OBJECTIVESTo investigate the clinical effect of sequential therapeutic intervention Yupei Qisun [compensating for weakness by invigorating Kidney (Shen) and Spleen (Pi) in advance] in Chinese medicine (CM) and hysteroscopic endometrial mechanical stimulation on the treatment of infertile patients with repeated implantation failure (RIF); and to study the differences in patients' endometrial thickness and type on the day of embryo transfer, serum hormone levels on embryo transfer day and clinical pregnancy outcomes.

METHODSIn the clinical study, 168 frozen-thawed embryo transfer (FET) cycles for couples with RIF conforming to the research protocol were randomly divided into three groups: a CM group with 56 cycles (CM combined with FET), a hysteroscopy group with 55 cycles (hysteroscopic endometrial mechanical stimulation), and a control group with 57 cycles (conventional FET). Differences in endometrial thickness on the embryo transfer day, levels of serum estradiol (E2) and progesterone (P) on the embryo transfer day, the E2/P ratio on the embryo transfer day, biochemical and clinical pregnancy rates, implantation rate, abnormal pregnancy rate and other indices were compared among the three groups.

RESULTSEndometrial thickness, E2 and P levels, and the E2/P ratio on embryo transfer day and other factors had no significant differences among groups. The biochemical pregnancy, clinical pregnancy, and implantation rates of the CM and hysteroscopy groups were significantly higher than the control group (P<0.05), and there were no significant differences between these two groups. The abnormal pregnancy rate had no significant difference among the three groups.

CONCLUSIONSSequential therapy of Yupei Qisun could significantly improve the clinical outcomes of rif-fet cycles, being equivalent to hysteroscopic endometrial mechanical stimulation, and provided a reliable method to treat such infertile couples.

Objective To explore the effect of limited posterior fossa decompression(LPFD)in the treatment of Amold-chiari I malformation.Methods A retrospective analysis was conducted among 29 patients undergoing LPFD from 2004 to 2008.The standard surgical procedures included small osseous decompression of the occipital bone above the forarnen magnum,removal of the posterior arch of the atlas,separation of the arachnoid adhesions,and reduction of the inferior cerebellar tonsils,a dural graft for duraplasty.The outcomes of the surgeries were evaluated using the Tator criteria.Results Excellent results were obtained in 23(79.3%)patients according to the Tator scores,and good results were achieved in 6(20.7%)patients.During the follow-up of 15 patients,the syrmgomyelia was found to be further reduced in 9 patients,and 1 patient experienced recurrence.Conclusion Limited posterior fossa decompression is effective for management of Amold-chiari I malformation with minimal invasiveness and complications.

Objective To summarize the clinical characteristics of adolescents with symptomatic Chiari malformation type Ⅰ,and evaluate the clinical results of small-range posterior fossa decompression on these patients.Methods Twelve adolescents with symptomatic Chiari malformation type Ⅰ,admitted to and underwent a standard small-range posterior decompression surgery in our hospital from December 2006 to December 2011,were chosen; their clinical data were retrospectively analyzed.The standard surgical technique was composed of limited bone cut in 2 cm×2 cm,weak current coagulation in shrinking the tonsils,probe of aqueduct cerebrospinal fluid outflow tract and Magendie's foramen of the fourth ventricle,and suture of the dural grafting with patch ofautologous fascia.Preoperative and postoperative symptoms and sizes of syringomyelia were compared.Results Short-term follow-up showed that the clinical symptoms of patients improved significantly,and MRI confirmed that the syringomyelia disappeared or shrank in all the patients and the shape of cisterna magna recovered.Eight patients accepted follow-up for more than six months,showing continues improvement of clinical symptoms.Conclusion Small-range posterior fossa decompression surgery is important means to alleviate adolescent symptomatic Chiari malformation type Ⅰ.

OBJECTIVETo investigate the therapeutic efficacy and safety of salbutamol and dexamethasone added into large-volume whole lung lavage (WLL) fluid in patients with pneumoconiosis.

METHODSA total of 176 patients with pneumoconiosis were randomly divided into control group (n=86) and treatment group (n=90). The control group received WLL with 0.9% sodium chloride solution, while for the treatment group, salbutamol and dexamethasone were added into the WLL fluid for both lungs at the 1st and 4th WLLs.Before and after WLL, the pulmonary wheezing, arterial partial pressure of oxygen (Pa02), peak airway pressure(Pa peak), amount of intrapulmonary residual fluid, forced expiratory volume in one second (FEVw) (72 h later),diffusion capacity for carbon monoxide (DLCO ), and forced vital capacity (FVC) were measured for comparison between the two groups.

