OBJECTIVETo investigate the distribution of monocyte subpopulations and the changes of Toll-like receptor 4 (TLR4), CD163 and CD36 expressions in the peripheral blood of patients with hyperlipidemia of phlegm-stagnancy obstruction syndrome pattern (HLE-PSO), and to evaluate the intervening effects of Qutan Huayu Jiedu (QHJ) herbs on these parameters.

METHODSMonocytes in the peripheral blood were sorted using flow cytometry into 3 subpopulations: the CD14high CD16- (Mo1), the CD14high CD16+ (Mo2a) and the CD14low CD16+ (Mo2b) subpopulation. The percentages of various monocyte subpopulations in 83 patients and 42 matched healthy controls were determined and the levels of their surface receptors TLR4, CD163 and CD36 expressions were assayed with flow cytometer. Furthermore, patients allocated in the tested group (10 patients) and the control group (11 patients) were treated with QHJ Herbs and Qutan Huayu (QH, removing Phlegm and dissolving stagnancy but without detoxication) herbs respectively. The changes of monocyte subpopulations percentage and TLR4, CD163 and CD36 expressions were determined 4 weeks after they received treatment.

RESULTSPercentage of Mo2a subpopulation was significantly higher in HLE-PSO patients than the normal range (5.35 +/- 2.57 vs. 3.09 +/- 2.38, P < 0.01), but the deviation of the other two subpopulations in percentage was insignificant. The TLR4 expression on Mo1 monocyte in patients was lower than normal (50.73 +/- 24.45 vs. 69.92 +/- 21.06, P < 0.01), while CD163 and CD36 expressions of all three subpopulations in patients were similar to those in healthy persons respectively. After 4 weeks of treatment, a significant lowered Mo2a proportions were observed in the tested group (3.73 +/- 1.05 vs. 5.50 +/- 2.06, P = 0.043); but not in the control group (4.20 +/- 1.81 vs. 5.65 +/- 1.89, P = 0.097), while the levels of TLR4, CD163 and CD36 were not significantly altered after treatment in both groups.

CONCLUSIONSThe elevated proportions of Mo2a subpopulation and the lowered TLR4 expression in Mol subpopulation are the characteristic changes in HLE-PSO patients, which might be related with the hyperlipidemia caused immune injury in patients. QHJ herbs could effectively improve the disproportion of Mo2a subpopulation.

AIM: To explore the long-term efficacy of Q-factor guided laser epithelial keratomleusis ( LASEK ) for myopia and astigmatism with positive Q-factor.
METHODS: There were 158 eyes which were myopia and astigmatism with positive Q- factor taken in two groups randomly: 86 eyes accepted Q - factor guided LASEK as observation group and 72 eyes accepted routine LASEK as control group. The difference between the two groups about all data was similar. The uncorrected visual acuity ( UCVA ) and the best corrected visual acuity ( BCVA ) as well as diopter, ocular tension, corneal topography, Keratometry value K, aspherical factor Q, Higher-order aberrations ( HOA ) , corneal thickness by ultrasound and, contrast sensitivity ( CS ) , Haze were examined and compared before and after surgery. All the cased were followed up for 14d, 1, 3, 6, 12mo. And there were no statistical difference among the data before surgery.
RESULTS: After 12mo there were no statistical difference between the two groups about UCVA and BCVA. But the safety index of observation group was 1.10, that of control group was 1. 07. The validity index of observation group was 1. 06, that of control group was 0.99. The HOA of observation group was 0. 45±0. 17μm, and that of control group was 0. 72±0.25μm, there was statistically significant difference (t=-8. 193,P=0. 000). Q factor of observation group was 0. 41±0. 17, that of control group was 0. 77±0. 22, there was significant difference (t=11. 377,P = 0. 028). The contrast sensitivity of 3mo post surgery of patients in the observation group returned to the level of before surgery. But in the control group the contrast sensitivity of the patients did not returned until 6mo.
CONCLUSION:Q-factor guided LASEK for myopia and astigmatism with positive Q-factor is stable, safe and effective. The operation allow for reducing the high order aberrations, maintaining the most asphericity of cornea, saving more in corneal tissue, which cause faster recovery of contrast sensitivity, less haze and better visual quality.

Objective To evaluate the expression of Toll-like receptor(TLR)on the monocyte- derived dendritic cells(DC)from chronic hepatitis B(CHB)patients and to analyze the expression pro- file and significance of the TLR such as TLR3,TLR4,TLR?,TLR8 and TLRg,which are associat- ed with immune response to viral infection.Methods Peripheral blood mononuclear cell(PBMC) centrifugated by the hydroxyethyl starch(HES)centrifugation were cultured and induced into DC by granulocyte-maerophage colony stimulating factor(GM-CSF)and interleukin-4(IL-4),and their mor- phology and phenotype were detected by the inverted microscope and flow cytometry respectively. Monocyte-derived DC were obtained from 10 chronically hepatitis B virus(HBV)-infected patients and 15 healthy volunteers.TLR3,TLR4,TLR7,TLRS,TLR9 expression on immature and mature DC were analyzed by FACS Calibur.DC was pulsed with HBcAg on day 3 and 5,then DC maturation and ability to process HBcAg and to stimulate autogeneic T cells were evaluated.Results Monocyte- derived DC developed different TLR expression patterns as they went through different maturation stages.TLR7,TLR8 expressions on immature DC and TLR3,TLR7 expressions on mature DC were lower in CHB than in control(for TLR7,TLR8 expression on immature DC:75.9%,1.0%vs 98.4%,15.4%,P

