OBJECTIVE To sort out the evaluation mechanism and methodology of published cases of comprehensive clinical evaluation of drugs in China， and provide a reference for promoting standardized comprehensive clinical evaluation of drugs and strengthening policy transformation in China. METHODS Clinical comprehensive evaluation cases of drugs published in China from CNKI， Wanfang Data， PubMed and Web of Science were systematically searched， and the retrieval time was from the inception to December 31st， 2023. The summary and analysis were performed from the aspects of theme selection， indicator system construction， evaluation methods， comprehensive decision-making， quality control， etc. RESULTS A total of 143 pieces of literature were ultimately included from 2014 to 2023. The number of publications has shown a rapid upward trend since 2019. The subjects of the evaluation cases were mainly pediatric drugs， Chinese patent medicines， cardiovascular drugs and anti-tumor drugs. The evaluation dimensions were between 3-8， all involving safety and effectiveness dimensions. Most cases adopted rapid evaluation methods based on literature review and expert interviews/questionnaire surveys with less emphasis on real-world research. Most cases did not involve comprehensive decision-making， quality control， or policy transformation. CONCLUSIONS The clinical comprehensive evaluation of drugs in China has made rapid progress under the guidance of national policies. However， there are still issues and challenges such as incomplete evaluation methods and standards， few cases of evaluation results being converted into decision-making， and a lack of quality control mechanisms. It is suggested that standardized evaluation paths and quality control mechanisms should be explored； when the evidence-based basis is insufficient， real-world research should be conducted as much as possible， so as to accelerate the policy transformation of evaluation results.

INTRODUCTION: Lecanemab has shown promise in treating early Alzheimer's disease (AD), but its safety and efficacy in Chinese populations remain unexplored. This study aimed to evaluate the safety and 6-month clinical outcomes of lecanemab in Chinese patients with mild cognitive impairment (MCI) or mild AD. METHODS: In this single-arm, real-world study, participants with MCI due to AD or mild AD received biweekly intravenous lecanemab (10 mg/kg). The study was conducted at Hainan Branch, Ruijin Hospital Shanghai Jiao Tong University School of Medicine. Patient enrollment and baseline assessments commenced in November 2023. Safety assessments included monitoring for amyloid-related imaging abnormalities (ARIA) and other adverse events. Clinical and biomarker changes from baseline to 6 months were evaluated using cognitive scales (mini-mental state examination [MMSE], montreal cognitive assessment [MoCA], clinical dementia rating-sum of boxes [CDR-SB]), plasma biomarker analysis, and advanced neuroimaging. RESULTS: A total of 64 patients were enrolled in this ongoing real-world study. Safety analysis revealed predominantly mild adverse events, with infusion-related reactions (20.3%, 13/64) being the most common. Of these, 69.2% (9/13) occurred during the initial infusion and 84.6% (11/13) did not recur. ARIA-H (microhemorrhages/superficial siderosis) and ARIA-E (edema/effusion) were observed in 9.4% (6/64) and 3.1% (2/64) of participants, respectively, with only two symptomatic cases (one ARIA-E presenting with headache and one ARIA-H with visual disturbances). After 6 months of treatment, cognitive scores remained stable compared to baseline (MMSE: 22.33 ± 5.58 vs . 21.27 ± 4.30, P = 0.733; MoCA: 16.38 ± 6.67 vs . 15.90 ± 4.78, P = 0.785; CDR-SB: 2.30 ± 1.65 vs . 3.16 ± 1.72, P = 0.357), while significantly increasing plasma amyloid-β 42 (Aβ42) (+21.42%) and Aβ40 (+23.53%) levels compared to baseline. CONCLUSIONS: Lecanemab demonstrated a favorable safety profile in Chinese patients with early AD. Cognitive stability and biomarker changes over 6 months suggest potential efficacy, though high dropout rates and absence of a control group warrant cautious interpretation. These findings provide preliminary real-world evidence for lecanemab's use in China, supporting further investigation in larger controlled studies. REGISTRATION ClinicalTrials.gov , NCT07034222.

