ABSTRACT
A total of 82 patients and healthy subjects in the First Affiliated Hospital of Sun Yat-sen University from March to August 2023 were recruited. The cohort consisted of 43 patients with head and neck squamous cell carcinoma (HNSCC) and 39 non-cancer patients or healthy subjects. There were 63 males and 19 females, with a median age of 62 (46, 67) years. The levels of folate receptor-positive circulating tumor cells (FR+CTCs) in the blood of HNSCC patients and non-cancer/healthy subjects were 12.4 (8.5, 17.8) floate unit (FU)/3 ml and 5.0 (3.8, 6.6) FU/3 ml, respectively, with a statistically significant difference (P<0.001). The area under the receiver operating characteristic (ROC) curve for FR+CTCs levels was 0.937 (95%CI: 0.888-0.986, P<0.001), with a cut-off value of 7.4 FU/3 ml determined by the maximum Youden index. At this cut-off value, the sensitivity and specificity of FR+CTCs for diagnosing HNSCC were 90.70% and 89.74%, respectively. The current study suggests that FR+CTCs could be used as a liquid biopsy marker for the screening and diagnosis of HNSCC.

Objective: To investigate the risk factors for the occurrence of laryngopharyngeal reflux disease in the aged, and to analyze the characteristics of patients with pneumonia. Methods: Patients who underwent 24-hour laryngopharyngeal pH monitoring from June 2020 to July 2022 and the positive patients of those who underwent 24-hour esophageal pH monitoring from March 2017 to July 2022 at the Second Medical Center of the PLA General Hospital were enrolled retrospectively. Positive results of 24-hour laryngopharyngeal reflux monitoring were in the laryngopharyngeal reflux group, and the negative results were in the non-laryngopharyngeal reflux group. Patients with pneumonia and simple gastroesophageal reflux disease were in the esophageal reflux pneumonia group, and patients with pneumonia and simple laryngopharyngeal reflux disease were in the laryngopharyngeal reflux pneumonia group. Patients' basic data, co-morbidities, drug use and relevant examination and test results were collected. Multivariate logistic regression analysis was used to analyze the risk factors of laryngopharyngeal reflux disease in the aged and its relationship with pneumonia. Results: A total of 80 patients with 24-hour laryngopharyngeal pH monitoring were enrolled finally, including 34 cases, all male, aged (73±12) years, in the laryngopharyngeal reflux group, and 46 cases [44 males, 2 females, aged (78±11) years] in the non-laryngopharyngeal reflux group. Multivariate logistic regression analysis showed that the risk factors of laryngopharyngeal reflux disease in the aged included age ≤70 years (OR=13.07, 95%CI: 2.53-67.68), body mass index (BMI) (OR=1.37, each additional 1 kg/m2, 95%CI: 1.03-1.83), use of antipsychotic drugs (OR=8.00, 95%CI: 1.40-45.73) and calcium channel blockers (OR=5.27, 95%CI: 1.13-24.53) (all P<0.05). The protective factors of the laryngopharyngeal reflux disease in the aged included antacids (OR=0.19, 95%CI: 0.04-0.90, P=0.035). The incidence of pneumonia was higher in the laryngopharyngeal reflux group compared with the non-laryngopharyngeal reflux group [44.1% (15/34) vs 21.7% (10/46), P=0.033]. The esophageal reflux pneumonia group included 32 cases [31 males and 1 females, aged (84±12) years]. The laryngopharyngeal reflux pneumonia group included 15 cases [ 15 males, aged (79±11) years]. Compared to the patients in the laryngopharyngeal reflux pneumonia group, the patients in the esophageal reflux pneumonia group had a longer course of antibiotics [(27.7±27.0) vs (14.6±13.9) days, P=0.034], a higher frequency of seizure frequency [(4.3±3.0) vs (1.8±1.5) times/year, P<0.001] and a higher maximal body temperature [(38.2±0.9) vs (37.6±1.1) â, P=0.037]. Conclusions: The risk factors of laryngopharyngeal reflux disease in the aged included age ≤70 years, higher BMI, use of antipsychotic drugs and calcium channel blockers. The incidence of pneumonia in laryngopharyngeal reflux disease is higher, but the condition of pneumonia is milder.

