ObjectiveTo explore the characteristics of circadian rhythm of blood pressure in patients with masked hypertension (MH) and its relationship with twelve two-hour peirods, providing a basis for early detection and intervention of MH. MethodsPatients who underwent 24-hour ambulatory blood pressure examination in the ambulatory blood pressure room of Jiangsu Province Hospital of Chinese Medicine from January to December 2022 were enrolled, and according to their outpatient blood pressure measurements, 24-hour ambulatory blood pressure monitoring and follow-up survey results, the MH, essential hypertension (EH) and normal blood pressure groups were classified, with 50 cases in each group. The general data, office blood pressure and 24-hour ambulatory blood pressure monitoring data were collected. The circadian rhythm of blood pressure including 24-hour average systolic blood pressure (24h SBP), daytime average systolic blood pressure (d SBP), nighttime average systolic blood pressure (n SBP), 24-hour average diastolic blood pressure (24h DBP), daytime average diastolic blood pressure (d DBP), and nighttime average diastolic blood pressure (n DBP) were compared among the groups, and the nighttime blood pressure dipping percentage was calculated. The type of circadian rhythm was determined based on the nighttime blood pressure dipping percentage. The variability of blood pressure including 24h SBP standard deviation (24h SBP-SD), d SBP standard deviation (dSBP-SD), n SBP standard deviation (nSBP-SD), 24h DBP standard deviation (24h DBP-SD), d DBP standard deviation (dDBP-SD), and n DBP standard deviation (nDBP-SD) were compared among groups, and the corresponding coefficient of variation (CV), that is, 24h SBP-CV, d SBP-CV, n SBP-CV, 24h DBP-CV, d DBP-CV and n DBP-CV, were calculated. Based on the 24-hour ambulatory blood pressure monitoring results, the twelve two-hour average SBP and DBP in each group were calculated and compared. Simultaneously, patients with EH were divided into grades 1, 2, and 3 for further stratified analysis. ResultsThe age of the MH group was significantly higher than that of the EH group and the normal blood pressure group (P<0.01). The body mass index (BMI) and the proportion of smoking and alcohol consumption in the MH group and the EH group were significantly higher than those in the normal blood pressure group (P<0.05 or P<0.01). In the normal blood pressure group, there were 49 dipper patterns (98.0%) and one non-dipper pattern (2.0%); in the MH group, there were two dipper patterns (4.0%), 29 non-dipper patterns (58.0%) and 19 reverse-dipper patterns (38.0%); in the EH group, there were 20 dipper patterns (40.0%), 23 non-dipper patterns (46.0%) and seven reverse-dipper patterns (14.0%). Compared to the normal blood pressure group, the groups of MH and EH had significantly decreased proportion of dipper pattern and increased proportion of non-dipper and reverse-dipper pattern (P<0.01); the proportion of dipper pattern in the MH group was lower than that in the EH group, while the proportion of reverse-dipper pattern was higher (P<0.01). Compared to those in the normal blood pressure group, n SBP and n DBP in the MH group, as well as the the average SBP and average DBP at Zi hour (子时, 23:00-1:00), Chou hour (丑时, 1:00-3:00), Yin hour (寅时, 3:00-5:00), Mao hour (卯时, 5:00-7:00) and average SBP at Hai hour (亥时, 21:00-23:00) in the MH group increased,while the average DBP at Si hour (巳时, 9:00-11:00) decreased (P<0.01); 24h SBP, 24h DBP, d SBP, d DBP, n SBP, and n DBP,d SBP-SD, n SBP-SD,n DBP-SD increased, as well as the average SBP and average DBP at twelve two-hour periods increased in the EH group,while the 24h SBP-CV, 24h DBP-CV,and d DBP-CV in the EH group decreased(P<0.05 or P<0.01). The EH group had higher 24h SBP, 24h DBP, d SBP, d DBP, n SBP, n DBP, 24h DBP-SD and n DBP-SD , as well as higher average SBP and DBP at all twelve two-hour periods, and lower d DBP-CV than the MH group(P<0.05 or P<0.01). The EH group had 18 cases of grade 1 (36.0%), 19 cases of grade 2 (38.0%) and 13 cases of grade 3 (26.0%), with no significant differences among groups (P>0.05). ConclusionThe circadian rhythm of blood pressure in MH patients are mostly non-dipper and reverse-dipper patterns, and the abnormal elevation of blood pressure is obvious at Zi hour, Chou hour, Yin hour and Mao hour (23:00-7:00).

