Objective: To investigate the distribution of IgM anti-A/B titers among group O whole blood donors in Jiangsu, establish a low-titer threshold, and analyze the demographic characteristics of low-titer donors, so as to provide data for recruiting low-titer group O whole blood (LTOWB) donors. Methods: Plasma samples from 1 009 group O whole blood donors were tested for IgM anti-A and anti-B titers using the microplate technique. The distribution of antibody titers was analyzed to establish a low-titer threshold. The distribution trends of titers across different demographic groups were also analyzed. Results: The peak titer for anti-A, anti-B were 64 (31.5%), 4 (23.8%), respectively, The proportion of donors with both anti-A and anti-B titers below 64 was 97.3% (982/1 009). The mean anti-A titer was higher than anti-B titer. Anti-A titers were higher in female donors than in male donors (P<0.05). The anti-A titers differed significantly among different age groups (P<0.05). However, no significant difference in titers was observed based on the number of donations (P>0.05). Conclusion: A titer of 64 can be used as the reference threshold of LTOWB in Jiangsu. Male donors of appropriate age are more suitable than female donors for establishing an emergency panel of LTOWB mobile donors.

OBJECTIVE:
To explore clinical effects of bone setting manipulation combined with pry reduction and Kirschner needle internal fixation in treating SandersⅡ-Ⅲ calcaneal fracture.
METHODS:
Clinical data of 52 patients with types Sanders Ⅱand Ⅲ calcaneal fracture (foot) treated with bone-setting manipulation combined with pry reduction and Kirscher needle internal fixation from July 2017 to July 2019 were retrospectively analyzed, including 43 males and 9 females, aged from 31 to 72 years old with an average of (50.83±10.48) years old; 15 patients with Sanders typeⅡ and 37 patients with Sanders type Ⅲ. The changes of Bühler angle, Gissane angle, calcaneus width and calcaneus height before operation and 24 months after operation were compared, and Maryland foot function score was performed to evaluate clinical effects.
RESULTS:
All patients were followed up from 24 to 60 months with an average of (41.50±9.86)months. The fracture healed normally and the healing time was (11.00±0.95) weeks. Bühler angle, Gissane angle, calcaneal bone width and calcaneal bone height were increased from (16.37±8.36)°, (96.27±9.62)°, (46.82±4.67) mm, (38.41±3.58) mm before operation to (31.48±8.24)°, (111.62±8.69)°, (42.06±4.83) mm, (44.21±3.82) mm at 24 months after operation, and the difference were statistically significant (P<0.01). Postoperative Maryland score at 24 months was (93.04±8.83), 40 patients got excellent result, 7 good and 5 fair.
CONCLUSION
Orthopedic manipulation combined with percutaneous reduction and Kirschner wire internal fixation could significantly improve Bühler angle, Gissane angle, width, and height of Sanders typeⅡ and Ⅲ calcaneal fractures, and the curative effect is satisfactory.

OBJECTIVE:
To observe the clinical symptoms and MRI outcomes of patients with ruptured lumbar disc herniation(LDH) through a multicenter randomized controlled study, and to evaluate the clinical efficacy and safety of Yiqi Huoxue formula() in the treatment of this disease.
METHODS:
A total of 160 outpatients and inpatients with ruptured LDH admitted to 4 medical centers from January 2023 to June 2023 were selected and randomly divided into the Yiqi Huoxue formula group and the control group, with 80 patients in each group. In the Yiqi Huoxue formula group, there were 43 males and 37 females, with an age of (41.03±9.56) years and a disease duration of (10.45±25.37) days, and the patients were treated with Yiqi Huoxue formula. In the control group, there were 34 males and 46 females, with an age of (42.14±8.73) years and a disease duration of (11.31±21.14) days;during the acute phase, patients in this group could take celecoxib capsules orally, and methylcobalamin orally at the same time. The Japanese Orthopaedic Association (JOA) score, Oswestry disability index (ODI), changes in the volume of herniated disc tissue on MRI, herniation rate, and absorption rate were recorded at the time of enrollment and during follow-ups at the 3rd, 6th, and 12th month after treatment.
RESULTS:
A total of 156 patients completed the clinical follow-up, and 4 patients withdrew midway. The clinical symptoms of all patients who completed the study were relieved to varying degrees, and reabsorption of herniated disc tissue was observed in all patients in the Yiqi Huoxue formula group after treatment. For the JOA score:in the Yiqi Huoxue formula group, it was (10.73±2.76) points before treatment and (24.65±2.19) points at the 12th month after treatment;in the control group, it was (11.01±1.20) points before treatment and (17.07±3.26) points at the 12th month after treatment. For the ODI score:in the Yiqi Huoxue formula group, it was (26.21±3.55) points before treatment and (5.65±2.19) points at the 12th month after treatment;in the control group, it was (27.92±2.51) points before treatment and (9.09±2.15) points at the 12th month after treatment. At the 12th month after treatment, the JOA and ODI scores of both groups were better than those before treatment, and the scores of the Yiqi Huoxue formula group were better than those of the control group, with statistically significant differences (P<0.05). In terms of the herniated disc volume and herniation rate on MRI, the Yiqi Huoxue formula group was superior to the control group, with statistically significant differences(P<0.05). Reabsorption occurred in 56.96%(45/79) of patients in the Yiqi Huoxue formula group, which was significantly higher than the 37.66%(29/77) in the control group.
CONCLUSION
After treatment with Yiqi Huoxue formula, patients with ruptured LDH show significant improvement in clinical symptoms and a marked reduction in the volume of herniated discs. During the follow-up period, no obvious adverse drug reactions are observed in patients, and no recurrence of symptoms is found at the last follow-up, indicating that the formula has safe and reliable efficacy.

