BACKGROUNDRegulatory T-cells (Treg) play key roles in suppressing cell-mediated immunity in cancer patients. Little is known about perioperative Treg fluctuations in nonsmall cell lung cancer (NSCLC). Video-assisted thoracoscopic (VATS) lobectomy, as a minimal invasive procedure for treating NSCLC, may have relatively less impact on the patient's immune system. This study aimed to observe perioperative dynamics of circulating Treg and natural killer (NK) cell levels in NSCLC patients who underwent major lobectomy by VATS or thoracotomy.
METHODSTotally, 98 consecutive patients with stage I NSCLC were recruited and assigned into VATS or thoracotomy groups. Peripheral blood samples were taken on 1-day prior to operation, postoperative days (PODs) 1, 3, 7, 30, and 90. Circulating Treg and NK cell counts were assayed by flow cytometry, defined as CD4 + CD25 + CD127 low cells in CD4 + lymphocytes and CD56 + 16 + CD3- cells within CD45 + leukocytes respectively. With SPSS software version 21.0 (SPSS Inc., USA), differences between VATS and thoracotomy groups were determined by one-way analysis of variance (ANOVA), and differences between preoperative baseline and PODs in each group were evaluated by one-way ANOVA Dunnett t-test.
RESULTSIn both groups, postoperative Treg percentages were lower than preoperative status. No statistical difference was found between VATS and thoracotomy groups on PODs 1, 3, 7, and 30. On POD 90, Treg percentage in VATS group was significantly lower than in thoracotomy group (5.26 ± 2.75 vs. 6.99 ± 3.60, P = 0.012). However, a higher level of NK was found on all PODs except on POD 90 in VATS group, comparing to thoracotomy group.
CONCLUSIONSLower Treg level on POD 90 and higher NK levels on PODs 1, 3, 7, 30 in VATS group might imply better preserved cell-mediated immune function in NSCLC patients, than those in thoracotomy group.

OBJECTIVE:
To delineate the nature and origin of a chromosomal aberration detected in a boy with mental retardation.
METHODS:
The proband and his parents were subjected to routine G-banded chromosomal karyotyping and single nucleotide polymorphism array (SNP-array) analysis.
RESULTS:
The karyotype of the proband was determined as 46, XX, add(8)(p23). No karyotypic abnormality was detected in either of his parents. SNP-array has identified a 34.9 Mb duplication at 8p23.1q11.1 and a 6.78 Mb microdeletion at 8p23.1pter in the proband. No copy number variation was detected in either parent.
CONCLUSION
The child was diagnosed with 8p inverted duplication deletion syndrome, which might be induced by non-allelic homologous recombination between olfactory genes in the 8p23.1 region.

In recent years, the clinical experts consensuses or guidelines of ankylosing spondylitis (AS)/spondyloarthritis (SpA) have been constantly updated, but to better understand and practice, patient self-participation management is one of the key points to improve the level of diagnosis and treatment. Through questionnaire survey of these patients, we screened out the most concerned issues, and established the AS/SpA patient practice guideline working group with multidisciplinary physicians and patients. Fifteen opinions, as the AS/SpA patient practice guidelines, are proposed in accordance with the relevant principles of the "WHO guidelines development manual" , and with the international normative process.

To investigate the expression of small dense low-density lipoprotein cholesterol (sdLDL-C) in patients with H-type hypertension and its association with H-type hypertension and methylenetetrahydrofolate reductase (MTHFR) gene polymorphisms. The retrospective study method was used,and a total of 207 hospitalized hypertensive patients (76 males and 131 females, aged 40-82 years, median age 66 years) admitted to the Zibo First Hospital from March 2021 to March 2022 were enrolled in this study. The levels of homocysteine (Hcy), sdLDL-C, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), total cholesterol (TC), triglyceride (TG) and lipoprotein (a) [Lp(a)] were measured. The patients were divided into H-type hypertensive group (n=105, 40 males and 65 females) and non-H-type hypertensive group (n=102, 36 males and 66 females) according to Hcy levels. The C677T polymorphism of methylenetetrahydrofolate reductase (MTHFR) gene was detected in each group. Logistic regression analysis was performed for the related factors of H-type hypertension. The serum sdLDL-C levels were (0.92±0.31) and (0.65±0.28) mmol/L in H-type hypertension group and non-H-type hypertension group, respectively. The sdLDL-C levels in H-type hypertension group were significantly higher than those in non-H-type hypertension group (t=6.500, P<0.01). There was no significant difference in the serum sdLDL-C levels between males and females in H-type hypertension group (t=-1.543, P=0.129). The CC, CT, TT genotypes and C and T allele frequencies of MTHFR C677T in H-type hypertension group were significantly different from those in non-H-type hypertension group (P<0.05). The Hcy and sdLDL-C levels in different genotypes of MTHFR in H-type hypertension group were significantly different (H=12.742, P=0.002; F=3.345, P=0.042). Among them, Hcy levels were higher in TT genotype than in CT and CC genotypes, respectively (Z=-28.099, P=0.003; Z=-16.112, P=0.040), and sdLDL-C levels were higher in TT genotype than in CC genotype (t=-2.587, P=0.012). Logistic regression analysis showed that age, sdLDL-C, and MTHFRC677T TT genotypes were associated with the development for H-type hypertension. In conclusion, the level of sdLDL-C is associated with MTHFR gene polymorphisms and may be associated with the development of H-type hypertension.

