Objective: To investigate trends in incidence and mortality of colorectal cancer in Nantong City, Jiangsu Province from 2013 to 2022. Methods: Data on incidence and mortality of colorectal cancer from 2013 to 2022 in Nantong City were collected through the Nantong City cancer registry. The crude incidence, crude mortality, average age at onset, and average age at death of colorectal cancer were calculated. Chinese population-standardized incidence, Chinese population-standardized mortality, Chinese population-standardized average age at onset and Chinese population-standardized average age at death were calculated using the age structure of the standard population from the Fifth National Population Census in 2000. Trends in incidence and mortality of lung cancer from 2013 to 2022 were evaluated using average annual percent change (AAPC). Trends in the Chinese population-standardized average age at onset and Chinese population-standardized average age at death of lung cancer from 2013 to 2022 were evaluated using the linear regression model. Results: From 2013 to 2022, the crude incidence and Chinese population-standardized incidence of colorectal cancer in Nantong City increased from 33.63/105 and 16.05/105 to 53.82/105 and 19.62/105, respectively, showing upward trends (AAPC=5.665% and 2.467%, both P<0.05). The crude mortality increased from 15.99/105 in 2013 to 25.65/105 in 2022, also showing an upward trend (AAPC=5.514%, P<0.05), while no statistically significant trend was found in the Chinese population-standardized mortality (P>0.05). The Chinese population-standardized incidence of colorectal cancer showed upward trends in both males and females (AAPC=2.666% and 1.790%, both P<0.05). The Chinese population-standardized mortality showed an upward trend in males (AAPC=1.966%, P<0.05), but no statistically significant trend was found in females (P>0.05). The crude incidence of colorectal cancer in the groups aged 40-<50 years, 50-<60 years, 60-<70 years, 70-<80 years, and ≥80 years showed upward trends (AAPC=4.045%, 2.833%, 2.300%, 1.948%, and 1.775%, all P<0.05), and the crude mortality in the group aged ≥80 years showed an upward trend (AAPC=3.240%, P<0.05). The average age at onset of colorectal cancer increased at an annual average of 0.156 years (P<0.05), while the trend in the Chinese population-standardized average age at onset was not statistically significant (P>0.05). The average age at death and the Chinese population-standardized average age at death increased at an annual average of 0.325 and 0.153 years, respectively (both P<0.05). Conclusions From 2013 to 2022, both the crude incidence and mortality of colorectal cancer in Nantong City showed upward trends. Males and individuals aged ≥40 years faced a higher risk of both incidence and mortality. It is recommended to implement comprehensive prevention and control measures targeting these high-risk populations to reduce the burden of colorectal cancer.

Objective:To compare the therapeutic effects of intramedullary nail fixation, simple tibial plate fixation, and tibial plate + posterior-to-anterior screw fixation in the surgical treatment of lower 1/3 spiral fracture of the tibia combined with posterior malleolar fracture.Methods:A retrospective study was conducted to analyze the clinical data of 78 patients with lower 1/3 spiral fracture of the tibia combined with posterior malleolar fracture who had been treated at Department of Orthopedics, The Hospital Affiliated to Qingdao University from June 2015 to June 2022. There were 46 males and 32 females with an age of (48.9±14.6) years. The patients were divided into 3 groups according to their fixation methods. Group A (18 patients) underwent simple intramedullary nail fixation, group B (40 patients) simple tibial plate fixation, and group C (20 patients) tibial plate fixation for tibial fractures and posterior-to-anterior screw fixation for posterior malleolar fractures. The operation time, intraoperative blood loss, fracture union time, postoperative complications, as well as ankle-hindfoot scores of American Orthopaedic Foot and Ankle Society (AOFAS) and Baird-Jackson scores at pre- and post-operation were compared among the 3 groups.Results:The differences in the preoperative baseline data were not statistically significant among the 3 groups, indicating comparability ( P>0.05). All patients were followed up for (24.9±10.1) months. The fracture union time in Group A was 14.0(13.0, 14.0) weeks, significantly longer than that in groups B and C [13 (13, 14) weeks] ( P<0.05). The AOFAS ankle-hindfoot score and Baird-Jackson score at the last postoperative follow-up in all patients were better than those before surgery ( P<0.05). The AOFAS ankle-hindfoot scores at the last follow-up in groups B and C [95.5 (86.0, 96.0) points and 96.0 (89.5, 98.5) points] were significantly higher than that in group A [86.5 (78.0, 93.0) points] ( P<0.05), and the Baird-Jackson scores at the last follow-up in groups B and C [93.0 (88.8, 95.0) points and 95.0 (91.0, 98.0) points] were also significantly higher than that in group A [86.0 (78.0, 89.5) points] ( P<0.05). All the 7 cases of complications (3 ones of poor fracture union and 4 ones of anterior knee pain) were observed in group A. Conclusion:In the surgical treatment of lower 1/3 spiral fracture of the tibia combined with posterior malleolar fracture, tibial plate fixation and tibial plate + posterior-to-anterior screw fixation can achieved better therapeutic effects than intramedullary nail fixation.

