Fu's subcutaneous needling (FSN) is a modern approach developed from traditional Chinese acupuncture. It could give some stimulation in the subcutaneous region that has a quick and long-lasting effect on soft tissue injuries and some of the internal medicine diseases. It is a safe approach without adverse reaction. Through analysis of the features and possible mechanism of FSN, it is believed that research on mechanism of FSN is beneficial to the development of modern medicine, especially to pain management.

Objective To observe and evaluate the effect of ultrasound guided percutaneous ethanol injection for hyperparathyroidism secondary to chronic renal failure. Methods Fifty-three patients with secondary hyperparathyroidism in Nanjing General Hospital Military Command from January 2011 to May 2013 were treated by percutaneous ethanol injection. The echogenicity, size and blood supply of parathyroid glands were observed by color Doppler ultrasound before and after treatment. Parathyroid hormone (PTH) and volumes of parathyroid glands were analyzed and compared with non-paired t test. Results Before treatment, the parathyroid gland volume was (5.28±0.84) cm3. The enlarged parathyroid glands had homogeneous hypoechogenicity and abundant blood supply, and the PTH was (1041.6±37.1) ng/L. After treatment, the size of solitary parathyroid gland was (3.93±0.67) cm3 which did not change significantly compared with that before treatment. The echogenicity of parathyroid glands enhanced and blood supply decreased after injection ethanol into solitary parathyroid. PTH [(509.2±27.6) ng/L] decreased obviously (t=3.792, P < 0.05). Conclusion Color Doppler ultrasound guided percutaneous injection of ethanol has an important role in the treating of secondary hyperparathyroidism and the curative effect can be observed timely.

Objective To investigate the clinicopathologic and immunohistochemical characteristics of breast carcinosarcoma with osteosarcoma components and its differential diagnosis. Methods The pathologic features and clinical manifestations of the two patients were retrospectively reviewed. Immunohistochemistry was performed and the literature was reviewed. Results Histopathologically, the neoplasm consisted of invasive ductal carcinoma of no special type and poorly ( case 1 ) or well (case 2) differentiated osteosarcomatoid elements. The morphological transition from carcinoma to sarcomatoid elements was seen. Immunohistochemically,the carcinoma cells were positive for CK and EMA , the sarcomatoid elements were stained positive for vimentin, and a few cells of two elements were positive for S-100 protein. Ki-67 and VEGF were over expressed in both elements of Case 1.In case2 Ki-67 expression was low in both elements and VEGF over expression was only seen in sarcomatoid elements. Some of the carcinoma cells were positive for ER. Conclusions Carcinosarcoma of the breast with osteosarcomatoid elements is a rare type of mixed epithelial/mesenchymal metaplastic breast carcinoma. The types and proportion of carcinoma and sarcomatoid elements determine the diagnosis.

Since the 1990s, studies on intemet addiction and mobile phone addiction have been concerned.Of which, internet addiction refers to internet surfing via personal computers, and mobile phone addiction is usually set within the phone calls and sending short message.In recent years, the time and frequency people using mobile phones have been increasing rapidly with the popularity of smart phone and the development of mobile Internet.Some severe cases show an excessive use of mobile phone, even dependent or addictive symptoms.These results in a variety of physical, psychological and social problems of the individuals.However, today's mobile phone dependence or addiction is beyond the scope of calling and texting, but more on the use of the network function.So it needs to redefine this behavior addiction and its criteria by combining both internet addiction and cell phone addiction.It is named as mobile internet addiction.The definition would help to study the mechanism of the development of mobile internet addiction, and provide theoretical foundations for developing effective intervention strategies.

