OBJECTIVE:
To explore the genetic etiology for a pregnant woman with a history of multiple adverse pregnancies and assess the phenotype-genotype correlation of 22q11.2 microduplication syndrome in her family.
METHODS:
Amniotic fluid sample was taken from a pregnant woman for whom non-invasive prenatal screening indicated chromosome 22 abnormalities in the fetus. Peripheral blood samples from the woman, her brother and parents were collected for high-throughput low-depth whole genome sequencing (CNV-seq). A pedigree traceability analysis of the results was conducted in conjunction with analysis of clinical manifestation. Relevant literature (from establishment to March 2025) was systematically searched. This study was approved by the Medical Ethics Committee of Mianyang Maternal and Child Health Care Hospital (Ethics No.: Lun Shen [2024]009).
RESULTS:
CNV-seq revealed that the fetus had harbored a 6.02 Mb duplication at 22q11.21q11.23. Karyotyping confirmed it as 46,X?dup(22)(q11.2). Pedigree verification demonstrated that the pregnant woman, her brother and mother had all carried the same duplication. Phenotypic analysis of the affected family members showed classic features of 22q11.2 microduplication syndrome, including hypernasal speech, low nasal bridge, congenital heart disease, and cognitive impairment. A total of 44 cases with full information (including three patients from this pedigree) were included in the analysis. The penetrance of 22q11.2 duplication was approximately 29.5% (13/44), and 52.3% (23/44) of the cases had inherited the variant from a phenotypically normal parent.
CONCLUSION
This study has identified the genetic basis for the woman's recurrent adverse pregnancies and phenotypic abnormalities in her family members. The scoliosis identified in her younger brother has not been previously reported, thereby may enrich the clinical phenotype of this syndrome. For fetuses identified with a 22q11.2 microduplication, detailed fetal imaging is recommended, and genetic counseling should be provided to the couples.

Background/Aims:
Data from Asia regarding the short-term and long-term outcomes for acute severe ulcerative colitis (ASUC) are limited. We assessed the outcomes of ASUC, identified the risk factors for colectomy, and compared colectomy rates between the pre-biologics and post-biologics eras in Taiwan.
Methods:
The patients with an ASUC diagnosis between January 2013 and March 2022 at 5 tertiary medical centers were retrospectively analyzed.
Results:
In total, 98 patients were enrolled, with 68.4% diagnosed in the post-biologics era. In 78.6% of the ASUC patients initially received intravenous steroid therapy, for which the success rate was 74.1%. As for rescue therapy, 15 patients (93.8%) received biologics and 1 (6.3%) received cyclosporin. Biologics rescue therapy had a 93.3% success rate. One (1%) mortality due to septic shock occurred. The colectomy rate for index ASUC admission was 11.2%. Patients receiving colectomy were predominantly male (P= 0.012) and at older age (P= 0.016). Higher C-reactive protein (P= 0.035), lower albumin (P= 0.017), and hemoglobin (P= 0.023) levels were associated with colectomy risk. During a median follow-up of 24 months, 13 patients (15.1%) had recurrent ASUC and 23.1% of patients received colectomy. The accumulated colectomy rate at 3 years did not differ between the pre- and post-biologics eras (16.1% vs. 13.4%, P= 0.270).
Conclusions
This is the first Asian study on ASUC to compare colectomy rates between the prebiologics and post-biologics eras, revealing no significant difference. The recurrent ASUC had a higher colectomy rate than the index ASUC.

This paper summarizes the clinical experience of professor ZHANG Zhiwen in differentiating and treating chronic obstructive pulmonary disease (COPD) at stages, with the method of diffusing and clearing to unblock the channel pathways, while warming and subduing to restore the original qi. Professor ZHANG posits that the core pathogenesis of this disease lies in depletion of original qi, leading to impaired qi transformation of sanjiao (三焦), and obstruction of channel pathways. Accordingly, a staged differentiation and treatment strategy based on the methods of diffusing and clearing to unblock the channel pathways, while warming and subduing to restore the original qi has been proposed. COPD was divided into the acute exacerbation stage and the stable stage. In acute exacerbation stage, priority is given to diffusing lung and clearing up turbidity, scatter and dredge the channel passages, using the self-formulated Xuandi Tongsui Formula (宣涤通隧方). During the stable stage, the treatment should focus on simultaneously regulating sanjiao, warming and subduing yang to restore the original qi, using the self-formulated Wenqian Guiyuan Formula (温潜归元方). In addition, the principles of carefully protecting mild yang, avoiding excessive astringent medicinals, and restoring respiration to its root are emphasized throughout the entire course of disease prevention, treatment, and rehabilitation.

