ABSTRACT
Objective:To observe the effect of preoperative application of butorphanol tartrate on postoperative recovery quality in patients undergoing thoracoscopic lobectomy.Methods:A prospective selection was conducted on 96 lung cancer patients who underwent thoracoscopic lobectomy and were admitted to Linyi People′s Hospital from May 2021 to September 2021. They were randomly divided into observation group and control group using a random table number method, with 48 patients in each group. The observation group received intravenous injection of 0.02 mg/kg butorphanol tartrate 15 minutes before anesthesia induction; The control group was given an equal volume of physiological saline. The operation site, operation time, remifentanil dosage during operation, heart rate (HR) and mean arterial pressure (MAP) at each time point of admission (T 0), intubation (T 1), 5 min after intubation (T 2), extubation (T 3), 5 min after extubation (T 4), and 15 min into post-anaesthesia care unit (PACU) (T 5) were recorded; The awakening Restlessness score (RS), Ramsay score, Visual Analogue Scale (VAS) score at T 4 and T 5, the time required from completion to extubation, and postoperative anesthesia related adverse reactions were evaluated. Results:There was no significant difference in the operation site, operation time and remifentanil dosage between the two groups (all P>0.05). Compared with T 0, the HR at T 2, T 3 and T 4, MAP at T 1, T 2, T 3 and T 4 in the two groups decreased significantly (all P<0.05). The HR of the observation group at T 1 and T 3 was significantly lower than that of the control group, and the difference was statistically significant (all P<0.05). The VAS scores of T 4 and T 5 in the observation group were lower than those in the control group after surgery, while the Ramsay score were higher than those in the control group (all P<0.001). The incidence of postoperative restlessness, nausea and vomiting in the observation group was lower than that in the control group ( P<0.05). Conclusions:Administering 0.02 mg/kg butorphanol tartrate 15 minutes before anesthesia induction can improve the quality of recovery in patients undergoing thoracoscopic lobectomy, reduce restlessness and related adverse reactions during recovery.
ABSTRACT
Retinal degenerative diseases are a major contributor to visual impairment worldwide, and research related to retinal degenerative diseases is increasingly becoming a hot topic.The sigma-1 receptor is a 223-amino-acid endoplasmic reticulum transmembrane protein, and its gene sequence is highly conserved throughout mammals.Sigma-1 receptors are widely distributed in various tissues and organs.Numerous studies have proved the protective role of sigma-1 receptors in retinal pathological processes, including anti-oxidative stress, anti-inflammatory response, and anti-apoptosis.In addition, sigma-1 receptors have potential therapeutic roles in retinal diseases, especially diabetic retinopathy, retinitis pigmentosa and glaucomatous neuropathy.In this paper, the molecular mechanisms of sigma-1 receptor-mediated retinal neuroprotection and its application in the treatment of retinal diseases were reviewed.
ABSTRACT
The clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR-associated endonuclease 9 (Cas9) technology is a gene editing technology that uses RNA to guide endonucleases.This technology is rapidly used in gene editing and disease gene therapy in multiple species because of its easy operation, precise targeting, short cycle, and high gene knockout efficiency.At present, the corneal dystrophy model ( UBIAD1, TGF- β R124C gene mutations), glaucoma model ( MYOC Y435H, OPTN E50K and PMEL gene mutations), cataract model ( GJA8, KPNA4, C- MAF, AQP5 and PIKFYVE gene mutations), Leber congenital amaurosis animal model ( KCNJ13 and LCA5 gene mutations), retinblastoma animal model ( RB1/ RBL gene mutations) and retinitis pigmentosa models ( HKDC1, C8ORF37, CERKL, PRCD, ASRGL1, LRAT and PDE6B gene mutations) have been constructed by using this technology.The role of MFRP, CPAMD8, Pax6, and FREM genes in animal eye development has been further confirmed via this technology.The application of CRISPR/Cas9 gene editing technology in the construction of animal models of ophthalmic diseases was reviewed in this article.
ABSTRACT
With the development of technology and instruments, more and more giant liver tumors have been resected under laparoscopy. Compared with traditional approach hepatectomy, anterior hepatectomy is more suitable for laparoscopic resection of huge liver tumors, and it is also more in line with the " tumor-free principle" when it is used in the resection of liver malignant tumors. Our team summarized the experiences and lessons of laparoscopic hepatectomy and communicated with domestic and foreign experts to form a set of single center standardized process of laparoscopic anterior right hepatectomy, which is summarized as follows.
