Objective To observe the value of immediate CT-guided small negative pressure thoracic drainage for pneumothorax after percutaneous lung biopsy(PTLB).Methods Totally 172 patients of unilateral pneumothorax after PTLB were retrospectively enrolled,including 83 patients underwent immediate CT-guided small negative pressure(about 30 mmHg)thoracic drainage after PTLB(group A)and 89 patients underwent bedside closed thoracic drainage after PTLB(group B).Clinical data before treamtent,degree of pneumothorax,the duration of catheterization,pain degree during catheterization(visual analogue scale[VAS]),blood oxygen saturation after treatment,the ratio of immediate relief of clinical symptoms,duration of drainage retention,duration of hospitalization after treatment and the occurrence of pleural reaction were compared between groups.Results Drainage went smoothly in both groups.No significant difference of clinical data before treatment nor pneumothorax degree was found between groups(all P＞0.05).Compared with those in group B,the duration of catheterization was shorter,and pain degree was lower during drainage in group A(both P＜0.001).After drainage,blood oxygen saturation and the proportion of immediate relief of clinical symptoms in group A were both higher than those in group B,while the duration of drainage retention and hospitalization were both shorter in group A than those in group B(all P＜0.001).Pleural reaction occurred in 2 patients in group A and 1 patient in group B,and no significant difference of pleural reaction was detected between groups(P=0.520).Conclusion Immediate CT-guided small negative pressure thoracic drainage was effective and safe for pneumothorax after PTLB.

Objective:To construct an integrated early rehabilitation program for healthcare and rehabilitation system based on the information-motivation-behavioral skills (IMB) model and evaluate its application effect in patients treated with total hip arthroplasty (THA).Methods:Construction of the rehabilitation program: An integrated research team was established, composed of head burse of orthopedics, orthopedic nursing specialists, orthopedic surgeons, anesthesiologists, and rehabilitation therapists. Considering the key points of perioperative early rehabilitation of THA patients, an integrated early rehabilitation program was constructed based on the IMB model through literature review and expert panel method. Clinical application of the rehabilitation program: A retrospective cohort study was conducted to analyze the clinical data of 100 THA patients admitted to Qingdao Municipal Hospital from March to December 2023, including 47 males and 53 females, aged 60-85 years [(69.8±5.5)years]. Patients were divided into two groups according to their admission time: 50 patients admitted from March to July 2023, receiving routine care (routine care group) and 50 admitted from August to December 2023, receiving intervention through an early rehabilitation program of an integrated healthcare and rehabilitation system based on routine care (integrated care group). The first postoperative ambulation time and length of hospital stay were compared between the two groups. The Harris hip function score was used to assess hip function in both groups at 3 days, 1, 3, and 6 months postoperatively; the Barthel index was used to assess the daily living self-care capacity in both groups preoperatively, at 1, 3, and 6 months postoperatively. The incidence of complications within 6 months after surgery was compared between the two groups.Results:An early integrated rehabilitation program based on the IMB model comprised 25 specific measures of three domains: information support, motivational intervention, and behavioral skills. All the patients were followed up for 6 months. The first postoperative ambulation time and length of hospital stay in the integrated care group were (1.3±0.5)days and (7.4±2.3)days, shorter than (1.5±0.5)days and (8.5±2.3)days in the routine care group ( P<0.05). There were no statistically significant differences in the Harris hip function scores at 3 days postoperatively or preoperative Barthel index between the two groups ( P>0.05). At 1, 3, and 6 months postoperatively, the Harris hip function scores in the integrated care group were (80.3±6.0)points, (88.6±5.2)points, and (92.5±4.1)points, respectively, higher than (75.1±6.3)points, (84.2±5.7)points, and (88.0±5.2)points in the routine care group ( P<0.01); the Barthel index in the integrated care group were (79.2±8.7)points, (87.7±5.7)points, and (92.3±4.9)points, respectively, higher than (72.1±9.0)points, (83.5±6.6)points, and (88.6±5.0)points in the routine care group ( P<0.01). At 6 months postoperatively, the incidence of complications in the integrated care group was 4% (2/50), lower than 16% (8/50) in the routine care group ( P<0.05). Conclusion:Compared with the routine care, an integrated early rehabilitation program for medical care and health based on the information-motivation-behavioral skills model for THA patients can shorten the first postoperative ambulation time and length of hospital stay, restore hip joint function, improve daily living self-care capacity and reduce the incidence of complications.

