It is believed that Shengyang Yiwei Decoction （升阳益胃汤， SYD） is effective in regulating the flow of Qi （气）， and can treat various diseases caused by the disorder of the spleen and stomach Qi. In clinical practice， based on the pathological characteristics of children often having insufficient spleen， and adhering to the principle of treating different diseases with the same method， the focus is placed on the core pathogenesis of spleen and stomach Qi disharmony. We use SYD in various pediatric conditions such as allergic rhinitis， post COVID-19 condition， urethral syndrome， and dysfunctional uterine bleeding in adolescence， and emphasize the treatment is flexibly tailored to the symptoms.

Metachromatic leukodystrophy (MLD) is an inherited disease caused by a deficiency of the enzyme arylsulfatase A (ARSA). Lentivirus-modified autologous hematopoietic stem cell gene therapy (HSCGT) has recently been approved for clinical use in pre and early symptomatic children with MLD to increase ARSA activity. Unfortunately, this advanced therapy is not available for most patients with MLD who have progressed to more advanced symptomatic stages at diagnosis. Patients with late-onset juvenile MLD typically present with a slower neurological progression of symptoms and represent a significant burden to the economy and healthcare system, whereas those with early onset infantile MLD die within a few years of symptom onset. We conducted a pilot study to determine the safety and benefit of HSCGT in patients with postsymptomatic juvenile MLD and report preliminary results. The safety profile of HSCGT was favorable in this long-term follow-up over 9 years. The most common adverse events (AEs) within 2 months of HSCGT were related to busulfan conditioning, and all AEs resolved. No HSCGT-related AEs and no evidence of distorted hematopoietic differentiation during long-term follow-up for up to 9.6 years. Importantly, to date, patients have maintained remarkably improved ARSA activity with a stable disease state, including increased Functional Independence Measure (FIM) score and decreased magnetic resonance imaging (MRI) lesion score. This long-term follow-up pilot study suggests that HSCGT is safe and provides clinical benefit to patients with postsymptomatic juvenile MLD.

Objective To evaluate the effect of pneumatic logistics transport system(PTS)on the trans-portation efficiency of the transferred samples and the accuracy of the results.Methods The transportation speed,temperature and humidity change of PTS were analyzed by temperature and humidity transmitter.Anti-coagulant samples containing disodium ethylenediaminetetraacetate(EDTA-K2),sodium citrate,lithium hepa-rin and samples containing inert separation gel coagulant were selected.and used respectively for complete blood cell analysis,prothrombin time(PT),activated partial prothrombin time(APTT),troponin T(TnT)and other myocardial markers,as well as the detection of items such as glucose(Glu)and lactate dehydrogen-ase(LDH).According to the transfer mode,they were divided into the manual transfer group and the PTS transfer group,and according to the number of PTS transfers,they were divided into the one-time transfer group,the three-time transfer group and before transfer(control).The differences among each group were statistically analyzed,and 1/3 allowable total error(1/3TEa)was adopted as the criterion for determining the clinical application value.Results There was no statistically significant difference in the changes of tempera-ture and humidity during the transportation process of PTS compared with manual transportation(P＞0.05),but it was significantly faster than manual transportation in terms of transportation time(P＜0.05).Com-pared with before transfer,the differences between the PT,APTT,Glu and LDH items in the one-time trans-fer group and the three-time transfer group were statistically significant(P＜0.01),and their deviations were all much greater than 1/3TEa.However,in the plasma samples,compared with before transport,there were statistically significant differences in Glu and LDH between the one-time transfer group and the three-time transfer group(P＜0.05),but the deviations were all less than 1/3TEa.For the items of TnT,red blood cell count and hematocrit,compared with before transfer,there were statistically significant differences between some groups of the one-time transfer group and the three-time transfer group(P＜0.05),but the deviations were all less than 1/3TEa.Conclusion PTS can significantly improve the transportation efficiency of sam-ples,but it significantly affects the detection of Glu and LDH in plasma samples,which can be improved by u-sing serum sample transportation instead.In addition,PTS also affects the detection of PT and APTT,and it is not recommended to use PTS to transport coagulation specimen.

