ObjectiveTo assess the value of apparent diffusion coefficient （ADC） in the treatment of uterine fibroid using magnetic resonance guided focused ultrasound surgery （MRgFUS）. MethodsThe MRI and clinical data of 56 patients with uterine fibroid before， at 3 and 6 months after MRgFUS treatment， at Foshan Hospital of Traditional Chinese Medicine from December 2018 to October 2022， were retrospectively analyzed. The correlation between the ADC value and lesion volume， symptoms severity score （SSS） and uterine fibroid symptoms quality of life questionnaire （UFS-QOL） were analyzed. ANOVA was used to compare the differences in related parameters before and after treatment， and Pearson’s method was performed to analyze data correlation. ResultsThere were significant differences in ADC value ［（1.11±0.13）， （1.84±0.09）， （2.12±0.24），×10^-3/（mm²/s）］， lesion volume （102±35.30， 56.70±18.88， 46.93±18.99，cm³）， SSS （36.73±11.74， 21.77±10.21， 17.66±9.30） and UFS-QOL score （59.05±17.48， 76.54±16.50， 82.46±12.37） between before treatment and each time point after treatment （F value was 557.837， 73.589， 53.976 and 37.606， respectively， all P<0.05）. The ADC values were negatively correlated with lesion volume and SSS， and positively correlated with UFS-QOL score， with correlation coefficients of -0.586， -0.630 and 0.592， respectively （all P<0.05）. ConclusionThe ADC value has clinical significance for the treatment of uterine fibroid using MRgFUS.

Chronic stress leads to many psychiatric disorders, including social and anxiety disorders that are associated with over-activation of neurons in the basolateral amygdala (BLA). However, not all individuals develop psychiatric diseases, many showing considerable resilience against stress exposure. Whether BLA neuronal activity is involved in regulating an individual's vulnerability to stress remains elusive. In this study, using a mouse model of chronic social defeat stress (CSDS), we divided the mice into susceptible and resilient subgroups based on their social interaction behavior. Using in vivo fiber photometry and in vitro patch-clamp recording, we showed that CSDS persistently (after 20 days of recovery from stress) increased BLA neuronal activity in all the mice regardless of their susceptible or resilient nature, although impaired social interaction behavior was only observed in susceptible mice. Increased anxiety-like behavior, on the other hand, was evident in both groups. Notably, the CSDS-induced increase of BLA neuronal activity correlated well with the heightened anxiety-like but not the social avoidance behavior in mice. These findings provide new insight to our understanding of the role of neuronal activity in the amygdala in mediating stress-related psychiatric disorders.

ObjectiveTo investigate the effect and mechanism of total flavones of Spatholobi Caulis （TFSC） against depression in rats. MethodThe fifty KM mice were randomly divided into the normal group and high-， medium-， and low-dose （1， 0.5， 0.25 g·kg^-1） TFSC groups and gavaged with the corresponding drugs for 12 successive days. One hour after the last administration， the immobility time in forced swimming test and tail suspension test was recorded. The SD rats were randomly divided into the normal group， model group， fluoxetine （5 mg·kg^-1） group， and high- and low-dose （1， 0.25 g·kg^-1） TFSC groups. Following the exposure of rats to two different kinds of stimuli daily for inducing chronic unpredictable stress， they were administered with the corresponding drugs for 21 d. After the experiment， the levels of serum neurotransmitters and inflammatory factors in rats were detected by enzyme-linked immunosorbent assay （ELISA）. The changes in hippocampal neurons of rats were observed by hematoxylin-eosin （HE） and Nissl staining. The mRNA expression levels of nuclear factor-κB （NF-κB） and tumor necrosis factor-α （TNF-α） in the hippocampus of rats were detected by real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）， and the protein expression levels of cAMP-response element binding protein （CREB）， phosphorylated CREB （p-CREB）， and brain-derived neurotrophic factor （BDNF） in hippocampal tissues by Western blot. ResultCompared with the normal group， TFSC significantly shortened the immobility time of mice in tail suspension and swimming tests （P<0.05）. Compared with the normal group， the model group exhibited reduced sucrose intake and wilderness activity （P<0.01）， decreased 5-HT， DA， NE （P<0.05， P<0.01）， MAO， IL-6， TNF-α （P<0.05， P<0.01）， damaged neurons， increased mRNA levels of TNF-α and NF-κB （P<0.01）， and down-regulated BDNF and CREB protein expression （P<0.05）. Compared with the model group， TFSC significantly enhanced sucrose intake and wilderness activity of rats （P<0.05）， increased the serum 5-HT， DA and NE （P<0.05， P<0.01）， and decreased the serum MAO， IL-6， and TNF-α （P<0.05， P<0.01） as well as NF-κB and TNF-α mRNA expression （P<0.01）， up-regulated the protein expression levels of BDNF and CREB （P<0.01）， and improved the pathological symptoms of hippocampus. ConclusionTFSC improved the hippocampal neurons of rats via CREB/BDNF signaling pathway and reduced depressive pathological damage， thus relieving depression.