Glaucoma is a chronic optic neuropathy that affects the retinal ganglion cells, characterized by optic disc atrophy, visual field defects, and visual acuity loss. Since glaucoma is a chronic disease, long-term use of topical intraocular pressure-lowering medications often leads to ocular surface diseases, thus reducing medication adherence and ultimately affecting treatment efficacy. Currently, topical intraocular pressure-lowering medications include prostaglandin derivatives, β-adrenergic blockers, α-adrenergic agonists, topical carbonic anhydrase inhibitors, and cholinergic drugs. This article provides a comprehensive review of the effects and related mechanisms of these five antiglaucoma medications on the ocular surface of glaucoma patients and offers preventative measures for the protection of ocular surface in glaucoma patients.

Emerging SARS-CoV-2 variants have made COVID-19 convalescents susceptible to re-infection and have raised concern about the efficacy of inactivated vaccination in neutralization against emerging variants and antigen-specific B cell response. To this end, a study on a long-term cohort of 208 participants who have recovered from COVID-19 was conducted, and the participants were followed up at 3.3 (Visit 1), 9.2 (Visit 2), and 18.5 (Visit 3) months after SARS-CoV-2 infection. They were classified into three groups (no-vaccination (n = 54), one-dose (n = 62), and two-dose (n = 92) groups) on the basis of the administration of inactivated vaccination. The neutralizing antibody (NAb) titers against the wild-type virus continued to decrease in the no-vaccination group, but they rose significantly in the one-dose and two-dose groups, with the highest NAb titers being observed in the two-dose group at Visit 3. The NAb titers against the Delta variant for the no-vaccination, one-dose, and two-dose groups decreased by 3.3, 1.9, and 2.3 folds relative to the wild-type virus, respectively, and those against the Omicron variant decreased by 7.0, 4.0, and 3.8 folds, respectively. Similarly, the responses of SARS-CoV-2 RBD-specific B cells and memory B cells were boosted by the second vaccine dose. Results showed that the convalescents benefited from the administration of the inactivated vaccine (one or two doses), which enhanced neutralization against highly mutated SARS-CoV-2 variants and memory B cell responses. Two doses of inactivated vaccine among COVID-19 convalescents are therefore recommended for the prevention of the COVID-19 pandemic, and vaccination guidelines and policies need to be updated.

