OBJECTIVETo investigate clinical effects and mechanism of Tangweikang (TWK) in treating diabetic gastroparesis.

METHODSNinety diabetic gastroparesis patients were randomly assigned to 3 groups. Besides conventional hypoglycemic treatment, the 30 patients in the treated group were given TWK and the 30 in the control group were given Domperidone additionally, while to the 30 in the blank group, no additional drug was given. The clinical efficacy and the changes in level of motilin and gastric emptying rate were observed.

RESULTSTWK showed significant effects in improving clinical symptoms of patients, increasing gastric emptying rate, promoting gastrointestinal kinetics, shortening gastric emptying time and was beneficial to the control of blood sugar, including the 2 h post-prandial blood sugar and fructosamine. The curative rate and total effective rate in the treated group were 63.33% (19/30) and 93.33% (29/30) respectively, significantly different to those in the control group 26.67% (8/30) and 63.33%, also different to those in the blank group 23.33% (3/ 30) and 10.00%, respectively (P < 0.01). The clinical efficacy in the treated group was superior to that in the other two groups.

CONCLUSIONTWK has favorable therapeutic efficacy in treating DGP.

OBJECTIVETo compare the effect of transumbilical single-site single-port with that of transumbilical single-site double-port laparoscopic varicocelectomy in the treatment of varicocele in adolescents.

METHODSWe randomly assigned 80 varicocele patients aged 10 - 16 years to two groups of equal number to receive transumbilical single-site single-port and single-site double-port laparoscopic varicocelectomy, respectively. We compared the operation time, postoperative hospital stay, incisional pain, complications and satisfaction with the abdominal cosmetic outcomes between the two groups.

RESULTSAll the operations were successfully performed. The double-port group showed a significantly higher score on the Visual Analogue Scale than the single-port group (4.8 +/- 1.4 vs 3.6 +/- 1.1, t = -4.986, P < 0.01), but there were no significant differences between the two groups in the operation time ([29.8 +/- 4.2] vs [31.2 +/- 4.6] min, t = 1.383, P = 0.171), postoperative hospital stay ([1.95 +/- 0.7] vs [1.82 +/- 0.8] d, t = -0.784, P = 0.436), complications (0 vs 0) and scores on the satisfaction with abdominal cosmetic outcomes (4.6 +/- 0.6 vs 4.8 +/- 0.5, t = 1.253, P = 0.214). No recurrence, umbilical hernia, hydrocele and orchiatrophy were found in the two groups of patients at 6 months after operation, and no visible scar was observed on the abdominal surface.

CONCLUSIONWith strict surgical indications, single-site single-port and single-site double-port laparoscopic varicocelectomies have similar clinical effects in the treatment of varicocele, which leave no scar on the abdominal surface. Single-site double-port laparoscopy needs no special instruments and therefore is worthier of wide clinical application.

OBJECTIVETo explore the clinical effects and significances of a cervical anterior Hybrid technique with posterior longitudinal ligament retained in treating cervical spondylosis.

METHODSThe clinical data of 138 patients with cervical spondylosis underwent cervical anterior Hybrid surgery were retrospectively analyzed from March 2009 to March 2013. There were 52 males and 86 females,the age ranged from 36 to 58 years old with an average of 45.3 years. Course of disease was from 3 to 16 months. Cervical spondylosis classification included 22 cases with nerve root type, 68 cases with myelopathic type, 48 cases with mixed type. All patients were treated with the primary Hybrid surgery and their cervical posterior longitudinal ligaments were retained in anterior decompression. JOA score and image examination were used to evaluate clinical effect, and image examination included range of motion of the replacement segment, range of motion of the whole cervical spine, the sagittal diameter of the spinal cord before and after operation.

RESULTSAll operations were successful and operation time was 60 to 125 min (averaged 90.6 min), perioperative bleeding was 10 to 60 ml (averaged 30.1 ml). All patients were followed up from 12 to 48 months with an average of 22.2 months. All pathological segments obtained fully decompression, reserved posterior longitudinal ligament had no obvious hypertrophy, proliferation and calcification. The prosthesis had good location and the incision healed well without complications. Upper limbs root symptoms were completely relieved in the patients with cervical spondylotic radiculopathy, muscle strengths and sensations got different recovery in the patients with cervical spondylotic myelopathy. JOA score was increased from preoperative 8.62±1.22 to final follow-up 14.26±1.47 (P<0.05). Artificial intervertebral discs were stabilized in the patients, the replacement segment and range of motion of whole cervical spine were respectively (14.2± 5.6)° and (33.8±10.3)°, there was no significant differences between preoperative and postoperative (P>0.05). Spinal cord sagittal diameter was increased from preoperative (5.2±1.3) mm to postoperative (8.8±0.5) mm (P<0.05).

