A cutaneous branch of the suprascapular nerve was observed in 9 from 180 Chinese adult arms (5.0?1.62%), it has been found bilaterally in 3, and unilaterally in other 3 male cadavers.The cutaneous branch arose from the stem of an essentially normal suprascapular nerve under the superior transverse scapular ligament. After passing between the coraco-clavicular and coraco-acromial ligaments the cutaneous branch pierced obliquely the deltoid muscle and supplied the proximal third of the antero-lateral aspect of the arm. The distribution territory of the cutaneous branch coincided with the anterior half of the deltoid muscle.

Objective To simulate the solution drought stress conditions with polyethylene glycol (PEG) 6000 for study on the seed germination of Cassia occidentalis.Methods The seed of C.occidentalis was treated with 5% and 10% PEG 6000,respectively,then the germination rate,the activity of superoxide dismutase (SOD),peroxidase (POD),and content of malondialdehyde (MDA) were measured.Results Compared with the same period of the control,soaking with 5% PEG 6000 for 5 h could increase the activity of SOD and POD,decrease the content of MDA.PEG Pretreatment could decrease free radical accumulation and make cell membrane system less damaged in the course of absorbing water in seed.Conclusion Soaking with 5% PEG 6000 for 5 h could increase the seed germination rate of C.occidentalis.

Objective:To investigate the masticatory function and the expression of monocyte chemoattractant protein-1 (MCP-1) and tumor necrosis factor-α(TNF-α) in gingival crevicular fluid.Methods:The clinical data of 98 patients with dentition loss admitted to Tongxiang First People′s Hospital from June 2017 to June 2019 were analyzed, and 49 cases were treated with oral implant repair(observation group) and 49 cases were treated with conventional repair(control group). Both groups were followed up for 6 months. The masticatory function, speech function, retention function, quality of life and the changes of MCP-1 and TNF-α in gingival crevicular fluid were compared before treatment and 6 months after treatment.Results:The total effective rate of the observation group was higher than that of the control group: 95.92%(47/49) vs. 79.59%(39/49), and the difference was statistically significant ( χ2=6.078, P<0.05). At 6 months after treatment, the scores of masticatory function, speech function and retention function in the observation group were higher than those in the control group ( P<0.05). The scores of emotional function, social function and physiological function in the observation group were higher than those in the control group ( P<0.05). The levels of MCP-1 and TNF-α in gingival crevicular fluid of the observation group were lower than those of the control group: (32.09 ± 7.65) μg/L vs. (43.62 ± 9.23) μg/L, (2.19 ± 0.38) μg/L vs. (3.20 ± 0.51) μg/L, and the differences were statistically significant ( P<0.05). Conclusions:Dental implant repair is effective for patients with dentition loss, and it can improve masticatory function and quality of life, and reduce the expression of MCP-1 and TNF-α in gingival crevicular fluid.

