ObjectiveTo explore the effect of different drying conditions on the appearance and intrinsic quality indicators of Pinelliae Rhizoma for screening suitable drying conditions， so as to provide reference for its standardized production and quality evaluation. MethodsDifferent dried samples of Pinelliae Rhizoma were prepared by lime-assisted sweating method and intermittent drying method. Visual analysis was employed to measure the color brightness values（L^*） of the surface， cross-section and powder of the samples， texture analyzer was used to determine the hardness of the samples under different drying conditions. The total starch content was calculated by measuring the contents of amylose and amylopectin in the samples with ultraviolet-visible spectroscopy. High performance liquid chromatography（HPLC） was used to determine the contents of seven nucleoside components（uracil， hypoxanthine， uridine， inosine， guanosine， β-thymidine and adenosine） in the samples. Pearson correlation analysis was conducted to explore the correlation between the external characteristics and intrinsic indicators of the different dried samples. Principal component analysis（PCA） was used to comprehensively rank the data of various indicators， and partial least squares-discriminant analysis（PLS-DA） was used to screen differential components with variable importance in the projection（VIP） value>1. Furthermore， the difference between the optimal drying condition for Pinelliae Rhizoma and the traditional sun-drying method was explored by independent samples t-test. ResultsWith the increase of temperature， the color of the intermittently dried samples gradually deepened， while their hardness gradually decreased. Concurrently， the contents of extract， total starch， uridine and adenosine exhibited an upward trend， whereas the contents of uracil， hypoxanthine and inosine displayed a downward trajectory. Compared with the intermittent drying group， the content of extract in the samples subjected to lime-assisted sweating increased. With the increase of lime dose， the hardness and the total content of nucleoside components in the samples showed a downward trend， while the total starch content showed an upward trend. Correlation analysis showed that the comprehensive score of L^* was negatively correlated with the contents of uracil， hypoxanthine and inosine， and positively correlated with the contents of uridine， guanosine and adenosine. Hardness was negatively correlated with adenosine content， and positively correlated with the contents of inosine， uracil and hypoxanthine. Through comprehensive consideration and comprehensive score of principal components， the method of 5% lime-mixed sweating for 6 days emerged as the top-ranking approach. Except for the extract， the results of independent samples t-test showed that there was no significant difference between the 5% lime-mixed sweating for 6 days and the traditional sun-drying in terms of other content indicators. ConclusionThe whiteness and firmness of Pinelliae Rhizoma exhibit significant correlations with its chemical composition， while uridine， uracil， guanosine， adenosine and inosine are the key constituents responsible for the quality difference of Pinelliae Rhizoma under different drying conditions. The lime-assisted sweating method optimized in this study can be proposed as a viable alternative to the traditional sun-drying method. This method not only ensures the quality of the medicinal material but also effectively reduces the drying time and prevents mold contamination， which provides a valuable reference for the standardization of drying conditions and the establishment of quality evaluation criteria for Pinelliae Rhizoma.

