Biotechnological pharmaceutics is an important course for pharmacy undergraduates , however there are many problems in current curriculum design and teaching methods. With the advantage of our platform National Engineering Research Center of Immunological Products, we tried to carry out the teaching reformation based on Excellent Engineer Education and Training Plan. We optimized the curriculum standards and teaching design, highlighted the combination ofBiotechnological pharmaceuticsand Engineering, strengthened the experiment teaching, tried the reformation of teaching method such as flipped classroom and PBL, strengthened the cultivation of innovative thinking and scientific research ability. Our teaching reformation is beneficial to cultivating the compound talents in the field of biotechnological pharmaceutics.

Objective To investigate the effects of different CO2 pneumoperitoneum pressures on gastric cancer cells' growth and proliferation in nude mouse model of implanted tumor. Methods Human gastric cancer cell lines MNK-45 were exposed under 0、10、12 and 15 mm Hg CO2 pneumoperitoneum for 4 hrs respectively. 2 × 106 processed cells were inplanted into nude mice subcutaneously. Three weeks later, mice were sacrificed and the weight and bulk of the tumor measured. Then we observed the transplantation tumor by HE stain and Ki-67 stain. Results There was no significant difference in tumor's growing time, bulk and weight between 0, 10, 12 mm Hg CO2 pneumoperitoneum groups (7. 8 d, 7. 2 d, 7. 8 d; 1. 2 cm3, 1. 3 cm3, 1. 3 cm3; 1.5 g, 1. 9 g, 1. 6 g)and the control group (7. 3 d, 1. 2 cm3, 1.4 g) (P > 0. 05 ). The growing time of tumor in 15 mm Hg CO2 pneumoperitoneum (12. 5 d) was obviously longer than the control group ( P < 0.05 ) , the bulk and weight of tumor in 15 mm Hg CO2 pneumoperitoneum (0. 5 cm3, 0. 5 g) group significantly decreased compared with the control group (P <0.05). The positive rate of Ki-67 in 15 mm Hg CO2 pneumoperitoneum (27. 5% ) group was obviously lower than the control group (59.6%) (P<0.01). However, there were no significant differences between 0, 10, 12 mm Hg CO2 pneumoperitoneum groups (61.2%, 60.5%, 63.4%) and the control group (P > 0.05). Conclusion Clinically adopted CO2 pneumoperitoneum pressures have no significant effect on gastric cancer cells growth and proliferation.

With the development of instrumentation and surgical techniques,laparoscopic gastrectomy has become a promising surgical option for the treatment of gastric cancer.While laparoscopic gastrectomy is high technique-demanding,which hampered its popularization.Compared with traditional laparoscopes,Da Vinci surgical system has more special features,such as flexible robotic arms and three-dimensional imaging,which facilitates surgical procedures.A 58-year-old male patient with gastric cancer underwent Da Vinci surgical system-assisted radical total gastrectomy at the Southwest Hospital in March 2010.The mean operation time and blood loss were 270 minutes and 60 ml,respectively,and the number of dissected lymph nodes was 21.The short-term clinical effect was perfect without postoperative complications.Da Vinci surgical system-assisted radical total gastrectomy is safe and feasible,and it brings challenges to conventional laparoscopes.

Objective To establish a rat model of cardiac hypertrophy induced by isoproterenol(ISO),and to study its basic characteristics . Methods Cardiac hypertrophy was induced in rats with ISO. The model rats received subcutaneous injections of 5 mg/kg ISO every day for 14 days. Results The heart weight/body weight and left ventricular weight/body weight ratios in model rats were significantly increased. The serum hydroxyproline level was significantly increased ,the superoxide dismutase level was significantly decreased ,and the malondialdehyde level was sig?nificantly increased in model rats. Conclusion The rat model of cardiac hypertrophy is successfully created by subcutaneous injection of ISO for 14 days. This model can be used in study of the mechanism of cardiac hypertrophy.

? AlM: To evaluate the clinical application of simply performing phacoemulsification or combining intravitreal Ranibizumab injection in the treatment of cataract combined with diabetic retinopathy.
?METHODS:Forty-six patients (46 eyes) were recruited in this study. All of the patients were non-proliferative diabetic retinopathy without significant macular edema. They were randomly divided into two groups, the control group simply performed phacoemulsification, while the study group performed intravitreal Ranibizumab injection and phacoemulsification. Observation of indicators included the condition of best corrected visual acuity (BCVA), intraocular pressure, macular retinal thickness and complication at preoperative and postoperative 1, 6mo.
? RESULTS: BCVA and macular retinal thickness of patients in two groups had no differences in the preoperative and postoperative 1mo. At postoperative 6mo, the BCVA of the study group was better than that in the control group, while its macular retinal thickness was thinner than that in the control group (P<0. 05). The ratio of macular edema ( central macular thickness was >60μm than that in control group) was 13. 0% eyes in the study group which was significantly lower than the control group (47. 8%;P = 0. 033). The complications was no significant differences in two groups and neither occurred severe complications.
?CONCLUSlON: lntravitreal Ranibizumab injection can reduce the development of macular edema and improve the BCVA after phacoemulsification.

AIM:To assess changes of tear film function in patients after pterygium excision combined with amniotic membrane transplantation.
METHODS:Totally 126 patients with pterygium excision with amniotic membrane transplantation from January 2011 to November 2013 were entered in the study. The tear breakup time ( BUT) , the Schirmer I test ( SⅠt) and tear ferning test ( TFT ) were elevated in the patients before and after pterygium excision combined with amniotic membrane transplantation. The examnation times were 1d before surgey, 1wk, 1, 2mo after surgery. Operation eyes were studied group, while opposite healthy eyes as control group.
RESULTS: Compared with the control group, BUT and TFT were significantly different in the eyes with pterygium (P<0. 05); However, no obvious difference was detected in the results of SⅠt (P>0. 05). The results of BUT and TFT at 1mo after surgery in study group were significantly better than 1wk (P<0. 05), while no significant difference compared with 2mo (P>0. 05); The tear film stability in the study group at 1wk after surgery was still inferior to the control group (P<0. 05) and there was no significant difference at 1, 2mo after surgery (P all>0. 05). SⅠt results did not differ between the different examination times(P>0. 05).
CONCLUSION:Tear film stability was broken in the eyes with pterygium. Pterygium excision combined with amniotic membrane transplantation can obviously restore the tear film function into normal state, and the tear film function could reach steady-state 1mo after surgery.

Objective:
To discuss the difference between pyrophosphoric acid method and infrared spectrophotometry for the determination of silica content in dust.
Methods:
The content of silica in the laboratory comparison samples organized by CDC Occupational Health Institute in China in 2018, and purchased quality control samples were determined by pyrophosphate method. Meanwhile, the samples were qualitatively and quantitatively analyzed by infrared spectrophotometry, and the results obtained by the two methods were compared.
Results:
Four samples (062C1、062C2、GDOHZKTG012-1、GDOHZKTG012-2) were detected by pyrophosphate method and infrared spectrophotometry. The results of pyrophosphate method were 55.49%, 5.24%, 4.90% and 54.72%, respectively. The results of infrared spectrophotometry were 0.91%, 1.87%, 1.29% and 1.16% respectively.
Conclusion
The content of silica in dust determined by pyrophosphate method is higher than that by infrared spectrophotometry.
