OBJECTIVE: To evaluate clinical effect of unilateral approach and bilateral decompression via large channel endoscopic system for the treatment of lumbar spinal stenosis. METHODS: The clinical data of 32 patients with lumbar spinal tenosis treated by unilateral approach and bilateral decompression via large channel endoscopy from February 2018 to February 2019 were retrospectively analyzed. There were 18 males and 14 females, aged 65 to 84 years old with an average of (70.6± 8.4) years. The course of disease was from 1 to 12 years. All 32 cases were accompanied by numbness or pain in the lower limbs, of which 28 cases were accompanied by intermittent claudication. Narrow segments were L RESULTS: All the patients were followed up for 12-24 (17.68±2.43) months and all operations were successfully completed with the operation time of 70-160(85.64±11.94) min. Spinal dural tear occurred in 1 case during the operation, and sensory disturbance in the other side of lower limb in a short period of time occurred in 2 cases, all improved after corresponding treatment. Postoperative imaging showed that the spinal canal was significantly enlarged and the nerve root was fully released. Before operation and 3 days, 3 months, 1 year after operation, VAS scores of low back pain were 4.62 ±1.41, 2.73 ±1.35, 1.21 ±1.17, 1.11 ±0.34, respectively;VAS scores of leg pain were 6.83 ± 1.71, 3.10±1.50, 1.08±0.19, 0.89±0.24, respectively. VAS scores of low back pain and leg pain each time point after operation were obvious improved ( CONCLUSION It is a safe and effective way to treat lumbar spinal stenosis with unilateral approach and bilateral decompression via large channel endoscopic system. It has the advantages of sufficient decompression, less trauma, fast recovery, high safety and low incidence of postoperative complications. It can minimize the damage to the stable structure of the lumbar spine and is an ideal minimally invasive operation for the treatment of lumbar spinal stenosis.

Objective To compare the short-term therapeutic effects of the caudal-to-crainal and medial-to-lateral approaches for laparoscopic right hemicolectomy. Method The clinical data of 124 patients underwent laparoscopic right hemicolectomy in the department of gastrointestinal surgery, the First Affiliated Hospital of Kunming Medical Universitiy from,June 2014 to June 2016,were analyzed retrospectively. According the surgical operation, the patients were divided into two groups,caudal-to-crainal group with 48 patients,and medial-to-lateral group with 76 patients. The characteristics, opertation time, volum of blood loss during operation, the number of lymph node dissection, the rate of conversion to laparotomy,postoperative eating time, postoperative ventilation time, postoperative hospital stay time, postoperative complications of the two groups were analyzed to compare the short-term therapeutic effects. Result No significant differences were found in the sexual distinction, age, BMI,the volume blood loss during the operation, the number of lymph node dissection, the rate of conversion to laparotomy, postoperative eating time, postoperative ventilation time, postoperative hospital stay time, postoperative complications between the two groups (P＞0.05).Significant differences were found in the operation time [caudal-to-crainal group vs medial-to-lateral group (123.49 ±14.19 min VS 140.57 ±25.40 min) ] and the blood loss of the operation [caudal-to-crainal group vs medial-to-lateral group (60.63±24.00 ml vs 77.24 ±36.90 ml) ]. Conclusion The caudal-to-crainal approach for laparoscopic right hemicolectomy is more simple, practicable, with less blood loss during the operation and safer, which worth being recommended in right-hemicolectom-surgery.

To establish a method for the determination of three volatile components: menthone, menthol and pulegone in Yinqiao powder (YQP) decoction, explore the change rules of volatile components in decocting process, and provide evidence for elucidating the scientific connotation of its traditional decocting method "taking when the fragrance is volatilized fiercely". YQP decoctions with different decocting time were prepared, and GC-MS was used to qualitatively analyze the volatile components and determine the contents of menthone, menthol and pulegone in decoctions. Then the effects of different decocting time on contents of volatile components were investigated. The results showed that the volatile components in YQP decoctions mainly come from Menthae Haplocalycis Herba, Schizonepetae Herba and Forsythiae Fructus. With the extension of decocting time, the concentrations of all the above 3 volatile components in Yinqiao powder decoction were first increased and then decreased. When soaking for 30 minutes, as well as boiling for 0, 5, 10, 15, 20, 30, 40, 50, 60 minutes, the concentrations of menthone in YQP decoction were 0.058, 0.268, 0.216, 0.073, 0.065, 0.048, 0.048, 0.041, 0.038, 0.034 mg•L ⁻¹; the concentrations of menthol were 0.965, 2.847, 3.633, 2.420, 1.539, 1.189, 1.273, 1.188, 0.905, 0.663 mg•L ⁻¹; the concentrations of pulegone were 0.355, 0.522, 0.598, 0.477, 0.374, 0.374, 0.339, 0.355, 0.248, 0.251 mg•L ⁻¹; and the total concentrations were 1.377, 3.637, 4.446, 2.970, 1.979, 1.611, 1.660, 1.583, 1.191, 0.947 mg•L ⁻¹, respectively. The results showed that the contents of menthone, menthol and pulegone in YQP decoctions were heavily influenced by the decocting time. The fragrance was volatilized fiercely at about 5 minutes after boiling, with larger concentrations of the above three volatile components in decoction; the fragrance got weak after 15 minutes of boiling, the concentrations of menthone, menthol and pulegone in YQP decoctions were significantly decreased, indicating that the traditional decocting method "taking when the fragrance is volatilized fiercely" has some scientific foundation.