Objective Coronavirus disease 2019 (COVID-19) and tuberculosis (TB) are major public health and social issues worldwide. The long-term follow-up of COVID-19 with pulmonary TB (PTB) survivors after discharge is unclear. This study aimed to comprehensively describe clinical outcomes, including sequela and recurrence at 3, 12, and 24 months after discharge, among COVID-19 with PTB survivors. Methods From January 22, 2020 to May 6, 2022, with a follow-up by August 26, 2022, a prospective, multicenter follow-up study was conducted on COVID-19 with PTB survivors after discharge in 13hospitals from four provinces in China. Clinical outcomes, including sequela, recurrence of COVID-19, and PTB survivors, were collected via telephone and face-to-face interviews at 3, 12, and 24 months after discharge. Results Thirty-two COVID-19 with PTB survivors were included. The median age was 52 (45, 59) years, and 23 (71.9％) were men. Among them, nearly two-thirds (62.5％) of the survivors were moderate, three (9.4％) were severe, and more than half (59.4％) had at least one comorbidity (PTB excluded). The proportion of COVID-19 survivors with at least one sequela symptom decreased from 40.6％ at 3 months to 15.8％ at 24 months, with anxiety having a higher proportion over a follow-up. Cough and amnesia recovered at the 12-month follow-up, while anxiety, fatigue, and trouble sleeping remained after 24 months. Additionally, one (3.1％) case presented two recurrences of PTB and no re-positive COVID-19 during the follow-up period. Conclusion The proportion of long symptoms in COVID-19 with PTB survivors decreased over time, while nearly one in six still experience persistent symptoms with a higher proportion of anxiety. The recurrence of PTB and the psychological support of COVID-19 with PTB after discharge require more attention.

Objective: To investigate the feasibility and safety of auricle reconstruction combined with Bonebridge implantation for bilateral aural atresia patients. Methods: A retrospective analysis was conducted for 36 cases(72 ears) who underwent Bonebridge implantation combined with bilateral auricle reconstruction from February 1, 2017 to January 15, 2020. All cases were bilateral congenital aural atresia and underwent Nagata auricle reconstruction for both sides simultaneously. Bonebridge implantations were performed during the second stage of auricle reconstruction. Results: All 36 patients healed well and had no surgical complications when discharged. The preoperative average bone conduction threshold of the patients was(8.5±5.8) dB HL and postoperative bone conduction threshold was (8.4±5.2) dB HL. There was no significant change after the implantation (P=0.724). The preoperative average air conduction threshold of was(64.9±7.4)dB HL and postoperative air conduction threshold was (24.0±5.3) dB HL, which had a significant change after the implantation (P<0.001). The hearing threshold with Bonebridge significantly decreased by 40.9 dB HL compared with the preoperative air conduction threshold(P<0.001). The speech recognition rate of monosyllable words, disyllabic words and short sentences in quiet environment increased by 62.5%, 63.5% and 72.2% respectively. The differences were statistically significant (P<0.001). The speech recognition rate of monosyllabic words, disyllabic words and short sentences in noise environment were significantly increased by 55.9%, 58.9% and 69.9% respectively (P<0.001). After a follow-up of 18.3 months in average, the hearing results were stable and the aesthetic outcomes were satisfied. One patient had implant rupture and healed after revision surgery. Conclusions: With an integrated surgical procedure, patients with bilateral congenital aural atresia can complete bilateral auricle reconstruction and hearing implantation within six months. This integrated surgical procedure is safe and efficient, with a stable hearing improvement and good appearance.

