OBJECTIVE: To explore the relationship between spinous process deviation and lumbar disc herniation in young patients. METHODS: From March 2015 to January 2022, 30 treated young (under the age of 30) patients with lumbar disc herniation were included as the young group. In addition 30 middle-aged patients (quinquagenarian group) with lumbar disc herniation and 30 patients with non-degenerative spinal diseases (young non-degenerative group) were selected as control groups. The angle of the spinous process deviation was measured on CT and statistically analyzed by various groups. All the data were measured twice and the average value was taken and recorded. RESULTS: The average angle of spinous process deviation in the degenerative lumbar vertebra of young patients were (3.89±3.77) degrees, similar to the (3.72±2.98) degrees of quinquagenarian patients(P=0.851). The average angle of s spinous process deviation young non-degenerative group were (2.20±2.28) degrees, significantly less than young group(P=0.040). The spinous process deviation angle of the superior vertebral of the degenerative lumbar in the young group was (4.10±3.44) degrees, which similar to the (3.47±2.87) degrees in the quinquagenarian group (P=0.447). A total of 19 young patients had the opposite deviation direction of the spinous process of the degenerative lumbar vertebra and upper vertebra, while only 7 quinquagenarian patients had this condition(P=0.02). The type of lumbar disc herniation in young patients had no significant relationship with the direction of spinous process deflection of the degenerative or upper lumbar vertebra (P>0.05). CONCLUSION Spinous process deviation is a risk factor of young lumbar disc herniation patients. If the deviation directions of adjacent lumbar spinous processes are opposite, it will increase the incidence of lumbar disc herniation in young patients. There was no significant correlation between the type of disc herniation and the deviation direction of the spinous process of the degenerative or upper lumbar vertebra. People with such anatomical variation can strengthen the stability of spine and prevent lumbar disc herniation through reasonable exercise.

OBJECTIVE: To explore the short-term efficacy and adverse reactions of orelabrutinib combined with high-dose methotrexate (HD-MTX) in the first-line treatment of elderly high-risk primary central nervous system lymphoma (PCNSL), as well as the survival of patients. METHODS: Twenty-five elderly patients with high-risk primary central nervous system diffuse large B-cell lymphoma admitted to Fujian Provincial Hospital from June 2016 to June 2022 were enrolled in this study, and complete clinical data from all patients were collected retrospectively, and the cut-off for follow-up was December 2022. 15 patients had received temmozolomide combined with HD-MTX regimen for at least four cycles, sequential lenalidomide maintenance therapy, while 10 patients had received orelabrutinib combined with HD-MTX regimen for at least four cycles, sequential orelabrutinib maintenance therapy. The short-term efficacy and adverse reactions of the two groups of patients after treatment were observed. Kaplan-Meier was used to analyze the progression-free survival (PFS) and time to progression (TTP). RESULTS: The objective response rate (ORR) and 2-year median FPS of orelabrutinib combined with HD-MTX regimen group were similar to the temozolomide combined with HD-MTX regimen group (ORR: 100% vs 66.7%; 2-year median PFS: 16 months vs 15 months, P>0.05). The 2-year median TTP of the orelabrutinib+HD-MTX regimen group was better than that of the temozolomide+HD-MTX regimen group (not reached vs 12 months, P<0.05). There were no significant differences in adverse reactions such as gastrointestinal reactions, bone marrow suppression, liver and kidney damage, cardiotoxicity, pneumonia and bleeding between these two groups (P>0.05). CONCLUSION For elderly patients with high-risk PCNSL, orelabrutinib combined with HD-MTX has reliable short-term efficacy, good safety, and tolerable adverse reactions, which is worthy of clinical promotion.

OBJECTIVE: To analyze clinical response of the Rituximab-based chemotherapy and prognostic features in patients with primary gastric diffuse large B-cell lymphoma (PGDLBCL). METHODS: From June 2008 to December 2020, the data of 53 PGDLBCL patients were analyzed retrospectively. RESULTS: The median age was 46(25-77) years old in 53 patients including 35 males and 18 females. Stomachache is the most common symptom. The diagnosis were confirmed in 47 patients by endoscopic biopsy and 6 patients by surgery. Twenty-six patients had Ⅰ/Ⅱ1 stage (Lugano staging system) disease and 27 cases had II2/IV stage disease. All patients were treated with chemotherapy, including RCHOP (25/53) and R-DA-EPOCH (28/53). Complete remission rate was 79.2%（42/53）. The 3-year and 5-year overall survival (OS) rates were 77.4% and 69.8%. Univariate analysis showed that lactate dehydrogenase(LDH), Lugano stage and lesion size affected OS. Multivariate Cox regression analysis revealed that IPI score and Lugano stage were independent prognosis risk factors affecting OS. The patients in the R-DA-EPOCH group presented better survival outcomes than those in the RCHOP group with late stage (P_5-year OS=0.035). CONCLUSION Rituximab in combination with chemotherapy is the backbone of therapy for PGDLBCL. IPI score and Lugano stage are independent prognosis risk factors affecting OS of PGDLBCL. R-DA-EPOCH can be superior to R-CHOP as a first-line regimen in PGDLBCL patients with late stage.