RESULTSAfter WLL, the treatment group had a significantly lower detection rate of pulmonary wheezing than the control group ( 13.3% vs 29.1 %, x2=5.028, ?=0.025), and the control group had a significantly higher incidence rate of pulmonary wheezing than the treatment group (21.8% vs 3.7%, 0R=5.423,95%CI 2.036-9.568 ). Compared with the control group, the treatment group had significantly higher Pa02 and significantly lower Pa peak and amount of intrapulmonary residual fluid (t =2.163 -4.132, P<0.05) and significantly higher FEV1, DLCO, and FVC (t=1.986-2.345, P<0.05) after WLL.

CONCLUSIONSalbutamol and dexamethasone added into large-volume WLL fluid may effectively alleviate bronchial spasm, reduce hypoxemia, and decrease Pa peak in patients with pneumoconiosis, thus promoting lung function recovery after WLL.

OBJECTIVETo evaluate the effects on cardiac remodeling post transcatheter closure by Amplatzer septal occluder selected by oval circumference formula in patients with atrial septal defect (ASD).

METHODSA total of 146 patients with ASD (68 males,mean 33.5 years) treated by transcatheter closure with the Amplatzer occluder were enrolled in this study. The diameter of defects was corrected with the oval circumference formula (group A, 73 cases) or by echocardiography (group B, 73 cases). Cardiac remodeling was assessed by transthoracic echocardiography (TTE) before the procedure, 3 days, 3 months and 6 months after ASD closure.

RESULTSThe mean ASD diameter was similar between the two groups [(20.16 +/- 4.98) mm vs. (21.36 +/- 5.69) mm, P > 0.05] and the mean diameter of the selected occluder of group A was significantly smaller than that in group B [(21.95 +/- 6.78) mm vs. (25.85 +/- 6.75) mm, P < 0.05]. Procedural success rate was identical between the two groups (97.3%) and the defects were completely occluded and there was no residual shunt during the 6 months follow up period, there were also no complications during and after the procedure. The lateral diameter of right atrial (RALD), the diastolic diameter of right ventricle (RVDD), RALD/LALD, RVDD/LVDD and pulmonary diameter (PD) were significantly decreased while the lateral diameter of left atrial (LALD) and left ventricle (LVDD) were significantly increased post ASD closure in both groups. At 6 months follow up, RALD decreased by (18.63 +/- 10.59)% in group A versus (10.14 +/- 6.59)% in group B, LALD increased by (13.42 +/- 8.38)% in group A versus (9.28 +/- 4.95)% in group B and RALD/LALD ratio decreased by (26.35 +/- 11.24)% in group A versus (13.98 +/- 8.96)% in groups B (all P < 0.05).

CONCLUSIONASD occluder selection based on the oval circumferen ce formula is superior to that made by echocardiography in terms of more favorable cardiac remodeling post ASD closure.

Objective To explore the endoscopic characteristics of multidrug-resistant tuberculosis (MDR-TB) combined with tracheobronchial tuberculosis (TBTB). Methods 248 MDR-TB as study group, they hospitalized from October 1st 2008 to June 31st, 2016. 274 cases of non MDR-TB with bacteria positive as control group over 2015, all of them received bronchoscopy, sputum cultured and drug sensitivity tested of Isoniazid and Rifampicin. We analyzed the results of bronchoscopy and demographic data. Results 248 cases of MDR-TB patients, of 175 (70.56%) were diagnosed TBTB by bronchoscopy, of 73 (29.44%) without TBTB. 274 cases of non MDR-TB with bacteria positive patients, of 146 (53.28%) were diagnosed TBTB, of 128 (46.72%) non TBTB, the difference of comparisons was statistically significant (χ2 = 16.42, P = 0.000). MDR-TB combined with TBTB median age was 32 years, non MDR-TB combined with TBTB median age 42 years, the difference was statistically significant (U = 9932.00, P = 0.001). Among the MDR-TB patients, of 75 (42.86%) TBTB in the upper right bronchial, of71 (40.57%) upper left bronchus, while non MDR-TB patients, of 70 (47.95%) and 60 (41.10%), there was no statistically significant difference (χ2 = 2.44, P = 0.786). Among the MDR-TB, of 76 (43.43%) were inflammation infiltration type, of 11 (6.29%) were necrosis type, of 13 cases (7.43%) granulation proliferative type, of 72 (41.14%) were scar stricture type, of 3 (1.71%) tube wall softening type. Among the non MDR-TB, in turn, TBTB type were 50 (34.25%), 41 (28.08%), 9 (6.16%), 40 (27.40%), 5 (3.43%), the difference were statistically significant (χ2 = 30.50, P = 0.000). Conclusions The detection rate of TBTB was higher in MDR-TB patients, that common occur in younger patients. TBTB common infringe on upper right bronchial and upper left bronchus, TBTB type most are inflammatory infiltration type and scar stricture type. More attention should be paid to bronchoscopy among MDR-TB patients.