OBJECTIVETo investigate the association between TaqI, BsmI, and ApaI polymorphisms of vitamin D receptor (VDR) gene and pediatric Crohn's disease (CD) in China.

METHODSNineteen children with CD were selected as a case group, and 122 healthy children who underwent physical examination were selected as a control group. Serum 25-hydroxyvitamin D3 [25(OH)D3] levels were measured using ELISA. The TaqI, BsmI, and ApaI polymorphisms of VDR gene were determined by gene sequencing, and the two groups were compared in terms of genotype and allele frequencies.

RESULTSThe case group had significantly lower serum 25(OH)D3 levels than the control group (17.3±2.4 ng/mL vs 26.9±2.1 ng/mL; P<0.05). There were no significant differences in the frequencies of genotypes and alleles of TaqI, BsmI, and ApaI polymorphisms between the case and control groups (P>0.05).

CONCLUSIONSChildren with CD have low serum 25(OH)D3 levels. TaqI, BsmI, and ApaI polymorphisms of VDR gene may not be associated with susceptibility to CD among the Chinese population.

BACKGROUNDA multi-center large scale study is needed to confirm the efficacy and safety of domestic peritoneal dialysis (PD) solutions. Some researchers believe that 6 L/d is enough for adequate dialysis, but there is no multi-center prospective study on Chinese population to confirm this. In this study, we evaluated the efficacy and safety of domestic PD solution (Changfu) and its difference between 6 L and 8 L dosage.

METHODSAdult PD patients who had taken PD therapy for at least one month were selected and divided into four groups according to two dialysis solution brands and two dialysis dosages, i.e., 6 L dose with Changfu dialysis solution, 6 L dose with Baxter dialysis solution, 8 L dose with Changfu dialysis solution, and 8 L dose with Baxter dialysis solution. After 48 weeks, the changes of primary and secondary efficacy indices were compared between different types and different dosages. We also analyzed the changes of safety indices.

RESULTSChanges of Kt/V from baseline to 48 weeks between Changfu and Baxter showed no statistical differences; so did those of creatinine clearance rate (Ccr). Normalized protein catabolic rate (nPCR) from baseline to 48 weeks between Changfu and Baxter showed no statistical differences; so did those of net ultrafiltration volume (nUF) and estimated glomerular filtration rate (eGFR). Changes of nPCR from baseline to 48 weeks between 6 L and 8 L showed no statistical differences; so did those of nUF and eGFR. The decline of Kt/V from baseline to 48 weeks in 6 L group was more than that in 8 L group. Change of Ccr was similar. During the 48-week period, the mean Kt/V was above 1.7/w, and mean Ccr was above 50 L×1.73 m(-2)×w(-1). More adverse events were found in Changfu group before Changfu Corporation commenced technology optimization, and the statistical differences disappeared after that.

CONCLUSIONSThe domestic PD solution (Changfu) was proven to be as effective as Baxter dialysis solution. During 48-week period, a dosage of 6 L/d was enough for these patients to reach adequate PD. Clinical study promotes technological optimization, further helps to improve the safety indices of the medical products.

OBJECTIVETo investigate the changes in the numbers of blood vessels and mast cells, which is relative to blood microcirculation in skin, during Qingpeng plaster (ZANG medicine) being applied to the skin surface of nude mice.

METHODFifteen healthy adult nude mice were divided into Qingpeng plaster group and the control group. The sites of skin tissues stuck with the plaster or with control plaster were selected after 7 days treated, and then all the slices stained and observed.

RESULTThe numbers of the vessels and the mast cells increased in the dermal tissue of Qingpeng paster group. Although there were a few dilated blood vessels in the control group, but the numbers of the vessels and the mast cells were obviously less than those of the Qingpeng plaster group. Statistical analysis showed that there was a significant difference (P < 0.001) between tow groups.

