OBJECTIVE To study the clinical application and its advantage of cervical tongue-shaped flap in tracheal stoma after total laryngectomy.METHODS A tongue-shaped flap was retained underneath the U-shape incision in front of the neck.When tracheal stoma was made,the tongue-shaped flap was sutured with the mucous membrane of tracheal posterior wall.A little bit tissue of tracheal anterior wall in the broken end could be cut off and sutured with the skin under the tracheal stoma.RESULTS The diameter of the tracheal stoma was or not less than 3.0 cm?2.5 cm after operation.All the cases were followed up for 1 to 4.5 years after surgery.The tracheal stoma of all the cases grown downwards to 2.0～1.8 cm after a half to one year and then maintained invariably.The tongue-shaped flap and the skin around the tracheal stoma maintained smooth.It was not necessary for the patients to wear the trachea cannulas.CONCLUSION This method has lots of advantages such as less pain,lower medical cost and the increased recovery rate.

Objective To investigate curative effects and prognostic factors of video-assisted thoracoscopic extended thymectomy ( VATET ) for nonthymomatous myasthenia gravis ( NTMG ) . Methods Clinical records of 43 patients with an established diagnosis of NTMG who underwent VATET from December 2009 to September 2014 were reviewed. Three-port thoracoscopic right thymectomy with resection of fat tissue in anterior mediastinum was conducted.The curative effects and prognostic factors were evaluated and analyzed with the Monden standard. Results The VATET was successfully completed in all the 43 patients.The operation time was 75-240 min (mean, 115.4 min).The intraoperative blood loss was 10-200 ml (mean, 42.2 ml). No peri-operative death occurred.Follow-ups for 4 -60 months ( mean, 36.2 months) showed 12 cases of remission, 18 cases of improvement, 10 cases of unchanged disease, and 3 cases of deterioration.The effective rate was 69.8% (30/43).Multivariate logistic regression analysis showed that pathological type of thymic hyperplasia was the independent risk factor for NTMG postoperative outcomes (β=0.921,95%CI:1.866-2.811, P=0.000). Conclusion Video-assisted thoracoscopic extended thymectomy is effective in most myasthenia gravis patients.

Objective To investigate the clinical efficacy of acupoint PLGA thread embedding in treating simple obesity. Methods Ninety-six patients with simple obesity were randomly allocated to treatment and control groups, 48 cases each. The treatment group received acupoint PLGA thread embedding and the control group took metformin hydrochloride tablets. Body weight, waist circumference, abdominal circumference and related laboratory indices were measured in the two groups before treatment and at the end of treatment and the one-year follow-up. The clinical therapeutic effects were compared between the two groups.Results The total efficacy rate was 90.9% at the end of treatment and 77.3% at the one-year follow-up in the treatment group and 97.5% at the end of treatment and 37.5 at the one-year follow-up in the control group. There was a statistically significant difference in the total efficacy rate at the one-year follow-up between the two groups (P<0.01). There was a statistically significant post-treatment difference in TG between the treatment and control groups (P<0.05). There were statistically significant differences in waist circumference, hip circumference, obesity degree, TG and LP at the one-year follow-up between the treatment and control groups (P<0.05). There was a statistically significant difference in the incidence of adverse reactions at the one-year follow-up between the two groups (P<0.01). Conclusion Acupoint PLGA thread embedding is an effective way to treat simple obesity.

Objective To explore the indoor air pollution and its health effects in newly decorated rooms. Methods Indoor air sampling was conducted in rooms of 13 newly decorated apartments during the period from the 1st day to the 4th day, the 2nd month and the 6th month after the decoration. The levels of formaldehyde, benzene, o-dimthylbenzene, m-dimethylbenzene, para-dimethylbenzene in air samples were analyzed. An epidemiological investigation on the adverse response of eye and respiratory system was carried out among the family members before and after decoration. Results The levels of formaldehyde, benzene and dimethylbenzene in indoor air exceeded ther related standards more than 2.92 times, 7.4-11.3 times, 58.2-87.1 times respectively, and showed a decreasing trend with the prolongation of time after decoration. The positive rates of shedding tears and sneezing, branchitis or cough, asthma, dizziness among family members were 0%, 3.0%, 3.0%, 0% respectirely before decoration and rose to 24.2%, 7.6%, 6.1%, 7.6% respectively after decoration. Conclusion The indoor decoration resulted in the indoor air pollution by formaldehyde and benzene compounds, the contamination degree showed a positive correlation with the degree of complicated decoration and was associated with the quality of decorative materials. Indoor decoration also resulted in the increasing positive rates of adverse response of eye and respiratory system.

