BackgroundSchizophrenia patients are often accompanied by negative symptoms and severe cognitive impairment, but effective interventions intended to alleviate such condition are currently limited. Existing researches on group play therapy for schizophrenia is still in its initial stages, and such therapy has the potential to contribute to symptoms improvement. ObjectiveTo explore the efficacy of group play therapy on improving cognitive function and negative symptoms in hospitalized female patients with schizophrenia, so as to provide references for clinical intervention in such group. MethodsThis study involved 40 female patients with schizophrenia who received inpatient treatment at the Third People's Hospital of Fuyang from April 2022 to May 2023 as well as met the diagnostic criteria of the International Classification of Diseases, tenth edition (ICD-10). They were divided into study group (n=20) and control group (n=20) according to the random number table method. Both groups received routine treatment, and the study group received 10 sessions of group play therapy for 5 weeks on the basis. At baseline, Scale for Assessment of Positive Symptoms (SAPS), Scale for Assessment of Negative Symptoms (SANS), Self-rating Depression Scale (SDS), Nurses' Observation Scale for Inpatient Evaluation (NOSIE), and Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) were used for assessment. Post-therapy evaluation was conducted by using SAPS, SANS and RBANS. Patients' baseline SAPS scores, SANS scores, RBANS total scores, and various factor scores of RBANS were used as covariates, and covariance analysis was adopted to compare the scores of each scale between the two groups after treatment. ResultsA total of 39 patients went through the whole study. Results of covariance analysis showed that the SANS score of study group was lower than that of control group, while several scores of RBANS (including total score, immediate memory factor score, speech function factor score and attention factor score) were all higher than those in control group. Significant difference was observed between two groups in scores of both scales above (F=13.408, 10.331, 4.932, 9.967, 10.010, P<0.05 or 0.01). ConclusionGroup play therapy may help improve negative symptoms and cognitive function in hospitalized female patients with schizophrenia.

Objective: To investigate the clinical effects of en bloc resection and debridement combined with gluteus maximus muscle flap in the treatment of ischial tubercle pressure ulcer complicated with chronic osteomyelitis. Methods: A retrospective observational study was conducted. From May 2018 to February 2020, 8 patients with pressure ulcers on the ischial tuberosity combined with chronic osteomyelitis who met the inclusion criteria were admitted to Fuyang Minsheng Hospital, including 5 males and 3 females, aged 38-69 years, with unilateral lesions in 6 patients and bilateral lesions in 2 patients. According to the anatomical classification of Cierny-Mader osteomyelitis, there were 6 patients (7 sides) with focal type, and 2 patients (3 sides) with diffuse type. The wound areas were 3 cm×2 cm to 12 cm×9 cm on admission. The pressure ulcer and chronic osteomyelitis lesions were completely removed by en bloc resection and debridement. The chronic infectious lesions were transformed into sterile incisions like fresh wounds by one surgical procedure, and the gluteus maximus muscle flaps with areas of 10 cm×6 cm to 15 cm×9 cm were excised to transfer and fill the ineffective cavity. The wounds of 5 patients were sutured directly, and the wounds of 3 patients were closed by local flap transfer. The intraoperative blood loss volume and blood transfusion, and length of hospital stay of patients were recorded. The incision healing and flap survival of patients were observed after operation. The recurrence of pressure ulcer and osteomyelitis, the appearance of the affected area, and the secondary dysfunction and deformity of the muscle flap donor site of patients were observed during followed up. Results: The intraoperative blood loss volume of the 8 patients was 220 to 900 (430±150) mL; 5 patients received intraoperative blood transfusion, of which 2 patients received 3 U suspended red blood cells and 3 patients received 2 U suspended red blood cells. The length of hospital stay was 18 to 29 (23.5±2.0) d for the 8 patients. In this group of patients, the incisions of 7 patients healed, while in one case, the incision suture was torn off during turning over and healed after secondary suture. The flaps survived well in 3 patients who underwent local flap transfer. During the follow-up period of 6-20 months, no recurrence of pressure ulcer or osteomyelitis occurred in 8 patients, the affected part had skin with good texture, mild pigmentation, and no sinus tract formation, and no secondary dysfunction or deformity occurred in the donor site. Conclusions: The en bloc resection and debridement combined with gluteus maximus muscle flap has good clinical effects on ischial tubercle pressure ulcer complicated with chronic osteomyelitis. Neither pressure ulcer nor osteomyelitis recurs post operation. The skin texture and appearance of the affected area are good, and the donor site has no secondary dysfunction or deformity.

