OBJECTIVES: To study clinical manifestations and gene mutation features of neonates with centronuclear myopathy. METHODS: A retrospective analysis was conducted on the medical data of 5 neonates with centronuclear myopathy diagnosed in the Neonatal Intensive Care Unit of Children's Hospital, Zhejiang University School of Medicine from January 2020 to August 2024. The data included gender, gestational age, birth weight, Apgar score, clinical manifestations, creatine kinase level, electromyography, genetic testing results and the outcomes of the infants. RESULTS: All 5 male neonates had a history of postpartum asphyxia and resuscitation. They all presented with hypotonia, myasthenia, and respiratory failure; two neonates also had swallowing dysfunction. Of the five neonates, three had normal creatine kinase levels, while two had slightly elevated levels. Electromyography was performed for three neonates, among whom two had myogenic damage. MTM1 gene mutations were identified by genetic testing in all five neonates, including two nonsense mutations and three missense mutations, among which one variant had not been previously reported. Four mutations were inherited from the mother, and the other one was a de novo mutation. The five neonates showed no clinical improvement following treatment, failed weaning from mechanical ventilation, and ultimately died after withdrawal of life-sustaining therapy. CONCLUSIONS Centronuclear myopathy caused by MTM1 gene mutation often has a severe phenotype and a poor prognosis, and it should be considered for neonates with hypotonia and myasthenia after birth. Genetic testing should be performed as soon as possible.

Objective To investigate the effect of exosomal miR-146a-5p expression on gray matter volume in patients with major depressive disorder(MDD).Methods A total of 113 MDD patients(MDD group)and 107 healthy controls(HC)(HC group)were selected.Peripheral blood was collected and exosomes were isolated to quantify miR-146a-5p expression.Brain high-resolution T1 WI images of MDD and HC were obtained via MR,and gray matter volume was computed via SPM12 software.The interaction effect of"Depression×miR-146a-5p expression"on gray matter volume was analyzed using SPM's Flexible factorial design,and the between-group difference was assessed by extracting the mean value,thus to analyze whether MDD-related gray matter volume abnormalities were dependent on miR-146a-5p expression.Results Exosomal miR-146a-5p expression was significantly elevated in MDD group compared to HC group.Voxel-based factorial analysis revealed a relationship between high miR-146a-5p expression in MDD group and reduced gray matter volume in the anterior and posterior cingulate cortices(independent voxel threshold P＜0.001,AlphaSim corrected),and a significantly reduced gray matter volume as compared with HC group was detected in the two regions.Conclusion The exosomal miR-146a-5p is overexpressed in patients with MDD and may be associated with specific cortical atrophy in patients with MDD.

Objective To evaluate the effects of transcutaneous electrical acupoint stimulation(TEAS)combined with Chinese medicine emotional intervention on immune function and psychological stress in patients undergoing laparoscopic radical rectal cancer surgery.Methods A total of 100 patients hospitalized for laparoscopic radical surgery for rectal cancer were randomly divided into 4 groups of Group A,B,C,and D,25 patients in each group.Group A was given TEAS for 30 minutes before anesthesia,Group B was given TEAS continuously until the end of the surgery,Group C was given TEAS for 30 minutes and Chinese medicine emotional intervention before anesthesia,Group D was given TEAS continuously until the end of the surgery together with Chinese medicine emotional intervention.TEAS was performed at bilateral Zusanli(ST36)points,bilateral Sanyinjiao(SP6)points,Baihui(GV20)points,bilateral Neiguan(PC6)points.The changes of perioperative outcomes and the changes of parameters associated with the immune function,molecular mechanism of Th1/Th2 cells,and psychological stress response before the surgery and 3 days after the surgery in each group were observed.Moreover,the occurrence of adverse reactions in each group was compared.Results(1)The differences of perioperative outcomes operation time,bleeding volume and infusion amount were not statistically significant among the 4 groups(P＞0.05).The Sufentanil dosage,Remifentanil dosage,postoperative awakening time,and 24-hour postoperative pain Visual Analogue Scale(VAS)scores of group D were lower than those of Groups A,B,and C(P＜0.05),and the above indexes of group B and group C were all lower than those of Group A(P＜0.05).(2)Three days after the surgery,the levels of immune function indicators of T lymphocyte subsets CD3+,CD4+ and natural killer(NK)cells in Group D were higher than those in Groups A,B,and C(P＜0.05),while the above indexes in Groups B and C were higher than those in Group A(P＜0.05).(3)Three days after the surgery,the levels of parameters associated with the molecular mechanism of Th1/Th2 cells such as interleukin 2(IL-2)and interferon gamma(IFN-γ)in Group D were higher(P＜0.05),and the serum interleukin 10(IL-10)level was lower than those in Groups A,B,and C(P＜0.05);the serum IL-2 and IFN-γ levels in Group B and C were higher(P＜0.05)and serum IL-10 level was lower than those in Group A(P＜0.05).(4)Three days after the surgery,the scores of the psychological stress response indicators of self-rating anxiety scale(SAS)and self-rating depression scale(SDS)in Group D were lower than those in Groups A,B,and C(P＜0.05),while the above scores in Groups B and C were lower than those in Group A(P＜0.05).(5)In Group A,there was one case of nausea and vomiting;in Group B,there were two cases of nausea and vomiting and one case of dizziness;no adverse reaction occurred in Group C,and there was one case of nausea and vomiting in Group D.The incidences of adverse reactions in Groups A,B,C and D were 4.0%(1/25),12.0%(3/25),0.0%(0/25),and 4.0%(1/25),respectively.The intergroup comparison showed no statistically significant difference among the 4 groups(χ2 = 0.400,P = 0.527).Conclusion In treating patients undergoing laparoscopic radical surgery for rectal cancer,TEAS combined with Chinese medicine emotional intervention can effectively regulate the perioperative immune function,reduce the stress response,and alleviate the anxiety of the patients.Moreover,the therapy exerts certain analgesic effect,which leads to the reduction of the dosage of opioids and the increase of perioperative comfort and surgical tolerance of the patients.

