To evaluate the efficacy and safety of compound Decumbent Corydalis Rhizome (DCR) in treating patients with knee osteoarthritis (OA). Totally 79 patients with knee osteoarthritis were selected from out-patient and inpatient departments of West China Hospital and randomly divided into the test group and the control group. The test group (n = 41) was given Compound DCR with the dosage of 1.8 g · d(-1), while the control group (n = 38) was administered with diclofenac sodium with the dosage of 75 mg · d(-1). After 12 weeks of treatment, the total efficacy rates based on patients/physicians evaluation for experimental and control groups were 68.29%, 63.41% and 71.05%, 63.16%, respectively, without significant difference between the two groups. Both of the two groups showed significant improvements in the main efficacy indexes (pain on walking 20 m) and minor indexes (tenderness on palpation, Western Ontario and McMaster Universities OA index (WOMAC) and Short-Form Health Survey (SF-36 ), but without significant difference in efficacy between them. The incidence of related adverse events was 24.39% in the test group and 47.37% in the control group, respectively, with significant differences between the two groups (P < 0.05). In the controlled study, compound DCR is as efficient as diclofenac sodium but more tolerable, with a good clinical application prospect.

Objective: To observe the clinical efficacy of spleen-invigorating and qi-benefiting pediatric massage (tuina) for treating recurrent respiratory tract infection in children with cerebral palsy due to qi deficiency of spleen and lung. Methods: A total of 70 children with cerebral palsy who suffered from recurrent respiratory tract infection due to qi deficiency of spleen and lung were randomized into an observation group and a control group by the random number table method, with 35 cases in each group. Both groups were treated with conventional rehabilitation training, while the observation group was given additional spleen-invigorating and qi-benefiting pediatric massage, and the control group additionally took oral Yu Ping Feng granule. The clinical efficacy was evaluated by the total effective rate, traditional Chinese medicine (TCM) symptom score, and serum levels of immunoglobulin (Ig) A, IgM and IgG. Results: The difference in total effective rate between the two groups after treatment was statistically significant (P<0.05). After treatment, the TCM symptom scores in both groups decreased to varying degrees than those before treatment, and the intra-group differences were statistically significant (all P<0.01); the differences in the scores of various TCM symptoms between the two groups were statistically significant (all P<0.05). After treatment, the levels of IgA, IgM and IgG of the children in both groups increased to varying degrees, and the intra-group differences were statistically significant (all P<0.05). The between-group differences in the IgA, IgM and IgG levels after treatment were statistically significant (all P<0.05). Conclusion: Spleen-invigorating and qi-benefiting pediatric massage can effectively treat recurrent respiratory tract infection due to qi deficiency of spleen and lung in children with cerebral palsy, relieve the clinical symptoms and improve immune function, and thus is worthy of clinical promotion and application.

OBJECTIVETo study clinical effects of a new internal fixation by using a cable through the bone and Kirschner with a hole in the tail, for the treatment of patellar fractures.

METHODSFrom May 2012 to July 2013, thirty-four patients with patellar fractures were treated with cable through the bone and Kirschner with a hole in the tail. All the patients had close fracture,including 12 transverse fractures and 22 comminuted fractures. There were 18 males and 16 females, ranging in age from 26 to 81 years old, with an average of (46.0 ± 3.0) years old. After open reduction, two appropriate length of Kirschner with a hole in the tail were driven into the patella as perpendicular to the fracture line or the major fragments as possible. A transverse bone tunnel was then drilled with a Kirschner at one side of the patella. Then the cable, which was successively pulled through the bone tunnel and the hole of Kirschner, was crossed in a figure-eight over the anterior of the patella, tightened and fixated by special instruments. The Kirschner was clipped off on the edge of the hole. If it was a comminuted fracture, another cable was used to fasten the patella with cerclage. Postoperative evaluation was based on Bostman.

RESULTSAll the patients were followed up, and the duration ranged from 12 to 26 months, with a mean of (16.0 ± 2.0) months. Fractures healed in all the cases without such complications as infection, loosening of Kirschner and cable loop, and skin irritation. According to the Böstman score system, 33 cases got an excellent result, and 1 good.

