Abstract
Recent advancements in neuroimaging have illustrated that anterior cruciate ligament (ACL) injuries could impact the central nervous system (CNS), causing neuroplastic changes in the brain beyond the traditionally understood biomechanical consequences. While most of previous functional magnetic resonance imaging (fMRI) studies have focused on localized cortical activity changes post-injury, emerging research has suggested disruptions in functional connectivity across the brain. However, these prior investigations, albeit pioneering, have been constrained by two limitations: a reliance on small-sample participant cohorts, often limited to two to three patients, potentially limiting the generalizability of findings, and an adherence to region of interest based analysis, which may overlook broader network interactions. To address these limitations, our study employed resting-state fMRI to assess whole-brain functional connectivity in 15 ACL-injured patients, comparing them to matched controls using two distinct network analysis methods. Using Network-Based Statistics, we identified widespread reductions in connectivity that spanned across multiple brain regions. Further modular connectivity analysis showed significant decreases in inter-modular connectivity between the sensorimotor and cerebellar modules, and intra-modular connectivity within the default-mode network in ACL-injured patients. Our results thus highlight a shift from localized disruptions to network-wide dysfunctions, suggesting that ACL injuries induce widespread CNS changes. This enhanced understanding has the potential to stimulate the development of strategies aiming to restore functional connectivity and improve recovery outcomes.

Abstract
Graft-host mechanical mismatch has been a longstanding issue in clinical applications of synthetic scaffolds for soft tissue regeneration. Although numerous efforts have been devoted to resolve this grand challenge, the regenerative performance of existing synthetic scaffolds remains limited by slow tissue growth (comparing to autograft) and mechanical failures. We demonstrate a class of rationally designed flexible network scaffolds that can precisely replicate nonlinear mechanical responses of soft tissues and enhance tissue regeneration via reduced graft-host mechanical mismatch. Such flexible network scaffold includes a tubular network frame containing inversely engineered curved microstructures to produce desired mechanical properties, with an electrospun ultrathin film wrapped around the network to offer a proper microenvironment for cell growth. Using rat models with sciatic nerve defects or Achilles tendon injuries, our network scaffolds show regenerative performances evidently superior to that of clinically approved electrospun conduit scaffolds and achieve similar outcomes to autologous nerve transplantation in prevention of target organ atrophy and recovery of static sciatic index.

Abstract
Background Despite increased recognition of coexisting tibial and talar osteochondral lesions (OCLs), the risk factors influencing clinical outcomes remain unclear. Purpose To report clinical follow-up results after arthroscopic microfracture surgery in patients with OCLs of the distal tibial plafond and talus and assess possible factors affecting these clinical outcomes. Study Design Case series; Level of evidence, 4. Methods A total of 40 patients with coexisting talar and tibial OCLs who underwent arthroscopic microfracture surgery were included. For analysis, the study used the American Orthopaedic Foot & Ankle Society (AOFAS) scale, Karlsson-Peterson scale, and visual analog scale (VAS) for pain for clinical evaluations on the day before surgery, 12 months after surgery, and at the last follow-up. A stepwise regression model and Spearman rank correlation were used to assess possible factors affecting these clinical outcomes. Results The median follow-up time was 34.5 months (interquartile range [IQR], 26.5-54 months). At the final follow-up, the cohort included 40 patients (26 men and 14 women) with a mean age of 38.8 years (range, 19-60 years). The median AOFAS score increased from 57.5 (IQR, 47-65) before surgery to 88 (IQR, 83-92.5) at the final follow-up, the median Karlsson-Peterson score increased from 48 (IQR, 38.5-67) to 82 (IQR, 76-92), and the median VAS score improved from 5 (IQR, 4-6) to 1 (IQR, 0-2). All scale scores showed significant differences between the preoperative and final follow-up evaluations (P < .001). In the stepwise regression model and Spearman rank correlation analysis, the grade of tibial OCL had a significant independent effect on the final postoperative AOFAS scores of the patients (β = -0.502, P = .001; r = -0.456, P = .003). The size of the tibial lesion also had a significant independent effect on the final postoperative Karlsson-Peterson scores of the patients (β = -0.444, P = .004; r = -0.357, P = .024). Conclusion Arthroscopic microfracture treatment for coexisting talar and tibial OCLs can achieve good short- to midterm clinical outcomes. The grade and size of tibial OCLs are the main risk factors affecting the prognostic functional scores of such patients.