OBJECTIVES: To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China. METHODS: A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups. RESULTS: Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05). CONCLUSIONS There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

Objective: The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population. Methods: The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models. Results: A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices). Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

In order to explore the effect of different drying methods(drying-in-the-shade, sun-drying, and hot air drying) on appearance characteristics, internal structure and composition of Belamcandae Rhizoma, so as to provide a theoretical basis for screening out suitable drying methods for primary processing. In this study, the Belamcandae Rhizoma's dynamic changes of the moisture content ratio and drying rate with different drying time under different drying methods, as well as the effects of different drying methods on the appearance, drying rate, density, ash, extractives and the contents of six flavonoids(mangiferin, tectoridin, iridin, tectorigenin, irigenin, irisflorentin) were compared. The results showed that fresh Belamcandae Rhizoma consumed the longest time to reach the water balance point by traditional dry drying in the shade, whiche was about 311 h; that by sun drying was 19.3%, which was shorter than drying in the shade; both drying curves were smoother. The section color of the sun drying samples was the closest to that of fresh samples, but the interior is full of holes, with a low density and loose structure. Hot air drying(40, 60, 80 ℃) could save about 27% to 88% of the drying time, which was greatly shorter, with less pores, a larger density and compact structure. Compared with the traditional drying method, the drying rate of hot air drying was reduced by 13.7%. Ash was affected by temperature, the drying conditions under 40 ℃ and below were not significantly different from those of conventional drying. The ash content decreased by 7.73% to 18.5% compared with conventional drying at 60,80 ℃. After conventional drying and 40 ℃ hot air drying, the contents of tectoridin and iridin(glycosides) in the samples were significantly higher than those in 60,80 ℃ hot air drying, while the contents of tectorigenin, irigenin and irisflorentin(aglycones) dried at 60 ℃ were the best. Therefore, considering comprehensive appearance characteristics and content of medicinal ingredients, traditional Chinese medicinal materials after 60 ℃ hot air drying show a solid texture, tight internal structure, good appearance, appropriate reduction of toxic parasides and higher aglycone content.

OBJECTIVE: To compare the clinical efficacy of distal radius T-plate combined with suture anchor and distal clavicle anatomical locking plate combined with suture anchor in the treatment of Neer Ⅱb distal clavicle fracture. METHODS: From June 2014 to June 2018, 42 patients with Neer Ⅱb distal clavicle fractures were retrospectively analyzed. According to different surgical methods, they were divided into the observation group (T-shaped plate combined with suture anchor) and the control group (anatomical locking plate combined with suture anchor). There were 22 patients in the observation group and 20 patients in the control group. In the observation group, there were 13 males and 9 females, aged from 22 to 70 (45.78± 14.44) years old, 12 cases on the left side and 10 cases on the right side, 8 cases of traffic accident injury and 14 cases of fall. In the control group, there were 12 males and 8 females, aged from 24 to 66 (44.17±15.58) years, 13 cases on the left side and 7 cases on the right side, 6 cases of traffic accident injuryand 14 cases of fall. The operation time, intraoperative blood loss and fracture healing time were compared between the two groups, and Constant Murley score was used to evaluate shoulder joint function. RESULTS: The patients in both groups were followed up for 18 to 24 (20.96±2.02) months. The incisions of both groups were healed at stageⅠ. The fracture ends of both groups were bony healed at the last follow up. There was no significant difference in operation time, intraoperative blood loss and fracture healing time between two groups ( CONCLUSION The two methods can obtain satisfactory results in the treatment of Neer Ⅱb distal clavicle fractures, especially suitable for patients with comminuted distal clavicle fractures or osteoporosis; the clinical effect of the treatment of NeerⅡb distal clavicle fractures with T type distal radius plate combined with suture anchor is satisfactory, which provides another feasible treatment scheme for clinic.

The present study explored the effects and its underlying mechanisms of four active fractions of Camellia nitidissima(leaf polyphenols, leaf saponins, flower polyphenols, and flower saponins in C. nitidissima) in inhibiting the proliferation and migration of non-small cell lung cancer(NSCLC) by suppressing the epidermal growth factor receptor(EGFR). MTT assay was used to detect the effect of four active fractions on the proliferation of NCI-H1975 and HCC827 cells. Wound healing assay and Transwell assay were adopted to evaluate the effect of four active fractions on the migration of NSCLC. The effect of four active fractions on the enzyme activity of EGFR was detected. Molecular docking was carried out to explore the direct action capacity and action sites between representative components of the four active fractions and EGPR. Western blot assay was employed to investigate the effect of four active fractions on the protein expression in EGFR downstream signaling pathways. The results of the MTT assay indicated that the cell viability of NCI-H1975 and HCC827 cells was significantly inhibited by four active fractions at 50, 100, 150, and 200 μg·mL~(-1) in a dose-dependent manner. Wound healing assay and Transwell assay revealed that the migration of NCI-H1975 and HCC827 cells was significantly suppressed by four active fractions. In addition, the results of the protein activity assay showed that the enzyme activity of EGFR was significantly inhibited by four active fractions. The molecular docking results confirmed that various components in four active fractions possessed strong binding activity to EGFR enzymes. Western blot assay revealed that four active fractions down-regulated the protein expression of EGFR and its downstream signaling pathways. It is concluded that the four active fractions of C. nitidissima can inhibit NSCLC. The mechanism may be related to EGFR and its downstream signaling pathways. This study provides a new scientific basis for the clinical treatment of NSCLC with active fractions of C. nitidissima, which is of reference significance for further research on the anti-tumor mechanism of C. nitidissima.
