Radiopharmaceuticals operate by combining radionuclides with carriers. The radiation energy emitted by radionuclides is utilized to selectively irradiate diseased tissues while minimizing damage to healthy tissues. In comparison to external beam radiation therapy, radionuclide drugs demonstrate research potential due to their biological targeting capabilities and reduced normal tissue toxicity. This article reviews the applications and research progress of radiopharmaceuticals in cancer treatment. Several key radionuclides are examined, including ²²³Ra, ⁹⁰Y, Lutetium-177 (¹⁷⁷Lu), ²¹²Pb, and Actinium-225 (²²⁵Ac). It also explores the current development trends of radiopharmaceuticals, encompassing the introduction of novel radionuclides, advancements in imaging technologies, integrated diagnosis and treatment approaches, and equipment-medication combinations. We review the progress in the development of new treatments, such as neutron capture therapy, proton therapy, and heavy ion therapy. Furthermore, we examine the challenges and breakthroughs associated with the clinical translation of radiopharmaceuticals and provide recommendations for the research and development of novel radionuclide drugs.

Diabetic peripheral neuropathy (DPN) is the common chronic complication of diabetes, which can lead to foot ulcers, gangrene, and amputation in severe cases, seriously affecting their quality of life. DPN belongs to the category of "arthralgia", "hemorrhoids" and other categories of TCM, and the main pathogenesis is the deficiency of qi and blood, yin and yang, and the obstruction of the meridians by phlegm and stasis. Clinically, DPN is more common with qi deficiency and blood stasis syndrome. Based on the theory of "qi meridian constant communication" in the Huang Di Nei Jing, this article proposed that for patients with DPN with qi deficiency and blood stasis syndrome, the treatment should be based on the principle of "invigorating qi and activating blood circulation, dissolving stasis and arthralgia", so that the patients' qi meridian can be accessible, delay the disease progression, and provide reference for the TCM treatment of DPN.

Objective:To explore the treatment options for patients with osteoporotic thoracolumbar injury classification and severity score (OTLICS) of 4 points following acute symptomatic osteoporotic vertebral compression fracture (OVCF) .Methods:A retrospective case-control study was conducted to analyze the clinical data of 108 patients with acute symptomatic OVCF admitted to Honghui Hospital, Xi'an Jiaotong University Faculty of Medicine from February 2016 to February 2018. There were 21 males and 87 females, aged 55-92 years [(71.6±5.3)years]. All patients had OTLICS score of 4 points. Of all, 76 patients were treated operatively (surgery group) and 32 patients were treated non-operatively (non-surgery group). The visual analogue scale (VAS), Oswestry disability index (ODI) and quality of life score (SF-36) were compared between the two groups before treatment, at 1 week, 3 months, 6 months after treatment, and at the last follow-up. The recovery of the injured vertebrae before and after treatment (Cobb angle of the injured vertebra, relative height of the anterior edge of the injured vertebrae), adjacent vertebral body fractures, and complications were compared between the two groups.Results:All patients were followed up for 12-18 months [(13.4±4.2)months]. At 1 week, 3 months and 6 months after treatment, the VAS in surgery group [(3.5±1.0)points, (2.1±0.6)points, (2.0±0.4)points] was better than that in non-surgery group [(6.4±1.7)points, (5.3±1.5)points, (3.3±0.6)points] ( P<0.05), the ODI in surgery group [(45.8±10.3)points, (35.3±8.6)points, (26.5±7.1)points] was better than that in non-surgery group [(65.7±12.1)points, (58.3±10.7)points, (45.6±9.3)points] ( P<0.05), the SF-36 in surgery group [(82.8±1.4)points, (85.0±1.5)points, (88.0±1.3)points] was better than that in non-surgery group [(80.4±1.3)points, (81.5±1.4)points, (85.6±1.1)points] ( P<0.05). At the last follow-up, there were no significant differences in VAS, ODI and SF-36 between the two groups ( P>0.05). At 3 months, 6 months and the last follow-up, the Cobb angle in surgery group [(18.3±3.9)°, (17.5±3.0)°, (17.8±1.6)°] was better than that in non-surgery group [(22.4±2.2)°, (22.5±1.7)°, (22.1±1.3)°] ( P<0.05), and the relative height of the anterior edge of the injured vertebra in surgery group [(75.4±8.6)%, (76.6±8.6)%, (75.2±8.3)%] was better than that in non-surgery group [(63.5±7.6)%, (65.2±7.4)%, (62.8±7.2)%] ( P<0.05). The adjacent vertebral fractures occurred in 6 patients (8%) in surgery group, and in 2 patients (6%)in non-surgey group ( P>0.05). Postoperative complications occurred in 8 patients (11%) in surgery group, and occurred in 6 patients (19%) in non-surgery group ( P>0.05). Conclusion:When applying the OTLICS scoring system to treat acute symptomatic OVCF, patients with OTLICS score of 4 points should be promptly treated with operatively, which can quick relieve pain, correct deformities promote functional recovery, and improve quality of life.