Abstract
Inflammation is part of the natural healing response, but persistent inflammatory events tend to contribute to pathology changes of tendon or ligament. Phenotypic switching of macrophages within the inflammatory niche is crucial for tendon healing. One viable strategy to improve the functional and biomechanical properties of ruptured tendons is to modulate the transition from inflammatory to regenerative signals during tendon regeneration at the site of injury. Here, we developed a tendon repair scaffold made of biodegradable polycaprolactone by electrospinning, which was modified to deliver Wnt3a protein and served as an implant to improve tendon healing in a rat model of Achilles tendon defect. During the in vitro study, Wnt3a protein promoted the polarization of M2 macrophages. In the in vivo experiment, Wnt3a scaffold promoted the early recruitment and counting curve of macrophages and increased the proportion of M2 macrophages. Achilles function index and mechanical properties showed that the implantation effect of the Wnt3a group was better than that of the control group. We believe that this type of scaffold can be used to repair tendon defects. This work highlights the beneficial role of local delivery of biological factors in directing inflammatory responses toward regenerative strategies in tendon healing.

Abstract
Superior mediastinal lymph node metastases in papillary thyroid cancer are uncommon. The clinical characteristics and surgical strategy of superior mediastinal lymph node metastases remain unclear. Superior mediastinal lymphadenectomy can be accomplished either by a transcervical or transsternal approach. Transsternal approach for superior mediastinal lymphadenectomy can cause great damage; transcervical approach sometimes results in inadequate exposure. Here we report our experience of a papillary thyroid cancer patient with superior mediastinal lymph node metastases who underwent video-assisted superior mediastinal lymphadenectomy. A 49-year-old woman diagnosed with papillary thyroid cancer in left thyroid underwent unilateral lobectomy and ipsilateral central and lateral node dissection in the local hospital 4 years ago. Currently lymph node metastases were found in mediastinum and the right neck, some of which were adjacent to the right innominate vein. Unilateral lobectomy, ipsilateral central and lateral node dissection, and video-assisted superior mediastinal lymphadenectomy were successfully performed by transcervical approach. Subsequently, the patient received thyroxine suppression therapy and adjuvant radioiodine treatment. Video-assisted superior mediastinal lymphadenectomy, providing adequate exposure for a complete superior mediastinal lymphadenectomy, is proved to be safe and feasible.

Abstract
Background: There is controversy about whether treatment of chronic lateral ankle
instability (CLAI) with osteochondral lesions of the talus (OLT) can be
performed concurrently. Purpose: To investigate the midterm results of arthroscopic treatment of CLAI combined
with OLT in different surgical settings. It was hypothesized that the
outcomes of treating both injuries at the same time would not be inferior to
those of staged surgery. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: Included were 103 patients with both CLAI and OLT who underwent arthroscopic
microfracture surgery and an open, modified Broström-Gould procedure for
ligament repair from January 2015 to December 2016. The patients were
assigned randomly to a staged group (51 patients) and a single-stage group
(52 patients). The staged group underwent arthroscopic debridement of the
OLT and microfracture, then rehabilitation for 4 to 6 months before
undergoing modified Broström-Gould ligament repair. The single-stage group
underwent both procedures simultaneously. Clinical evaluations were
performed on the day before surgery and at 12-month, 24-month, and final
follow-up periods using the Karlsson-Peterson score, American Orthopaedic
Foot & Ankle Society (AOFAS) score, and pain visual analog scale. The
Karlsson-Peterson score at 24 months postoperatively was considered the
primary outcome. The predefined noninferiority margin for the primary
outcome was −5 points. Results: At the final follow-up, 50 patients in the single-stage group and 48 patients
in the staged group completed the study. The median lesion size was 0.72
cm2 (interquartile range [IQR], 0.5-1.12 cm2) in
the single-stage group and 0.84 cm2 (IQR, 0.7-1.05
cm2) in the staged group. At 12-month follow-up, the single-stage
group had a significantly higher median Karlsson-Peterson score (79 [IQR,
70-85] vs 75 [IQR 65-80] for staged; P = .024) and median
AOFAS score (85 [IQR, 76-89] vs 79.5 [IQR, 70-87] for staged;
P = .045). At 24-month follow-up, the median difference
in the Karlsson-Peterson score for single-stage versus staged surgery was 2
points (95% CI, −2 to 5 points), and the confidence interval was greater
than the predefined value. Conclusion: At midterm follow-up, there was no clinical difference between single-stage
versus staged surgery to treat CLAI with OLT. Single-stage surgery achieved
better clinical outcomes than staged surgery at short-term follow-up.