OBJECTIVE To evaluate the cost-effectiveness of apatinib combined with adriamycin in the second-line chemotherapy of platinum-resistant recurrent ovarian cancer （OC） from the perspective of the health system in China. METHODS A three-state partitioned survival model was constructed based on the APPROVE clinical trial and related literature data， with a model simulation time frame of 10 years and a 4-week cycle， and both cost and utility values were discounted using a 5% discount rate. Cost and quality-adjusted life years （QALYs） were used as a model output indicator and the incremental cost-effectiveness ratio （ICER） was calculated to evaluate the cost-effectiveness of apatinib combined with adriamycin versus adriamycin chemotherapy in the second-line treatment of platinum-resistant recurrent OC. One-way sensitivity analysis， probability sensitivity analysis and scenario analysis were used to verify the robustness of the base-case analysis results. RESULTS The results of base-case analysis indicated that compared with chemotherapy alone， ICER of patients receiving apatinib combined with adriamycin was 124 678.25 yuan/QALY， which was less than willingness-to-pay （WTP） threshold set in this study [3 times per capita gross domestic product （GDP） of China in 2022 （257 094 yuan）]. The results of scenario analysis showed that， with the extension of the simulation time limit， the ICER of apatinib combined with adriamycin was gradually reduced， and the decline was gradually reduced， but both were less than WTP threshold. The results of single factor sensitivity analysis showed that the factors that had the greatest impact on ICER were the utility value of progression， body surface area， discount rate，and the cost of best supportive treatment， etc. The results of probability sensitivity analysis showed that under WTP threshold set in this study， the economic probability of apatinib combined with adriamycin was about 99%. CONCLUSIONS From the perspective of China’s health system， using three times the per capita GDP in 2022 as the WTP threshold， the combination of apatinib and adriamycin is more cost-effective than adriamycin alone in second-line chemotherapy for platinum-resistant recurrent OC.

ObjectiveTo explore the effect of precocious puberty on glucose metabolism and lipid metabolism in female rats. MethodsSixty two-day-old female rats were randomly divided into 2 groups. When aged 5 days， the precocious puberty group and normal group were given a single subcutaneous injection of danazol and solvent soybean oil respectively. The vaginal opening of rats was monitored from their 21 days of age. After 12 hours of fasting， all successful modeling rats were randomly executed within 3 days after vaginal opening， when aged 7 and 12 weeks. Then we measured the rats’ body weight and length， determined the concentrations of glucose， insulin， blood lipids， estradiol， leptin and adiponectin with enzyme-linked immunosorbent assay and observed the pathological changes of perirenal fat， uterus and ovary. ResultsFor body weight and length， rats in the precocious puberty group were smaller than those in the normal group within 3 days after vaginal opening， but which did not affect their subsequent growth and development， and there was no significant difference between the two groups at 7 and 12 weeks of age. Within 3 days after vaginal opening， insulin levels had significant difference between the two groups （P = 0.001）， the precocious group showed hyperinsulinemia and increased number of perirenal adipocytes. At three execution times， no significant difference was noted in estradiol， leptin and adiponectin levels between the two groups. The same was true in the ratios of ovary or uterus to body weight between the two groups. ConclusionsPrecocious puberty makes earlier onset of pubertal development and allows body maladaptation to the sudden changes of the internal environment. However， the changes due to precocious puberty are temporary and reversible， and they may become normal in adulthood.

Refractory angina is characterized by recurrent and persistent angina with a duration of not less than three months， which is related to reversible ischemia and hypoxia caused by coronary stenosis and obstruction. It mainly involves obstructive coronary artery disease and non-obstructive coronary artery disease with coronary artery spasm and coronary microvascular dysfunction. “Stasis and toxin” play an important role in the pathogenesis of cardiovascular diseases. The pathogenesis of stasis and toxin is stubborn filthy turbidity featured by slow accumulation and sudden onset，and rapid changes，which coincides with the characteristics of refractory angina which is complex and changeable，prolonged and difficult to cure. The pathogenesis of refractory angina involves a combination of underlying deficiency and excessive manifestation， with "stasis and toxin" playing a crucial role as an important pathological factor in the whole process of refractory angina. Traditional Chinese medicine （TCM） employs a holistic approach known as "activating blood circulation and removing toxins"， which is supplemented by various methods to tonify Qi and warm Yang， nourish the kidneys and invigorate the spleen， clear heat and transform phlegm. This approach applies anti-inflammatory measures， regulates lipid metabolism， inhibits oxidative stress and thrombus formation， protects endothelial function in blood vessels， as well as establishes collateral circulation for the prevention and treatment of refractory angina. Therefore，based on the theory of "stasis and toxin"，combined with TCM theory and modern medical research，this paper discusses the pathogenesis of refractory angina and the prevention and treatment strategy of TCM，and elucidates the reasons for the difficulty in curing refractory angina and the relationship between refractory angina and common angina pectoris，coronary microvascular dysfunction，coronary artery spasm and obstructive coronary artery disease，hoping to provide certain theoretical basis and clinical ideas for the prevention and treatment of refractory angina with TCM.