Objective: To evaluate the advantages and safety of Plerixafor in combination with granulocyte colony-stimulating factor (G-CSF) in autologous hematopoietic stem cell mobilization of lymphoma. Methods: Lymphoma patients who received autologous hematopoietic stem cell mobilization with Plerixafor in combination with G-CSF or G-CSF alone were obtained. The clinical data, the success rate of stem cell collection, hematopoietic reconstitution, and treatment-related adverse reactions between the two groups were evaluated retrospectively. Results: A total of 184 lymphoma patients were included in this analysis, including 115 cases of diffuse large B-cell lymphoma (62.5%) , 16 cases of classical Hodgkin's lymphoma (8.7%) , 11 cases of follicular non-Hodgkin's lymphoma (6.0%) , 10 cases of angioimmunoblastic T-cell lymphoma (5.4%) , 6 cases of mantle cell lymphoma (3.3%) , and 6 cases of anaplastic large cell lymphoma (3.3%) , 6 cases of NK/T-cell lymphoma (3.3%) , 4 cases of Burkitt's lymphoma (2.2%) , 8 cases of other types of B-cell lymphoma (4.3%) , and 2 cases of other types of T-cell lymphoma (1.1%) ; 31 patients had received radiotherapy (16.8%) . The patients in the two groups were recruited with Plerixafor in combination with G-CSF or G-CSF alone. The baseline clinical characteristics of the two groups were basically similar. The patients in the Plerixafor in combination with the G-CSF mobilization group were older, and the number of recurrences and third-line chemotherapy was higher. 100 patients were mobilized with G-CSF alone. The success rate of the collection was 74.0% for one day and 89.0% for two days. 84 patients in the group of Plerixafor combined with G-CSF were recruited successfully with 85.7% for one day and 97.6% for two days. The success rate of mobilization in the group of Plerixafor combined with G-CSF was substantially higher than that in the group of G-CSF alone (P=0.023) . The median number of CD34(+) cells obtained in the mobilization group of Plerixafor combined with G-CSF was 3.9×10(6)/kg. The median number of CD34(+) cells obtained in the G-CSF Mobilization group alone was 3.2×10(6)/kg. The number of CD34(+) cells collected by Plerixafor combined with G-CSF was considerably higher than that in G-CSF alone (P=0.001) . The prevalent adverse reactions in the group of Plerixafor combined with G-CSF were grade 1-2 gastrointestinal reactions (31.2%) and local skin redness (2.4%) . Conclusion: The success rate of autologous hematopoietic stem cell mobilization in lymphoma patients treated with Plerixafor combined with G-CSF is significantly high. The success rate of collection and the absolute count of CD34(+) stem cells were substantially higher than those in the group treated with G-CSF alone. Even in older patients, second-line collection, recurrence, or multiple chemotherapies, the combined mobilization method also has a high success rate of mobilization.

Objective: To evaluate the clinical effects of low- and intermediate-dose factor Ⅷ (F Ⅷ) prophylaxis in Chinese adult patients with severe hemophilia A. Methods: Thirty adult patients with severe hemophilia A who received low- (n=20) /intermediate-dose (n=10) F Ⅷ prophylaxis at Nanjing Drum Tower Hospital affiliated with Nanjing University Medical College were included in the study. The annual bleeding rate (ABR), annual joint bleeding rate (AJBR), number of target joints, functional independence score of hemophilia (FISH), quality of life score, and health status score (SF-36) before and after preventive treatment were retrospectively analyzed and compared. Results: The median follow-up was 48 months. Compared with on-demand treatment, low- and intermediate-dose prophylaxis significantly reduced ABR, AJBR, and the number of target joints (P<0.05) ; the improvement in the intermediate-dose prophylaxis group was better than that in the low-dose prophylaxis group (P<0.05). Compared with on-demand treatment, the FISH score, quality of life score, and SF-36 score significantly improved in both groups (P<0.05), but there was no significant difference between the two groups (P>0.05) . Conclusion: In Chinese adults with severe hemophilia A, low- and intermediate-dose prophylaxis can significantly reduce bleeding frequency, delay the progression of joint lesions, and improve the quality of life of patients as compared with on-demand treatment. The improvement in clinical bleeding was better with intermediate-dose prophylaxis than low-dose prophylaxis.

Both anti-glomerular basement membrane (GBM) disease and the anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) are common causes of pulmonary-renal syndrome. Organizing pneumonia (OP), a special pattern of interstitial lung disease, is extremely rare either in AAV or anti-GBM disease. We report an old woman presented with OP on a background of co-presentation with both ANCA and anti-GBM antibodies.