ObjectiveTo evaluate the safety and efficacy of oxycodone versus sufentanil for postoperative analgesia in patients with moderate to severe obstructive sleep apnea (OSA) undergoing uvulopalatopharyngoplasty (UPPP). MethodsWe enrolled 73 consecutive patients with moderate-to-severe OSA (confirmed by polysomnography) scheduled for elective UPPP under general anesthesia at our institution between August 2023 and August 2025. Patients were randomly assigned to receive oxycodone (n = 37) or sufentanil (n = 36) using a random number table . The sufentanil group received 1.5 μg per kilogram of body weight, and the oxycodone group received 0.9 mg per kilogram; both groups used patient-controlled intravenous analgesia (PCIA) pumps with a total volume of 100 mL. A 2 mL loading dose was administered 10 minutes before the end of surgery, followed by a background infusion of 2 mL per hour, 2 mL bolus doses on demand, an 8-minute lockout interval, and a maximum hourly volume of 10 mL. We assessed pain scores (Numerical Rating Scale) at rest and during swallowing, Ramsay sedation scores, morphine-equivalent opioid consumption, PCIA bolus demands, patient satisfaction, time to first oral intake, and adverse events (including respiratory depression, nausea, and vomiting) at 4, 12, 24, and 48 hours postoperatively. ResultsBaseline characteristics were well balanced between the two groups (all P>0.05). No significant between-group differences were observed in resting and swallowing NRS scores or Ramsay sedation scores at each postoperative time point, PCIA satisfaction, time to first oral intake, or adverse event incidence across all postoperative time points (all P>0.05). Morphine-equivalent opioid consumption was significantly lower in the oxycodone group at all time points, as were unsuccessful PCIA bolus demands at 24 and 48 hours postoperatively (both P<0.05). ConclusionsLow-dose oxycodone provided analgesic efficacy similar to that of sufentanil for PCIA after UPPP in patients with moderate-to-severe OSA, with no significant between-group differences in adverse events, time to first oral intake, or satisfaction .The oxycodone group had numerically lower adverse event rates and a shorter time to first oral intake, suggesting a favorable safety profile and potential benefits for reducing opioid-related events and facilitating earlier recovery in this patient population.

ObjectiveIn the realm of forensic science, dust is a valuable type of trace evidence with immense potential for intricate investigations. With the development of DNA sequencing technologies, there is a heightened interest among researchers in unraveling the complex tapestry of microbial communities found within dust samples. Furthermore, striking disparities in the microbial community composition have been noted among dust samples from diverse geographical regions, heralding new possibilities for geographical inference based on microbial DNA analysis. The pivotal role of microbial community data from dust in geographical inference is significant, underscoring its critical importance within the field of forensic science. This study aims to delve deeply into the nuances of fungal community composition across the urban landscapes of Beijing, Fuzhou, Kunming, and Urumqi in China. It evaluates the accuracy of biogeographic inference facilitated by the internal transcribed spacer 2 (ITS2) fungal sequencing while concurrently laying a robust foundation for the operational integration of environmental DNA into geographical inference mechanisms. MethodsITS2 region of the fungal genomes was amplified using universal primers known as 5.8S-Fun/ITS4-Fun, and the resulting DNA fragments were sequenced on the Illumina MiSeq FGx platform. Non-metric multidimensional scaling analysis (NMDS) was employed to visually represent the differences between samples, while analysis of similarities (ANOSIM) and permutational multivariate analysis of variance (PERMANOVA) were utilized to statistically evaluate the dissimilarities in community composition across samples. Furthermore, using Linear Discriminant Analysis Effect Size (LEfSe) analysis to identify and filter out species that exhibit significant differences between various cities. In addition, we leveraged SourceTracker to predict the geographic origins of the dust samples. ResultsAmong the four cities of Beijing, Fuzhou, Kunming and Urumqi, Beijing has the highest species richness. The results of species annotation showed that there were significant differences in the species composition and relative abundance of fungal communities in the four cities. NMDS analysis revealed distinct clustering patterns of samples based on their biogeographic origins in multidimensional space. Samples from the same city exhibited clear clustering, while samples from different cities showed separation along the first axis. The results from ANOSIM and PERMANOVA confirmed the significant differences in fungal community composition between the four cities, with the most pronounced distinctions observed between Fuzhou and Urumqi. Notably, the biogeographic origins of all known dust samples were successfully predicted. ConclusionSignificant differences are observed in the fungal species composition and relative abundance among the cities of Beijing, Fuzhou, Kunming, and Urumqi. Employing fungal ITS2 sequencing on dust samples from these urban areas enables accurate inference of biogeographical locations. The high feasibility of utilizing fungal community data in dust for biogeographical inferences holds particular promise in the field of forensic science.

