Objective:A nationwide multi-center and large sample survey was conducted to compare the validity of the Mini International Neuropsychiatric Interview (Hypo-) Manic Episode with Mixed Features-DSM-5 Module (MINI-M) questionnaire and the Clinically Useful Depression Outcome Scale Supplemented with Questions for the DSM-5 Mixed Features Specifier (CUDOS-M) depression subscale in identifying mixed features in patients experiencing (hypo-) manic episodes.Methods:Using a convenience sampling method, 366 patients with bipolar disorder experiencing acute (hypo-) manic episodes who met the inclusion and exclusion criteria were recruited. The diagnosis of "with mixed features" was based on the DSM-5 criteria for mixed features. The predictive validity of the MINI-M questionnaire and the CUDOS-M depression subscale to screen mixed features was analyzed using the receiver operating characteristic (ROC) curve. Additionally, the difference in area under the ROC curve (AUC) between the two instruments was compared.Results:The AUC for the MINI-M questionnaire and the CUDOS-M depression subscale in screening mixed features were 0.79 (95 %CI=0.75-0.84) and 0.81 (95 %CI=0.77-0.86), respectively. There was no statistically significant difference in AUC between the two measurements ( Z=-1.19, P>0.05). Among patients with acute (hypo-) manic episodes, 45.9% (168/366) presented with mixed features according to the DSM-5 criteria, while the corresponding figures were 43.7% (160/366) using the MINI-M questionnaire (total score≥3) and 42.1% (154/366) using the CUDOS-M depression subscale (total score≥20). Screening results were comparable among the three measures. Conclusion:Mixed features are common among patients experiencing acute (hypo-) manic episodes. The MINI-M questionnaire and the CUDOS-M depression subscale demonstrate equivalent validity in identifying mixed features.

【Objective】 To study the changes of platelet components(PC), apheresis platelets (AP) and pooled platelet concentrates (PPC) production of 19 provincial blood centers before and during the COVID-19 epidemic. 【Methods】 The data related to the collection of AP and the preparation of PPC from 2016 to 2021 of 19 provincial blood centers was collected. The production of PC, AP and PPC during the four years before the epidemic (i.e. 2016-2019) and during the COVID-19 epidemic (i.e. 2020 and 2021) were calculated respectively, and the change of production was analyzed. 【Results】 The total production of PC in 19 blood centers steadily increased from 2016 to 2019, with a decrease of 4.16% in 2020 and an increase of 15.60% in 2021, exceeding the output before the COVID-19 epidemic. In 2020, the production of PC of 42.11% (8/19) blood centers decreased compared with 2019, while 94.74% (18/19) in 2021 increased compared with 2020. The changes of AP output was basically consistent with the trend of PC. The total production of PPC in 2017 and 2018 both doubled compared to the previous year, while decreased by 67.98% in 2019, increased by 30.38% in 2020 and decreased by 27.08% in 2021. 【Conclusion】 The total production of PC kept increasing steadily between 2016 and 2019, but decreased in 2020 under the COVID-19 epidemic, with some blood centers being significantly affected. In 2021, with the strong support from government and various measures by blood centers, the total production of PC increased.

Objective:To investigate the application value of mixed reality technology in surgical conversation of laparoscopy radical resection of gastric cancer.Methods:The prospective randomized controlled study was conducted. There were 80 family members of patients with gastric cancer who were admitted to Nanfang Hospital of Southern Medical University from June 2021 to December 2022 being selected as subjects. All patients underwent laparoscopic radical resection of gastric cancer. Based on random number table, all subjects were allocated into the control group and the experiment group. Subjects in the control group performed routine surgical conversation and subjects in the experiment group performed surgical conversation based on mixed reality technology. Observation indicators: (1) baseline data of the subjects; (2) anxiety assessment of the subjects. Measurement data with normal distribution were represented as Mean± SD, and the independent sample t test was used for inter-group comparison. Repeated measurement data were analyzed using the repeated ANOVA. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data was conducted using the Wilcoxon rank sum test. Results:(1) Baseline data of the subjects. A total of 80 subjects were selected for eligibility, including 40 subjects in the control group and 40 subjects in the experi-ment group. There were 44 males and 36 females, aged (40±9)years. The gender (male, female), age, education background (primary school education, middle school education, high school education, junior college education, undergraduate education, postgraduate education) were 23, 17, (39±9)years, 1, 3, 9, 16, 9, 2 in subjects of the control group, versus 25, 15, (42±10)years, 0, 8, 6, 11, 14, 1 in subjects of the experiment group, showing no significant difference in the above indicators between the two groups ( χ2=0.20, t=?1.64, Z=?0.10, P>0.05). (2) Anxiety assessment of the subjects. The scores of self-rating Anxiety Scale (SAS) and Hospital Anxiety Scale (HADS) before surgical conversation, after surgical conversation, after surgery were 41±10 and 26±5, 49±11 and 32±3, 40±13 and 15±8 in subjects of the control group, versus 44±9 and 23±3, 66±16 and 28±6, 34±14 and 8±3 in subjects of the experiment group, showing significant differences in the above indicators between the two groups ( FSAS组间=8.83, FSAS时间=40.41, FSAS交互=12.21, FHADS组间=32.42, FHADS时间=321.28, FHADS交互=6.15, P<0.05).