BackgroundChronic insomnia is characterized by a prolonged and recurrent course. The efficacy of repeated transcranial magnetic stimulation （rTMS） as a physical therapy method to improve sleep quality remains inadequately supported by evidence， particularly regarding its relationship with personality traits. ObjectiveTo explore the efficacy and influencing factors of rTMS in the treatment of chronic insomnia， and to provide insights into its therapeutic potential. MethodA total of 46 patients who met the diagnostic criteria for chronic insomnia according to the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5）， and were treated at the Third Hospital of Mianyang from September 2022 to September 2023 were selected. Prior to treatment， participants underwent assessments using the Eysenck Personality Questionnaire （EPQ）， Hamilton Depression Scale-17 item （HAMD-17） and Hamilton Anxiety Scale （HAMA）. The Pittsburgh Sleep Quality Index （PSQI） was used to assess sleep quality before treatment， at the end of the second week of treatment and one week post-treatment. ResultsAt the end of the second week of treatment， patients exhibited significantly improved total PSQI score and subscale scores related to subjective sleep quality， sleep latency， sleep duration， sleep efficiency， sleep disturbance and daytime dysfunction （t=4.755~13.361， P<0.01）， with 24 cases （54.35%） showing effective treatment outcomes. Multiple linear regression analysis showed that introverted and extroverted personality traits contributed significantly to the regression equation （B=0.317， P<0.01）， explaining 29.90% of the total variation （R²=0.299）. ConclusionrTMS treatment may effectively improve the sleep quality of patients with chronic insomnia， with its therapeutic effect appearing to associated with introverted and extroverted personality traits. ［Funded by National Natural Science Project of China （number， 82372080）］

Objective:To observe the effects of proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor combined with rosuvastatin on lipid levels and short-term prognosis in patients with acute ischemic stroke, and to explore the optimal therapeutic regimen in terms of efficacy and safety, so as to provide a basis for clinical practice.Methods:Consecutive patients with acute cerebral infarction within 72 hours of onset and lipids≥2.6 mmol/L admitted to Xuzhou Central Hospital from April 2022 to March 2023 were included in the study, and the randomized numeric table method was used to divide them into 3 groups of different treatment regimens, group A (rosuvastatin 20 mg, once a day), group B (rosuvastatin 10 mg, once a day+alirocumab 75 mg, once 2 weeks) and group C (rosuvastatin 20 mg, once a day+alirocumab 75 mg, once 2 weeks). General baseline data, National Institutes of Health Stroke Scale score, modified Rankin Scale score on day 90 and the occurrence of adverse events and serious adverse events were collected from the 3 groups. The primary efficacy outcome was the degree of reduction in low density lipoprotein-cholesterol (LDL-C) from baseline on day 90. The secondary efficacy outcomes were recurrence rate and time to recurrence in stroke patients within 90 days,etc. The primary safety outcome was hepatic insufficiency (transaminase elevation≥3 times normal) within 90 days. The secondary safety outcomes were death due to stroke within 90 days and fatal and nonfatal myocardial infarction.Results:A total of 501 patients were included, 166 patients in group A, 167 patients in group B, and 168 patients in group C. The differences in the baseline data of the 3 groups were not statistically significant (all P>0.05). LDL-C was reduced from baseline on day 90 in groups A, B, and C, with the differences of -1.5 (-1.7, -1.4) mmol/L, -2.2 (-2.5, -2.1) mmol/L and -2.2 (-2.6, -2.1) mmol/L, respectively, with statistically significant differences among the 3 groups ( H=1.497, P<0.001); the differences between the group A and group B, and between the group A and group C, were statistically significant ( Z=-11.125, P=0.006; Z=-9.475, P=0.012), while the difference between the group B and group C was not statistically significant ( Z=1.650, P=0.946). The numbers of 90-day stroke recurrence cases (recurrence rate) in patients in the groups A, B, and C were 12 (7.2%), 4 (2.4%), and 5 (3.0%), respectively, without statistically significant difference among the 3 groups ( χ 2=5.773, P>0.05); the recurrence time of patients in the groups A, B and C was (43.0±7.4) d, (66.0±8.3) d and (62.2±5.6) d, respectively, and the differences among the 3 groups were statistically significant ( F=14.096, P=0.001). Compared with the group A, patients in the groups B and C had a prolonged time to stroke recurrence within 90 days ( Z=-3.108, P=0.002; Z=-2.871, P=0.004), whereas the difference in the time to stroke recurrence within 90 days between patients in the groups B and C was not statistically significant ( Z=0.397, P=0.692). The time to stroke recurrence within 90 days was positively correlated with the level of LDL-C on day 90 ( β=0.850, P=0.031). Ten patients (6.0%) in the group A developed hepatic insufficiency, 1 patient (0.6%) in the group B, and 9 patients (5.4%) in the group C. The differences among the 3 groups were statistically significant (χ 2=7.622, P=0.022); and the difference between the group B and group C was statistically significant ( P=0.011). The differences of secondary safety endpoints, death due to stroke within 90 days [1 case (0.6%) in the group A, 0 case (0) in the group B, and 1 case (0.6%) in the group C], fatal and nonfatal myocardial infarction within 90 days [3 cases (1.8%) in the group A, 1 case (0.6%) in the group B, and 1 case (0.6%) in the group C], were not statistically significant among the 3 groups (all P>0.05). Conclusions:In patients with acute ischemic stroke, PCSK9 inhibitor combined with rosuvastatin (both medium and high doses) significantly reduced LDL-C levels compared with baseline, and at the same time prolonged the time to stroke recurrence, reduced adverse effects such as hepatic insufficiency, and had a high degree of safety. PCSK9 inhibitor combined with medium-dose rosuvastatin had a better effect.