Objective To evaluate the occupational health literacy (OHL) level and its influencing factors among individuals of six key industries from Jiulongpo District, Chongqing City. Methods A total of 2 022 frontline workers from six key industries in the Jiulongpo District of Chongqing City were selected as the research subjects using a cluster sampling method. The OHL level of the workers were assessed using the Occupational Health Literacy Questionnaire of National Key Populations. Results The overall OHL level among the 2 022 frontline workers was 51.43%. The OHL level in the four dimensions of basic knowledge of occupational health protection, healthy work practices and behaviors, legal knowledge of occupational health, and basic skills of occupational health protection were 81.45%, 56.08%, 43.42%, and 37.59%, respectively. The OHL levels of the six key industries from high to low were electrical machinery and equipment manufacturing, healthcare, education, express delivery/food delivery, transportation, and environmental hygiene, accounted for 91.43%, 61.98%, 52.64%, 40.58%, 36.70% and 31.15% (P<0.01). The results of logistic regression analysis showed that population of Han had higher OHL level than ethnic minorities (P<0.01), married individuals had lower OHL level than unmarried individuals (P<0.05), individuals with college education or above had higher OHL level than those with junior high school education or below (P<0.01), and higher personal monthly income was associated with higher OHL levels (all P<0.05). The OHL levels of workers of environmental hygiene, transportation, education, express delivery/food delivery, and healthcare were lower than those in electrical machinery and equipment manufacturing (all P<0.01). Conclusion The OHL level among occupational populations in the six key industries in Jiulongpo District, Chongqing City, needs to be further improved. And the OHL monitoring and intervention should be focused on the occupational population of express delivery/food delivery industry, transportation, environmental hygiene, and occupational population with low income, low educated, and ethnic minorities.

ObjectiveTo observe the clinical efficacy and safety of Tangning Tongluo tablets in the treatment of nonproliferative diabetic retinopathy (DR). MethodsFourteen research centers participated in this study, which spanned a time interval from September 2021 to May 2023. A total of 240 patients with nonproliferative DR were included and randomly assigned into an observation group (120 cases) and a control group (120 cases). The observation group was treated with Tangning Tongluo tablets, and the control group with calcium dobesilate capsules. Both groups were treated for 24 consecutive weeks. The vision, DR progression rate, retinal microhemangioma, hemorrhage area, exudation area, glycosylated hemoglobin (HbA1c) level, and TCM syndrome score were assessed before and after treatment, and the safety was observed. ResultsThe vision changed in both groups after treatment (P<0.05), and the observation group showed higher best corrected visual acuity (BCVA) than the control group (P<0.05). The DR progression was slow with similar rates in the two groups. The fundus hemorrhage area and exudation area did not change significantly after treatment in both groups, while the observation group outperformed the control group in reducing the fundus hemorrhage area and exudation area. There was no significant difference in the number of microhemangiomas between the two groups before treatment. After treatment, the number of microhemangiomas decreased in both the observation group (Z=-1.437, P<0.05) and the control group (Z=-2.238, P<0.05), and it showed no significant difference between the two groups. As the treatment time prolonged, the number of microhemangiomas gradually decreased in both groups. There was no significant difference in the HbA1c level between the two groups before treatment. After treatment, the decline in the HbA1c level showed no significant difference between the two groups. The TCM syndrome score did not have a statistically significant difference between the two groups before treatment. After treatment, neither the TCM syndrome score nor the response rate had significant difference between the two groups. With the extension of the treatment time, both groups showed amelioration of TCM syndrome compared with the baseline. ConclusionTangning Tongluo tablets are safe and effective in the treatment of nonproliferative DR, being capable of improving vision and reducing hemorrhage and exudation in the fundus.

