Objective To investigate the possible existence of HBoV in children with acute respiratory infections in Nanjing area and explore its relationship with clinical characteristics.Methods A total of 397 nasopharyngeal secretion samples were collected from children with acute respiratory infection,admitted from July 2009 to June 2010 in Nanjing Children'S Hospital affiliated to Nanjing Medical University,and 50 cases of children without symptoms of respiratory infection were recruited as control group,whose nasopharyngeal secretion samples were also collected.HBoV was determined by real-time fluorescence quantitative PCR.MP and CT were detected by real-time fluorescence quantitative PCR in those HBoV-positive samples.RSV,ADV,IVA,IVB,PIV-1,PIV-2,PIV-3 and hMPV were detected by direct antigen-specific immunofluorescence assays.HBoV NP-1 fragments were amplified and sequenced in 5 HBoV positive samples randomly selected.The results were compared with the known GenBank sequence,and thereby the phylogenetic tree was established.The epidemiological characteristics,clinical presentation and the final clinical diagnosis of HBoV were analyzed according to the clinical data of the HBoV-positive patients.Results Thirty-three HBoV-positive cases were detected by real-time fluorescence quantitative PCR method with a positivity rate of 8. 3% ( 33/397 ). Among the 33 HBoV-positive cases, 19 cases (57.6%) were multiple infections with HBoV and other pathogens, the top three of which were MP (27.3% ,9/33 ),RSV (24.2% , 8/33 ) and PIV-3 ( 12. 1% ,4/33 ). Affected children aged from 7 to 36 months old accounted for 75.8% of the total ( 25/33 ). The measured HBoV NP-1 gene sequences of 5 specimens were consistent,indicating a high homology (99% to 100% ) with the stl, st2 and WHL-1. Conclusions HBoV is one of the pathogens of children's acute respiratory infections in Nanjing. HBoV NP-1 gene is highly conserved,with little variation in different seasons and in different regions and therefore can be used as a marker for real-time fluorescence quantitative PCR and other methods.

Objective: To observe the effect of acupuncture-moxibustion on the expression of insulin-like growth factor-1 (IGF-1) and suppressor of cytokine signaling-2 (SOCS2) in colonic mucosa of rat models of ulcerative colitis (UC), and explore the mechanism of acupuncture- moxibustion therapy in treating UC. Methods: The rats were randomized into a normal control (NC) group, a model control (MC) group, an herb-partitioned moxibustion (HPM) group and an electroacupuncture (EA) group, 8 in each group. The rat models of UC were established by immunological methods combined with local stimulation. The rats in the HPM and EA groups were given herb-partitioned moxibustion and electroacupuncture treatments respectively, once every day, lasting for 14 d. The morphological variations of rat's colonic mucosa were observed under light microscope; the colonic mucosal mucin was detected by PAS-AB and HID-AB staining methods; the expression of IGF-1 and SOCS2 was assayed by the immunohistochemical method. Results: In the rat models of UC, ulceration and inflammation of the colon were revealed by light microscope. The concentration of colonic mucosal mucin was reduced (P<0.01), while the expression of IGF-1 had an increase (P<0.01), and the expression of SOCS2 was reduced (P<0.01). After HPM or EA treatment, the pathological injuries of colonic mucosa had improved, the concentration of mucin increased (P<0.01), the expression of IGF-1 decreased (P<0.01), and the expression of SOCS2 increased (P<0.01). Conclusion: The secretion of mucosal mucin in rat UC decreased, the expression of IGF-1 was significantly higher, while the expression of SOCS2 was remarkably lower; both HPM and EA can help improve the damage of colonic mucosa in rat UC, and modulate the secretion of mucin, as well as regulate the expression of IGF-1 and SOCS2 in the colonic mucosa.

