Organoid technology， a rapidly advancing three-dimensional （3D） cell culture platform， can closely mimic the microarchitecture and functions of human digestive organs， effectively overcoming the limitations of conventional two-dimensional cell models and animal experiments. By systematically summarizing the distinctive strengths of organoid technology in simulating digestive physiological and pathological states， constructing digestive system disease models， enabling high-throughput drug screening， and facilitating personalized treatment， this review explored the potential applications of organoids in identifying active components of traditional Chinese medicine （TCM） formulas， evaluating in vitro pharmacokinetics and toxicological parameters， and investigating multi-target synergistic mechanisms. By integrating cutting-edge engineering technologies， organoids are expected to provide a more scientific research platform for TCM， accelerate the modernization of its mechanistic studies， and enhance its scientific value and global impact.

Objective:To explore the clinical efficacy and safety of daratumumab-based combined regimens for relapsed/refractory multiple myeloma (RRMM).Methods:A retrospective case series study was conducted. The clinical data of 38 patients with RRMM in Jining NO.1 People's Hospital from Janunary 2020 to December 2022 were retrospectively analyzed. All patients were treated with daratumumab-based combined regimens. The Dd regimen (12 cases) was treated with daratumumab and dexamethasone, the DPD regimen (20 cases) was treated with pomalodomide based on the Dd regimen, the DVD regimen (6 cases) was treated with bortezomib based on the Dd regimen. The therapeutic efficacy and adverse reactions of all groups were analyzed. Kaplan-Meier method was used for survival analysis.Results:The median follow-up time was 9.5 months (1.0 months, 32.5 months) and the median treatmemt time was 6.2 months (3.2 months, 25.6 months). Among 38 patients, 7 cases (18.7%) achieved complete remission, 9 cases (23.6%) achieved very good partial remission, 10 cases (26.3%) achieved partial remission, 4 cases (10.5%) achieved minimal remission, 5 cases (13.1%) achieved stable disease, 3 cases (7.9%) had the progression of the disease. The overall response rate (ORR) was 78.9% (30/38). The ORR was 66.7%(8/12), 83.3%(5/6), 85.0%(17/20), respectively in the Dd group, DVD group and DPD group. There was no statistically significant difference in the ORR between the DVD group and DPD group ( χ2 = 0.01, P>0.05); there was no statistically significant difference in the ORR between the DVD group and Dd group ( χ2 = 0.55, P>0.05); there was no statistically significant difference in the ORR between the DPD group and Dd group ( χ2 = 1.47, P>0.05). The median progression-free survival (PFS) time was 12.5 months (95% CI: 8.5-24.2 months),the median overall survival (OS) time was not reached, and the 1-year OS rate was 89.4%. Among 38 patients, the main adverse reactions during treatment were infusion-related adverse reactions in 5 cases, grade 3 neutropenia in 7 cases, grade 3 thrombocytopenia in 9 cases, severe anemia in 12 cases; no one had drug discontinuation or drug reduction due to the intolerance of adverse reactions. Conclusions:Daratumumab-based combined regimens in the treatment of RRMM show a favorable efficacy and safety.

Objective:To explore the clinical effect and safety of venetoclax combined with azacitidine for high-risk myelodysplastic syndromes (MDS).Methods:A retrospective case series study was conducted. The clinical data of 48 patients with high-risk MDS in Jining No.1 People's Hospital from January 2020 to May 2023 were collected, and all patients were divided into the control group (20 cases) and the test group (28 cases) according to medications. The control group was treated with azacitidine alone, and the test group was treated with venetoclax combined with azacitidine regimen. The total effective rate and adverse reactions of the 2 groups were compared after 3 courses of treatment.Results:Among 48 patients, 30 cases were male and 18 cases were females; the median onset age [ M ( Q1, Q3)] was 62 years (54 years, 75 years). There were no statistically significant differences in gender, age, white blood cell count, neutrophil count, hemoglobin, platelet count, bone marrow original cells proportion between the 2 groups (all P>0.05). After 3 courses of treatment, the total effective rate in the test group was 75% (22/28), and the rate in the control group was 45% (9/20), and there was a statistically significant difference between the two groups ( χ2 = 5.74, P<0.05). The incidence of grade 3 and the above adverse reactions in the control group and the test group was 25% (5/20), 54% (15/28), respectively, and the difference was statistically significant ( χ2 = 1.62, P>0.05). Conclusions:Venetoclax combined with azacitidine regimen for high-risk MDS can improve the clinical efficacy, and the adverse reactions can be tolerated.

