Objective To investigate histopathological changes and expression of integrin ?1 of sternomastoid muscle,and probe the mechanism and significance during disease process in congenital muscular torticollis(CMT).Methods Histopathological changes of sternomastoid muscle section stained with HE and Gomori silver staining were observed and the expression of integrein ?1 with immunohistochemistry was detected,and the expressive quantity and distribution with image analysis system was quantitive analyzed.Results 1.With light microscopy observation,the results showed that the fibrous degeneration of sternomastoid muscle could be summed up 2 kinds: A category displayed the myocytes atrophyed,and there were lots of connective tissue hyperplasy around myocytes,and the direction of fibrous arrangement was disordered,meanwhile there were lots of vessels and nervers hyperplasy,and eventually the myocytes shrank back and disappeared.B category displayed that the structure of cross striation or sarcomere disappeared or changed,and myocytes could maintained the outline and the sarcolemma were integrated,and then fibrous pathological changes of myocyte took place,and there were lots of fibroblast-like that had much more enations between fiber bundles.With Gomori silver staining,the major changes of fibrotic sternomastoid muscle showed that there were lots of collagenous fibers hyperplasy.The arrangements of collagenous fibers were disordered in A category and were well-arranged in B ca-tegory.2.With immunohistochemistry,the results showed the expression of integrin ?1 was weak positive in normal control group(125.7?5.167).In diseased groups,the results showed 3 different extents:the expression of integrin ?1 displayed stronger positive in A category myocytes(30.15?6.543),and the level of expression was significantly different from normal controls(P0.05).Conclusions The fibrous pathological changes of sternomastoid muscle are a complicated and gradually process,which may has different mode,and ingetrin ?1 may participated the process of pathological changes.

Twenty-three patients with pain from osteoporotic vertebral fractures,aged 65-90 yr,weighing 51-78 kg,received an image intensifier-assisted nerve-root block with a 6-8 ml mixture of 0.5 ％ lidocaine,mecobalamine 0.5 mg and betamethasone sodium phosphate injection 5.26 mg in a prone or lateral position.The VAS scores before operation,at 0,1 week,1 and 3 months after operation were 8.6 ± 0.9,1.5 ± 0.7,2.8 ± 0.9,1.6 ± 0.5 and 2.5 ± 0.7,respectively.VAS scores were significantly lower at each time pint after operation than before operation (P ＜ 0.05).According to modified MacNab standard,the effectiveness of treatment was rated as excellent/good in 87％ of the patients.No complication such as bleeding,hematoma,infection,pneumothorax,hemopneumothorax,headache was found during or after operation.Selective nerve-root block is effective in the treatment of pain resulting from osteoporotic vertebral fractures in patients.

OBJECTIVETo summarize the clinical application result of the selective nerve root blocks in limited operation of the lumbar spine.

METHODSFrom January 2008 to October 2012,68 patients with lumbar spinal canal stenosis with multiple levels were underwent the selective nerve root blocks in limited operation of the lumbar spine,including 47 males and 21 females with an average age of 56 years old ranging from 45 to 80. After never roots blocks,64 cases were positive for limited operation of the lumbar spine; the other 4 cases were negative and abort the operation.

RESULTSThe nerve roots block operation smoothly and no complications related to the nerve roots block occurred. There was no neurologic injury complication in this study. Follow-up period ranged from 16 to 45 months postoperatively (means, 32 months). The recovery effect was calculated with Macnab scores, the result was excellent in 44 cases, good in 18 cases, poor in 1.

CONCLUSIONOperative treatment for lumbar spinal canal stenosis with multiple levels is focused on the areas causing symptomate neural compression rather than prophylactic decompression at areas of nonsymptomatic disease. Application of selective nerve root blocks can accurately judge the responsible vertebral body and pain source and improve the curative effect of limited operation of the lumbar spine

OBJECTIVETo summarize the clinical application results of the repair soft tissue defect in contralateral leg with a cross-leg soleus muscle flap pedicle transplantation.

METHODSFrom January 2008 to January 2013, 8 patients with soft-tissue defect in lower leg underwent reconstruction with a cross-leg soleus muscle flap pedicle transplantation (without microvascular anastomoses). There were 7 males and 1 female, aged from 20 to 49 years old with an average of 31.8 years. The operative time after injury was from 2 to 8 weeks with the mean of 46 days. The soleus muscle flap was transposed across to the contralateral leg defect area, then immediate to perform the coverage of the muscle flaps by a meshed split-thickness skin graft. The donor site was closed directly.

RESULTSAll the muscle flaps had survived completely. In one case, recipient area edge had a less exudate from drainage hole everyday, the incision spontaneously was healed after 2 week's changing dressing. Follow-up period ranged form 1.5 to 4 years with an average of 2.5 years postoperatively. The tibia and fibula fractures were healed well. A good contour was achieved at the recipient area. According to LEM standard, 2 cases got excellent results, 5 good and 1 fair.

CONCLUSIONSoleus flap pedicle transplantation is very suitable to repair the soft tissue defect of the injuried leg only one main blood vessel, and can reduce the damage of donor area.