Objective: To explore the characteristics of adverse drug reactions during the 24-week therapy with delamanid-containing regimen for patients with multidrug-resistant and rifampicin-resistant pulmonary tuberculosis (MDR/RR-PTB). Methods: The prospective multicenter study was conducted from June 2020 to June 2023. A total of 608 eligible patients with MDR/RR-PTB were enrolled in 26 tuberculosis medical institutions in China including 364 males and 79 females, aged 39.6(19.0-68.0) years. Patients were treated with chemotherapy regimens containing delamanid. Patients were closely supervised during treatment of medication, and all adverse reactions occurring during treatment were monitored and recorded. The clinical characteristics of adverse reactions were evaluated by descriptive analysis. Chi-square test and multivariate logistic regression were used to analyze the related factors of QTcF interval prolongation (QT corrected with Fridericia's formula). Results: Of the 608 patients enrolled in this study, 325 patients (53.5%) reported 710 adverse events within 24 weeks of treatment. The top 6 most common complications were hematological abnormalities (143 patients, 23.5%), QT prolongation (114 patients, 18.8%), liver toxicity (85 patients, 14.0%), gastrointestinal reaction (41 patients, 6.7%), peripheral neuropathy (25 patients, 4.1%) and mental disorders (21 patients, 3.5%). The prolongation of QT interval mostly occurred in the 12th week after the first dose of medication. Serious adverse reactions occurred in 21 patients (3.5%). There were 7 patients (1.2%) with mental disorders, including 2 patients (0.3%) with severe mental disorders. Conclusions: The safety of dalamanid-based regimen in the staged treatment of MDR/RR-PTB patients was generally good, and the incidence of adverse reactions was similar to that reported in foreign studies. This study found that the incidence of QT interval prolongation in Chinese patients was higher than that reported overseas, suggesting that the monitoring of electrocardiogram should be strengthened when using drugs containing delamanid that may cause QT interval prolongation.

Objective: To evaluate the efficacy and safety of glaucoma drainage implants(XEN-45 Gel Stent) for glaucoma treatment. Methods: A prospective study was conducted to continuously collect the clinical data of patients who were diagnosed with glaucoma and underwent XEN-45 Gel Stent implantation in the Ophthalmology Department of Peking University People's Hospital from January 2022 to August 2023. The visual acuity, intraocular pressure, number of glaucoma medications, and success rate of the patients were analyzed before and after surgery at 1 day, 1 week, 1 month, 3 months, 6 months, 12 months, and 18 months. The differences in intraocular pressure and number of glaucoma medications among primary open-angle glaucoma, primary angle closure glaucoma, secondary glaucoma, and different implantation methods of XEN-45 Gel Stent among patients with primary open-angle glaucoma were compared. The intraoperative and postoperative complications were observed, and the risk factors for needling and surgical complete success were analyzed. Results: A total of 48 eyes from 48 patients were included in this study, comprising 27 males and 21 females, with a mean age of (54.4±18.0) years and the disease duration was 36.0(7.3, 81.0) months.There were 28 cases of primary open-angle glaucoma, 4 cases of primary angle closure glaucoma, and 16 cases of secondary glaucoma.The follow-up period was 8.0 (3.0, 12.0) months. At 12 months after surgery, the intraocular pressure decreased from 20.5 (17.0, 26.0) mmHg to (13.5±3.3) mmHg (P<0.05), and the number of glaucoma medications decreased from 3.0 (3.0, 4.0) to 0.0 (0.0, 0.0) (P<0.05). The complete success rate and qualified success rate were 73.9% (17/23) and 91.3% (21/23), respectively. The most common postoperative complications were shallow anterior chamber in 6 cases (12.5%), hypotony in 3 cases (6.3%), and blocked stent in 3 cases (6.3%). The most common postoperative treatment was needling in 27 cases (56.3%). There was no significant difference in intraocular pressure among different types of glaucoma. In the comparison of postoperative effects of different surgical implantation methods for primary open-angle glaucoma, there were no statistically significant differences in intraocular pressure and the number of glaucoma medications at other follow-up time points except 1 month after surgery (P<0.05). Univariate logistic regression analysis did not find any risk factors associated with needling and surgical complete success. Conclusions: XEN-45 Gel Stent implantation is an effective and safe surgical option for different types of glaucoma patients in China, which can significantly reduce intraocular pressure and the use of glaucoma medications and has a high success rate. However, some patients may need needling or other treatments after surgery.