Objective:To compare the clinical efficacy of percutaneous vertebroplasty (PVP) and non-surgical treatment of patients with type I fracture according to the acute symptomatic osteoporotic thoracolumbar fracture (ASOTLF) classification.Methods:A retrospective case-control study was used to analyze the clinical data of 115 patients with ASOTLF admitted to Honghui Hospital of Xi'an Jiaotong University from January 2015 to December 2018. There were 48 males and 67 females, aged 65-92 years [(75.3±8.5)years]. According to clinical symptoms and imaging characteristics, all patients were identified with type I fracture according to the ASOTLF classification. Injury segments were at T 6 to T 10 in 10 patients, at T 11 in 15, at T 12 in 26, at L 1 in 34, ay L 2 in 18, at L 3 in 7, and at L 4 in 5. A total of 73 patients received PVP combined with anti-osteoporosis treatment (surgery group), and 42 patients received non-surgery combined anti-osteoporosis treatment (non-surgery group). Before treatment, at 1 day, 1 month, 3 months, 6 months after treatment, and at the last follow-up, the visual analogue scale (VAS) was used to assess the pain, the Roland Morris Disability (RMD) score to assess the spinal function, and the Quality of Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO) score to evaluate the quality of life. The bone mineral density was compared between groups before treatment and at 1 year after treatment. The complications were observed as well. Results:All patients were followed up for 12-18 months [(13.2±4.6)months]. At 1 day, 1 month, and 3 months after treatment, the VAS in surgery group [(3.9±0.6)points, (3.3±0.6)points, (2.9±0.3)points] was significantly lower than that in non-surgery group [(6.0±0.7)points, (5.0±0.8)points, (4.2±1.0)points, respectively] (all P<0.05); the RMD score in surgery group [(15.2±0.7)points, (12.6±0.7)points, (10.6±0.7)points] was significantly lower than that in non-surgery group [(16.4±0.8)points, (14.6±0.8)points, (12.7±0.6)points, respectively] (all P<0.05). At 1 day and 1 month after treatment, the QUALEFFO score in surgery group [(46.0±1.1)points, (41.4±0.8)points] was lower than that in non-surgery group [(50.3±0.8)points, (44.7±1.2)points] (all P<0.05). There was no statistically significant difference between the two groups at other time points of the above indicators ( P>0.05). At 1 year after treatment, the bone mineral density in surgery group was (-3.0±0.9)SD, and was (-2.8±1.1)SD in non-surgery group ( P>0.05). There was no significant difference in the incidence of complications between surgery group [37%(27/73)] and non-surgery group [33%(14/42)] ( P>0.05). Conclusion:For patients with ASOTLF type I fracture, PVP and non-surgical treatment has similar effects in anti-osteoporosis and occurrence of complications, but the PVP is superior to non-surgical treatment in early pain relief, spinal function improvement and quality of life.

