OBJECTIVE To evaluate the effectiveness and safety of Panlongqi tablets in the treatment of fractures based on real-world research. METHODS From September 2021 to September 2023， fracture patients admitted to 33 medical institutions were collected retrospectively. Patients who received conventional treatment were divided into control group （n＝3 750）， and patients who received combination of Panlongqi tablets on the basis of conventional treatment were divided into observation group （n＝ 3 706）. Self-reported indicators of patients were collected through telephone follow-up at 0， 4， 7 and 14 days after treatment. The improvement values of pain score， swelling score and health utility value， as well as effective rate and adverse drug reactions were compared between 2 groups. The propensity matching score （PSM） method was adopted to perform baseline matching on patient’s age， gender， fracture site， fracture severity， surgical type， type of hospital， and other indicators. Statistical analysis was performed on each therapeutic effect indicator. RESULTS After PSM， a total of 6 425 patients were included， of which 3 055 were in the observation group and 3 370 were in the control group. After 14 days of treatment， the observation group showed significant improvement in pain score （4.768 vs. 4.353）， swelling fangshiyuan2008@126.com grading score （2.979 vs. 2.391）， and life quality utility value （0.430 vs. 0.363）， as well as effective rate （87.20% vs.75.99%） compared to the control group （P＜0.05）. The results of subgroup analyses conducted by gender， age， hospital type， and fracture site were consistent with the aforementioned results. In terms of safety， the observation group had no serious adverse reactions， with a total of 29 cases of mild adverse reactions such as dizziness， stomach pain， and allergies， with an incidence rate of 0.78%. CONCLUSIONS Panlongqi tablets combined with conventional treatment are significantly better than conventional treatment in improving pain， swelling， quality of life， and effective rate in patients with fractures， and have good safety.

Objective To screen the pharmacodynamic material basic components of Artemisiae Annuae Herba and study its antioxidant activity in vitro by investigating the spectrum-effect relationship between the HPLC fingerprints of 11 batches of Artemisiae Annuae Herba(dried aerial part of Artemisia annua L.).Methods The determination was performed on Aglient C18 column(250 mm×4.6 mm,5 μm)with mobile phase consisted of 0.2%phosphoric acid solution-Methanol(gradient elution)at the flow rate of 1.0 ml/min.The column temperature was indoor temperature,and detection wavelength was 220 nm,with sample size of 10 μl.Using isochlorogenic acid A as reference,HPLC fingerprints of 11 batches of samples were determined.The common peaks of 11 batches of samples were identified and recorded through TCM chromatographic fingerprint similarity evaluation system(2012 edition).Using scavenging rate of DPPH and ABTS free radical as pharmacodynamic indicators of antioxidant effects,SIMCA 14.1 analysis software was used for PLSR to establish the spectra-effect relationship.Results There were 48 common peaks on 11 batches of sample,11 components were identified as scopoletin,scoparone,isochlorogenic acid B,A,C,luteolin,apigenin,chrysosplenetin,artemisinin,artemisetin and artemisinic acid.The scavenging activity of 11 batches of samples to DPPH and ABTS free radicals was detected.The spectrum-effect relationship showed that isochlorogenic acid A,B,C and scoparone were positively associated with its antioxidant capacity,and variable projection value was greater than 1.It was suggested that these components were the material basis of antioxidant effect in Artemisiae Annuae Herba.Conclusion This study investigates the antioxidant capacity of different substances in Artemisiae Annuae Herba in vitro,and proves that isochlorogenic acid A,B,C and scoparone play a major role for the antioxidant capacity.