OBJECTIVE:
To analyze the characteristics and prognosis of acute leukemia(AL) with SET-NUP214 fusion gene.
METHODS:
The clinical data of 17 patients over 14 years old newly diagnosed with SET-NUP214 positive AL admitted in Institute of Hematology and Blood Diseases Hospital from August 2017 to May 2021 were analyzed retrospectively.
RESULTS:
Among the 17 SET-NUP214 positive patients, 13 cases were diagnosed as T-ALL (ETP 3 cases, Pro-T-ALL 6 cases, Pre-T-ALL 3 cases, Medullary-T-ALL 1 case), AML 3 cases (2 cases M5, 1 case M0) and ALAL 1 case. Thirteen patients presented extramedullary infiltration at initial diagnosis. All 17 patients received treatment, and a total of 16 cases achieved complete remission (CR), including 12 cases in patients with T-ALL. The total median OS and RFS time were 23 (3-50) months and 21 (0-48) months, respectively. Eleven patients received allogeneic hematopoietic stem cell transplantation(allo-HSCT), with median OS time of 37.5 (5-50) months and median RFS time of 29.5 (5-48) months. The median OS time of 6 patients in chemotherapy-only group was 10.5 (3-41) months, and median RFS time of 6.5 (3-39) months. The OS and RFS of patients with transplantation group were better than those of chemotherapy-only group (P=0.038). Among the 4 patients who relapsed or refractory after allo-HSCT, the SET-NUP214 fusion gene did not turn negative before transplantation. While, in the group of 7 patients who have not relapsed after allo-HSCT till now, the SET-NUP214 fusion gene expression of 5 patients turned negative before transplantation and other 2 of them were still positive.
CONCLUSION
The fusion site of SET-NUP214 fusion gene is relatively fixed in AL patients, often accompanied by extramedullary infiltration. The chemotherapy effect of this disease is poor, and allo-HSCT may improve its prognosis.

AIM: To investigate the effectiveness of panretinal photocoagulation(PRP)combined with intravitreal conbercept(IVC)for patients with different stages of proliferative diabetic retinopathy(PDR).METHODS: Retrospective study. The medical records for 100 patients(100 eyes)with PDR treated with PRP combined with IVC from January 2018 to June 2020 were reviewed, including 34 eyes with early PDR(group A), 43 with high-risk PDR(group B), and 23 with fibrovascular PDR(group C). The baseline information, best corrected visual acuity(BCVA), central macular thickness(CMT), the rate of vitrectomy and retinal detachment of the patients in the three groups at 1, 3, 6mo and the last follow-up after combination treatment were observed.RESULTS: The patients were followed up for 14.60±11.64mo(6-52mo), with a mean age of 54.22 ±9.32 years. We found 15 eyes(15.0%)who underwent vitrectomy after the combination treatment. The vitrectomy rates of the three groups were 2.9% in group A, 13.9% in group B, and 34.7% in group C. We found no instances of retinal detachment after the treatments. Most patients demonstrated improved BCVA and CMT values with the treatments.CONCLUSION: PRP combined with IVC is safe and effective in patients with different PDR stages.

OBJECTIVE:
To detect the body surface temperature of the relevant back-shu points in patients with chronic persistent asthma by infrared thermal imaging technology, and observe the specific changes of the body surface temperature of the relevant back-shu points under the condition of lung disease.
METHODS:
Forty-five patients with chronic persistent asthma (observation group) and 45 healthy subjects (control group) were selected. The body surface temperature of bilateral Feishu (BL 13), Geshu (BL 17), Pishu (BL 20) and Shenshu (BL 23) were measured by BK-MT02A medical infrared thermography.
RESULTS:
The body surface temperature of bilateral Feishu (BL 13), Geshu (BL 17), Pishu (BL 20) and Shenshu (BL 23) in the observation group was higher than that in the control group (P<0.01, P<0.05). The body surface temperature of bilateral Feishu (BL 13) and Geshu (BL 17) was higher than that of ipsilateral Pishu (BL 20) and Shenshu (BL 23) in the two groups (P<0.01, P<0.05). There was no statistically significant difference in body surface temperature between ipsilateral Feishu (BL 13) and Geshu (BL 17), between ipsilateral Pishu (BL 20) and Shenshu (BL 23) (P>0.05).
CONCLUSION
The pathological increase of body surface temperature of Feishu (BL 13), Geshu (BL 17), Pishu (BL 20) and Shenshu (BL 23) in patients with chronic persistent asthma indicates that above acupoints have specificity in reflecting lung diseases. The Feishu (BL 13) and Geshu (BL 17), which have significantly increased body surface temperature, not only provide objective basis for the pathological pathogenesis of "deficiency in origin and excess in symptom" in patients with chronic persistent asthma, but also reflect the different expressions of different acupoints on the same meridian for the lung diseases.