Objective:To assess the efficacy and safety of azacitidine combined with lenalidomide in MDS patients and explore potential mechanisms of therapeutic response.Methods:Sixteen MDS patients with TP53 mutations received azacitidine plus lenalidomide at ZhongDa Hospital, Southeast University (January 2021–June 2025). Efficacy and safety were assessed, and TP53 mutation status was correlated with treatment response. Whole-transcriptome sequencing and bioinformatics were used to explore molecular biomarkers associated with therapeutic efficacy.Results:Sixteen patients (median age 69.5 years, range 52–82; 8 males, 8 females) were enrolled. According to the Molecular International Prognostic Scoring System (IPSS-M), 1, 2, and 13 patients were classified as median low, high, and very high risk, respectively. Among 16 TP53-mutated patients, 11 had biallelic mutations and 5 had monoallelic mutations. Overall response rate was 56.3% (9/16), composite complete remission rate (CRc) was 31.3% (5/16), and hematology improvement rate was 25% (4/16). Among TP53-mutated patients, the response rate was 56.3% (9/16), with variant allele frequency dropping from 65.6% to 16.5% in responders ( P=0.017). In patients with TP53 mutations and complex karyotype, response rate was 53.8% (7/13), with 57.1% (4/7) showing disappearance of CK post-treatment. The most common grade 3–4 nonhematologic adverse events were infections (9/16, 56.3% ), including pneumonia (4/16, 25.0% ), gastrointestinal infections (3/16, 18.8% ), perianal infections (1/16, 6.3% ) and sepsis (1/16, 6.3% ). High CBX8 expression may be linked to treatment response. Conclusion:Azacitidine plus lenalidomide is an effective and safe therapy for MDS, including patients with TP53 mutations and complex karyotypes. Treatment markedly reduces TP53 variant allele frequency in responders, and high CBX8 expression may predict therapeutic response.

BACKGROUND: As an essential part of health services, rehabilitation is of great significance to improve the health and quality of life of the whole population. Accelerating aging calls for a significant expansion of rehabilitation services in China, but rehabilitation needs remain unclear. We conducted the study to explore the rehabilitation needs in China and project the trend of rehabilitation needs from 2020 to 2034. METHODS: The data of health conditions that might potentially benefit from rehabilitation were obtained from Global Burden of Disease (GBD) study. Estimated annual percentage changes (EAPCs) were calculated to quantify the trends of the age-standardized rates. Projections of rehabilitation needs were made until 2034 using Bayesian age-period-cohort analysis (BAPC). RESULTS: Approximately 460 million persons (33.3% of the total population) need rehabilitation in China, contributing to 63 million years lived with disabilities (YLDs) in 2019. The number of prevalent cases that need rehabilitation increased from around 268 (95% uncertainty interval [UI]: 257-282) million in 1990 to almost 460 (95% UI: 443-479) million in 2019, representing an increase of 71.3%. The highest contribution to the need for rehabilitation was musculoskeletal disorders with about 322 (95% UI: 302-343) million persons in seven aggregate disease and injury categories, and hearing loss with over 95 (95% UI: 84-107) million people among 25 health conditions. Based on the projection results, there will be almost 636 million people (45% of the total population) needing rehabilitation services in China by 2034, representing an increase of 38.3%. The rehabilitation needs of neoplasms, cardiovascular diseases, and neurological disorders are expected to increase significantly from 2019 to 2034, with increases of 102.3%, 88.8% and 73.2%, respectively. CONCLUSIONS The need for rehabilitation in China substantially increased over the last 30 years. It is predicted that over two in five people will require rehabilitation by 2034, thus suggesting the need to develop rehabilitation services that meet individuals' rehabilitation needs.