OBJECTIVETo establish a new method for simultaneous determination of shanzhiside methyl ester, chlorogenic acid, 8-O-acetyl shanzhiside methylester, forsythiaside B, rutin, acteoside and galuteolin in Lamiophlomis rotata.
METHODSeparation was performed on a Welchrom-C18 chromatographic column with acetonitrile-0.1% orthophosphoric acid as mobile phasewith gradient elution. The flow rate was 1.0 mL x min(-1). The column temperature was 30 degrees C, and the detection wavelength was set at 238 nm, 330 nm and 350 nm.
RESULTThe seven compounds were well separated with good linear correlations. The mean recoveries of seven compounds were 96.47%-102.2% (RSD 0.70%-2.2%).
CONCLUSIONThere were good correlations among the seven compounds in the samples of aerial parts. The mean sum of shanzhiside methyl ester and 8-O-acetyl shanzhiside methylester in samples of aerial parts is 1.44%. The aerial parts have more kinds of composition and with higher content than that of underground parts in L. rotata, which was reasonable for the resonable use of the aerial part as medicinal part. The method was simple, repeatable and stable, which could be used for identification and quality evaluation of L. rotata.

OBJECTIVETo explore the operation methods and clinical effects of transfer of the medial half of the coracoacromial ligament to reconstruct the coracoclavicular ligament in treating complete acromioclavicular joint dislocation.
METHODSFrom January 2006 to June 2012,26 patients with acute complete acromioclavicular joint dislocation underwent surgery. Transfer of the medial half of the coracoacromial ligament to reconstruct the coracoclavicular ligament, additional clavical hoot plate and Kirschner wires fixation, were performed in all the patients. Among the patients, 18 patients were male and 8 patients were female, with an average age of 36.7 years old (ranged from 25 to 51 years). The duration from injury to operation was from 3 to 12 days with an average of 5 days. According to the Rockwood classification, 4 cases were grade III and 22 cases were grade V . Clinical manifestation included local swelling, tenderness with snapping, limitation of shoulder joint motion. In preoperative bilateral shoulder joint X-rays, the injured coracoclavicular distance was (16.2 ± 5.0) mm which was significantly wider than that of uninjured sides (7.6 ± 1.0) mm. Clinical results were evaluated according to X-rays and Constant-Murley score.
RESULTSAll incisions obtained primary healing after operation without complication of infection, internal fixation breakage, redislocation. All the patients were followed up from 12 to 30 months with an average of 18 months. Kirschner wires and internal fixation plate were removed at 1 month and 8-10 months after operation, respectively. At final follow-up, the motion of shoulder joint recovered to normal and a no pain joint was obtained. According to Constant-Murley score, 24 cases got excellent results and 2 cases good. There was no significant difference after operation between the injured coracoclavicular distance and the uninjured contralateral side [(7.7 ± 1.2) mm vs (7.6 ± 1.0) mm), P > 0.05].
CONCLUSIONTransfer of the medial half of the coracoacromial ligament to reconstruct the coracoclavicular ligament, additional fixation using hook plate and Kirschner wires is the effective surgical method in treating complete acute acromioclavicular joint dislocation.

Objective To investigate the manifestations of esophageal motility disorders and evaluate the association between them and dysphagia, laboratory tests and other accessory examinations in patients with Sj(o)gren's syndrome (SS). Methods Esophageal manometry was performed in 31 patients with SS and 18 healthy volunteers by the step pull-through method. Results Decreased upper esophageal sphincter pressure was detected in 19 of the 31 patients (61%) with SS, while 4 of 18 (22%) in controls. The frequency was significantly higher in patients than in healthy controls (P=0.008). Fifteen of 31 patients (48%) showed various patterns of esophageal dysfunction including ineffective esophageal motility in 6 patients, nutcracker esophagus in 3 patients and nonspecific dysmotility in 6 patients. No major differences were found in esophageal parameters (peak amplitude, wave duration and velocity) when comparing primary SS with secondary SS. These esophageal abnormalities were not correlated with clinical manifestations, laboratory examinations and other auxiliary examinations. Conclusion Patients with SS may have esophageal motility disorders, which can presents with different patterns.
