ABSTRACT
Objective:To investigate the changes of sphenoid sinus and related risk factors of sphenoid sinusitis after microscopic transsphenoidal pituitary adenoma resection.Methods:The clinical and imaging data of 106 patients with large pituitary adenoma in 900 Hospital of the PLA Joint Logistics Team between August 2012 and March 2015 were continually collected. The changes of accumulated blood and fluid, inflammation, mucocele, mucosa remodeling in sphenoid sinus cavity at preoperative and postoperative different time points were observed through the analysis of magnetic resonance imaging (MRI). Binary logistic multiple factors regression model was used to analyze the independent risk factors for postoperative sphenoid sinusitis.Results:MRI results showed that the blood and fluid accumulated in sphenoid sinus cavity were absorbed and dissipated 3 months after the surgery, and the saddle bone windows were covered by new mucous membrane at this time, but they were not complete; the remaining tumors in the saddle all sank into the saddle to different degrees. The reconstruction of sphenoid sinus mucosa was basically complete 6 months after the surgery. There were 7 (6.6%) cases of mucocele in sphenoid sinus and 26 (24.5%) cases of sphenoid sinusitis 3 months after the surgery among 106 patients. The results of multivariate analysis showed that growth hormone adenoma ( OR = 2.981, 95% CI 1.480-26.207, P = 0.014), preoperative sphenoid sinusitis ( OR = 12.392, 95% CI 2.927-52.462, P = 0.001), frequency of multiple transsphenoidal surgery ( OR = 14.758, 95% CI 2.431-89.584, P = 0.003) and perioperative cerebrospinal fluid leakage ( OR = 11.644, 95% CI 2.175-62.344, P = 0.004) were independent risk factors for postoperative sphenoid sinusitis. Conclusions:The evolution of sphenoid sinus cavity contents has its own rules after microscopic transsphenoidal pituitary adenoma resection. Patients with growth-hormone pituitary adenoma, sinusitis before surgery, multiple transsphenoidal surgery and cerebrospinal fluid leakage during the surgery should receive enhanced anti-infection treatment and nasal care in perioperative period to reduce the possibility of sphenoid sinusitis after surgery. The staged time of reoperation for pituitary adenoma resection by transsphenoidal approach should be about 3 months after the previous operation.
ABSTRACT
@#Objective To observe the effect of repetitive focal muscle stimulation on recovery of upper limb function after stroke.Methods From October, 2016 to February, 2018, 46 stroke patients at early stage were recruited and divided into control group (n=23) and observation group (n=23). Both groups received basic rehabilitation training. The observation group accepted additional repetitive focal muscle stimulation on palms, forearm extensor carpi radialis, biceps brachii and muscles around scapula. The control group received sound stimulation as placebo treatment. The treatment was implemented once a day, five days a week for four weeks totally. The scores of Fugl-Meyer Assessment -Upper Extremities (FMA-UE), the Motricity Index of Upper Extremities (MI-UE) and the Hong Kong version of Functional Test for the Hemiplegic Upper Extremity (FTHUE-HK) were compared before and four weeks after treatment. Results After treatment, the scores of FMA-UE, MI-UE and FTHUE-HK improved in both groups (F>2.577, P<0.05), and were higher in the observation group than in the control group (t>2.153, P<0.05).Conclusion Repetitive focal muscle stimulation could facilitate to recover the function of upper limb in early-stage stroke patients.

Methods:Sixty-eight KOA patients were randomized into a treatment group and a control group, 34 in each group. The treatment group was intervened by warm needling, while the control group was by conventional acupuncture. The intervention started from the first day of the canicular days, once every day, 10 sessions as a treatment course. The improvement and therapeutic efficacy were evaluated after 3 courses of treatment. Results:The total effective rate was 91.2%in the treatment group versus 67.6%in the control group, and the difference was statistically significant (P Conclusion:Warm needling in canicular days can produce a better efficacy in treating KOA than conventional acupuncture.
ABSTRACT
Effective treatments of acute ischemic stroke include the specialist wards (stroke units) with multidisciplinary treatment team receiving treatment and intravenous thrombolytic therapy.However,only a few patients can receive these treatments.Telestroke can improve the thrombolytic rate of acute ischemic stroke on site in hospitals for lacking of specialists and enable stroke care maintained at a high level in rural areas.This article reviews telestroke in the treatment of acute ischemic stroke and the roles of nurses in telestroke.
ABSTRACT
Objective To compare the clinical efficacies of vasiculation moxibustion with pastes prepared in different ways and at different acupoint groups in treating allergic rhinitis due to deficient cold of lung qi. Method Eighty subjects were randomized into 4 groups, 20 in each group. Raw Bai Jie Zi (Semen Brassicae) was used in the vesiculation paste for group 1 and 2;stir-baked Bai Jie Zi (Semen Brassicae) was used for group 3 and 4. In group 1 and group 3, bilateral Feishu (BL 13), Fengmen (BL12), and Gaohuang (BL 43) were selected; in group 2 and group 4, bilateral Dazhu (BL11), Geshu (BL17), and Shenshu (BL23) were selected. The symptom and sign scores were compared before and after intervention. Result There were significant differences in comparing the symptoms and signs among the four groups (P＜0.05), and paired comparisons showed that the therapeutic efficacies of group 1 and group 3 were significantly higher than that of group 2 and group 4 (P＜0.05), while the differences in the therapeutic efficacy between group 1 and group 3, group 2 and group 4 were statistically insignificant (P>0.05). Conclusion Vesiculation moxibustion at the point group of Fengmen (BL12), Feishu (BL13), and Gaohuang (BL43) can markedly improve the symptoms and signs of allergic rhinitis due to deficient cold of lung qi;raw and stir-baked Bai Jie Zi (Semen Brassicae) can work equally in vesiculation paste for allergic rhinitis.