We present the results of a search for heavy QCD axions performed by the ArgoNeuT experiment at Fermilab. We search for heavy axions produced in the NuMI neutrino beam target and absorber decaying into dimuon pairs, which can be identified using the unique capabilities of ArgoNeuT and the MINOS near detector. This decay channel is motivated by a broad class of heavy QCD axion models that address the strong CP and axion quality problems with axion masses above the dimuon threshold. We obtain new constraints at a 95% confidence level for heavy axions in the previously unexplored mass range of 0.2-0.9 GeV, for axion decay constants around tens of TeV.

Objective: To investigate the levels of sex hormone and fertility in female patients after hematopoietic stem cell transplantation (HSCT), as well as their correlation with conditioning regimens, and analyse the effect of hormone replacement therapy (HRT) in young women after HSCT. Methods: Retrospective case series study. The clinical data of 147 women who underwent HSCT in the First Affiliated Hospital of Soochow University from January 2010 to January 2021 were retrospectively analyzed. The sex hormone levels were measured and followed-up, and the survival, menstrual fertility and the use of HRT of the patients were also followed-up. The sex hormone levels were measured after transplantation, and the ovarian function was evaluated. Independent sample t test and χ2 test were used for comparison between the two groups. Results: The median age of the 147 patients was 26 (range, 10-45) years. Of them, 135 patients received allogeneic HSCT and 12 patients received autologous HSCT. Furthermore, 129 patients received myeloablative conditioning, and 18 patients received reduced conditioning dose. The median follow-up time was 50 months (range, 18-134 months). Five patients died of disease recurrence during follow-up. Of the 54 patients with subcutaneous injection of zoladex, three recovered menstruation spontaneously after transplantation, and all of them were myeloablative conditioning patients, one patient gave birth to twins through assisted reproductive technology. Ninety-three patients did not use zoladex before conditioning, two patients with aplastic anemia with non-myeloablative transplantation resumed menstruation spontaneously, and conceived naturally. The level of follicle stimulating hormone after transplantation in patients receiving myeloablative conditioning regimen was significantly higher than that in patients receiving reduced-dose conditioning regimen [(95.28±3.94) U/L vs. (71.85±10.72) U/L, P=0.039]. Among 147 patients, 122 patients developed premature ovarian failure, 83 patients received sex hormone replacement therapy after transplantation, and 76 patients recovered menstruation and improved endocrine function. Conclusions: The incidence of premature ovarian failure is high in female patients after HSCT, and patients have a chance at natural conception. Reducing the dose of conditioning regimen and the application of zoladex before transplantation can reduce ovarian of conditioning drugs. HRT after transplantation can partially improve the endocrine function of patients.