OBJECTIVE: To investigate the clinical characteristics and prognosis of patients with IgD multiple myeloma (MM). METHODS: The clinical data of 8 patients with IgD MM admitted to Gansu Provincial Hospital from September 2013 to February 2023 were collected, and their clinical characteristics and prognosis were retrospectively analyzed and summarized. RESULTS: Among the 8 enrolled patients, there were 4 males and 4 females, with a median age of 60 (44-74) years. All patients had symptoms of renal insufficiency and anemia. There were 3 cases of bone invasion, 3 cases of splenomegaly, 7 cases of IgD-λ type, and 1 case of IgD-κ type. FISH examination was performed in 7 cases, and 6 of them were positive for 1q21 . There were 6 cases in DS stage III and 2 cases in DS stage II; According to ISS staging, there were 6 cases in stage III, 1 case in stage II, and 1 case in stage I; According to R-ISS staging, there were 5 cases in stage III and 3 cases in stage II. All patients received bortezomib-based combination chemotherapy, with 1 case undergoing autologous stem cell transplantation (ASCT) and 2 cases receiving daratumumab in combination. The median treatment period was 6 (1-15) cycles. The short-term efficacy was evaluated after 4-6 courses of treatment. Among the 6 patients with assessable efficacy, 1 case experienced disease progression (PD), and 5 cases achieved complete remission (CR). The median follow-up time was 26 (11-33) months, and the median progression-free survival (PFS) and median overall survival (OS) of the patients were 11.25 (3-26) months and 18.5 (4-33) months, respectively. Among the 8 patients, 4 cases died. Among the deceased patients, 3 cases were in R-ISS stage III and 3 cases were 1q21 positive. 2 of the 5 patients with early CR died due to disease progression. CONCLUSION The incidence of IgD MM is low, the symptoms of early renal damage, blood system damage and bone erosion in IgD MM patients are obvious, and the median survival time is short. ASCT and / or daratumumab may bring lasting relief for IgD MM patients, but large-scale clinical studies are still needed.

OBJECTIVE: To explore the significance of the plasma cell percentage and immature plasma cells in the prognosis of patients with multiple myeloma (MM). METHODS: The clinical data of 126 newly diagnosed MM patients in Gansu Provincial Hospital from June 2017 to November 2022 were retrospectively analyzed. The enrolled patients were divided into a higher plasma cell percentage group (group A) and a lower plasma cell percentage group (group B) according to the median plasma cell percentage (33.5%). The clinicopathological data of the two groups were compared, and the effect of plasma cell percentage on the prognosis of MM patients was analyzed using survival curves. On this basis, group A and group B were divided into subgroups with immature plasma cells (A1 group, B1 group) and subgroups without immature plasma cells (A2 group, B2 group), respectively, then the survival curves were used to analyze the effect of immature plasma cells on the prognosis of MM patients. RESULTS: Among the 126 patients with MM, the proportions of patients with ISS stage III, elevated β₂-microglobulin(β₂-MG) level, and immature plasma cells in Group A were significantly higher compared those in Group B ( P =0.015, P =0.028, P =0.010). The median overall survival(OS) and progression-free survival(PFS) of group A were 32 months and 10 months, respectively. The median OS of group B was not reached, and the median PFS was 32 months. The 3-year OS rates of patients in group A and group B were 46.7% and 62.2%, respectively ( P =0.021), and the 3-year PFS were 29.2% and 42.5%, respectively ( P =0.033). There were no significant differences in OS and PFS between group A1 and group A2, or between group B1 and group B2 ( P >0.05). Multivariate COX survival analysis showed that the plasma cell percentage ≥33.5%（HR=1.253, 95%CI : 0.580-2.889, P =0.018）, age ≥65 years (HR=2.206, 95%CI : 1.170-3.510, P =0.012), lactate dehydrogenase(LDH) ≥250 U/L (HR=1.180, 95%CI : 0.621-2.398, P =0.048) and β₂-MG ≥3.5 mg/L (HR=1.507, 95%CI : 0.823-3.657, P =0.036) were independent risk factors affecting OS in MM patients. CONCLUSION MM patients with a higher plasma cell percentage (≥33.5%) at the initial diagnosis have a later disease stage, poorer OS and PFS, compared to the patients with a lower percentage(<33.5%) of plasma cells. The presence or absence of immature plasma cells has no significant impact on the survival of MM patients.

