Objective To explore the safe technique of caudate lobectomy for liver cancer in candafe lobe(LCCL).Methods The clinical data of 11 cases of primary liver cancer in caudate lobe who received hepatectomy successfully were retrospectively analyzed. four procedures were used in the operations:(1)selection of appropriate skin incision, so as to obtain excellent exposure of operative field;(2)adequate mobilization of the liver to allow the liver to be displaced upwards to the left or to the right;(3)preparatory placement of tapes for total hepatic vascular isolation,so that this procedure can be used when necessary;(4)selection of the ideal route for hepatectomy based on the condition of the tumor and, if necessary, the combined removal of multiple lobes. Among the 11 cases, simple occlusion of vessels of porta hepatis was used for candate lobectomy in 6 cases, while, in the other cases, the vessels were intermittently occluded several times or total hepatic vlascular isolation was used for the caudate lobectomy. combined partial right hepatectomy was done in 2 cases, combined left lateral lobectomy in 3 cases and caudate lobectomy alone in 6 cases.Results Operation was smooth and successful in all of the 11 cases, and there was no mortality. Conclusions Caudate lobectomy for LCCL can be safely performed when the above procedures are used.

Objective:To investigate the effect of pelvic motion in late pregnancy on the outcome of first trimester delivery.Methods:A total of 127 first-borns admitted to the midwifical clinic of Nanjing Maternal and Child Health Hospital from November 1, 2019 to March 10, 2020 were selected as the research objects, and they were divided into the walking group and the pelvic motion group according to the random number table method. In the end, 62 cases were included in the walking group and 65 cases in the pelvic motion group. The walking group did brisk walking in the third trimester. In the pelvic motion group, the motion in the third trimester consisted of the combined pelvic motion involving the two planes of the upright spine and the horizontal spine, and multiple peripelvic joints. The changes of fertility, birth canal and fetus before and after exercise were observed, and the outcomes of childbirth were compared between the two groups.Results:Indicators reflecting productivity: persistence time of "air bike" on the day before delivery was (27.12±7.73) seconds in the pelvic motion group and (20.56±6.60) seconds in the walking group, the difference was statistically significant ( t value was 5.12, P<0.01). The time of contractions after exercise before delivery was (269.38±123.70) seconds in the pelvic motion group and (591.29±201.82) seconds in the walking group, the difference was statistically significant ( t value was 10.89, P<0.01). The indicators reflecting the situation of the maternal birth canal were as follows: "sitting forward flexion level", pelvic motion group was (33.64±5.91) cm, walking group was (29.50±5.28) cm, the difference was statistically significant ( t value was 4.15, P<0.01). The cervical score during regular contractions was 8.01±1.69 in the pelvic motion group and 7.30±1.40 in the walking group, the difference was statistically significant( t value was 2.56, P<0.05). At the beginning of regular contractions, the proportion of fetal "occipital position" was 93.85% (61/65) in the pelvic motion group and 72.58%(45/62) in the walking group, the difference was statistically significant ( χ2 value was 10.41, P<0.01). The "no pain rate after exercise the day before delivery" was 72.31% (47/65) in the pelvic motion group and 29.03% (18/62) in the walking group, the difference was statistically significant ( χ2 value was 25.30, P<0.01). Time of the first labor was (395.84±165.24) min in the pelvic motion group and (574.35±152.23) min in the walking group, the difference was statistically significant ( t value was 6.32, P<0.01). The second stage of labor was (25.98±9.88) min in the pelvic motion group and (33.62±13.94) min in the walking group, the difference was statistically significant ( t value was 3.57, P<0.01). Conclusions:Pelvic motion in middle and late pregnancy can affect labor force, birth canal, fetus and other delivery factors, reduce movement pain and shorten the time of labor.
