60Co-γ ray irradiation has the unique advantages of high efficiency, strong penetration, operation at room temperature and no residue, which has been widely used in the sterilization of Chinese medicinal materials, decoction pieces, Chinese patent medicine. However, the irradiation effect may cause changes in the content of chemical components in Chinese materia medica or the emergence of new radiolysis products, leading to reduced efficacy and uncontrollable safety risks. This paper reviewed the relevant literature at home and abroad, summarized the effect of irradiation sterilization on various types of chemical compositions of Chinese medicinal materials and their preparations, and analyzed and explored the rule of change. The results showed that the content changes of various chemical components in Chinese materia medica after 60Co-γ ray irradiation sterilization varied. The contents of most flavonoids, terpenoids, phenylpropanoids and quinones decreased after irradiation, and the degree of decrease increased with the elevated irradiation dose. The contents of lignans, alkaloids, isoflavones and some terpenoids did not change significantly before and after irradiation, while the content changes of triterpenoid saponins, dihydroflavonols, chalcones, sugars and glycosides after irradiation were not yet uniform. Therefore, it is recommended to pay attention to the compositional changes of irradiated Chinese medicines, strengthen the research on the standards of irradiated Chinese medicines, and standardize the irradiation and sterilization of Chinese medicines in order to promote the healthy and rational application of irradiated Chinese medicines.

OBJECTIVE:
Objective To investigate the relationship between cervical disc herniation and C0-C2 Cobb angle.
METHODS:
The clinical data of 301 patients with cervical disc herniation from 2020 to 2024 were retrospectively analyzed. The median value of C0-C2 Cobb angle measurements from 301 patients was used as the boundary, cervical disc herniation patients were divided into two groups, C0-C2 Cobb angle <28.50 group and 151 patients with C0-C2 Cobb angle≥28.50 group. Among them, 150 patients in C0-C2 Cobb angle <28.50 group included 53 males and 97 females, aged 23 to 76 (57.32±12.55) years, with a disease duration of 7 to 19 (13.81±5.32) months;the othor 151 patients with C0-C2 Cobb angle≥28.50 group including 61 males and 90 females, aged 25 to 74 (56.86±12.51) years, with a disease duration of 8 to 18 (14.13±5.56) months. The cervical lordosis angle (C0-C2 Cobb angle and C2-C7 Cobb angle), T1 inclination slope (T1S) and cervical sagittal axial distance (C2-C7 SVA) were measured on the lateral cervical radiographs. The correlation between C0-C2 Cobb angle and cervical disc herniation range, protrusion position, average protrusion size and other parameters was analyzed.
RESULTS:
When the C0-C2 Cobb angle<28.50°, the average protrusion size was (2.21±0.56) mm, the C2-C7 Cobb angle was (19.92±12.06)° and the C2-C7 SVA was (1.10±1.20) mm. When the C0-C2 Cobb angle≥28.50°, the average protrusion size was (2.38±0.60) mm, the C2-C7 Cobb angle was (12.01±13.09 )°, the C2-C7 SVA was (1.53±1.36) mm, and the difference was statistically significant (P<0.05). Between the two groups of patients with C0-C2 Cobb angle < 28.50° and C0-C2 Cobb angle≥28.50°, there were significant differences in the size of C3,4, C4,5, C5,6, C6,7, C7, T1 disc herniation in single segment (P<0.05 ). C0-C2 Cobb angle was correlated with age(r=-0.135, P<0.05 ), C2-C7 Cobb angle (r=-0.382, P<0.01 ), C2-C7 SVA (r=0.293, P<0.01), average protrusion size (r=0.139, P<0.05), and the size of C3,4 (r=0.215, P<0.01 ), C4,5 (r=0.176, P<0.01 ), C5,6 (r=0.144, P<0.05 ), C6,7 (r=0.158, P<0.05 ), C7T1 (r=0.535, P<0.05) disc herniation.
CONCLUSION
There is a positive correlation between C0-C2 Cobb angle and the size of cervical disc herniation. C0-C2 Cobb angle can reflect the degree of cervical disc herniation. Previous studies have shown that the biomechanical changes between C0-C2 Cobb angle, C2-C7 Cobb angle, C2-C7 SVA and cervical extensor muscle group may be risk factors for accelerating cervical disc herniation and this may be one of the mechanisms that C0-C2 Cobb angle is positively correlated with the size of cervical disc herniation.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Background Other infectious diarrhea (OID) refers to infectious diarrhea other than cholera, dysentery, and typhoid/paratyphoid fever. In the global climate change context, frequent extreme temperature events pose a significant threat to population health, yet the association between extreme temperatures and OID remains unclear. Objective To understand the impact of extreme temperature events on the incidence of OID in Taizhou region, and provide a scientific basis for formulating targeted public health intervention strategies. Methods Case data of OID from 2016 to 2024 and meteorological and pollutant data of Taizhou, Zhejiang during the same period were collected. The case data were derived from National Notifiable Infectious Diseases Reporting System, while the meteorological data and pollutant data were obtained from National Meteorological Science Data Center and Taizhou Ecology and Environment Bureau, respectively. An extreme heat event is defined as a period of two or more consecutive days in the warm season during which the daily mean temperature exceeds the 90th percentile value for that season. Similarly, an extreme cold event is defined as a period of two or more consecutive days in the cold season during which the daily mean temperature falls below the 10th percentile value. A distributed lag nonlinear model based on Poisson regression was used to assess the impact of extreme temperatures on OID incidence. Furthermore, subgroup analyses were conducted by gender and age. Results From 2016 to 2024, a total of 108 670 OID cases were reported in Taizhou, with higher incidence in males (61 253 cases) than females (47 417 cases). In terms of single-day lag effect, exposure to extreme cold presented an inverted U-shaped risk pattern: a significant risk effect began to emerge on the 4th day after exposure, continued to rise, and reached a peak on the 7th day (RR=1.044, 95%CI: 1.029, 1.058), whereas extreme heat had no significant impact. In terms of cumulative lag effect, exposure to extreme cold presented a J-shaped cumulative effect curve: short-term exposure (0-2 days) showed no risk effect, but as time extended (0-9 days), a risk effect emerged and reached the maximum risk value during the 0-12 d cumulative period (RR=1.243, 95%CI: 1.057, 1.461). In contrast, extreme heat had no cumulative lag effect. The subgroup analysis revealed that under extreme cold exposure, the single-day lag effects for both males and females exhibited an inverted U-shaped curve, with the risk peaking on day 7 for males (RR=1.045, 95%CI: 1.026, 1.065) and day 8 for females (RR=1.041, 95%CI: 1.019, 1.064). The risk pattern in the 1-5 years age group was similar to that of the overall population but with a higher effect size (RR=1.063, 95%CI: 1.041, 1.085). In terms of the cumulative lag effects, the cumulative risk curves for both males and females under extreme cold exposure showed a J-shaped pattern with varied risk profiles. Significant variations in risk patterns were observed across different age groups. No significant cumulative lag effects were observed for extreme heat exposure in any subgroup. Conclusion Extreme cold can increase the incidence of OID in Taizhou, and the risk effects are heterogeneous among different groups. No risk effect is observed for extreme heat.