OBJECTIVE: To analyze the safety and effectiveness of 3D printing prefabricated nail path model assisted lumbosacral hemivertebra orthopaedic surgery. METHODS: A retrospective analysis was performed on 8 patients with lumbosacral hemivertebra deformity admitted from January 2016 to July 2021, including 3 males and 5 females, aged 6 to 15 at the time of surgery. The hemivertebra of 4 cases located on the left side and 4 cases on the right side. The hemivertebra of 1 case located at L_2,3, 2 cases at L_3,4, 2 cases at L_4,5, and 3 cases at L₅S₁. Four cases were fully segmented hemivertebra and 4 cases were incomplete segmented hemivertebra. The patient CT data was imported into Mimics 21.0 software for modeling, and then the model data was imported into 3-Matic software. The vertebra requiring screw placement was selected to simulate the optimal screw placement angle and length, and the model was printed for preoperative planning and intraoperative guidance. All patients underwent orthopedic surgery with the aid of 3D printing preset nail path model. The safety and effectiveness of the 3D printing prefabricated nail tunnel model assisted lumbosacral hemivertebra orthopaedic surgery was evaluated by comparing the imaging parameters of the patients. The main outcome measures were the Cobb angle of the main curve, the Cobb angle of the proximal compensatory curve, the coronal balance index C₇ plumb line-center sacral vertical line(C₇PL-CSVL), the accuracy of nail placement, and the correction rate of scoliosis before surgery, 1 week and 1 year after surgery. RESULTS: All of 8 patients were followed up for 13 to 31 months. A total of 98 pedicle screws were placed in 8 patients. The number of pedicle screw grades A, B, C, D, E was 38, 46, 10, 4, 0 screws. The screws of grade A and B were defined as good position, the accuracy rate of screw placement was 85.7%. The Cobb angle of the main curve were 21° to 38° before operation, 5° to 11° at 1 week after operation, 7°to 12° at 1 year after operation. The Cobb angle of the proximal compensatory curve were 16° to 39° befoer operation, 7° to 12 °at 1 week after operation, 7° to 14° at 1 year after operation, the correction effect remained good with no correction loss. The coronal balance index C7PL-CSVL were 20 to 35 mm before operation, 11 to 18 mm at 1 week after operation, 10 to 16 mm at 1 year after operation, the coronal imbalance improved. The scoliosis correction rate was 65.6% to 84.2% 1 week after surgery, and 61.9% to 81.6% 1 year after surgery. CONCLUSION The use of 3D printing prefixed nail tunnel model in lumbosacral hemivertebra osteotomy is safe and effective, and can significantly improve patients' local deformities. It is a reliable method to assist lumbar sacral hemivertebra osteotomy.

