Objective To evaluate the post-operative glucose level and insulin dose of patients undergoing total pancreatectomy.Methods From September 1980 to September 2014, 21 patients underwent total pancrea-tectomy in Peking Union Medical College Hospital, who were enrolled in our study.We reviewed the changes in their insulin dosage and glucose levels after operation, also summarized type and dose of insulin as well as glucose level in stable period.Results The required insulin dose reached peak within 4 days after surgery ( maximum dose 300 U/d).The average dose was (143.5 ±62.8) U/d and decreased gradually.During the perioperative period (needing parenteral nutrition), the blood glucose level fluctuated markedly (1.52-29.06 mmol/L) and the average level was (11.18 ±0.95) mmol/L.During the stable period ( without parenteral nutrition) , patients on average had (5.3 ±2.0) U of preprandial rapid-acting insulin and (8.1 ±2.9) U of long-acting insulin be-fore sleeping;the average fasting blood glucose was (6.69 ±1.48) mmol/L, 2 h postprandial blood glucose was (9.08 ±2.84) mmol/L, bedtime blood glucose was (9.66 ±2.49) mmol/L, and blood glucose level at night was (8.15 ±2.78) mmol/L.67%of the patients had 13 hypoglycemic episodes monthly on average.For those five followed-up patients, the average hemoglobin A1c was (6.15 ±1.20)%.Conclusions Patients undergoing total pancreatectomy may experience marked fluctuation of blood glucose level and short-term increase of insulin need which gradually decreases afterwards.After entering the stable period, the glucose level could be well-con-trolled but with frequent hypoglycemia.There is no diabetic ketoacidosis.

Objective To investigate the recent effect of full arthroscopic dual-beam reconstruction of the posterior cruciate ligament(PCL)using tibial Inlay technique.Methods From March 2007 to September 2009,17 PCL injured patients underwent full arthroscopic dual-beam PCL reconstruction using Inlay technique,including 16 males and 1 female,with an average age of 25 years(range,19-54).Of all cases,Lysholm score was(53.4±2.1)points,International Knee Documentation Committee(IKDC)rated C in 7,D in 10,and posterior drawer test(+)in 17.We used self-designed tibia tunnel drill system to produce the deep-limited bone tunnel.Follow-up began at 12 months after operation.Evaluate Lysholm knee score,IKDC rating,and posterior drawer test to compare the knee stability with that of preoperative.Observe the location of the bone block and healing by checking knee X-ray and spiral CT scan.Results Seventeen patients were followed up between 12 to 28 months,with an average of 17.8 months.In the last follow-up study,Lysholm score(93.5±1.7)points compared with that of preoperative was statistically significant different(P=0.016).IKDC rating of A grade in 15 cases,B in 2,compared with that of preoperative was statistically significant different(P=0.021).Posterior drawer test were negative in 15 cases,slight positive in 2.The X-ray and spiral CT scan showed the location of the bone block were perfect and healed well.Conclusion We can accurately produce the deep-limited bone tunnel by the tibia tunnel drill system with minor trauma,and the recent clinical effects of PCL reconstruction were pretty good.

Objective To investigate the three-dimensional structure of normal male canine prostat- ic duct and acinus system,and to study the mechanism of intraprostatic urinary reflux(IPUR)resulting from high pressure of the posterior urethra by experiment.Methods Using scanning electron microscopy (SEM)and corrosion casting methods,high pressure of the prostatic urethra was produced based upon IPUR in normal male canines.Acrylonitrile-butadiene-styrene(ABS)casting solution was injected into 8 Beagle canines'normal prostates to induce intraprostatie resin solution reflux.Results Six casting molds of nor- real canine prostate specimens were obtained,and the casting failed in 2.By corrosion and casting treatment, the prostate appeared to consist of several glandular lobes.The columnar apophyses of glandular surface were observed.The most glandular ducts pointed outward from urethral peristome.Each glandular duct system was made up of many bifurcated branches from the bough as a duct tree.More than 90% of the bifurcations were Y-shaped,and 6 bifurcated branches were rarely seen.The tip of the duct was vesicular.The diameter and length of the bough were(0.37?0.14)mm and(1.14?0.04)mm,respectively.The intersectional angle of urethra and peripheral glandular duct was the biggest.Peripheral glandular duct was perpendicular or con- verse to urinary flow.Peripheral glandular aeinus appeared elliptic and velvet.The mesh-like and crater-like depressions were shown on the surface of central glandular aeinus.Ejaculatory ducts independently and branchlessly entered the urethra.Conclusions The resin corrosion casting methods combined with SEM can clearly show the three-dimensional structure of normal male canine prostatic duct and acinus system. IPUR may easily occur in the peripheral glands from the morphological view.It is suggested that prostatitis occurs more commonly in peripheral glands,confirming a fact that high pressure of the posterior urethra can induce IPUR.

OBJECTIVETo evaluate the result of free transmidline bi-lobed scapular skin flap transplantation to repair massive soft tissue defects in upper and lower extremities.

METHODSFree transmidline bi-lobed scapular skin flap was designed according to the characteristics of scapular skin and its vasculature, and they were used to repair massive soft tissue defects in upper and lower extremities as a result of hot crush injury and avulsion injury in 9 patients. The survival of the flap, the blood supply, the color and elasticity of the flap, as well as scar contraction and impairment in function were observed after operation.

RESULTSThe largest flap formed with the horizontal branch and descending branch circumflex scapular artery were 31 x 14 cm and 22 x 16 cm, respectively. The horizontal branch went across the spinal midline for 10 cm. All skin flaps survived with good elasticity and without necrosis. The grafted skin was excellent in the appearance and elasticity, with no scar contracture , and function of the injured extremities recovered well 2 to14 months after the operation.

