Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

OBJECTIVE: To evaluate the efficacy and safety of Cidan Capsule combined with adjuvant transarterial chemoembolization (TACE) in patients with a high risk of early recurrence after curative resection of hepatocellular carcinoma (HCC). METHODS: A multicenter, randomized controlled trial was conducted in patients with high-risk recurrence factors after curative resection of HCC from 9 medical centers between July 2014 and July 2018. Totally 249 patients were randomly assigned to TACE with or without Cidan Capsule administration groups by stratified block in a 1:1 ratio. Postoperative adjuvant TACE was given 4-5 weeks after hepatic resection in both groups. Additionally, 125 patients in the TACE plus Cidan group were administrated Cidan Capsule (0.27 g/capsule, 5 capsules every time, 4 times a day) for 6 months with a 24-month follow-up. Primary endpoints included disease-free survival (DFS) and tumor recurrence rate (TRR). Secondary endpoint was overall survival (OS). Any drug-related adverse events (AEs) were observed and recorded. RESULTS: As the data cutoff in July 9th, 2018, the median DFS was not reached in the TACE plus Cidan group and 234.0 days in the TACE group (hazard ratio, 0.420, 95% confidence interval, 0.290-0.608; P<0.01). The 1- and 2-year TRR in the TACE plus Cidan and TACE groups were 31.5%, 37.1%, and 60.8%, 63.4%, respectively (P<0.01). Median OS was not reached in both groups. The 1- and 2-year OS rates in TACE plus Cidan and TACE groups were 98.4%, 98.4%, and 89.5%, 87.9%, respectively (P<0.05). The most common grade 3-4 AEs included fatigue, abdominal pain, lumbar pain, and nausea. One serious AE was reported in 1 patient in the TACE plus Cidan group, the death was due to retroperitoneal mass hemorrhage and hemorrhagic shock, and was not related to study drug. CONCLUSIONS Cidan Capsule in combination with TACE can reduce the incidence of early recurrence in HCC patients at high-risk of recurrence after radical hepatectomy and may be an appropriate option in postoperative anti-recurrence treatment.

Nitrogen fertilizer has been the long-lasting crucial component in cultivation of Chinese materia medica(CMM) and crops for its profound effects on enhancing the productivity. In consideration of its role in better production, intensive and excessive application of N fertilizer is often found in CMM cultivation. Therefore, firstly, this review summarized various concentrations of N application with regards to different CMM and districts from the literatures published in the last two decades. The recommended concentration of nitrogen application of forty seven CMM species were covered in this review. We found that the optimum rates of nitrogen fertili-zer for different medicinal plants species were varied in the range between 0-1 035.55 kg·hm~(-2). Most of the optimum rates of nitrogen fertilizer for CMM in published researches fell between 100-199 kg·hm~(-2). The optimum rate of nitrogen fertilizer is not only related to amount of nitrogen required for different medicinal plants but also to soil fertilities of different fields. In addition, we outlined the diffe-rent effects of proper and excessive nitrogen deposition on yield of CMM. Proper nitrogen deposition benefits the yield of CMM, howe-ver, excessive nitrogen use accounts for a decrease in CMM yield. We elucidated that nutritional content, water use efficiencies, and photosynthesis capacity were major influencing factors. Researches showed that proper nitrogen fertilizer could promote the water use efficiencies of plants and boost photosynthesis. Consequently, the yield of CMM can be enhanced after nitrogen deposition. However, negative effects of nitrogen fertilizer were also found on plant including producing toxic substances to the soil and causing severe pest damages. Lastly we analyzed the impact of N fertilizer application on secondary metabolites which accounts for a large part of active pharmaceutical ingredients of CMM. It usually caused an increase in nitrogen-containing secondary metabolites content and a decrease in non-nitrogen-containing secondary metabolites content respectively. The potential underlying mechanisms are the different synthetic pathways of these metabolites and the plant nutritional status. Synthesis of non-nitrogen-containing secondary metabolites like phenols can be inhibited after nitrogen application because of the competition of the same precursor substances between metabolites synthesis and plant growth. To sum up, impacts and mechanisms of nitrogen fertilizer on yield and quality enhancement of CMM were discussed in this review. Negative effects of excessive nitrogen application on CMM should be paid special attention in CMM cultivation and prescription fertilization based on the field soil quality is strongly recommended. Overall, this review aims to provides insights on improving the proper application of N fertilizer in the cultivation of CMM.