Chinese Journal of Reparative and Reconstructive Surgery 2020;34(11):1382-1386
Objective: To observe the short-term effectiveness of Endobutton plate in the reconstruction of Lisfranc ligament in tarsometatarsal joint injury. Methods: Between March 2015 and July 2018, 18 patients with tarsometatarsal joint injuries were treated with Lisfranc ligament reconstruction by Endobutton plate. There were 12 males and 6 females with an average age of 32.5 years (range, 16-55 years). The causes of injury were traffic accident in 8 cases, falling from height in 3 cases, crushing by a heavy objective in 4 cases, and spraining in 3 cases. There were 10 cases of Myerson type A, 4 of type B1, 2 of type B2, 1 of type C1, and 1 of type C2. The interval between injury and operation ranged from 3 to 9 days (mean, 4.9 days). X-ray examination was performed regularly after operation to measure the distance between the first and the second metatarsal joints, and the visual analogue scale (VAS) score was used to evaluate the pain relief. At last follow-up, the reduction of tarsometatarsal joint was evaluated by measuring and comparing the height of the affected and healthy arches. The foot function was evaluated according to the American Orthopaedic Foot and Ankle Society (AOFAS) score. Results: The average follow-up time was 15.8 months (range, 10-28 months). All incisions healed by first intention. X-ray reexamination showed that there was no screw loosening or plate fracture. There were significant differences in the distance between the first and the second metatarsal joints and VAS score at 3 months after operation, before removal of the internal fixator, and at last follow-up when compared with preoperative values ( P<0.05). There was no significant difference between the time points after operation ( P>0.05). At last follow-up, there was no significant difference in the arch height between affected foot [(5.3±0.2) mm] and healthy foot [(5.4± 0.3) mm] ( t=1.798, P=0.810). The AOFAS score of foot function was 89.5±7.3 with excellent in 12 cases, good in 4 cases, and fair in 2 cases. The excellent and good rate was 88.9%. Conclusion: The reconstruction of Lisfranc ligament with Endobutton plate can stabilize the tarsometatarsal joint and achieve satisfactory foot function at early stage.

BackgroundLung cancer is a malignancy of high incidence rate and mortality in China. The fear of relapse can affect the patient's treatment compliance and reduce their quality of life. There have been previous studies on the relationship between fear of lung cancer relapse and disease perception, as well as disease perception and psychological flexibility. However, current research on the status quo of fear of lung cancer relapse and its correlation with illness perception and psychological flexibility is limited. ObjectiveTo explore the fear of cancer relapse and its relations with illness perception and psychological flexibility in patients with lung cancer, and to provide references for subsequent related clinical interventions. MethodsA total of 96 patients were selected as the research subjects, who were pathologically diagnosed with lung cancer and admitted to Fuyang People's Hospital from January 2021 to July 2022. Fear of Progression Questionnaire-Short Form (FoP-Q-SF), Brief Illness Perception Questionnaire (BIPQ) and Acceptance and Action Questionnaire-Ⅱ (AAQ-Ⅱ) were used for evaluation. Pearson correlation analysis was used to examine the correlation between scores of various scales, and multiple linear regression analysis was used to explore the influencing factors of relapse fear in lung cancer patients. ResultsThe total FoP-Q-SF score of lung cancer patients was (35.35±7.66) and a total of 65 cases (67.71%) had a FoP-Q-SF score≥34. As relevant analyses showed, the BIPQ total score of lung cancer patients was positively correlated with the total score, social family dimension score and physiological health dimension score of Fop-Q-SF (r=0.586, 0.445, 0.475, P<0.05), the AAQ-Ⅱ score was positively correlated with the total score, social family dimension score and physiological health dimension score of FoP-Q-SF (r=0.485, 0.652, 0.513, P<0.05). According to the results of single factor analysis and multiple linear regression analysis, age (β=-0.142, P<0.01), education level (β=-0.254, P<0.01), monthly household income (β=-0.527, P<0.01), illness perception (β=0.847, P<0.01) and psychological flexibility (β=0.781, P<0.01) are all factors influencing the fear of relapse in lung cancer patients. ConclusionMost lung cancer patients have a fear of recurrence. It is not only related to illness perception and psychological flexibility, but also influenced by factors including age, education level and monthly family income.