ABSTRACT
Objective@#To investigate the clinical efficacy of radical resection for stage T3 gallbladder cancer and prognostic factors.@*Methods@#The retrospective case-control study was conducted. The clinico-pathological data of 87 patients with T3 gallbladder cancer who were admitted to Tianjin Medical University Cancer Institute and Hospital from January 2005 to June 2016 were collected. There were 44 males and 43 females, aged 29-79 years, with a median age of 61 years. According to the different preoperative pathological classification and intraoperative exploration of gallbladder cancer, corresponding surgeries were performed. Observation indicators: (1) surgical and postoperative conditions; (2) clinical efficacy of stage T3 gallbladder cancer and prognostic factors analysis; (3) clinical efficacy of stage T3 gallbladder adenocarcinoma and prognostic factors analysis; (4) clinical efficacy of stage T3 gallbladder adenosquamous carcinoma and prognostic factors analysis. Follow-up by outpatient examination or telephone interview was performed to detect the postoperative survival of patients up to June 2018. Measurement data with skewed distribution were represented as M (range), and count data were described as absolute numbers. Survival curve, survival time and survival rate were drawn and calculated by the Kaplan-Meier method. Survival analysis was performed by the Log-rank test. Univariate analysis was performed using the Log-rank test and multivariate analysis using the COX proportional hazard model.@*Results@#(1) Surgical and postoperative conditions: all the 87 patients underwent radical resection of gallbladder cancer, including 29 cases of hepatic wedge resection and 58 cases of extended hepatectomy. Of the 87 patients, 42 underwent standard lymph node dissection and 45 underwent enlarged lymph node dissection. There were 27 cases receiving extrahepatic bile duct reconstruction. The postoperative pathological results of 87 patients showed that 64 were diagnosed with gallbladder adenocarcinoma and 23 were diagnosed with gallbladder adenosquamous carcinoma. There were 59 cases comorbid with liver invasion and 3 cases comorbid with vascular invasion. The marginal histopathological examination showed negative margin in 63 cases and positive margin in 24 cases. The degree of tumor differentiation: there were 23 patients with highly differentiated tumor and 64 with poorly differentiated tumor. Of the 87 patients, 43 received postoperative adjuvant therapy and 44 didn′t receive adjuvant therapy. (2) Clinical efficacy of stage T3 gallbladder cancer and prognostic factors analysis. ① All the 87 patients were followed up for 1.8-128.0 months, with a median follow-up time of 26.3 months. All the 87 patients had survived for 1.1-82.7 months, with a median time of 20.1 months. The 2-year overall survival rate of patients was 59.8%, and the 2-year disease-free survival rate was 49.4%. ② Univariate analysis showed that preoperative alkaline phosphatase (ALP) level, tumor diameter, pathological type of tumor, lymph node metastasis, and range of hepatectomy were associated factors for the postoperative 2-year overall survival rate of patients (χ2=5.451, 4.900, 8.256, 4.419, 5.858, P<0.05), and pathological type of tumor, lymph node metastasis, and range of hepatectomy were associated factors for the postoperative 2-year disease-free survival rate of patients (χ2=5.828, 6.968, 4.077, P<0.05). Multivariate analysis showed that preoperative ALP level, tumor diameter, and lymph node metastasis were independent factors influencing the postoperative 2-year overall survival rate of patients [hazard ratio (HR)=2.539, 2.619, 2.201, 95% confidence interval (CI) : 1.174-5.491, 1.209-5.673, 1.104-4.391, P<0.05)]; pathological type of tumor and lymph node metastasis were independent factors influencing the postoperative 2-year disease-free survival rate of patients (HR=2.254, 2.296, 95%CI: 1.170-4.344, 1.206-4.374, P<0.05). ③ Survival analysis: pathological type of tumor was an associated factor for the postoperative 2-year overall survival rate and 2-year disease-free survival rate of patients. Of the 87 patients with T3 gallbladder cancer, there was no significant difference in the postoperative 2-year overall survival rate between the 64 patients with gallbladder adenocarcinoma and 23 with gallbladder adenosquamous carcinoma (68.8% vs. 34.8%, χ2=8.256, P>0.05), but a significant difference in the postoperative 2-year disease-free survival rate between them (56.3% vs. 30.4%, χ2=5.828, P<0.05). (3) Clinical efficacy of stage T3 gallbladder adenocarcinoma and prognostic factors analysis. ① Sixty-four patients with gallbladder adenocarcinoma had the median survival time of 23.1 months, with a range from 3.2 to 82.7 