Objective To analyze the risk factors for extrauterine growth retardation(EUGR)in late preterm infants appropriate for gestational age.Methods The clinical data in 1 402 preterm infants appropri-ate for gestational age delivered and hospitalized in this hospital from January 2016 to June 2022 were analyzed retrospectively.They were divided into the EUGR group(n=244)and the non-EUGR group(n=1 158)ac-cording to whether or not the body weight at discharge was below the 10th percentile of the growth curve for the same gestational age at the same period based on the Fenton's preterm growth curve.The clinical data of preterm infants and mothers of the two groups were collected.The risk factors for EUGR occurrence in pre-mature infants were analyzed.Results Among 1 402 preterm infants appropriate for gestational age,EUGR occurred in 244 cases with the EUGR incidence rate of 17.4％.The EUGR incidence rate had no statistical difference among the different fetal ages of premature infants(P＞0.05).The EUGR incidence rate had sta-tistical difference among different birth weights of premature infants(P＜0.05).The logistic regression anal-ysis showed that male(OR=1.694,95％CI:1.144-2.507),low birth weight(OR=0.989,95％CI:0.988-0.991),feeding intolerance(OR=2.719,95％CI:1.234-5.990),short gestational weeks(OR=0.146,95％CI:0.103-0.207)and hospitalization duration extension(OR=1.073,95％CI:1.031-1.117)were the risk factors for EUGR occurrence in late premature infants appropriate for gestational age in discharge.The sub-group analysis showed that male,low birth weight,feeding intolerance and hospitalization duration extension were the risk factors for EUGR occurrence in the preterm infants with gestational ages of 34-＜36 weeks(P＜0.05).Low birth weight and feeding intolerance only affected the preterm infants≥36 weeks of gesta-tional age(P＜0.05).Conclusion Strengthening the pregnant duration health care and active nutritional sup-port after birth may reduce the risk of EUGR occurrence in late premature infants.

The recurrent neural network architecture improves the processing ability of time-series data. However, issues such as exploding gradients and poor feature extraction limit its application in the automatic diagnosis of mild cognitive impairment (MCI). This paper proposed a research approach for building an MCI diagnostic model using a Bayesian-optimized bidirectional long short-term memory network (BO-BiLSTM) to address this problem. The diagnostic model was based on a Bayesian algorithm and combined prior distribution and posterior probability results to optimize the BO-BiLSTM network hyperparameters. It also used multiple feature quantities that fully reflected the cognitive state of the MCI brain, such as power spectral density, fuzzy entropy, and multifractal spectrum, as the input of the diagnostic model to achieve automatic MCI diagnosis. The results showed that the feature-fused Bayesian-optimized BiLSTM network model achieved an MCI diagnostic accuracy of 98.64% and effectively completed the diagnostic assessment of MCI. In conclusion, based on this optimization, the long short-term neural network model has achieved automatic diagnostic assessment of MCI, providing a new diagnostic model for intelligent diagnosis of MCI.

Objective:To explore the clinical characteristics of patients with pituitary thyrotropin-secreting adenoma and evaluate the effect of preoperative short-acting octreotide treatment on hyperthyroidism.Methods:A retrospective analysis was performed in 40 patients with pituitary thyrotropin adenoma diagnosed in Beijing Tiantan Hospital from January 2008 to January 2018. The general data, laboratory examinations and imaging findings were reviewed and analyzed. The clinical effect of preoperative octreotide on hyperthyroidism was evaluated.Results:The age of onset year of the 40 patients (male: female = 24∶16) was (30.5±5.1) years. Among them, 35 patients (87.5%) were with macroadenoma. The most common symptoms were thyroid hypermetabolism syndrome, followed by headache, dizziness, visual field damage and hypogonadism. The thyroid function of 30 patients (75%) recovered to normal within 3-5 days after the octreotide treatment. The total effective rate of the octreotide was 90.0%. The level of free thyroxine (FT 4) before treatment in patients with more than 10 times of effective cumulative dose was significantly higher than that in patients with less than 10 doses. Conclusions:Thyroid hypermetabolism syndrome and pituitary occupying effect are the most common clinical manifestations of thyrotropin-secreting adenoma. Preoperative octreotide treatment can effectively control hyperthyroidism. The level of FT 4 is a crucial factor affecting the efficacy of octreotide.