OBJECTIVE: To review the research progress in biotherapy of rotator cuff injury in recent years, in order to provide help for clinical decision-making of rotator cuff injury treatment. METHODS: The literature related to biotherapy of rotator cuff injury at home and abroad in recent years was widely reviewed, and the mechanism and efficacy of biotherapy for rotator cuff injury were summarized from the aspects of platelet-rich plasma (PRP), growth factors, stem cells, and exosomes. RESULTS: In order to relieve patients' pain, improve upper limb function, and improve quality of life, the treatment of rotator cuff injury experienced an important change from conservative treatment to open surgery to arthroscopic rotator cuff repair. Arthroscopic rotator cuff repair plus a variety of biotherapy methods have become the mainstream of clinical treatment. All kinds of biotherapy methods have ideal mid- and long-term effectiveness in the repair of rotator cuff injury. The biotherapy method to promote the healing of rotator cuff injury is controversial and needs to be further studied. CONCLUSION All kinds of biotherapy methods show a good effect on the repair of rotator cuff injury. It will be an important research direction to further develop new biotherapy technology and verify its effectiveness.

Objective:This study investigates the difference in the detection rate and symptomatology between ICD-10 and DSM-5 diagnostic criteria for bipolar disorder with mixed states.Methods:Based on the Phase Ⅰ (2012) and Phase Ⅱ (2021) databases of National Bipolar Mania Pathway Survey (BIPAS), patients with bipolar disorder were included. General demographic data, clinical characteristics, symptomatic phenotypes, and mixed characteristics were retrieved. The detection rates and symptomatic performances of patients with or without mixed states in Phase Ⅰ and Ⅱ were compared using the chi-square test.Results:For patients with mixed states, the detection rate during Phase Ⅱ (2021) using DSM-5 (18.79%, 199/1 059) criteria was significantly higher than that during Phase Ⅰ (2012) using ICD-10 (6.78%, 199/2 934; χ 2=125.05, P<0.001). Whether using ICD-10 or DSM-5 criteria, patients with mixed states had a significantly higher frequency of multiple symptomatic manifestations. Conclusion:The DSM-5 diagnostic criteria generate a high detection rate for bipolar disorder with mixed states. The clinical phenotypes of bipolar disorder with mixed states vary significantly using different diagnostic tools.

Objective To analyze the prognostic factors in the patients with HER2-positive breast cancer adjuvant treated with trastuzumab.Methods We conducted a retrospective analysis of clinical data of 1 246 patients diagnosed with HER2-positive breast cancer between January 2009 and December 2019 who received treatment with trastuzumab.We investigated the factors impacting their prognosis by the Log-rank test univariate analysis and multivariate COX regression analysis.Results HER2-positive patients treated with trastuzumab had a poor prognosis in pT2-3(HR=2.10,P=0.003),pN2-3(HR=2.81,P<0.001),and no endocrine therapy(HR=2.50,P<0.001),and that had a better prognosis combined with taxane or other chemotherapy regimens(HR=0.40,P=0.017).We divided the patients into two subgroups according to the status of lymph node metastasis,and we found that in the negative lymph nodes group the patients with pT2-3 stage had poor prognosis(P=0.020),while the patients combined with taxane or other chemotherapy had better prognosis(P=0.032).In the positive lymph nodes group the patients with pT2-3 stage and no endocrine therapy had poor prognosis(P=0.012,P=0.001).Conclusions The patients with HER2-positive breast cancer treated with trastuzumab can be managed in different categories,for individuals without lymph node involvement and small tumor sizes,combining therapy with non-anthracycline chemotherapy is preferable for achieving improved outcomes,for patients with lymph node metastasis and large tumor sizes,if chemotherapy options are available,it is more recommended to use an anthracycline-free regimen to ensure the same prognosis while reducing the harm caused by the toxic side effects of chemotherapy.