Objective To establish the standard for quality control ofQingyan Granule. Methods The chief components of the preparation, Sophora Tonkinensis radix et rhizoma, Adenophorae radix, Lonicera japonica caulis, and Ophiopogonis radix were identified by TLC qualitatively. The contents of licorice glycosides and glycyrrhizic acid were determined by HPLC. The separation was performed on Thermo Syncronis C18 column (4.6 mm×250 mm, 5μm) with mobile phase consisted of acetonitrile with 0.05% phosphoric acid solution (A)-0.05% phosphoric acid solution (B), and gradient elution (0-8 min, 19%A;8-35 min, 19%→50%A). Detection wavelength was 237 nm, and flow rate was 1 mL/min.Results The spots in TLC were clear. There were spots with same color on the corresponding location of reference substance and reference herbal, negative control without interference. The linear range for licorice glycosides was 0.05-0.5μg (r=0.999 9). The average recovery was 99.97%, RSD=1.74% (n=9). The linear range for glycyrrhizic acid was 0.1-2μg (r=0.999 9). The average recovery was 99.74%, RSD=1.28% (n=9). Conclusion The method is simple, accurate, with high reproducibility, which can be used for quality control ofQingyan Granule.

Objective To observe the effect of leptin on glucose oxidation with increased mRNA expression of complete length long intracellular domain of leptin receptor ( OBRb) in primary cultured skeletal muscle cells. Methods Skeletal muscle cells were isolated from SD sucking rat and cultured in four groups (recombinant transfection, empty plasmid transfection, non-transfection and control).The recombinant with complete length OBRb cDNA or the empty plasmid were introduced into skeletal muscle cells by clonfectin when the cultured cells were 70% conlluency, leptin and regular insulin were applied into wells and incubated for 1 h, then D-[ U-I4C]-glucose was added into wells and incubated for 2 h. The radioactivity of collected 14CO2 was assayed by scintillation. Expression level of OBRb mRNA in transfected cells was assayed by RT-PCR. Results The ratios of OBRb intraceUular domain mRNA and p-actin mRNA in cells transfected with recombinant, transiected with empty plasimd, and non-transfected were 1.22?0.10,0.41?0.08 and 0.49?0.09, respectively.The expression of OBRb intraceUular domain mRNA in cells transfected with recombinants was significantly increased as compared to the other groups of cells (P

Objective To evaluate the protective effect of epigallocatechin gallate (EGCG) against interleukin (IL)-17-induced injury to keratinocytes,and to explore its mechanism.Methods Some cultured HaCaT cells were divided into 3 groups to be treated with IL-17 alone at concentrations of 50,70,90 μg/L,respectively,with those receiving no treatment as the blank control group.Some HaCaT cells were divided into 5 groups:IL-17 group treated with 90 μg/L IL-17 alone,IL-17 + EGCG group treated with 90 μg/L IL-17 and 60 μmol/L EGCG,IL-17 + SP600125 group treated with 90 μg/L IL-17 and SP600125 (a JAK signaling pathway inhibitor),IL-17+ EGCG + anisomycin group treated with 90μg/L IL-17,60xmol/L EGCG and anisomycin (a Janus kinase signaling pathway activator),and blank control group receiving no treatment.After different durations of treatment,CCK-8 assay was performed to evaluate cellular proliferative activity,flow cytometry to detect cell apoptosis,enzyme-linked immunosorbent assay (ELISA) to measure expression levels of IL-6,IL-23 and IL-8,and Western-blot analysis to determine protein expressions of c-Jun N-terminal kinase (JNK) and phosphorylated JNK (P-JNK).Results IL-17 promoted cellular proliferation of HaCaT cells,and the proliferation rate,which was correlated with the concentration of IL-17,reached the maximum in the 90-μg/L IL-17 group (P ＜ 0.05).EGCG at 60 μmol/L significantly inhibited cellular proliferation of,promoted apoptosis in,and reduced IL-6,IL-23 and IL-8 expressions in,HaCaT cells induced by 90 μg/L IL-17 (all P ＜ 0.05).Compared with the IL-17 group,the IL-17 + EGCG group and IL-17 + SP600125 group both showed significantly decreased P-JNK expression,cell proliferation rate and IL-6,IL-23 and IL-8 expression levels (all P ＜ 0.05).However,compared with the IL-17 + EGCG group,the IL-17 + EGCG + anisomycin group showed significantly increased protein expression of P-JNK,cell proliferation rate and IL-6,IL-23 and IL-8 expression levels (all P ＜ 0.05).Conclusion EGCG protected against IL-17-induced injury to HaCaT cells,such as abnormal cell proliferation,apoptosis and inflammatory response,likely by inhibiting the JNK signaling pathway.
