To summarise the clinical experience of treating insomnia with the method of resolving depression， regulating the middle， and tranquilising mind. It is believed that the key to the pathogenesis of insomnia lies in qi depression， disharmony of qi pivot， and disharmony of qi and blood， and the core treatment is to resolve depression， regulating the middle， and tranquilising mind. The self-prescribed Jieyu Anmian Formula （解郁安眠方） could be used as the basic treatment， then modified according to the performance of the patient and syndromes. For syndrome of liver depression restricting spleen， the treatment should soothe liver and invigorate spleen， resolve depression and regulate the middle； for syndrome of liver depression and phlegm coagulation， the treatment should resolve depression and phlegm， support the earth and free the wood； for syndrome of liver depression transforming into fire， the treatment should soothe liver and clear fire， resolve depression and dysphoria； for syndrome of qi stagnation and blood stasis， the treatment should activate blood and regulate the middle， resolve depression and tranquilise mind.

ObjectiveTo investigate the effect and mechanism of Dendrobium mixture （DMix）-containing serum on high glucose-induced podocyte injury in mice. MethodThe MPC5 mouse glomerular podocytes were cultured in vitro， and the optimal glucose concentration for modeling， modeling time， and concentration of DMix-containing serum for administration were determined. The cells were classified into normal （5.5 mmol·L^-1 glucose+10% blank serum）， model （30 mmol·L^-1 glucose+10% blank serum）， DMix-containing serum （30 mmol·L^-1 glucose+10% DMix-containing serum）， ferroptosis inhibitor （Fer-1， 30 mmol·L^-1 glucose+10% blank serum+1 μmol·L^-1 Fer-1） groups. The corresponding kits were used to measure the levels of Fe²⁺ and lactate dehydrogenase （LDH） in cells. Enzyme-linked immunosorbent assay was employed to determine the content of glutathione （GSH） and lipid peroxide （LPO） in cells. Fluorescence probe was used to measure the reactive oxygen species （ROS） level. Real-time fluorescence quantitative polymerase chain reaction and Western blotting were employed to determine the mRNA and protein levels， respectively， of Wilms' tumor-1 （WT-1）， desmin， long chain acyl-CoA synthase 4 （ACSL4）， and glutathione peroxidase 4 （GPX4） in podocytes. ResultCompared with the blank group， the intervention with 30 mmol·L^-1 glucose for 48 h reduced podocyte viability （P<0.01）， and the 10% DMix-containing serum showed the most significant improvement in podocyte viability （P<0.01）. Compared with the normal group， the model group presented elevated levels of Fe²⁺， LDH， LPO， and ROS， lowered GSH level， up-regulated mRNA and protein levels of desmin and ACSL4， and down-regulated mRNA and protein levels of WT-1 and GPX4 （P<0.01）. Compared with the model group， the DMix-containing serum lowered the Fe²⁺， LDH， LPO， and ROS levels， elevated the GSH level， down-regulated the mRNA and protein levels of desmin and ACSL4， and up-regulated the mRNA and protein levels of WT-1 and GPX4 in podocytes （P<0.05， P<0.01）. ConclusionDMix-containing serum exerts a protective effect on high glucose-induced podocyte injury by inhibiting ferroptosis.

Objective To investigate the causes of abnormal decrease in maximum amplitude(MA)of thromboelastog-raphy(TEG)and its effect on prognosis by monitoring the changes of coagulation-related indexes in emergency trauma pa-tients.Methods A total of 319 cases of trauma patients admitted to our hospital from September 2020 to September 2023 were retrospectively analyzed,and the coagulation-related indexes of 0 h and 24 h after admission were observed.According to the MA results,they were divided into normal MA group(>50 mm)and reduced MA group(≤50 mm)to compare the hemoglobin(Hb),platelets count(Plt),activated partial thromboplastin time(APTT),prothrombin time(PT),fibrinogen(Fib),thrombin time(TT),D-dimer(D-D),coagulation reaction time(R),clot formation kinetics(Angle),30 min clot dissolution rate(Ly30),MA,thrombine-antithrombin complex(TAT)and plasminase-α2 plasminase inhibitor complex(PIC).The correlation between MA and fibrinolysis indexes in 319 trauma patients was analyzed.According to whether tranexamic acid(TXA)was used,the reduced MA group was divided into a TXA group and a non-drug group.The differ-ences in the change of the above coagulation-related indexes,mortality rate and changes in blood product dosage were com-pared between the two groups.Results Compared with the normal MA group,Hb,Plt,Fib,diastolic blood pressure and GCS scores decreased,while heart rate,ISS score and mortality increased significantly in the reduced MA group(P<0.05).The R,PT and TT were prolonged significantly(P<0.05),and PIC and D-D increased significantly(P<0.05)in the re-duced MA group.Correlation analysis found that MA had no correlation with Ly30,TAT and APTT,but was correlated with Angle(r=0.803),Plt(r=0.544),Fib(r=0.581),PIC(r=-0.443)and D-D(r=-0.343).Compared with the non-drug group,the change of Angle,MA and FIB in the TXA group increased significantly(P<0.05),while the change of PIC de-creased(P<0.05).Cryoprecipitate and platelet transfusion in the TXA group reduced significantly(P<0.05),and red blood cell transfusion had a decreasing trend,but the difference was not significant(P>0.05).The mortality rate in the TXA group was reduced significantly(P<0.05).Conclusion Hyperfibrinolysis may be an important factor in the abnormal decrease of MA in emergency trauma patients.Treatment with TXA can improve its effect on MA,and reduce the transfusion of blood products and the patient mortality.

