Objective To investigate the effects of acupuncture rehabilitation techniques combined with Xingnaojing injection on functional recovery and the plasam level of glial fibrillary acidic protein (GFAP) in patients with severe traumatic brain injury (STBI).Methods Eighty-four patients with STBI admitted to Department of Neurosurgery in Jiuquan People's Hospital from October 2013 to December 2015 were enrolled,they were divided into observation group (44 cases) and control group (40 cases) by random number table,all patients received the routine basic treatment,such as decreasing intracranial pressure,anti-infection,neural nutrition therapy,etc.In addition,the observation group was treated with acupuncture rehabilitation training (each training 50 minutes,1-2 times a day,10 times as a course of treatment,a total of 5 courses) and Xingnaojing injection (in 0.9％ normal saline or 5％ glucose injection 250 mL intravenous infusion,one time a day,10 days as a course of treatment,a total of 3 courses).The evaluation score of Montreal cognitive assessment (MoCA),Modified Barthel index (MBI),Fugl-Meyer assessment (FMA) of motor function score and the plasma levels of GFAP and myelin basic protein (MBP) were measured before and after treatment in the two groups.Results After treatment,the MoCA,MBI and FMA scores were significantly higher in two groups than those before treatment (all P ＜ 0.05),the contents of MBP and GFAP were significantly lower than those before treatment,and the changes in observation group were more significant than those in control group [visual space and execution capability (score):4.99 ± 0.67 vs.3.42 ± 0.73,denomination capability (score):2.98 ± 0.77 vs.2.84 ± 0.47,delayed memory (score):5.76± 0.33 vs.3.87± 2.08,attention (score):6.17± 0.65 vs.4.75 ± 0.81,speech capability (score):3.51 ± 0.46 vs.2.04 ± 0.13,abstract thinking capability (score):2.94 ± 0.27 vs.1.58 ± 0.96,orientation force (score):6.02±0.65 vs.4.88±0.62,FMA score:68.71 ±34.17 vs.41.13 ± 14.82,MBI score:69.12± 10.45vs.37.63±6.11,MBP (μg/L):1.32±0.23 vs.5.31±0.79,GFAP (μg/L):0.19±0.08 vs.0.39±0.04,all P ＜0.05].Conclusions Acupuncture rehabilitation training combined with Xingnaojing injection may obviously improve the cognitive and motor functions in patients suffered from STBI,and clinically the combined treatment is worthwhile to be used extensively.

Objective To investigate the recurrence and risk factors of gastric high-grade intraepithelial neoplasia(HGIN)and early gastric cancer(EGC)after endoscopic submucosal dissection (ESD). Methods The clinical and follow-up data on 444 patients(451 lesion)with HGIN and EGC undergoing ESD in Digestive Endoscopy Center of Chinese PLA General Hospital from November 2006 to January 2016 were summarized, and the risk factors of recurrence were analyzed. Results A total of 410 patients were followed-up, and the recurrence rate was 3.2%(13 patients, 13 lesions), with mean recurrence time of 17.6±9.6 months(6-38 months). Univariate and multivariate analysis revealed that the size of the lesion>4.0 cm was the only risk factor of recurrence(P=0.012,OR=10.855,95%CI:1.673~70.442). Conclusion The rate of recurrence is increasing with the EGC extending, therefore, postoperative monitoring should be strengthened to patients with larger lesion.

OBJECTIVETo investigate the quality of life ( QOL) of inpatients with coal workers' pneumoconiosis( CWP) and analyse its influential factors, and to provide a theoretical basis for effective control measures.

METHODSEighty-eight CWP patients in a hospital were included in the study. A questionnaire survey was conducted in them using a self-designed QOL scale. A database was established by software EpiData3.1, and the obtained data were statistically analyzed by software SPSS 16.0.

RESULTSOf the 88 patients, 73( 82.9%) had middle-level QOL, with a mean QOL loss rate of 36.2%; the loss rates of physical function and somatic sensation were the highest ( 44.2% and 41.5%). The patients with stage II CWP had significantly lower physical function than those with stage I and III CWP; the physical function and social function of patients significantly decreased with age; the personal income, household income, and housing condition of the patients had a marked impact on their physical and psychological functions, and the housing condition and education level had a marked impact on their social function. The multivariate analysis showed that old age, low income,and poor housing condition were the main adverse factors for the QOL of inpatients with CWP.

CONCLUSIONThe QOL of inpatients with CWP declines significantly, and their QOL is related to the age, income, and satisfaction with housing condition.

Asthma is an increasingly prevalent, often severe disease and the common cause of significant respiratory morbidity in the developed world. Mast cells play an important role in allergy diseases, but the role of epithelial mast cells in the asthma remains controversial. In this research, we assessed the number of the mast cells in the lungs of the ovalbumin (OVA)-induced murine asthma model. BALB/C mice, 6-week age, were intraperitoneally injected with 10% OVA 200 microliter with aluminum hydroxide on days 0 and 10 and challenged via the airways with 1% OVA for 20 min on days 17, 24, 31, 38, 45 by intra-tracheal inhalation, and assessed after 7 days of last challenges, respectively. The control group was assessed with sensitization only. The lungs were stained with hematoxylin-eosin, Congo red, toluidine blue, and periodic acid Schiff-hematoxylin, respectively. The mast cells were observed by light microscope and analyzed with image analysis system. There were no intraepithelial mast cells in the lungs of the normal and control mice. The number of intraepithelial mast cells increased in proportion to OVA challenge times in the epithelium of lungs. This result shows that the intraepithelial mast cells of lungs in the OVA-induced asthma model increased along with the challenge times. So the intraepithelial mast cells may play an impotent role in the OVA-induced asthma model.

