1.Treatment of severe duodenal trauma
Chinese Journal of General Surgery 1993;0(03):-
Objective To study the operative method for severe duodenal trauma.Methods The clinical data of 38 cases of severe duodenal trauma complicated with pancreatic injury who underwent different operations between 1992—2006 year were reviewed.Results In 8 cases duodenal diverticulization was performed,of which 5 cases were cured,2 cases developed intestinal fistula,and one died.Of 9 cases who underwent panceaticoduodenectomy(PD),3 were cured but 6 had pancreatic leakage,and 3 of them died.Of 16 cases who had primary repair of ruptured duodenum with simple suture or patch suture,13 cases cured,2 cases developed intestinal fistula and one patient died.Five patients underwent duodenal repair and excision of head of pancreas plus pancreaticojejunostomy(PD with preserved duodenum),4 cases recovered and 1 had pancreatic leakage,but 3 with wrap-type pancreaticojejunostomy had no complications.Conclusions The repair of ruptured duodenum with simple suture plus duodenostomy and jejunostomy is preferential option for majority of cases of duodenal trauma.This procedure plus removal of head of pancreas and pancreaticojejunostomy(PD with preserved duodenum) can be used for severe pancreatic injury with excellent result,but duodenal diverticulization or panceaticoduodennectomy must not be undertaken lightly.

Objective To observe the effects of hyperbaric oxygen (HBO) on the expression of FasL mRNA and caspase-3 protein in renal tissue after renal ischemia-reperfusion injury (IRI) in order to elucidate the underlying mechanisms.Methods Rats were randomly divided into thrcc groups: sham group(n=8),IRI group(n=8) and IRI+HBO group(n=8).The IRI group and the IRI+HBO group recieved 45 minutes hibateral renal ischima and the IRI +HBO group received additional HBO therapy at the 1st,24th and 48th hour after ischemia.The kidneys were removed at the end of HBO therapy.Malondialdehyde (MDA) level and superoxide dismutase (SOD) activity were measured to determine the extent of oxidative stress.The expression of FasL mRNA and caspase-3 protein was detected by quantitative real-time PCR and immunohistochemical staining in renal tissue respectively.Results Compared with the sham group,MDA level increased markedly and SOD activity decreased markedly after ischemia.After HBO treatment,MDA level decreased and SOD activity increased significantly (P <0.05).In IRI group,the expression of FasL mRNA and caspase-3 protein were higher than those in the sham group (P<0.01),which were reduced significantly by HBO treatment (P<0.01).Conclusion The expression of FasL mRNA and caspase-3 protein increases along with the lasting of reperfusion and HBO exhibites protection against cell apoptosis through improving the antioxidant-oxidant balance and reducing IRI in acute stage of IRI.

Objective To investigate the relationship between serum progesterone level at the day with human chorionic gonadotrophin (hCG) administration and pregnant outcome from in in-vitro fertilization-embryo transfer(IVF-ET). Methods From Mar. 2002 to Apr. 2007, 786 cycles with serum progesterone measurement on the day of hCG administration for final oocyte maturation in IVF were analyzed retrospectively in Reproductive Medicine Center in First Affiliated Hospital of Nanjing Medical University.All stimulations were down-regulated with gronadotrophin release hormone agonist (GnRH-a) in both long protocols and short protocols before gonadotrophin stimulation. When the thresholds of serum progesterone were set at 5.5, 6.0,6.5,7.0,7.5,8.0,8.5 and 9.0 nmol/L, respectively. If the level of progesterone was less than the thresholds, those patients were in lower progesterone group, on the contrary, more than the threshold value, those patients were in higher progesterone group. The laboratory results and the clinical outcomes between all patients at lower and higher progesterone group at different thresholds value were analyzed. Results The rate of normal fertilization, quality embryos, successful implantation, chemical pregnancy, clinical pregnancy and live birth did not exhibit remarkable difference between patients with higher and lower serum progesterone level at multiple thresholds on the day of hCG administration in the 786 cycles (P >0.05). However, when the thresholds of serum progesterone were at 8.5 and 9.0 nmol/L, early abortion rates of 27.3% (3/11) and 3/7 in higher progesterone group were significantly higher than 8.8% (26/297) and 8.6% (26/301) in lower progesterone group (P<0.05). And the total abortion rates of 3/7 in higher progesterone group were significantly higher than 11.0% (34/301) in lower progesterone group when the thresholds of serum progesterone were 9.0 nmol/L (P<0.05). Conclusions This study did not prove the correlationship between progesterone level at the clay with hCG administration and the probability of clinical pregnancy or live birth. However, early abortion rates or the total abortion rates were associated with higher progesterone level when the thresholds of serum progesterone were at 8.5 nmol/L or 9.0 nmoL/L.