In recent years, the combined surgery of phacoemulsification, intraocular lens implantation, and goniosychialysis has gradually emerged as a primary and effective approach in treating primary angle-closure glaucoma with cataracts. However, with the continuous progress of medical technology, postoperative intraocular pressure control is no longer the sole pursuit. Patients increasingly aspire to achieve higher postoperative visual quality. In order to ensure that patients attain a better refractive status and higher visual quality postoperatively, it is essential to minimize the negative impact caused by primary angle-closure glaucoma. This involves personalized selection of different intraocular lenses or calculation formulas,etc. Evaluation metrics for visual quality encompass visual acuity, contrast sensitivity, higher-order aberrations, subjective perception, etc. Therefore, this paper provides a comprehensive review of postoperative refractive shift, higher-order aberrations, contrast sensitivity and their influencing factors, and the selection of intraocular lenses for patients undergoing combined surgery for primary angle-closure glaucoma with cataracts.

Objective To investigate the popularization of cardiopulmonary resuscitation(CPR)knowledge and science popularization needs among urban and rural residents in Tonghai County,Yuxi City,Yunnan Province,so as to explore the establishment of an efficient and appropriate science popularization model.Methods A total of 300 residents aged 15-60 years old were selected from Tonghai County,Yuxi City,Yunnan Province using stratified and simple random sampling methods.A self-designed questionnaire was used to conduct an anonymous questionnaire survey.Results Only 20.3%of Tonghai County residents master CPR skills,and 26.2%of Tonghai County residents have never heard of CPR.There is a statistically significant difference in the awareness rate of CPR between rural residents and non-rural residents(P<0.01).There are differences in residents'age and CPR awareness(P<0.01),the age and CPR are inversely proportional.The residents have a higher willingness to perform chest compressions and mouth-to-mouth resuscitation on strangers,66.2%and 68.6%respectively.63.79%of residents have never attended relevant training.But 92.76%of the people said they were willing to participate in the relevant training when they learned the training news.Conclusion Residents in Tonghai County generally lack knowledge of CPR first aid,but the demand for first aid knowledge of residential CPR is high and the attitude towards rescue is positive.It is recommended that relevant departments increase CPR science popularization and training efforts,and popularize CPR into villages.