OBJECTIVE: To analyze the clinical characteristics and prognosis of patients with T-cell large granular lymphocytic leukemia (T-LGLL). METHODS: The clinical data of 7 patients with T-LGLL in Gansu Provincial Hospital from March 2016 to June 2023 were analyzed retrospectively. RESULTS: Among the 7 patients, 5 were male and 2 were female, with a median age of 51(28-83) years old. At the onset of illness, 6 cases showed symptoms of fatigue and anemia, 4 cases had enlarged lymph nodes, and 5 cases had splenomegaly. Examination showed that 4 cases were antinuclear antibody(ANA) positive, 5 cases were anemia. The median hemoglobin (Hb) level was 83(61-151) g/L, the median white blood cell count (WBC) was 5.6(2.0-8.7)×10⁹ /L, and the median percentage of lymphocytes in peripheral blood was 66.2(13.9-89.1)%. There were 3 cases with extremely active bone marrow hyperplasia, 2 cases with active hyperplasia, and 2 cases with decreased hyperplasia. There were 5 cases with mild myelofibrosis (MF-1), and 1 case with moderate myelofibrosis (MF-2). The median percentage of T cells was 64.3 (31.5-80.6)%. 5 cases showed the classic immunophenotype (CD3 ⁺ CD4^- CD8 ⁺), 6 cases were CD57 ⁺, 3 cases were TCRα/β ⁺, and 3 cases were TCRγ/δ ⁺. TCRG rearrangement was detected in 5 cases.The median follow-up time was 55(4-87) months, one patient died of heart disease, and the other 6 patients are surviving. CONCLUSION The incidence of T-LGLL is low. The initial symptoms of T-LGLL include anemia, fatigue, lymph node enlargement, splenomegaly, and higher percentage of lymphocytes in peripheral blood, the percentage of abnormal T cells in bone marrow was significantly increased. Analysis of flow cytometric immunophenotyping, TCR gene rearrangement, and hot spot genes such as STAT3 and STAT5b, can improve the diagnostic accuracy.

AIM: To investigate the effect of intense pulsed light(IPL)combined with meibomian gland massage in patients with meibomian gland dysfunction(MGD)related dry eye.METHODS: Retrospectively selected 300 cases(300 right eyes)that diagnosed as MGD-related dry eye and treated in our hospital from October 2021 to October 2023, and they were divided into two groups according to the treatment modalities: 150 cases(150 eyes)in the control group were treated with meibomian gland massage, and 150 cases(150 eyes)in the observation group were treated with combined IPL. The efficacy of the two groups was compared, as well as the changes in tear film stability indexes [tear film break-up time(BUT), Schirmer I test(SIT)], ocular surface disease index(OSDI)scores, tear film lipid layer thickness(LLT), mean objective scattering index(OSI), and the levels of inflammatory factors in the tear fluid [interleukin-10(IL-10)and IL-6].RESULTS: There was a difference in efficacy between the two groups of patients after treatment(88% vs 74%, P=0.002). At 8 wk after treatment, OSDI score, OSI, and tear IL-6 levels decreased, while BUT, SIt, LLT, and tear IL-10 levels increased in the two groups, and the observation group was better than the control group(all P<0.05).CONCLUSION: IPL combined with meibomian gland massage for the treatment of dry eye patients with MGD is therapeutically effective, improving corneal stability and LLT, and reducing levels of OSI and inflammatory factors.