Objective:To evaluate the clinical efficacy of Jianpi Bushen Prescription in treating acute gouty arthritis with spleen-kidney deficiency syndrome using propensity score matching method.Methods:A retrospective analysis method was used to select 156 patients with acute gouty arthritis with spleen kidney deficiency type admitted from March 2022 to March 2024. They were divided into an observation group of 89 cases and a control group of 67 cases according to the treatment method. Propensity score matching (PSM) was further adopted to balance the confounding factors before treatment in a 1:1 ratio. Finally, 42 patients in each group were successfully matched. The control group received conventional Western medicine, the observation group received additional treatment with Jianpi Bushen Prescription on the basis of the control group. The treatment for both groups lasted for 1 month. TCM syndrome scores were performed before and after treatment, and the levels of serum uric acid (UA), ESR, and pH were measured using an automatic dry biochemical analyzer. The VAS scale was used to assess the degree of pain, the Oswestry Disability Index (ODI) was used to evaluate the degree of joint function improvement, and the Quality of Life Scale-36 (SF-36) was used to evaluate the quality of life of patients. Adverse reactions during treatment were observed and recorded to evaluate clinical efficacy.Results:The total effective rate of the observation group 92.86% (39/42) was higher than that of the control group 73.81% (31/42), with statistical significance ( χ2=5.49, P<0.05). After treatment, the joint pain, soreness and weakness of the waist and knees, poor flexion and extension, and pale and greasy tongue coating, were lower than those in the control group ( t values were 3.38, 4.26, 3.96, 3.97, 4.41, respectively, P<0.01). After treatment, the serum uric acid (UA) [(351.84±36.46) μmol/L vs. (380.19±39.42) μmol/L, t=3.42] and erythrocyte sedimentation rate (ESR) [(17.91±3.71) mm/h vs. (21.43±3.90) mm/h, t=4.24] of the observation group were lower than those in the control group, and the pH value (7.24±0.49 vs. 6.98±0.57, t=2.24) was higher than that of the control group ( P<0.05). After treatment, the VAS and ODI of the observation group were lower than those of the control group ( t values were 5.80, 6.25, respectively, P<0.01), and the SF-36 score was higher than that of the control group ( t=3.23, P<0.05). During the treatment, the incidence of adverse reactions was 14.29% (6/42) in the observation group and 9.52% (4/42) in the control group. There was no statistical significance in the incidence of adverse reactions between the two groups ( χ2=0.45, P>0.05). Conclusions:Jianpi Bushen Prescription has good efficacy on the treatment of acute gouty arthritis with spleen-kidney deficiency syndrome. It can reduce the levels of uric acid, improve the life quality of patients, and enhance efficacy, with good treatment safety.

Objective To explore the effect of continuous cuff compression in improvement of forearm hematoma in patients with percutaneous coronary intervention.Methods A total of 94 patients with coronary intervention for acute myocardial infarction in the hospital from September 2021 to September 2024 were selected as research objects,and they were divided into control group and ob-servation group according to the random number table method,with 47 cases in each group.The control group adopted a customized sphygmomanometer combined with a conventional cuff for intermit-tent compression of the forearm hematoma,and the observation group adopted a customized sphygmo-manometer combined with a double-balloon hollow cuff for continuous compression of the forearm he-matoma.The cyanosis of the hand,wrist skin temperature,numbness and swelling of the hand,the forearm painand heart rate during the cuff compression of the hematoma,as well as the arm circumfer-ence and cuff secondary compression,and direct nursing time of the patients after releasing the cuff compression were compared between the two groups.Results During the period of cuff compression of hematoma,the cyanosis of hand,wrist skin temperature,numbness and swelling of hand,the fore-arm pain and heart rate of the observation group were significantly better than those of the control group(P＜0.05);after releasing the cuff compression,the arm circumference and cuff secondary compression and direct nursing time of the observation group were significantly better than those of the control group(P＜0.05).Conclusion Application of customized sphygmomanometer combined with double-balloon hollow cuff for continuous compression of forearm hematoma can improve patient's comfort degree and cuff compression effect,and reduce nursing workload.

