Smoothened (SMO) is a member of sonic hedgehog homology (SHH) signaling pathway. It plays a key role as a bridge between patched-1 (PTCH-1) and Gli. Aberrant SHH expression can be detected in various malignant tissues, and the expression in pancreatic cancer stem cells is higher apparently. SHH signals are closely associated with self-duplication of cancer stem cells, formation of tumor vessels as well as matrixes. SMO antagonists such as cyclopamine, GDC-0449 and so on show potential to inhibit activity of SHH signaling, and arrest the growth as well as metastases of tumors. Recently, a few of SMO antagonists have been studied in phase I clinical trials and some are in phase II, meanwhile, phase I or II trials of SMO antagonists to treat pancreatic cancer are performed currently. As the classical SMO antagonist, cyclopamine is extracted from a medicinal plant. Perhaps researchers may be able to determine more effective SMO-targeting drugs from herbal medicines in the future.

Objective: To investigate the quality of life among patients with occupational pneumoconiosis in Jinhua City, Zhejiang Province, so as to provide insights into improving the quality of life among patients with occupational pneumoconiosis. Methods: Patients with occupational pneumoconiosis in Jinhua City from 2009 to 2021 were retrieved from the National Occupational Disease and Health Risk Factors Monitoring Information System. Participants' demographics, diagnosis of pneumoconiosis, stage of pneumoconiosis, pulmonary function and medical expense were collected through questionnaire surveys, and the quality of life was measured using a Chinese version of the Short-Form Health Survey (SF-36). The quality of life was descriptively analyzed among patients with occupational pneumoconiosis by disease stage, pulmonary function, expense for disease diagnosis and treatment and educational level. Results: A total of 244 patients with occupational pneumoconiosis were enrolled, including 225 men (92.21%). The participants had a mean age of (75.20±9.42) years, and mean duration from dust contact to pneumoconiosis onset of (13.11±9.89) years. The scores for physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health were (64.03±31.22), (45.14±44.22), (56.34±26.60), (40.80±19.80), (59.14±17.35), (68.41±19.67), (47.03±44.08) and (61.15±17.06) points among patients with occupational pneumoconiosis, which were all lower than the national constant (P<0.05). Lower scores were measured for physical functioning [(31.17±23.40) points], bodily pain [(45.21±19.50) points] and vitality [(47.00±20.70) points] among patients with stage Ⅲ occupational pneumoconiosis, for physical functioning [(32.27±24.24) points], role-physical [(12.88±30.70) points], bodily pain [(37.44±20.43) points], general health [(14.76±17.17) points], vitality [(38.79±19.33) points], social functioning [(53.33±17.08) points], role-emotional [(9.09±26.71) points], and mental health [(53.21±17.25) points] among occupational pneumoconiosis patients with severe pulmonary function damages, and for physical functioning [(30.97±27.40) points], bodily pain [(37.77±24.34) points], general health [(19.10±18.62) points], vitality [(38.39±23.78) points], social functioning [(55.89±21.00) points] and mental health [(55.35±20.35) points] among occupational pneumoconiosis patients that had personal payments for pneumoconiosis diagnosis and treatment expenses exceeding 30% of annual household incomes, while higher scores were measured for physical functioning [(66.36±17.33) points] and role-physical [(59.09±45.10) points] among occupational pneumoconiosis patients with an educational level of high school and above (all P<0.05). Conclusions The quality of life was low among occupational pneumoconiosis patients in Jinhua City from 2009 to 2021. Stage of pneumoconiosis, pulmonary function, medical expenses and educational level were identified as factors affecting the quality of life among occupational pneumoconiosis patients in Jinhua City.