[Funded by Special Research Project on Business Construction of National Clinical Research Base of Traditional Chinese Medicine under the State Administration of Traditional Chinese Medicine (number, JDZX2015074)]

ObjectiveTo investigate the correlation between plasma D-dimer level and severity of hepatitis B cirrhosis and its value in the diagnosis of portal vein thrombosis (PVT). MethodsA retrospective analysis was performed for the clinical data of 500 patients with hepatitis B cirrhosis who were hospitalized in The Fifth Medical Center of Chinese PLA General Hospital from January to December, 2018, and according to the plasma level of D-dimer, they were divided into normal group with 217 patients and elevated group with 283 patients. The correlations of plasma D-dimer level with Child-Pugh class and Model for End-Stage Liver Disease (MELD) score were compared between the two groups. The t-test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the Kruskal-Wallis H test was used for multiple groups comparison and further pairwise comparison. The chi-square test was used for comparison of categorical data between two groups. A Spearman correlation analysis was used to investigate correlation. The receiver operating characteristic (ROC) curve was used to evaluate the early warning performance of D-dimer level for PVT in patients with hepatitis B cirrhosis. ResultsThere were significant differences between the two groups in D-dimer level, alanine aminotransferase, aspartate aminotransferase, total bilirubin, albumin, Child-Pugh class, MELD score, and incidence rate of PVT (all P<0.05). The correlation analysis showed that plasma D-dimer level was positively correlated with Child-Pugh class and MELD score in both groups (r=0.463, 0.455, 0.214, and 0.756, all P<005). A total of 50 patients with hepatitis B cirrhosis were found to have PVT; the patients with PVT had a significantly higher D-dimer level that those without PVT [1.96 (0.82-4.91) mg/L vs 0.61 (0.19-1.54) mg/L, Z=-6.02, P<0.001]. The ROC curve analysis showed that D-dimer level had an area under the ROC curve of 0.758 (95% confidence interval: 0.719-0.796) at the optimal cut-off value of 0.76 mg/L. ConclusionPlasma D-dimer level is correlated with the severity of hepatitis B cirrhosis and can be used to predict the prognosis of patients with hepatitis B cirrhosis. The possibility of PVT should be considered in patients with an elevated D-dimer level.

OBJECTIVE:
To introduce a scout view scanning technique of back-forward bending CT (BFB-CT) in simulated surgical position for evaluating the remaining real angle and flexibility of thoracolumbar kyphosis secondary to old osteoporotic vertebral compression fracture.
METHODS:
A total of 28 patients with thoracolumbar kyphosis secondary to old osteoporotic vertebral compression fracture who met the selection criteria between June 2018 and December 2021 were included in the study. There were 6 males and 22 females with an average age of 69.5 years (range, 56-92 years). The injured vertebra were located at T 10-L 2, including 11 cases of single thoracic fracture, 11 cases of single lumbar fracture, and 6 cases of multiple thoracolumbar fractures. The disease duration ranged from 3 weeks to 36 months, with a median of 5 months. All patients received examinations of BFB-CT and standing lateral full-spine X-ray (SLFSX). The thoracic kyphosis (TK), thoracolumbar kyphosis (TLK), local kyphosis of injured vertebra (LKIV), lumbar lordosis (LL), and the sagittal vertical axis (SVA) were measured. Referring to the calculation method of scoliosis flexibility, the kyphosis flexibility of thoracic, thoracolumbar, and injured vertebra were calculated respectively. The sagittal parameters measured by the two methods were compared, and the correlation of the parameters measured by the two methods was analyzed by Pearson correlation.