BACKGROUND:Atlantoaxial dislocation is often facilitated by interlaminar bone grafting.However,there are relatively few reports on the treatment of complex atlantoaxial dislocation with posterior atlantoaxial lateral mass interarticular release and fusion. OBJECTIVE:To explore the safety and effectiveness of atlantoaxial dislocation treated by simple posterior atlantoaxial lateral block interarticular release and fusion. METHODS:We retrospectively analyzed the clinical data of 30 patients with atlantoaxial dislocation who were treated from January 2017 to July 2021,all of whom suffered from reducible atlantoaxial dislocation.Posterior atlantoaxial lateral mass interarticular release and fusion were performed in all patients.During the surgery,patented instruments were used to release the atlantoaxial lateral mass joint,and posterior screw reduction and fixation were used with bone grafting in the lateral mass joint space.The postoperative follow-up period was 6 to 24 months,mean(13.0±5.4)months.During the follow-up period,cervical MRI was reviewed to observe the decompression of the upper cervical spine.X-ray films and CT scans were reviewed to observe the reduction of the upper cervical spine,as well as the internal fixation for looseness and breakage.CT scans were reviewed to assess interlateral block implant fusion.The Japanese Orthopaedic Association score was used to evaluate the improvement of spinal cord function.The neck disability index and the quality of life scale were used to assess the improvement of daily life function.The atlanto-anterior interspace and atlanto-planar spinal effective space were used to evaluate atlantoaxial repositioning and decompression. RESULTS AND CONCLUSION:(1)The surgery of 30 patients went smoothly,and no serious complications such as spinal nerve and vertebral artery injuries occurred during the operation.Postoperative review of cervical MRI showed that the spinal cord compression was lifted.X-ray film and CT showed that the atlanto-anterior gap was significantly reduced;the effective space of atlantoaxial spinal cord was significantly increased,and neurological dysfunctional symptoms were significantly reduced.(2)During the follow-up period,X-ray film and CT showed that the internal fixation was solid;no broken nails or rods occurred,and there was no recurrence of atlantoaxial dislocation.(3)The Japanese Orthopaedic Association scores,neck disability index,and quality of life scores were significantly improved at the last follow-up compared with the preoperative period(P<0.05).The average improvement rate of Japanese Orthopaedic Association scores at the last follow-up was 73.1%.The average neck disability index was 8.80%.All of the patients had a continuous bone-scalp connection between atlantoaxial lateral block joints to achieve osseous fusion.(4)These findings indicate that the use of simple posterior atlantoaxial lateral block interarticular release and fusion for the treatment of atlantoaxial dislocation can significantly increase the fusion rate and shorten the fusion time.

Objective To evaluate the efficiency of the application of array comparative genomic hybridization (array-CGH) in preimplantation genetic diagnosis or screening (PGD/PGS), and compare the clinical outcomes of different stage embryo biopsy. Methods The outcomes of 381 PGD/PGS cycles referred in the First Affiliated Hospital of Nanjing Medical University from July 2011 to August 2015 were retrospectively analyzed. There were 320 PGD cycles with 156 cleavage-stage-biopsy cycles and 164 trophectoderm-biopsy cycles, 61 PGS cycles with 23 cleavage-stage-biopsy cycles and 38 trophectoderm-biopsy cycles.Chromosomal analysis was performed by array-CGH technology combined with whole genome amplification.Single embryo transfer was performed in all transfer cycles.Live birth rate was calculated as the main clinical outcomes. Results The embryo diagnosis rate of PGD/PGS by array-CGH were 96.9%-99.1%. In PGD biopsy cycles, the live birth rate per embryo transfer cycle and live birth rate per embryo biopsy cycle were 50.0%(58/116) and 37.2%(58/156) in cleavage-stage-biopsy group, 67.5%(85/126) and 51.8%(85/164) in trophectoderm-biopsy group (both P<0.01). In PGS biopsy cycles, the live birth rate per embryo transfer cycle and live birth rate per embryo biopsy cycle were the same as 34.8%(8/23) in cleavage-stage-biopsy group, the same as 42.1%(16/38) in trophectoderm-biopsy group (both P>0.05). Conclusions High diagnosis rate and idea live birth rate are achieved in PGD/PGS cycles based on array-CGH technology.The live birth rate of trophectoderm-biopsy group is significantly higher than that of cleavage-stage-biopsy group in PGD cycles;the efficiency of trophectoderm-biopsy is better.

Cerebral hemorrhage accounts for about 10%-15% of all strokes, and its pathogenesis is complex. Currently, the main clinical treatment is mainly medical symptomatic treatment, including the use of antihypertensive drugs, hypoglycemic drugs, and hemostatic drugs, and surgical treatment is required in some cases, but there is still a lack of effective treatment. In recent years, traditional Chinese medicine and proprietary Chinese medicine have been widely accepted for their stable efficacy, high safety, and low cost. Rhei Radix et Rhizoma is one of the most commonly used herbal medicines for the treatment of cerebral hemorrhage. This paper summarizes the relevant literature on the treatment of cerebral hemorrhage with Rhei Radix et Rhizoma and finds that its active ingredients are mainly anthraquinones, such as emodin, Rhei Radix et Rhizoma acid, and Rhei Radix et Rhizoma phenol. The herbal formulas are Da Chengqitang, Shengdi Dahuangtang, Liangxue Tongyufang, and Naoxueshu oral liquid. The effects involve protecting the blood-brain barrier, promoting hematoma absorption, reducing inflammation levels, decreasing lactic acid accumulation at the bleeding site, and increasing the expression of brain-derived neurotrophic factors. The pathways involved include aquaporin 4 (AQP4), phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt), extracellular signal-regulated kinase 1/2 (ERK1/2), Toll-like receptor 4 (TLR4), nuclear transcription factor-κB (NF-κB), nuclear factor E2-related factor 2 (Nrf2), and Wnt3a/β-linked protein pathway. This paper summarizes the progress of clinical studies and animal experiments on the treatment of cerebral hemorrhage with active ingredients of Rhei Radix et Rhizoma and herbal compounds containing Rhei Radix et Rhizoma, so as to provide a reference for the treatment protocol of cerebral hemorrhage.