Objective To establish a method for detecting HBV cccDNA in hepatocytes of chronic hepatitis B patients.Method 21 liver biopsies from the hepatic operation patients in the hospital of jiangsu province,concluding 19 HBV chronic infected patients (10 HBeAg positive patients and 9 HBeAg negative patients) and 4 uninfected patients,HBV DNA(+) serum of hepatitis B patients was thought as rcDNA.To use proteinase K to release HBV cccDNA and genomic DNA,then divide the cell lysis solution into two parts,one for detecting HBV cccDNA,the other for detecting the number of ?-Globin as internal control. Nucleic acid for detecting HBV cccDNA extracted by phenol-chloroform was digested by plasmid-safe ATP dependent DNase which was applied to digest the single strand DNA in rcDNA and ssDNA,then was quantitated by the primers spanning across the nick and SYBR Green Ⅰ dye.The specifity of PCR production was confirmed by the sequence analysis and rcDNA comparison.The significance of the difference of HBV cccDNA level between HBeAg(+) and HBeAg(-) group was analyzed by two group t test.Results The agarose gelelectrophoresis showed the molecular weight of the PCR production was about 350bp.The coincidence rate of PCR production and goal fragement was nearly 99% by sequence analysis.The result of PCR detection of rcDNA group was negative.The positive rate of HBV cccDNA of liver biopsies of HBeAg (+) patients detected by this method was 100%,the level of HBV cccDNA in the liver biopsies of HBeAg (+) patients was higher than HBeAb(+) patients.Conclusions The specificity of the method is proved by agarose electrophoresis,gene sequencing of the PCR product and rcDNA comparison.The quantitative method that use SYBR Green Ⅰ dye and ?-Globin as internal control is more specific,sensitive and economical,and more suitable for clinical purpose.

AIM: To observe and analyze the changes of macular retina thickness in children with occult high myopia and its influencing factors.

METHODS: A prospective, non-randomized, contemporaneous controlled trial. From September 2019 to September 2020, 56 children(110 eyes)who first visited the ophthalmic clinic of the Affiliated Hospital of Chengde Medical College without any myopia correction training were enrolled in this study. According to the clinical manifestations of myopia in children, they were divided into occult high myopia group(27 cases, 52 eyes)and control group(29 cases, 58 eyes, children with common myopia). The retina thickness in each macular area was compared between the two groups, and we will analyze the correlation between macular fovea mean retinal thickness and baseline data in children with occult high myopia.

RESULTS: The average retinal thickness of 9 macular regions in the occult high myopia group was thinner than that in the control group, and there were significant differences in the macular fovea, the blow and temporal side of the outer ring area of macular fovea(P<0.05). Compared with the control group with the same spherical equivalent, there was significant difference in area that the temporal side of the outer ring of the macular fovea in the occult high myopia of 0.00D to -1.00D and the fovea in the occult high myopia group of >-2.00D to -3.00D(P<0.05), but there was no significant difference among the other regions(P>0.05). Pearson correlation analysis results showed that the average retinal thickness under macular fovea in children with secretive high myopia had no significant correlation with gender, age, eye axis, intraocular pressure and corneal curvature(P>0.05), but was negatively correlated with diopter(r=-0.201, P<0.05).

CONCLUSION: The thickness of macular retinal in children with occult high myopia is thinnest under macular fovea and the thickest above macular fovea in inner ring area. The average retinal thickness in each region of the macular is thinner than that in the common myopia children with the same diopter. The mean retinal thickness of macular fovea is negatively correlated with the diopter.

Objective To summarize our experience of simple neuroendoscopic endonasal transsphenoidal surgery for pituitary adenoma and discuss its advantages. Methods Forty-two patients with pituitary adenoma diagnosed by CT or MRI detection (diameters of the tumor: <1cm in 11 patients, 1-2cm in 11, 2-3cm in 18, >3cm in 8) were treated by simple neuroendoscopic endonasal transsphenoidal surgery. During transsphenoidal approach, the nasal mucosa was not incised and the nasal septum and median nasal conchae were not dissected. Under neuroendoscopic assistance, the anterior wall of the sphenoidal sinus and sellae base was opened directly and adenoma resection was performed. Results All the patients were followed up for 1-12 months. By postoperative MRI detection, adenomas were resected completely in 38 patients, subtotally in 4 cases. Rapid improvement of vision was noted postoperatively. The increased hormonal level in 18 of 22 patients was decreased to normal postoperatively and another 4 cases improved clinically in serum hormone levels during follow-up. Postoperative transient CSF leakage occurred in 6 cases and transient diabetes insipidus in 23 cases. Conclusions The simple neuroendoscopic endonasal transsphenoidal surgery for pituitary adanoma is safe, time-saving and without severe complications, provides a satisfactory deep illumination and a panoramic operative field. The injury to the patient and postoperative complications are less. The clinical application of the neuroendoscopy for pituitary adenoma is worthy of recommending.
