Objective:To explore the clinical efficacy of scalp acupuncture plus speech rehabilitation in treating Broca's aphasia after cerebral stroke, for providing novel evidences for the treatment. Methods:Ninety-one eligible patients with Broca's aphasia after cerebral stroke were randomized into an observation group and a control group. Forty-six cases in the observation group were intervened by scalp acupuncture plus speech rehabilitation, while 45 cases in the control group were treated by speech rehabilitation alone. The aphasia battery of Chinese (ABC) and Boston diagnostic aphasia examination (BDAE) were adopted to evaluate the clinical efficacy. Results:After the treatment, the scores of oral expression, reading and writing and global score in the observation group were significantly higher than those in the control group (allP<0.05). There was a significant difference in comparing the BDAE grading between the two groups after the treatment (P<0.05). After intervention, the basically-recovered plus markedly-effective rate was 45.7% in the observation group versus 24.4% in the control group, and the between-group difference was statistically significant (P<0.05). Conclusion:Scalp acupuncture plus speech rehabilitation is effective in treating Broca's aphasia after cerebral stroke, and worth promoting.

Objective to observe the efficacy and application value of PFNA and Gamma in the treatment of intertrochanteric fractures in elderly. Methods 100 patients with intertrochanteric fractures were divided into PFNA group and Gamma group, who received PFNA treatment and Gamma treatment respectively. And the operation status of patients at different ages,postoperative recovery,and complications were observed. Results The operation time,intraoperatve blood soss of PFNA group were lower than those of Gamma group(P<0. 05). There was no significant difference in fracture healing time. The Harris score of the over 75s in PFNA group was higher than that in Gamma group(P<0. 05),and the complications were less than Gamma group(P<0. 05). Conclusion PFNA was suitable for the patients at differ-ent ages with the advantages of more rigid fixation,good anti-rotation,fewer trauma and fewer complications.

Objective: To explore the relationship between the PTCH1 mutation and the expression of bcl-2, filaggrin, and loricrin in the keratocystic odontogenic tumour (KCOT), as well as the effects of the mutated PTCH1 on the epithelial proliferation and differentiation.Methods: The samples were collected from 20 cases of KCOT with mutated PTCH1, as well as 20 cases without mutation.All the samples were analyzed with immunohistochemical staining, for the purpose of investigating the expression of bcl-2, filaggrin, and loricrin.Results: In the samples with mutated PTCH1, the epithelia of 60% (12/20) cases expressed intensively positive bcl-2 staining, 20% (4/20) expressed moderate staining, and 20% (4/20) weak staining, but no negative bcl-2 staining samples were investigated;it was significantly different from the samples without PTCH1 mutation, in which 20% (4/20) expressed intensive staining, no moderate staining, 50% (10/20) weak staining, and 30% (6/20) negative staining were investigated (U=72, P=0.001).For the expression of filaggrin, 55% (11/20) of samples with PTCH1 mutations were stained weakly and 45% (9/20) showed negative staining, while in the samples not harboring PTCH1 mutations, 30% (6/20) cases showed moderate positive staining, 40% (8/20) weak staining and 30% (6/20) negative staining, no intensive staining was investigated (U=182, P=0.48).The loricrin expressed in all the layer of the epithelia in all the samples, while the filaggrin was mainly loca-lized within 1-4 layer cells of the epithelia.The differences of the expression of filaggrin and loricrin between the samples with mutated PTCH1 and without mutated PTCH1 displayed no significance.Conclusion: In the epithelia of KCOT, the bcl-2 expression was significantly associated with the PTCH1 mutation, which suggested that the mutated PTCH1 gene perhaps promotes the proliferation of KCOT epithelium.

Objective To evaluate the inflammatory response in the airway of healthy rats following exposure to motor vehicle exhaust. Methods Sixty healthy SD rats(30 males and 30 females,aged 6 weeks) were randomly divided into 6 groups. The rats in the exposed groups were placed by the main traffic road and those in the control group were placed in the normal laboratory environment. The bronchoalveolar lavage fluid(BALF) was analyzed on the 14th,30th and 90th day of exposure .WBC,NO,TNF-?,and IL-8 in BALF of the rats in each group were tested. Results The NO content [(9.75?4.78) ?mol/L] in BALF of the rats in the group exposed for 30 days was obviously higher than that in the control group [(4.40?1.45) ?mol/L],but there was no any obvious difference between the two groups in terms of the content of TNF-? and IL-8 in BALF. Conclusion This study demonstrates that exposure to vehicle exhaust can induce inflammatory response in healthy rats,the on-the-spot experiment on animal exposure can be used to observe early respiratory tract inflammation and 30 days of exposure is the sensitive period for the change of the inflammatory indicators.