CONCLUSIONFree transmidline bi-lobed scapular skin flap is an ideal procedure for the repair of massive soft tissue defects in upper and lower extremities.

The present study investigated the influence of the methyl jasmonate and salicylic acid elicitors on the formation of phenylethanoid glycosides (PeG) in the suspension cultures of Cistanche deserticola. The results showed that methyl jasmonate and salicylic acid enhanced greatly the accumulation of PeG and echinacoside (Echin), but their optimum elicitation dosage and addition time were different. The yields of PeG and Echin were significantly increased in the presence of 5 micromol/L methyl jasmonate on day 14 (up to 2.59-fold and 3.82-fold, respectively), whereas treated with 50 micromol/L salicylic acid on day 28, the maximum content of them were, respectively, 2.71 and 3.16-fold higher than the untreated cell cultures.

OBJECTIVETo observe the effect of Chinese drugs for strengthening Pi, harmonizing Wei, and dispersing blood stasis (CDSPHWDBS) on the expression of gastric mucosal heat shock protein 70 (HSP70) in chronic atrophic gastritis (CAG) patients.

METHODSA total of 100 CAG patients were assigned to the control group and the treatment group by random digit table, 50 in each group. Patients in the control group took Folic Acid Tablet 10 mg each time, 3 times per day. Those in the treatment group took CDSPHWDBS, 100 mL each time, once per day. The treatment course was 6 months for all. Clinical symptoms and signs, endoscopic and histopathological changes were observed before and after treatment in the two groups. The expression of gastric mucosal HSP70 in CAG patients was determined using SP immunohistochemistry. Data were collected by HPIAS-1 000 pathological graphic analysis system, and its expression semi-quantitatively analyzed.

RESULTSThe total effective rate of clinical Chinese medical symptoms and signs was 88. 0% (44/50 cases) in the treatment group and 56. 0% (28/50 cases) in the control group, with significant difference between the two groups (P <0. 01). The improvement rate of endoscopic manifestations such as congestion and edema, erosion, bile regurgitation, pale gastric mucosa, exposed blood vessels, particles proliferation in the treatment group were superior to those in the control group (P <0. 05). The total effective rate of atrophy was 80. 0% (40/50 cases) in the treatment group and 54. 0% (27/50 cases) in the control group, with significant difference between the two groups (P<0. 01). The effective rate of intestinal metaplasia was 75. 0% (12/16 cases) in the treatment group and 33.3% (5/15 cases) in the control group, with significant difference between the two groups (P < 0. 05). The optical density value of gastric mucosal HSP70 was significantly elevated in the two groups after treatment (both P <0. 05). It was higher in the treatment group than in the control group after treatment with significant difference (P <0. 01).

CONCLUSIONCDSPHWDBS had obvious effect in treatment of CAG and could improve pathological changes of precancerous lesions possibly by promoting the expression of gastric mucosal HSP70 in CAG patients.

OBJECTIVETo explore the clinical application characteristics of sural neurocutaneous island flaps.

METHODSSural neurocutaneous island flaps were used to repair the skin defect accompanied bone and tendon exposure in the lower leg, around the ankle and foot in 21 cases, including 4 cases to repair the foreside of the foot back . Direct flap was used in 5 cases and reverse flap in 16 cases. Meanwhile the coverage and formation of sural nerve were surveyed together with the starting point of peroneal perforator.

RESULTSAll the 21 sural flaps were survived, including sural nerve (18 cases) anastomose 12 cases, single trunk 4 cases, double trunk 2 cases. The anastomose site of medial sural cutaneous nerve and the communicating branch of lateral sural cutaneous nerve was at the point of 11 - 14 cm above the ankle in 12 cases. The lower was the anastomose site, the shorter was the sural nerve. The site is 4 - 7 cm above the ankle in 15 out of 18 sural nerve perforator branch cases, and the other 3 cases is 10, 11, 11.5 cm above the ankle respectively.

CONCLUSIONSSural neurocutaneous island flaps are easy to separate. Major arteries are not injured. It is the ideal flap to repair the skin defect accompanied by bone and tendon exposure in lower leg, around ankle and foot. The nerve must be anastomosed when repairing the heel.

OBJECTIVETo compare the effectiveness and safety of different treatment modes for limited-stage small cell lung cancer(SCLC).

METHODSThe clinical data of 171 SCLC patients who had received different therapies were retrospectively analyzed.

RESULTSOf these 171 patients,55 had received concurrent radiochemotherapy,66 received sequential radiochemotherapy,and 50 received chemotherapy alone. For these 171 patients,the overall response rate(ORR)was 73.1%,overall survival(OS)and progression-free survival(PFS)were 23.5 months and 15.2 months,respectively,and the 1-,3-,and 5-year survival rates were 76.2%,30.4%,and 16.3%,respectively. For the concurrent group,sequential group,chemotherapy alone group,the median OS were 30.6,23.1,and 19.1 months,the median PFS were 19.7,13.3,and 11.5 months,and the 5-year survival rate was 28.7%,13.6%,and 9.4%,respectively(all P<0.05). The main toxic effects were myelosuppression,radiation pneumonia,and radiation esophagitis. The incidences of 1-2 grade myelosuppression were 92.7%,89.4%,and 92% in the concurrent group,sequential group,and chemotherapy alone group(P=0.25). For concurrent group and sequential group,the incidence of 1 grade radiation pneumonia were 47.2% and 50%,respectively(P=0.61),whereas the incidence of 1-2 grade radiation esophagitis were 94.5% and 75.8%(P=0.02). Multivariate analysis showed that gender,ECOG score,TNM stage,and thoracic radiation therapy were the independent prognostic factors for SCLC.

CONCLUSIONConcurrent radiochemotherapy is the treatment of choice for SCLC patients because it can improve the survival with tolerable toxicities.
