The fluid-bed spray dryer was developed for PVA-film coating of the granules made of extract from Chinese traditional medicine. The experiment result indicated that the dissolution rate of granules from Dengzhanxixin Capsules wash't affected by PVA-film coating. The coated granules could be filled into capsules easily. Their stability was highly raised. This new technology basicalcy solved such problems as: easy moisture-absorbing of extract after vacuum drying at low temperature, difficult capsule-filling and poor stability, which led to the assurance and lift of preparation quality.

Objective To study the different effects of early active mobilization on flexor ten don sheath regeneration when the sheath has bee n partially removed and when the inju red sheath has been sutured.Methods In 192Leghorns involved in this study,the zone II flexor digital profoun d tendons were partially ruptured at their bilateral 3rd digits.Their te ndon sheathes were partially removed or sutured.All the Leghorns were di vided into four groups randomly:active mo bilization-sheath removed(A 1 ),active mobilization-sheath sutur ed(A 2 ),immobilization-sheath removed(C 1 ),and immobilization-sheath suture d(C 2 ).Their toes were harvested in the1st,2nd,3rd,4th,8th and 12thweeks postoperatively.Then morphologic al observations and biomechanical tests were performed.All data were s tatistically analyzed.Results In the 1st week postoperatively,the tendon sheath structure disappeared in the injured areas in both groups of A 2 and C 2 ,while in groups of A 1 and A 2 ,neogenetic tendon sheath formed in t he operation areas.In groups of C 1 and C 2 dense scar tissues developed around the tendon without neogenesis of tendon sheath or sheath-like str ucture.There was no significant dif ference either morphologically or biomechanically between A 1 and A 2 as well as C 1 and C 2 while significant differences were found between A 1 and C 1 as well as A 2 and C 2 .Conclusions The pathologic transformation afte r sheath repair during active mobilization c an be divided into three stages:The s heath decomposed and degenerated in the1st week postoperatively.Early neogenetic sheath formed in 2weeks.The neogenetic sheath matured in 4to 8weeks.Active mobilization to promo te neogenesis of sheath is a key facto r to prevent adhesion.Only tendon sheath repair cannot prevent adhesion effectively.

Objective To evaluate the effects on mechanical ventilation in ICU patients with dexmedetomidine merely and combined with dezocine, fentanyl, respectively.Methods Fifty-seven patients with mechanical ventilation in ICU were collected during Jun till Dec in 2016, 35 males and 22 females, aged 18-75 years, and classified into three groups with random number table method, among whom there were 17 patients treated with dexmedetomidine, 20 patients treated with dexmedetomidine combined with dezocine and 20 with dexmedetomidine plus fentanyl, the general condition, pain score, MAP and HR were compared before and after the treatment, ideal treatment time and mechanical ventilation time were also compared among the different groups.Results There were no statistical differences in the general condition, CPOT score, MAP and HR at different points and mechanical ventilation time.Whereas, the time of ideal sedation and analgesia was significantly faster in group C than that of groups A and B (P<0.05).Conclusion Dexmedetomidine combined with dezocine can reach the ideal analgesic effect more rapidly than dexmedetomidine solely or combined with fentanyl.

OBJECTIVETo investigate the reconstruction of 1/4 defect on upper-lip vermilion with a lower-lip vermilion compound tissue flap pedicled at oral commissure.

METHORDSAt the first stage, the lower lip mucosal flap pedicled by inferior labial artery was transposed to reconstruct the defect on upper lip vermilion and tubercle. The defect at the donor site was closed directly. At the second stage, the flap pedicle was cut off and revised.

RESULTS6 patients were treated with satisfactory aesthetic results. All the flaps survived completely. The oral commissure kept normal with no obvious scar at the donor sites.

CONCLUSIONSThe modified crosslip vermilion flap pedicled at oral commissure has the advantages of avoiding inconvenience in feeding, speaking and cleaning. The procedure is simple with available blood supply. Both aesthetic and functional results are satisfactory.

Mitochondria play a central role in the regulation of cellular energy metabolism, bio-synthesis and cell death. Dysfunction of mitochondria can lead to many diseases. Mitochondrial proteomics provides important theoretical foundation for a systematic understanding of the biological functions of mitochondria, studying the mechanisms of mitochondria-related diseases, and promoting the research and development of mitochondria-targeting drugs. The methodologies, recent technology development, and characteristics and applications of mitochondrial proteomics were reviewed and the challenges and prospects were also discussed.

Objective To observe the mRNA expression levels of POT1 in peripheral blood mononuclear cells of acquired aplastic anemia patients with different syndrome, and explore its relationship with acquired aplastic anemia and its TCM syndrome. Methods Peripheral blood mononuclear cells of 52 cases with acquired aplastic anemia and 20 cases as control group were collected to detect mRNA expression of POT1 by using real-time quantitative polymerase chain reaction (RT-qPCR), and its relation with TCM syndrome was analyzed. Results The expression levels of POT1 mRNA in patients with acquired aplastic anemia were lower significantly than control group (P<0.05). The expression levels of POT1 mRNA in patients with deficiency of kidney-yin were lower than patients with deficiency of kidney-yang, and it was lowest in patients with kidney deficiency of both yin and yang. There was significant correlation between the expression levels of POT1 mRNA and age (r=0.374, P=0.038). Conclusion The changes in expression levels of POT1 play a role in the pathogenesis of acquired aplastic anemia. There is correlation between mRNA expression level of POT1 in peripheral blood mononuclear cells and TCM syndrome.