Purpose: Total neoadjuvant therapy (TNT) is becoming the standard of care for locally advanced rectal cancer. However, surgery is deferred for months after completion, which may lead to fibrosis and increased surgical difficulty. The aim of this study was to assess whether TNT (TNT-RAPIDO) is associated with increased difficulty of total mesorectal excision (TME) compared with long-course chemoradiotherapy (LCRT) and upfront surgery. Methods: Twelve laparoscopic videos of low anterior resection with TME for rectal cancer were prospectively collected from January 2020 to October 2021, with 4 videos in each arm. Seven colorectal surgeons assessed the videos independently, graded the difficulty of TME using a visual analog scale and attempted to identify which category the videos belonged to. Results: The median age was 67 years, and 10 patients were male. The median interval to surgery from radiotherapy was 13 weeks in the LCRT group and 24 weeks in the TNT-RAPIDO group. There was no significant difference in the visual analog scale for difficulty in TME between the 3 groups (LCRT, 3.2; TNT-RAPIDO, 4.6; upfront, 4.1; P=0.12). A subgroup analysis showed similar difficulty between groups (LCRT 3.2 vs. TNT-RAPIDO 4.6, P=0.05; TNT-RAPIDO 4.6 vs. upfront 4.1, P=0.54). During video assessments, surgeons correctly identified the prior treatment modality in 42% of the cases. TNT-RAPIDO videos had the highest recognition rate (71%), significantly outperforming both LCRT (29%) and upfront surgery (25%, P=0.01). Conclusion TNT does not appear to increase the surgical difficulty of TME.

Oolong tea is a semi-fermented tea with strong flavor, which is widely favored by consumers because of its floral and fruity aroma as well as fresh and mellow taste. During the processing of oolong tea, withering is the first indispensable process for improving flavor formation. However, the molecular mechanism that affects the flavor formation of oolong tea during withering remains unclear. Transcriptome sequencing was used to analyze the difference among the fresh leaves, indoor-withered leaves and solar-withered leaves of oolong tea. A total of 10 793 differentially expressed genes were identified from the three samples. KEGG enrichment analysis showed that the differentially expressed genes were mainly involved in flavonoid synthesis, terpenoid synthesis, plant hormone signal transduction and spliceosome pathways. Subsequently, twelve differentially expressed genes and four differential splicing genes were identified from the four enrichment pathways for fluorescence quantitative PCR analysis. The results showed that the expression patterns of the selected genes during withering were consistent with the results in the transcriptome datasets. Further analysis revealed that the transcriptional inhibition of flavonoid biosynthesis-related genes, the transcriptional enhancement of terpenoid biosynthesis-related genes, as well as the jasmonic acid signal transduction and the alternative splicing mechanism jointly contributed to the flavor formation of high floral and fruity aroma and low bitterness in solar-withered leaves. The results may facilitate better understanding the molecular mechanisms of solar-withering treatment in flavor formation of oolong tea.