The combination of sourness,bitterness,sweetness,pungency,and saltness results in different effects.Through the analysis of the theory of combining five flavours in Fu Qingzhu's Obstetrics and Gynecology,this article explores its application in formulation ideas and the characteristics of Chinese medication,summarized as"primarily sweet,with all four flavors harmonized".FU Qingzhu emphasizes the central role of sweet-flavour medicine in facilitating conception,while incorporating the other four flavours in synergy.For instance,sweet and pungent flavours can boost yang energy,eliminating chilliness and warming the uterus;sour and sweet flavours can nourish yin essence and protect the uterus;bitter and sweet flavours can tonify yin,supporting the kidneys and moistening the uterus;and pungent and salty flavours can eliminate stasis,regenerate blood,and enhance uterine functions.By flexibly utilizing the flavours and meridian affinity of traditional Chinese medicine,along with the theory of combining five flavours,it is possible to enhance drug compatibility,deepen the theoretical connotation of Chinese formulas,and regulate the uterus from both yin and yang aspects to facilitate conception.FU Qingzhu's integration of multiple Chinese formulas into a single formula allows for comprehensive treatment.Clear differentiation of dosages within the formula highlights the primary and secondary relationships of traditional Chinese medicines.Additionally,the utilization of pharmaceutical processing techniques optimizes efficacy and regulates meridians and collaterals.This article explores FU Qingzhu's application of the"pure and harmonious traditional Chinese medicines"theory.His prescription thinking enables the attainment of multi-level therapeutic effects,which greatly benefits the optimization of traditional Chinese medicine fertility assistance programs and increases pregnancy rates among infertility patients.

Objective:To investigate the factors that influence the prolongation of gestation following emergency cervical cerclage.Methods:This retrospective study included 88 singleton pregnant women who were diagnosed with cervical incompetence and underwent emergency cervical cerclage at 12-26 weeks of gestation in the Jiaxing Maternity and Child Health Care Hospital from January 1, 2019 to September 1, 2022. The participants who delivered after 28 gestational weeks were assigned to the success group ( n=77), while those who delivered or miscarried before 28 gestational weeks were assigned to the failure group ( n=11). Two independent sample t-test or Mann-Whitney U test was used for comparison between groups. The factors affecting the prolongation of gestation after the procedure were selected by univariate analysis and multiple regression equations. Results:The success rate (delivery rate≥28 weeks) was 87.5% (77/88). There were six women delivered at 28-31 +6 weeks of gestation (6/77, 7.8%), two at 32-33 +6 weeks of gestation (2/77, 2.6%), 16 at 34-36 +6 weeks of gestation (16/77, 20.8%), and 53 at 37 weeks of gestation or later (53/77, 68.8%). Multiple regression analysis indicated that three times of early pregnancy miscarriage ( β=-5.1, 95% CI: -9.5 to -0.7), five times of early pregnancy miscarriage ( β=-11.8, 95% CI: -22.1 to -1.6), had two live births ( β=-6.9, 95% CI: -12.9 to -0.9), gestational age at cerclage ( β=-0.6, 95% CI: -1.0 to -0.3), external cervical os dilation<15 mm ( β=-12.1, 95% CI: -22.5 to -1.8) and ≥15 mm before cerclage ( β=-11.0, 95% CI: -21.4 to -0.71) were factors affecting the prolongation of gestation after cerclage. After adjusting for maternal age and weight before emergency cervical cerclage, five times of early pregnancy miscarriage ( β=-18.1, 95% CI: -28.3 to -7.8), gestational age at cerclage ( β=-0.6, 95% CI: -1.0 to -0.3), and external cervical os dilation≥15 mm before cerclage ( β=-11.4, 95% CI:-21.2 to -1.6) remained the significant influencing factors (all P<0.05). Conclusion:The number of early pregnancy miscarriages, gestational age at cerclage, and the width of external cervical os dilation before cerclage≥15 mm are the factors that influence the prolongation of gestation after the emergency cervical cerclage procedure.