OBJECTIVE:
This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study.
METHODS:
A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants.
RESULTS:
Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m 2) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m 2) and obesity (≥ 28.0 kg/m 2) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m 2 ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses.
CONCLUSION
This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Chronic atrophic gastritis(CAG)is a common intractable gastric disease in clinic,which belongs to the gastric precancerous lesions.Professor LIU Feng-Bin and his team have performed the exploration and practice in the field of CAG for more than 30 years,and they proposed that the evolution of the traditional Chinse medicine(TCM)pathogenesis of inflammation-to-tumor transition(ITT)in CAG was characterized by spleen deficiency being the root cause,qi stagnation,blood stasis and dampness retention being the branch cause,and stasis and toxin being the aggravating factors.Deificiency of the spleen and stomach is the initial factor of CAG,which influences the whole process of the disease.Qi stagnation,blood stasis and dampness retention are the triggering and aggravating factors for the ITT in CAG.The formation of blood stasis and toxin is the key to the progression and transition of CAG.Treatment of ITT in CAG should be based on the results of syndrome differentiation and gastroscopic findings by staging therapy.Before treatment,disease dianosis and syndrome differentiation should be made,and macro and micro syndrome differentiation should be carried out for assistance.Therapy of strengthening the spleen and supporting healthy qi should be implemented throughout the whole process of the disease.The early stage of CAG has the features of gastric mucosa with mild to moderate atrophy and with or without mild intestinal epithelial hyperplasia,the pathogenesis of early CAG is characterized by weakness of the spleen and stomach and is accompanied with the pathological factors of qi stagnation,damp-retention and blood stasis,and the basic treatment should adopt the therapies of strengthening the spleen and clearing heat,regulating qi and activating blood stasis.The advanced stage of CAG has the features of severe atrophic gastric mucosa with or without moderate to severe intestinal epithelial and/or mild to moderate intraepithelial neoplasia,the pathogenesis is characterized by weakness of the spleen and stomach,phlegm blended with blood stasis,and stasis-toxin in the gastric collaterals,and the basic treatment should adopt the therapies of supporting healthy qi and dissipating masses,and unblocking the collaterals and removing toxin,so as to construct an intact line to blocking the ITT in CAG with traditional Chinese medicine.

Objective:To evaluate whether additional radical surgery is necessary following non-curative endoscopic resection of early colorectal cancer.Method:Clinicopathological data in 104 patients following non-curative endoscopic resection of early colorectal coucer at the Department of General Surgery, Peking University First Hospital between Jan 2011 and Dec 2021.Results:Lymph node metastasis and/or residual cancer was found in 23 patients (22%), including 12 cases of lymph node metastasis, 7 cases of residual cancer and 4 patients with both residual cancer and lymph node metastasis. Univariate analysis indicated that vascular infiltration, positive vertical margin, and female gender were risk factors for lymph node metastasis. Risk factors for residual cancer were tumors ≥2 cm in size, negative lift sign, infiltration depth of ≥1 000 μm, and positive horizontal and vertical margins. Multivariate Logistic regression analysis revealed that vascular invasion, positive vertical margins, and being female were independent risk factors for lymph node metastasis, while positive vertical margins was independent risk factor for residual cancer. Salvage surgery lasted for a median of 184 (156-233) minutes, with an estimated blood loss of 50 (20-100) ml and an average postoperative hospital stay of 9 (8-11) days. Seven cases of Clavein-Dindo Ⅱ or higher complications were observed, including pulmonary embolism in 1 case , anastomotic leakage in one, lymphatic fistula in one, bowel obstruction in 2 cases and urinary tract infection in 2 cases.Conclusion:Salvage surgery is mandatory for early endoscopic non-curative resection of colorectal cancer.