Objective:To preliminarily estimate and study the effect of nucleic acid testing in blood screening on the residual risk (RR) of transfusion transmitted HBV infection (TTI HBV).Methods:Using the NAT yield/WP ratio model and adopting the relevant data of information management system of practice comparison working party in the Mainland of China, this paper analyzed the trend of the RR of TTI HBV among 18 blood centers from 2015 to 2019 in China, and compared the impact of two kinds of blood screening strategies which were ELISA+ ID-NAT/MP-NAT (individual-donation nucleic acid testing or mini-pool nucleic acid testing) and ELISA + MP-NAT on RR in 2019.Results:The overall trends of the 5-year RR of HBV among 18 blood centers showed by trend chi square test were NAT single positive rate trend χ2= 39.42( P<0.01) and residual risk trend χ2= 279.792( P<0.01); The influence on RR from the differences of ELISA+ ID-NAT/MP-NAT and ELISA+ MP-NAT was statistically significant, and chi square test showed that χ2= 7.4( P<0.01). Conclusions:Since the implementation of nucleic acid testing in the blood screening in China from 2015, the residual risk of transfusion transmitted HBV infection has decreased year by year. The observed two blood screening strategies which dominated in China may lead to discrepancy in the residual risk of TTI.

Objective:To explore the etiology, clinical diagnosis and treatment strategy of Lesch Nyhan syndrome.Methods:We retrospectively analyzed 2 patients with severe dyskinesia, mental retardation and complicated renal calculi who were admitted to the first people's Hospital of Zhengzhou in August 2019. Case 1, male, 9 years old, had multiple urinary calculi for 1 year. The patient came to the local hospital because double multiple kidney stones and bladder stonesa year ago. The patient had been treated with transurethral holmium laser lithotripsy for bladder stones. The results of infrared spectrum showed that the bladder stone was anhydrous uric acid stone. A week ago, color Doppler ultrasound showed multiple kidney stones and bladder stones. The patient was underdeveloped, mentally retarded and had a full-term cesarean section. There was no history of hypoxia, asphyxia and rescue of the patient. He had the following clinical manifestations: In the waking state, he was no language response to any stimulation. The nasolabial fold on the right was shallow and the corner of the mouth was oblique to the left. He lost the large movements such as lifting head, sitting alone, standing. The trunk showed torsion spasticity, limb muscle strength 2-3, limbs showing spastic hypertonia, limb joints stiff, hands showing fist-like, no involuntary movement and muscle fasciculation. The biceps reflex and knee tendon reflex were not elicited, and the pathological reflex was positive. Serum uric acid was 517 μmol/L. The Case 2 came from the same family, male, 6 years old, had the similar symptoms to his elder brother case 1. The family members complained on behalf of the child about intermittent fever for more than 2 years. The imaging examination of case 2 revealed kidney stones. Serum uric acid was 373 μmol/L. Whole Exome Sequencing and Sanger Sequencing were used to find the genetic causes of the two siblings. The NCBI-Homologene database was used to find the homologous sequence of the human HPRT1 gene, and the human HPRT1 gene sequence was compared with other species to analyze the protein conservation. The online website PredictProtein (http: //www.predactprotein) was used to predict the two-dimensional structure of the HPRT1 gene. The reported cases were summarized and same with the treatment plan.Results:A De novo mutation [c.571T>G(p.Tyr191Asp)] was found in the HPRT1 gene of the child, which was inherited from the mother. Lesch Nyhan syndrome can be diagnosed by the results of gene examination combined with clinical manifestations. The amino acid Tyr at the 191 position and the amino acids before and after it were highly conserved. Amino acid 191 was involved in the β-strand of the protein. We treated the patients with the lowest dose of allopurinol and children's conventional dose of potassium sodium bicitrate granules, and low purine diet. After 3 months of treatment, the serum uric acid was decreased, and the urinary calculi did not increase significantly.Conclusions:Combining with the clinical manifestations of children, HPRT1 gene might be the cause of pediatric disease and the two siblings could be diagnosed as Lesch-Nyhan syndrome. For such patients, the lowest dose of allopurinol and children's conventional dose of potassium sodium hydrogen citrate granule combined with diet could be more effective.
