Objective To investigate the pharmacological mechanism of LXHX capsule. Methods The skin specimens from psoriasis patients were examined with TUNEL (terminal deoxynucleotidyl trans-ferase-mediated dUTP-biotin nick end labeling) technique to detect the apoptosis of keratinocytes. PCNA (proliferating cell nuclear antigen) detecting kits was used, too. Then, the flow cytometry, with AnnexinV/PI and PI dyeing method, was used to analysis the effect of LXHX capsule on apoptosis in cultured keratinocytes. Results There was an increasing of both cell apoptosis and proliferation in psoriatic epidermis and LXHX capsule could induce apoptosis. Conclusions The keratinocyte apoptosis and proliferation both increased in psoriasis, which reach a new balance in a higher level. LXHX capsule could induce apoptosis in vitro, which may be one of the pharmacological mechanisms of LXHX in treating psoriasis.

Objective To evaluate the relationship between the amount of grafted cells and the incidence of acute graft versus host disease (aGVHD) after haploid hematopoietic stem cell transplantation (haplo-HSCT). Methods Data of 68 patients who underwent haplo-HSCT from Jan 2009 to Dec 2013 were analyzed retrospectively. Influences of different factors on the incidence of Ⅲ-Ⅳ degree of aGVHD after HSCT were evaluated. Results 68 patients including 42 males and 26 females were 5/10-9/10 HLA match with 19 father donors, 24 mother donors, 16 sibling donors and 9 children donors. 51 patients not suffered Ⅲ-Ⅳdegree of aGVHD included 32 males and 19 females with the mean age of 20 years old (5-55 years old). 17 patients sufferedⅢ-Ⅳdegree of aGVHD including 10 males and 7 females with the mean age of 23 years old (5-54 years old). There were no significant differences in the amount of the grafted mononuclear cells (MNC) and CD34+cells, and the white blood cell counts (WBC) and platelet count (Plt) recovered time between two groups (P>0.05). However, MNC number was related to CD34+cell number (P<0.05) and WBC recover time (P<0.05), and the CD34+cells number was related to WBC and Plt recover time (P< 0.05). Conclusion The incidence of Ⅲ-Ⅳ degree of aGVHD is unrelated to the amount of grafted MNC, and CD34+cells.

Abstract: Objective　To explore the clinical characteristics of nucleic acid negative newborns delivered by pregnant women infected with SARS-CoV-2 (Omicron variant BA. 5.1.3) in Sanya area, and to provide evidence for understanding its clinical characteristics. Methods　A retrospective analysis was performed on 14 neonates with negative nucleic acid delivered by pregnant women who tested positive for SARS-CoV-2 (Omicron variant BA.5.1.3) in Sanya Central Hospital (the Third People's Hospital of Hainan Province) from June 2022 to September 2022 (observation group, n=14). The corresponding nucleic acid-negative newborns delivered by pregnant women detected negative with SARS-CoV-2 (Omicronon variant strain BA.5.1.3) were set as the control group (n=56), and the general data and clinical characteristics of neonates in the two groups were compared. Results　There was no significant difference between the observation group and the control group in pregnancy diabetes, pregnancy induced hypertension, gestational pre-eclampsia, fetal intrauterine distress, premature rupture of membranes (P>0.05); there was no significant difference between the observation group and the control group in terms of sex, gestational age, birth weight, age, mode of delivery, birth Apgar score, heart screening, pulmonary disease, glucose 6-phosphate dehydrogenase (G6PD) deficiency, thalassemia, breast milk jaundice, hemolytic jaundice (P>0.05). The bilirubin level, blue light irradiation cases and the duration of blue light irradiation of the newborns in the observation group at 7 days after birth were higher than those in the control group (P<0.05); the ratio of blood oxygen saturation ≥ 90% in the observation group was lower than that in the control group (21.43% vs 89.29%, P<0.05), and the ratio of blood oxygen saturation occasionally<90% was higher than that in the control group (57.14% vs 10.71%, P<0.05). The ratio of blood oxygen saturation<90% had no significant difference compared with that in the control group (7.14% vs 0, P>0.05), and the ratio of blood oxygen saturation reduced to the required oxygen uptake was higher than that in the control group (14.29% vs 0, P<0.05). Conclusions　The jaundice manifestation of the nucleic acid-negative newborns delivered by pregnant women infected with SARS-CoV-2 (Omicronon variant strain BA.5.1.3) in Sanya area is relatively obvious, with blood oxygen saturation easily lower than 90% and even requiring oxygen inhalation in severe cases.

BACKGROUND:Oligodendrocytes are mostly differentiated from oligodendrocyte precursor cel s. A suitable medium and cel seeding density have a significant impact on the process of the isolation of oligodendrocyte precursor cel s to obtain oligodendrocytes. OBJECTIVE:To explore the optimization of oligodendrocyte culture conditions. METHODS:Oligodendrocyte precursor cel s isolated from the newborn rats 48 hours after birth were cultured in DMEM/high glucose medium or DMEM/F12 medium using seeding densities of 2×104 cel s/cm2, 4×104 cel s/cm2, 8×104 cel s/cm2, 16×104 cel s/cm2, 32×104 cel s/cm2, and 64×104 cel s/cm2, respectively. Oligodendrocyte precursor cel s were induced to differentiate into oligodendrocytes at 72 hours after cel adhesion. Morphology of differentiated oligodendrocyte precursor cel s were observed under a light microscope, and the differentiation results were identified by immunofluorescence staining after 7-day induced differentiation. RESULTS AND CONCLUSION:Morphology of oligodendrocyte precursor cel s were recognized when cultured in DMEM/high glucose medium or DMEM/F12 medium using seeding densities of 2×104 cel s/cm2, 4×104 cel s/cm2, and 8×104 cel s/cm2, respectively. Immunofluorescence staining showed that myelin basic protein-positive cel s were found after 7-day induced differentiation, and the positive cel number were 16.40±3.30, 49.95±2.33, and 76.95±4.86 in DMEM/F12 medium, and 12.65±2.53, 32.10±1.17, and 54.05±1.56 in DMEM/high glucose medium (P<0.05). These findings indicate that DMEM/F12 medium is more suitable for culturing oligodendrocyte precursor cel s compared with DMEM/high glucose medium to some extent. The number of differentiated oligodendrocytes was gradual y increased with the enhanced seeding density of oligodendrocyte precursor cel s, and the seeding densities from 4×104 to 8×104 cel s/cm2 were appropriate for the observation of cel morphology.