Objective To observe the cage subsidence after oblique lateral interbody fusion(OLIF)for lumbar spondylo-sis,summarize the characteristics of the cage subsidence,analyze causes,and propose preventive measures.Methods The data of 144 patients of lumbar spine lesions admitted to our hospital from October 2015 to December 2018 were retrospectively ana-lyzed.There were 43 males and 101 females,and the age ranged from 20 to 81 years old,with an average of(60.90±10.06)years old.Disease types:17 patients of lumbar intervertebral disc degenerative disease,12 patients of giant lumbar disc hernia-tion,5 patients of discogenic low back pain,33 patients of lumbar spinal stenosis,26 patients of lumbar degenerative spondy-lolisthesis,28 patients of lumbar spondylolisthesis with spondylolisthesis,11 patients of adjacent vertebral disease after lumbar internal fixation,7 patients of primary spondylitis in the inflammatory outcome stage,and 5 patients of lumbar degenerative scoliosis.Preoperative dual-energy X-ray bone mineral density examination showed 57 patients of osteopenia or osteoporosis,and 87 patients of normal bone density.The number of fusion segments:124 patients of single-segment,11 patients of two-seg-ment,8 patients of three-segment,four-segment 1 patient.There were 40 patients treated by stand-alone OLIF,and 104 patients by OLIF combined with posterior pedicle screw.Observed the occurrence of fusion cage settlement after operation,conducted monofactor analysis on possible risk factors,and observed the influence of fusion cage settlement on clinical results.Results All operations were successfully completed,the median operation time was 99 min,and the median intraoperative blood loss was 106 ml.Intraoperative endplate injury occurred in 30 patients and vertebral fracture occurred in 5 patients.The mean follow-up was(14.57±7.14)months from 6 to 30 months.During the follow-up,except for the patients of primary lumbar interstitial in-flammation and some patients of lumbar spondylolisthesis with spondylolisthesis,the others all had different degrees of cage subsidence.Cage subsidence classification:119 patients were normal subsidence,and 25 patients were abnormal subsidence(23 patients were grade Ⅰ,and 2 patients were grade Ⅱ).There was no loosening or rupture of the pedicle screw system.The height of the intervertebral space recovered from the preoperative average(9.48±1.84)mm to the postoperative average(12.65±2.03)mm,and the average(10.51±1.81)mm at the last follow-up.There were statistical differences between postop-erative and preoperative,and between the last follow-up and postoperative.The interbody fusion rate was 94.4％.The low back pain VAS decreased from the preoperative average(6.55±2.2 9)to the last follow-up(1.40±0.82),and there was statistically significant different.The leg pain VAS decreased from the preoperative average(4.72±1.49)to the final follow-up(0.60± 0.03),and the difference was statistically significant(t=9.13,P＜0.000 1).The ODI index recovered from the preoperative av-erage(38.50±6.98)％to the latest follow-up(11.30±3.27)％,and there was statistically significant different.The complication rate was 31.3％(45/144),and the reoperation rate was 9.72％(14/144).Among them,8 patients were reoperated due to fusion cage subsidence or displacement,accounting for 57.14％(8/14)of reoperation.The fusion cage subsidence in this group had obvious characteristics.The monofactor analysis showed that the number of abnormal subsidence patients in the osteopenia or osteoporosis group,Stand-alone OLIF group,2 or more segments fusion group,and endplate injury group was higher than that in the normal bone mass group,OLIF combined with pedicle screw fixation group,single segment fusion group,and no endplate injury group,and the comparison had statistical differences.Conclusion Cage subsidence is a common phenomenon after 0-LIF surgery.Preoperative osteopenia or osteoporosis,Stand-alone OLIF,2 or more segments of fusion and intraoperative end-plate injury may be important factors for postoperative fusion cage subsidence.Although there is no significant correlation be-tween the degree of cage subsidence and clinical symptoms,there is a risk of cage migration,and prevention needs to be strengthened to reduce serious complications caused by fusion of cage subsidence,including reoperation.