Chinese herbal medicine ultrafine powder has become a research hotspot for the addition of cosmetic raw materials. Dendrobium candidum is a traditional Chinese herbal medicine. Its extract and stem extract are already cosmetic raw materials and its water extract has the effect of preventing photoaging,but D. candidum ultrafine powder has not been accepted as a raw material for cosmetics,and no relevant research on photoaging prevention has been reported. In this experiment,the ultra-fine powder and fine powder of D. candidum to prevent photoaging were observed and compared,and its mechanism of action was discussed to provide a basis for the prevention of skin photoaging products. Seventy-two female ICR mice were randomly divided into normal group,model group,solvent group,titanium dioxide(Ti O2) group,isooctyl salicylate(2-ES) group,D. candidum ultrafine powder 1(DP1),ultrafine powder 2(DP2) and fine powder(DP3) groups. The photoaging model was established by ultraviolet irradiation for 8 weeks,and the model was intervened while modeling. The skin wrinkle grade,elastic parameters,skin microcirculation blood flow,skin structure and pathological changes(skin thickness,skin collagen fiber,elastic fiber) were observed,the skin transforming growth factor-β1(TGF-β1),Smad3 levels were determined,and the type Ⅰ and type Ⅲ collagen,matrix metalloproteinase-1(MMP-1),activated protein-1(AP-1),VEGF expression were detected. The results showed that ultrafine powder(DP1,DP2) significantly reduced the wrinkle level and skin blood flow of the model mice(P<0. 05,P<0. 01); DP1,DP2 and DP3 could significantly reduce the thickness of the epidermis(P<0. 001),improve collagen fiber,elastic fiber hyperplasia,and distortion and decrease VEGF expression,and DP1 is better than DP2 and DP3; each group could up-regulate type Ⅰ collagen,down-regulate type Ⅲ collagen,AP-1,MMP-1 protein expression,and DP1 improvement optimal. However,it has no obvious effect on TGF-β1 and Smad3. The ultrafine powder and fine powder of D. candidum have certain preventive effect on photoaging,and the effect of ultrafine powder is better than that of fine powder. Ultrafine powder may down-regulate the expression of type Ⅲ collagen,AP-1 and MMP-1 by up-regulating type Ⅰ collagen. Inhibition of collagen degradation plays a role in preventing photoaging.

Objective: To investigate the difference of concentrations of specialized pro-resolving mediators (SPMs) derived from fatty acids in eosinophilic chronic rhinosinusitis with nasal polyps (ECRSwNP) and non-eosinophilic chronic rhinosinusitis with nasal polyps (nECRSwNP). Methods: A total of 36 patients with bilateral chronic rhinosinusitis with nasal polyps (CRSwNP) who underwent endoscopic nasal surgeries in Peking Union Medical College Hospital from May 2019 to September 2020 were enrolled, including 27 males and 9 females, with the age from 13 to 67 years. There were 23 cases of ECRSwNP and 13 cases of nECRSwNP. At the same time, 12 control subjects were enrolled. The concentrations of multiple SPMs, including lipoxins (LXA4 and LXB4), resolvins (RvD1, RvD2, RvD3, RvD5 and RvE1), protectins (PDX) and maresins (Mar-1) in nasal polyps with different histological subtypes and normal nasal mucosa were analyzed using liquid chromatography-tandem mass spectrometry. The concentrations of SPMs between groups were compared using Mann-Whitney U test. Spearman's rank correlation coefficient was used to measure the correlation between the concentrations of SPMs in nasal polyps and tissue eosinophil counts. Results: The concentrations of RvD2, RvD3, RvD5, LXA4, LXB4, Mar-1 and PDX in ECRSwNP group were significantly higher than that in controls (Z value was -2.276, -2.313, -3.371, -2.094, -2.051, -3.104 and -2.294, respectively, all P<0.05). The concentrations of RvD2, RvD5, Mar-1 and PDX in ECRSwNP group were significantly higher than those in nECRSwNP group (Z value was -2.175, -2.289, -2.243 and -2.124, respectively, all P<0.05). There was no significant difference in all these SPMs between nECRSwNP and controls (all P>0.05). The concentrations of RvD2, RvD3, RvD5, LXB4, Mar-1 and PDX in nasal polyps correlated positively with tissue eosinophil counts (r value was 0.443, 0.436, 0.371, 0.502, 0.340 and 0.386, respectively, all P<0.05). Conclusions: A varienty of SPMs are elevated in ECRSwNP. Dysregulation of fatty acid metabolism might play an important role in the chronic inflammation of ECRSwNP.