CONCLUSIONQingpeng plaster can cause obvious vascular dilatation and promot mast cells aggregation in the Qingpeng plaster stuck parts of the skin tissue.

For epidemiological investigation of the rabies virus carrier rates of domestic dogs, cats and wild animals like rodent animals and bats,three kinds of regions where rabies had higher incidence (Hunan and Guizhou Provinces), lower incidence (Jiangsu Province, Wuhan City) and provisionally rabies-free (Shenyang City) were selected. Then the antigenic types, the genovariation of the isolaled viruses and the currently vaccine matching of the virus strains were analyzed. The results showed that in China the principal host of rabies is dog,the total virus carrier rate of the captured dogs was 2.56%, and the highest positive isolation rate was 20.0% in some monitoring site. However,there was no evidence about the rabies virus carrier rate in rodent animals,bats or other wild animals. The rabies vaccines which prepared from aG and CTN strains have already been produced successfully in China. The research showed that the nucleotide sequences of the newly isolated viruses were more similar with the glycoprotein gene of CTN strain. In order to evaluate the safety and the efficacy of the vaccines currently used, two groups (50 people each) were injected with vaccine of aG strain and CTN strain respectively in five surveillance points. The neutralizing antibody tested were 0.49 IU/mL-0.52 IU/mL and 6.7 IU/mL-7.53 IU/mL after the 7 and the 14 days of vaccine injection respectively. In addition, the rates of antibody positive seroconversion were 45.1%-47.9% and 100% respectively, and there was no moderate or severe adverse reactions observed. These data showed the vaccines have satisfactory effect on safety and protection.

OBJECTIVETo study the rabies molecular biology features in animals between high incidence area of rabies and no rabies cases area in Hunan.

METHODSdetect saliva of dogs and brains of dogs and cats by direct immunofluorescence assay, review positive samples by RT-PCR, sequencing extract RNA virus for genetic analysis.

RESULTS12 were detected rabies virus antigen and positive nucleoside acid in 82 dogs from Wugang city also 1 in 17 from Dongkou county; the positive rate: Wugang 14.63 percent, Dongkou 5.88 percent. No rabies virus was detected in 67 samples of dog brains from Fenghuang County. Also none in 28 samples of cat brains. Amplificating N gene of rabies virus from positive samples of dog brain's tissue (No Wg13, Dk13) by RT-PCR, it shows that homology of nucleoside acid between two strain of virus is 99.4 percent; also 99.1 percent of amino acid. The homology of nucleoside acid (amonio acid) among Wg13 stain and Chinese strain CTN and aG strain is 89.4 percent (98.2 percent) and 86.1 percent (95.1 percent); The homology of nucleoside acid (amonio acid) among Dk13 stain Chinese strain CTN and aG strain is 89.1 percent (98.0 percent), 86.1 percent (94.9 percent).Compare with isolated rabies virus from abroad, the homology between two strains and Indonesia is 92.8 percent and 93.2 percent, the most similar of them. The strains isolated from other countries including Japan, Sri Lanka and India are relatively lower; The sequence of gene Wg13 and Dk13 were taken replacement of amino acid.

CONCLUSIONTwo strains are belong to type I rabies virus, comparing its N gene with current using vaccine strains, both are in same group, and homology are relatively higher.

OBJECTIVETo evaluate the effectiveness and safety of sirolimus-eluting stents (SESs) for treatment of in-stent restenosis (ISR).

METHODSAll 27 patients with ISR and clinical evidence of ischemia had been treated with SESs. Among them, 23 patients had diffuse and complex lesions, and 5 of them received 2 SESs. Clinical and angiographic follow-up were performed for all patients and the results were analyzed.

RESULTSAll stents were implanted successfully. There were no remained stenosis and major in-hospital complications. Average follow-up time was 8.9 +/- 2.1 (5-14) months, with a clinical follow-up rate of 96.3% and angiographic follow-up rate of 92.6%. During the follow-up, there was none of death. One patient had recurrent angina with an angiographic evidence of the proximal edge restenosis of the stent. Mild neointimal hyperplasia in the proximal edge was found in 2 patients, but the stenosis was less than 25%. No late lumen loss was found in other 24 patients. The late lumen loss of the in-stent averaged 0.09 +/- 0.02 mm, and of the distal edge vessel averaged 0.10 +/- 0.03 mm, and of the proximal edge vessel averaged 0.20 +/- 0.06 mm. The rate of target vessel revascularization was 3.8%.

CONCLUSIONThe SES implantation is safe and feasible for the treatment of in-stent restenosis, which could effectively prevent neointimal hyperplasia and recurrent restenosis of the lesion.
