The Connotation and Clinical Significance of “Spleen Governs Time” based on the Zangxiang （藏象） Time-space View / 中医杂志

There are different views on the theory of “spleen governs time”， which is still a hot spot in the study of Zangxiang （藏象） theory. Based on Zangxiang time-space view， it is found that the thinking mode of the spleen governing time theory follows space-time logic. It is believed that the different time views of the spleen governing time are all formed based on the space view that the spleen belongs to earth and resides in the center， and the zang time theory is developed with the unified time and space logic. Guided by Zangxiang time-space view， the origin of the spleen belonging to earth and residing in the center is traced， and the theoretical connotation and its clinical application of spleen governing time under different time-space logic are explored with reference to the four season and five zang theory， five season and five zang theory， six season and six zang theory， and eight season and eight zang theory.

Classification and reduction techniques of irreducible intertrochanteric fractures based on reduction stage and bone block position / 中华创伤骨科杂志

Objective:To explore our self-designed classification system of irreducible intertrochanteric fractures based on reduction stage and bone block position and to evaluate the reduction techniques guided by the classification system.Methods:A retrospective study was conducted to analyze the data of 115 patients with irreducible intertrochanteric fracture who had been admitted to Department of Orthopedics, Beijing Hospital from September 2014 to November 2022. There were 24 males and 91 females with a mean age of (80.9±11.0) years. The reduction for the fractures was divided into a diaphysis reduction stage (Phase Ⅰ) and a cortical reduction stage (Phase Ⅱ). Based on the relative positions of the intraoperative bone blocks, Phase Ⅰ was divided into an anterior and posterior interlocking type (Phase Ⅰa) and a distal bone block sinking displacement type (Phase Ⅰb) while Phase Ⅱ into a proximal lifting type (Phase Ⅱa), a posterior angulation type (Phase Ⅱb), a positive support type (Phase Ⅱc), and a negative support type (Phase Ⅱd). Depending on the difficulties encountered in different reduction stages, corresponding close reduction strategies (such as top rod support, percutaneous prying, and Joystick technique) were adopted to restore the proximal femoral neck shaft angle, anteversion angle, anterior medial cortex, and length of the affected limb before fixation with intramedullary nails. Recorded were the patient's surgical time, intraoperative bleeding, quality of postoperative reduction, fracture union time, and complications.Results:The surgical time for this group of patients was 70.0(60.0, 92.0) minutes, and the intraoperative blood loss 200.0 (170.0, 200.0) mL. According to the standards by Baumgaertner et al., the quality of postoperative reduction was evaluated as excellent in 103 cases and as good in 12 cases, with an excellent and good rate of 100.0% (115/115). Of the 115 patients, 86 were followed up for more than 6 months to reveal fracture union in all after a duration of 6.0 (4.0, 8.0) months. One patient died of an acute cardiovascular event in the hospital 5 days after surgery. Two patients lost their mobility within 3 months after surgery due to acute cerebral infarction. There was no internal fixation failure requiring secondary surgery or no incision infection.Conclusion:Guided by our self-designed classification system of irreducible intertrochanteric fractures based on the intraoperative reduction stage and the relative position of bone block, real time intraoperative fluoroscopy images can be used to effectively clarify the difficulty of fracture reduction in stages so that corresponding reduction strategies can be adopted, leading to fine clinical efficacy.

Epidemiological characteristics analysis of hip fractures in the elderly / 中华老年医学杂志

Objective:To analyze the epidemiological characteristics of geriatric hip fractures.Methods:This study retrospectively analyzed the clinical characteristics of 2 054 elderly patients with hip fracture aged 60 years and over who were admitted to Beijing Hospital from January 2011 to December 2020.The epidemiological characteristics of geriatric hip fractures were analyzed from the aspects of age, gender, fracture type, length of stay, surgical method and surgical complications.Results:The total number of hip fractures patients admitted from 2011 to 2020 showed a general upward trend in quantity.Among them, there were 1 177 femoral neck fractures(57.3%, 1 177/2 054), and 877 intertrochanteric femoral fractures(42.7%, 877/2 054)with statistical differences in the distribution of fracture types between patients at different ages( χ2=61.727, P<0.001). A total of 1 839 patients chose surgical treatment, accounting for 89.5% of the total number of patients.Artificial femoral head arthroplasty was the most common operation mode for patients with femoral neck fractures(783 cases, 75.4%).534 patients with intertrochanteric femoral fractures(66.8%)were treated with closed reduction and femoral intramedullary nailing.There was a statistically significant difference in operation modes among different fracture types( χ2=1 480.800, P<0.001). The length of hospital stay in patients with femoral neck fracture was(14.2±8.3)days, which was significantly longer than in patients with femoral neck fracture(13.2±10.9)days( t=2.417, P=0.016). There was no significant difference in the time from admission to operation between the two groups[(5.7±3.5)days vs.(5.4±3.3)days]( t=1.954, P=0.051). Among all the comorbidities of hip fracture patients, the top 5 diseases were cardiovascular system diseases(2 001 cases, 97.4%), nervous system diseases(1 105 cases, 53.8%), endocrine system diseases(814 cases, 39.6%), skeletal and muscular system diseases(623 cases, 30.3%), digestive system diseases(472 cases, 23.0%).1 485 patients(72.3%)had 3 or more comorbidities. Conclusions:Hip fractures in the elderly have some epidemiological distribution characteristics in terms of age, gender, length of hospitalization, injury mechanism and comorbidities, which is conducive to further improve the prevention and treatment strategies for hip fractures and promote the rational allocation of medical resources.