【Objective】 To analyze the correlation of HBV serological characteristics between non-reproducible reactivity (NRR) samples and occult hepatitis B virus infection (OBI) samples for blood screening. 【Methods】 A total of 144 samples with negative ELISA (HBV, HCV and HIV test) results and reactive nucleic acid tests(NAT) were collected from January 2021 to January 2023 in Anhui Blood Center, including 92 reactive samples by TMA method (combined ID-NAT) and 52 HBV DNA reactive samples by PCR method (ID-NAT). Supplementary differential testing and ID-NAT by PCR were performed on the reactive samples of the combined ID-NAT, samples that were non-reactive by both differential testing and ID-NAT by PCR were included in the NRR group, and samples that were reactive for HBV DNA detected by either method were included in the OBI group. Supplemented with HBsAg, anti-HBs, HBeAg, anti-HBe and anti-HBc tests, the differences in serological pattern and positive rate between NRR samples and OBI samples were analyzed. 【Results】 A total of 53 samples were negative for differential testing and ID-NAT and were included in the NRR group, 91 samples were detected as HBV DNA reactive in either method and were included in the OBI group. HBsAg and HBeAg were not detected by serological testing in either group. The detection rates of anti-HBs, anti-HBc and anti-HBe in the NRR group and the OBI group were 64.15% vs 47.25%, 86.79% vs 94.51%, 35.85% vs 52.75%, respectively. Comparison of serological patterns between the two groups: the most frequent pattern in the NRR group was anti-HBs (+ ) and anti-HBc (+ ) (32.08%), and the most frequent pattern in the OBI group was anti-HBe (+ ) and anti-HBc (+ ) (37.36%). 【Conclusion】 There were differences in some of the test results between the NRR samples and the OBI samples in HBV serological testing, and higher anti-HBc positive rate in the NRR samples suggests a higher possibility of HBV infection.

Pressure injury is a kind of chronic wound that is difficult to heal in clinical practice. The healing process often fails to proceed smoothly, which is one of the difficult problems in the field of clinical wound repair. At present, the wound treatment method has developed rapidly and has an obvious curative effect on stage 1 and 2 pressure injuries. There are fewer treatments for stage 3 and 4 pressure injuries, and surgical treatment is often used. However, surgical treatment has the risk of superimposed injury, which may aggravate the condition. In addition, the treatment effect needs to be improved. It is necessary to explore high-quality, minimally invasive, and low-cost solutions to solve this problem. This article reviews the definition, classification, formation mechanism, clinical manifestations, influencing factors, and treatment methods of pressure injury, aiming to provide a reference for the clinical treatment of pressure injury wounds.

ObjectiveTo compare the differences in resistance and structure of skin between acupoints and non-acupoints， and to study the difference in skin permeability characteristics of Corydalis Rhizoma total alkaloid patches （CTTP） after administration at Shenque acupoint and non-acupoint， so as to provide experimental support for its clinical acupoint application to prevent and treat chronic pain. MethodTaking corydaline （CD）， tetrahydropalmatine （THP） and corydalis L （CDL） as evaluation indexes， and the quantitative analysis was carried out by high performance liquid chromatography （HPLC）. The mobile phase was methanol-0.04 mol·L^-1 phosphoric acid aqueous solution （70∶30， pH 6.0 adjusted with triethylamine）， the detection wavelength was 281 nm. In vitro transdermal test in Franz diffusion cell and in vivo transdermal test were used to study the skin permeability characteristics of CTTP through Shenque acupoint and non-acupoint administration. At the same time， the skin resistance between Shenque acupoint and non-acupoint was measured before and after the administration， and the distribution of the drug in each layer of the skin was compared by freezing sectioning， and visual verification was performed with fluorescence inverted microscope. ResultAfter 24 h of administration， the results of in vivo and in vitro experiments showed that the cumulative permeation and retention of CD， THP and CDL at Shenque acupoint skin were higher than those at non-acupoint skin （P<0.05， P<0.01）， the skin resistance of Shenque acupoint was lower than that of non-acupoint at all time points. The fluorescence microscopic observation results showed that the drug content of each layer of the skin was all Shenque acupoint>non-acupoint， indicating that the skin of Shenque acupoint had better effect on drug penetration and storage than non-acupoint. ConclusionThe 24 h cumulative permeation and retention of CTTP in Shenque acupoint skin are higher than those in non-acupoint skin， and the mechanism may be related to the thin skin， low electrical resistance and large number of hair follicle bodies at Shenque acupoint.