OBJECTIVETo observe the effect of Yiqi Huoxue Qingre Huashi Recipe (YHQHR, a recipe capable of supplementing qi, activating blood, clearing heat, and dissipating dampness) on ulcer healing and Helicobacter pylori (Hp) eradication rate in Hp positive peptic ulcer patients, and to explore coccoid Hp occurrence in the eradication.

METHODSTotally 80 Hp positive peptic ulcer patients were assigned to the treatment group and the control groups by random digit table, 40 in each group. All patients received standard triple therapy of Western medicine for 2 successive weeks. Those in the control group additionally took omeprazole enteric coated tablet, 20 mg each time, once per day for 4 successive weeks. Those in the treatment group additionally took YHQHR, twice per day for 6 successive weeks. The ulcer healing was observed and recorded by gastroscope after discontinued medication of 14 days. The effective rate of ulcer healing under endoscope was statistically calculated. Rapid urease test (RUT) was performed in one small piece of tissue from corpora ventriculi and sinuses ventriculi using 14C breathe test (UBT). Gastric juice was collected from the stomach. Hp urease gene amplification test (urea A-PCR) was performed in living tissue from gastric antrum. Results obtained from the above three test methods were recorded and assessed to decide the final eradiation rate. Gastric mucosa tissue was observed under electron microscope,attempting to find non-eradicated Hp, which was further observed.

RESULTSThe total curative effect under gastroscope was 97.5% (39/40 cases) in the treatment group, obviously higher than that in the control group (80.0%, 32/40 cases) (P < 0.05). The eradication rate of Hp was 75.0% (30/40 cases), obviously better than that of the control group (52.5%, 21/40 cases) (P < 0.05). The total positive Hp numbers after treatment was 14C UBT (12), RUT (8), and urea A-PCR (27), respectively. The Hp positive rate detected by 14C UBT and RUT was lower than the Hp positive rate detected by urea A-PCR (P < 0.05). Rod-like and coccoid Hp bacteria could be observed under electron microscope.

CONCLUSIONYHQHR combined standard triple therapy was more effective than standard triple therapy alone in promoting ulcer healing and elevating the eradication rate of Hp.

OBJECTIVETFo compare the efficacy and complications rate of intramedullary (IM) nailing or K-wire versus plating fixation for clavicular fractures.

METHODSPubmed, Embase, Cochrane Library databases, CNKI, VIP and Wangfang databases were searched to find all randomized or quasi-randomized controlled trials of clavicle fractures using plating versus IM nailing or K-wire. The methodologic quality of the studies was assessed. After independent study selection by 2 authors ,data were collected and extracted independently. Outcomes of postoperative shoulder functional measurement, the efficacy and information of the operation and complications rate were meta-analyzed using RevMan 5 software.

RESULTSNine hundreds and seventy-six patients in 10 randomized controlled trials (RCTs) and 3 quasi-RCTs were involved in the meta-analysis,of which 5 studies compared the K-wire and the plating fixations and 8 studies compared the IM nailing and the plating fixations. The overall odds ratio(OR) (with 95% CI) of the operation efficacy for K-wire versus the plating was 3.79 (1.93, 7.46). The overall weighted mean difference (with 95% CI) of Constant Shoulder score for plating versus IM fixation was -1.39 (-3.43, 0.65) in 6 studies. The overall OR of the plating versus IM nailing was 9.34(2.70, 32.32) for the overall major complications in 5 studies and 5.04 (1.52,16.77) for the revision rate in 5 studies.

CONCLUSIONThe current limited evidences suggested that the IM fixation could reduce the incidences of the overall major complications and the revision surgery, while the post-operative efficacy of the plating was superior to the K-wire. More high quality RCTs are still needed in the future.

OBJECTIVETo observe the temperature change of traditional silver needle in the human body during the burning of moxa ball.

METHODSThirty-six healthy volunteers were randomly divided into a single-needle group and a multi-needle group, 18 cases in each group. For both groups, one silver needle (18 cm in length, 1.1 mm in diameter), which was adopted in this research to measure the temperature change, was punctured in the insertion point of the volunteer (inside the top of the left buttock, 7 cm under the edge of the highest point of the iliac crest, 7 cm lateral to the dorsomedian line), then another four silver needles were punctured 2 cm respectively anterior, posterior and lateral to the insertion point in the multi-needle group, and all the silver needles were inserted with 6 cm depth. Afterigniting the 1.3 g moxa ball on the needle tail, the temperature of the measuring points that were 3 mm, 33 mm, and 63 mm above the silver needle tip were recorded separately by digital temperature measuring instrument.

RESULTSThe peak temperature of the three measuring points in the single-needle group was all around 41 degrees C, while those in the multi-needle group were around 43 degrees C, which had significant differences (all P < 0.05), but no significant differences among the highest temperature of the measuring points in the same group could be found (all P > 0.05). The highest temperature of moxa ball in the single needle group was (611.16 +/- 6.91) degrees C, while that of the central moxa ball in the multi-needle group was (628.94 +/- 8.99) degrees C, the difference of which was significant difference (P < 0.01).

CONCLUSIONThe temperature conductivity of the silver needle is very well, so the heat of the moxa ball could pass from the tail of needle to the tip during the warming treatment. The peak temperature on the body, tip of the silver needle in the multi-needle group is higher than those in the single needle group. Also, the peak temperature of multi-moxa ball is higher than that of single moxa ball.
