by skin damage and bone joint damage. The main manifestations of skin lesions were pustules, desquamation and erythema. Those of bone and joint injury were sternocostoclavicular hyperostosis, stiff spinal hyperostosis, peripheral arthritis, and sacroiliitis. There were 5 with fasting ESR, 5 with abnormal CRP, 3 with abnormal C3, and 1 with abnormal C4 among 14 patients. HLA-B27 was negative in all patients. Whole-body bone imaging revealed that 14 pa-tients had abnormal radioactivity, mainly involving the anterior chest wall, spine, pelvis and long bone. Chest CT manifestations of the patients were the destruction of joint bone, the fusion of the hypertrophy and the narrowing of the joint space. Symmetric lesions accounted for the majority. Pathology examination showed non-specific inflammation in 9 patients. Conclusions SAPHO syndrome is a disease characterized by skin, bone and joint abnormalities. Whole-body bone imaging can find systemic bone damage in early stage, and CT can detect bone changes and soft tissue lesions.

Objective:To investigate the clinical application value of enhanced recovery after surgery using the LEER model in patients subjected to laparoscopic cholecystectomy in basic hospitals of Yi nationality area.Methods:Twenty-six patients who underwent laparoscopic cholecystectomy based on the concept of enhancing recovery after surgery using the LEER model in People's Hospital of Jinkouhe District of Leshan from January to October 2021 were included in the observation group. An additional 20 patients who concurrently underwent laparoscopic cholecystectomy and conventional intervention were included in the control group. Clinical efficacy, postoperative complications and postoperative pain were compared between the two groups.Results:Postoperative fasting time, length of hospital stay, and total hospital days in the observation group were 6 (6, 6) hours, 2 (2, 3) days and 4 (4, 6) days respectively, which were significantly shorter than 24 (24, 36) hours, 5 (5, 6) days, 7 (7, 9) days in the control group ( H = 351.00, 407.50, 458.00, all P < 0.05). Hospitalization cost in the observation group was 5 454.58 (5 014.11, 6 016.58) yuan, which was significantly lower than 6 611.91 (6 192.68, 7 841.73) yuan in the control group ( H = 420.00, P < 0.05). There were no significant differences in operative time and postoperative complications between the two groups (both P > 0.05). At postoperative 6 hours, Visual Analogue Scale score in the observation group was 3 (3, 4) points, and patients with mild pain accounted for 73.07% (19/26). At postoperative 24 hours, Visual Analogue Scale score in the observation group was 2 (2, 3) points, and patients with mild pain accounted for 92.31% (24/26). Overall pain was well controlled after surgery. Patient satisfaction rate in the observation was 96.15% (25/26). All patients recovered and were discharged. Conclusion:Application of enhanced recovery after surgery using the LEER model in patients subjected to laparoscopic cholecystectomy in basic hospitals of Yi nationality area can promote postoperative recovery, contribute to changing the theory of diagnosis and treatment, and improve overall medical quality. The enhanced recovery after surgery protocol using the LEER model has a good application value.