Objective: To explore the changes of cerebral blood perfusion in patients with unilateral sudden sensorineural hearing loss (SSNHL) by using the three-dimensional pseudo-continuous arterial spin labeling (3D pCASL) technique. Methods: The clinical characteristics and ASL data of the 32 patients with unilateral SSNHL were retrospectively collected from November 2020 to June 2021 in Beijing Fuxing Hospital of Capital Medical University, among them, there were 7 males and 25 females, aged from 17 to 73 (44.9±14.4) years. According to the location of SSNHL, they were divided into the left SSNHL (L-SSNHL) group (18 cases) and the right SSNHL (R-SSNHL) group (14 cases). A total of 34 healthy volunteers, which including 14 males and 20 females, aged from 24 to 68 (46.2±14.4) years were enrolled from the local community. The parameter of cerebral blood flow (CBF) of each brain area was obtained using the CereFlow software. The Brainnetome Atlas software package based on MATLAB was used for visualization. The independent-samples t test was conducted to compare the difference of cerebral blood perfusion between the unilateral SSNHL group and healthy control (HC) group. Pearson correlation analysis was used to evaluate the correlation between changes in cerebral blood perfusion and clinical scale scores. Results: The CBF of left orbital gyrus part 5, left inferior temporal gyrus part 7, right orbital gyrus part 5, right inferior temporal gyrus part 1, right inferior temporal gyrus part 7, and right parahippocampal gyrus part 3 of the L-SSNHL group were higher than that in the HC group[(49.1±8.8) vs (31.6±10.9)ml·100g-1·min-1;(42.8±14.3) vs (27.1±13.6)ml·100g-1·min-1;(51.8±9.4) vs (27.2±11.2)ml·100g-1·min-1;(38.8±5.7) vs (28.0±9.2)ml·100g-1·min-1;(38.4±13.8) vs (23.6±10.3)ml·100g-1·min-1;(42.4±9.4) vs (30.1±12.6)ml·100g-1·min-1; all P<0.05]. The CBF of left superior frontal gyrus part 7 and left middle frontal gyrus part 3 of the L-SSNHL group were lower than that in the HC group[(48.2±7.9) vs (59.3±13.7)ml·100g-1·min-1;(46.4±10.3) vs (59.3±16.9)ml·100g-1·min-1;all P<0.05]. The CBF of left orbital gyrus part 5, right orbital gyrus part 5, right inferior temporal gyrus part 1, and right inferior temporal gyrus part 7 of the R-SSNHL group were higher than that in the HC group[(50.6±7.0) vs (31.6±10.9)ml·100g-1·min-1;(50.9±8.8) vs (27.2±11.2)ml·100 g-1·min-1;(38.0±7.2) vs (28.0±9.2)ml·100g-1·min-1;(35.7±8.5) vs (23.6±10.3)ml·100g-1·min-1;all P<0.05]; the CBF of right insular part 4 was lower than that in the HC group [(44.2±6.1) vs (54.4±11.3) ml·100 g-1·min-1, P=0.018]. In the L-SSNHL group, the CBF of left superior frontal gyrus part 7 and right orbital gyrus part 5 were negatively correlated with the VAS score(r=-0.83, -0.81, all P<0.05), and the CBF of right orbital gyrus part 5 was negatively correlated with the THI score(r=-0.75, P=0.013). There was no statistically significant correlation between the remaining differences in brain regions and clinical scale scores(all P>0.05). Conclusion: Changes in cerebral blood perfusion in multiple brain regions were found in patients with unilateral SSNHL by using the 3D pCASL technique.

Objective: To analyze the mediating effect of work-occupation fit between occupational stress and anxiety symptoms in medical staff. Methods: Convenience sampling method was adopted to select participants of one general hospital and three specialized hospitals as respondents for a questionnaire survey in Henan Province from October 2020 to January 2021. A total of 2050 medical staff were investigated, and 1988 valid questionnaires were collected, and the effective rate of the questionnaire was 97.0% (1988/2050) . The "Depression-Anxiety-Stress Scale" and "Worker-Occupation Fit Inventory" were used to evaluate the occupational stress, anxiety symptoms and worker-occupation fit level of medical staff, and the mediation effect of work-occupation fit on the relationship between occupational stress and anxiety symptoms was analyzed using a mediating effect model. Results: The average age of the 1988 medical staff was (32.7±7.8) years old, the positive detection rates of occupational stress and anxiety symptoms were 42.5% (845/1988) and 56.7% (1127/1988) , respectively. Anxiety symptoms of medical staff were positively correlated with occupational stress, negatively correlated with worker-occupation fit (r=0.831, -0.364, P<0.001) , work-occupation fit was negatively correlated with occupational stress (r=-0.259, P<0.001) . The results of the mediation effect analysis showed that occupational stress had a direct effect on anxiety symptoms (ß=0.677, BCa 95%CI: 0.648-0.707) , and worker-occupation fit (ß=0.047, BCa 95%CI: 0.039-0.056) , characteristic fit (ß=0.089, BCa 95%CI: 0.074-0.104) , need-supply fit (ß=0.075, BCa 95%CI: 0.062-0.089) , and ability-demand fit (ß=0.035, BCa 95%CI: 0.026-0.044) mediated the association between occupational stress and anxiety symptoms in medical staff, with the mediating effect as a percentage of 6.5%, 12.3%, 10.3%, and 4.8%, respectively. Conclusion: Worker-occupation fit has a mediating effect between occupational stress and anxiety symptoms in medical staff, but mainly direct effect.