Abstract
Objective To investigate the effectiveness of partial anterior cruciate ligament (ACL) suture repair with wide awake local anesthesia no tourniquet (WALANT) technique. Methods Between July 2017 and July 2019, 18 patients with partial ACL injury were admitted. There were 10 males and 8 females, with an average age of 40.5 years (range, 22-57 years). There were 5 cases on the left knee and 13 cases on the right knee. Forteen cases had a clear history of trauma or sports injury, and 4 cases had no obvious cause. The time from injury to operation was 1-6 months (median, 3 months). Partial ligament was sutured using WALANT technique under arthroscopy. The operation time, total hospital stay, and postoperative hospital stay were recorded. Lachman test and anterior drawer test were performed to evaluate the knee joint stability after treatment, and Lysholm and International Knee Documentation Committee (IKDC) scores were used to evaluate the knee function. Five-point Likert scaling were used to evaluate postoperative patient satisfaction. Results The operation time was 30-100 minutes (mean, 64.2 minutes). The total hospital stay was 2-12 days (mean, 4.5 days). Postoperative hospital stay was 1-4 days (mean, 1.8 days). All incisions healed by first intention after operation, and no surgery-related complications occurred. All patients were followed up 12-36 months (mean, 19.1 months). Lachman test and anterior drawer test were negative after operation. Lysholm score and IKDC score at 6 and 12 months after operation were significantly higher than those before operation, and at 12 months after operation were higher than those at 6 months after operation, the differences were significant ( P<0.05). At last follow-up, according to five-point Likert scaling of patient satisfaction, 7 cases were very satisfied, 10 cases were relatively satisfied, and 1 case was general. The total patient satisfaction rate was 94.4% (17/18). MRI scan showed the good ligament tension. Conclusion Using WALANT technique to repair partial ACL injuries under arthroscopy can retain the patient's own ligament tissue to the maximum extent and achieve satisfactory short-term effectiveness.

Abstract
Objective To assess the mid-term effectiveness of anterior cruciate ligament (ACL) revision and to analyze the relevant factors that may affect the surgical outcomes. Methods The clinical data of 24 patients who underwent ACL revision surgery between April 2009 and July 2018 and were followed up for more than 2 years were retrospectively analyzed. There were 20 males and 4 females with a median age of 30 years [interquartile distance (IQR) was (25, 36) years]. The median body mass index was 24.45 kg/m 2 and IQR was (22.93, 25.93) kg/m 2. The median time between ACL revision and reconstruction was 41 months and IQR was (15, 85) months. The direct cause of the failure of reconstruction surgery included 14 cases of trauma, 8 cases of no obvious cause, and 2 cases of infection. During the revision operation, 14 patients had a poor bone tunnel position, all of which were drilled with new tunnels, the remaining 10 patients were freshly modified on the basis of the original bone tunnel. Seventeen patients used autogenous tendon revision, 7 patients used LARS ligament; 16 patients had cartilage injury. The Lysholm score, the International Knee Documentation Committee (IKDC) score, and the Tegner sports rating score were used for functional evaluation before operation, at 1 year after operation, and at last follow-up. The Likert satisfaction score was recorded at last follow-up. Results Patients were followed up with a median time of 47 months and IQR was (32, 61) months. The Lysholm score, IKDC score, and Tegner sports rating score were significantly improved at 1 year after operation and at last follow-up when compared with preoperative scores ( P<0.05). There was no significant difference between at last follow-up and at 1 year after operation ( P>0.05). At last follow-up, the median Likert satisfaction score was 4.0 and IQR was (3.0, 4.5). According to the presence or absence of cartilage damage and the type of graft, the above scores at last follow-up were compared between the groups, and the differences were not significant ( P>0.05). At last follow-up, 2 patients had graft fractures due to trauma again, and autogenous iliac bones were taken to fill the bone tunnel, and the second stage was revised; the rest of the patients recovered satisfactorily. Conclusion With preoperative identification of the cause of ACL reconstruction failure, the stability and function of knee joint can be significantly improved by selecting appropriate bone tunnels and grafts during the revision and by active rehabilitation exercises.

