By using 5'-nucleotidase-alkaline phosphatase (5'-Nase-AlPase) double staining method, the fine distribution of the lymph vessels in the stomach wall of the rabbit, guinea pig and rat has been observed. Under light microscope lymph capillaries showed strongly 5'-Nase positive reaction with brown or dark brown staining. However blood capillaries revealed significantly A1Pase activity with blue staining. The lymph capillaries were seen in all layers of the stomach wall in three species, but the lymph vessels were only shown in the submucosa, muscularis and serosa. In the mucosa lymph capillaries could be found in the deep layer of the lamina propria. In the submucosa there were lymph vessels and capillaries. In the muscularis lymph capillaries and vessels not only could be found between oblique and circular muscle or between circular and longitudinal muscle, but also among muscle fiber bundles of each layer. In the serosa there were larger lymph vessels situated near the muscularis. The observation on semithin and ultrathin sections also shown the similarity in the lymph vessels distribution. There was no difference in the distribution of lymph vessels in the stomach wall between rabbit, guinea pig and rat.

OBJECTIVETo lay a foundation for the study on good variety selection of Isatis indigotica, comparison of plant traits and quality evaluation of Isatis germplasm resources from different production area was conducted.

METHODField cultivation and randomized block experiment were adopted to compare those plant traits of leaf, root, silique and seed of Isatis from different production area and the content of R,S-goitrin and polysaccharide in the root was determined.

RESULTDifferent cultivation forms of Isatis had significant difference from each other in leaf, root, silique and seed, content of R,S-goitrin and polysaccharide in the root were also different. R,S-goitrin content in Isatis of Chinese cabbage leaf type ( production area: Yunnan ) was comparative higher, 0.59% , while polysaccharide content in autotetraploid Isatis was comparative higher, 8.68%.

CONCLUSIONAccording to the plant traits, Isatis were classified into three types: Chinese cabbage leaf type, cabbage leaf type and mustard leaf type, of which R,S-goitrin content in Chinese cabbage leaf type (production area: Yunnan) was comparative higher, while polysaccharide content in autotetraploid Isatis was comparative higher.

OBJECTIVETo discuss the methods for urethral external meatus and glanuloplasty after correction of hypospadias.

METHODSThe V shape flap on the dorsal side of glan, combined with the bilateral glan flaps were moved to the ventral side. The flap at the ventral side of urethral external meatus was turned over. Then the urethral external meatus was repositioned to the top end of glan with the ventral defects covered by the dorsal flaps. Then the coniform glan was reconstructed.

RESULTSFrom January 2008 to December 2013, 28 cases were treated, including glandular hypospadias, postoperative retraction of external urethral meatus and meatal stenosis. 21 patients were followed up for 1 -12 months (average, 1 month) with marked improvement of glan appearance and retraction of external meatus. No meatal stenosis happened.

CONCLUSIONSPostoperative retraction of urethral external meatus and meatal stenosis can be corrected by V shape flap on the dorsal side of glan combined with the bilateral glan flaps. The flat appearance of glan can be improved. It is an ideal method for glandular hypospadias.

Objective To investigate the application of the repeated expanded bilateral deltopectoral flap for resurfacing severe facial cervical scar, with review of relating articles to discuss issue of repeated expanding flap.Methods Nine patients suffered from hyperplastic facial and cervical scar.Two soft tissue expanders were implanted into the anterior chest region at both sides of sternum.The center of inner border of the expander was at the cross of second intercostal and parasternal line, and the lengthways axe of the expander was located at the ligature of the second intercostals and mammary areola.After two weeks when the expander was filled, expanded flap was transferred to cervical defect.The transferred flap was repeated expanded after half a year and transferred to resurface facial defect.Results In the first expansion stage, 600 or 800 ml expander were implanted in each side of sternum.In the second stage, 400 or 500 ml were used.The first stage of expanding process was smooth, and 2 of the expanding flaps were ruptured during the second expansion period.400-520 cm2 (average 440 cm2) additional expanded flap was acquired during two stages of expanding.Conclusions The repeated expanded bilateral deltopectoral flap gives us greater opportunity to repair severe facial-cervical scar.The best interval time of the two-stage expansion is over half a year.The speed of second expansion should be lower than that in the first stage, and protecting the expanding flap carefully from external force compression is needed during the second expasion.