Objective: To observe the incidence and treatment of radiation rectal injury complicated with anxiety, depression and somatic symptom disorder. Methods: A cross-sectional survey research method was carried out. Patients with radiation rectal injury managed by members of the editorial board of Chinese Journal of Gastrointestinal Surgery were the subjects of investigation. The inclusion criteria of the survey subjects: (1) patients suffered from pelvic tumors and received pelvic radiotherapy; (2) colonoscopy showed inflammatory reaction or ulcer in the rectum. Exclusion criteria: (1) patient had a history of psycho-somatic disease before radiotherapy; (2) patient was unable to use a smart phone, unable to read and understand the questions in the questionnaire displayed on the phone; (3) patient refused to sign an informed consent form. According to the SOMA self-rating scale, PHQ-15 self-rating scale, GAD-7 and PHQ-9 self-rating scale, the electronic questionnaire of "Psychological Survey of Radiation Proctitis" was designed. The questionnaire was sent to patients with radiation rectal injury managed by the committee through the WeChat group. Observational indicators: (1) radiation rectal injury symptom assessment: using SOMA self-rating scale, radiation rectal injury symptom classification: mild group (≤3 points), moderate group (4-6 points) and severe group (> 6 points); (2) incidence of anxiety, depression and physical disorder: using GAD-7, PHQ-9 and PHQ-15 self-rating scales respectively for assessment; (3) correlation of radiation rectal injury symptom grading with anxiety, depression, and somatic symptom disorder. Results: Seventy-one qualified questionnaires were collected, of which 41 (56.9%) were from Guangzhou. Among the 71 patients, 6 were males and 65 were females; the mean age was (55.7±9.3) years old and 48 patients (67.6%) were less than 60 years old; the median confirmed duration of radiation rectal injury was 2.0 (1.0, 5.0) years. (1) Evaluation of symptoms of radiation rectal injury: 18 cases of mild (25.4%), 27 cases of moderate (38.0%), and 26 cases of severe (36.6%). (2) Incidence of anxiety, depression and somatic disorder: 12 patients (16.9%) without comorbidities; 59 patients (83.1%) with anxiety, depression, or somatic disorder, of whom 2 patients only had anxiety, 1 patient only had depression, 9 only had somatic disorder, 2 had anxiety plus depression, 4 had anxiety plus somatic disorder, 2 had depression plus somatic disorder, and 40 had all three symptoms. (3) correlation of radiation rectal injury grading with anxiety, depression, and somatic symptom disorder: as compared to patients in mild group and moderate group, those in severe group had higher severity of anxiety and somatic symptom disorder (Z=-2.143, P=0.032; Z=-2.045, P=0.041), while there was no statistically significant difference of depression between mild group and moderate group (Z=-1.176, P=0.240). Pearson correlation analysis revealed that radiation rectal injury symptom score was positively correlated with anxiety (r=0.300, P=0.013), depression (r=0.287, P=0.015) and somatic symptom disorder (r=0.344, P=0.003). Conclusions: The incidence of anxiety, depression, and somatic symptom disorder in patients with radiation rectal injury is extremely high. It is necessary to strengthen the diagnosis and treatment of somatic symptom disorder, so as to alleviate the symptoms of patients with pelvic perineum pain and improve the quality of life.

Objective:To investigate the effects and mechanism of Gecko extract for treatment of depression in rats. Method:The depression rats were induced by intraperitoneal injection of reserpine （0.5 mg·kg^-1）. The successfully modeled rats were randomly divided into model group， fluoxetine group （1.8 mg·kg^-1）， high dose and low dose groups of Gecko extract （12， 6 g·kg^-1）. The rats were given corresponding dose of drugs once a day for 10 days. After administration， the levels of neurotransmitters and inflammatory factors in serum and prefrontal cortex of rats were detected by enzyme-linked immunosorbent assay （ELISA）. The cell changes in hippocampal tissues were observed by hematoxylin-eosin （HE） staining. The mRNA levels of interleukin-6 （IL-6）， nuclear factor-κB （NF-κB）， and tumor necrosis factor （TNF-α） in the hippocampus of rats were detected by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. The protein levels of Toll-like receptor 4 （TLR4） and NF-κB in hippocampal tissues of rats were detected by Western blot. Result:Compared with the normal group， Gecko extract significantly shortened the immobility time of tail suspension and swimming in mice. Compared with model group， Gecko extract significantly reduced blepharoptosis and retention time in circles for the rats （P<0.05）， increased the levels of 5-hydroxytryptamine （5-HT） and dopamine （DA） in serum （P<0.05）， decreased the levels of Monoamine oxidase （MAO）， IL-6， and TNF-α in serum （P<0.05） and prefrontal cortex （P<0.05）， decreased the mRNA levels of inflammatory cytokines IL-6， NF-κB and TNF-α and the protein expressions of TLR4 and NF-κB in the hippocampus of rats （P<0.05， P<0.01）， and improved the pathological symptoms of the hippocampus. Conclusion:Gecko extract can significantly alleviate the pathological damage of depression and improve the symptoms of depression， and its mechanism may be due to inhibiting TLR4/NF-κB signaling pathway and reducing the expression of NF-κB， IL-6 and other inflammatory factors in the hippocampus of rats.