Objective: To explore the clinical application value of MRI-PDFF on different liver segments for the evaluation of non-alcoholic fatty liver disease (NAFLD). Methods: 178 volunteers from March 2019 to February 2020 were included. PDFF values ââof all nine segments of the liver were measured using CSE3.0T MRI scan. The obtained average value was used to represent the average liver fat content. PDFF values of each or combined liver segment were equally compared with the average value to observe the representativeness of fat content. Receiver operating characteristic curve was used to analyze the diagnostic performance of each liver segment, and the Youden index was used to calculate the cutoff value. Paired-sample t-test or non-parametric Kruskal-Wallis test were used to compare measurement data among groups. Results: 178 volunteers average liver fat content ranged from 0.89% to 42.61% with MRI-PDFF, and 71.35% (127/178) of the volunteers had PDFF > 5%. There was no significant difference between SIII, SIVb, SV, and SVIII liver segments when compared with the average value (P > 0.05). PDFF values ââof SI, SII, and SIV a liver segments were all lower than the average value, while the PDFF values ââof SVI and SVII liver segments were all higher than the average value (P ââ< 0.05). MRI-PDFF sensitivity value for diagnosing liver steatosis of nine liver segments was 85.8% ~ 94.5%, and the specificity was higher than 96.0%. Among them, the SV liver segment had the highest sensitivity (94.5%), and the corresponding optimal diagnostic threshold value was 5.13%. Compared with single and combined liver segment, the PDFF value of SII, SV, SVI combined liver segment had the highest diagnostic performance for fatty liver, with the sensitivity and specificity of 96.9%, and 100%, respectively, and the corresponding optimal diagnostic threshold value was 5.17%. Conclusion: Compared with single and other combined liver segments, MRI-PDFF values of SII, SV, and SVI combined liver segments have higher sensitivity and specificity for the diagnosis of NAFLD, and it can be used as the first choice for the determination of liver fat content with MRI.

Objective: To study the current development of thoracic surgery in China. Methods: Chinese Society for Thoracic and Cardiovascular Surgery and Chinese Association for Thoracic Surgeons jointly conducted a network survey to directors of thoracic surgery departments in the tertiary hospitals in China from November to December 2018. The contents of the survey included the basic information of the hospital and the status of thoracic surgery department in the hospital. Rank sum test was used to compare the data between different regional hospitals Results: A total of 636 tertiary hospitals participated in the survey. The total number of beds for thoracic surgery departments was 30 646, with M(Q(R)) of 40(20) (range: 3 to 393) for each hospital. The total number of thoracic surgeons was 6 747, with M(Q(R)) of 9(6) (range: 1 to 75) in each hospital. In 2015, a total of 312 425 operations were performed in the 636 hospitals, with M(Q(R)) of 268(484.5) (range: 4 to 8 320) for each hospital. The total number of lung cancer surgeries was 146 601 in 2015, with M(Q(R)) of 100(216) (range: 0 to 6 911) operations in each hospital. The total number of esophageal cancer operations was 67 076, with M(Q(R)) of 40(95) (range: 0 to 1 550) in each hospital. Minimal invasive thoracic surgery was performed in 94.3% (601/636) of the hospitals, with 86.6% (551/636) of hospitals carried out video-assisted thoracoscopic (VATS) lobectomy. Among the hospitals performing VATS lobectomy, 89.3% (492/551) of them started to perform the technique after 2006, and 93.1% (513/551) of them do single-direction thoracoscopic lobectomy. A total of 403 640 VATS lobectomies had been performed until 2015, including 163 682 cases of single-direction thoracoscopic lobectomy. In 2015, 73.74% (108 116/146 601) lung cancer operations and 37.44% (25 110/67 076) of esophageal cancer resections were performed by minimally invasive technique. The development level of hospitals among eastern, middle and Western China was different significantly on number of doctors, number of total operations, number of lung cancer surgeries, proportion of minimally invasive lung cancer surgery, number of esophageal cancer surgeries, and proportion of minimally invasive esophageal cancer surgery (χ(2)â¶7.65 to 60.8, all P<0.05). Conclusions: The discipline of thoracic surgery, especially the minimally invasive thoracic surgery in China is now experiencing a rapid development. The proportion of minimally invasive lung cancer surgery is higher than that of in the developed countries. However, unbalanced development among different regions is still a great challenge in China.