Abstract
BACKGROUND As a pattern recognition receptor, Toll-like receptor 7 (TLR7) widely presented in the endosomal membrane of various cells. However, the precise role and mechanism of TLR7 in septic cardiomyopathy remain unknown. This study aims to determine the role of TLR7 in cardiac dysfunction during sepsis and explore the mechanism of TLR7 in septic cardiomyopathy. METHODS We generated a mouse model of septic cardiomyopathy by challenging with lipopolysaccharide (LPS). TLR7-knockout (TLR7-/- ), wild-type (WT) mice, cardiac-specific TLR7-transgenic (cTG-TLR7) overexpression, and littermates WT (LWT) mice were subjected to septic model. Additionally, to verify the role and mechanism of TLR7 in vitro, we transfected neonatal rat ventricular myocytes (NRVMs) with Ad-TLR7 and TLR7 siRNA before LPS administration. The effects of TLR7 were assessed by Ca2+ imaging, western blotting, immunostaining, and quantitative real-time polymerase chain reaction (qPCR). RESULTS We found that TLR7 knockout markedly exacerbated sepsis-induced systolic dysfunction. Moreover, cardiomyocytes isolated from TLR7-/- mice displayed weaker Ca2+ handling than that in WT mice in response to LPS. Conversely, TLR7 overexpression alleviated LPS-induced systolic dysfunction, and loxoribine (TLR7-specific agonist) improved LPS-induced cardiac dysfunction. Mechanistically, these optimized effects were associated with enhanced the adenosine (cAMP)-protein kinase A (PKA) pathway, which upregulated phosphorylate-phospholamban (p-PLN) (Ser16) and promoted sarco/endoplasmic reticulum Ca2+ ATPase (Serca) and Ryanodine Receptor 2 (RyR2) expression in the sarcoplasmic reticulum (SR), and ultimately restored Ca2+ handling in response to sepsis. While improved Ca2+ handling was abrogated after H89 (a specific PKA inhibitor) pretreatment in cardiomyocytes isolated from cTG-TLR7 mice. Consistently, TLR7 overexpression improved LPS-induced Ca2+ -handling decrement in NRVMs. Nevertheless, TLR7 knockdown showed a deteriorative phenotype. CONCLUSIONS Our data demonstrated that activation of TLR7 protected against sepsis-induced cardiac dysfunction through promoting cAMP-PKA-PLN pathway, and we revealed that TLR7 might be a novel therapeutic target to block the septic cardiomyopathy and support systolic function during sepsis.

Abstract
Therapeutic efficacy of P277 against type 1 diabetes was extensively investigated and clinically evidenced. Clinical trials Phases I and II concluded promising results, while the data of P277 immunogenicity in Phase III trials represented weak responses that led to abolish medical use. But, a therapeutic performance of P277 cannot be forgotten. So, in order to exploit its therapeutic benefits and improve its immunogenicity, we developed a new analogue VP to optimize therapeutic efficacy and enhancing immunosuppressive modulations. However, new analogue was purified, and then used to immunize diabetic NOD mice to investigate antidiabetic effects through modulation of immunological status. So, DCs immune responses, relative TLRs, MyD88, and NF-Kβ1 mRNA expression on DCs and splenocytes under VP effect were tested. Circulating and intracellular cytokines were also evaluated at treated and non-treated mice. Splenic T lymphocytes proliferation (Th1 and Treg cells) were also determined. Results revealed that VP significantly down regulates DCs maturation through TLR2, TLR4, and MyD88 pathways. It also shifts DCs to a tolerogenic polarization through NF-Kβ1 pathway that mediates Th1 immunosuppression and enhances iTreg expanding in type1diabetes mice. Meanwhile, we noticed that VP significantly enhances iTreg CD25 + FoxP3+ proliferation. In conclusion, VP showed promising immune potential to modulate immune regulatory responses and shifts DCs to suppress autoreactive Th1 cells which ameliorated immunosuppressive potency in the type1 diabetic mice.