Nitrogen fertilizers play an important role in the regulation of plant stress resistance. Impacts of nitrogen fertilizers on abiotic stress resistance and biotic stress resistance of Chinese materia medica(CMM) were summarized in this study. Adequate nitrogen application improves the abiotic stress resistance and weed resistance of CMM, however adverse effect appears when excess nitrogen is used. Generally, pest resistance decreases along with nitrogen deposition, while effects of nitrogen application on disease resistance vary with different diseases. Mechanisms underlying the impact of nitrogen fertilizers on plant stress resistance were also elucidated in this study from three aspects including physical defense mechanisms, biochemistry mechanisms and molecular defense mechanisms. Nitrogen availability modulates physical barrier of CMM like plant growth, formation of lignin and wax cuticle, and density of stomata. Growth of CMM promoted by nitrogen fertilizer may cause some decrease in pest resistance of CMM due to an increase in hiding places for pest along with plant growth. High ambient humidity caused by excessive plant growth facilitates the growth and development of CMM pathogen. Nitrogen application can also interfere with the accumulation of lignin in CMM which makes CMM more vulnerable to pest and pathogen attack. Stomatal closing delays due to nitrogen application is also a causal factor of increasing pathogen infection after nitrogen deposition. Biochemical defenses of plants are mainly achieved through nutrient elements, secondary metabolites, defense-related enzymes and proteins. Nutritional level of CMM and various antioxidant enzymes and resistance-related protein activities are elevated along with nitrogen deposition. These antioxidant enzymes can reduce the damage of reactive oxygen species content produced by plant in response to adversity and therefore enhance stress resistance of CMM. Researches showed that nitrogen application could also cause an increase in nitrogen-containing secondary metabolites content and a decrease in non-nitrogen-containing secondary metabolites content respectively. Nitrogen-mediated molecular defense mechanisms includes multiple plant hormones and nitric oxide signals. Plant hormones related to plant defense like salicylic acid, jasmonic acid and abscisic acid can be modulated by nitrogen application. Negative effect of nitrogen deposition was found on salicylic acid accumulation and the expression of related plant disease resistance genes. However, jasmonic acid level can be elevated by nitrogen. Nitric oxide signals constitute an important part of nitrogen mediated defense mechanisms. Nitric oxide signaling is related to many aspects of plant immunity. The roles of nitrogen fertilizers in CMM stress resistance are complex and may vary with different CMM varieties and environments. Further studies are urgently needed to provide a comprehensive understanding of how to improve stress resistance of CMM by using fertilizers.

OBJECTIVE: To explore the expression of Blimp1, ATF4 and CHOP in bone marrow mononuclear cells from patients with multiple myeloma as well as the effect of aspirin on their expression. METHODS: Sixty untreated patients with multiple myeloma and 30 patients with relatively normal bone marrow were selected. Mononuclear cells from the bone marrow fluid were separated using Ficoll separation solution. CD138 plasma cells were sorted by immunomagnetic beads method. RT-PCR was used to detect the expression levels of Blimp1, ATF4 and CHOP mRNA in U266 cells cultured in vitro. The cells were divided into blank control group, negative control group (no-loaded virus transfection) and positive experimental group [LV-Blimp1-RNAi (40051-2) transfection] by lentivirus transfection. RT-PCR was used to detect the expression of Blimp1, ATF4 and CHOP mRNA in cells of different groups. U266 cells were stimulated in vitro with different concentrations of aspirin solution (0, 0.5 mmol/L, 2.5 mmol/L, 5.0 mmol/L) for 24, 48 h and 72 h, respectively. The ability of cell proliferation in different groups was measured by CCK-8. U266 cells were stimulated with different concentrations of aspirin for 48 hours. And the mRNA expression of Blimp1, ATF4 and CHOP was detected by RT-PCR. RESULTS: Compared with plasma cells in normal group, the expression of Blimp1 mRNA in CD138 plasma cells of MM patients significantly increased (8.040±1.878), and the mRNA expression levels of ATF4 and CHOP significantly decreased (0.735±0.089; 0.837±0.062) (P＜0.05). U266 cells were cultured in vitro. Compared with the blank control group and the negative control group, the mRNA expression level of Blimp in the positive experimental group was significantly down-regulated after infection with LV-Blimp1-RNAi (40051-2) lentiviral expression vector (0.637±0.021). ATF4 and CHOP mRNA expression levels were significantly increased (1.452 ± 0.027; 1.721 ± 0.038) (P＜0.05). The proliferation of U266 cells decreased after stimulation with aspirin. In the range of (0.5-5) mmol/L, aspirin could significantly inhibit the proliferation of U266 cells. The inhibition effect of aspirin was increased along with prolongation of time and increase of concentrations. After aspirin stimulation of different concentrations for 48 hours, the expression level of Blimp1 in U266 cells decreased with increasing of drug concentration, while the expression levels of ATF4 and CHOP increased with increasing of drug concentration. CONCLUSION Inhibition of Blimp1 expression in multiple myeloma cells can promote the expression of ATF4 and CHOP. Aspirin can inhibit the proliferation activity of myeloma cells by down-regulating Blimp1 expression in myeloma cells and up-regulating ATF4 and CHOP expression, therefore plays an anti-tumor rote.