Objective:To observe the change of retinal artery angle in eyes with idiopathic epiretinal membrane (ERM) and to analyze the relationship between retinal artery angle, ERM classification based on optical coherence tomography (OCT), and visual acuity.Methods:A retrospective cross-sectional clinical study. A total of 187 eyes in 187 patients diagnosed with monocular idiopathic ERM (IERM group) in Department of Ophthalmology of Zhejiang Provincial People's Hospital and the Affiliated Eye Hospital of Wenzhou Medical University at Hangzhou from November 2018 to January 2023 were included in the study. The contralateral healthy eyes were included as the control group. All patients underwent best corrected visual acuity (BCVA), fundus photography, spectral-domain OCT, OCT angiography (OCTA) and axial length (AL) measurement. BCVA examination was performed using the standard logarithmic visual acuity chart, which was converted to the logarithm of the minimum angle of resolution (logMAR) visual acuity. The foveal avascular zone (FAZ) area was measured by OCTA. The central macular thickness (CMT) was measured by spectral domain OCTaccording to the grading criteria of ectopic inner foveal layer (EIFL) was divided into stages 1 to 4 with 42, 45, 62, and 38 eyes, and the IERM group was subdivided into stage 1, stage 2, stage 3, and stage 4 groups accordingly. Image J was used to measure the retinal artery angle and the 1/2 retinal artery angle on fundus images. Multiple linear regression analysis was used to analyze the correlation between BCVA and artery angle, 1/2 artery Angle, CMT, FAZ area and AL.Results:Compared with the control group, eyes in IERM group had worse BCVA ( t=9.727), thicker CMT ( t=12.452), smaller FAZ area ( t=-14.329), smaller artery angle ( t=-9.165) and smaller 1/2 artery angle ( t=-9.549). The differences were statistically significant ( P<0.001). With the increase of IERM stage, the artery angle and 1/2 artery angle decreased significantly ( F=21.763, 12.515; P<0.001). There was no significant difference in artery angle and 1/2 artery angle between stage 1 group and stage 2 group, and 1/2 arterial angle between stage 2 group and stage 3 group ( P>0.05). There were significant differences in artery angle and 1/2 artery angle between the other groups ( P<0.05). There were significant differences in CMT and logMAR BCVA among different classification subgroups in IERM groups ( P<0.05). There was no significant difference in FAZ area between grade 3 group and grade 4 group ( P>0.05). There were significant differences in FAZ area between the other groups ( P<0.05). Correlation analysis showed that decreased artery angle ( P=0.013) and increased CMT ( P<0.001) were associated with decreased BCVA. Conclusions:Compared with healthy eyes, the artery angle decreases significantly with the increase of ERM stage. Decreased retinal artery angle is associated with decreased visual acuity in IERM eyes.