OBJECTIVETo observe the effect of different concentration of Tamoxifen ointment on the fibroblasts and transforming growth factor (TGF-beta2) of hypertrophic scar at rabbit ears, so as to explore the possibility of treatment of hypertrophic scar with Tamoxifen.

METHODSThe hypertrophic scar model was established in 96 New Zealand rabbits' ears. The wounds were divided into four groups (A, B, C and D), with 144 wounds in each group. Different concentration of tamoxifen ointment (0.5%, 1%, 2%) was topically administered in groups A, B and C respectively, and blank ointment in group D. On postoperative day 30, 60 and 90, the scar samples were harvested. The scar thickness, scar histological change and the content of TGF-beta2 were detected.

RESULTS(1) On the 30th day after operation, the difference of scar tissue thickness among groups A, D and B, C reached statistical significance (group A, D < group B < group C). However, there was a contrary tendency in fibroblasts density and TGF-beta2 content of the scar tissue simultaneously. (2) On 60th, 90th day after injury, there was statistical difference in scar thickness, fibroblasts density and the content of TGF-beta2 in scar of four groups (P < 0.05). The content of TGF-beta2 in group A, B, C, D was (43.97 +/- 3.63) microg/L, (41.92 +/- 3.91) microg/L, (36.69 +/- 4.15) microg/L, (54.90 +/- 4.71) microg/L, respectively, on 60th day; and (45.69 +/- 2.63) microg/L, (40.43 +/- 3.87) microg/L, (38.76 +/- 3.24) microg/L, (52.59 +/- 4.92) microg/L, respectively, on 90th day. The fibroblasts density of scar in groups A, B, C, D was (4392.07 +/- 327.84) point/mm2, (4208.57 +/- 329.76) point/mm2 (4 033.44 +/- 427.91) point/mm2, (4863.03 +/- 387.98) point/mm2, respectively, on 60th day; and (4418.41 +/- 432.52) point/mm2, (4077.65 +/- 386.70) point/mm2, (3844.53 +/- 354.29) point/mm2, (4838.64 +/- 390.52) point/mm2, respectively, on 90th day. The content of TGF-beta2 and fibroblasts density of scar were lined up as group D > group A > group B > group C (P < 0.05).

CONCLUSIONSTopical Tamoxifen can reduce the content of TGF-beta2 and fibroblast, decrease fibroblasts density and the formation of hypertrophic scar at rabbit ears. It offers a new way for the treatment of the hypertrophic scar.

OBJECTIVETo explore an appropriate measure to repair tissue defects and deformities in mandibulo-cervical region.

METHODSEighteen cases with severe tissue defects and deformity in jaw and neck were repaired with thoracic skin flap with multiple blood supply system in our unit from Jan. 2006 to Nov. 2008. Anterior cutaneous branch of transverse cervical artery, intercostal branch of internal thoracic artery and lateral thoracic artery were included in the pedicles.

RESULTSAll skin flaps survived, except in one patient in whom a small belb appeared at the distal end of the island flap with anterior cutaneous branch of transverse cervical artery, and it was healed after a few dressing changes. The functions and appearances were satisfactory after 6-month to 2-year follow-up, without showing secondary deformity.

CONCLUSIONSThe blood supply of thoracic skin flap is abundant and constant, which is an ideal method for repair of tissue defects and deformities in jaw and neck after taking into account some factors, such as the demand of the patient, general physical condition, and the size of the defect.

OBJECTIVETo explore the mechanism of acupuncture on the treatment of glaucoma so as to find out a kind of simple and effect approach to control and stabilize intraocular pressure (IOP) of patients with glaucoma.

METHODSThirty-nine cases (75 eyes) of glaucoma (unstable control of IOP) were treated with acupuncture at Sibai (ST 2), Cuanzhu (BL 2), Jingming (BL 1), Qiuhou (EX-HN 7), etc. IOP before and after acupuncture, at 10 a.m, 2 p.m, 6 p.m, 10 p.m., at 5 a.m. and 7 a.m. on the second day as well as diurnal IOP variation in 24 h were observed separately.

RESULTSAfter acupuncture, IOP at each time point reduced as compared with that before acupuncture. IOP at 5 a.m., 7 a.m., 10 a.m., 6 p.m. and 10 p.m. after acupuncture was different significantly in statistics as compared with that before acupuncture correspondingly (all P<0.05). After acupuncture, 24 h diurnal IOP variation was (5.31 +/- 2.84) mmHg, which was lower significantly than (7.06 +/- 3.86) mmHg before acupuncture (P<0.05).

CONCLUSIONFor the patients with unstable control of IOP, acupuncture can not only reduce IOP, but also stabilize 24 h diurnal IOP variation and benefit the visual function of patients with glaucoma.