Objective:To establish autoverification rules for coagulation tests in multicenter cooperative units, in order to reduce workload for manual review of suspected results and shorten turnaround time (TAT) of test reports, while ensure the accuracy of results.Methods:A total of 14 394 blood samples were collected from fourteen hospitals during December 2019 to March 2020. These samples included: Rules Establishment Group 11 230 cases, including 1 182 cases for Delta check rules; Rules Validation Group 3 164 cases, including 487cases for Delta check; Clinical Application Trial Group 77 269 cases. Samples were analyzed for coagulation tests using Sysmex CS series automatic coagulation analyzers, and the clinical information, instrument parameters, test results, clinical diagnosis, medication history of anticoagulant and other relative results such as HCT, TG, TBIL, DBIL were summarized; on the basis of historical data, the 2.5 and 97.5 percentile of all data arranged from low to high were initially accumulated; on the basis of clinical suggestions, critical values and specific drug use as well as relative guidelines, autoverification rules and limits were established.The rules were then input into middleware, in which Stage I/Stage II validation was done. Positive coincidence, negative coincidence, false negative, false positive, autoverification pass rate, passing accuracy (coincidence of autoverification and manual verification) were calculated. Autoverification rules underwent trial application in coagulation results reports.Results:(1) The autoverification algorisms involve 33 rules regarding PT/INR, APTT, FBG, D-dimer, FDP,Delta check, reaction curve and sample abnormalities; (2)Autoverification Establishment Group showed autoverification pass rate was 68.42% (7 684/11 230), the false negative rate was 0%(0/11230), coincidence of autoverification and manual verification was 98.51%(11 063/11 230), in which positive coincidence and negative coincidence were respectively 30.09% (3 379/11 230) and 68.42%(7 684/11 230); Autoverification Validation Group showed autoverification pass rate was 60.37%(1 910/3 164), the false negative rate was 0%(0/11 230), coincidence of autoverification and manual verification was 97.79%(3 094/3 164), in which positive coincidence and negative coincidence were respectively 37.42%(1 184/3 164) and 60.37%(1 910/3 164); (3) Trialed implementation of these autoverification rules on 77 269 coagulation samples showed that the average TAT shortened by 8.5 min-83.1 min.Conclusions:This study established 33 autoverification rules in coagulation tests. Validation showedthese rules could ensure test quality while shortening TAT and lighten manual workload.

Objective: Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear. Methods: A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients' medical records. Multivariable logistic regression models were used to estimate the odds ratio ( Results: Overall, 158 (13.6%) patients were diagnosed with severe illness and 32 (2.7%) had unfavorable outcomes. Hypertension (2.87, 1.30-6.32), type 2 diabetes (T2DM) (3.57, 2.32-5.49), cardiovascular disease (CVD) (3.78, 1.81-7.89), fatty liver disease (7.53, 1.96-28.96), hyperlipidemia (2.15, 1.26-3.67), other lung diseases (6.00, 3.01-11.96), and electrolyte imbalance (10.40, 3.00-26.10) were independently linked to increased odds of being severely ill. T2DM (6.07, 2.89-12.75), CVD (8.47, 6.03-11.89), and electrolyte imbalance (19.44, 11.47-32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission (5.46, 3.25-9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes (6.58, 1.46-29.64) within two weeks. Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.