OBJECTIVE: To study the effect of ultrasound-guided fascia iliaca compartment block on perioperative analgesia and postoperative complications in geriatric patients with hip fractures. METHODS: A total of 127 elderly patients undergoing hip fracture surgery from January 2021 to September 2021 were randomized to receive ultrasound-guided continuous fascia iliaca compartment block(group F) either intravenous analgesia control group(group C). There were 62 cases in group F, including 19 males and 43 females with an average age of (82.4±7.2) years old ranging from 66 to 95 years old, involving 25 femoral neck fractures and 37 femoral intertrochanteric fractures. There were 65 cases in control group, including 18 males and 47 females, with an average age of (81.4±8.7) years old ranging from 65 to 94 years old, involving 29 femoral neck fractures and 36 femoral intertrochanteric fractures. The visual analogue scale(VAS), minimental state examination (MMSE), observer's assessment of alertness/sedation(OAA/S) scale, modified Bromage score, postoperative complications and general conditions during hospitalization in two groups were observed. RESULTS: The resting and exercise VAS at 30 min after block, anesthesia placement and 6, 24 and 48 h after surgery were lower than those in group C(P<0.05). In group F, MMSE scores at 12 h before surgery, and 1, 3 d after surgery and OAA/S scores at 3 d after surgery were higher than those in group C(P<0.05). The incidence of adverse effects and the number requiring additional analgesia were lower than those in group C(P<0.05). Group F had better perioperative analgesia satisfaction and hospital stay than group C(P<0.05). But there was no significant difference regarding Bromage score and 30-day mortality between two group(P>0.05). CONCLUSION Ultrasound-guided continuous fascia iliacus space block was safe and effective for elderly patients with hip fracture, and could significantly reduce perioperative pain, improve postoperative cognitive function, and reduce postoperative complications, thereby shortening hospital stay and improving the quality of life during hospitalization.

Pancreatic cancer is a highly malignant tumor with a poor prognosis. It is very hard to treat pancreatic cancers for their high heterogeneity, complex tumor microenvironment, and drug resistance. Currently, gemcitabine plus nab-paclitaxel, capecitabine and FOLFIRINOX are standard chemotherapy for resectable or advanced metastatic pancreatic cancer. Considering the limited efficacy and toxic side effects of chemotherapy, targeted and immune drugs have gradually attracted attention and made some progress. In this article, we systematically reviewed the chemotherapeutic drugs, targets and related targeted drugs, and immunotherapy drugs for pancreatic cancer.

Objective: To evaluate the advantages and safety of Plerixafor in combination with granulocyte colony-stimulating factor (G-CSF) in autologous hematopoietic stem cell mobilization of lymphoma. Methods: Lymphoma patients who received autologous hematopoietic stem cell mobilization with Plerixafor in combination with G-CSF or G-CSF alone were obtained. The clinical data, the success rate of stem cell collection, hematopoietic reconstitution, and treatment-related adverse reactions between the two groups were evaluated retrospectively. Results: A total of 184 lymphoma patients were included in this analysis, including 115 cases of diffuse large B-cell lymphoma (62.5%) , 16 cases of classical Hodgkin's lymphoma (8.7%) , 11 cases of follicular non-Hodgkin's lymphoma (6.0%) , 10 cases of angioimmunoblastic T-cell lymphoma (5.4%) , 6 cases of mantle cell lymphoma (3.3%) , and 6 cases of anaplastic large cell lymphoma (3.3%) , 6 cases of NK/T-cell lymphoma (3.3%) , 4 cases of Burkitt's lymphoma (2.2%) , 8 cases of other types of B-cell lymphoma (4.3%) , and 2 cases of other types of T-cell lymphoma (1.1%) ; 31 patients had received radiotherapy (16.8%) . The patients in the two groups were recruited with Plerixafor in combination with G-CSF or G-CSF alone. The baseline clinical characteristics of the two groups were basically similar. The patients in the Plerixafor in combination with the G-CSF mobilization group were older, and the number of recurrences and third-line chemotherapy was higher. 100 patients were mobilized with G-CSF alone. The success rate of the collection was 74.0% for one day and 89.0% for two days. 84 patients in the group of Plerixafor combined with G-CSF were recruited successfully with 85.7% for one day and 97.6% for two days. The success rate of mobilization in the group of Plerixafor combined with G-CSF was substantially higher than that in the group of G-CSF alone (P=0.023) . The median number of CD34(+) cells obtained in the mobilization group of Plerixafor combined with G-CSF was 3.9×10(6)/kg. The median number of CD34(+) cells obtained in the G-CSF Mobilization group alone was 3.2×10(6)/kg. The number of CD34(+) cells collected by Plerixafor combined with G-CSF was considerably higher than that in G-CSF alone (P=0.001) . The prevalent adverse reactions in the group of Plerixafor combined with G-CSF were grade 1-2 gastrointestinal reactions (31.2%) and local skin redness (2.4%) . Conclusion: The success rate of autologous hematopoietic stem cell mobilization in lymphoma patients treated with Plerixafor combined with G-CSF is significantly high. The success rate of collection and the absolute count of CD34(+) stem cells were substantially higher than those in the group treated with G-CSF alone. Even in older patients, second-line collection, recurrence, or multiple chemotherapies, the combined mobilization method also has a high success rate of mobilization.