Objective:To compare the clinical efficacy of robot-assisted balloon tibioplasty and traditional open reduction and internal fixation in the treatment of AO/OTA type 41B2 tibial plateau fracture.Methods:A retrospective cohort study was conducted to analyze the clinical data of 70 patients with AO/OTA type 41B2 tibial plateau fracture who were admitted to Wuhan Fourth Hospital from September 2019 to October 2022, including 35 males and 35 females, aged 24-62 years [(44.9±9.5)years]. Among them, 41 patients underwent traditional open reduction and internal fixation (open reduction group), while 29 patients underwent robot-assisted balloon tibioplasty (balloon group). The following parameters were compared between the two groups: incision length, operative blood loss, number of intraoperative fluoroscopies, operation duration, and length of hospital stay; Rasmussen radiological scores at 3 days, 3 months postoperatively, and at the last follow-up and the fracture healing time; pain visual analogue scale (VAS) scores preoperatively, and at 2 days and 3 months postoperatively; knee joint range of motion at 5 days, 3 months postoperatively, and at the last follow-up; Hospital for Special Surgery (HSS) knee function scores at 3, 6 months postoperatively, and at the last follow-up; incidence rate of complications at 15 days postoperatively.Results:All the patients were followed for 12-24 months [18(17, 20)months]. The incision length, operative blood loss and length of hospital stay in the balloon group were 1.6(1.5, 3.0)cm, 5.0(5.0, 5.0)ml and 11.0(9.0, 14.0)days, less than those in the open reduction group [12.0(11.0, 12.0)cm, 100.0(50.0, 120.0)ml and 15.0(13.0, 20.0)days] ( P<0.01). The number of intraoperative fluoroscopies and operation duration in the open reduction group were 9.0(7.0, 10.0)times and 75.0(60.0, 90.0)minutes, less than those in the balloon group [336.0(335.0, 340.0)times and [90.0(70.0, 105.0)minutes] ( P<0.05). There were no significant differences in the Rasmussen radiological scores between the two groups at 3 days, 3 months postoperatively, or at the last follow-up ( P>0.05). The fracture healing time in the balloon group was 3.0(3.0, 3.0)months, shorter than 3.0(3.0, 3.5)months in the open reduction group ( P<0.05). No significant differences were observed between the two groups in VAS scores before operation or at 3 months postoperatively ( P>0.05). However, the VAS score was 2.0(2.0, 3.0)points at 2 days postoperatively in the balloon group, lower than 5.0(5.0, 6.0)points in the open reduction group ( P<0.01). The knee joint range of motion at 5 days, 3 months postoperatively and at the last follow-up were 90.0(85.0, 90.0)°, 135.0(130.0, 135.0)° and 140.0(135.0, 140.0)° in the balloon group, better than 65.0(60.0, 70.0)°, 125.0(120.0, 130.0)°, 130.0(130.0, 140.0)° in the open reduction group ( P<0.01). Similarly, the HSS knee function scores at 3, 6 months postoperatively and at the last follow-up were 80.0(80.0, 81.0)points, 91.0(90.0, 92.0)points, and 95.0(93.0, 96.0)points in the balloon group, better than 71.0(70.0, 72.0)points, 83.0(81.0, 84.0)points, and 86.0(84.0, 88.0)points in the open reduction group ( P<0.01). The incidence rate of complications in the balloon group was 0, comparable to 12% (5/41) in the open reduction group ( P>0.05). Conclusion:Compared with traditional open reduction and internal fixation surgery, robot-assisted balloon tibioplasty in the treatment of AO/OTA type 41B2 tibial plateau fracture significantly reduces surgical trauma, alleviates postoperative pain, promotes fracture healing, and accelerates functional recovery of the affected limbs.

OBJECTIVES:
To investigate the changes in blood levels of calcium and bone metabolism biochemical markers in patients with primary osteoporosis receiving treatment with denosumab.
METHODS:
Seventy-three patients with primary osteoporosis treated in our Department between December, 2021 and December 2023 were enrolled. All the patients were treated with calcium supplements, vitamin D and calcitriol in addition to regular denosumab treatment every 6 months. Blood calcium, parathyroid hormone (PTH), osteocalcin (OC), type I procollagen amino-terminal propeptide (PINP), and type I collagen carboxy-terminal telopeptide β special sequence (β‑CTX) data before and at 3, 6, 9, and 12 months after the first treatment were collected from each patient.
RESULTS:
Three months after the first denosumab treatment, the bone turnover markers (BTMs) OC, PINP, and β-CTX were significantly decreased compared to their baseline levels by 39.5% (P<0.001), 56.2% (P<0.001), and 81.8% (P<0.001), respectively. At 6, 9, and 12 months of treatment, OC, PINP, and β-CTX remained significantly lower than their baseline levels (P<0.001). Blood calcium level was decreased (P<0.05) and PTH level increased (P<0.05) significantly in these patients at months of denosumab treatment, but their levels were comparable to the baseline levels at 6, 9, and 12 months of the treatment (P>0.05).
CONCLUSIONS
Denosumab can suppress BTMs and has a good therapeutic effect in patients with primary osteoporosis, but reduction of blood calcium and elevation of PTH levels can occur during the first 3 months in spite of calcium supplementation. Blood calcium and PTH levels can recover the baseline levels as the treatment extended, suggesting the importance of monitoring blood calcium and PTH levels during denosumab treatment.
