Under the guidance of the Liu's theory of kidney deficiency and incubative pathogen, the authors point out that for understanding the incubative pathogen of chronic hepatitis B (CHB) you should grasp the essence of the pathogenesis, kidney deficiency. For chronic hepatitis B, it is easier to be understood and conforms to pathological characteristics of chronic hepatitis B. The property of the incubative pathogen can not be restricted to that the incubative cold changes to warm, it should be understood as epidemic heat and epidemic toxin. Therefore, the authors first put forward this hypothesis: the pathogenesis of chronic hepatitis B is kidney deficiency and damp-heat toxic pathogen incubating in liver and blood. And based on the hypothesis a comprehensive therapy including clearing away heat, expelling pathogenic factors, promoting blood circulation and tonifying the kidney is introduced.

International Eye Science 2020;20(2):286-289
AIM: To study the effect of cyclosporine A combined with glucocorticoid in the treatment of corneal ulcer.
METHODS: From May 2015 to May 2018, 200 patients with corneal ulcer were selected and divided into combined group and glucocorticoid group according to different treatment methods, 100 cases each. In the combined group, cyclosporine A was given on the basis of the glucocorticoid group. C-reactive protein(CRP)and interleukin-6(IL-6)were measured to evaluate the quality of life, clinical symptoms, treatment efficiency, recurrence rate and incidence of adverse reactions.
RESULTS: After treatment, the levels of CRP and IL-6 in the two groups were lower than that before treatment, and the quality of life was higher than that before treatment(P<0.05). The level of CRP and IL-6 in the combined group was lower than that in the glucocorticoid group, and the quality of life was higher than that in the glucocorticoid group(P<0.05). The time of conjunctival hyperemia, ophthalmalgia and ulcer healing in the combined group were lower than those in the glucocorticoid group(P<0.05). The effective rate of combined group was higher than that of glucocorticoid group, and the recurrence rate of combined group was lower than that of glucocorticoid group(P<0.05).
CONCLUSION: Cyclosporine a combined with hormone is effective in the treatment of corneal ulcer, which can improve the clinical symptoms, reduce the inflammation, improve the quality of life and reduce the recurrence.
3.Research progress and clinical application of the third- generation sequencing techniques.
Chinese Journal of Biotechnology 2022;38(9):3121-3130
The Sanger sequencing techniques, also known as the first-generation sequencing techniques and the gold standard of sequencing, have promoted the completion of "working draft" of the human genome, but the disadvantages of low throughput and high cost limit its large-scale application. The second-generation sequencing techniques, also known as the next-generation sequencing techniques, have widely used in basic research and clinical application because of its high throughput and low cost, but the short reads has always been an unavoidable shortcoming. Then, the emergence of the third-generation sequencing techniques, with the long reads, provides new technology selection for the analysis of complex repetitive regions on genome sequences and the assembly of high-quality genomes. In recent years, the third-generation sequencing techniques have been further developed, and have gradually demonstrated the clinical application value. This article reviewed the research progress and clinical application of the third-generation sequencing techniques.

BACKGROUND:At present, a heparin-coated extracorporeal circulation pipe is used widely, but the price is expensive and limits its wide application.
OBJECTIVE:To screen the optimal coating condition of oxidated sodium alginate as a coating material to coat the medical polyvinyl chloride pipe and to evaluate the anticoagulant properties and the stability of the coated pipe.
METHODS:Oxidized sodium alginate was prepared with sodium periodate, and the mole ratio of sodium periodate and sodium alginate was 1:8, 1:10 and 1:12, respectively. Oxidized sodium alginate with different
degree of oxidation was coated on the surface of medical polyvinyl chloride pipes by chemical methods, then to select the best degree of oxidation. The optimal coating condition was screened through an orthogonal
experiment based on concentrations of sulfuric acid, polyethyleneimine and oxidized sodium alginate, and pH
value and temperature of oxidized sodium alginate. Additional y, the anticoagulant properties and expulsion rates of the prepared pipes were evaluated in comparison with the blank control group and heparin-coated group.
RESULTS AND CONCLUSION:The optimal oxidation degree for oxidized sodium alginate was 1:10 for the mole ratio of sodium periodate and sodium alginate. The best coating conditions were 50%concentrated sulfuric acid, 0.05%polyethyleneimine, 40 ℃ of reaction temperature, 2 g/L oxidized sodium alginate, and pH value=3.5. The oxidized sodium alginate coating group had a similar trend compared with heparin-coated group in the expulsion rate. The anticoagulant properties of oxidized sodium alginate coating group were little weaker than those of
heparin-coated group (P<0.05), but significantly better than those of the blank control group. The oxidized sodium alginate-coated extracorporeal circulation pipe has a good anticoagulant property and stability.