ABSTRACT
Objective:To analyse the causes of early implantation failure and the therapeutic measures with re-implantation after the failures.Methods:6 cases of implantation failure including early infections,loosening and non-osteointegration were reviewed and trea-ted by re-implantation therapy,and the causes of failure were discussed and the effects of re-treatment were evaluated.Results:2 cases were found to be with infection of adjacent teeth after implantation and were treated by removal of the implant,socket curettage,root ca-nal therapy(RCT)and antibiotics followed by reimplantation.Implant loosening and non-osteointegration were observed in 4 cases, which were treated by the similar methods for the implant socket.Reimplantation was successful in all 6 cases followed-up for 1 -3 years.Conclusion:Preventive measure for implantation failure should include indication selection,control of infections in adjacent teeth and periodontosis,use of GBR technic and so on.Re-implantation following proper treatment of adjacent teeth and the socket of implant is effective for the treatment of implantation failure.
ABSTRACT
This article was aimed to evaluate clinical efficacy of the pulmonary rehabilitation health education guidance mode. The CAT assessment tool was used for evaluation of stable chronic obstructive pulmonary disease (COPD) inpatients and outpatients in the Respiratory Department, Affiliated Hospital of Traditional Chinese Medicine of Xinjiang Medical University. A total of 80 stable COPD patients were randomized divided into the treatment group and control group. In the treatment group, stable COPD patients received pulmonary rehabilitation health education guidance. And then the quality of life was evaluated. The results showed that compared with the control group, after 48-week health education intervention, the CAT score and dyspnea index scale score of 40 patients in the treatment group were decreased with significant difference (P < 0.05). It was concluded that the guidance mode of pulmonary rehabilitation health education was conducive to improving the quality of life of pa-tients with COPD, decreasing the dyspnea index score, and improving exercise tolerance in patients to a certain extent. This pattern can be implemented in the optimization of future clinical practice and nursing.
ABSTRACT
Aim: To investigate a new type wound dressing,basic fibroblast growth factor(bFGF)/collagen com-posite sponge,and conduct its pharmacological studies in vitro and in vivo.Methods: bFGF/collagen composite sponge was prepared using fresh pig skin and bFGF.The sponge's physicochemical properties were studied.MTT assay was used to detect the proliferation effect of the sponge extract on 3T3 cells.Delayed allergy of the sponge was tested for the assurance of its biosafety.Results: Results showed that the physicochemical properties of bFGF/collagen composite sponge with high and low doses of bFGF have no significant difference from those of blank collagen sponge.SDS-page analysis indicated that the composite sponge has apparent strip in 18 kD.It was also found that bFGF/collagen composite sponge was responsible for significant effects on 3T3 cell proliferation in comparison to saline treatement(P <0.01,P <0.05).In the allergy study,during the periods of the induction and stimulation,no allergic reaction was found in bFGF/collagen composite sponge groups with high and low doses of bFGF,while severe reactions and inflammation occurred in positive group(2,4-dinitrochlorobenzene).Furthermore,pathological examination indicated the intact dermal structure and no sign of inflammation.Conclu-sion: The developed sponge has good physicochemical propertis and noticed cellular proliferation without dermal irritation.There is much potential to develop bFGF/collagen composite sponge into a new kind of wound dressing material for clinical use.

ABSTRACT
AIM:To study the mechanism of the unique export of one of human basic fibroblast growth factor (hbFGF) forms lacking the N-terminal nuclear localization signal (NLS),we high expressed and purified this hbFGF form in E.coli strain BL21(DE3).METHODS:The cDNA fragment of the hbFGF amplified by polymerase chain reaction (PCR) was cloned into the expression vector pET3c and expressed in BL21(DE3) by IPTG induction.The expressed hbFGF was purified by ionic exchange and heparin affinity chromatography from the supernatant of bacteria lysate.The mitogenic activity was measured by MTT.RESULTS:The expression level of hbFGF in E.coli was about 20% of the total cellular protein.The appreciable mitogenic activity of the purified hbFGF was comparable to that of hbFGF standard.CONCLUSION:The BL21(DE3)/ pET3c expression system could be used to high express hbFGF lacking NLS.The purified recombinant hbFGF was prepared and sufficient for further study.
ABSTRACT
In order to decrease the potential side-effects of human basic fibroblast growth factor (hbFGF) caused by its broadspectrum mitogenic activity, a single residue of hbFGF, the residue serine 108, was replaced with neutral alanine residue to construct a mutant of hbFGF (mhbFGF) with reduced mitogenic activity. The mutant was overexpressed in Escherichia coli BL21(DE3) by IPTG induction. The expression level of mhbFGF was about 30% of the total cellular protein. The expressed mhbFGF was purified by ionic exchange and heparin affinity chromatography from the supernatant of bacteria lysate. Measured by MTT method, the effect of mhbFGF on Balb/c 3T3 cell proliferation was much lower than that of wild-type hbFGF. The purified recombinant mhbFGF was prepared and sufficient for the following pharmacological and safety studies.