Objective:Comparison of four methods in intraoperative abduction angles (AA) measurements of human cast immobilization in developmental dysplasia of the hip (DDH) by visual inspection and electronic software according to different body surface markers.Methods:Data were retrospectively collected from January 2019 to November 2021 in a total of 27 patients (54 hips) who underwent closed or simple open reduction. There were 6 males and 21 females with an average age of 13.2 months. Five doctors used visual inspection and mobile phone software to measure the AA of the hip joint immediately during the operation, and compared with the postoperative MRI measurement results (AA-MRI). The four methods of intraoperative measurement were: Junior visualization (AA-JV), the intersection angle between the line connecting the center of the popliteal fossa and the contact center of the plaster frame and the line connecting the two ischial tuberosities; the same methods as method one by Senior visualization (AA-SV); the intersection angle between the line connecting the center of the popliteal fossa and the center of the anus and the line connecting the ischial tubercle (anus-popliteal, AA-AP); the intersection of the vertical line between the center of the popliteal fossa and the groin and the horizontal line of the center of the anus and the vertical line connecting the two ischial tuberosities intersect (anus-groin crease-popliteal, AA-AGCP). The t-test, correlation coefficient, linear regression and Bland-Altman test were used to evaluate the measurements. Results:Comparing the four intraoperative and postoperative AA-MRI measurement methods, AA-JV (42.69°±4.13°) < AA-SV (44.80°±4.08°) < AA-AGCP (46.25°±5.15°) < AA-MRI (47.68°±4.21°) < AA-AP (51.77°±5.30°), and the difference between AA-JV and AA-SV, AA-AP and AA-AGCP was statistically significant ( t=2.53, P=0.013; t=5.47, P=0.001), there was no significant difference between AA-AGCP and AA-MRI ( t=1.57, P=0.118). The inter-group agreement of the five methods ICC test ranged from 0.807 to 0.892, and the intra-group average agreement of AA-MRI was 0.948. All ICC results were greater than 0.75 with good agreement. Linear regression results showed that the four intraoperative measurement methods had a good or moderate linear relationship with AA-MRI, AA-AGCP ( R 2=0.499)>AA-AP ( R 2=0.318)>AA-SV ( R 2=0.253)>AA-JV ( R 2=0.217), AA-AGCP was the best measurement method. The results of Bland-Altman scatterplot of AA-AGCP and AA-MRI were in good agreement, the mean and standard deviation of bias were -0.796±3.247, and the limit of agreement was 95% LoA (-7.16, -5.57). Conclusion:The AA method of visualization before Spica casting was smaller than truth. The method AA-AGCP objectively by landmarks was the advocated means measuring abduction angle during operation with highly consistency, agreement and easily performed.

Objective:To evaluate the effect of dexmedetomidine on the blood concentrations of ropivacaine during sciatic nerve block in rabbits.Methods:Twelve New Zealand rabbits of both sexes, weighing 2-3 kg, were randomly divided into ropivacaine group (R group) and ropivacaine mixed with dexmedetomidine group (RD group). The right femoral vein was cannulated for blood sampling in both groups, 0.375% ropivacaine 3 ml was injected around the left sciatic nerve in group R, and 0.375% ropivacaine 3 ml containing 1.5 μg/kg dexmedetomidine was injected instead in group RD.Blood samples from the right femoral vein were collected before nerve block (T 0) and at 15, 30, 45, 60, 120 and 180 min after nerve block (T 1-6) for determination of plasma concentrations of ropivacaine using high-performance liquid chromatography after centrifugation, and concentration-time curves were plotted. Results:Compared with group R, the blood concentrations of ropivacaine were significantly decreased at T 1-3 ( P<0.05), no significant change was found in the blood concentrations of ropivacaine at T 4-6 ( P>0.05), the peak blood concentration of ropivacaine was significantly decreased ( P<0.01), and no significant change was found in the time to peak blood concentrations of ropivacaine or area under the concentration-time curves in group RD ( P>0.05). Conclusions:Dexmedetomidine can decrease the blood concentrations of ropivacaine during sciatic nerve block in rabbits.

Objective:To explore the effect of core muscle group training combined with balance cup therapy in patients with chronic nonspecific low back pain.Methods:From January 2017 to December 2019, convenience sampling method was used to select 130 patients with chronic nonspecific low back pain in Guangdong Province Foshan Hospital of Traditional Chinese Medicine. According to the random number table, patients were divided into core muscle group and combined treatment group, with 65 cases in each group. The core muscle group was given the Swiss ball to perform core muscle training in the order of sitting, double bridge, knee flexion double bridge, reverse bridge and push-ups. The combined treatment group was given a balance tank based on core muscle training, followed by flash tank, walking tank, and sitting tank treatment. After 4 weeks of intervention, we compared the scores of the Visual Analogue Scale (VAS) , Roland-Morris Disability Questionnaire (RMDQ) , Finger-Floor Distance (FFD) , and static and dynamic muscle endurance time, and the total effective rate of treatment between the two groups of patients.Results:After intervention, the scores of VAS, RMDQ and FFD of combined treatment group were lower than those of core muscle group, and the differences were statistically significant ( P<0.01) . The static and dynamic muscle endurance time of combined treatment group were higher than those of core muscle group, and the differences were statistically significant ( P<0.01) . The total effective rate of combined treatment group was 90.77% (59/65) , which was higher than 76.92% (50/65) of core muscle group, and the difference was also statistically significant ( P<0.05) . Conclusions:Core muscle training combined with balance cup therapy can reduce the degree of pain in patients with chronic nonspecific low back pain, improve waist dysfunction, waist flexibility and muscle endurance, and have good clinical effects.