RESULTS:
Except LL ( P>0.05), TK, TLK, LKIV, and SVA measured by BFB-CT were significantly lower than those measured by SLFSX ( P<0.05). The flexibilities of thoracic, thoracolumbar, and injured vertebra were 34.1%±18.8%, 36.2%±13.8%, and 39.3%±18.6%, respectively. Correlation analysis showed that the sagittal parameters measured by the two methods were positively correlated ( P<0.001), and the correlation coefficients of TK, TLK, LKIV, and SVA were 0.900, 0.730, 0.700, and 0.680, respectively.
CONCLUSION
Thoracolumbar kyphosis secondary to old osteoporotic vertebral compression fracture shows an excellent flexibility and BFB-CT in simulated surgical position can obtain the remaining real angle which need to be corrected surgically.

OBJECTIVE:
To explore the feasibility and early effectiveness of computer-simulated osteotomy based on the health-side combined with guide plate technique in the treatment of cubitus varus deformity in adolescents.
METHODS:
The clinical data of 23 patients with cubitus varus deformity who met the selection criteria between June 2019 and February 2023 were retrospectively analyzed. There were 17 males and 6 females, ranging in age from 4 to 16 years with an average of 8.5 years. The time from injury to operation was 1-4 years. The angle of distal humerus rotation was defined by humeral head posterior inclination angle using low radiation dose CT to scan the patient's upper extremity data at one time, and the preoperative rotation of the distal humerus on the affected side was (33.82±4.39)°. The CT plain scan data were imported into 9yuan3D digital orthopaedic system (V3.34 software) to reconstruct three-dimensional images of both upper extremities. The simulated operation was performed with the healthy upper extremity as the reference, the best osteotomy scheme was planned, overlapped and compared, and the osteotomy guide plate was prepared. The patients were followed up regularly after operation, and the formation of callus in the osteotomy area was observed by X-ray examination. Before and after operation, the carrying angle of both upper extremities (the angle of cubitus valgus was positive, and the angle of cubitus varus was negative) and anteversion angle were measured on X-ray and CT images. At the same time, the flexion and extension range of motion of elbow joint and the external rotation range of motion of upper extremity were measured, and Mayo score was used to evaluate the function of elbow joint.
RESULTS:
The operation time ranged from 34 to 46 minutes, with an average of 39 minutes. All patients were followed up 5-26 months, with a mean of 14.9 months. All the incisions healed by first intention after the operation; 2 patients had nail path irritation symptoms after Kirschner wire fixation, which improved after dressing change; no complication such as breakage and loosening of internal fixators occurred after regular X-ray review. Continuous callus formed at the osteotomy end at 4 weeks after operation, and the osteotomy end healed at 8-12 weeks after operation. At last follow-up, the carrying angle, anteversion angle, external rotation range of motion, and extension and flexion range of motion of the elbow joint of the affected side significantly improved when compared with preoperative ones ( P<0.05). Except for the extension range of motion of the healthy elbow joint ( P<0.05), there was no significant difference in other indicators between the two sides ( P>0.05). At last follow-up, the Mayo elbow score was 85-100, with an average of 99.3; 22 cases were excellent, 1 case was good, and the excellent and good rate was 100%.
CONCLUSION
Computer-simulated osteotomy based on health-side combined with guide plate technique for treating cubitus varus deformity in adolescents can achieve precise osteotomy, which has the advantages of short operation time and easy operation, and the short-term effectiveness is satisfactory.