Objective:To explore the morphological characteristics of the pectoralis major muscle and the anatomical relationship of adjacent structures .Methods:A total of 156 patients undergoing thyroid surgery at the First Hospital of Anhui University of Science & Technology and the First Affiliated Hospital of University of Science and Technology of China from Dec 2020 to Sep 2022 were includeed. Those adopting routine endoscopic thyroidectomy by gasless unilateral axillary approach were assigned to group A,and searching for the sternocleidomastoid muscle through the pectoralis major muscle gap on this basis to group B.Results:Among the 78 patients in group B, a total of 71 (91%) cases were found to have a typical sternocleidomastoid muscle gap, and in 7 (9%) cases were not found. The morphology phenotypes of the gap between the clavicular part and thoracic ribs part of the pectoralis major muscle was found in 3 types: obvious separation type (typeⅠ), inconspicuous separation-partially overlapped type (typeⅡa), and inconspicuous separation-completely anastomosed type (type Ⅱb). The mean duration of surgery in group B was less (105±15) min than that in group A (156±27) min ( t=14.523, P<0.01); postoperative one day drainage in group B was less (49±6) ml than that in group A (51±6) ml ( t=2.273, P=0.024). There was no statistically significant difference in intraoperative bleeding, postoperative hospital stay and complication rate between the two groups ( t=0.557, P=0.578; t=0.134, P=0.894; χ2=1.844, P=0.174). Conclusion:The search for the sternocleidomastoid muscle through the pectoralis major muscle gap in the endoscopic thyroidectomy by gasless unilateral axillary approach can shorten the duration of surgery and improve the efficiency of surgery.

Objective:To investigate the surgical treatment efficacy and experience of invasive thalamus cavernous malformations (CMs).Methods:A retrospective analysis was performed. The clinical and follow-up data of 8 patients with invasive thalamus CMs, admitted to our hospital from July 2007 to June 2020, were chosen. These patients accepted minimally invasive resection via sylvian fissure-insular approach after the second rapture hemorrhage; follow up was performed for 8 months-10 years. Results:The lesions of these 8 patients were near the lateral thalamus, and the lesions were completely removed during the surgery. Within 24 h of surgery, the lower limb muscle strength of one patient was improved to grading 2, and that of 2 patients was improved to grading 1. Follow up results 6 months after treatment showed that the modified Rankin scale scores were 1-3 in 5 patients and 4 in 3 patients; and there were no recurrence during the follow-up of (49.7±37.8) months.Conclusion:The resection via sylvian fissure-insular approach is safe and effective for patients with invasive thalamus CMs after the second rapture hemorrhage.

Objective:To estimate the incidence and mortality of corpus uteri cancer in China, 2015.Methods:Quality audit and evaluation of the data from 2015 cancer registration reported by 501 cancer registries were conducted, and 368 cancer registries were included in the analysis. The incidence rate and mortality rate of corpus uteri cancer were calculated according to the factors of the region (urban, rural, east, central, western), sex and age groups. The incidence and mortality of corpus uteri cancer with the 2015 population were estimated. Chinese standard population in 2000 and world Segi′s population were used for the calculation of age-standardized rates (ASR) of incidence and mortality.Results:In 2015, 368 cancer registries included in the analysis covered a total of 309 553 499 populations in China, accounting for 22.52% of the national population. It is estimated that there were about 68 900 new cases of corpus uteri cancer in 2015, the incidence rate was 10.28/10 5, age-standardized incidence rates by Chinese standard population (ASR China) and world standard population (ASR world) were 6.86/10 5 and 6.66/10 5, respectively. The incidence rate of urban area (11.35/10 5) was higher than that of rural area (8.90/10 5), and the incidence of eastern region (12.12/10 5) was higher than the central region (9.94/10 5) and the western region (8.25/10 5). It is estimated that in 2015, there were about 16 000 deaths of corpus uteri cancer, the mortality rate was 2.39/10 5, ASR China was 1.49/10 5, ASR world was 1.47/10 5. The mortality in urban areas (2.40/10 5) is close to rural areas (2.39/10 5); the mortality in central areas (2.55/10 5) was higher than the eastern areas (2.32/10 5) and the western areas (2.31/10 5). Conclusions:In China, the incidence of corpus uteri cancer is on the rise and has a trend of youth, the burden of disease is gradually increasing, which threatens the health of women. Targeted prevention and control measures should be carried out in the different regions.