Abstract
WHAT IS KNOWN AND OBJECTIVE Thiopurine methyltransferase (TPMT) enzyme is an important component in the metabolism of azathioprine (AZA). Its mutation may lead to AZA-induced toxicity. The dysfunctional genetic variant TPMT *3C is of low frequency among Asians. Moreover, AZA-induced toxicity still occurs in some patients with normal TPMT activity. This suggests that additional factors, including other genetic variants, may contribute to such toxicity. Recent studies described a strong association between a variant of the NUDT15, a gene that mediates the hydrolysis of some nucleoside diphosphate derivatives, and thiopurine-related myelosuppression in Asians. We report the first case of a Chinese patient with AZA-induced severe toxicity with no clinically significant TPMT variant but with the NUDT15 c.415C>T allele. CASE SUMMARY A 40-year-old Chinese patient with PBC-AIH overlap syndrome had been receiving for one month, azathioprine (50 mg/day) and methylprednisolone (24 mg/day) based on his TPMT*3C wild-type genotype. The patient developed serious myelosuppression and hair loss. AZA was stopped, and the patient was given liver-protective drugs and supportive treatment. TPMT and NUDT15 gene sequencing suggests that NUDT15 c.415C>T mutation was the likely cause of the adverse reaction. WHAT IS NEW AND CONCLUSION NUDT15 c.415C>T may be another predictor of AZA-induced leukocytopenia. If further well-controlled studies validate this association with sufficient predictive power, NUDT15 and TPMT genotyping before starting AZA treatment may become appropriate.

Abstract
A reciprocal translocation between the short arm of chromosome 1 and the long arm of chromosome 3 was observed in a pedigree of three carriers (proband, and his brother and mother). In this study, the three carriers had different clinical manifestations: the proband with infertility, his brother with spousal miscarriages, and his mother with no adverse reproductive history. Cytogenetic analysis of metaphase chromosomes was performed, and triple-color fluorescence in situ hybridization was applied to the detection of aneuploidy sperm related to the interchromosomal effect (ICE). An increase of aneuploidy of chromosome 21 in the proband and aneuploidy of chromosomes 13, 21, and Y in the brother were observed. Since patients with reciprocal translocations and spermatogenetic impairment are candidates, with their partners, for intracytoplasmic sperm injection, the study of the level of sperm aneuploidy rates would provide useful information for couples at risk, as well as contributing to a better understanding of the ICE.

Abstract
PURPOSE Regulatory T cells (Treg) suppress the immune reaction. The aim of the present study was to investigate the clinicopathologic significance and roles of Treg in papillary thyroid carcinoma (PTC) patients with and without Hashimoto's thyroiditis. METHODS Flow cytometry was used to detect the percentage of CD4+CD25+CD127low/- Treg among CD4+ T cells in peripheral blood. FoxP3+ Treg were detected by immunohistochemistry in the tumor tissues. RESULTS The percentage of CD4+CD25+CD127low/- Treg among CD4+ T cells was significantly higher in PTC patients than that in multinodular goiter (MNG) patients. There were large numbers of tumor-infiltrating FoxP3+ Treg in primary PTC and metastatic lymph nodes tissues; however, there was no FoxP3 expression in the MNG tissues. Higher percentage of Treg both in peripheral blood and tumor tissues was associated with extrathyroidal extension and lymph nodes metastasis. The percentage of CD4+CD25+CD127low/- Treg among CD4+ T cells in peripheral blood of PTC patients with Hashimoto's thyroiditis (HT) was significantly lower, whereas the infiltration of FoxP3+ Treg in tissues of PTC with HT tended to be increased. CONCLUSIONS We concluded that the percentage of Treg increased in peripheral blood as well as in the tumor tissues of PTC patients compared with that of MNG patients. The high percentage of Treg was associated with aggressiveness. There may be a compensatory expansion of Treg at the sites of inflammation in tissues of PTC with HT contributing to the immune response suppression.

Abstract
The subsequent reproductive outcomes in couples with a history of recurrent pregnancy loss (RPL) associated with chromosome abnormalities or polymorphisms are generally not reported in China. Many RPL carrier couples have decided not to have children. The present study recorded the subsequent delivery, miscarriage, and unpregnancy outcomes of 113 RPL carrier couples and 226 non-carrier couples, and compared differences in reproductive outcomes between couples with different types of chromosome abnormalities or polymorphisms and chromosome normal couples. Our results showed that couples with RPL associated with parental chromosome abnormalities or polymorphisms did not have significantly lower live birth rates than non-carrier couples in China. These results suggest the current guidance given to Chinese RPL couples.