The anhydrite and gypsum are the main sulfate minerals during evaporation of seawater or lake.They record the information about relative hydrogeology and the composition of mother liquor.Boron is diffluent element, and often occurs in all kinds of evaporites.Presently, the boron isotope has been applied widely in mineral deposits forming, geochemistry and palaeoenvironment.However, there is little research about characteristic of boron isotope in anhydrite and gypsum minerals, because of the low content of boron and micro-solubility in water and hydrochloric acid.This study developed a method of extracting and purifying boron in anhydrite and gypsum by phase transformation and ion-exchange.Firstly, the samples were mixed with ammonium hydrogen carbonate to transform the calcium sulfate to calcium carbonate.And diluted hydrochloric acid (1 mol/L) was added to resolve calcium carbonate.The percent conversion was about 85%in the first stage, and up to complete resolution by repeating this process.Secondly, boron specific ion-exchange resin ( Amberlite IRA 743 ) was used to gather the boron ions fully and further refined the samples with more than 1 μg of boron by anionic and cationic resin mixed by Ion Exchange Ⅱ and Dowex 50 W × 8.Finally, according to the modified method by He, the values of boron isotope were determined by TIMS.The boron content is analytically pure gypsum was 3.501 ± 0.128 μg/g ( n=12 , RSD=3.6%) and the average recovery was 100.47%.Besides, the δ11B value of analytically pure gypsum added with NIST SRM 951 was 17.98‰±0.21‰ (n=3, RSD=1.2%).This method has good repeatability and can meet the requirements of boron isotopic measurement of anhydrite and gypsum.

Objective: To observe influences of Chaihu-Longgu-Muli decoction (CLMD) on electroencephalogram (EEG), serum nerve growth factor (NGF) and brain derived neurotrophie factor (BDNF) level of patients with temporal lobe epilepsy. Methods: Single blind randomized controlled trial design was used. 138 patients with temporal lobe epilepsy were divided into oxcarbazepine group (including 67 patients), oxcarbazepine+ CLMD group (including 71 patients). After 28 d of treatment, EEG changes, NGF and BDNF changes in serum, and relevant serological indicator inspection of drug reactions in both groups were observed. Results: The effective rate of EEG in oxcarbazepine+ CLMD group was 81.8%, which was obviously higher than the oxcarbazepine group (50.7%), with significant difference (P<0.01). After treatment, NGF and BDNF of both groups were higher than those before treatment (P<0.05). Moreover, serum NGF and BDNF of oxcarbazepine+ CLMD group were higher than the oxcarbazepine group (P<0.05). There was no statistical significance in serological indicator of drug reactions in both groups (P>0.05). Conclusions The curative effects of oxcarbazepine+ CLMD is superior to the individual oxcarbazepine and it can obviously enhance serum NGF and BDNF of patients with temporal lobe epilepsy and reduce the status epilepticus of patients with temporal lobe epilepsy and it has the high safety.

Objective To analyze the temporospatial characteristics of traumatic brain injury (TBI) caused by Wenchuan earthquake, the distribution of the complex injuries, and the surgical timing and approaches. Methods The clinical data were retrospectively analyzed among 92 patients sustaining TBI in Wenchuan earthquake admitted in our department within 20 days after the injury. Results All the 92 patients came from the northwest Chengdu Champaign. Seventy-six patients were admitted within the initial 12 hours after earthquake, and 10 patients underwent surgical procedures. Forty-seven patients were cured, 31 were transferred to other provinces for further medical care, and 3 died. Conclusions Early TBI accounted for a large proportion of the TBI cases in Wenchuan earthquake, characterized by rapid progression of the condition. Early emergency surgeries can significantly improve the success rate of operations and lower the mortality rate.