AIM To compare the effects of probimane( Pro), bimolane ( Bim) and razoxane( Raz) on animal tumor metastasis in vivo . METHODS A biological inoculation method for assessment of pulmonary metastasis of Lewis lung carcinoma(3LL) was employed. RESULTS Pro and Bim inhibited the pulmonary metastasis of 3LL both from d 2 and from d 8 injections, but Raz only inhibited the pulmonary metastasis of 3LL from d 2 injections. Pro inhibited the pulmonary metastasis of 3LL more potently than Bim did at equitoxic dosage. CONCLUSION Pro is better in the treatment of pulmonary metastasis of 3LL than Raz for its possible novel molecular mechanisms.

Objective To investigate the change and clinical significance of thyroid CT value in patients with Graves disease and Hashimoto' s thyroiditis (HT).Methods One hundred and twelve Graves patients (GD group),54 HT patients (HT group) and 36 healthy people (NC group) were selected as our subjects.Computed tomography (CT) value of thyroid were measured.Results The CT value of the left thyroid gland was (70.53 ± 15.44) Hu in GD group,while (70.50 ± 16.01) Hu at the right side.In HT group,the CT value of the left thyroid gland was (53.77 ± 4.88) Hu,and (52.38 ± 6.67) Hu at the right side.The CT value of the left and right sides was (99.66 ±9.80) Hu and (100.77 ± 10.66) Hu in the NC group respectively.The CT value of GD and HT group were lower than that of the NC group (P ＜ 0.01),and the CT value of the HT group lower than that of the GD group more significant (P ＜ 0.01).Conclusion (1) The CT value of the GD group and the HT group are significantly lower than the NC group and the CT value of the HT group reduces more apparently than that of the GD group.(2) CT values can be used as an early,non-invasive diagnosis of GD and HT secondary indexes.

Objective To investigate prevalence and risk factors of pelvic organ prolapse in women underwent routine gynecologic health care in Peking Union Medical College Hospital (PUMCH).Methods From Jan.2008 to Aug.2009,972 women underwent gynecological health care in PUMCH Were enrolled in this study.Questionnaires and pelfic examinations were given.The pelvic organ prolapse quantitive examination(POP-Q)system was used as the assessment tool.Results (1)Among all participants,the mean ages were(42±10)years(range 22 to 78 years),the mean height were(162±5)cm(range 142 to 180 cm),and the mean weight were(59±8)kg(range 42 to 91 kg).83.8%(815/972)of women were multipara.The mean total vagihal length(TVL)of 972 women was 8.20 cm.No women met the standard of pelvic organ prolapse, while 35.5% (345/972) of women presented mild posterior vaginal descent and 96. 7% (940/972) presented mild anterior vaginal descent, all of them were asymptomatic. (2) The length of genital hiatus (gh), TVL and C, D proximal to the hymen in nullipara were (2.26 ±0. 32), (8.08 ±0. 30), ( - 7.08 ± 0. 24) and ( - 8. 08 ± 0. 30) cm, which were significantly less than ( 2. 33 ± 0. 39 ),( 8. 22 ± 0. 35 ), ( - 7. 14 ± 0. 28 ) and ( - 8. 22 ± 0. 35 ) cm in multipara ( P < 0. 05 ). Ap and Pb proximal to the hymen of ( - 2. 87 ± 0. 22) and ( - 2. 87 ± 0. 22 ) cm in nullipara were significantly larger than ( -2.81 ±0.25) and ( -2.81 ±0.25) cm in multipara (P<0.05). When compared with nullipara, the incidence of posterior and anterior vaginal wall protrusion were increased ( OR = 1. 819). (3) The index of POP-P were compared among women at groups of 22 -34 years, 35 -49 years and more than 50 years (P <0. 05 ). Those index did not show statistical difference between women at group of 22 - 34 years and group of 35 -49 years (P >0. 05). However, those in women at group of 22 -34 years and 35 -49 years showed statistical difference when compared with women at group of more than 50 years ( P < 0. 05 ). When compared with women at group of 22 - 34 years, the incidence of posterior and anterior vaginal wall protrusion were increased ( OR = 1. 713, 3. 765). (4) Menopause status was associated with severities of all kinds of descent ( P < 0. 05 ) and presence of posterior vaginal protrusion ( OR = 3. 354 ). Conclusions Mild anterior and posterior vaginal descent by POP-Q were common among women in China. The risk of anterior vaginal descent is relatively higher than posterior vaginal descent. However, most of the women with descent are asymptomatic and need no treatment. The most important factors associated with the severity and detectable ratio of descent is parity and age.