Objective:To observe the effect of Lafosse I subscapularis lesion repair on the reconstruction of anterosuperior rotator cufftear.Methods:A retrospective analysis was performed on patients who underwent surgical treatment of the supraspinatus torn combined with Lafosse I subscapularis lesion from January 2016 to October 2017. It was divided into two groups according to the subscapularis lesion was repaired or not. There were 16 cases in non-repaired group, 7 males and 9 females, aged from 48 to 75 years (average, 59.3 years). In this group, supraspinatus repair and subscapularis debridement with no repair were done. There were 13 cases in repaired group, 5 males and 8 females, aged from 45 to 72 years (average, 57.2 years). In this group, both supraspinatus and subscapularis were repaired. MRI was performed at last follow-up. The pain analogue scale (VAS), American Shoulder & Elbow Surgeons (ASES) score, Constant-Murley score and range of motion (ROM) were recorded at the last follow-up. Patients' satisfaction was recorded.Results:Twenty-nine patients had been followed up. Patients in non-repaired group were followed up 15.9±3.9 months (range 10-22 months), and patients in repaired group were followed up 16.9±3.4 months (range 10-21 months). At the last follow-up, VAS, ASES score, and Constant-Murley score of non-repaired group were 1.1±1.1, 88.4±4.0 and 85.9±3.2 respectively. VAS, ASES score, and Constant-Murley score of repaired group were 0.9±1.1, 89.6±2.9 and 87.5±2.6 respectively. VAS ( t=0.342, P=0.735), ASES score ( t=-0.941, P=0.355) and Constant-Murley score ( t=-1.392, P=0.175) showed no significant difference between non-repaired group and repaired group. At the last follow-up, forward flexion of affected shoulder in non-repaired group was 150.3°±17.3°, external rotation was 41.6°±16.0°, and internal rotation was L 2 level; Forward flexion in repaired group was 148.1°±16.3°, external rotation was 43.9°±9.2°, and internal rotation was L 1 level, which were improved significantly compared with those pre-operation. Forward flexion, external rotation, and internal rotation showed no statistically significant difference between non-repaired group and repaired group. 3 patients were found to have rotator cuff re-tear by MR examination. The re-tear rate was 10.34% (3/29). There were 2 cases in non-repaired group and 1 case in repaired group. At the last follow-up, the ASES score of re-tear patients was 85.3±3.1, which was better than preoperative 41.0±5.2 ( t=12.74, P<0.001). Forward flexion 131.67°±5.8° was better than preoperative 81.7°±11.5° ( t=6.708, P<0.001). One re-tear patient (in non-repaired group) received reoperation and got pain relief. The satisfaction of non-repaired group and repaired group were 93.7% and 92.3%, respectively. Conclusion:For type I subscapularis lesion combined with supraspinatus injury, wheter type I subscapularis lesion was repaired or notdidn't affect the repair effect of the anterosuperior rotator cuff tear in short-term follow-up.

The implant survival rate was 100% (56/56) and the implant success rate was 98% (55/56), with an average missal and distal marginal bone loss of (0.04±0.11) mm/year. Veneer chipping occurred at incisal edge of 2 adjacent incisors in only one prosthesis 3 years after rehabilitation.Conclusions:Combination of digital techniques of neuromuscular system and condylar movement tracing device to assist occlusal rehabilitation based on ISFP showed a high implant success rate. The complication seldom happened. Long and stable occlusion has been observed. The clinical outcomes were favorable.

Objective: To understand the consistency of ALK Ventana-D5F3 immunohistochemistry (IHC) interpretation in Chinese lung adenocarcinoma among histopathologists from different hospitals, and to recommend solution for the problems found during the interpretation of ALK IHC in real world, with the aim of the precise selection of patients who can benefit from ALK targeted therapy. Methods: This was a multicenter and retrospective study. A total of 109 lung adenocarcinoma cases with ALK Ventana-D5F3 IHC staining were collected from 31 lung cancer centers in RATICAL research group from January to June in 2018. All cases were scanned into digital imaging with Ventana iSCANcoreo Digital Slide Scanning System and scored by 31 histopathologists from different centers according to ALK binary (positive or negative) interpretation based on its manufacturer′s protocol. The cases with high inconsistency rate were further analyzed using FISH/RT-PCR/NGS. Results: There were 49 ALK positive cases and 60 ALK negative cases, confirmed by re-evaluation by the specialist panel. Two cases (No. 2302 and No.2701) scored as positive by local hospitals were rescored as negative, and were confirmed to be negative by RT-PCR/FISH/NGS. The false interpretation rate of these two cases was 58.1% (18/31) and 48.4% (15/31), respectively. Six out of 31 (19.4%) pathologists got 100% accuracy. The minimum consistency between every two pathologists was 75.8%.At least one pathologist gave negative judgement (false negative) or positive judgement (false positive) in the 49 positive or 60 negative cases, accounted for 26.5% (13/49), 41.7% (25/60), respectively, with at least one uncertainty interpretation accounted for 31.2% (34/109). Conclusion There are certain heterogeneities and misclassifications in the real world interpretation of ALK-D5F3 IHC test, which need to be guided by the oncoming expert consensus based on the real world data.
