International Eye Science 2015;(2):323-325
To explore the feasibility, safety and effect of the full-thickness lamellar keratoplasty for the treatment of pseudomonas aeruginosa corneal ulcer.METHODS: Based on a retrospective non-controlled study, 25 patients were given the full-thickness lamellar keratoplasty for clinical diagnosis of pseudomonas aeruginosa infection and corneal ulcer medication conventional anti-gram-negative bacteria. Routine follow-up were carried out at postoperative 1wk; 1, 3, 6, 12, 18mo to observe the situation of corneal epithelial healing, recurrent infection, immune rejection, graft transparency and best corrected visual acuity, etc. At the 6 and 12mo postoperative, corneal endothelial cell density was reexamined. RESULTS: No patients because of Descemet's membrane rupture underwent penetrating keratoplasty surgery: One only in cases of bacterial infection after 1mo, once again did not cultivate a culture of bacteria pseudomonas aeruginosa, and the remaining 24 cases average follow - up 14 ± 6mo, corneal graft were transparent, the cure rate was 96%. At the sixth month after surgery, there were 16 cases of eye surgery best corrected visual acuity ≥4. 5, of which 3 cases ≥4. 8. At the sixth month after surgery, the average corneal endothelial cell density 2 425 ± 278/mm2; At 12mo postoperatively, it was 2257± 326/mm2.CONCLUSlON: Full-thickness lamellar keratoplasty is an effective method of pseudomonas aeruginosa infection in the treatment of corneal ulcers, corneal drying material glycerol can be achieved by visual effects.

In the framework of ensemble, a partial least squares(PLS) regression ensemble algorithm in subspace(MIESPLS), which is the combination of bootstrap and variable selection based on mutual information(MI), was proposed. The key of the proposed algorithm is to introduce the diversity of member models by bootstrap re-sampling on the training set and the subsequent MI calculation. Each time, those variables whose MI are lower than a defined threshold are first eliminated;then, a member model can be trained on a smaller subspace of original spectral variables. Two kinds of model fusion strategies, i.e., simple average fusion(SAF) and weighted average fusion(WAF), were adopted and compared. By two experiments concerning quantitative application of near-infrared(NIR) spectroscopy, MISEPLS is confirmed to be superior to the full-spectrum PLS and MIPLS method, i.e., PLS combined with MI-induced variable selection. The proposed MISEPLS can produce a more accurate and robust calibration model, but without increasing the complexity.
4.Advances of the anti-tumor research of metformin.
Acta Pharmaceutica Sinica 2015;50(10):1210-1216
Metformin is the most commonly prescibed drug for type 2 diabetes mellitus as it is inexpensive, safe, and efficient in ameliorating hyperglycemia and hyperinsulinemia. Numerous epidemiological studies indicate that diabetic population is not only at increased risk of cardiovascular complications, but also at substantially higher risk of many forms of malignancies. Meanwhile, epidemiological and clinical observation studies have shown that metformin use reduces risk of cancer in patients with type 2 diabetes mellitus and improves prognosis and survival rate of the cancer patients. Furthermore, metformin has been used for cancer therapy in clinical trials. Thus, metformin is emerging as a new cancer therapy or adjuvant anticancer drugs. This review summarizes recent progress in studies of metformin use and its molecular mechanism.