Immune homeostasis is a steady immune state that not only protects the host from pathogens but also prevents the emergence of pathological self-reactive immune cells. The disruption of immune homeostasis leads to the development of various diseases, such as cancer and autoimmune diseases. An emerging paradigm for the treatment of these diseases with dysfunctional immune systems is the restoration and maintenance of immune homeostasis. However, currently available drugs exert a unidirectional influence on immunity whereby they either augment or inhibit it. This strategy is associated with the drawback of potential adverse effects arising from uncontrolled activation or suppression of the immune system. Fortunately, evidence suggests that acupuncture can bidirectionally regulate the immune system to maintain immune homeostasis. In cases of immunosuppressive diseases (e.g. cancer), acupuncture has an enhancing effect on immunity. Conversely, in autoimmune diseases (e.g. rheumatoid arthritis), acupuncture has been observed to have an immunosuppressive effect, which helps restore normal immune tolerance. However, there is no publication systematically summarizing the bidirectional regulatory effects of acupuncture on the immune system in the literature. Here, our review provides a comprehensive overview of the various mechanisms through which acupuncture modulates the immune system in a bidirectional manner. These mechanisms include the augmentation of NK and CD8+ T cell function, as well as the restoration of Th1/Th2, Th17/Treg and M1/M2 balance. Thus, we propose the concept that acupuncture has the potential to alleviate illnesses through the facilitation of immune normalization. Moreover, we further highlight the therapeutic potential of acupuncture.

Objective: To analyze and compare the efficacy and safety of pingyangmycin fibrin glue composite (PFG) and pingyangmycin dexamethasone composite (PD) in the treatment of pharyngolaryngeal venous malformation (VM). Methods: The clinical data of 98 patients with pharyngolaryngeal VM who underwent sclerotherapy with pingyangmycin composite in the First Affiliated Hospital of Sun Yat-sen University from June 2013 to November 2022 were retrospectively analyzed. According to their treatment, patients were divided into PFG group (n=34) and PD group (n=64), among those patients there were 54 males and 44 females, aged 1-77(37.06±18.86)years. The lesion size, total treatment times and adverse events were recorded before and after treatment. And the efficacy was divided into three grades: recovery, effective and invalid. According to the length of VM, all patients were divided into three subgroups, to compare the differences in efficacy and treatment times between each two groups.And finally the adverse events and their treatments were analyzed. SPSS 25.0 software was used for statistical analysis. Results: The efficacy of PFG group was 94.11%(32/34), the recovery rate was 85.29%(29/34).And the efficacy of PD group was 93.75%(60/64), the recovery rate was 64.06%(41/64). No serious adverse eventst occurred in subgroup comparison, there was no statistical difference between the two groups in efficacy and the times of treatments when the length was≤3 cm (Zefficacy=1.04, ttreatment times=2.18, P>0.05); when the length was 3-5 cm, there was no significant efficacy difference between the two groups(Zefficacy=1.17, P>0.05), but the treatment times of PFG were less (ttreatment times=4.87, P<0.01); when the length≥5 cm, efficacy of PFG was significantly better than PD (Zefficacy=2.94, P<0.01), and had fewer treatments times (ttreatment times=2.16, P<0.01). There were no serious adverse events in either group during treatment and follow-up. Conclusion: Both PFG and PD are safe and effective composite sclerotherapy agent for the treatment of laryngeal VM, but PFG has a higher cure rate and fewer treatment times for massive lesions.

The incidence and clinical manifestations of scars and keloids are different in different races, and Asians are more likely to suffer from this disease than Caucasians. China and Japan are the representative countries for medical development in Asia. There is no comprehensive study on the similarities and differences between the academic circles in the two countries in the diagnosis and treatment of scars and keloids. By comparing and analyzing the latest expert consensus in the field of scars and keloids between the two countries, we found that the organization form of expert team and main contents of the consensus from the two countries are basically similar. However, there are obvious differences in the composition of experts, logical thinking and organizational form of consensus contents, and details of the specific schemes for scar assessment, diagnosis, and treatment. The differences in the diagnosis and treatment of scars and keloids in China and Japan may indicate the direction of future cooperative research.