Objective:To compare the effects of pressure controlled ventilation (PCV) and volume controlled ventilation (VCV) on respiratory mechanics, hemodynamics and biochemical metabolism in patients undergoing laparoscopic colorectal cancer surgery.Methods:The clinical data of 78 patients underwent laparoscopic colorectal cancer surgery from August 2019 to June 2020 in Inner Mongolia People′s Hospital were retrospectively analyzed. Among them, 39 patients were treated with PCV (PCV group), and 39 were treated with VCV (VCV group). The respiratory mechanics, hemodynamics and biochemical metabolism indexes 10 min after anesthesia induction (T 1), 10 min after pneumoperitoneum + low head and foot height (T 2), 60 min after pneumoperitoneum + low head and foot height (T 3) and 120 min after pneumoperitoneum + low head and foot height (T 4) were recorded. The respiratory mechanical indexes included mean airway pressure (P mean), airway peak pressure (P peak), pressure of end tidal carbon dioxide (P ETCO 2) and dynamic lung compliance (C Ldyn); hemodynamic indexes included mean arterial pressure (MAP) and heart rate; and biochemical metabolic indexes included base excess, serum natrium, serum potassium, negative logarithm of the hydrogen ion concentration (pH) and blood glucose. Results:The P mean, P peak and P ETCO 2 T 1 to T 4 in PCV group were significantly lower than those in VCV group, P mean: (7.12 ± 1.37) cmH 2O (1 cmH 2O = 0.098 kPa) vs. (8.54 ± 1.84) cmH 2O, (9.80 ± 2.26) cmH 2O vs. (11.63 ± 2.87) cmH 2O, (9.51 ± 2.17) cmH 2O vs. (11.72 ± 2.90) cmH 2O, (7.04 ± 1.34) cmH 2O vs. (8.65 ± 1.88) cmH 2O; P peak: (13.41 ± 2.68) cmH 2O vs. (15.06 ± 3.05) cmH 2O, (20.92 ± 3.11) cmH 2O vs. (23.45 ± 4.02) cmH 2O, (21.14 ± 3.50) cmH 2O vs. (23.69 ± 4.26) cmH 2O, (15.03 ± 2.74) cmH 2O vs. (16.45 ± 3.21) cmH 2O; P ETCO 2: (30.59 ± 1.57) mmHg (1 mmHg = 0.133 kPa) vs. (32.04 ± 2.11) mmHg, (35.02 ± 4.15) mmHg vs. (39.88 ± 4.76) mmHg, (35.90 ± 4.22) mmHg vs. (40.11 ± 4.87) mmHg, (34.33 ± 4.17) mmHg vs. (37.65 ± 2.69) mmHg; the C Ldyn was significantly higher than that in VCV group: (40.68 ± 3.98) ml/cmH 2O vs. (35.47 ± 2.56) ml/cmH 2O, (30.25 ± 3.21) ml/cmH 2O vs. (22.40 ± 2.75) ml/cmH 2O, (29.78 ± 3.06) ml/cmH 2O vs. (22.60 ± 2.81) ml/cmH 2O, (40.32 ± 4.25) ml/cmH 2O vs. (33.61 ± 2.81) ml/cmH 2O, and there were statistical differences ( P<0.01 or <0.05). The MAP and heart rate T 1 to T 4 in PCV group were significantly lower than those in VCV group, and there was statistical difference ( P<0.01 or <0.05). The base excess, serum natrium, serum potassium and pH T 1 to T 4 in PCV group were significantly higher than those in VCV group, while the blood glucose was significantly lower than that in VCV group, and there was statistical difference ( P<0.01 or <0.05). Conclusions:Compared with VCV, PCV can promote the recovery of respiratory mechanics index, stabilize hemodynamics and improve biochemical metabolism index in patients undergoing laparoscopic colorectal cancer surgery.

OBJECTIVETo investigate the application of pedicled expanded flaps for the reconstruction of facial soft tissue defects.

METHODSThe expanded skin flaps, pedicled with orbicularis oculi muscle, submental artery, the branch of facial artery, superficial temporal artery, interior upper arm artery, had similar texture and color as facial soft tissue. The pedicled expanded flaps have repaired the facial soft tissue defects.

RESULTSBetween Jan. 2003 to Dec. 2013, 157 cases with facial soft tissue defects were reconstructed by pedicled expanded flaps. Epidermal necrosis happened at the distal end of 8 expanded flaps, pedicled with interior upper arm artery(4 cases), orbicularis oculi muscle(3 cases) and submental artery(1 case), which healed spontaneously after dressing. All the other flaps survived completely with similar color and inconspicuous scar. 112 cases were followed up for 8 months to 8 years. Satisfactory results were achieved in 75 cases. 37 cases with hypertrophic scar at incisions need secondary operation.

CONCLUSIONSIsland pedicled expanded flap with similar texture and color as facial soft tissue is suitable for facial soft tissue defects. The facial extra-incision and large dog-ear deformity could be avoided.