Objective:To summarize the clinical characteristics of children with mitochondrial short-chain enoyl-CoA hydratase-1 deficiency (ECHS1D) caused by c.489G>A (p.Pro163=) compound heterozygous variants in the ECHS1 gene, and to explore genotype-phenotype correlations.Methods:A case series study was performed to analyze clinical, biochemical, metabolic, imaging, genetic, treatment and follow-up outcomes of 24 children with ECHS1 gene c.489G>A(p.Pro163=) variant, who were diagnosed in the Department of Neurology, Beijing Children′s Hospital from July 2010 to June 2024. Disease severity was assessed using the Newcastle Paediatric Mitochondrial Disease Scale, and Fisher exact test was applied to compare the improvement rate between valine-restricted and non-restricted groups.Results:These 24 children were all diagnosed after 2022, with a disease duration of 3.35 (1.25, 6.52) years at diagnosis. A total of 8 children initially had negative genetic results, and were finally confirmed by abnormal splicing of ECHS1 gene via skin fibroblast RNA sequencing, with the longest diagnostic time of 14 years. All 24 children presented with Leigh syndrome, including 11 boys and 13 girls, with an onset age of 1.46 (0.96, 2.79) years; 16 children (67%) were mild cases. Common initial symptoms included developmental delay (9 cases) and paroxysmal dystonia (9 cases), followed by developmental regression (3 cases), nystagmus (2 cases), and epilepsy (1 case). Main manifestations were dystonia (18 cases), developmental regression (14 cases), nystagmus (12 cases), developmental delay (11 cases), ataxia (10 cases), vision loss (9 cases), seizures (2 cases), and hearing impairment (1 case). Among 22 children who underwent blood and urine metabolic screening, 21 children (95%) had elevated urinary 2, 3-dihydroxy-2-methylbutyric acid and 19 children (86%) had elevated urinary S-(2-hydroxypropyl) cysteamine. All 24 children had symmetric abnormal signals in bilateral globus pallidus on cranial magnetic resonance imaging, 10 children had isolated globus pallidus involvement, and other common involved sites included caudate nucleus and brainstem (9 cases each), putamen (7 cases), and cerebral white matter (5 cases). At last follow-up, all 24 children survived, with a follow-up duration of 5.40 (2.75, 8.02) years and a maximum age of 17.8 years; 17 children (71%) had varying degrees of clinical improvement. There was no statistical difference in the improvement rate between children with or without valine-restricted diet (12/14 vs. 5/8, P=0.309). A total of 18 pathogenic variants in the ECHS1 gene were identified among 24 children, 13 of which were distributed in exons 7 and 8; those carrying c.308T>C, c.523G>A, c.796A>G, and c.832G>A variants were mostly severe cases. Conclusions:Children carrying ECHS1 gene c.489G>A(p.Pro163=) compound heterozygous variants face significant diagnostic delay. Clinical awareness of this synonymous variant needs further improvement for timely diagnosis. All these cases present as Leigh syndrome, mostly mild, with no clear genotype-phenotype correlation identified.

Objective:To summarize the long-term efficacy of nicotinamide in treating pediatric early-onset progressive encephalopathy with brain edema and (or) leukoencephalopathy-2 (PEBEL2) caused by NAXD gene variation .Methods:This was a case report conducted from February 2019 to January 2025. The long-term efficacy of nicotinamide was observed by following up a child with PEBEL2 who received the treatment in the Department of Neurology, Beijing Children′s Hospital Affiliated to Capital Medical University. The clinical data included changes in skin lesions, neurological symptoms. The modified Rankin scale (mRS) was used to evaluate the recovery of neurological function.Results:A boy was diagnosed with PEBEL2 caused by NAXD gene variation via genetic testing at Beijing Children′s Hospital Affiliated to Capital Medical University in February 2019, when he was 4 years and 6 months of age. Immediately after diagnosis, nicotinamide treatment was initiated at an initial dose of 100 mg/d, which was increased by 100 mg per week and gradually increased to 500 mg/d; meanwhile, other therapeutic drugs were gradually discontinued. After 1 year and 8 months of treatment, the child′s skin lesions had completely resolved; at the 2-year follow-up, dystonia in both upper limbs and swallowing dysfunction was alleviated significantly; by 2.5-year follow-up, his cognitive function also showed improvement. When the child was treated with 500 mg/d for 3 years, a rash appeared around the mouth. After the dose was reduced to 250 mg/d, the rash resolved, and the dose of 250 mg/d was maintained until the last follow-up. At the last follow-up in January 2025, the child was 10 years and 5 months of age. His mRS score decreased from 5 (before treatment) to 4. During the 6-year of continuous nicotinamide treatment, the child′s condition remained stable without progression. Drug-related skin rashes occurred, but no severe drug-related adverse reactions were observed.Conclusions:PEBEL2 is a treatable mitochondrial disease. Nicotinamide treatment can effectively improve skin lesions and neurological symptoms in PEBEL2 patients, and the long-term administration demonstrates a favorable safety profile.