Objective: To investigate the disease burden of occupational pneumoconiosis from 2009 to 2021 in Jinhua City, Zhejiang Province, so as to provide insights into formulating occupational pneumoconiosis prevention and control measures. Methods: Data on occupational pneumoconiosis in Jinhua City from 2009 to 2021 were collected through Occupational Disease and Health Hazard Monitoring Information System including demographic characteristics, disability level, age, pneumoconiosis type and stage, and analyzed years live dwith disability (YLD), years of life lost (YLL) and disability adjusted life years (DALY) by different genders, pneumoconiosis stages, pneumoconiosis types, ages and disability levels. Results: A total of 244 occupational pneumoconiosis cases were diagnosed in Jinhua City from 2009 to 2021, of which 225 cases were male, accounting for 92.21%. The median age of onset was 44.50 (interquartile range, 23.00) years. There were 229 deaths, with a median age of 78.00 (interquartile range, 13.00) years. The DALY was 3 791.88 person-years, YLD was 2 428.21 person-years (64.04%) and YLL was 1 363.67 person-years (35.96%). The YLD was 3 647.8 person-years in men, which was higher than 144.08 person-years in women (P<0.05). The YLD of asbestosis cases was lower than that of silicosis, coal workers' pneumoconiosis and other pneumoconiosis (P<0.05). The YLL was not statistically significant in the stage and type of occupational pneumoconiosis (P>0.05). The YLD was higher among cases at ages of less than 40 years, and lower among cases at ages of 60 to 69 years and 70 years and over (P<0.05); the YLL was lower among cases at ages of 70 years and over (P<0.05). The cases with second/third level of disability had the highest YLD, followed by the cases with fourth/fifth level of disability, and the cases with sixth/seventh level of disability had the lowest YLD (P<0.05). Conclusions The disease burden of occupational pneumoconiosis in Jinhua City from 2009 to 2021 is mainly induced by disability, and the disease burden caused by silicosis is the highest. With the progress of pneumoconiosis stages and disability levels, the life loss continues to increase.

Objective: To understand the health risk of drinking water in rural areas of Jinhua and to provide evidence for water sanitary management in rural areas. Methods: Totally 2 032 samples of drinking water in rural areas of Jinhua were collected from 2016 to 2018. According to GB/T 5750-2006 Standard Examination Methods for Drinking Water,five chemical carcinogens（As,Cd,Cr6+,CHCl3 and CCl4）and twelve non-carcinogenic chemicals（Pb,Hg,Se、CN-、F-、NO3-、Al、Fe、Mn、Cu、Zn and NH3-N）were detected. The health risk assessment in rural drinking water was conducted by United States Environmental Protection Agency（USEPA）model. Results: The total health risk,total carcinogenic risk and total non-carcinogenic risk of rural drinking water caused by the seventeen chemicals were 34.8×10-6/a,34.80×10-6/a and 6.65×10-9/a,respectively. The carcinogenic risk of five chemical carcinogens accounted for 99.98% of the total health risk,and the carcinogenic risk of Cr6+ accounted for 89.95% of the total health risk. The total health risk of the fully processed,partially processed and unprocessed water samples were 31.68×10-6/a,34.78×10-6/a and 34.77×10-6/a,respectively. The total health risk of finished water and peripheral water were 34.79×10-6/a and 34.82×10-6/a. Conclusion The health risk of drinking water in rural areas of Jinhuacaused by chemicals is low. The hexavalent chromium has the highest health risk and need more attention to be paid on.

We analyzed the whole genome coding sequence of Volvariella volvacea to study the pattern utilization of codons by Codon W 1.4.2. As results, 24 optimal codons were identified. Moreover, the frequency of codons usage was calculated by CUSP program. We compared the frequency of codons usage of V. volvacea with other organisms including 6 modal value species (Homo sapiens, Saccharomys cerevisiae, Arabidopsis thalian, Mus musculus, Danio rerio and Drosophila melanogaster) and 4 edible fungi (Coprinopsis cinerea, Agaricus bisporus, Lentinula edodes and Pleurotus ostreatus). We found that there were less differences in 3 edible fungi (excluding Pleurotus ostreatus) than 6 modal value species, comparing with the frequency of codons usage of V. volvacea. With software SPSS16.0, cluster analysis which showed differences in the size of codon bias, reflects the evolutionary relationships between species, which can be used as a reference of evolutionary relationships of species. This was the first time for analysis the codon preference among the whole coding sequences of edible fungi, serving as theoretical basis to apply genetic engineering of V. volvacea.

Objective To evaluate the clinical results of the Ilizarov technique for the treatment of the complex rigid talipes equinovarus deformities.Methods From July 2005 to July 2011,28 patients (41 feet) with rigid talipes equinovarus deformities which had been corrected with the Ilizarov technique were retrospectively analyzed,including 18 males (26 feet) and 10 females (15 feet) with an average age of 15.3 years.According to the classification system proposed by Diméglio,31 feet were categorized as grade Ⅲ,and 10 as grade Ⅳ.We performed corrections with a soft tissue release in 23 feet,and with a limited osteotomy in 18,and then a Ilizarov external fixator was applied.Anteroposterior and lateral X-rays were taken to compare the pre and postoperative data in terms of the angle of plantarflexion and dorsiflexion,the range of motion of the ankle joint,radiological measurements of the talocalcaneal angle.Results All the 28 patients achieved an outpatient follow-up,with an average of 25 months.All patients achieved a plantigrade foot with an almost normal appearance as the fixator was removed after applied for an average of 5.1 months (range,2-14).At the preoperative and final follow-up respectively,the angle of dorsiflexion of the foot was -45.0°±12.0° and 9.5°±5.5°,the angle of plantarflexion was 67.0°±14.0° and 45.5°±7.8°,talocalcaneal angle was 6.5°±4.5° and 22.5°±5.5° in anteroposterior radiograph and 5.5°±11.0° and 40.6°±8.5° in lateral radiograph.Spastic ischemia occurred in one foot and relieved by a slower distraction rate.Wire-hole infections occurred in 5 feet and treated by dressing changs,wire tract altering and antibiotic therapy,finally the infections were controlled.Deformity relapsed in one foot three months after the device was removed,then corrected with an additional fixator application and has not recurred till the final follow-up.Toe contracture and residual deformity occurred in 5 feet and 3 feet,respectively.Conclusion The Ilizarov technique is an effective method for correction of complex rigid talipes equinovarus deformities,with which the appearance and function of the foot could be kept as much as possible,and without impact on food development.

