OBJECTIVE: To observe the clinical effect of escin on patients with cutaneous pruritus caused by blood stasis and wind-dryness and to prove the theory that "wind should be treated by regulating blood disorder, and wind disappears after activating blood" in traditional Chinese medicine (TCM). METHODS: Fifty-one patients were randomly divided into escin-treated group (n=30) and loratadine-treated group (n=21). The patients in the escin-treated group were treated with escin for 4 weeks (300 mg, b.i.d.), and the patients in the loratadine-treated group were treated with loratadine (10 mg, q.d.). Symptom score reducing index (SSRI) was used to assess the pruritus degree, lesion range and lesion shape before the treatment, 2 weeks and 4 weeks after the treatment, respectively. RESULTS: Two weeks after the treatment, the effective rate of the escin-treated group was 63.3%, and the effective rate of the loratadine-treated group was 67.0%. Four weeks after the treatment, the effective rates were 86.7% and 80.0% in escin- and loratadine-treated groups respectively. There was no statistical difference in total scores of SSRI in two groups (P>0.05), and the scores of pruritus degree and lesion shape also had no statistical difference (P>0.05), while the score of lesion range of the escin-treated group was lower than that of the loratadine-treated group (P<0.05). CONCLUSION: Escin has satisfactory effect in treating pruritus caused by blood stasis and wind-dryness. The study confirms the TCM theory that "wind should be treated by regulating blood disorder, and wind disappears after activating blood".

OBJECTIVETo investigate the clinical effects of anterior transpediclar screw (ATPS) fixation in treating lower cervical spine fracture and dislocation.

METHODSFrom January 2009 to December 2011, 18 patients with lower cervical spine fracture and dislocation were treated with ATPS technique, including 12 males and 6 females, aged from 17 to 47 years old with an average of 38.2 years. Severity score of lower cervical spine injuries (SLIC) ranged from 6 to 9 points with an average of 7.5 points. According to ASIA grade of spinal cord injury, 2 cases were classified in grade A, 8 cases in grade B, 6 cases in grade C and 2 cases in grade D. X-ray and CT scan were done after surgery in order to evaluate the safety of ATPS and observe the stability and fusion of injured segment. Spinal cord function was evaluated according to ASIA grade at 3 months after operation and last follow-up.

RESULTSAll patients were followed up for 6 to 15 months with an average of 9.5 months. Three months after operation, in aspect of spinal cord function, 8 cases improved 1 grade, 2 cases improved 2 grades; and at final follow-up, 7 cases improved 1 grade, 4 cases improved 2 grades. All patients obtained bony fusion 6 to 8 months after operation with an average of 6.5 months. After operation, 1 case had transient hoarseness and recovered 2 months later;2 cases felt swallowing discomfort, but the symptoms disappeared after about 3 weeks by inhalation. No internal fixation breakage and loosening as well as nerve, blood vessel and esophageal injuries were found.

CONCLUSIONAs for three columns injury caused by lower cervical spine fracture and dislocation, treatment with anterior transpediclar screw reconstruction can achieve the effect of decompression thoroughly and restore the cervical spine height and physiological curvature. Moreover, this kind of treatment has good stability and can create the favorable conditions for the recovery of spinal cord function.

The occult sacral fracture has no symptoms of sacral nerves injuries and no severe pain. These occult sacral fractures have no significant fracture signs on plain X-ray film, which can be found only by spiral CT or MRI and be misdiagnosed easily. This article made a brief review on the diagnosis and treatment of this type of sacral fractures.

OBJECTIVETo systematically review the effectiveness of minimally invasive total hip arthroplasty (MIS-THA) versus traditional total hip arthroplasty (THA) in patients with hip diseases.

METHODSThrough a method of combining Free words and keywords,we searched databases including PubMed,The Cochrane Library, EMbase,Web of Science, CBM , CNKI and Wanfang Data for randomized controlled trials (RCTs) on the comparison between MIS-THA and THA for hip disease from inception to June, 2014. Two reviewers independently screened literatures according to the inclusion and exclusion criteria, extracted data and assessed the quality of the included studies according to the "bias risk assessment" tool recommended by Cochrane Handbook 5.0 for Systematic Reviews. Then, meta-analysis was performed using RevMan 5.3 software.

RESULTSThirteen RCTs involving 1 213 cases of surgeries and total 1 284 hips (MIS-THA: n = 631; THA: n = 653) were identified. The results of meta-analysis showed that statistically significant differences were found in Harris hip score on the 3rd month after operation [MD = 8.37, 95% CI (6.02,10.72)], Hematocrit [MD = 0.02, 95% CI (0.01, 0.03)] and Hemoglobin [MD = 0.50, 95% CI (0.16, 0.85)] at the 48th hour after operation, changed value of femoral offset [MD = 0.30, 95% CI (0.04, 0.56)] between two groups. In the change value of femoral offset, THA was better than MIS-THA; There were no statistically significant differences between two groups in Harris hip score at 1st year after operation [MD = 3.26, 95% CI (-3.25, 9.76)], WOMAC score [MD = -0.53, 95% CI (-3.67, 2.60)] and Oxford score [MD = 1.34, 95% CI (-3.46, 6.13)] at the 6th week after operation, Hematocrit at the 8th hour after operation [MD = -0.01, 95% CI (-0.02, 0.00)], the incidence of hip varus [RR = 0.82, 95% CI (0.45,1.52)] and dislocation [RR = 1.40, 95% CI (0.48, 4.12)].

CONCLUSIONTHA brings less trauma, less hemorrhage and better early clinical outcome compared with MIS-THA, but the difference of the complication rates between the two groups is similar.