Scars are the result of abnormal repair of skin tissue trauma. Recently, fractional laser is more and more widely used in the treatment of scars, but its mechanism is not clear. Studies have shown that fractional laser could produce multiple microthermal zones in target skin, induce wound repair responses, affect the function of epidermal and dermal cells, induce changes in blood vessels and collagens, and change the expression of heat shock proteins, microRNA, matrix metalloproteinases, cytokines such as transforming growth factor ß, basic fibroblast growth factor, and facilitate drug delivery, thus achieving the effect of treating scars. This article reviews the mechanism of fractional laser in treating scars from three aspects, including the tissue and cell mechanism, molecular mechanism, and drug delivery.

Objective: To investigate the survival and prognosis of B-lineage acute lymphoblastic leukemia (B-ALL) patients with TP53 mutation. Methods: The clinical data of 479 newly diagnosed B-ALL patients treated in the First Affiliated Hospital of Soochow University from January 2016 to December 2019 were retrospectively analyzed. Results: Among 479 B-ALL patients, 34 cases (7.1%) were positive for TP53 gene mutation, and a total of 36 TP53 mutations were detected, including 10 frameshift gene mutations (27.8%) , 23 missense mutations (63.9%) and 3 nonsense mutations (8.3%) . A total of 34 (94.4%) mutations were located in the DNA binding domain (exons 5-8) .The average number of mutated genes in patients with TP53 gene mutation (2.3) and the group without TP53 gene mutation (1.1) were statistically different (P<0.001) . The proportion of Ph positive and Ph-like positive patients in the TP53 gene mutation negative group was significantly higher than that of the TP53 mutation positive group, and the difference was statistically significant (P<0.001) . The 3-year OS and EFS rates of the TP53 gene mutation negative group were significantly higher than those of the TP53 gene mutation positive group. The differences in OS and EFS rates between the two groups were statistically significant (χ(2)= 4.694, P = 0.030; χ(2)= 5.080, P= 0.024) . In the multivariate analysis, failure to achieve remission (CR) after one course of induction chemotherapy was an independent adverse prognostic factor affecting OS.Of the 34 patients with TP53 mutation, 16 underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the CR(1) state, and 2 patients with recurrence after transplantation obtained CR(2) after infusion of donor-derived anti-CD19 chimeric antigen receptor T (CAR-T) cells. Among the 11 patients with TP53 gene mutation who relapsed during consolidation chemotherapy, 6 received anti-CD19 CAR T cell therapy, 4 patients achieved remission and minimal residual disease (MRD) turned negative, followed by bridging allo-HSCT, and 2 of them sustained CR. Conclusion: Missense mutations are the most common in B-ALL patients with TP53 gene mutation, and the majority of mutations were located in the DNA binding domain. B-ALL patients with TP53 gene mutation should undergo allo-HSCT as soon as possible after CAR-T cell therapy has cleared the MRD after recurrence. B-ALL patients with TP53 gene mutation still have a higher recurrence rate after allo-HSCT, and the infusion of donor-derived CAR-T cells can achieve better sustained remission.

Objective: To analyze the efficiency and safety of navigation guided extraction of impacted supernumerary tooth. Methods: Twenty-five cases of navigation guided supernumerary tooth extraction and 25 cases of non-navigation guided supernumerary tooth extraction (control group) were included in the study. Each group had 3 cases with one impacted supernumerary tooth and 22 cases with two impacted teeth. Results: Preoperative navigation system designing time was (45.0±8.0) min in average. Navigation system installation time was (15.0±2.8) min. The average operation time was (0.64±0.08) hour in navigation group and (0.91±0.09) hour in control group. Conclusions: Navigation guided extraction of impacted supernumerary tooth takes less time for operation but more time for the preoperative navigation system design.