OBJECTIVE To investigate the clinical effect of Budigafol combined with Staphylococcus and neisseria tablets in maintenance treatment of patients with stable moderate to severe chronic obstructive pulmonary disease (COPD). METHODS A total of 122 patients with stable moderate to severe COPD who were admitted to the infections diseases ward of the department of respiratory and critical care medicine in our hospital from October 1, 2021 to January 31, 2023 were divided into control group (n=61) and observation group (n=61) according to the random number table method. Patients in the control group were treated with Budigafol inhalation aerosol alone (2 presses each time, twice a day), and patients in the observation group were treated with Staphylococcus and neisseria tablets (1.2 mg each time, 3 times a day) on the basis of the control group. The treatment course of both groups was 3 months. The quality of life, exercise tolerance, lung function, inflammatory indexes, immune function, as well as the number of acute attacks of COPD and the occurrence of adverse reactions were compared between the two groups before and after treatment. RESULTS Control group and observation group shed 12 and 9 patients, respectively. After treatment, the 6 minute walking distance of the two groups of patients was significantly prolonged compared with that before treatment (P<0.05). The COPD assessment test questionnaire score, St George’s respiratory questionnaire score, the ratio of residual volume to total lung capacity, the fractional exhaled nitric oxide, the serum levels of C-reactive protein and interleukin-6 were significantly E-mail:13956685295@163.com decreased compared with those before treatment (P<0.05). The forced expiratory volume in one second (FEV1), the ratio E-mail:13966580920@163.com of FEV1 to forced vital capacity, the percentage of the measured value of carbon monoxide diffusion capacity to the predicted value, and the percentage of the measured value of FEV1 to the predicted value were significantly increased compared with those before treatment (P<0.05). The improvement of the above indicators in the observation group was significantly better than that in the control group (P<0.05). Compared with before treatment, there was no statistical significance in the immune function indexes of the control group or the serum levels of immunoglobulin A (IgA) and IgM in the observation group after treatment (P>0.05). The percentages of CD3+ , CD4+ , B lymphocytes and natural killer cells, the levels of CD4+/CD8+ and IgG were significantly increased in the observation group (P< 0.05), the percentage of CD8+ cells was significantly decreased (P<0.05), and the improvement degree of the observation group was significantly better than that of the control group (P<0.05). There was no significant difference in the number of acute exacerbations of COPD during the follow-up period and the incidence of adverse events during treatment between the two groups (P>0.05). CONCLUSIONS Budigafol combined with Staphylococcus and neisseria tablets can effectively improve the immune function of patients with stable moderate to severe COPD, further reduce the level of inflammation, and improve their exercise tolerance and their quality of life with good safety.

Objective :
To analyze the application value of metagenomic next-generation sequencing (mNGS) in the detection of pathogenic bacteria in pulmonary infection ,and to provide a theoretical basis for clinical diagnosis.
Methods :
A retrospective study was conducted on 161 patients with suspected pulmonary infection,and samples of bronchoalveolar lavage fluid ,sputum and lung tissue were collected specimens ,pleural effusion and blood were simultaneously subjected to routine culture,respiratory pathogen nucleic acid detection and pathogenic microorgan- ism mNGS detection.The sensitivity ,specificity,positive predictive value ,and negative predictive value of the three detection methods were calculated respectively to evaluate the clinical application value of mNGS.
Results:
Among 161 patients with suspected pulmonary infection,113 cases were finally confirmed as pulmonary infection. Among the 161 patients enrolled,the sensitivity and negative predictive value of mNGS were improved compared with routine culture and nucleic acid detection of respiratory pathogens,and the difference was statistically signifi- cant(P<0. 001) .Although the specificity of mNGS was higher than that of respiratory pathogen nucleic acid de- tection,the difference was not statistically significant.The positive predictive value of mNGS was the highest,and was higher than that of respiratory pathogen nucleic acid detection,but had no statistical significance compared with conventional culture.
Conclusion
The sensitivity of mNGS in the diagnosis of pathogenic microorganisms in pul- monary infection is higher than that of conventional culture and nucleic acid detection of respiratory pathogens, which reduces the false negative rate of diagnosis and has a better comprehensive evaluation ; conventional culture detection has low sensitivity,but high specificity ; respiratory pathogen nucleic acid detection compared with con- ventional culture,the sensitivity is improved,but the specificity decreased.