CONCLUSIONThe cable through the bone and Kirschner with a hole in the tail is a simple, stable and effective method for the treatment of patellar fractures, especially the transverse fractures, with earlier knee exercise and fewer complications.

ObjectiveTo conduct a molecular epidemiological study on human metapneumovirus (hMPV) among pediatric patients in Guangzhou. MethodsA total of 1 840 clinical specimens were obtained from pediatric patients with respiratory infections in Guangzhou Women and Children' s Medical Center in 2010.hMPV was detected by real-time TaqMan RT-PCR in clinical specimens.F gene was amplified and the PCR-products were directly sequenced. ResultsIn 1 840 clinical specimens, 66 werehMPV-positive with a positive rate of 3.59％. hMPV was detected in all specimens except those collected in September and October, and the highest positive hMPV rate occurred in April (6.09％). The F genes of 3 randomly selected strains and hMPVgz01 ( isolated in 2008) were compared with subgroups A1, A2, B1,B2 and C, and the highest homology was with BJ1887 strain of genotype A2b (97％). The F genes of the randomly selected strains and hMPVgz01 were 99％ identical to each other. Sequences and phylogenetics analysis revealed that the epidemical strain in Guangzhou belonged to genotype A2b. ConclusionhMPV is prevalent in spring and summer among children in Guangzhou, and A2b is the predominant genotype.

U-shaped sacral fractures are rare and often difficult to diagnose primarily due to the difficulty in obtaining adequate imaging and the severe associated injuries.These fractures are highly unstable and frequently cause neurological deficits.The majority of surgeons have limited experience in management of U-shaped sacral fractures.No standard treatment protocol for U-shaped sacral fractures has been available till now.This study aimed to examine the management of U-shaped sacral fractures and the early outcomes.Clinical data of 15 consecutive patients with U-shaped sacral fracture who were admitted to our trauma center between 2009 and 2014 were retrospectively analyzed.Demographics,fracture classification,mechanism of injury and operative treatment and deformity angle were assessed.All the patients were treated with lumbopelvic fixation or (and) sacral decompression.EQ-5d score was applied to evaluate the patients' quality of life.Of the 15 consecutive patients with U-shaped sacral fracture,the mean age was 28.8 years (range:15-55 years) at the time of injury.There were 6 females and 9 males.The mean followup time was 22.7 months (range:9-47 months) and mean full weight-bearing time was 9.9 weeks (range:8-14 weeks).Ten patients received lumbopelvic fixation and sacral decompression,one lombosacral fixation,and 4 merely sacral decompression due to delayed diagnosis or surgery.The post-operation deformity angle (mean 27.87°,and range:8°-90°) of the sacrum was smaller than that pre-operation (mean 35.67;range:15-90) with no significance difference noted.At the latest follow-up,all patients obtained neurological recovery with different extents.Visual analogue score (VAS) was reduced from preoperative 7.07 (range:5-9) to postoperetive 1.93 (range:1-3).All patients could walk without any aid after treatment.Eight patients were able to care for themselves and undertook some daily activities.Five patients had returned to work full time.In conclusion,lumbopelvic fixation is an effective method for stabilization of U-shaped sacral fractures with fewer complications developed.Effective reduction and firm fixation are the prerequisite of early mobilization and neurological recovery.Sacral decompression effectively promotes neurological recovery even in patients with old U-shaped sacral fractures.

Objective To assess the income status of primary care providers and to explore the determinants of income in a county of Dali. Methods In August 2016, the questionnaire was employed to collect the data of income status of 191 rural health workers and 217 village doctors in the county. Results Through the study, we found that the income of rural health workers in the county was 34, 000 (26, 000, 46,000) yuan with a satisfaction rate of 62.3% (95% CI 55.4%～69.2%) and no change (74.7%) was seen in the income among majorities after implementing the Zero Mark-up Policy for essential medicines. For the village doctors, the income was 20,000 (15,000, 24,000) yuan with a satisfaction rate of 40.6% (95% CI 34.0%～47.1%) and a fall of the income was found in more than half of the doctors after the implement of the policy. Conclusion Health care workers in towns are quite satisfied with their income whereas those in health stations of villages are not content, compared with the average income at the national level. We should increase government's investments on grass-root healthcare team, improve the incentive pay plans and promote the integrated management of health facilities in towns and villages.