Objective: To study the correlation between ceramic and chronic obstructive pulmonary disease (COPD), and explore its related risk factors. Methods: In January 2021, five representative ceramic enterprises were selected from Chancheng District, Nanhai District, Gaoming District and Sanshui District of Foshan City. The ceramic workers who came to Chancheng Hospital of Foshan First People's Hospital for physical examination from January to October 2021 were selected as the research objects, and 525 people were included. Conduct questionnaire survey and pulmonary function test. Logistic regresion was performed to analyze the influencing facters of COPD among ceramic workers. Results: The subjects were (38.51±1.25) years old, 328 males and 197 females, and the detection rate of COPD was 9.52% (50/525). The incidence of respiratory symptoms such as dyspnea, chronic cough, wheezing and chest tightness, the detection rates of abnormal lung age, abnormal lung function and COPD in males were higher than those in females (P<0.05). The logistic regression analysis showed that male, age, working years, smoking status and family history of COPD were the risk factors for COPD among ceramic workers (P<0.05) . Conclusion: The ceramic workers are the high risk population of COPD. We should do a good job in health education, and do a regular physical examination to find the changes of lung function in time, and prevent the occurrence of COPD as soon as possible.

A cross-sectional study was conducted to estimate the age-stratified normal levels and age-related changes in the risk predictors of benign prostatic hyperplasia (BPH) progression. A total of 4706 male participants aged 40 years or older in Zhengzhou (China) were enrolled. The values of the International Prostate Symptom Score (IPSS), prostate-specific antigen (PSA), prostate volume (PV), and postvoid residual urine volume (PVR) significantly increased with age. Nonlinear relationships between age and IPSS scores ≥8 (P for nonlinearity = 0.046), PSA level ≥1.6 ng ml^-1, PV ≥31 ml, or PVR ≥39 ml (all P for nonlinearity <0.001) were observed. After the age of 61 years, the risk indicators related to BPH progression were positively correlated with age (odds ratio [OR] >1), regardless of the predictors of the IPSS score, PSA level, PV, or PVR; and the OR values increased gradually. Therefore, after the age of 61 years, the risk predictors related to BPH progression were positively correlated with age.

Background In mainland China, patients with neovascular age-related macular degeneration (nAMD) have approximately an 40% prevalence of polypoidal choroidal vasculopathy (PCV). This disease leads to recurrent retinal pigment epithelium detachment (PED), extensive subretinal or vitreous hemorrhages, and severe vision loss. China has introduced various treatment modalities in the past years and gained comprehensive experience in treating PCV.Methods A total of 14 retinal specialists nationwide with expertise in PCV were empaneled to prioritize six questions and address their corresponding outcomes, regarding opinions on inactive PCV, choices of anti-vascular endothelial growth factor (anti-VEGF) monotherapy, photodynamic therapy (PDT) monotherapy or combined therapy, patients with persistent subretinal fluid (SRF) or intraretinal fluid (IRF) after loading dose anti-VEGF, and patients with massive subretinal hemorrhage. An evidence synthesis team conducted systematic reviews, which informed the recommendations that address these questions. This guideline used the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) approach to assess the certainty of evidence and grade the strengths of recommendations. Results The panel proposed the following six conditional recommendations regarding treatment choices. (1) For patients with inactive PCV, we suggest observation over treatment. (2) For treatment-na?ve PCV patients, we suggest either anti-VEGF monotherapy or combined anti-VEGF and PDT rather than PDT monotherapy. (3) For patients with PCV who plan to initiate combined anti-VEGF and PDT treatment, we suggest later/rescue PDT over initiate PDT. (4) For PCV patients who plan to initiate anti-VEGF monotherapy, we suggest the treat and extend (T&E) regimen rather than the pro re nata (PRN) regimen following three monthly loading doses. (5) For patients with persistent SRF or IRF on optical coherence tomography (OCT) after three monthly anti-VEGF treatments, we suggest proceeding with anti-VEGF treatment rather than observation. (6) For PCV patients with massive subretinal hemorrhage (equal to or more than four optic disc areas) involving the central macula, we suggest surgery (vitrectomy in combination with tissue-plasminogen activator (tPA) intraocular injection and gas tamponade) rather than anti-VEGF monotherapy. Conclusions Six evidence-based recommendations support optimal care for PCV patients' management.