Objective:To analyze the effectiveness and immunogenicity of enterovirus-A71(EV-A71) vaccine in immunization program.Methods:A cohort study was conducted in immunization clinics in Jing’an district in Shanghai from October to December 2017. Children who received EV-A71 vaccine based on a 2-dose schedule (on day 0 and day 30) were enrolled as vaccine group and those who received no EV-A71 vaccine were enrolled as control group. After 1-year follow-up, the effectiveness and neutralizing antibody level and the positive results of antibody immunogenicity in vaccine group were analyzed.Results:A total of 3 018 children aged 8-20 months were enrolled, in whom 1 211 were in vaccine group and 1 807 were in control group. The vaccine effectiveness was 100% against EV-A71-associated hand, foot, and mouth disease (HFMD) indicated by 1 year follow-up (95 %CI: -66.99%-100.00%). The geometric mean titer of neutralizing antibody (GMT) was 41.76 (95 %CI: 35.60-49.34) at day 60 and 28.44(95 %CI: 23.59-34.54) at day 365 in 124 children in vaccine group. Conclusions:In children, EV-A71 vaccine elicited EV-A71-specific immune response. Less EV-A71-associated HFMD cases have been observed, further observation is needed.

Objective To establish and assess the new method of APTT assay based on the combinations of Mg2+and Ca2+for lupus anticoagulants(LA)measurements.Methods This prospective study included 309 trisodium citrate anticoagulated plasma samples from 244 random patients and 65 patients with different autoimmune diseases(AID)to establish and assess the method of LA measurement, respectively.Final concentrations of 0,2.0, 4.0, 8.0,16.0 mmol/L Mg2+were added into 25 mmol/L Ca2+solution, and Actin reagent was used to measured plasma APTT of 94 patients.The applied concentration of Mg2+-Ca2+solution was confirmed through the special and significant alteration of APTT from LA-positive and -negative plasma observed in the presence of Mg 2+(test solution).Based on Actin reagent use,the test solution and 25 mmol/L Ca2+solution were applied to measure APTT of patients and normal individuals, respectively, and the ratio of Mg2+-Ca2+-APTT to Ca2+-APTT(Mg2+-Ca2+-APTT indices)and normalized Mg2+-Ca2+-APTT indices(NAR)were calculated, respectively.Mixed plasma NAR was measured,and CV%was calculated to evaluate the repeatability and stability of Mg 2+-Ca2+-APTT method.APTT of 150 patients was measured with the test solution and Actin reagent to calculate Mg 2+-Ca2+-APTT indices, and normalized LA ratio was determined with dRVVT method.The applicability of Mg2+-Ca2+-APTT assay was assessed through comparisons of the results from the two methods.Finally, NAR and NLR of 65 patients with AID(including 26 SLE patients)were measured with Mg2+-Ca2+-APTT assay and dRVVT method, respectively, and ROC curve was also used to assess the efficacy of the two methods for LA measurements.Results In all LA-negative plasma,APTT increased from 28.1 ±4.5 s to 61.2 ±7.9 s in normal APTT group,47.2 ±8.9 s to 97.5 ±10.3 s in increased APTT group,and 27.6 ± 5.1 s to 61.2 ±7.9 s in ACA-positive group when Mg2+increased from 0 to 8 mmol/L in Mg2+-Ca2+solution(F=34.12, 38.9 and 28.35,P<0.01).Following increased Mg2+concentration, APTT shortened from 0 to 4.0 mmol/L, but simultaneously prolonged from 4.0 to 16.0 mmol/L in LA-positive plasma with prolonged or normal APTT(F=31.55 and 39.51, P<0.01), and APTT was significantly higher in 8.0 mmol/L than that in 4.0 mmol/L(P<0.001).The test concentration of Mg 2+/Ca2+solution was 4.0 mmol/L.The within, inter-day CV% of NAR was 1.39%,2.30%, and 3.44%, respectively. According to the judging criteria of <0.966 and >1.034 of Mg2+/Ca2+indices, there was 141 patients with increased indices and NLR <1.20, and 9 patients with decreased ones and NLR≥1.20 in all 150 patients.The area under ROC curve of NAR and NLR for LA detection was 0.913(95%CI:0.848-0.978) and 0.892(95%CI:0.817-0.966), respectively, and the cut-off value was 0.87 and 1.13, respectively. The sensitivity and specificity of NAR(85% and 77%)was higher than that of NLR(81% and 74%), respectively.The accordant rate of positive,negative,and total results between NAR and NLR was 94.4%, 98.5%,and 98%,respectively.Conclusion The method of APTT assay based on Mg2+combining Ca2+for LA measurements is feasible,and can be used to detect plasma LA of patients.

