This study was aimed to screen out an optimal pharmaceutical formulation of Wuji Gastric Floating Sus-tained-release Tablets. With multicomponents of release for index, the extra-floating ability of the tablets was stud-ied with the orthogonal test of four excipients, which were HPMC (K100M), PEG 6000, sodium bicarbonate and se-tanol. The results showed that the combined optimal pharmaceutical formulation was 35% HPMC, 5% PEG 6000, 10% sodium bicarbonate, 15% setanol, 10% MCC and 25% main drug. It was concluded that Wuji Gastric Floating Sustained-release Tablets had the characteristics of slow-release and long floating duration which comply with re-quirements of formulation design. This preparation technique is with good maneuverability.

OBJECTIVE To investigate the rescue and treatment of critical children with tracheobronchial foreign body. METHODS From June 2011 to June 2015,there were 2489 children with tracheobronchial foreign bodies treated in Children's Hospital of HeBei Province, among which 11critical children who were rescued as soon as they came to the hospital. The clinical data of the 11critical children were analyzed. RESULTS All the 11 critical cases endured dyspnea of third degree or more severe and presented severe hypoxia, in which 2 children had been performed tracheal intubation before they came to the hospital and 1 child even showed the symptom of respiratory and cardiac arrest. Among these critical cases, the foreign body was removed directly without anesthesia in 1 child. The other 2 children with severe pneumothorax, mediastinal emphysema and subcutaneous emphysema in neck and chest area were treated by excision and drainage of emphysema firstly, and then the foreign bodies were extracted through bronchoscope after general anesthesia. The another 8 children were performed operations of extraction of bronchial foreign body and then the foreign bodies were taken out. All the 11 critical children were rescued successfully and no death cases happened. CONCLUSION Rapid diagnosis and rapid removal of foreign bodies is the key to save the lives of critical children with tracheobronchial foreign bodies.

This article was aimed to study the multicomponent in vivo releasing rules of Zuojin Gastric Floating Sus-tained-release Tablet. Stomach contents of rabbits were collected at different times and then prepared into solutions for the study. The HPLC was used to establish fingerprints of each time and fingerprints of completely dissolved samples. The in vivo releasing rates were calculated. The evaluation was made on releasing behaviors among index components as well as between index components and preparations. The results showed that within 10 h, the f2 of berberine and limonin, rutaecarpine, preparation were 52, 61.5, 66.4, respectively. The f2 of limonin and rutae-carpine, preparation were 70, 46.5, 53.7, respectively. It was concluded that within 10 h, the releasing behavior of berberine and limonin, rutaecarpine, preparation was similar. The releasing behavior of rutaecarpine and limonin, preparation was similar. However, the releasing behavior of limonin and preparation was different.

· ATM:To analyze bacterial spectrum and drug sensitivity in conjunctival sac of cataract patients of Kazak.
· METHODS:A total of 538 cases of conjunctival sac secretion in cataract patients of Kazak were collected.The samples were cultured and their sensibilities to antibiotics were tested.
· RESULTS: The bacterial culture was positive in 214 cases.The positive rate was 39.8%. The variety of pathogenic bacteria were mainly made up of gram positive cocci ( 88.3%), and most of them were Staphylococcus epidermidis ( 66.4%), followed by Micrococcus(9.8%).Sex had no effect on conjunctival bacteria rate in the cataract patients of Kazak, while age, place of residence had an effect on camier rate. The camier rate of conjunctival bacteria was significantly higher in people over 60 years old than that in people with age between 40 to 59 years old.And the people from city had a significant lower bacteria positive rate than those from countryside and pastoral. Most of grams were sensitive to Vancomycin, Teicoplanin, Rifampicin, Duly cloth mildew mutual and Amikacin, the tolerance was less than 20%, and they usually had higher tolerance to Penicillin, Erythromycin, Tetracycline and Chloramphenicol (>70%) .
·CONCLUSlON:Gram positivecocci is the most common bacteria in conjunctival sac in cataract patients of Kazak. Staphylococcus epidermidis was most common, followed by Micrococcus.The germ-carrying rate of conjunctival SAC in Kazakh population is associated with the patient’s age and area of residence.The clinical use of antibacterial drugs should be strictly grasp the indications, to reduce the incidence of bacterial resistance.

OBJECTIVETo investigate the influence of seasons, blood types and semen parameters on the cryosurvival rate of frozen-thawed spermatozoa from sperm donors.

METHODSWe retrospectively analyzed the influence of seasons, blood types, abstinence period, semen volume, sperm morphology, and pre-freeze sperm motility and concentration on the cryosurvival rate of frozen-thawed sperm in 4 088 semen samples from Shaanxi Human Sperm Bank.

RESULTSThe cryosurvival rate of the post-thaw sperm was correlated negatively with the progressive motility of the pre-freeze sperm (r = -0.262, P < 0.01), but positively with pre-freeze sperm concentration (r = 0.247, P < 0.01), and it was significantly higher in the 6-day abstinence group ([70.2 +/- 5.4]%) than in the other abstinence groups (P < 0.01), so was it in the normal sperm morphology rate > 20% group ([71.4 +/- 5.1]%) than in the others (P < 0.01). The survival rate of the post-thaw sperm was not correlated with seasons, blood types, and semen volume (P > 0.05).

CONCLUSIONSperm motility, concentration and morphology and the abstinence period of sperm donors may be valuable predictors of the cryosurvival rate of post-thaw sperm, but no correlation was found between the survival rate and seasons, blood types and semen volume.

Since the initial observations of oral bacteria within dental plaque by van Leeuwenhoek using his primitive microscopes in 1680, an event that is generally recognized as the advent of oral microbiological investigation, oral microbiology has gone through phases of "reductionism" and "holism". From the small beginnings of the Miller and Black period, in which microbiologists followed Koch's postulates, took the reductionist approach to try to study the complex oral microbial community by analyzing individual species; to the modern era when oral researchers embrace "holism" or "system thinking", adopt new concepts such as interspecies interaction, microbial community, biofilms, poly-microbial diseases, oral microbiological knowledge has burgeoned and our ability to identify the resident organisms in dental plaque and decipher the interactions between key components has rapidly increased, such knowledge has greatly changed our view of the oral microbial flora, provided invaluable insight into the etiology of dental and periodontal diseases, opened the door to new approaches and techniques for developing new therapeutic and preventive tools for combating oral polymicrobial diseases.

Objective To analyze the value of MRI in the diagnosis of giant cell tumor of tendon sheath(GCTTS). MethodsThe MR images of 21 GCTTS cases including 3 cases of recurrences were retrospectively evaluated.All were confirmed giant cell tumor of tendon sheath by surgery and pathology.All the patiens were examined by MRI,and 19 received contrast enhanced MRI.The characteristics of MRI presentations were explored.Results Of the 21 cases,17 were in diffuse form and 4 in localized form.On T1WI,the signal intensities of the giant cell tumor of tendon sheath almost equalled to those of skeletal muscle in 18 cases and were slightly lower than those of skeletal muscle in 3 cases.On T2WI,the signal intensities tended to range between those of skeletal muscle and fat in 7 cases,almost equalled to those of skeletal muscle in 12 cases,and were slightly lower than those of skeletal muscle in 2 cases.Of the 19 cases with gadolinium-enhanced images,17 showed inhomogeneous enhancement and 2 homogeneous enhancement,and all were observed with a fat suppression sequence on T1WI. Conclusion MRI is able to depict the characteristic internal signal of giant cell tumor of tendon sheath,which is a valuable for diagnosis,treatment and follow-up.