Objective To compare the surgical effects between minimally invasive anterior ondontoid screw fixation assisted by our self-designed odontoid guider and open anterior ondontoid screw fixation in the treatment of odontoid fractures of Anderson-D'Alonzo type Ⅱ.Methods From July 2011 to July 2016,28 adults with odontoid fracture of Anderson-D'Alonzo type Ⅱ were treated at Department Ⅱ of Spinal Surgery,Hospital of 89 Army Group of Chinese PLA.Of them,15 were treated by minimally invasive anterior ondontoid screw fixation assisted by our self-designed odontoid guider (guider group) while the other 13 by open anterior ondontoid screw fixation (open group).All the patients were male,aged from 31 to 59 years (average,42.7 years).The 2 groups were compared in terms of incision length,operation time,intraoperative bleeding,intraoperative fluoroscopic frequency and hospital stay.Results There were no significant differences between the 2 groups of patients in their preoperative general data,indicating they were compatible (P ＞ 0.05).All the patients were followed up for 12 to 45 months (average,22.1 months).The internal fixation was in good place and clinical union achieved in all the 28 patients.The incision length (2.2 ± 0.1 cm),operation time (45.0 ± 3.1 min),intraoperative bleeding (29.0 ± 2.3 mL) and intraoperative fluoroscopic frequency (15.5 ± 1.9 times) for the guider group were all significantly less than those (2.9 ±0.7 cm,61.6±3.8 min,51.6±3.9 mL and 21.7±3.2 times,respectively) for the open group (P ＜0.05),but there was no significant difference between the 2 groups in hospital stay (6.5 ± 0.5 d versus 6.5 ± 0.6 d) (P ＞ 0.05).Conclusion In the treatment of odontoid fractures of Anderson-D'Alonzo type Ⅱ,compared with open anterior ondontoid screw fixation,the minimally invasive anterior ondontoid screw fixation assisted by our self-designed odontoid guider may lead to a smaller incision,shorter operation time,less blood loss and a lower fluoroscopic frequency.

Objective To explore a simple classification of the axial mastoid process and its clinical significance in improving the traditional screw insertion in the treatment of odontoid fracture with percutaneous anterior odontoid screwing. Methods The median sagittal CT images of 120 patients with cervical dis-ease were measured. They were 63 males and 57 females, aged from 31 to 59 years (average, 41.6 years). On their median sagittal CT images, line A was the connection of the lowest point of the anterior inferior boarder of the axis body to the vertex of the odontoid process and line B a parallel line to line A through the mastoid process. The distance between lines A and B was measured (the height of the axial mastoid process) and a complete statistical record was made to analyze the distribution and regularity of distances AB. The improved insertion points were indentified based on the above measurements (X25%and X75%) and clinical ex-perience. We reviewed 32 patients with odontoid fracture of Anderson&D' Alonzo typeⅡA, ⅡB or superficialⅢ. Of them 15 underwent percutaneous anterior screwing by the improved insertion points and 17 underwent percutaneous anterior screwing by the conventional insertion points. The 2 groups were compared in terms of incision length, operation time, bleeding, fluoroscopy frequency and hospital stay. Results Distance AB was 3.42 ± 0.68 mm. The distance AB <3 mm was classified as low-level mastoid process, the distance AB between 3 to 4 mm as slightly convex mastoid process, and the distance AB > 4 mm as convex mastoid process. Of the 120 patients, 32 (26.7% ) were classified as having a low-level mastoid process, 57 (47.5%) as having a slightly convex mastoid process, and 31 (25.8%) as having a convex mastoid process. Compared with the conventional insertion group, the improved insertion group had significantly shorter oper-ation time (31.32 ± 2.12 min versus 46.18 ± 3.63 min), significantly lower fluoroscopy frequency (18.20 ±1.57 times versus 21.27 ± 2.50 times) but significantly greater bleeding (43.22 ± 3.17 mL versus 31.22 ± 3.52 mL) (P <0.05). There were no significant differences between the 2 groups in incision length or hospital stay (P > 0.05). Conclusions In the treatment of odontoid fracture with percutaneous anterior odontoid screwing, the screw insertion can be improved according to our classification of the axial mastoid process. Our simple classification of the axial mastoid process may lead to more efficient operation and less radiation hazard.

OBJECTIVE: To explore the method of the controlled synechiae technique to maintain the stability of middle turbinate (MT), reduce the incidence of middle meatus synechia formation and improve the treatment effect of endoscopy surgery. METHOD: Eighty-six patients with chronic sinusitis were randomly divided into control group and treatment group in this study. In control group, the patients received extended nasal packing in middle meatus until 1 week after surgery. In treatment group, the patients received the controlled synechiae technique. RESULT: The MT position was described as stable, slight drifting laterally and synechia formation. And the incidence of synechia between MT and the nasal lateral wall was 29.4% and 14.9% in control group and treatment group,respectively. The differences were significant (P < 0.05). CONCLUSION For those patients with anatomic variation, destruction or weak supporting structures resulted from previous surgery, the controlled synechiae technique is very useful in preventing lateralization of the middle turbinate after endoscopy surgery.