5.Analysis on the Law of Application of Drugs in Commonly-used Chinese Herb Complex Prescriptions for Treatment of Hypetension
Journal of Traditional Chinese Medicine 1993;0(05):-
Objective:To study on the law of application of drugs in complex prescriptions of Chinese herbs for treatment of hypertension. Methods:The author read 1 102 papers about treatment of hypertension from 1980 to 2003,collected 1 191 complex prescriptions of Chinese herhs,established Access database of complex prescription of Chinese drugs for treatment of hypertension,and analyzed the law of application of drugs in complex prescription of Chinese herbs for treatment of hypertension by combination of Access, Excel with VB programming based on the database.Results:In the 1 191 complex prescriptions of Chinese herbs,394 herbs were used 11 371 times.Among them,the drugs for reinforcing deficiency,clearing heat,calming the liver to stop the wind,and activating blood stasis and removing blood stasis are main.192 pairs of drugs were used over 50 times,with 21 traditional drug pairs of Chinese medicine,and combination principles of the first 10 pairs with the highest application frequency were analyzed by TCM combination theory.And there were 30 drug groups which were used for over 50 times,and prescription composition principles of the first 10 groups with the highest application times were analyzed by TCM composition theory.Conclusion:Large- scale data process with computer is an effective method for finding the law of application of drugs in Chinese complex prescriptions for treatment of hypertension.
6.Mechanism of Spontaneous Rupture of Hepatocellular Carcinoma
Chinese Journal of Bases and Clinics in General Surgery 2003;0(02):-
Objective To study the mechanism of spontaneous rupture of hepatocellular carcinoma(HCC).Methods Articles have been reviewed to find out the theory of spontaneous rupture of HCC.Results Researchful results suggested that the injury of small arteries was usually followed in patients of spontaneous rupture of HCC.In this review,the immune complex,which composed of hepatitis B virus e antigen,complement C1q and immunoglobulins,was found deposited in the elastic membrane of arteries.Likely as a result of immune complex deposition,vascular injury occurs mainly in the small arteries where the deposition of immune complex was present.The small arteries in which immune complex deposited are readily injuried and cause hemorrhage and rupture of HCC during vascular load increase. Conclusion We would conclude that immune complex deposition in vessel wall led to the small arteries injury may be the factor involved in the pathogenesis of spontaneous ruptured HCC.

10. Arthroscopic treatment of schatzker type III tibial plateau fractures with hydroxylapatite rods: 6-month follow-up
Chinese Journal of Tissue Engineering Research 2020;25(10):1571-1576
BACKGROUND: The clinical treatment of Schatzker III tibial plateau fracture is different, including internal fixation, external fixation and arthroscopy. OBJECTIVE: To investigate the effect and influencing factors of arthroscopic treatment of Schatzker type III tibial plateau fracture with nano hydroxylapatite rod. METHODS: Totally 36 cases of Schatzker type III tibial plateau fractures admitted to Hebei Provincial People’s Hospital from July 2017 to July 2019 were enrolled, including 25 males and 11 females, aged 20-57 years. Among them, 18 patients in the observation group received minimally invasive arthroscopic hydroxylapatite rod implantation and 18 patients in the control group received conventional open plate and screw fixation. After 6 months of follow-up, complications and fracture healing time were recorded. Pain was assessed by visual analogue scale score. Knee function was assessed by HSS score. Excellent and good rate was assessed by Lysholm score. The effects of single factors such as age, sex, combined meniscus and ligament injuries, operation time and intraoperative blood loss in the observation group on the efficacy of the postoperative knee joint were analyzed by single factor analysis. The trial was approved by the Ethics Committee of Hebei Provincial People’s Hospital. RESULTS AND CONCLUSION: (1) The incidence rate of postoperative complications such as deep venous thrombosis and traumatic arthritis in the observation group was lower than that in the control group (P < 0.05). (2) The healing time of the observation group was shorter than that of the control group (P < 0.05). The excellent and good rate of clinical treatment was higher in the observation group than that of the control group (P < 0.05). (3) The visual analogue scale scores of the observation group were lower than those of the control group at 1 day, 1 week, 1 and 3 months after operation (P < 0.05). The HSS scores of knee joint function in 1, 3 and 6 months after operation were higher in the observation group than those in the control group (P < 0.05). (4) The single factor analysis showed that the postoperative effect of patients with age < 50 years was better than that of patients with age ≥ 50 years (P < 0.05). (5) The results showed that the minimally invasive treatment of Schatzker type III tibial plateau fracture with nano hydroxyapatite rod under arthroscope could promote fracture healing, alleviate pain and promote joint function recovery, in which the age was an independent factor affecting the postoperative effect.
