Chinese Journal of Biochemical Pharmaceutics 2014;(3):140-142
Objective To analyze the clinical efficacy of compound 18 norgestrel combined with estrogen in treatment of dysfunctional uterine bleeding. Methods 78 cases of patients with dysfunctional uterine bleeding in Beijing Ji Shui Tan Hospital and Dongguan city people's hospital of guangdong Province were divided into control group (n=39)and observation group (n=39)by using randomized single-blind allocation. The control group was only given estrogen,the observation group was used compound 18 norgestrel combined with estrogen. The clinical efficacy of the two groups was compared. Results 31 cases were cured and 7 cases were valid of the study group,the total effective rate was 97.4%,significantly higher than the control group's total efficiency of 71.8%,the difference was statistically significant (P<0.05). Each index of observation group and the control group were improved after treatment,the difference was statistically significant (P<0.05 );After treatment,the menstrual cycle in observation group was (29.7 ±7.1)d,the menstrual period was (5.6 ±0.5)d,hemoglobin content was (135.5 ±21.7)g/L,endometrial thickness was (0.63 ±0.15)mm, significant changes than the control group,the difference was statistically significant (P<0.05 ). Conclusion Compound 18 levonorgestrel combined with estrogen has a better effect in patients with dysfunctional uterine bleeding and it can significantly improve patients'hemoglobin,the menstrual cycle and the uterus film thickness and other indicators which is worth promoting in clinical.

Objective To evaluate the clinical effect of thrombolysis combined with prostaglandin El (PGE1) in the treatment of patients with acute pulmonary thromboembolism (APTE).Methods According to the digital table,88 patients with APTE corresponding to thrombolytic therapy were randomly divided into the simply thrombolytic group(49 cases) and the joint PGE1 group(39 cases).The simply thrombolytic group were given conventional thrombolysis,and the joint PGE1 group were given thrombolysis combined PGE1 therapy.The levels of PaO2,PaCO2,pulmonary artery systolic pressure(PAsP),cardiac troponin I(cTNI),B-type natriuretic peptide(BNP) were monitored,and the clinical efficacy was evaluated.Results After the treatment,the levels of PAsP,cTNI,BNP of the joint PGE1 group were better than those of the simply thrombolytic group(t =2.173,2.349,2.495,all P <0.05).The clinical effective rate of the joint PGE1 group was 82.1%,which was significantly higher than that of the simply thrombolytic group (59.2 %) (χ2 =5.339,P < 0.05).The critical event occurrence of the joint PGE 1 group was 7.7 %,which was significant lower than that of the simply thrombolytic group (24.5 %) (χ2 =4.333,P < 0.05).Conclusion Thrombolysis combined PGEI therapy may be more effective in reducing pulmonary artery pressure,protecting myocardia,improving the right heart function than only thrombolysis,and thus improve clinical symptoms and short-term prognosis in the APTE patients.

Objective To investigate the effect of inhaled pravastatin on the acute inflammation of lung in smoked rats.Methods 32 male SD rats were randomly divided into four groups(n=8 per group),as the controls,cigarette-smoking exposure group,saline or pravastatin treatment groups.The rats in the control group were treated routinely,the other groups were exposed to cigarette smoking for one week.Rats in saline or pravastatin group were treated with saline or pravastatin inhalation respectively.During smoking exposure period rats were weighted before and after the treatment,executed at day eight,blood,bronchoalveolar lavage fluid(BALF),and lung tissue were collected.The morphological alternations of lung tissue were observed.Total cell numbers in BALF were counted.Enzyme-linked immunosorbent assay(ELISA) was used to detect the levels of serum IL-10 and IL-17 content.Results The increase of body weight of smoke-exposed rats were less than that of the controls.In smoking-exposed rats,acute inflammatory changes were remarkable in the lung.The total cell numbers in BALF and levels of IL-10 were increased significantly(P<0.05).These changes were mitigated in pravastatin treated rats and an IL-10/IL-17 rebalance was observed.Conclusion Inhalation of pravastatin sodium has a certain inhibitory effect on cigarette smoke-induced acute lung inflammation in rats.

Cationic polymers are being developed quickly as gene delivery vectors. For in vivo gene delivery, the cationic polymers are usually further modified by hydrophilic polymer grafting or ligand conjugation, which have been shown to increase the vector stability, gene delivery efficiency and specificity greatly. Some previous research had shown that modified hydrophilic polymer may partly shield the targeting ligand and result in poor delivery specificity. Developing a method to evaluate the influence of PEG modification on targeting delivery is particularly critical to cationic polymer design and gene therapy development. One of most commonly used cationic polymer polylysine (PLL) was chosen as a model. Targeting ligand epidermal growth factor(EGF)was conjugated with PLL to form PLL-EGF. Then hydrophilic polymer polyethylene glycol (PEG) with molecular mass 7 000 and 20 000 were used to modify PLL-EGF respectively to generate PEG7000-g-PLL-EGF and PEG20000-g-PLL-EGF. In BIAcore experiments, epidermal growth factor receptor (EGFR) was conjugated onto BIAcore chip and various PEG modified PLL-EGF solutions were flowed over the chip. By observing the change of RU value, the specific interaction of EGF to EGFR was compared. Compared with PLL-EGF, PEG modified PLL-EGF showed lower association rate and higher disassociation rate to EGFR. Furthermore, compared to PEG7000 modified PLL-EGF, PEG20000 modified PLL-EGF got lower association rate and higher disassociation rate to EGFR. The Scatchard analysis results showed that the interactions between EGFR and PLL-EGF or PEG-PLL-EGF are non-linear. It can be concluded that PEG modification indeed reduced the association rate and enhanced the dissociation rate of EGF to EGFR. The length of PEG chain was also a key factor to influence interaction between ligand and receptor. The results showed that it was critical important to evaluate the influence of PEG modification on delivery specificities. The BIAcore method developed in this paper can successfully evaluate the influence, which would be important for cationic polymer design and its application as potential non-viral gene delivery vectors.

Kaino-sinus syndrome is one new complication of endoscopic sinus surgery. The patient had an operation of endoscopic surgery, because he was suffered from an illness of frontal nasal inverted papilloma again. After operation he was suffering pain in left epicanthal folds and frontal part, and had dry scab in nasal cavity when he breathed cold air. The symptoms could relieve by blocking prenaris. We found he had a big aperture of frontal sinus and dry scab in nasal endoscopic examination. His symptoms disappeared after cleaning and washing accessory nasal cavity by salt water.

Objective: To investigate the immune regulation mechanism and anti-inflammatory effect of ω-3 fatty acids on sepsis patients.Methods: Totle 18 patients were divided into two groups,therapy group and control group. The control group was given routine therapy while the theray group was given routine therapy and fish oil.The expression of HLA-DR on peripheral monocytes was measured by flow cytometry at the beginning and 5 d during therapy, in parallel with serum c-reactive protein(CRP),interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),and severity of the disease(APACHE Ⅱ score),serum and oxygenation index(PaO2/FiO2)Results: Compared with conventional group,serum concentration of CRP, IL-6 and TNF-α in patients of therapy group were significantly reduced,and oxygenation index improved. There was no difference in the expression of HLA-DR and APACHE Ⅱscore between two groups.Conclusion:Fish oil can decrease the elevated mediators of inflammation on sepsis patients,and can't regulation the expression of HLA-DR on peripheral monocytes.