Objective: To build risk prediction models for acute kidney injury (AKI) in severely burned patients, and to compare the prediction performance of machine learning method and logistic regression model. Methods: The clinical data of 157 severely burned patients in August 2nd Kunshan factory aluminum dust explosion accident conforming to the inclusion criteria were collected. Patients suffering AKI within 90 days after admission were enrolled in group AKI, while the others were enrolled in non-AKI group. Single factor analysis was used to choose independent factors associated with AKI, including sex, age, admission time, features of basic injuries, initial score on admission, treatment condition, and mortality on post injury days 30, 60, and 90. Data were processed with Mann-Whitney U test, chi-square test, and Fisher's exact test. Variables with P<0.1 in single factor analysis and those with possible clinical significance were brought into the establishment of prediction model. Logistic regression and XGBoost machine learning algorithm were used to build the prediction model of AKI. The area under receiver operating characteristic curve (AUC) was calculated, and the sensitivity and specificity for optimal threshold value were also calculated for each model. Nonparametric resampling test was used to compare the significance of difference of AUC of the two models. Results: (1) Eighty-nine (56.7%) patients developed AKI within 90 days from admission. Compared with 68 patients in non-AKI group, 89 patients in group AKI were older (Z=-2.203, P<0.05), with larger total burn area and full-thickness burn area (Z=-5.200, -6.297, P<0.01), worse acute physical and chronic health evaluation (APACHE) â ¡ score, abbreviated burn severity index score, and sequential organ failure assessment (SOFA) score on admission (Z=-7.485, -4.739, -4.590, P<0.01), higher occurrence rate of sepsis (χ(2)=33.087, P<0.01), higher rates of accepting tracheotomy, mechanical ventilation, and continuous renal replacement therapy (χ(2)=12.373, 17.201, 43.763, P<0.01), larger first excision area (Z=-2.191, P<0.05), and higher mortality on post injury days 30, 60, and 90 (χ(2)=7.483, 37.259, 45.533, P<0.01). There were no statistically significant differences in sex, open decompression, admission time, 24-hour fluid volume after admission, 48-hour fluid volume after admission, the first 24-hour urine volume, the second 24 hour urine volume, the first excision time, and inhalation injury (χ(2)=0.529, 3.318, Z=-1.746, -0.016, -1.199, -1.824, -0.625, -1.747, P>0.05). The rates of deep vein catheterization of patients in the two groups were both 100%. (2) There were twenty possible prediction variables for preliminary establishment of model according to the difference results of single factor analysis and clinical significance of variables. (3) The logistic regression prediction model had three variables: APACHE â ¡ score [odds ratio (OR)=1.36, 95% confidence interval (CI)=1.20-1.53, P<0.001], sepsis (OR=2.63, 95% CI=0.90-7.66, P>0.05), and the first 24-hour urine volume (OR=0.71, 95% CI=0.50-1.01, P>0.05). The AUC of the logistic regression prediction model was 0.875 (95% CI=0.821-0.930), with the specificity and sensitivity of optimal threshold value 84.4% and 77.7%, respectively. (4) XGBoost machine learning model had seven main predictive variables: APACHE â ¡ score, full-thickness burn area, 24-hour fluid volume after admission, sepsis, the first 24-hour urine volume, SOFA score, and 48-hour fluid volume after admission. The AUC of machine learning model was 0.920 (95% CI=0.879-0.962), higher than that of logistic regression model (P<0.001), with the specificity and sensitivity of optimal threshold value 89.7% and 82.0%, respectively. Conclusions: Sepsis and fluid resuscitation are two important predictive variables that can be intervened for AKI in severely burned patients. Machine learning method has a better performance and can provide more accurate prediction for individuals than logistic regression prediction model, and therefore has good clinical application prospect.

A 35-year-old Taiwanese woman visited us for prenatal evaluation in the 20th week of pregnancy. Both clinical observation of the mother and analysis of maternal DNA indicated a diagnosis of Apert syndrome. Sonographic examination of the fetus demonstrated findings that were consistent with this diagnosis; however, no prematurely fused cranial sutures were observed. The pregnancy was terminated after genetic counselling and fetal DNA analysis showed the same mutation as found in the mother. Autopsy of the abortus revealed the same findings as were detected by sonography; however, all cranial sutures were widely separated. These findings indicate that, in Apert syndrome, craniosynostosis and syndactyly may develop asynchronously up to 20 weeks of pregnancy.