months. The postoperative 2-year overall survival rate was 68.8%, and the postoperative 2-year disease-free survival rate was 56.3%. ② For the 64 patients with T3 stage gallbladder adenocarcinoma, univariate analysis showed that preoperative CA19-9 level and range of lymph node dissection were associated factors for the postoperative 2-year overall survival rate (χ2=4.012, 8.837, P<0.05). The range of lymph node dissection was an associated factor for the postoperative 2-year disease-free survival rate (χ2=6.361, P<0.05). Multivariate analysis showed that range of lymph node dissection was an independant factor for both the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate (HR=0.244, 0.382, 95%CI: 0.088-0.674, 0.176-0.831, P<0.05). ③ Survival analysis: range of lymph node dissection was an associated factor for both the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate of patients. Of the 64 patients with T3 stage gallbladder adenocarcinoma, the postoperative 2-year overall survival rate and disease-free survival rate of patients undergoing enlarged lymph node dissection were 84.8% and 69.7%, versus 51.6% and 41.9% of the patients undergoing standard lymph node dissection (χ2=8.837, 6.361, P<0.05). (4)Clinical efficacy of stage T3 gallbladder adenosquamous carcinoma and prognostic factors analysis. ① Twenty-three patients with gallbladder adenosquamous carcinoma had the median survival time of 13.2 months, with a range from 1.1 to 70.3 months. The postoperative 2-year overall survival rate was 34.8%, and the postoperative 2-year disease-free survival rate was 30.4%. ② For the 23 patients with T3 stage gallbladder adenosquamous carcinoma, univariate analysis showed that preoperative ALP level, lymph node metastasis, range of hepatectomy, and extrahepatic bile duct reconstruction were associated factors for the postoperative 2-year overall survival rate of patients (χ2=5.288, 4.574, 12.960, 4.106, P<0.05). The lymph node metastasis and range of hepatectomy were associated factors for the postoperative 2-year disease-free survival rate of patients (χ2=7.364, 10.582, P<0.05). Multivariate analysis showed that range of hepatectomy was an independant factor for both the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate (HR=0.102, 0.153, 95%CI: 0.012-0.880, 0.033-0.718, P<0.05). ③ Survival analysis: range of hepatectomy was an independant factor for both the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate of patients. Of the 23 patients with T3 stage gallbladder adenosquamous carcinoma, the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate of patients undergoing extended hepatectomy were 87.5% and 75.0%, versus 6.7% and 6.7% of the patients undergoing hepatic wedge resection (χ2=12.960, 10.528, P<0.05).@*Conclusions@#Lymph node metastasis is an independent factor influencing the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate of patients with T3 stage gallbladder cancer. The range of lymph node dissection is an independent factor for the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate of patients with stage T3 gallbladder adenocarcinoma. Range of hepatectomy is an independent factor for the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate of patients with stage T3 gallbladder adenosquamous carcinoma. Patients with gallbladder adenocarcinoma should undergo enlarged lymph node dissection, and patients with gallbladder adenosquamous carcinoma need to undergo extended hepatectomy.

ABSTRACT
Foodborne disease is one of the most important public health issues worldwide. China faces various and unprecedented challenges in all aspects of the food chain. Data from laboratory-based foodborne disease surveillance systems from 2013 to 2016, as well as different regions and ages, can be found along with differences in the patterns of pathogens detected with diverse characteristics. Vibrio parahaemolyticus has been the leading cause of infectious diarrhea in China, especially among adults in coastal regions. Salmonella has been a serious and widely distributed pathogen responsible for substantial socioeconomic burden. Shigella was mostly identified in Northwest China and the inland province (Henan) with less-developed regions among children under 5 years. Data from foodborne disease outbreak reporting system from 2011 to 2016 showed that poisonous animals and plant factors responsible for most deaths were poisonous mushrooms (54.7%) in remote districts in southwest regions. The biological hazard that caused most cases reported (42.3%) was attributed to V. parahaemolyticus, the leading cause of foodborne outbreaks. In this review, we summarize the recent monitoring approach to foodborne diseases in China and compare the results with those in developed countries.