Hepatocellular carcinoma (HCC) accounts for approximately 75%-85% of primary liver cancer cases and is one of the most frequently diagnosed malignancies worldwide. Immunotherapy is currently considered to be the most promising treatment to prevent the progression and postoperative recurrence of HCC. At present, the treatment strategies of immunotherapy for HCC are classified as active immunotherapy and passive immunotherapy, including tumor vaccine therapy, immune checkpoint inhibitors, and adoptive cell therapy. Here we review the current clinical progression and discuss the future perspective on immune therapy for HCC.

Objective:To explore the safety and efficacy of pancreatic extracorporeal shock wave lithotripsy (P-ESWL) in treating painful chronic pancreatitis patients with pancreatic stones.Methods:The painful chronic pancreatitis patients receiving P-ESWL alone or P-ESWL combined with ERCP at Shanghai Pudong New Area Gongli Hospital from August 2019 to December 2021 were retrospectively analyzed. The success rate of stone fragmentation following P-ESWL, occurrence of postoperative complications, stone clearance rate of the main pancreatic duct and degree of pain relief in the follow-up were evaluated.Results:Among 113 patients, 7 patients were treated with P-ESWL alone and 106 patients were treated by P-ESWL combined with ERCP. The success rate of stone fragmentation was 98.2%. The occurrence of P-ESWL complications was 6.2%. Complete clearance of the main pancreatic duct stones was achieved in 75.2% of patients. With the mean follow-up of 17.5(3-31) months, complete pain relief was achieved in 84.1% of patients. The pain frequency and VAS score of patients treated with P-ESWL alone and P-ESWL combined with ERCP were obviously lower than those before treatment, and the body weight and body mass index were significantly higher than those before treatment, all with statistically significant differences (all P value <0.01). Conclusions:P-ESWL is safe and effective for the management of painful chronic pancreatitis patients with main pancreatic duct stones.

Purpose: This study aimed to develop a nomogram for predicting pathologic complete response (pCR) after neoadjuvant chemoradiotherapy (CRT) in patients with esophageal squamous cell carcinoma (ESCC) by integrating hematological biomarkers and clinicopathological characteristics. Materials and Methods: Between 2003 and 2017, 306 ESCC patients who underwent neoadjuvant CRT followed by esophagectomy were analyzed. Besides clinicopathological factors, hematological parameters before, during, and after CRT were collected. Univariate and multivariate logistic regression analyses were performed to identify predictive factors for pCR. A nomogram model was built and internally validated. Results: Absolute lymphocyte count (ALC), lymphocyte to monocyte ratio, albumin, hemoglobin, white blood cell, neutrophil, and platelet count generally declined, whereas neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) increased significantly following neoadjuvant CRT. After surgery, 124 patients (40.5%) achieved a pCR. The pCR group demonstrated significantly more favorable survival than the non-pCR group. On multivariate analysis, significant factors associated with pCR included sex, chemotherapy regimen, post-CRT endoscopic finding, pre-CRT NLR, ALC nadir during CRT, and post-CRT PLR, which were incorporated into the prediction model. The nomogram indicated good accuracy in predicting pCR, with a C-index of 0.75 (95% confidence interval, 0.71 to 0.78). Conclusion Female, chemotherapy regimen of cisplatin/vinorelbine, negative post-CRT endoscopic finding, pre-CRT NLR (≤ 2.1), ALC nadir during CRT (> 0.35 ×109/L), and post-CRT PLR (≤ 83.0) were significantly associated with pCR in ESCC patients treated with neoadjuvant CRT. A nomogram incorporating hematological biomarkers to predict pCR was developed and internally validated, showing good predictive performance.