Objective To investigate the distribution and clinical characteristics of TCM syndromes in infertility patients with autoimmune thyroiditis(AIT).Methods By referring to the relevant literature on the distribution of TCM syndromes of AIT and infertility in women of childbearing age,the TCM Syndromes Survey of Infertility Patients with Autoimmune Thyroiditis was formulated.256 cases of infertility patients with AIT who underwent in vitro fertilization-embryo transfer(IVF-ET)at the Reproductive Center of The First Affiliated Hospital of University of Science and Technology of China from June 2019 to December 2020 were retrospectively analyzed.The data of basic information,TCM syndromes,basic thyroid-stimulating hormone(TSH),thyroid peroxidase antibody(TPO-Ab)and thyroglobulin antibody(TG-Ab)were collected.By means of frequency analysis and systematic cluster analysis,the distribution regularity of TCM syndromes in infertility patients with AIT were concluded.Results After analysis,the following 5 common syndrome elements were obtained,namely,qi deficiency,liver depression,spleen deficiency,kidney deficiency and blood stasis.In addition,it was concluded that this disease was more common in complex syndromes.Through systematic clustering analysis,main TCM syndromes of this disease were obtained,which were qi deficiency and liver depression syndrome(69 cases,26.9%),spleen and kidney deficiency syndrome(45 cases,17.6%),spleen qi deficiency syndrome(38 cases,14.8%),qi deficiency and blood stasis syndrome(36 cases,14.1%),kidney deficiency and liver depression syndrome(32 cases,12.5%)and other syndrome types(36 cases,14.1%).The basic TSH level was higher in patients with qi deficiency and liver depression syndrome,spleen qi deficiency syndrome,qi deficiency and blood stasis syndrome than other syndrome types,with statistical significance(P<0.05).There was no significant difference in TPO-Ab and TG-Ab titers among different syndromes(P>0.05).Conclusion TCM syndromes of infertility patients with AIT can be clustered into qi deficiency and liver depression syndrome,spleen and kidney deficiency syndrome,spleen qi deficiency syndrome,qi deficiency and blood stasis syndrome,kidney deficiency and liver depression syndrome and other syndrome.The main element of syndrome is qi deficiency,and the pathological sites involved spleen,kidney and liver.Stasis blood is a main pathological product.It is required to pay close attention to the thyroid function in AIT patients with qi deficiency.

BACKGROUND:Up to date,there is seldom research about the correlation between the harmonious alignment degree of lumbar lordosis and pelvic incidence and the improvement of postoperative clinical symptoms in patients with lumbar stenosis fusion. OBJECTIVE:To investigate the harmonious alignment degree of lumbar lordosis and pelvic incidence in patients with lumbar spinal stenosis and fusion,and compare the differences of spinal and pelvic sagittal parameters and clinical outcomes among different harmonious alignment degrees. METHODS:The medical records of 110 patients with lumbar spinal stenosis(48 males and 62 females,aged 57±11 years)who were treated with posterior lumbar laminar decompression and internal fixation in the Department of Spinal Surgery,Tianjin Union Medical Center from December 2019 to December 2021 were retrospectively analyzed.The postoperative follow-up was more than 1 year.According to the harmonious alignment degree of lumbar lordosis and pelvic incidence,they were divided into two groups:Group A(n=47)(pelvic incidence-lumbar lordosis>10°)and group B(n=63)(pelvic incidence-lumbar lordosis≤10°).The changes of clinical scores(low back pain visual analog scale score and Oswestry disability index)and spinal and pelvic sagittal parameters before and after surgery were compared between the two groups.The correlation between clinical symptom improvement and spinal and pelvic imaging parameters was analyzed. RESULTS AND CONCLUSION:(1)There were no significant differences in preoperative pelvic sagittal parameters and clinical function between the two groups(P>0.05).(2)There were no significant differences in operation time and blood loss between the two groups(P>0.05).(3)At the last postoperative follow-up,the visual analog scale score and Oswestry disability index in group B were significantly improved compared with group A(P=0.000,P=0.005).Lumbar lordosis and sacral slope were also significantly improved(P=0.000,P<0.05),and pelvic tilt was more significantly recovered(P=0.000).(4)Pearson correlation coefficient method results showed that the improvement of visual analog scale score of low back pain was significantly correlated with the improvement of pelvic tilt(r=0.209,P=0.008),lumbar lordosis(r=-0.133,P=0.021)and sacral slope(r=-0.156,P=0.031).Pelvic tilt was significantly correlated with Oswestry disability index(r=0.196,P=0.014).(5)It is concluded that reconstructed lumbar lordosis and reduced pelvic tilt for the harmonious alignment(pelvic incidence-lumbar lordosis≤10°)can effectively improve the clinical symptoms of patients.