Although breast feeding has long been proved to be the best way tor infant feeding, for many reasons, however, the number of breast-fed infants were always fewer than those of artiticially or mixed fed ones either in urban or in rural, e.g. it was found that only 35.7% of infants aged 4 months in Shanghai were breast-fed in 1980. Therefore manufacturing some kinds of humanized milk for improving infant nutrition seems necessary.A humanized milk powder was manufactured in Hongyuan Powdered Milk Factory. For testing its suitability for infant nutrition, a feeding experiment in infants was conducted in our laboratory in spring 1982.75 healthy babies aged 1-5 months were equally randomly assigned into three groups, i. e. humanized milk group, breast feeding group, and cow's milk group. The other food supplements except the milks were same in all groups.All the babies were subjected to anthropometric examination and blood hemoglobin determination before and after the 3 months' experimental period.Experimental results showed that there was no significant difference between the three groups either in growth and development or in blood hemoglobin level.In addition, Hongyuan humanized milk powder was also found to be more digestible and acceptable for the majority of the tested infants.

Objective To compare the efficacy of uniportal VATS and single utility port VATS in treatment of spontaneous pneumothorax.Method From January 2013 to December 2015, we retrospectively collected clinical data of 53 patients with spontaneous pneumothorax who were treated with uniportal VATS, as study group; compared with control group: 53 patients received single utility port VATS in the same period. The clinical data was compared between the two groups, including the operation time, intraoperative blood loss, drainage time, postoperative extubation time, postoperative pain score, postoperative hospitalization and recurrence.Results All patients were successfully completed the operation, no death and serious complications occurred. There were no significant differences in intraoperative blood lose, duration of chest drainage, duration of hospital stay and incidence of serious postoperative complications between two groups (P > 0.05). Mean Visual Analogic Scale (VAS) score for 24 h post-operative pain was: (2.60 ± 0.71) for uniportal VATS and (3.38 ± 0.84) for single utility port VATS (P > 0.05), 72 h post-operative pain was: (1.30 ± 0.51) for uniportal VATS and (1.58 ± 0.62) for single utility port VATS (P > 0.05). Follow up 5 ~ 36 months, median follow up was 19 months. No recurrence occurred during follow up.Conclusions The study suggested that both surgical approaches to spontaneous pneumothorax are safe and effective. Significant differences were found for early post-operative pain between the two approaches, the uniportal way is better. It is worthy of clinical promoting.

Background Ex-PRESS glaucoma drainage device implantations have been clinically applied worldwide.In China,50 type and 200 type of Ex-PRESS glaucoma drainage devices are used for different types of open angle glaucoma.However,whether the clinical outcomes are similar between 50 type and 200 type of Ex-PRESS glaucoma drainage devices are not elucidated.Objective This study was to compare the therapeutic efficacy and security of Ex-PRESS implantation between PS0 type and P200 type of Ex-PRESS glaucoma drainage devices for open angle glaucoma Methods A randomized,parallel-group trial was designed,and written informed consent was obtained from each patient prior to entering in the cohort.Eighty eyes of 69 patients with various types of open angle glaucoma were included from March 2012 to April 2013 in Wuhan General Hospital of Guangzhou Military Command.The patients were randomized into 2 groups according to randomized digital table.The P50 type Ex-PRESS glaucoma drainage device was implanted in 40 eyes of 35 patients in the P50 group,and P200 type was implanted in 40 eyes of 34 patients in the patients of the P200 group.The disease composition,best corrected visual acuity (BCVA) recovery time,theoretical hospitalization days,lowing intraocular pressure (IOP) range and postoperative complications were compared between the two groups.Results The average lowing-IOP ranges of the P50 type group and P200 type group were (21.19±11.22) and (24.35±12.27) mmHg,respectively,with an insignificant difference between them (t =-1.201,P＞0.05).The theoretical hospitalization days and BCVA recovery time in the of P50 type group were (3.65±0.92) days and (2.85±0.95)days,and those in the P200 type group were (4.90±0.81) days and (3.40± 0.96) days,showing significant decreases in the P50 type group (t =-6.444,P＜0.01 ;t =-2.584,P＜ 0.05).The incidence of postoperative complications were 6.06％ and 25.00％ in P50 type group and P200 type group,respectively,with a significant difference between the two groups (.x2 =9.800,P＜0.05).Conclusions Although P50 and P200 Ex-PRESS implantation provide a similar effect in lowing IOP,P50 type Ex-PRESS implantation can restore BCVA more rapidly and lessen complications in comparison with P200 type Ex-PRESS implantation in the early postoperative stage.