Abstract
The use of epidural ropivacaine may result in significant haemodynamic fluctuations during combined epidural and general anaesthesia. We designed this study to investigate whether epidural anaesthesia with a goal-directed approach, when combined with general anaesthesia, improved haemodynamic stability in elderly patients undergoing major abdominal surgery. Seventy-five elderly patients undergoing major abdominal surgery were randomly and evenly assigned to one of three groups receiving intraoperative epidural anaesthesia with either ropivacaine 0.1% (Group 1), ropivacaine 0.375% (Group 2) or ropivacaine 0.375% for abdominal wall pain and ropivacaine 0.1% for visceral pain (Group 3). General anaesthesia was induced using a target-controlled infusion of combined propofol and remifentanil. The remifentanil target concentration was adjusted according to the mean arterial pressure and heart rate, and vasoactive agents were administered to maintain stable haemodynamics. The need for vasoactive drug administrations was 1.4 (standard deviation 0.9) in Group 3 (n=24), representing a significantly lower frequency of administration compared with Groups 1 (n=24) and 2 (n=24) (P <0.05 versus Group 1; P <0.01 versus Group 2). The total intraoperative dose of remifentanil was significantly greater in Group 1 (P <0.01 versus Group 2; P <0.05 versus Group 3) but did not differ significantly between Groups 2 and 3. Goal-directed epidural anaesthesia with different ropivacaine concentrations can improve haemodynamic stability when combined with general anaesthesia for elderly patients undergoing major abdominal surgery.

Abstract
OBJECTIVE This study aims to validate a cavity shape optimization approach for improving the debonding resistance of dental restorations by carrying out fracture tests on restored model teeth with standard and optimized cavity designs. METHOD The bio-mimetic stress-induced material transformation (SMT) optimization method was incorporated into the finite element (FE) program ABAQUS as a user material (UMAT) subroutine. The method uses stress minimization to optimize the cavity shape of a MOD restoration in an artificial premolar with special reference to the tooth-restoration interface under occlusal loads. The mechanical performance of the optimized design was first verified through FE analysis and then compared with that of the conventional design using fracture tests on model teeth. RESULTS The SMT optimization process indicated a T-shape cavity as a more favorable design for the MOD restoration in the artificial premolar. Compared with the conventional parallel wall, or undercut design, the T-shape cavity was shown numerically to reduce the interfacial stresses by up to 69%, and experimentally to increase the mean debonding resistance of the model teeth by 23% (p<0.05). SIGNIFICANCE Cavity shape optimization can help increase the debonding resistance of restored teeth by reducing the interfacial stresses between tooth and restoration under occlusal loads.

Abstract
OBJECTIVE To study if the occlusal interference affects the fluctuation of body's gravity center. METHODS An artificial occlusal interference was separately applied on 14 volunteers (7 males and 7 females, mean age 23.2 years). Fluctuations of body's gravity center were measured before wearing the occlusal interference appliance, at 30 minutes and 24 hours after wearing the appliance. RESULTS The length and area of fluctuation of body's gravity center with the interference appliance were greater than that without it. The length of fluctuation of gravity center was 40.22 cm, 41.66 cm and 43.21 cm in eye-opening conditions and 56.96 cm2, 61.93 cm2, 66.9 cm2 in eye-closing condition. The area of fluctuation of gravity center was 3.3 cm2, 3.43 cm2, 3.61 cm2 in eye-opening condition and 4.63 cm2, 5.00 cm2, 6.47 cm2 in eye-closing condition. The female volunteers showed more changes than the male ones. CONCLUSION Occlusal interference does affect the fluctuation of body's gravity center.

Abstract
Western rehabilitation techniques were first introduced into China in the early 1980s. The predominantly 'medical model' of health care in China has resulted in a shortage of rehabilitation personnel and limited experience determining the needs of clients. Occupational therapy practitioners in China are learning their new roles and clients, having never had any contact with occupational therapy, are unaware what services can be offered. The purpose of this research was to determine the most frequently self-identified functional problems (in the ares of self-care productivity and leisure) identified by 113 in-patients in four different hospitals in China, in order to assist therapists to develop programmmes that are responsive to clients' needs. Using the Canadian Occupational Performance Measure, both males and females identified significantly more self-care than leisure or productivity problems (P = 0.01). Females identified more productivity problems than males (P = 0.01) while males appeared to consider leisure difficulties as a priority more frequently than women. The study was jointly undertaken by a Canadian and a Chinese researcher. To our knowledge, this is the first time that occupational therapy personnel in China have formally surveyed clients about their rehabilitation needs, in order to develop priorities for programming.