Objective To evaluate the efficacy and safety of acute ureteroscopy for the treatment of ureterie stones during middle and late pregnancy.Methods From June 1998 to March 2005,17 pregnant women(mean age,27 years;age range,21-35 years)with ureteric stones were treated by ureteroscopy when the fetus was at 20-36 weeks of gestation(mean,29 weeks).All the cases presented with urgent symptoms such as recurrent renal colic(11 cases),fever(4)or acute obstructive anuria(2).Among 17 cases,the stones(between 6 mm?7 mm and 13 mm?21 mm)were located in the upper(8 cases),middle(5)or lower ureter(4);and on the left side(5 eases),on the right(10)and on both(2)of the lower ureter. Mild hydronephrosis were observed in 6 cases and moderate hydronephrosis in 11,Of the 17 cases,14 under- went ureteroscopic pneumatic lithotripsy;in 1 case the calculi were pushed to the renal pelvis;and 2 cases were treated by Double-J catheter drainage.Results All the urgent symptoms in 17 cases were relieved after treatment.The stone-free rate of initial treatment was 82.4%(14 of 17).Three cases with residual stones were treated by Douhle-J catheters,which were replaced every 3 months until the calculi were re- moved.No abortion,premature delivery or complications such as ureter perforation occurred.Mild renal colic occurred in 1 case after insertion of Douhle-J catheter,and it was relieved 3d later;gross hematuria occurred in l case and disappeared 6 d later without treatment.All 17 patients had normal delivery and gave birth to healthy children.Conclusions Ureteroscopy is a safe and reliable method for the treatment of ureteric calculi during middle and late pregnancy.

Objective To improve the diagnosis efficiency of patients with angioimmunoblastic T-cell lymphoma (AILT)by analyzing the clinical characteristics and curative effect of AILT. Methods Retrospective studies were used on clinicopathological features,immunophenotypes,treatment and survival of 20 angioimmunoblastic T-cell lymphoma patients,who were collected between January 2005 and January 2010 of Beijing Military General Hospital. Results In the 20 patients receiving chemotherapy,the median age was 55.9 years old.All of the 20 had lymph nodes and 11 of whom were accompanied with B group of symptoms,which were confirmed by lymph node biopsy and T cell antigen CD3, CD45Ro positive expression in all the patients. ALL of the patients received the CHOP regimen and combining with other treatment such as DICE,ESHAP, Hyper-CVAD or autologous hematopoietic stem cell transplantation. A follow-up by 5 to 69 months showed that median survival was 20.2 (5-69) months and 1,2,and 3-year disease free survival (DFS) were 67 ％,33 ％,and 11％ respectively.8 patients of the group (40 ％) with a sustained remission (CCS) respectively survived 63,47,27,24,24,12,5,1 months so far.Conclusion Most patients were older with many complications during chemotherapy, which resulted in easy relapse, and even the symptoms were alleviated at the early stage of the chemotherapy. IPI prognostic index is more important with long-term survival in AITL.Therefore further studies are required to improve the outcome.

OBJECTIVETo explore the associations between fasting serum lipids and high-sensitivity C-reactive protein (hsCRP).

METHODSSerum triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and hsCRP were measured in residents of Chengdu, China. Subjects with potential factors which might influence lipids and hsCRP were excluded, 580 subjects [mean age (62.3 ± 6.6) years; male: 58.7%] were finally recruited by random sampling methods.

RESULTSThere was a weak positive relationship between TG and hsCRP (r = 0.108, P = 0.01) and a weak negative relationship between HDL-C and hsCRP (r = -0.197, P < 0.001), this was also true in the sub-group with BMI < 24 kg/m(2) (r = 0.236, -0.140 respectively, all P < 0.001). In subjects with BMI < 24 kg/m(2), the hsCRP concentration was significantly higher in subjects with higher TG or lower HDL-C (all P < 0.05). hsCRP increased in proportion with the degree of dyslipidemia. After adjusting for gender, age, TC, LDL-C, fasting blood glucose, systolic blood pressure, diastolic blood pressure, history of hypertension and diabetes, smoking and alcohol drinking, logistic regression analysis showed that the odds ratio for increased hsCRP was 1.970 in subjects with either increased TG or lower HDL-C (P = 0.105) and 9.098 in subjects with both higher TG or lower HDL-C levels (P = 0.031). However, the observed relationship between TG, HDL-C and hsCRP in subjects with BMI < 24 kg/m(2) could not be observed in subjects with subjects with BMI > 24 kg/m(2) despite significant more cardiovascular risk factors in these subjects.

CONCLUSIONSA weak positive correlation between TG and hsCRP as well as a weak negative correlation between HDL-C and hsCRP was evidenced in the whole cohort suggesting dyslipidemia might be related to enhanced inflammatory status. However, this relationship is not observed in subjects with BMI > 24 kg/m(2) despite existence of more cardiovascular risk factors in these subjects.