Objective To examine the toxicity and sublethal effects of calcium cyanamide against susceptible isolates of Aedes albopictus, so as to provide insights into rational use of calcium cyanamide for integrated management of Ae. albopictus. Methods The sublethal concentrations [30% lethal concentration (LC₃₀) and median lethal concentration (LC₅₀)] of calcium cyana mide against susceptible strains of Ae. albopictus were determined using the larval immersion test. With 100 mL of dechlorinated water as the control group, after the larvae of susceptible strains of Ae. albopictus were immersed in calcium cyanamide for 24 hours, the pupation rate, pupation duration, emergence rate, number of eggs laid, percentage of eggs hatched, and lifespan of Ae. albopictus were calculated and compared post-treatment with calcium cyanamide at different sublethal concentrations. The midgut tissues of larvae of susceptible strains of Ae. albopictus treated with 100 mg/L calcium cyanamide were sampled for pathological sectioning to observe midgut tissue damages. To evaluate the residual activity, 100 larvae of susceptible strains of Ae. albopictus were treated with 200 mg/L and 500 mg/L calcium cyanamide, and the mortality of larvae was calculated every 24 hour, with dead larvae replaced until no larval death. Results The regression equation for the toxicity of calcium cyanamide against larvae of susceptible strains of Ae. albopictus was y = -9.441 + 4.657x, with an LC₅₀ of 106.42 mg/L [95% confidence interval (CI): (94.64, 118.36) mg/L] and an LC₃₀ of 82.17 mg/L [95% CI: (94.64, 118.36) mg/L], respectively. After larvae of susceptible strains of Ae. albopictus were treated with sublethal concentrations (LC₃₀ and LC₅₀) of calcium cyanamide for 24 hours, there were reduced pupation and emergence rates of larvae (all P values < 0.000 1), prolonged pupal stage (both P values < 0.000 1), reduced numbers of eggs laid by survival female Ae. albopictus (both P values < 0.000 1), reduced percentages of eggs hatched by Ae. albopictus eggs (both P values < 0.000 1), and reduced median survival period of survival female Ae. albopictus (χ² = 9.36 and 20.33, both P values < 0.01) in the LC₃₀ and LC₅₀ groups relative to the control group. There was a numerical decline in the median survival period of survival female Ae. albopictus in the LC₃₀ groups relative to the control group (χ² = 2.42, P > 0.05), and there was a significant decline in the median survival period of survival female Ae. albopictus in the LC₅₀ group relative to the control group (χ² = 11.42, P < 0.01). Histopathological examinations showed severe damages to the midgut tissues of larvae of susceptible strains of Ae. albopictus, and residual activity assay revealed that the mortality of larvae of susceptible strains of Ae. albopictus was both 0 on day 32 post-treatment with calcium cyanamide at a concentration of 200 mg/L and on day 70 post-treatment with calcium cyanamide at a concentration of 500 mg/L, showing complete loss of the larvicidal activity of calcium cyanamide. Conclusions Calcium cyanamide is highly toxic against susceptible strains of Ae. albopictus, and calcium cyanamide at sublethal concentrations (LC₃₀ and LC₅₀) may inhibit growth, development, and reproductive capability of susceptible strains of Ae. albopictus, and shorten the lifespan of adult mosquitoes.

Objective:To examine the attentional processing of verbal emotional information in college students with subclinical depression.Methods:Fifty college students were recruited(24 with subclinical depression group and 26 in the control group)were recruited from a university in Liaoning Province to investigate the atten-tional bias of subclinically depressed college students towards verbal emotional information(experiment 1).In addi-tion,48 college students(20 with subclinical depression and 28 in the control group)were recruited to investigate the attention disengagement of subclinically depressed college students from verbal emotional information(experi-ment 2).In experiment 1,two groups passively viewed words and recorded the eye movement data of emotional words.In experiment 2,two groups were asked to watch the emotional word-neutral word pair.When color borders were presented around neutral words,the attention disengagement latency that was the time taken by the eye saccade from emotional words to neutral words was recorded.Results:The results of experiment 1 showed that the total fix-ation duration of negative words in the subclinical depression group was longer than that in the control group(P＜0.01).The results of experiment 2 showed that attention disengagement latency of negative words in the subclinical depression group was longer than that in the control group(P＜0.05).Conclusion:College students with subclini-cal depression exhibit attentional bias towards negative verbal information and difficulties in attentional disengage-ment.

Ductal carcinoma in situ of the breast (DCIS) most commonly manifests as asymptomatic calcifications at mammography. The most common manifestation of MRI is nonmass enhancement. The ultrasound mainly presents as a hypoechoic irregular hypervascular mass without posterior features. Core-needle biopsy is a commonly used method for preoperative diagnosis of DCIS. Due to differences in needle type and sample size, there is a certain degree of pathological upgrading of the lesion. In recent years, there has been controversy over the diagnosis and treatment of DCIS. With the development of breast disease diagnostic technology, advances in digital breast tomography, artificial intelligence, and radiomics are expected to help DCIS management and address issues such as overdiagnosis.