Objective To investigate the influences of psychological rehabilitation nursing on immune function in post stroke depression patients.Methods A total of 80 elderly patients with post stroke depression were recruited from the inpatients in geriatric neurology department at Tianjin Medical University General Hospital.All patients were divided into two groups:the control group received only conventional and auxiliary exercise therapy for 3 months; rehabilitation group received psychological rehabilitation nursing added to the above therapy for 3 months.Barthel indexes,Hamilton Depression Scale (HAMD) scores and immune function were detected at recruit and three months after treatment.Results There were no statistically significant differences in clinical data between the rehabilitation group and control group (all P＞0.05).There were no statistically significant differences in Barthel indexes,Hamilton Depression Scale (HAMD) scores and immune function between rehabilitation group and control group before treatment (all P＞ 0.05).Compared with control group,the rehabilitation group showed that the Barthel Indexes were increased (P=0.000),Hamilton Depression Sale (HAMD) scores were decreased (P=0.000),the levels of T lymphocyte subpopulation (P＜ 0.05) and immunoglobulin (P＜ 0.01) were increased after three months treatment.Conclusions The combination treatment of psychological rehabilitation nursing,auxiliary exercise and drug are helpful to recover immune function and improve the quality of life in patients with post stroke depression.

OBJECTIVETo standardize the experimental procedure of the gene test for autosomal dominant cerebellar ataxias (ADCA), and provide the basis for quantitative criteria of the dynamic mutation of spinocerebellar ataxia (SCA) genes in Chinese population.

METHODSGenotyping of the dynamic mutation loci of the SCA1, SCA2, SCA3, SCA6 and SCA7 genes was performed, using florescence PCR-capillary electrophoresis followed by DNA sequencing, to investigate the variation range of copy number of CAG tandem repeat of the genes in 263 probands of ADCA pedigrees and 261 non-related normal controls. Based on the sequencing result, the bias of the CAG copy number estimation using capillary electrophoresis with different DNA controls was compared to analyze the technical detailes of the electrophresis method in testing the dynamic mutation sites.

RESULTSPCR products containing dynamic mutation loci of the SCA genes showed significantly higher mobility than that of molecular weigh marker with relatively balanced GC content. This was particularly obvious in the SCA2, SCA 6 and SCA7 genes whereas the deviation of copy number could be corrected to +/-1 when known CAG copy number fragments were used as controls. The mobility of PCR products was primarily related to the copy number of CAG repeat when the fragments contained normal CAG repeat. In the 263 ADCA pedigrees, 6 (2.28%) carried SCA1 gene mutation, 8 (3.04%) had SCA2 mutation and 81 (30.80%) harbored SCA3 mutation. The gene mutation of SCA6 and SCA7 was not found. The normal variation range of the CAG repeat was 17-36 copies in SCA1 gene, 13-30 copies in SCA2, 14-39 copies in SCA3, 6-16 copies in SCA6 and 6-13 copies in SCA7. The heterozygosity was 76.1%, 17.7%, 74.4%, 72.1% and 41.3%, respectively. The mutation range of the CAG repeat was 49-56 copies in SCA1 gene, 36-41 copies in SCA2, 59-81 copies in SCA3. Neither homozygous mutation of an SCA gene nor double heterozygous mutation of the SCA genes was observed in the study.

CONCLUSIONThe copy number of the CAG repeat in SCA genes could be calculated accurately based on the result of florescence PCR-capillary electrophoresis when limited amount of known repeat copy number controls were used. Our result supported that the notion that SCA3 gene mutation was the most common cause for ADCA, and the obtained data would be helpful for establishing quantitative criteria of the dynamic mutation of the SCA genes in Chinese.