The branches of the a. iliaca int. and ext. of 60 Chinese male adult cadavers (120sides) were studied and the findings are as follows: 1. The average length of the internal iliac trunk is 4.35?0.17cm,?=?1.34cm,in the left, and 4.56?0.21cm,?=?1.63 cm in the right. It is inversely proportionalto the average length of the common iliac artery. 2. The patterns of the branching of the superior, inferior gluteal and internalpudendal artieries may be classified into 5 types: type Ⅰ is present in 63 sides (cases)(52.5?4.55%); type Ⅱ and Ⅲ occur in 26 cases (21.67?3.76%); type Ⅳ occursin 4 cases (3.33?1.64%) and type Ⅴ is present only in 1 side (0.85 0.83%). 3. In most of the cases, the superior gluteal artery passes between the lumbosacraltrunk and the first sacral nerve (79.83%), while the inferior gluteal (66.67%) and theinternal pudendal artery (62.19%) usually pass between the second and third sacralnerve into the gluteal region. A few of these vessels may divide into 2 or 3 branchesbefore leaving the pelvis. 4. The accessory pudendal artery is present in 13 cases (10.83?2.83%). 5. The obturator artery originates from the internal iliac artery in 102 cases(85.0?3.26%), most of them spring from the anterior trunk of the internal iliacartery. In the other 18 cases, 2 spring directly from the external iliac artery (1.67?1.17%), 13 from the inferior epigastric artery (10.83?2.85%), and 3 have doubleorigins (2.5?1.42%), in which the 2 branches spring separately from the internal iliacand inferior epigastric artery. These abnormal obturator arteries occur in 14 cadavers(23.33?5.44%). 6. The iliolumbar artery is present in 80 cases (66.67?4.30%) as a singlebranch, in 37 cases (30.83?4.2%) with 2 separate branches and in 3 cases (2.5?1.43%) with 3 branches. It has various origins, most of them spring from the maintrunk or from the posterior trunk of the internal iliac artery. 7. The lateral sacral artery occurs in 54 cases (45.0?4.54%) as a single branch,in 57 cases (47.5?4.55%) with 2 branches, and in 9 cases (7.5?2.44%) with 3branches. Its origin is comparatively constant, usually arising from the posterior trunkof the internal iliac artery. 8. Most of the superior vesical arteries spring from the root of the umbilical artery.The number of branches of this vessel varies from 1 to 6, but most of them have 1 (46cases, 38.33?4.43%) or 2 (45 cases, 37.5?4.42%) branches. 9. The inferior vesical artery has 1--3 branches. Most of them have a singlebranch (104 cases, 86.67?3.1%), it springs commonly from the anterior trunk of theinternal iliac artery or from the internal pudendal artery. 10. The deferent artery springs in 85 cases (70.83?4.15%) as a single branch,and in 35 (29.17?4.15%) with 2 branches. In the single-branch type it springsmostly from the root of the umbilical artery, and in the two-branch type both springcommonly from the superior vesical artery. 11. The inferior rectal (middle hemorrhoidal) artery is present only in 106 cases(88.33?2.93%), most of them spring from the internal pudendal and inferior glutealarteries. In 3 cadavers (5.0?1.99%) they spring from the middle sacral artery sym-metrically. 12. In 103 cases (85.85?3.32%) the inferior epigastric artery springs indepen-dently from the external iliac artery, in 16 cases (13.33?3.13%) it springs as a com-mon trunk with the obturator artery, and in one side (0.83?0.83%) with the medialfemoral circumflex artery. Its origin-site on the external iliac artery is proxmal to theinguinal ligament in 69 cases (57.5?4.51%) with an average distance of 0.95?0.10cm,?=?0.59cm in the left, and 0.73?0.08 cm,?=?0.43 cm in the right; in 43cases (35.83?4.67%) the origin-site is just behind the ligament; and in 8 cases(6.67?2.28%) it is distal to the ligament, its average distance is 0.48?0.09 cm,?=?0.18 cm in the left, and 0.45?0.11 cm,?=?0.22 cm in the right. 13. The deep iliac circumflex artery, a single branch, is present in 115 cases(95.83?1.82%), the remaining 5 cases (4.17?1.82%) have 2 branches. In 54cases (45.0?4.54%) its origin-site is just behind the inguinal ligament; in 36 cases(30.0?4.18%) is proximal to the ligament with an average distance of 0.56?0.09cm,?=?0.38 cm in the left, and 0.61?0.09 cm,?=?0.35 cm in the right; and in25 cases (20.83?3.72%) it is distal to the ligament, the average distance shows0.62?0.12 cm,?=?0.45 cm in the left, and 0.69?0.12 cm,?=?0.41 cm in theright.

Objective:To study the coronal bone structure matching of distal radius in normal population and some patients with postoperative distal radius fracture, and to explore the clinical significance of coronal bone structure reduction of distal radius fracture.Methods:CT scans of 80 asymptomatic wrists were performed. Mimics 20.0 and 3-Matic research software were used to measure the matching data of coronal bone structure of the distal radius. Total of 44 patients with distal radius fractures treated with open reduction and volar plate fixation were collected. According to the data coronal bone structure of the distal radius, the matching group was in the normal range, and the mismatching group was less than the normal range. X-ray films were used to evaluate fracture healing, humeral height, ulnar angle and palm tilt angle at 3 months and 12 months after operation. The clinical indexes of wrist pain, wrist function, grip strength and activity were recorded in 2 groups. The DASH score was used for evaluation, and statistical comparisons was made between the two groups of related indicators.Results:The coronal bone structure matching value of the distal radius in 80 normal adults was 45.0%±16.2%. All the 44 patients with distal radius fracture were followed up for an average of 16 months. The postoperative wound healing was good, and the bone healing standard was reached 3 months after the operation. 3 months after surgery, radius height, ulnar deviation angle and palmar inclination angle of the mismatched group were all smaller than those of the matched group, but the differences had no statistical significance. The pronation angle in the mismatched group (68.82°±11.62°) was lower than that in the matched group (76.91°±9.14°), and the difference was statistically significant ( t=2.567, P=0.014). The DASH score in the mismatched group (15.53±2.36) was higher than that in the matched group (13.62±2.52), and the difference was statistically significant ( t=2.591, P=0.013). 12 months after surgery, the VAS score of the matched group (2.08±2.95) was less than that of the mismatched group (2.95±1.24), and the difference was statistically significant ( t=2.348, P=0.024). There was no significant difference in wrist range of motion, grip strength and DASH score between the two groups. Conclusion:The coronal bone structure matching of distal radius is about 45.0% in normal population. Early wrist dysfunction, limited pronation, and wrist pain may occur when the postoperative matching degree of the distal radius fracture is not within the normal range.