CONCLUSIONAnterior cervical Hybrid surgery with posterior longitudinal ligament retained can achieve fully decompression and good clinical efficacy, we recommend retaining the normal posterior longitudinal ligament in surgery as complete as possible.

OBJECTIVETo study the clinical efficacy of Shufeng Liangxue Decoction (SLD) in treating hormone dependence dermatitis (HDD).

METHODSOne hundred and sixteen patients with HDD were randomly assigned to two groups. Both were treated with symptomatic Western medical therapy, including oral taken of loratadine 10 mg, and intravenous injection of 10% calglucon 10 mL and vitamin C 3.0 g adding in 20 mL 50% glucose, once per day, and to the test group, one dose of SLD consisting of imperata rhizome 30 g, rehmannia root 30 g, moutain bark 15 g, schizonepeta spike 15 g, divaricate saposhnikovia root 10 g, scutellaria root 15 g, forsythia fruit 15 g, cape-jasmine fruit 10 g, red peony root 10 g, white-stiff silkworm 10 g, broom cypress fruit 15 g, Indian bread 15 g and licorice root 10 g, was given every day by decocting with water. The course of treatment was 4 weeks. Symptoms of patients, including redden-swollen skin, capillary dilatation, inflammatory papula, itching and other discomfort sensation (pain, burning, dry, buckled) were scored before and after treatment according to their severity. The efficacy was evaluated by the change in scores of symptoms, the adverse reactions occurring in the therapeutic course and the relapse rate after treatment were observed as well.

RESULTSThe cure-obvious effective rate was 76.32% in the test group and 42.50% in the control group; the total effective rate in them was 94.74% and 77.50% respectively, all showing significant difference (P < 0.05) between groups. In the test group, slight diarrhea appeared in 5 patients and slight nausea with upper abdominal discomfort in 3; while in the control group, slight somnolence appeared in 2, but all these adverse reactions did not affect the treatment. A 3-month follow-up study showed that the relapse rate in the test group was significantly lower than that in the control group (16.00% vs. 42.50% , P < 0.01).

CONCLUSIONSLD is effective and safe in treating HDD, with the efficacy better and relapse rate lower than those of treatment with Western medicine alone.

SARS-CoV is a newly discovery pathogen causing severe acute respiratory problems.It has been established that the S protein in this pathogen plays an important rule in the adsorption and penetration of SARS-CoV into the host cell by interaction with the ACE2 receptor.To determinant which functional motif of the S protein was involved in the interaction with ACE2,seven truncated S proteins deleted from the N or C terminal were obtained by an E.coli expression system and purified by column chromatography to homogeneity.Each truncated S protein was fixed on to the well of an ELISA plate and an interaction was initiated with the ACE2 protein.The adsorption were quantified by ELISA,and the results indicated that amino acids from 388 to 496 of the S protein was responsible for the interaction with the ACE2 receptor,and the interaction could be completely disrupted by an antibody specific to these amino acids.Deletions adjacent to this domain did not appear to have a significant impact on the interaction with ACE2,suggesting that the S protein of SARS-CoV could be developed as a vaccine to prevent the spread of SARS-CoV.

OBJECTIVE: To observe the biological behavior of canine bone marrow stromal cells (BMSCs) cultured in vitro with the astragalus polysaccharides-chitosan/polylactic acid (AP-C/PLA) and with the chitosan/polylactic acid (C/PLA) and to find a suitable compound material for periodontal tissue engineering. METHODS: BMSCs (induced 14 days by 50 mg/L vitamine C, 10(-8) mol/L dexamethasone, 10 mmol/L beta-sodium glycerylphosphate) were cultured on AP-C/PLA or C/PLA for 5 days respectively. The BMSCs attachment and the morphology were observed with scanning electronic microscope and the combining rates were counted. Type I collagen synthesis was examined with immunohistochemistry staining and the content of osteocalin was determined with radio-immunological method. RESULTS: Combining rates, type I collagen synthesis, and the content of osteocalin of BMSCs on AP-C/PLA were significantly higher than those on C/PLA. CONCLUSION AP-C/PLA may promote the BMSC proliferation, differentiation and extracellular matrix synthesis, and it can be used as a good scaffold material for bone tissue engineering.