Objective To evaluate the early diagnosis value of MRI combined with DSA in cirrhotic nodules (regenerative nodules, dysplastic nodules) becoming small hepatocellular carcinoma. Methods 40 patients diagnosed as cirrhosis and whose liver nodules detected by ultrasound were followed up as MR dynamic study. All patients were followed up by three dynamic contrast-enhanced MR scanning once every 3 months,and the changes of cirrhotic nodules were observed and analyzed in the signal. If MRI suggested cancerous nodules cirrhosis, hepatic artery DSA would be carried out. Results 40 patients were followed up for 1.5 to 3 years,all patients MR nodules were found in liver regeneration. Follow-up process, the dysplastic nodules were founded in 28 cases and the small hepatocellular carcinoma were founded in 18 patients. 16 cases of 18 patients with small hepatocellular carcinoma carried out routine DSA all had typical of hepatic arterial blood supply and angiogenesis, and were given to Integrated Traditional and Western intervention simultaneously. Conclusion Combined use of MRI-DSA in the evaluation of cirrhotic nodules had a definite value, and could find smaller hepatocellular carcinoma,provide the basis for smaller hepatocellular carcinoma therapy.
7.Related factors in the development of anemia in preterm infants.
Chinese Journal of Contemporary Pediatrics 2008;10(5):589-592
OBJECTIVESTo investigate the related perinatal factors in the development of anemia of prematurity by a case-control study.
METHODSThe medical data of 165 preterm infants admitted to the department of neonatology in Peking University Third Hospital from January 2005 to December 2006 were retrospectively reviewed. The infants were classified into two groups: anemia and non-anemia (control). The factors associated with anemia of prematurity were identified.
RESULTSSixty-three preterm infants (38.1%) had anemia. The gestational age (32.5+/-2.0 weeks vs 33.7+/-1.9 weeks) and birth weight (1682.7+/-393.9 g vs 2041.1+/-510.1 g) of the anemia group were significantly lower than those of the control group (P<0.01). The blood loss from laboratory testing (12.4+/-6.5 mL/kg vs 6.6+/-3.6 mL/kg) and the duration of hospital stay (25.6+/-14.2 days vs 14.1+/-8.7 days) of the anemia group were significantly higher than those of the control group (P<0.01). More critically ill patients (33.3%) were noted in the anemia group compared with in the control group (9.8%) (P<0.01). In the anemia group, 44.4% of the mothers had preeclampsia but only 28.4% in the control group (P<0.05). Multiple factor logistic regression analysis revealed that the blood loss from laboratory testing was the only independent high-risk factor for anemia of prematurity. Compared with the preterm infants whose blood loss from laboratory testing was < 5 mL/kg, the OR values of the preterm infants whose blood loss was 5-10, 10-15 and > or = 15 mL/kg was 1.737 (95% CI: 0.699-4.316, P>0.05), 4.141 (95% CI: 1.573-10.905, P<0.01) and 32.267 (95% CI: 8.053-129.287, P<0.01), respectively.
CONCLUSIONSAnemia of prematurity is associated with gestational age, birth weight, duration of hospital stay, illness severity and maternal preeclampsia. The blood loss from laboratory testing is an independent risk-factor in the development of anemia of prematurity.