BACKGROUND:At present,measurement osteotomy technique and gap balance technique are the two main surgical methods in total knee arthroplasty.Both methods have their advantages and disadvantages.By adjusting the osteotomy angle,the gap balance technique can reduce the release of soft tissue and obtain a more balanced flexion and extension space.The clinical efficacy of gap balance technique is superior,but this surgical method lacks tools and is easily influenced by the surgeon's surgical experience and subjective judgment,with more errors.Measurement osteotomy technique has a short learning curve,but it relies on anatomic markers and is prone to many complications due to inaccurate positioning.In recent years,many instrument companies have successively developed and launched tools that can improve the quality of surgery.However,there are still few reports about the tool. OBJECTIVE:To compare the clinical efficacy of gap balance technique and measurement osteotomy technique under Offset Repo-Tensor in total knee arthroplasty,and explore the value of Offset Repo-Tensor in total knee arthroplasty. METHODS:The medical records of 85 patients with total knee arthroplasty were collected and divided into two groups according to the operation method.Group A consisted of 44 patients who underwent total knee arthroplasty using a gap balance technique combined with Offset Repo-Tensor.Group B consisted of 41 patients who underwent total knee arthroplasty using measurement osteotomy technique.Surgical time,American Knee Society Score,knee range of motion,changes in lower limb alignment,and postoperative complications were compared between the two groups to evaluate the clinical efficacy of gap balance technique combined with Offset Repo-Tensors in total knee arthroplasty. RESULTS AND CONCLUSION:(1)All 85 patients were followed up.(2)Postoperative knee range of motion in both groups was higher than that before surgery(P<0.05),and the improvement in group A was more significant than that in group B(P<0.05).(3)American Knee Society Score in both groups after surgery was higher than that before surgery(P<0.05),and the American Knee Society Score in group A was higher than that in group B at 2 weeks,1,3 months,and the last follow-up(P<0.05).(4)The operation time of group A was slightly shorter than that of group B,but the difference was not significant(P>0.05).(5)The lower limb alignment in both groups was improved after operation,but there was no significant difference between the two groups(P>0.05).(6)The complication rate of group A(2%)was lower than that of group B(7%),but there was no significant difference between the two groups(P>0.05).(7)It is indicated that compared with the measurement osteotomy technique,the combination of Offset Repo-Tensor and gap balance technique can elevate the clinical effect and improve the function and motion range of the knee joint.

OBJECTIVE: Evidence that long-term exposure to ambient air pollution increases mortality among older adults, particularly those residing in low-level air pollution locations, remains scarce. This study investigated the potential links between long-term low-level air pollution exposure and mortality among Chinese older adults. METHODS: A population-based study with 317,464 individuals aged ≥ 65 years was conducted in Shenzhen, China during 2018 and 2020. Logistic regression models were used to analyze the associations between long-term exposure to air pollution and all-cause mortality, as the primary outcome, as well as non-accidental, cancer and cardiovascular mortality. RESULTS: Significant associations of PM ₁, PM _2.5, PM ₁₀, SO ₂, CO, and O ₃ exposures with a higher risk of all-cause mortality were found. Adjusted odds ratio ( OR) for each 1 µg/m ³ increment was 1.49 [95% confidence interval ( CI): 1.46, 1.53] for PM ₁, 1.30 (1.27, 1.32) for PM _2.5, 1.05 (1.04, 1.06) for PM ₁₀, 5.84 (5.39, 6.32) for SO ₂, 1.04 (1.04, 1.05) for CO, and 1.02 (1.00, 1.03) for O ₃, respectively. Long-term PM ₁, PM _2.5, PM ₁₀, SO ₂, and CO exposures also elevated the risks of non-accidental, cancer and cardiovascular mortality. CONCLUSION Long-term low-level air pollution exposure was associated with an increased mortality risk among Chinese older adults.