The flow density of macular and optic disc and area of foveal avascular zone in severe nonproliferative diabetic retinopathy / 中华眼底病杂志

Objective:To observe the flow density (FD) of macular and optic disc and area of foveal avascular zone (FAZ) in severe nonproliferative diabetic retinopathy (S-NPDR).Methods:A prospective cross-sectional study. From October 2019 to April 2020, 31 eyes of 25 S-NPDR patients (S-NPDR group) who were diagnosed in the ophthalmological examination of Jiangsu Province Hospital and 30 eyes of 30 age- and sex-matched healthy volunteers (control group) were included in this study. Optical coherence tomography angiography (OCTA) was used to scan the macular area of 6 mm×6 mm and optic disc of 4.5 mm×4.5 mm. The software automatically divides it into three concentric circles centered on the macular fovea, which were foveal area with a diameter of 1 mm, parafoveal area of 1 to 3 mm, and foveal peripheral area of 3 to 6 mm. The area around the optic disc was divided into 8 areas: nasal upper, nasal lower, inferior nasal, inferior temporal, temporal lower, temporal upper, superior temporal and superior nasal. The FD of the optic disc, the superficial capillary layer (SCP) and deep capillary layer (DCP) of the retina and FAZ area were measured. The FD and FAZ area were compared between the two groups by independent sample t test. The correlation between FAZ area and FD was analyzed by Pearson correlation. Results:In parafoveal and perifoveal area, compared with the control group, the FD of SCP ( t=6.470, 5.220; P<0.001) and DCP ( t=7.270, 7.370; P<0.001) decreased in S-NPDR group. In foveal area, there was statistically significant difference in the FD of DCP between the two groups ( t=2.250, P=0.030), while the difference in FD of SCP between the two groups was not statistically significant ( t=0.000, P=0.900). The FAZ area in S-NPDR group was larger than that in control group, and the difference was statistically significant ( t=2.390, P=0.030). The FD in the S-NPDR group was lower than that in the control group except the superior nasal, the difference was statistically significant ( t=7.520, 5.000, 4.870, 3.120, 2.360, 2.120, 5.410, 5.560, 2.640; P<0.05). Pearson correlation analysis showed that the FAZ area of S-NPDR was negatively correlated with FD of SCP ( r=-0.513, P=0.004), and had no correlation with FD of DCP ( r=0.034, P=0.859). Conclusion:The overall FD in macular area and optic disc of patients with S-NPDR decreased and the FAZ area enlarged.

Effects of FGF-2 on the intercellular communication in the cardiac myocytes / 解放军医学杂志

Objective To investigate the effects of FGF 2 on the intercellular communication in the cardiac myocytes. Methods The primary neonatal ventricular myocytes of rats were cultured with FGF 2 (0,1,10,100 and 1000ng/ml) for 1 or 4 days. Then the mean fluorescence recovery rate (MFRR, %/min) of these myocytes labeled with carboxyfluocein diacetate after photo bleaching was examined with laser scanning cytopmetry (ACAS Ultima). Results The MFRR levels of the myocytes cultured with FGF 2 (10 and 100ng/ml) groups for 1 day were significantly decreased compared with the control group, while no statistic changes were found among the other groups (FGF 2, 1 and 1000ng/ml) and the control. After FGF 2 exertion on the myocytes for 4 days, the increased cell number, enlarged cellular body and decreased MFRR level were found in the myocytes cultured with FGF 2 (10 and 100ng/ml) groups. And the decreased cell number, disarranged and shrunk cells and significantly increased MFRR level were gotten in the group (FGF 2 1000ng/ml) compared with the control group. Conclusion These results suggested the FGF 2 may have both short and long term effects on the cell cell communication in the cardiac myocytes mediated by gap junction, and be necessary to the cardiac myocyte coordination during the cell growth, differentiation and perhaps apoptosis.