Objective:To analyze the effect of long-acting somatostatin treatment on blood glucose, blood lipid, insulin resistance and islet function in patients with acromegaly after surgical treatment.Methods:Self-control study before and after treatment was used. A total of 30 subjects who were diagnosed as acromegalyand received surgical treatment in Beijing Tiantan Hospital from January 2016 to January 2018 were enrolled in this study. Because patients′ growth hormone (GH) level was notc ompletely controlled after surgery, all the patients were treated with long-acting octreotide for more than 1 year. Before and 1 year after treatment, oral glucose tolerance testing (OGTT) was performed at pretreatment and 1 year after initiation of treatment with long-acting octreotide. Homeostatic model assessment (HOMA) was used to estimate insulin resistance (HOMA-IR) and β-cell function (HOMA-β). The HOMA-IR and HOMA-β were detected by 75 g glucose, insulin, C peptide release test and growth hormone suppression test to evaluate the therapy effects on insulin resistance and islet function.Results:The levels of GH, insulin-like growth factor 1(IGF-1), HOMA-IR, HOMA-β, and triacylglycerol(TG) were all decreased after 1 year of octreotide treatment compared with that before treatment: (2.8 ± 2.5) μg/L vs. (12.1 ± 10.5) μg/L, (356.8 ± 209.2) μg/L vs. (698.1 ± 207.3) μg/L, 1.56 ± 1.08 vs. 2.71 ± 1.52, 1.01 ± 0.97 vs. 4.87 ± 3.57, (1.12 ± 0.49) mmol/L vs. (1.76 ± 0.92) mmol/L, and the differences were statistically significant ( P<0.05). After treatment, the level of fasting blood glucose was increased compared with that before treatment: (5.83 ± 1.19) mmol/L vs.(5.11 ± 1.73) mmol/L, and the difference was statistically significant ( P<0.05). While there were no significant changes in postprandial 2 h blood glucose and glycosylated hemoglobin (GHb), total cholesterol (TC), low-density lipoprotein cholesterol(LDL-C) and high-density lipoprotein cholesterol (HDL-C) levels before and after treatment ( P>0.05). Conclusions:Long-acting somatostatin therapy can effectively improve the insulin sensitivity of acromegaly patients, reduce β cell function, and slightly increase fasting blood glucose. It has no adverse effect on GHb, and can reduce the level of TG of the patients.

Objective:To summarize and analyze the clinical data of Chinese patients with colony-stimulating factor 1 receptor (CSF1R)-related leukoencephalopathy, and clarify the phenotypic and genetic characteristics of Chinese patients.Methods:Medical history of patients with CSF1R-related leukoencephalopathy diagnosed from April 1, 2018 to January 31, 2021 in the department of neurology of 22 hospitals in China was collected, and scores of Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment Scale (MoCA), magnetic resonance severity scale were evaluated. Group comparison was performed between male and female patients.Results:A total of 62 patients were included, and the male-female ratio was 1∶1.95. The age of onset was (40.35±8.42) years. Cognitive impairment (82.3%, 51/62) and motor symptoms (77.4%,48/62) were the most common symptoms. The MMSE and MoCA scores were 18.79±7.16 and 13.96±7.23, respectively, and the scores of two scales in male patients (22.06±5.31 and 18.08±5.60) were significantly higher than those in females (15.53±7.41 , t=2.954, P=0.006; 10.15±6.26, t=3.328 , P=0.003). The most common radiographic feature was bilateral asymmetric white matter changes (100.0%), and the magnetic resonance imaging severity scale score was 27.42±11.40, while the white matter lesion score of females (22.94±8.39) was significantly higher than that of males (17.62±8.74 , t=-2.221, P<0.05). A total of 36 CSF1R gene mutations were found in this study, among which c.2381T>C/p.I794T was the hotspot mutation that carried by 17.9% (10/56) of the probands. Conclusions:The core phenotypic characteristics of CSF1R-related leukoencephalopathy in China are progressive motor and cognitive impairment, with bilateral asymmetrical white matter changes. In addition, there exist gender differences clinically, with severer cognitive impairment and imaging changes in female patients. Thirty-six CSF1R gene mutations were found in this study, and c.2381T>C/p. I794T was the hotspot mutation.

Objective:To summarize the clinical characteristics and treatment of pituitary thyrotropin mixed secreting adenoma.Methods:The clinical data of 9 patients with pituitary thyrotropin mixed secreting adenoma from January 2008 to December 2019 in Beijing Tiantan Hospital, Capital Medical University, were retrospectively analyzed.Results:Among 9 patients, male was in 7 cases, and female in 2 cases; age was (35.7 ± 13.5) years; course of disease was (3.8 ± 3.1) years; mixed thyrotropin and growth hormone secreting adenoma was in 6 cases; most of them were accompanied with different degrees of thyrotoxicosis, 6 with acromegaly and 2 with amenorrhea and lactation. All the tumors were pituitary macroadenoma, with aggressive growth. Only 1 patient was completely relieved after operation, and most patients needed combined treatment to control the disease.Conclusions:Mixed thyrotropin and growth hormone secreting adenoma is the most common type of the disease, the clinical manifestations are complex, and the tumor is aggressive growth, surgical treatment can not be completely relieved and radiotherapy and/or combination of medicine treatment can help to improve the condition.