Karacoline is a compound found in the plant Aconitum kusnezoffii Reichb. Although Aconitum kusnezoffii Reichb is widely used for the treatment of pain, very few studies have been carried out on the use of karacoline due to its potential toxicity. In this study, we selected key matrix metalloproteinases (MMPs), collagen II, and aggrecan as targets due to their association with intervertebral disc degeneration (IDD). Using these targets, we then used network pharmacology to predict a series of molecules that might exert therapeutic effects on IDD. Of these molecules, karacoline was predicted to have the best effect. Tumor necrosis factor (TNF)-αis known to promote the degeneration of the extracellular matrix in IDD. We therefore applied different concentrations of karacoline (0, 1.25, or 12.88μM) along with 100 ng/mL TNF-αto rat nucleus pulposus cells and found that karacoline reduced the expression of MMP-14 in IDD by inhibiting the nuclear factor (NF)-κB pathway, while collagen II and aggrecan expression was increased. This suggested that extracellular matrix degradation was inhibited by karacoline (P<0.05). Our data therefore reveal a new clinical application of karacoline and provide support for the use of network pharmacology in predicting novel drugs.

Objective To observe the effect of tanshinone ⅡA on renal transforming growth factor beta 1 (TGF-β1) and nuclear factor-kappa B (NF-κB) p65 mRNA and protein expression in diabetic nephropathy (DN) rats, thus to evaluate the therapeutic effect and mechanism of tanshinone ⅡA. Methods SD rats were used as the experimental animal. DN rat model was induced with 40 mg/kg of streptozocin ( STZ) . The rats were randomized into normal group, model group, and tanshinone ⅡA ( 10 mg·kg -1·d -1, im) group. On the experimental day 30, we examined the body weight, water in-take volume, 24-hour urine protein, fasting glucose ( Glu) , serum creatinine ( Cr) , blood urea nitrogen ( BUN) , total protein ( TP) and albumin ( Alb). Renal slices after periodic acid Schiff staining ( PAS) were used for the observation of renal pathology. Semi-quantitative reverse transcription polymerase chain reaction ( RT-PCR) was used for the detection of renal TGF-β1 and NF-κB p65 mRNA expression, and Western blotting method was used for the measurement of TGF-β1 and NF-κB p65 protein expression in rats of different groups. Results Compared with the normal group, body weight was decreased, water in-take volume and 24-hour urine protein were increased, serum Glu, Cr, and BUN levels were elevated, TP and Alb levels were decreased, renal pathological damage occurred, and renal TGF-β1 and NF-κB p65 mRNA and protein expressin were promoted in the model group (P<0.05 or P<0.01). Tanshinone ⅡA group had an effect on decreasing water in-take volume, 24-hour urine protein, serum levels of Glu, Cr and Bun, increasing TP and Alb levels, relieving renal pathological damage, and reducing the protein and mRNA expression of renal TGF-β1 and NF-κB p65 ( P<0.05 or P<0.01 compared with the model group). Conclusion Tanshinone ⅡA has protective effect on kidney probably through inhibiting renal TGF-β1 and NF-κB p65 expression in DN rats.

Purpose To study the clinicopathologic and genetic features of clear cell sarcoma of the gastrointestinal tract. Methods One case of clear cell sarcoma of the gastrointestinal tract was analyzed by histology, immunohistochemistry, fluorescence in situ hy-bridization ( FISH) , with review of relevant literatures. Results A female patient was admitted to the hospital with a history of 1-week abdominal pain. Computed tomography revealed a mass in right hemicolon. A grey-white ulcerated mass was observed in the colon, in-volving the entire thickness of the colon wall extending into the subserosa. Microscopically, medium-size oval or round cells were ar-ranged in sheets and scattered osteoclast-like multinucleated giant cells were also presented. Immunohistochemically, the tumor cells were strongly positive for S-100 protein, but negative for HMB-45, Melan-A, CD117, CD1a and PCK. FISH showed the rearrangement of EWSR1 in 74% of the neoplasm cells. Conclusions Clear cell sarcoma of the gastrointestinal tract is an extraordinarily rare gastro-intestinal neoplasm that shows peculiar histopathological, immunohistochemical, ultrastructural, and genetic features. Whether clear cell sarcoma-like gastrointestinal tumor represents a distinct entity awaits larger series, including cytogenetic or molecular biological in-vestigation.
